Technical Field
[0001] This utility model relates to the field of emergency power supply technology, and more specifically, to an emergency power supply for automotive central locking systems. Background Technology
[0002] A car central locking emergency power supply is a backup power device that ensures the central locking system functions normally when the vehicle's main power supply fails. Portable emergency power supplies are one type of such device; when the vehicle's main power supply fails and the central locking system becomes unusable, a portable emergency power supply can quickly connect to the vehicle's electrical system and temporarily power the central locking system.
[0003] Currently available portable emergency power supplies for car central control systems generally use alligator clips. When the clip is in a closed storage state, if the user accidentally presses the power switch, a conductive circuit will still be formed, causing the metal part of the clip to become electrified. If a person accidentally touches the metal clip while it is electrified, it can easily cause an electric shock accident. Utility Model Content
[0004] Based on the aforementioned technical problem that "existing portable emergency power supplies for car central locking systems generally use alligator clip-type conductive clips, when the clips are in a closed storage state, if the user accidentally presses the power switch, a conductive circuit will still be formed even though the clips are in a closed state, causing the metal part of the clips to become electrified. If a person accidentally touches the metal clips while they are electrified, it can easily cause an electric shock accident," this utility model proposes an emergency power supply for car central locking systems.
[0005] This utility model proposes an emergency power supply for a car central locking system, comprising a positive clamping assembly and a negative clamping assembly, a spring, a first conductive element, a second conductive element, an elastic telescopic element, a third conductive element, and a fourth conductive element;
[0006] The clamping assembly includes a first clamping body and a second clamping body, which are rotatably connected.
[0007] The two ends of the spring are fixedly connected to the first clamp and the second clamp, respectively.
[0008] The first conductive component is fixedly installed inside the second clamp.
[0009] The second conductive component is fixedly installed inside the second clamp and is electrically connected to the first conductive component.
[0010] The elastic telescopic component is fixedly installed at the end of the second conductive component and slidably connected to the inner wall of the clamping assembly, and the elastic telescopic component maintains an electrical connection with the second conductive component.
[0011] The third conductive component is fixedly installed inside the clamping assembly;
[0012] The fourth conductive element is fixedly installed inside the clamping assembly and electrically connected to the third conductive element;
[0013] The first clamp and the second clamp are both fixedly connected to a conductive clamp on their relatively close sides, and the conductive clamp is electrically connected to the fourth conductive component.
[0014] When the first and second clamps are not under pressure, the two conductive clamps are in a closed state, and the elastic telescopic member and the third conductive member remain in a non-contact state. When the first and second clamps are under pressure, the two conductive clamps are in an open state, and the elastic telescopic member and the third conductive member form contact and conduction.
[0015] Preferably, it also includes an emergency power supply body, the terminals of which are fixedly connected to power cords for positive and negative connection.
[0016] Preferably, the first conductive element includes a conductive plate with its end passing through the second clamp and extending to its outer side, and maintaining an electrical connection with one of the power lines.
[0017] Preferably, the inner wall of the second clamp is provided with an insulating groove, and the conductive plate is fixedly connected in the insulating groove.
[0018] Preferably, the second conductive element includes an arc-shaped conductive sheet, and the inner wall of the second clamp is provided with an installation groove. The conductive sheet is fixedly connected in the installation groove. When the first clamp and the second clamp rotate in opposite directions, the conductive sheet can slide along the inner wall of the first clamp.
[0019] Preferably, the elastic telescopic component includes a conductive arc plate and a conductive arc sleeve. The conductive arc plate has an arc-shaped structure and its ends are electrically connected to arc-shaped conductive sheets. The ends of the conductive arc plate are provided with limiting portions. The inner wall of the conductive arc sleeve is provided with an adjustment groove. The limiting portion slides in conjunction with the inner wall of the adjustment groove. The inner and outer side walls of the conductive arc plate are both provided with arc grooves. The conductive arc sleeve slides in conjunction with the arc grooves respectively.

[0022] Preferably, both the outer walls of the first clamp and the second clamp are provided with anti-slip grooves.
[0023] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:
[0024] 1. When the first and second clamps are not compressed, the two conductive clamps are closed under the elastic force of the spring sheet. At this time, the conductive arc sleeve and the connecting guide plate remain in a non-contact state, and the entire circuit is in an open state. Even if the power switch is accidentally pressed, a conductive circuit will not be formed, and the conductive clamps will not be energized, reducing the risk of electric shock caused by accidental contact and improving the safety of emergency power supply use.
[0025] 2. By setting a spring, the opening angle of the two conductive clamps can be adjusted according to the rotation angle of the first clamp and the second clamp, so as to avoid the opening angle of the two conductive clamps being too large, which would cause the conductive arc sleeve to fail to connect with the connecting guide plate and cause a short circuit.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0035] like Figures 1-3 As shown, an emergency power supply for a car central locking system includes a positive clamping assembly and a negative clamping assembly 3, a spring 7, a first conductive element, a second conductive element, an elastic telescopic element, a third conductive element, and a fourth conductive element;
[0036] The clamping assembly 3 includes a first clamping body 4 and a second clamping body 5, which are rotatably connected.
[0037] The two ends of the spring piece 7 are fixedly connected to the first clamp 4 and the second clamp 5, respectively.
[0038] The first conductive component is fixedly installed inside the second clamp 5;
[0039] The second conductive component is fixedly installed inside the second clamp 5 and is electrically connected to the first conductive component.
[0040] The elastic telescopic component is fixedly installed at the end of the second conductive component and slidably connected to the inner wall of the clamping assembly 3, and the elastic telescopic component maintains an electrical connection with the second conductive component.
[0041] The third conductive component is fixedly installed inside the clamping assembly 3;
[0042] The fourth conductive element is fixedly installed inside the clamping assembly 3 and electrically connected to the third conductive element;
[0043] Conductive clamps 6 are fixedly connected to the relatively close side of the first clamp 4 and the second clamp 5, and the conductive clamps 6 are electrically connected to the fourth conductive component.
[0044] When the first clamp 4 and the second clamp 5 are not under pressure, the two conductive clamps 6 are in a closed state, and the elastic telescopic member and the third conductive member remain in a non-contact state. When the first clamp 4 and the second clamp 5 are under pressure, the two conductive clamps 6 are in an open state, and the elastic telescopic member and the third conductive member form contact and conduction.
[0045] In the above structure, when the first clamp 4 and the second clamp 5 are not compressed, the two conductive clamps 6 are in a closed state under the elastic force of the spring piece 7. At this time, the conductive arc sleeve 19 and the connecting guide piece 14 remain in a non-contact state, and the entire circuit is in a disconnected state. Even if the power switch is accidentally pressed, a conductive circuit will not be formed, and the conductive clamps 6 will not be energized, reducing the risk of electric shock caused by accidental contact by the human body and improving the safety of emergency power supply use.
[0046] like Figure 1 and Figure 2 As shown, it also includes an emergency power supply body 1. The terminals of the emergency power supply body 1 are fixedly connected to power lines 2 for positive and negative connection. The first conductive element includes a conductive plate 12, the end of which passes through the second clamp 5 and extends to its outer side, and is electrically connected to one of the power lines 2.
[0047] like Figure 3 and Figure 4 As shown, an insulating groove 10 is formed on the inner wall of the second clamping body 5, and the conductive plate 12 is fixedly connected in the insulating groove 10. The insulating groove 10 can effectively isolate the conductive plate 12 from the second clamping body 5 to prevent current leakage.
[0048] like Figure 3 As shown, the second conductive element includes an arc-shaped conductive sheet 13. The inner wall of the second clamp 5 is provided with an installation groove 9. The conductive sheet 13 is fixedly connected in the installation groove 9. When the first clamp 4 and the second clamp 5 rotate toward each other, the conductive sheet 13 can slide along the inner wall of the first clamp 4.
[0049] like Figure 7 As shown, the elastic telescopic component includes a conductive arc plate 16 and a conductive arc sleeve 19. The conductive arc plate 16 has an arc-shaped structure and its end is electrically connected to the arc-shaped conductive sheet 13. The end of the conductive arc plate 16 is provided with a limiting part 18. The inner wall of the conductive arc sleeve 19 is provided with an adjustment groove 20. The limiting part 18 is slidably engaged with the inner wall of the adjustment groove 20. The inner and outer side walls of the conductive arc plate 16 are both provided with arc grooves 17. The conductive arc sleeve 19 is slidably engaged with the arc grooves 17 respectively. A spring 21 is fixedly connected to the inner wall of the conductive arc sleeve 19. The end of the spring 21 is fixedly connected to the limiting part 18.
[0050] By setting the spring 21, the opening angle of the two conductive clamps 6 can be adjusted according to the rotation angle of the first clamp 4 and the second clamp 5.
[0051] like Figure 3 As shown, the third conductive component includes an arc-shaped connecting guide plate 14, which is fixedly connected inside the first clamp 4.
[0052] like Figure 3 and Figure 5 As shown, the fourth conductive component includes a connecting guide plate 15. A connecting groove 11 is provided on the inner wall of the first clamp 4. The connecting guide plate 15 is fixedly connected in the connecting groove 11. One end of the connecting guide plate 15 is electrically connected to the connecting guide piece 14, and the other end is electrically connected to the conductive clamp 6.
[0053] like Figure 2 As shown, anti-slip grooves 8 are provided on the outer walls of both the first clamping body 4 and the second clamping body 5.
[0054] Working principle: When the first clamp 4 and the second clamp 5 are not pressed, the two conductive clamps 6 are in a closed state under the elastic force of the spring piece 7. At this time, the conductive arc sleeve 19 and the connecting guide piece 14 are in a non-contact state, and the entire circuit is in an open state. Even if the power switch is accidentally pressed, a conductive circuit will not be formed, and the conductive clamps 6 will not be energized.
[0055] When an emergency power supply is needed, pressure is applied to the first clamp 4 and the second clamp 5 to overcome the elasticity of the spring 7, causing the two conductive clamps 6 to open. During this process, the arc-shaped conductive sheet 13 drives the conductive arc plate 16 to move. The conductive arc plate 16 pushes the conductive arc sleeve 19 to contact the connecting guide sheet 14 through the spring 21, forming a contact connection.
[0056] Current is conducted from the emergency power supply body 1 through the power cord 2, conductive plate 12, arc-shaped conductive sheet 13, conductive arc plate 16, conductive arc sleeve 19, connecting guide plate 14, and connecting guide plate 15 to the conductive clamp 6, thereby realizing the power supply of the emergency power supply.
[0057] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
