Description

Technical Field

[0001] This utility model relates to the field of automotive armrest technology, and in particular to an armrest opening synchronization coordination mechanism. Background Technology

[0002] Currently, the armrest box lid has a two-part double-opening structure, with the left and right halves of the armrest opening to the sides. The opening space of the two halves of the armrest is relatively large, making it convenient for the driver and passenger to take out and put in items. However, in the existing armrest structure, the two halves of the armrest cannot open synchronously or nearly synchronously, making the opening operation not smooth.

[0003] For example, patent CN119408468A discloses a split-type armrest base for automobiles and its injection mold. The split-type armrest base for automobiles includes an armrest base and a pair of armrest covers. The armrest covers on each side are hinged together by a pivot on the armrest base. Each armrest cover needs to be opened separately and cannot be opened synchronously or nearly synchronously, making the opening operation cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a handrail opening synchronization and coordination mechanism, in which the handrails on both sides open in coordination, making the opening operation simple.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] The handrail opening synchronization coordination mechanism includes a handrail box base and a pair of handrails that can be opened relative to each other on the handrail box base. Each handrail is hinged to the corresponding side of the handrail box base via a corresponding pivot. The two pivots of the pair of handrails are connected by an opening synchronization coordinator. The ends of the pivots are connected to rotating arms. A pair of telescopic rods that extend and retract synchronously are provided on opposite sides of the opening synchronization coordinator. Each telescopic rod is connected to the rotating arm on the corresponding side via a linkage rod.

[0007] Further or preferred:

[0008] The handrail includes a handrail body and a skin on the handrail body, and the pivot is connected to the edge of the handrail body.

[0009] The opening synchronization coordinator is located at the rear of the armrest box base.

[0010] The telescopic rod has a waist-shaped hole at its end. The outer end of the connecting rod is hinged to the rotating arm. The inner end of the connecting rod has a movable pin located inside the waist-shaped hole.

[0011] The opening synchronization coordinator includes a coordinator housing and a gear disposed inside the coordinator housing. The inner ends of a pair of telescopic rods extend into the housing and mesh with the gear. The housing is fixed to the rear of the armrest box base.

[0012] The inner end of the telescopic rod is provided with a rack, and the gear is located between the inner ends of the two telescopic rods.

[0013] A spring is provided inside the housing corresponding to the inner end of each telescopic rod.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] The handrail opening synchronization coordination mechanism has a reasonable structural design. The two handrails are arranged opposite each other and connected by the opening synchronization coordinator at the rear. The two handrails can be opened synchronously and in coordination, making the opening operation simple and eliminating the need for separate opening operations. The synchronization coordinator is also integrated into the design, resulting in a compact structure. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0024] like Figures 1 to 4 As shown, the handrail opening synchronization coordination mechanism includes a handrail box base 1 and a pair of handrails 2 that can be opened relative to each other on the handrail box base. Each handrail is hinged to the corresponding side of the handrail box base via a corresponding pivot 7, and the pair of handrails can be opened relative to each other.

[0025] The two pivots of a pair of handrails are connected by an opening synchronization coordinator. The ends of the pivots are connected to rotating arms 6. A pair of telescopic rods 4 that extend and retract synchronously are provided on opposite sides of the opening synchronization coordinator. Each telescopic rod is connected to the rotating arm on the corresponding side through a linkage rod 5.

[0026] The handrail opening synchronization coordination mechanism of this utility model has a reasonable structural design. The handrails on both sides are arranged opposite each other and connected by the opening synchronization coordinator at the rear. The handrails on both sides can be opened synchronously and in coordination, making the opening operation simple and eliminating the need for separate opening operations.

[0027] The handrail includes a handrail body 201 and a skin on the handrail body 201. The pivot is connected to the edge of the handrail body. A rotating sleeve is provided at the rear of the handrail box base corresponding to the pivot. The pivot passes through the rotating sleeve, and the structure is stable and reliable.

[0028] The opening synchronization coordinator is located at the rear of the armrest box base 1; furthermore, the rear of the armrest box base is a vertical surface or a vertical groove structure, and the opening synchronization coordinator is integrated on the rear of the armrest box base, resulting in a compact structure.

[0029] The telescopic rod 4 has a waist-shaped hole at its end. The outer end of the connecting rod 5 is hinged to the rotating arm. The inner end of the connecting rod has a movable pin, which is located in the waist-shaped hole, ensuring stable and reliable operation.

[0030] The coordinator body 3, which activates the synchronization coordinator, includes a coordinator housing 301 and a gear 303 housed within the housing. The inner ends of a pair of telescopic rods extend into the housing and mesh with the gear. The housing is fixed to the rear of the armrest box base. Preferably, the inner ends of the telescopic rods are equipped with racks, and the gear is located between the inner ends of the two telescopic rods, thereby achieving synchronous extension and retraction of the two telescopic rods.

[0031] The coordinator housing is fixed to the rear of the armrest box base by a pair of screws located on both sides of the gear, ensuring stable and reliable fixation and a compact structure.

[0032] Each telescopic rod has a spring 302 inside the housing to coordinate the opening of the handrails on both sides; the spring is a compression spring, which holds the inner end of the telescopic rod against the spring force.

[0033] If one side of the handrail opens relatively quickly while the other side opens relatively slowly, and the spring on one side exerts a relatively large force against the inner end of the telescopic rod on that side, meaning that the handrail on one side has greater resistance to opening, and the spring on the other side exerts a relatively small force against the inner end of the telescopic rod on that side, meaning that the handrail on that side has less resistance to opening, then the handrails on both sides can be opened in a coordinated manner, almost synchronously.

[0034] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.

[0035] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
