Problems solved by technology

[0002] In recent years, many countries and enterprises are vigorously developing and promoting new energy vehicles, especially electric vehicles. More and more car door systems (side doors and trunk doors) have electric opening and closing functions, but many electric doors are not equipped with The anti-pinch protection device has great safety hazards. For example, during the closing process of the car door, people accidentally put their fingers, arms, heads or other objects in the gap of the car door. It is very likely to cause personal injury or even life-threatening. Under this background, there is an urgent need for an anti-trap protection device that is responsive, feasible to manufacture, easy to install, and has a wide range of applications, so that the opening and closing of the door system is safer and more reliable. , to eliminate the above security risks

Embodiment 1

[0029] Such as figure 1 with Figure 9 As shown, the contact anti-pinch device mainly includes an insulating package body 100, an upper conductive rubber 200, a lower conductive rubber 300, a sheath wire 400, a conductive connector 500, a front end 600 and an end connector 700, and a conductive connector 500 Connected to one side of the insulating packaging material body 100, the sheathed wire 400 is covered on the outside of the conductive connector 500, the front end 600 is located at the front end of the insulating packaging material body 100, and the terminal head 700 is located at the rear end of the insulating packaging material body 100. The rubber 200 and the lower conductive rubber 300 each wear a conductive wire 800 and communicate with the external controller. For the convenience of installation, the ends of the front head 600 and the end head 700 are shaped like mushroom nails. On the one hand, they are connected through the ends. Combined with adhesive tape, the ...

Embodiment 2

[0032] Most of the structure of this embodiment is the same as that of Embodiment 1, as an optimization, such as Figure 4 As shown, the connection between the upper end of the curved deformation arc angle 1001 and the upper conductive rubber 200 has an upper protrusion 1002, and the connection between the lower end of the bending deformation arc angle 1001 and the lower conductive rubber 300 has a lower protrusion 1003, and the upper contact surface 2001 The length of the lower contact surface 3001 is greater than the length between the upper protrusions 1002 on both sides, and the length of the lower contact surface 3001 is greater than the length between the lower protrusions 1003 on both sides. Here, the upper protrusion 1002 and the lower protrusion 1003 can be used to facilitate the fixed connection of the upper conductive The rubber 200 and the lower conductive rubber 300 can significantly increase the contact length position between the upper contact surface 2001 and th...

Embodiment 3

[0034] As an improved optimization, such as Figure 5 As shown, the upper conductive rubber 200 is semicircular and has an arc surface 2002. There is a contact protrusion 2003 at the lower end of the middle position of the upper conductive rubber 200. The lower part of the lower conductive rubber 300 is embedded in the insulating packaging body 100. The lower conductive rubber The upper end of 300 has an inner concave arc surface 3002 that matches with the contact protrusion 2003, and the two sides of the lower conductive rubber 300 have round side contact parts 3003 that are in contact with the arc surface 2002 of the upper conductive rubber 200. The arc surface 2002 of the rubber 200 is covered with both sides of the contact deformation cavity 900. The concave arc surface 3002, the contact protrusion 2003, the circular side contact portion 3003 and the arc surface 2002 can ensure contact from multiple angles. The anti-pinch angle can be significantly increased, which can be ...

Abstract

The invention belongs to the technical field of automobile anti-pinch components, and provides a contact type anti-pinch device. The contact type anti-pinch device comprises an insulating packing material body, upper conductive rubber and lower conductive rubber, wherein a contact deformation cavity is formed in the insulating packing material body; the upper conductive rubber is positioned at theupper end of the contact deformation cavity; the lower conductive rubber is positioned at the lower end of the contact deformation cavity; a conductive wire penetrates through each of the upper conductive rubber and the lower conductive rubber, and the upper conductive rubber and the lower conductive rubber communicate with an external controller; and when the packing material body is extruded, the upper conductive rubber and the lower conductive rubber are extruded and contacted with each other to form a contact resistor, and the contact resistor is electrically connected to the external controller through the conductive wires. The contact type anti-pinch device has the advantages that the contact area is large, so that the contact resistance is smaller, the anti-pinch angle is large, the anti-pinch sensitivity is higher, and the contact type anti-pinch device is suitable for smaller space arrangement, such as automobile side door metal plates; the selectable range of initial resistance of a loop is wide, and the resistance after contact is less than or equal to 400 omega; and the development cost is low, the processing is convenient, and the contact type anti-pinch device is matched with an automobile door more attractively.
