    description
    The present invention provides a circuit board positioning device for electric drives.
    Reference is made to FIGS. 1 and 2. The electric drive 10 is used to drive a valve or an air flap, a connection block 111 and a control unit 20 being arranged in its cavity body 11.
    The control unit 20 consists of a plurality of circuit boards 21 in which, as shown in FIGS. 3 and 4, a plurality of positioning elements and screw elements are screwed together and combined.
    However, if the circuit boards 21 of the control unit 20 fail, the plurality of positioning elements 22 and screw elements must be dismantled one after the other. The maintenance and repair process is extremely cumbersome and time-consuming.
    With the present invention, assembly and positioning, as well as maintenance, repair and replacement of the circuit boards can be carried out more quickly and conveniently to effectively improve work efficiency and thus reduce maintenance costs.
    A comprehensive and enabling disclosure of the present invention, including its best mode, for one skilled in the art is set forth in more detail in the remainder of the specification, which includes reference to the accompanying figures, in which:

    Detailed description of the exemplary embodiments
    Reference is made to Figs. 5 to 9, which show a first embodiment comprising:
    a floor member 30 positioned in the cavity body of an electric drive;
    a first block body 40, which is concavely curved and made of a heat-resistant insulating material such as phenoplast, with its underside being on the left side of the floor member 30, the first block body having a first outer surface 41 and a first inner surface 42, the first inner surface 42 is provided with a plurality of first positioning portions 421 arranged in parallel from top to bottom, the first positioning portions 421 having a groove shape;
    a second block body 50 made of a heat-resistant insulating material such as phenoplast and concavely curved with its underside on the right side of the bottom member 30, the second block body having a second outer surface 51 and a second inner surface 52, the second inner surface 52 is provided with a plurality of second positioning sections 521, which are arranged parallel to one another from top to bottom and correspond to the first positioning sections 421, the second positioning sections 521 having a groove shape.
    Reference is made to FIGS. 10-13. In use, the base element 30 is screwed to the cavity body 11 of the electric drive by means of screw elements, then the circuit boards 60 are inserted one after the other into the first positioning sections 421 and the second positioning sections 521, which correspond to the first block body 40 and the second block body 50. When a circuit board 60 is in a defective state, it is only necessary to easily pull out the defective circuit board from the first and second block bodies 40, 50 as shown in Fig. 13, which is very convenient in operation and shortening the dismantling time.
    Preferably, the first and second block bodies 40, 50 are made of glass fiber reinforced nylon.
    In summary, it can be stated that the invention achieves the advantageous effects of simple assembly and convenient maintenance or repair.
    In addition, since the circuit boards generate thermal energy during operation, the resulting excessive heat often causes the circuit to crash. For this reason, the bottom element 30 can be made of a material with good thermal conductivity in order to support the dissipation of heat so that the temperature inside the hollow body of the electric drive is as balanced as possible in order to avoid local overheating.
    Preferably, the material of the bottom element 30 consists of aluminum.
    Reference is made to FIGS. 14 and 15, which show a second embodiment. The difference between this embodiment and the first embodiment is that in this embodiment, a first heat dissipation element 70 is also provided, which consists of a material with good thermal conductivity such as aluminum and in the first positioning sections 421 and the second positioning sections 521, which are connected to the first Block body 40 and the second block body 50 correspond, is inserted, its mounting position can be selected near a strongly heating circuit board, whereby the heat is dissipated by conduction and thus the temperature in the cavity body is equalized as quickly as possible.
    Reference is made to FIGS. 16 to 18, which show a third embodiment. The difference between this exemplary embodiment and the first exemplary embodiment is that in this exemplary embodiment the first block body 40 is provided with a first slotted hole 43, the first slotted hole 43 going through the first outer surface 41 and the first inner surface 42, around a second heat dissipation element 44 to be able to position, wherein the second heat dissipation element 44 is made of a material with good thermal conductivity; the second block body 50 being provided with a second slotted hole 53, the second slotted hole 53 going through the second outer surface 51 and the second inner surface 52 in order to be able to position a third heat dissipation element 54, which is also made of a material with good thermal conductivity such as aluminum , through which the temperature inside the cavity body can be equalized more quickly.
    Reference is made to Fig. 19, which shows a fourth embodiment. The difference between this embodiment and the third embodiment is that in this embodiment, a fourth heat dissipation element 80 is also provided, which consists of a material with good thermal conductivity such as aluminum and in the first positioning sections 421 and the second positioning sections 521, which are connected to the first Block body 40 and the second block body 50 correspond, is inserted.
    While the invention has been explained in terms of its preferred embodiment, it should be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
