Abstract
Description
Technical Field
[0001] This utility model relates to the field of headrest rod technology, specifically an anti-shaking headrest rod. Background Technology
[0002] Headrest bars are an important component of car seats, primarily used to support the head and provide comfortable support. Existing automotive headrest bars provide support by inserting into the foam inside the headrest. However, the headrest bar has a simple U-shaped bend structure with little distance between the foam covering and the bar itself. Even slight force applied to the headrest foam can cause it to loosen and wobble. Therefore, a headrest bar that overcomes these technical shortcomings is needed to improve usability. Utility Model Content
[0003] The purpose of this utility model is to provide an anti-shaking headrest rod to solve the problem mentioned in the background art. In actual use, the existing automotive headrest rod provides support by being inserted into the foam inside the headrest. However, the headrest rod has a simple U-shaped bending structure, and the distance between the foam covering and the rod body is small. The problem is that the headrest foam will loosen and shake when applied with slight force.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model is an anti-shake headrest rod, comprising:
[0006] The headrest rod module includes a rod body. A reinforcing steel is attached to the upper end of the inner wall of the rod body, and locking posts are threaded through the lower parts of both sides of the reinforcing steel and extend to the opposite sides of the upper end of the inner wall of the rod body. The end of the locking post is threaded with a locking nut and abuts against the inner and outer sides of the lower part of the reinforcing steel.
[0007] Furthermore, the reinforcing steel includes a movable frame, a movable cavity is formed through the middle of the movable frame, and a movable steel is movably disposed within the movable cavity.
[0008] Furthermore, the movable frame and the lower part of the movable steel are provided with threaded holes on the inner and outer sides, which extend into the rod body, and the inner wall of the threaded hole is threaded with the locking pin.
[0009] Furthermore, it also includes a docking module, which includes a docking interface and docking posts. The docking interface is located in the center of the lower end of the rod, and the ends of the docking posts are respectively sleeved on the inner wall of the docking interface.
[0010] Furthermore, the docking module also includes a threaded cavity, which is opened through the center of the upper end of the rod.
[0011] Furthermore, the lower part of the outer surface of the rod is provided with anti-slip textures at equal intervals.
[0012] This utility model has the following beneficial effects:
[0013] This invention features a reinforcing steel reinforcement attached to the upper end of the inner wall of the headrest. This reinforcement increases the contact distance between the headrest and the foam, reduces frictional resistance, and ensures the stability of the headrest structure, thereby preventing the headrest from shaking and improving its usability. Furthermore, the movable frame and the movable connections between the reinforcing steel reinforcement allow for angle adjustment. When there is less foam in the headrest, the angle can be adjusted to create resistance between the headrest and the foam, enhancing the structural applicability and functionality to meet specific needs.
[0014] Based on the aforementioned beneficial effects, in actual use, the pole provides head support while its lower end has an interface for connecting with the connecting post. This allows two poles to be connected and fixed together to form a material storage structure. The anti-slip texture on the surface can accommodate multiple disassembled poles for material storage, further enhancing the applicability and functionality of the structure.

[0022] 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.
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0024] Please see Figure 1-4 As shown, this utility model is an anti-shake headrest rod, comprising:
[0025] The headrest rod module includes a rod body 11. A reinforcing steel 12 is attached to the upper end of the inner wall of the rod body 11, and locking pins 13 are threaded through the lower parts of both sides of the reinforcing steel 12 and extend to the opposite sides of the upper end of the inner wall of the rod body 11. The end of the locking pin 13 is threaded with a locking nut 14, which abuts against the inner and outer sides of the lower part of the reinforcing steel 12.
[0026] The rod 11 provides support for the human head, and the reinforcing steel 12 increases the contact friction and contact distance between the rod 11 and the headrest foam, ensuring that the headrest does not wobble under force and improving the use effect. The locking column 13, together with the locking nut 14, locks the reinforcing steel 12 structurally and meets the requirements for angle adjustment.
[0027] The reinforcing steel 12 includes a movable frame 121, a movable cavity 122 is provided through the middle of the movable frame 121, and a movable steel 123 is movably arranged in the movable cavity 122;
[0028] The movable frame 121, together with the movable cavity 122, supports the movable steel 123. The movable space provided by the movable cavity 122 can meet the angle conversion and adjustment of the movable steel 123 to form an angle difference, which can provide reasonable support when the headrest foam is less.
[0029] The movable frame 121 and the movable steel 123 have threaded holes on their inner and outer sides at the bottom, which extend into the rod 11, and the inner wall of the threaded hole is threaded with the locking post 13.
[0030] The threaded hole receives the aforementioned locking pin 13.
[0031] Working principle: During the use of the rod 11, the locking pin 13 and locking nut 14 are used to structurally limit the reinforcing steel 12, so that the reinforcing steel 12 is fixed to the upper end of the inner wall of the rod 11. The reinforcing steel 12 increases the contact friction damping and contact distance between the rod 11 and the headrest foam. If there is less headrest foam, force can be applied to the movable steel 123, and the appropriate angle can be adjusted under the rotation of the thread to make the movable steel 123 frame with the angle difference and the movable steel 123 abut against the headrest foam.
[0032] This design prevents the headrest from shaking, improves usability, and makes it suitable for various environments, thus enhancing structural functionality.
[0033] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment and also includes a docking module. The docking module includes a docking interface 21 and a docking post 22. The docking interface 21 is opened in the center of the lower end of the rod 11, and the ends of the docking posts 22 are respectively sleeved with the inner wall of the docking interface 21.
[0034] The lower part of the outer surface of the rod 11 is provided with anti-slip textures at equal intervals;
[0035] The fitting of the end of the docking post 22 with the inner wall of the docking interface 21 can fix a group of connected rods 11 to form a material placement structure for storing multiple disassembled rods 11. The anti-slip texture increases the contact friction and ensures the stability of the material placement structure.
[0036] The docking module also includes a screw cavity 23, which is opened through the center of the upper end of the rod 11;
[0037] The screw cavity 23, in conjunction with the external bolts, can define the material placement structure formed by the aforementioned set of rods 11.
[0038] Working principle: After disassembling the rod 11, if the number of disassembled rods 11 gradually increases, the connecting column 22 can be used in conjunction with the interface 21 to install and limit a group of connected rods 11 to form a material placement structure. Then, the remaining rods 11 can be placed on the upper end of the material placement structure.
[0039] This solution allows for the storage and placement of multiple disassembled rods 11, further enhancing the applicability and functionality of the structure.
