Abstract
Description
Technical Field
[0001] This utility model relates to a spring switch and a locking signal functional structure, belonging to the field of signal transmission in automotive locking systems. Background Technology
[0002] A spring switch is a signal device installed inside a car lock body. By deforming the spring structure, it can output a car lock signal.
[0003] Currently, in the field of locks such as car trunk locks, spring switches (fixed copper post, movable spring type) commonly function as an open circuit when unlocking and an open circuit when locking. That is, when unlocking, the spring contacts the copper post, and the circuit is connected. When locking, the locking plate pushes the spring away from the copper post, and the circuit is disconnected.
[0004] During vehicle upgrades at some automakers, there are different requirements for the locking signal output logic, meaning the output signal needs to be reversed (locking on and unlocking off). Currently, this is mostly achieved by adding microswitches. Obviously, the addition of microswitches, wiring harnesses, assembly, and soldering processes will significantly increase costs. Summary of the Invention
[0005] This invention aims to solve the aforementioned problems in the prior art by proposing a low-cost, stable, reliable, and durable spring switch and locking signal functional structure.
[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0007] A spring switch is characterized in that it has a terminal connection end and a forked double contact structure, the forked double contact structure including an actuating contact and an executing contact, the actuating contact being abutted and adapted to an external driving component and driven and controlled by it, and the executing contact following the action of the actuating contact to achieve contact and separation with a copper post.
[0008] Furthermore, the part of the actuating contact foot that abuts against the external driving component is designed with a stamped folding structure.
[0009] Furthermore, the surface of the spring switch has multiple reinforcing ribs.
[0010] A locking signal functional structure is configured in a car lock body and is driven and controlled by a rotating plate of the locking mechanism to realize the output of the car lock signal. It includes a switch sub-assembly housing, terminals and copper pillars mounted on a base plate. The special feature is that the switch sub-assembly housing is equipped with the above-mentioned spring switch.
[0011] Furthermore, one end of the spring switch is connected to the terminal via a terminal connection end, and the other end of the spring switch is designed as a forked double-contact structure. The forked double-contact structure includes an actuating contact, which is adapted to and driven by the rotating plate. The forked double-contact structure also includes an execution contact, which follows the action of the actuating contact to achieve contact and separation with the copper pillar.
[0012] Furthermore, the part where the actuating contact foot abuts and adapts to the rotating plate is designed with a stamped folding structure.
[0013] Furthermore, the spring switch has a housing fixing end and is mounted on the switch sub-assembly housing through the housing fixing end.
[0014] Furthermore, the copper pillar is located outside the spring switch and remains in contact with the actuating contact of the spring switch when the lock is locked.
[0015] Furthermore, the surface of the spring switch has multiple reinforcing ribs.
[0016] Furthermore, the actuation contact of the spring switch is provided with reinforcing ribs.
[0017] This utility model discloses a spring switch and its locking signal functional structure. The spring switch is transformed from a traditional single-leg contact type to a forked double-contact structure, giving each contact a different function during the locking process. Specifically, the actuating contact contacts and is driven by the locking plate, while the executing contact, driven by the actuating contact, contacts and engages with the copper post. This functionally differentiated double-contact spring structure increases the buffer tolerance of the spring during opening and closing, improving the overall durability and stability of the spring. Simultaneously, it achieves low-cost signal requirement conversion, enabling replacement and upgrades in locks at a very low cost, significantly reducing modification costs and development time.

Detailed Implementation
[0022] The present invention will now be described in detail with reference to the accompanying drawings.
[0023] Example 1
[0024] A spring switch 3 includes a spring body, a terminal connection end 31, a housing fixing end 32, and a forked double-contact structure disposed on the spring body. The forked double-contact structure includes an actuating contact 33 and an actuating contact 34. The actuating contact 33 is driven by an external driving member, and the actuating contact 34 is used to contact a copper post. The length of the actuating contact 33 is greater than that of the actuating contact 34.
[0025] When the actuating contact 33 is driven by the driving member to move and deform, the actuating contact 34 on one side will move and deform accordingly, so that the actuating contact 34 moves closer to the copper pillar on one side until it makes contact.
[0026] To avoid cutting and grinding between the actuating contact 33 and the driving component during contact, the part of the actuating contact 33 that contacts the driving component is designed as a stamped and folded structure 33a.
[0027] Example 2
[0028] A locking signal functional structure for an automotive lock is configured inside the lock body of the automotive trunk to transmit a locking signal. It includes a base plate 4 and a switch sub-assembly housing 2, a spring switch 3, a terminal 1, and a copper pillar 5 mounted on the base plate 4. It also includes a rotating plate 6 mounted on the base plate 4 to form a locking mechanism.
[0029] The spring switch 3 has a housing fixing end 32 and is mounted on the switch sub-assembly housing 2 through the housing fixing end 32; the spring switch 3 has a terminal connection end 31 and contacts the terminal 1 through the terminal connection end 31, and the copper pillar 5 contacts the substrate 4. The spring switch 3 is provided with a forked double contact structure, which includes an actuating contact 33 and an executing contact 34. The actuating contact 33 is used to abut against the rotating plate 6, and the executing contact 34 is used to contact the copper pillar 5. The part of the actuating contact 33 that contacts the rotating plate 6 is set with a stamped and folded structure, which can avoid cutting and wear on the surface of the rotating plate 6 when it contacts the rotating plate 6 at multiple angles. The surface of the spring switch 3 is provided with multiple reinforcing ribs 35 to improve the overall strength of the spring switch 3 and ensure that it maintains its shape stability during repeated deformation. The copper pillar 5 is located outside the spring switch 3. When the lock is closed, the actuating contact 34 of the spring switch 3 always remains in contact with the copper pillar 5.
[0030] When the lock is locked, the latch pushes the rotating plate 6 to rotate, and the rotating plate 6 pushes the actuating contact 33 of the spring switch 3 to rotate, thereby causing the actuating contact 34 of the spring switch 3 to contact and conduct with the copper post 5, forming a closed circuit and transmitting the locking signal.
[0031] The spring switch and locking signal functional structure of this utility model achieves low-cost signal requirement conversion of the locking signal functional structure by changing the spring switch to a forked double-contact structure, so that it contacts the copper pillar and the card plate respectively.
[0032] During each locking and unlocking process, the rotating plate of a luggage lock experiences varying rotation speeds and strokes. Higher rotation speeds and strokes result in greater deformation and impact on the spring clip, necessitating strong stability to ensure normal function and stable signal transmission throughout its lifespan. Traditionally, a single-leg spring clip has its front and back sides in contact with the rotating plate and copper pillar respectively, negatively impacting its stability, durability, and lifespan. This new design employs a forked double-contact structure with functional division of labor between the two contacts. This double-leg design effectively increases the spring clip's buffer tolerance, while the split design enhances its overall resilience and stability.
[0033] This utility model is not limited to the embodiments discussed above. The above description of specific embodiments is intended to describe and illustrate the technical solutions involved in this utility model. Obvious variations, substitutions, or combinations based on the teachings of this utility model should also be considered to fall within the protection scope of this utility model.
