Description

Technical Field

[0001] This utility model relates to the field of automotive central locking technology based on improved connection methods, specifically an automotive central locking system based on improved connection methods. Background Technology

[0002] The core function of central locking systems in automobiles is to centrally control the locking and unlocking of all vehicle doors, thereby improving ease of use and vehicle security.

[0003] For example, a type of automotive central locking system with announcement number "CN112144992B" uses screws to tighten the housing, causing a fixing block to fit tightly against the lower end face of the housing, facilitating the disassembly and assembly of the mounting base for maintenance and replacement of the internal motor. The design of the heat dissipation holes can expel the heat generated by the motor, improving its service life. The locking block secures the locking slot, and the threaded sleeve is tightened, facilitating the disassembly and assembly of the housing. The design of the limit ring can restrict and fix the threaded sleeve to prevent it from rotating automatically and affecting the stability of the housing installation. However, in the use of automotive central locking systems, although the heat dissipation holes of the mounting base can expel the motor heat, it is an open design that "connects to the inside of the mounting base" without a dust screen or filter structure. During vehicle operation, road dust, mud, insect carcasses, and other impurities can easily enter the inside of the mounting base through the heat dissipation holes. Long-term accumulation may cover the motor surface, hindering heat dissipation and causing the internal motor of the automotive central locking system to disconnect. At the same time, the entire automotive central locking system needs to be disassembled for cleaning. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of a broken motor inside a car's central locking system, which requires the entire central locking system to be disassembled for cleaning. Therefore, this utility model proposes a car central locking system based on an improved connection method.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design an improved automotive central locking system based on a connection method, comprising a straight plate and a vertical rod. The top of the straight plate is fixedly connected to the bottom of the vertical rod. The outer wall of the vertical rod is connected to a protective structure. The rear end face of the straight plate is fixedly connected to the automotive central locking system. The front and rear sides of the automotive central locking system are respectively machined with slots, and the inner wall of the slots is connected to a shielding structure.

[0006] This setting: The central locking system of a car uses a combination of electronic control and mechanical execution to achieve centralized locking and unlocking of all doors. The core can be divided into "command input - signal processing - execution action".

[0007] Preferably, the protective structure includes a bracket and a mesh plate. The inner wall of the bracket is rotatably connected to the outer wall of the vertical rod. The right side of the bracket is fixedly connected to the left side of the mesh plate. A curved plate is fixedly connected to the right side of the mesh plate. A screw is threadedly connected to the inner wall of the curved plate. A first protective pad is fixedly connected to the outer wall of the mesh plate.

[0008] This feature: The mesh panel is made of stainless steel, which acts as a barrier against dust, mud, and insect carcasses, preventing them from entering the car's central locking system through the vents.

[0009] Preferably, the outer wall of the first protective pad is in contact with the front of the car's central locking system, and the rear of the outer wall of the screw is threaded to the front of the car's central locking system.

[0010] This feature: The end of the screw has a protruding ridge, which can form a force point with the hand, allowing the screw to be rotated back and forth through the curved plate without tools.

[0011] Preferably, a circular ring is fixed to the rear of the outer wall of the central locking system of the vehicle.

[0012] This feature: The outer wall of the ring is machined with multiple threaded openings, which facilitates the bolt threads to pass through the ring and be fixed to the car's connection port.

[0013] Preferably, a second protective pad is fixed to the outer wall of the ring.

[0014] This feature: The second pad is made of fluororubber and acts as a pad between the ring and the car mounting surface to prevent the ring from causing wear and tear on the car.

[0015] Preferably, the shielding structure includes a concave plate and a curved plate, the outer wall of the concave plate is slidably connected to the inner wall of the groove, the left side of the concave plate is fixedly connected to the right side of the curved plate, and an inner core is fixedly connected to the inner wall of the curved plate.

[0016] This feature: The inner core is made of carbon fiber to ensure the strength of the bending plate while greatly reducing its weight and preventing it from bending downwards.

[0017] Preferably, the outer wall of the curved plate is fitted to the bottom of the power interface of the car's central locking system, and the outer wall of the concave plate is connected to the inner wall of the groove by bolts and threaded connections.

[0018] This setting: The bolts serve to fix the concave plate and the groove, preventing the concave plate from sliding further on the inner wall of the groove.

[0019] This utility model proposes an improved automotive central locking system based on a connection method. The advantages are as follows: The protective mesh panel in the structure blocks the heat dissipation vents, preventing dust, mud, insect remains, and other impurities from entering. During cleaning, the hand holds the ridge plate at the end of the screw, and rotating the ridge plate causes the screw to rotate forward through the curved plate, disengaging the rear of the screw's outer wall from the circular opening on the front of the central locking system. Next, the bracket rotates forward through the outer wall of the vertical rod, causing the mesh panel to rotate forward and disengage from the heat dissipation vent on the front of the central locking system. The surface of the mesh panel is then cleaned. After cleaning, the mesh panel is flipped backward, pressing the first protective pad on the outer wall of the mesh panel against the front of the central locking system. Then, the bolt, with its right front-to-back thread, passes through the curved plate and connects with the threaded opening on the front of the central locking system, completing the mesh panel's fixation. This prevents the internal motor of the central locking system from breaking down, allowing for cleaning without the need for complete disassembly of the central locking system.

[0022] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-5In this embodiment, an improved automotive central locking system includes a straight plate 1 and a vertical rod 4. The top of the straight plate 1 is fixedly connected to the bottom of the vertical rod 4. A protective structure 2 is connected to the outer wall of the vertical rod 4. An automotive central locking system 5 is fixedly connected to the rear end face of the straight plate 1. The automotive central locking system 5 achieves centralized locking and unlocking of all vehicle doors through the coordinated cooperation of electronic control and mechanical execution. The core can be divided into "command input - signal processing - execution action". The front and rear sides of the automotive central locking system 5 are respectively machined with slots 6, and the inner wall of the slots 6 is connected to a shielding structure 3.

[0023] The protective structure 2 includes a bracket 201 and a mesh plate 202. The inner wall of the bracket 201 is rotatably connected to the outer wall of the vertical rod 4. The bracket 201 rotates under force through a bearing on the outer wall of the vertical rod 4. The right side of the bracket 201 is fixedly connected to the left side of the mesh plate 202. A curved plate 203 is fixedly connected to the right side of the mesh plate 202. The mesh plate 203 is made of stainless steel and serves to block dust, mud, and insect remains, preventing them from entering the interior of the car's central locking system 5 through the heat dissipation vents. A screw 204 is threadedly connected to the inner wall of the curved plate 203. A first protective pad 205 is fixed to the outer wall. The outer wall of the first protective pad 205 is in contact with the front of the car central door lock 5. The first protective pad 205 is made of fluororubber and plays a sealing role between the mesh plate 202 and the car central door lock 5. It also has good corrosion resistance and oxidation resistance. The rear of the outer wall of the screw 204 is connected to the round thread on the front of the car central door lock 5. The end of the screw 204 is provided with a protrusion. The protrusion can form a force point with the hand, so that the screw 204 can be rotated back and forth through the curved plate 203 without tools. The heat dissipation vents are blocked by the mesh plate 202 in the protective structure 2 to prevent dust, mud, insect remains, and other impurities from entering. During cleaning, the screw is held by the ridge plate at the end, and the screw 204 is rotated forward via the curved plate 203 by rotating the ridge plate. This causes the rear of the outer wall of the screw 204 to disengage from the round opening on the front of the central locking door lock 5. Next, the bracket 201 rotates forward via the outer wall of the vertical rod 4, causing the mesh plate 202 to rotate forward and disengage from the heat dissipation vent on the front of the central locking door lock 5. The surface of the mesh plate 202 is then cleaned. After cleaning, the mesh plate 202 is flipped backward, pressing the first protective pad 205 on the outer wall of the mesh plate 202 against the front of the central locking door lock 5. Then, the bolt, threaded from right front to back, passes through the curved plate 203 and connects to the threaded opening on the front of the central locking door lock 5, thus fixing the mesh plate 202 and preventing the internal motor of the central locking door lock from breaking down. Cleaning can be performed without disassembling the entire central locking door lock.

[0024] A circular ring 7 is fixedly attached to the rear of the outer wall of the central locking door 5. The outer wall of the circular ring 7 has multiple threaded openings, facilitating bolt threading through the ring and fixing it to the car's connection port. A second protective gasket 8, made of fluororubber, is fixedly attached to the outer wall of the circular ring 7, providing protection between the ring 7 and the car's mounting surface and preventing wear on the car. The shielding structure 3 includes a concave plate 301 and a curved plate 302. The outer wall of the concave plate 301 is slidably connected to the inner wall of the groove 6. The concave plate 301 slides left and right along the inner wall of the groove 6 under force. The left side is fixedly connected to the right side of the curved plate 302. The inner wall of the curved plate 302 is fixedly connected to the inner core 303. The inner core 303 is made of carbon fiber to ensure the strength of the curved plate 302 while greatly reducing the weight of the curved plate 302 and preventing the curved plate 302 from bending downwards. The outer wall of the curved plate 302 is in contact with the bottom of the power interface of the car central locking door 5. The outer wall of the concave plate 301 is connected to the inner wall of the groove 6 by bolts with round thread. The bolts play a fixing role between the concave plate 301 and the groove 6, so that the concave plate 301 cannot continue to slide on the inner wall of the groove 6.

[0025] Working principle: Car central locking system installation: Connect the rear shaft of the central locking system 5 to the car lock lever. At this time, the ring 7 on the outer wall of the central locking system 5 will press the second protective pad 8 onto the car's mounting surface. Then, the bolt, with its right front to rear thread, passes through the round opening on the outer wall of the ring 7 and connects with the round thread on the car's mounting surface. Next, the bolt rotates outward through the concave plate 301, causing the inner side of the bolt's outer wall to disengage from the round opening on the inner wall of the slot 6. Then, push the concave plate 301 to the right, causing it to move to the right in the slot 6. The moving concave plate 301, along with the bent plate 302, moves to the right. The moving bent plate 302 disengages from the power interface below the central locking system 5. Subsequently, the bolt thread passes through the concave plate 301 and connects with the corresponding slot thread on the inner wall of the slot 6, completing the fixation of the concave plate 301 and the bent plate 302. Finally, connect the car's power cord connector to the power interface at the bottom of the central locking system 5 to complete the installation of the central locking system 5.

[0026] Using car central locking systems: When the user presses the "unlock" button on the remote key, the key emits a radio signal at a specific frequency. The receiving antenna on the vehicle captures the signal and transmits it to the control unit (ECU). The ECU verifies the signal's validity and, upon confirmation, determines the current state and generates an "unlock" command. The ECU sends electrical signals to the actuators of all doors, causing the micro-motor shaft inside the actuator of the central locking system 5 to rotate. This rotation drives the lock block inside the lock to retract the latch, completing the unlocking action. At this time, the heat dissipation vents on the front of the central locking system 5 can expel the heat generated by the internal motor. Simultaneously, the mesh plate 202 blocks the vents to prevent dust, mud, insect remains, and other impurities from entering. The user then holds the ridge plate at the end of the screw and rotates it, causing the screw 204 to rotate forward via the curved plate 203, disengaging the rear of the screw 204 from the central locking system. The round opening on the front of the lock 5 is then used to rotate the bracket 201 forward through the outer wall of the vertical rod 4. The rotating bracket 201, along with the mesh plate 202, rotates forward and disengages from the heat dissipation vent on the front of the car central locking door lock 5. The surface of the mesh plate 202 is then cleaned. After that, the mesh plate 202 is flipped backward so that the first protective pad 205 on the outer wall of the mesh plate 202 is pressed tightly against the front of the car central locking door lock 5. Then, the bolt, with its right front to rear thread, passes through the curved plate 203 and connects with the threaded round opening on the front of the car central locking door lock 5, thus completing the fixation of the mesh plate 202. Cleaning and maintenance can be completed without disassembling the entire car central locking door lock 5.
