Description

Technical Field

[0001] The present application relates to the field of switch technology, and in particular to a highly reliable and safe seat cushion induction switch. Background Art

[0002] In the electric vehicle industry, to ensure safety and prevent children from accidentally turning the handlebar switch and starting the vehicle, a switch (a membrane switch: a circular pressure sensor mounted on a long film strip, connected by wires. The formed pressure sensor strip is installed under the electric vehicle seat and connected to the vehicle's circuit) is usually installed under the electric vehicle seat. However, this pressure sensor strip is expensive and has a short service life. The pressure sensor strip requires the electric vehicle seat to have a certain degree of waterproofness to protect the pressure sensor strip, which requires the internal waterproofness of the electric vehicle to be good, which increases the cost and needs to be improved.

[0036] The following is a further detailed description of this application in conjunction with Appendix 1-5.

[0037] Example 1

[0038] The embodiment of the present application discloses a highly reliable and safe seat cushion induction switch. Figure 1 and Figure 2 The high-reliability and safety seat cushion induction switch includes a seat body 1, a cover body 2 movably installed on the seat body 1, and a reset spring 3 installed on the seat body 1. One end of the reset spring 3 is connected to the seat body 1, and the other end faces the cover body 2 and abuts against the cover body 2. The reset spring 3 keeps the cover body 2 away from the seat body 1.

[0039] Reference Figure 1 and Figure 2 The seat body 1 includes a base 11, a circuit board 12 mounted and fixed on the base 11, and a cover 13 mounted and fixed on the base 11. A switch 4 for connecting the circuit is installed on the cover 13. The switch 4 controls whether the circuit is energized through a plug-in 19. A socket for plugging in the plug-in 19 is provided on the base of the electric vehicle to electrically connect with the control circuit. The seat body 1 is used to be installed under the seat cushion. When the driver sits on the seat cushion, the cover body 2 is pressed close to the seat body 1 and triggers the switch 4 to energize the circuit.

[0040] Reference Figure 2 and Figure 3The switch 4 is specifically attached to the circuit board 12. The switch 4 is mounted on the circuit board 12 so as to be mounted on the cover plate 13. There are multiple switches 4 installed, and multiple switches 4 are installed in parallel on the circuit board 12. In the embodiment of the present application, there are four switches 4 installed, and the four switches 4 are arranged in a row. The spacing between adjacent switches 4 is 2-5 cm, specifically 4 cm. The cover plate 13 is used to limit the circuit board 12 on the base 11. A waterproof cover 18 is installed on the circuit board 12. The waterproof cover 18 covers the switch 4. A receiving groove 5 is provided on the cover plate 13. The receiving groove 5 is for accommodating the waterproof cover 18. The switch 4 protrudes from the cover plate 13. A limiting groove 6 is provided on the cover plate 13. The groove wall of the limiting groove 6 abuts against the outer wall of the reset spring 3. One end of the reset spring 3 is accommodated in the limiting groove 6. The spring in the limiting groove 6 is replaceable. The spring with the corresponding elastic force can be replaced as needed to make the sensing force adjustable.

[0041] Reference Figure 1 and Figure 4 , a buckle 7 is fixed on the cover 2, and a positioning groove 8 for the buckle 7 is opened on the cover plate 13. When the reset spring 3 is in the natural state, the buckle 7 is accommodated and buckled in the positioning groove 8, and the buckle 7 always moves in the positioning groove 8. The buckles 7 are distributed in rows on both sides of the cover 2, with 4 buckles 7 on each side, which improves stability and enhances waterproof performance. A limiting ring 9 is fixed on the side of the cover 2 facing the base 11, and a positioning groove 8 is opened on the limiting ring 9 for the reset spring 3 (see Figure 3 ) accommodates the limiting groove 10. A contact protrusion 14 is fixed on the side of the cover 2 facing the base 11, and the contact protrusion 14 is located at the switch 4 (see Figure 3 ), the contact protrusion 14 is used to press the switch 4.

[0042] Reference Figure 1 A mounting protrusion 15 is fixed on the base 11, and a mounting hole 16 for mounting is opened on the mounting protrusion 15, and the diameter of the mounting hole 16 is 5.5 mm.

[0043] Reference Figure 1 The seat body 1 is provided with a wire outlet slot 20 for the power line to pass through.

[0044] The implementation principle of a high-reliability and safety seat cushion sensing switch in an embodiment of the present application is as follows: the seat body 1 is installed on the seat of an electric vehicle and is located under the seat cushion. When the driver sits on the seat cushion of the electric vehicle, the cover body 2 is forced to move toward the seat body 1 until the cover body 2 triggers the switch 4 to energize the circuit. The high-reliability and safety seat cushion sensing switch is simple to produce. It only requires producing a box and installing a spring and a switch 4 in the box. It has low cost and is easy to install. Compared with common pressure sensing strips, the electric vehicle anti-accidental-touch seat switch 4 has a longer service life, is waterproof, and has a wide sensing range. When one switch is damaged, there are multiple other switches to control whether the circuit is energized, which is safe and reliable.

[0045] Example 2

[0046] Reference Figure 5 The difference between this embodiment and embodiment 1 is that the component used to connect the circuit in this embodiment is a wire 17, which connects the circuit and the circuit board 12. The wire 17 is used to energize the switch 4. A wire outlet slot 20 is provided on the base body 1, and the wire outlet slot 20 is used to pass the power wire 17 out.

[0047] The implementation principle of Example 2 is: using the wire 17 to electrically connect with the control circuit, and controlling in a conventional wire connection manner is more reliable.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
