Description

Technical Field

[0001] This utility model relates to the field of vehicle door structure technology, and in particular to a vehicle door lock switch protection mechanism. Background Technology

[0002] Car door locks are a core component of a vehicle's safety system. They function more than just as a simple switch; they serve multiple purposes, including theft prevention, security of items inside the vehicle, and passenger safety. Their reliability directly impacts passenger safety. The lock's bolt and latch engage to secure the door to the door frame, firmly holding the door in place. This prevents passengers from falling out of the car if the door is suddenly opened.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: When closing car doors, drivers often use considerable force, causing a strong impact between the door lock and the latch. Due to the lack of appropriate cushioning devices, this may damage the door lock or deform the latch, creating significant safety hazards and affecting the user experience.

[0004] Therefore, those skilled in the art have provided an automotive door lock switch protection mechanism to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a car door lock switch protection mechanism. Its advantage is that it is designed with a corresponding buffer device to protect the door lock switch. When the car door lock comes into contact with the latch ring, it will come into contact with the push plate. The impact force is effectively mitigated by the setting of the corresponding shock-absorbing plate and spring damper, thus protecting the car door lock and latch.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car door lock switch protection mechanism, including a door frame and a switch protection latch, the switch protection latch including a fixing plate, a latch ring fixedly disposed on the outer side of the fixing plate, a door lock structure being engaged on one side of the latch ring, an inner box fixedly disposed on the inner side of the fixing plate, four spring dampers fixedly disposed inside the inner box, a push plate fixedly connected to the four spring dampers, a shock-absorbing plate fixedly connected to the side of the push plate near the door lock structure located on the outer side of the fixing plate, three moving holes fixedly disposed on the fixing plate, the push plate passing through the moving holes to reach the outer side of the fixing plate.

[0007] Furthermore, threaded holes are fixedly provided at the four corners of the fixing plate, and screws are fixedly provided on the four threaded holes. The four screws pass through the threaded holes and are threadedly connected to the door frame.

[0008] Furthermore, rubber sleeves are fitted on both sides of the locking ring.

[0009] Furthermore, a sliding groove is fixedly provided on the fixed plate, and a slider is slidably connected on the two sliding grooves.

[0010] Furthermore, the two sliders are fixedly connected to a support plate at a position outside the fixed plate.

[0011] Furthermore, the support plate is fixedly connected to the side of the door lock structure and the outside of the push plate.

[0012] Furthermore, the inner box is located inside the door frame.

[0013] This utility model has the following beneficial effects:

[0014] This utility model proposes a car door lock switch protection mechanism, which is designed with a buffer device to effectively reduce the impact force generated when the car door is hit hard, thus protecting the door lock switch. When the door lock comes into contact with the latch, the door lock's locking block will contact the push plate and impact its shock-absorbing plate. Subsequently, with the deformation of the spring damper, the impact force is absorbed, thereby protecting the door lock and latch and reducing the probability of damage. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This utility model provides an embodiment of a car door lock switch protection mechanism, including a door frame 1 and a switch protection latch 2. The switch protection latch 2 includes a fixing plate 202, a latch ring 201 fixedly disposed on the outer side of the fixing plate 202, a door lock structure 3 snapped onto one side of the latch ring 201, an inner box 211 fixedly disposed on the inner side of the fixing plate 202, four spring dampers 212 fixedly disposed inside the inner box 211, push plates 209 fixedly connected to the four spring dampers 212, and three moving holes 205 fixedly disposed on the fixing plate 202. The push plate 209 passes through the moving hole 205 to reach the outside of the fixed plate 202. The push plate 209 is fixedly connected to the shock-absorbing plate 207 on the side of the door lock structure 3 located on the outside of the fixed plate 202. Rubber sleeves 204 are sleeved on both sides of the lock ring 201. The fixed plate 202 is fixedly provided with a sliding groove 206. The two sliding grooves 206 are slidably connected to the sliders 208. The two sliders 208 are fixedly connected to the support plate 210 on the side of the fixed plate 202 located on the outside of the fixed plate 202. The support plate 210 is fixedly connected to the side of the door lock structure 3 on the outside of the push plate 209.

[0024] Specifically, the fixing plate 202 is located on the door frame 1, and the latch ring 201 above it contacts the door lock structure 3 when the door is closed. The latch ring 201 is used to engage the door lock structure 3, which includes a handle, latch teeth, a locking plate, a steel wire, and a spring. When the upper and lower latch teeth contact the latch ring 201, they rotate, fixing their notches to the latch ring 201. The locking plate behind it is then engaged with the latch ring 201 within the notches of the latch teeth, thus locking the door. When the door needs to be opened, pulling the handle tilts the locking plate, which, under the action of the spring, springs back out of the notches of the latch teeth, thus releasing the door from its locked state. This technology is a mature existing technology, and its principles will not be described in detail here. When the door lock structure 3 contacts the strike ring 201, it touches the shock-absorbing plate 207 located outside the push plate 209. The shock-absorbing plate 207 is made of rubber and can effectively absorb the impact force generated when the door lock structure 3 is impacted. Afterwards, the push plate 209 will move backward due to the impact of the door lock structure 3. Since the push plate 209 passes through the moving hole 205 on the fixed plate 202 and enters the inner box 211 to connect with the four spring dampers 212, the four spring dampers 212 will be compressed accordingly. The push plate 209 will move backward within the moving hole 205. The spring dampers 212 absorb a large amount of impact force and reduce the vibration generated during the impact. The support plate 210 effectively supports the outer portion of the push plate 209, resulting in more even force distribution. The slider 208 on the support plate 210 moves within the groove 206 on the fixed plate 202. The groove 206 limits the movement of the support plate 210 and push plate 209 during the compression of the spring damper 212. The rubber sleeve 204 protects the strike ring 201, preventing direct contact with the door lock structure 3, reducing friction and impact, preventing deformation of the strike ring 201 due to impact, and minimizing scratches.

[0025] Reference Figure 1 , Figure 3 , Figure 5 The four corners of the fixing plate 202 are fixedly provided with threaded holes 203, and screws 213 are fixedly provided on the four threaded holes 203. The four screws 213 pass through the threaded holes 203 and are threadedly connected to the door frame 1. The inner box 211 is located inside the door frame 1.

[0026] Specifically, the interior of the door frame 1 is provided with a slot for placing the inner box 211. The inner box 211 is placed in the slot, and the fixing plate 202 is attached to the door frame 1. Then, the screws 213 are passed through the threaded holes 203 and tightened one by one to firmly fix it to the door frame 1. After that, it can be used normally.

[0027] Working principle: The inner box 211 is placed into the groove inside the door frame 1. Then, the fixing plate 202 is fitted into the door frame 1, the angle is adjusted, and four screws 213 are passed through the threaded holes 203 and tightened one by one to fix the fixing plate 202 to the door frame 1. After that, it can be used normally. When the door is closed, the door lock structure 3 inside the door will contact the latch ring 201 on the fixing plate 202, and the locking teeth on the door lock structure 3 will engage with the latch ring 201 for fixation. This process will generate an impact force. The rubber sleeve 204 provided on the latch ring 201 can protect the latch ring 201, so that it will not directly contact the door lock structure 3 during the contact process, reducing its friction and impact force, preventing the latch ring 201 from being deformed due to impact, and reducing scratches. Furthermore, the door lock structure 3 will impact the shock-absorbing plate 207 located outside the push plate 209. The shock-absorbing plate 207 is a rubber plate, which can effectively absorb the impact force generated when the door lock structure 3 impacts. Afterwards, the push plate 209 will retract under the impact of the door lock structure 3. Because the lower half of the push plate 209 passes through the moving hole 205 on the fixed plate 202 and enters the inner box 211 to connect with the four spring dampers 212, the four spring dampers 212 will compress and deform, absorbing the impact force generated during the impact and effectively reducing vibration, so that the push plate 209 retracts inside the moving hole 205. In addition, a support plate 210 is provided on the push plate 209, which is connected to the upper end of the push plate 209, so that the slider 208 above it can move on the slide groove 206 as the push plate 209 moves, which has a limiting effect on the push plate 209. At the same time, the upper half of the push plate 209 provides support and makes the force evenly distributed, improving its service life. The above operations can effectively mitigate the impact force generated when the door lock structure 3 collides with the latch ring 201, improve the safety of the door lock switch, and extend its service life.

[0028] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
