Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Such as Figures 1 to 8As shown in the figure, the utility model provides an automotive ceiling folding armrest, which includes a fixing part 5 and two connecting parts 1. A glove cover 2 is sleeved on the fixing part 5, and the bottom end of the glove cover 2 is open, enabling the glove cover 2 to be directly sleeved on the surface of the fixing part 5 from top to bottom. Moreover, the glove cover 2 is made of elastic material, so that when the bottom end of the glove cover 2 is pressed against the top end of the fixing part 5, it will expand to both sides until it is completely sleeved on the fixing part 5. At this time, the bottom ends of the glove cover 2 will approach each other. Two positioning mechanisms are provided at the bottom end of the glove cover 2, which include two bottom grooves 4 opened at the bottom end of the glove cover 2. Through grooves 41 are opened on the inner walls of both bottom grooves 4. A rotating cylinder 43 is rotatably connected to the inner top wall of one of the bottom grooves 4. A rotating rod 44 is rotatably connected to the middle of the rotating cylinder 43. One end of the rotating rod 44 passes through both through grooves 41 and is fixedly connected with a positioning plate 42, and the surface of the positioning plate 42 is in contact with the inner wall of the other bottom groove 4. With the above structure, it is convenient to fix the sleeved glove cover 2, and no other auxiliary tools are required. The overall disassembly and assembly operation is simple and convenient, and it does not occupy much space, ensuring the normal use of personnel. During specific operation, just swing the rotating rod 44 to slide the positioning plate 42 into the bottom groove 4 on the other side, and then rotate the rotating rod 44 to drive the positioning plate 42 to be vertical, effectively preventing the subsequent accidental rotation of the rotating rod 44, thus ensuring the connection stability of the bottom end of the glove cover 2 and preventing the glove cover 2 from falling off the fixing part 5. Moreover, when a person holds the glove cover 2, the person's fingers are above the glove cover 2, so the installation stability of the glove cover 2 is further ensured.

[0026] As Figure 3 and Figure 5 shown in the figure, guide holes 8 and two slots 9 are opened at both the left and right ends of the glove cover 2, and the two slots 9 are located at the bottom end of the glove cover 2. Installation grooves 11 are opened inside both connecting parts 1, and a locking mechanism for inserting the guide holes 8 and the two slots 9 is provided in each installation groove 11. Through the locking mechanism, after the glove cover 2 is sleeved on the fixing part 5, it can be inserted into the guide holes 8 and the two slots 9 through the locking mechanism, thus ensuring the stability of the sleeved glove cover 2.

[0027] As Figures 4 to 6As shown in the figure, the locking mechanism includes a moving plate 16 and a fixed plate 14. The moving plate 16 is elastically slidably arranged in the installation groove 11. The fixed plate 14 is fixedly connected to the inner wall of the installation groove 11. A pull rod 13 is fixedly connected to the middle of the moving plate 16. One end of the pull rod 13 penetrates through the fixed plate 14 and is rotatably connected to a swing rod 12. A guide rod 6 and two insertion rods 7 are fixedly connected to the moving plate 16. The guide rod 6 and the two insertion rods 7 are respectively inserted into corresponding guide holes 8 and two slots 9. With the above structure, when the glove holder 2 is installed, the two swing rods 12 are respectively pulled to move and positioned on the surface of the corresponding connecting part 1, so that the guide rod 6 and the insertion rods 7 are retracted into the installation groove 11. Then, the glove holder 2 can be normally sleeved on the fixing part 5 from top to bottom. After the sleeving is completed, the positioning of the swing rod 12 can be released, so that the moving plate 16 can drive the guide rod 6 and the insertion rods 7 to insert into the corresponding guide holes 8 and slots 9, thus ensuring the stability of the glove holder 2 and preventing it from falling off.

[0028] As Figure 1 , Figure 2 and Figure 5 shown, the inner walls of the two installation grooves 11 are both hinged with a cover plate 3, and the top end of the cover plate 3 is clamped on the surface of the connecting part 1. With the setting of the cover plate 3, the structure inside the installation groove 11 can be shielded and protected to prevent foreign objects from entering. And when a person operates the components in the installation groove 11, only need to turn the cover plate 3 downward.

[0029] As Figure 5 and Figure 6 shown, a compression spring 15 is fixedly connected between the fixed plate 14 and the moving plate 16, and the compression spring 15 is sleeved on the surface of the pull rod 13. The elastic force of the compression spring 15 can make the moving plate 16 closely adhere to the inner wall of the installation groove 11, further ensuring that the guide rod 6 and the insertion rods 7 can stably insert into the corresponding guide holes 8 and slots 9.

[0030] As Figure 3 shown, a plurality of holding grooves 10 are opened at the top end of the glove holder 2. With the setting of the holding grooves 10, it is convenient for a person's fingers to hold the glove holder 2, thus ensuring the anti-slip property of the person's holding.

[0031] Working principle and usage process of the present utility model: When installing the handrail sleeve 2, first pull the two swing rods 12 to move respectively and position them on the surface of the corresponding connecting part 1, so that the guide rod 6 and the insertion rod 7 are retracted into the installation groove 11. Then, the handrail sleeve 2 can be directly sleeved on the fixing part 5 from top to bottom normally. Next, release the positioning of the swing rod 12, so that the moving plate 16 can drive the guide rod 6 and the insertion rod 7 to insert into the corresponding guide holes 8 and slots 9, thereby ensuring the stability of the handrail sleeve 2 and preventing it from falling. Then, swing the rotating rod 44, slide the positioning plate 42 to the bottom groove 4 on the other side, and then rotate the rotating rod 44, which can drive the positioning plate 42 to be vertical, effectively preventing the subsequent accidental rotation of the rotating rod 44, further ensuring the connection stability at the bottom of the handrail sleeve 2 and preventing the handrail sleeve 2 from falling off the fixing part 5. Moreover, when a person holds the handrail sleeve 2, the person's fingers are above the handrail sleeve 2, so it further ensures the stable installation of the handrail sleeve 2.

[0032] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. The content not described in detail in the specification belongs to the prior art well-known to those of ordinary skill in the art.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
