Description

Technical Field

[0001] This utility model belongs to the field of automotive assembly technology and relates to a buffer structure for an automotive door limiter. Background Technology

[0002] A car door limiter is a mechanical device installed between the car door and the car body. Its core function is to precisely control the opening angle of the door and provide damping during the opening and closing process to prevent the door from moving excessively due to inertia or external force. Its main structure usually includes a limit arm, a housing, hydraulic and mechanical damping components, and a buffer block. For example, a design using a hydraulic cylinder and piston rod can be used. When the door approaches its maximum opening, the hydraulic oil or rubber damping ring generates resistance by compression, gradually reducing the door speed. The multi-stage grooves or protrusions on the limit arm achieve segmented positioning, ensuring that the door stops stably at different angles.

[0003] For example, patent (CN213774925U) discloses a door limiter with a buffer structure, which describes that it "includes a seat plate, a pull plate, a bracket, a limit box, and a buffer member. The seat plate has a through groove. One end of the pull plate is rotatably connected to the bracket. The other end of the pull plate passes through the through groove and is fixedly connected to the limit box. The seat plate is slidably disposed on the pull plate. The buffer member is disposed on the limit box and is located at the end of the limit box near the seat plate. By providing an integrally formed buffer member on the limit box and placing the buffer member on the side wall of the pull plate, when the door is pulled, the pull plate slides, thereby driving the limit box to move towards the seat plate. After the door is pulled to a certain position, the buffer member abuts against the seat plate. The buffer member can play a good buffering role and is not easily damaged by shear force."

[0004] When using the above technology, the following technical problems were found in the existing technology: During the use of the existing device, after a long period of use, the boss is severely worn due to repeated opening and closing actions, which makes it impossible for the boss to achieve the positioning and buffering effect. Currently, the workers replace the limiter buffer structure assembly to enable the door to continue to achieve the positioning and buffering effect when opening and closing. However, since one end of the limiter is installed inside the door, it is quite complicated for the workers to replace the limiter buffer structure. Utility Model Content

[0005] The technical problem this utility model aims to solve is that, in the use of existing devices, the boss wears out significantly after prolonged use due to repeated opening and closing actions, thus preventing the boss from achieving the positioning and buffering effects. Currently, workers replace the limiter buffer structure assembly to ensure that the door continues to achieve the positioning and buffering effects during opening and closing. However, since one end of the limiter is installed inside the door, replacing the limiter buffer structure is quite complicated.

[0006] The present invention discloses a car door limiter buffer structure, comprising a support member; a frame connector is mounted on one end of the support member; a door connector is mounted on the end of the support member away from the frame connector; a door connecting sliding member is provided on the outer side of the support member; multiple sets of limiting grooves are formed on the inner side of the support member; a boss is provided between every two corresponding limiting grooves; a limiting component is provided between the support member and the boss; and a clamping component is provided at the end of the support member.

[0007] The limiting component includes a limiting block, and both ends of the boss are fixedly connected to limiting blocks; the lower end of the limiting block is fixedly connected to limiting teeth; multiple sets of limiting tooth grooves are opened on the inner side of the support member; the limiting teeth and the limiting tooth grooves are slidably engaged.

[0008] The clamping assembly includes a pressing plate; two sets of pressing plates are provided at the end of the support member; a countersunk hole is provided in the middle of the end of the pressing plate away from the support member; and a threaded hole is provided in the middle of the support member.

[0009] Multiple sets of extrusion shaped blocks are fixedly connected to one end of the extrusion plate near the support member; the extrusion shaped blocks are slidably connected to the limiting groove.

[0010] The lower end of the extruded irregular block is fixedly connected with extrusion saw teeth; the extrusion saw teeth are slidably engaged with the limiting tooth groove.

[0011] The boss is made of silicon manganese steel with a thickness of 0.3mm.

[0012] Compared with the prior art, the beneficial effect of this utility model is that by replacing the boss, the staff can restore the positioning and buffering effect of the door when opening and closing without replacing the limiter buffer structure assembly, thereby reducing resource waste.

[0013] When the staff needs to replace the boss, they only need to open the door to its maximum angle, so that the door moves the door connecting sliding part to the end away from the frame connecting part, thereby fully exposing the extrusion plate. This allows the staff to replace the boss without disassembling the door. Attached Figure Description

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] Example 1

[0026] like Figure 1 - Figure 5 As shown, a car door limiter buffer structure includes a support member 101; a frame connector 102 is installed at one end of the support member 101; a door connector 103 is installed at the end of the support member 101 away from the frame connector 102; a door connecting sliding member 104 is provided on the outer side of the support member 101; multiple sets of limiting grooves 106 are formed on the inner side of the support member 101; a boss 105 is provided between every two corresponding limiting grooves 106; a limiting component is provided between the support member 101 and the boss 105; and a clamping component is provided at the end of the support member 101.

[0027] The limiting component includes a limiting block 201, and both ends of the boss 105 are fixedly connected to the limiting block 201; the lower end of the limiting block 201 is fixedly connected to the limiting tooth 202; multiple sets of limiting tooth grooves 203 are opened on the inner side of the support member 101; the limiting tooth 202 and the limiting tooth groove 203 are slidably engaged.

[0028] The boss 105 is made of silicon manganese steel with a thickness of 0.3mm.

[0029] During operation, when the boss 105 is severely worn, the boss 105 is moved, causing the boss 105 to slide out from the inside of the limiting block 201 and the limiting serration 202. Then, a new boss 105 is installed inside the limiting groove 106. During installation, the limiting serration 202 and the limiting tooth groove 203 are engaged with each other, so that when the boss 105 is deformed by the door connecting sliding member 104, it has better support to help the boss 105 return to its original shape. The limiting groove 106 also supports the boss 105. Thus, the operator does not need to replace the limiter buffer structure assembly. By replacing the boss 105, the positioning and buffering effect of the door during opening and closing can be restored, thereby reducing resource waste.

[0030] Example 2

[0031] like Figure 1 - Figure 5 As shown, the clamping assembly includes a pressing plate 301; two sets of pressing plates 301 are provided at the end of the support member 101; a countersunk hole 302 is provided in the middle of the end of the pressing plate 301 away from the support member 101; and a threaded hole 303 is provided in the middle of the support member 101.

[0032] Multiple sets of extrusion shaped blocks 401 are fixedly connected to one end of the extrusion plate 301 near the support member 101; the extrusion shaped blocks 401 are slidably connected to the limiting groove 106.

[0033] The lower end of the extruded irregular block 401 is fixedly connected with an extrusion saw tooth 501; the extrusion saw tooth 501 is slidably engaged with the limiting tooth groove 203.

[0034] During operation, after the boss 105 is replaced, the extrusion plate 301 is placed at the end of the support 101, causing the extrusion shaped block 401 to slide into the inner side of the limiting groove 106. Then, the operator places screws inside the countersunk hole 302 and the threaded hole 303, and rotates the screws to install the extrusion plate 301 and the support 101 together. The extrusion shaped block 401 and the extrusion serrations 501 then extrude force on the boss 105, the limiting block 201, and the limiting serrations 202, thereby restricting the boss. The position of the boss 105 when it deforms makes the boss 105 more stable in the deformed state. At the same time, since the extrusion plate 301 is located in the middle of the support member 101, when the staff needs to replace the boss 105, they only need to open the door to the maximum angle, so that the door drives the door connecting sliding member 104 to move to the end away from the frame connecting member 102, thereby fully exposing the extrusion plate 301. Thus, the staff can replace the boss 105 without disassembling the door.

[0035] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
