[0001] The present invention relates to the technical field of automobile accessories, and more specifically to an armrest cover plate arranged on an automobile armrest box. Background Art

[0002] At present, the car interior armrest box belongs to the car interior system, which is arranged behind the auxiliary instrument panel in the car cockpit. The armrest box is installed in the middle channel and connected to the auxiliary instrument panel. It is mainly used to beautify the interior, reflect ergonomics, and provide more sufficient storage space. The current armrest box has its own storage area, and drivers usually place some tea cups, mobile phones and other items.

[0003] The armrest box cover is set on the armrest box, and is used to close the opening of the armrest box. The armrest box cover needs to cooperate with locking pieces to lock it in the open position and the closed position to prevent it from sliding after being fixed in the above position. The locking pieces of the existing armrest covers are currently set in the slide grooves in the armrest cover body. The armrest cover body is a plastic part, which is easy to deform and difficult to control in size, which can easily lead to poor batch stability of the sliding opening force and the closing force, and is also difficult to use on new parts.

[0004] Based on the above reasons, it is necessary to improve the existing technology. Summary of the invention

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figures 1 to 7 A armrest box cover comprises an armrest cover hinge bracket 2 and a cover mechanism 4 rotatably arranged on the armrest cover hinge bracket 2, two groups of torsion spring seats 20 are arranged at intervals on the upper end of the armrest cover hinge bracket 2, a torsion spring sleeve 30 is arranged in the torsion spring seat, a torsion spring 3 is arranged outside the torsion spring sleeve 30, and also includes a rotating shaft 31, the rotating shaft 31 passes through the two torsion spring sleeves 30 and is fixed to the torsion spring sleeves 30.

[0017] The cover mechanism 4 includes a cover seat 40 and a cover body 41 that is slidably matched with the cover seat 40. Specifically, two first sliders 40a are arranged at intervals on one side of the cover seat 40, and two second sliders 40b are arranged at intervals on the other side of the cover seat. The first slider 40a is arranged at a height higher than the second slider 40b. A first slide groove 41a is arranged on the inner wall of one side of the cover body 41, and a second slide groove 41b is arranged on the inner wall of the other side of the cover body. A guide groove 410 opening downward is arranged on the second slide groove 41b. The first slider is located in the first slide groove, and the second slider is located in the second slide groove. When the cover body and the cover seat are matched and installed, the above structure can first buckle the first slider into the first slide groove, then move the cover body so that the second slider is aligned with the guide groove, and then slide the second slider into the slide groove along the guide groove. At this time, the assembly between the cover seat and the cover body is completed. The above structure greatly improves the installation efficiency and installation accuracy.

[0018] One end 3a of the torsion spring 3 is fixed in a fixing hole provided in the torsion spring seat, and the other end 3b of the torsion spring 3 is fixed to the cover seat 40, that is, when the cover body is opened, the torsion spring stores potential energy so that the cover seat has a tendency to rotate toward the opening direction of the box body.

[0019] A handrail slide rail 1 is fixedly arranged in the cover plate seat 40, and a guide rail slider 5 is fixedly arranged in the cover plate body 41. The guide rail slider 5 is slidably matched with the handrail slide rail 1. Limiting columns 10 are respectively arranged at the front and rear ends of the handrail slide rail 1, and a fork member 6 is fixedly arranged in the cover plate body 41. Fork heads 60 are arranged at both ends of the fork member, and the fork head 60 and the limiting columns 10 match in shape; when the cover plate body 41 slides toward the rear end along the cover plate seat 40 until the cover plate body completely closes the box body, the fork head 60 located at the rear end of the fork member 6 is buckled on the limiting column at the rear end of the slide rail to achieve the locking of the cover plate body at this position. At this time, a certain force can be applied to the cover plate body to make the fork head disengage from the limiting column; when the cover plate body slides to the front end to the limit position, the fork head located at the front end of the fork member is buckled on the limiting column at the front end of the slide rail to achieve the locking of the cover plate body at this position.

[0020] The fork head 60 includes a trumpet-shaped opening 60a, a limiting hole 60b connected to the opening 60a, and a strip hole 60c provided on one side of the limiting hole 60b. The limiting post 10 can enter the limiting hole 60b and be limited after being guided along the opening 60a, and the plastic deformation of the two sides of the limiting hole 60b provides a force to limit the limiting post 10. The provision of the strip hole 60c can facilitate the two sides of the limiting hole to be better opened when the limiting post 10 slides along the opening 60a.

[0021] The locking mechanism (i.e., the fork piece) of the handrail slide rail in the present application is a separately made plastic part, which is installed on the upper cover fixing block and then installed as a whole on the slide rail assembly. The movement distance of the slide rail is then locked by using the limit columns at both ends of the slide rail assembly. The limit columns can be adjusted according to the actual sliding requirements of the handrail without the need to redevelop the mold, which effectively reduces the cost.

[0022] The present invention can realize a locking device for the sliding of the same type of central channel armrest. It only needs to change the position of the limit column on the slide rail group to ensure the center distance of the limit position with the locking mechanism, without the need for complete redevelopment.

[0023] The above shows and describes the basic principle, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments. The above embodiments and descriptions in this application are only the principles of the present invention, and the present invention may have various changes and modifications without departing from the spirit and scope of the present invention. The above changes and modifications all fall within the scope of the present invention claimed.
