Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment: Please refer to Figures 1-4 A double-pole single-throw tactile switch for new energy vehicles as shown, including a snap-on housing 1 and a base housing 2. The base housing 2 is snap-fitted inside the snap-on housing 1. A conduction component 4 is arranged in the base housing 2. A dual-path component 3 for connecting two transmission paths is embedded and installed in the base housing 2. A dome switch 5 is snap-connected above the inner wall of the base housing 2. A push button 8 is snap-connected between the top of the base housing 2 and the snap-on housing 1;

[0027] Among them, the dual-path component 3 enables the double-pole single-throw (dual-circuit) switch to provide precise control capabilities, meeting the increasing requirements of new energy vehicles for electrification and intelligence. And the dual-path component 3 can provide multiple circuit protection functions, such as overcurrent, over-temperature, and overheat shutdown protection, etc., enhancing the safety of the entire vehicle circuit system; it is particularly suitable for application in the double-protection circuit of new energy devices and can double-protect the starting circuit and control system in actual operation applications.

[0028] The dome switch 5 is located above the connection block 301, and the connection block 301 is located below the push button 8;

[0029] Among them, when in use, the push button 8 is pressed. The push button 8 squeezes the dome switch 5, causing the dome switch 5 to deform downward. At this time, the dome switch 5 squeezes the connection plate 303, driving the connection plate 303 and the two conduction pieces 302 on the connection plate 303 to move downward synchronously, so that the two conduction pieces 302 simultaneously contact the second terminal 402 and the second contact 404 on the second terminal 402, realizing simultaneous connection of the two paths;

[0030] When the pressing on the pressing key 8 is released, the two conductive members 302 will simultaneously lose contact with the second terminal 402 and the second contact 404 on the second terminal 402, achieving the benefit of double - path synchronous disconnection. After use, the dome switch 5 will reset to assist the pressing key 8 in resetting;

[0031] Furthermore, the dome switch 5 has the advantages of smaller volume, longer lifespan, and improved overall compatibility of the device compared with the springs used in traditional devices, thus achieving the benefit of extending the service life of the device;

[0032] The double - path component 3 includes a connecting block 301. On one side of the inner cavity of the connecting block 301, conductive members 302 are symmetrically installed. The conductive members 302 penetrate through the connecting block 301 and extend to the bottom of the connecting block 301. A connecting plate 303 is arranged between the two conductive members 302;

[0033] Among them, the connecting plate 303 is made of plastic material to prevent the two conductive members 302 from penetrating each other;

[0034] The conduction component 4 includes two first terminals 401 and a second terminal 402. On one side of the bottom of the inner cavity of the clamping housing 1, the first terminals 401 are symmetrically arranged. On one side of the bottom of the inner cavity of the clamping housing 1, the second terminal 402 is symmetrically arranged;

[0035] On the tops of the two first terminals 401, first contacts 403 are respectively arranged. On the tops of the two second terminals 402, second contacts 404 are respectively arranged.

[0036] In this embodiment, specifically referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the two first terminals 401 are horizontally parallel to the two second terminals 402. One ends of the two first terminals 401 and the second terminal 402 respectively penetrate through the inner wall of the base housing 2 and extend to the outside of the base housing 2;

[0037] The bottom surfaces of one ends of the two conductive members 302 located below the connecting block 301 are in contact with the first contact 403 or the second contact 404, and the other ends of the two conductive members 302 are not in contact with the first contact 403 or the second contact 404;

[0038] Among them, during use, as the pressing key 8 moves downward, the pressing key 8 will squeeze the dome switch 5 downward, causing the dome switch 5 to deform downward and pressing the connecting plate 303 and the conductive members 302 on the connecting plate 303 to move downward, so that one ends of the two conductive members 302 that are not in contact with the second contact 404 or the first contact 403 come into contact with the second contact 404 or the first contact 403, achieving the connection between the two paths in the device;

[0039] In addition, the two conductive members 302 are not limited to the above connection method. During the production process, the conductive members 302 can also be set as follows: when the two connecting plates 303 drive the conductive members 302 to press down, one conductive member 302 connects the two first contacts 403, and one conductive member 302 connects the two second contacts 404, achieving the effect of multi-bit conduction and rapid response.

[0040] In this embodiment, specifically refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , on the upper parts of the two mutually symmetric outer walls of the base housing 2 in the vertical direction, positioning blocks 6 are respectively provided, and on the two mutually symmetric outer walls of the clamping housing 1 in the vertical direction, clamping grooves 7 are respectively provided, and the positioning blocks 6 are respectively clamped in the two clamping grooves 7;

[0041] Among them, the base housing 2 and the positioning block 6 are integrally die-cast to ensure the stability between the positioning block 6 and the base housing 2.

[0042] In this embodiment, specifically refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the conductive member 302 is connected to the first terminal 401;

[0043] Among them, when the dual-channel component 3 is fitted and installed in the base housing 2, one end of the two conductive members 302 remains connected to the first terminal 401 to ensure the stability between the conductive member 302 and the first terminal 401.

[0044] In this embodiment, specifically refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a waterproof ring 9 is clamped on the top of the base housing 2, and the bottom of the pressing key 8 contacts the top of the waterproof ring 9;

[0045] Among them, during the splicing and installation of the device, the waterproof ring 9 is located between the pressing key 8 and the base housing 2. When the clamping housing 1 is buckled on the base housing 2, the pressing key 8 and the waterproof ring 9 are simultaneously tightly clamped between the clamping housing 1 and the base housing 2, achieving the benefit of improving the waterproof performance of the device.

[0046] When a double-pole single-throw tactile switch for a new energy vehicle is working, when in use, the pressing key 8 is pressed, and the pressing key 8 squeezes the dome sheet 5, causing the dome sheet 5 to deform downward. At this time, the dome sheet 5 squeezes the connecting plate 303, and the connecting plate 303 and the two conductive members 302 on the connecting plate 303 are pressed to move downward synchronously, so that the two conductive members 302 simultaneously contact the second terminal 402 and the second contact 404 on the second terminal 402, achieving the benefit of simultaneous double-channel connection;

[0047] When the pressing on the pressing key 8 is withdrawn, the two conductive members 302 will simultaneously lose contact with the second terminal 402 and the second contact 404 on the second terminal 402, achieving the benefit of double-channel synchronous disconnection. After use, the dome sheet 5 will be reset to assist the pressing key 8 in resetting.

[0048] In a switch space with a relatively small volume, the structural design is extremely precise. In actual operation, the switch can be synchronously turned on and off instantaneously. The structural design and manufacturing process of this switch can achieve lean production.

[0049] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
