Description

Technical Field

[0001] This utility model relates to the field of automotive armrests, and in particular to an armrest hinge structure for automobiles. Background Technology

[0002] Originally designed to provide elbow support for passengers, modern car armrests have evolved to include storage functions such as cup holders and storage boxes in addition to providing support.

[0003] To facilitate passenger access to and from their seats, car handrails are typically installed using hinges. This allows the handrails to rotate to either a horizontal or vertical position. When the handrail is horizontal, passengers can easily use it; when it is vertical, passengers can easily get in and out of their seats.

[0004] Existing automotive armrest hinges typically consist of a fixed bracket, a connecting plate, and a pin. A rotation-limiting latch is installed between the connecting plate and the fixed bracket. When the connecting plate rotates the armrest to a horizontal position, the latch engages and limits the connection, ensuring the stability of the connection and armrest in a horizontal state. However, the latch on the connecting plate is usually located near the pin. According to the lever principle, when the connecting plate is subjected to force, the compressive torque on the latch increases, leading to deformation and damage. Furthermore, since the latch is integrated with the connecting plate, damage to the latch necessitates replacement of the entire hinge, thus presenting a certain defect. Utility Model Content

[0030] 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.

[0031] This utility model provides, for example Figure 1-3 The illustrated automotive armrest hinge structure includes a fixed bracket 1, a mounting component 3, and a connecting shaft 2. The connecting shaft 2 is fixedly mounted on the top of the fixed bracket 1. The mounting component 3 is rotatably connected to the outside of the connecting shaft 2. The armrest can be mounted on the mounting component 3 using screws, allowing the armrest to rotate relative to the fixed bracket 1 via the mounting component 3 and the connecting shaft 2. The fixed bracket 1 contains a limiting component 4 that supports and limits the mounting component 3. The limiting component 4 includes a mounting housing 41, a locking component 42, a support component 43, and a triangular block 44. The mounting housing 41 is secured by the locking component... The component 42 is installed inside the fixed bracket 1, the support component 43 is fixedly connected to the top of the mounting housing 41, the top of the support component 43 fits against the mounting component 3, and the triangular block 44 is fixedly connected between the support component 43 and the mounting housing 41. The triangular block 44 can improve the stability of the support component 43 installed on the top of the mounting housing 41, so that the support component 43 is in a stable state to support the mounting component 3, and the mounting component 3 is in a stable horizontal state. When the locking component 42 is released from the locking state of the mounting housing 41, the support component 43 can be disassembled and replaced.

[0032] In particular, the locking assembly 42 includes a docking plate 421, a connecting plate 423, and a positioning plate 422. The bottoms of the two docking plates 421 are fixedly connected to the fixed bracket 1. The positioning plate 422 is fixedly connected to the bottom of the connecting plate 423 on the side facing the docking plate 421. The connecting plate 423 is slidably disposed inside the mounting housing 41. The docking plate 421 is engaged with the mounting housing 41 through the positioning plate 422. The bottom of the mounting housing 41 has symmetrically opened connecting holes. The outer wall of the docking plate 421 is slidably engaged with the inner cavity of the connecting hole. A positioning hole is opened on one side of the docking plate 421. The outer wall of the positioning plate 422 is slidably engaged with the inner cavity of the positioning hole. Thus, the two positioning plates 422 on the opposite side of the two connecting plates 423 are engaged with the two docking plates 421, which can ensure the stability of the mounting housing 41 installed on the fixed bracket 1.

[0033] Furthermore, the locking assembly 42 also includes a guide rod 424 and a limiting spring 425. The guide rod 424 is fixedly connected to the inside of the mounting housing 41. The outer wall of the guide rod 424 is slidably inserted into the connecting plate 423. The limiting spring 425 is slidably sleeved on the outside of the guide rod 424. The limiting spring 425 is located on the side of the connecting plate 423 away from the positioning plate 422, that is, the limiting spring 425 is located between the two connecting plates 423, so that the two connecting plates 423 drive the two positioning plates 422 to maintain a stable locking state with the docking plate 421.

[0034] Furthermore, the locking assembly 42 also includes a connecting rope 426, a winding shaft 427, and a fixing member 428. One end of the connecting rope 426 is fixedly connected to the connecting plate 423. The winding shaft 427 is rotatably mounted on the top of the inner cavity of the mounting housing 41. The other end of the connecting rope 426 is fixedly connected to the winding shaft 427 via the fixing member 428. One end of the winding shaft 427 passes through the mounting housing 41 and is fixedly connected to a handle. The interior of the mounting housing 41 is symmetrically provided with guide shafts 4210 for guiding the connecting rope 426. A fixing block 429 is fixedly connected to the end of the shaft 4210. The bottom of the fixing block 429 is fixedly connected to the mounting housing 41. Under the action of the two guide shafts 4210, the winding shaft 427 is rotated by the handle to wind up the two connecting ropes 426. This causes the two connecting plates 423 to drive the two positioning plates 422 to move relative to each other, so that the positioning plates 422 are separated from the docking plates 421. This releases the locking state of the mounting housing 41, thereby allowing the mounting housing 41 and the support member 43 to be disassembled.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
