Technical Field
[0001] The invention relates to the technical field of headrest adjustment mechanisms, and in particular to a headrest adjustment mechanism for a multimedia golf cart. Background Art
[0002] Golf carts are mainly used in golf courses to help players move between holes quickly and conveniently, reduce walking distance, and improve playing efficiency. They usually have a small body and flexible steering performance to adapt to the complex terrain and narrow passages of the golf course.
[0003] Golf carts are usually equipped with two iron rods under the headrest, and there is a round plastic ring under each iron rod. The outer petal of the plastic ring on one side is designed to be pressable, and the passenger only needs to gently press the outer petal of the plastic ring on one side to adjust the height of the headrest.
[0004] However, the headrests of golf carts currently on the market often only support height adjustment, and cannot adjust the looseness of the headrest. The looseness of the headrest directly affects the user's comfort. A headrest that is too tight may cause unnecessary pressure on the neck, causing discomfort or even pain; while a headrest that is too loose may not provide sufficient support, which may also cause discomfort. Therefore, a headrest adjustment mechanism that can adjust the looseness of the headrest is urgently needed. Summary of the invention

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0028] Reference Figure 1-9 A multimedia golf cart headrest adjustment mechanism includes a back plate 1 and a headrest body 2. The back plate 1 is installed at the rear of the headrest body 2. Both sides of the back plate 1 are vertically fixed with a horizontal column 14. The horizontal column 14 is movably provided with a mounting plate 4, and both sides of the mounting plate 4 are fixedly connected to the headrest body 2. A groove 17 is provided at the rear of the back plate 1. A limit plate 3 is adapted to be installed in the groove 17. Both sides of the limit plate 3 are fixedly provided with a side plate 31 for clamping the mounting plate 4, and the limit plate 3 is guided and moved by a guide column 18. Through the movement of the mounting plates 4 on both sides, the two sides of the headrest body 2 can be stretched outward or contracted inward. When the headrest body 2 is stretched outward through the mounting plates 4 on both sides, the density of the filling inside the headrest body 2 can be reduced, thereby improving the hardness of the headrest body 2. When the headrest body 2 is contracted inward through the mounting plates 4 on both sides, the density of the filling inside the headrest body 2 can be increased, thereby reducing the hardness of the headrest body 2.
[0029] The back plate 1 is fixedly connected to the bottom with a back column 11, and the bottom of the back column 11 is connected to two support columns 13 through a plurality of reinforcing columns 12, and the tops of the support columns 13 are inserted into the headrest body 2 and fixedly connected thereto. The support columns 13 are connected to the chair of the golf cart, and the headrest adjustment mechanism can be fixedly installed by setting the support columns 13. It is worth noting that the connection structure between the support columns 13 and the chair of the golf cart is the existing technology currently disclosed on the market, and it does not belong to the main technical problem to be solved in the present technical solution, so it is not elaborated in the present invention.
[0030] Among them, a mounting groove 21 is provided at the rear of the headrest body 2, the mounting plate 4 is "L-shaped" and adapted to the mounting groove 21, and the sides of the mounting plate 4 are fixedly connected to the sides of the mounting groove 21. The two sides of the mounting plate 4 are fixedly connected to the headrest body 2, while the inner wall of the mounting plate 4 is not fixed to the headrest body 2, so that the mounting plates 4 on both sides can only stretch the two sides of the headrest body 2. And it is worth noting that the outer fabric of the headrest body 2 is elastic material, so that the headrest body 2 will not be damaged during the stretching process.
[0031] Among them, a plurality of transverse cavities 41 are opened inwardly on one side of the mounting plate 4, and the transverse cavities 41 are all adapted to the transverse pillars 14, and a vertical cavity 42 is opened inside the mounting plate 4. The vertical pillars 15 are adapted to be located in the vertical cavity 42 for movement, and the vertical cavity 42 is connected to the transverse cavity 41, and the ends of the vertical cavity 42 are closed. Through the adaptation setting between the vertical cavity 42 and the vertical pillars 15, when the mounting plate 4 is located on the transverse pillar 14 and moves, it can be ensured that the mounting plate 4 will not fall off the transverse pillar 14.
[0032] Among them, a plurality of guide posts 18 are fixedly and vertically arranged in the groove 17 on the back plate 1, and guide holes 34 are adapted to be opened on the corresponding guide posts 18 on the limit plate 3, and anti-dropping parts 19 are fixedly arranged at the ends of the guide posts 18. The movement of the limit plate 3 can be guided by the arrangement of the guide posts 18, and the anti-dropping parts 19 can prevent the limit plate 3 from falling off from the guide posts 18.
[0033] Among them, sub-plates 191 are fixedly arranged on both sides of the anti-dropping member 19, springs 33 are installed on the sub-plates 191, and the other ends of the springs 33 are connected to the limit plate 3. Through the arrangement of the springs 33, a thrust can be provided to the limit plate 3, so that the limit plate 3 can be located in the groove 17 due to the elastic force of the springs 33 at ordinary times.
[0034] Among them, side plates 31 are fixedly provided on both sides of the limiting plate 3, and the side plates 31 are all facing the mounting plate 4, and multiple limiting columns 32 are fixedly and vertically provided on the side plates 31. Multiple second limiting holes 43 are adapted to correspond to the limiting columns 32 on the mounting plate 4, and the limiting columns 32 are inserted into the cross column 14 through the second limiting holes 43, and the cross column 14 is provided with a first limiting hole 16 adapted to the limiting column 32. The mounting plate 4 can be fixed by the adaption and clamping between the limiting column 32 and the first limiting hole 16. And because the cross column 14 is provided with an adapted first limiting hole 16, the user can fix the limiting plate 4 at different positions by clamping the limiting column 32 in different first limiting holes 16.
[0035] In this embodiment, the two sides of the headrest body 2 can be stretched outward or contracted inward by moving the mounting plates 4 on both sides. When the headrest body 2 is stretched outward by the mounting plates 4 on both sides, the density of the filling material inside the headrest body 2 can be reduced, thereby improving the hardness of the headrest body 2. When the headrest body 2 is contracted inward by the mounting plates 4 on both sides, the density of the filling material inside the headrest body 2 can be increased, thereby reducing the hardness of the headrest body 2.
[0036] Furthermore, when the user needs to control the installation plates 4 on both sides to move, he only needs to pull the limit plate 3 outward, at which time the spring 33 is compressed, and the limit posts 32 on both sides of the limit plate 3 are separated from the first limit holes 16 in the horizontal column 14 and the second limit holes 43 on the installation plate 4. At this time, the limit posts 32 release the clamping of the installation plate 4, and the user can freely move and adjust the installation plate 4.
[0037] Further, after the user has adjusted the mounting plates 4 on both sides, he only needs to loosen the limiting plate 3, and the limiting plate 3 can be automatically reset to the groove 17 by the elastic force of the spring 33. At this time, the limiting posts 32 on both sides of the limiting plate 3 move synchronously with the limiting plate 3, and the limiting posts 32 will pass through the second limiting hole 43 again to enter the first limiting hole 16, so that the mounting plate 4 can be clamped, and the hardness of the headrest body 2 can be adjusted. It is worth noting that since the fabric on the outside of the headrest body 2 is elastic, when the limiting posts 32 pass through the second limiting hole 43 but are not aligned with the first limiting hole 16, the contraction of the headrest body 2 can drive the mounting plates 4 on both sides to move slowly inward. When the first limiting hole 16 on the mounting plate 4 that is closest to the limiting posts 32 is aligned, the limiting posts 32 can automatically move into the first limiting hole 16, so that the mounting plate 4 can be clamped.
[0038] In the present invention, by setting the back plate 1 and the limit plate 3, the adjustment of the mounting plates 4 on both sides can be conveniently realized. By adjusting the mounting plates 4 on both sides, the headrest body 2 can be stretched, thereby realizing the adjustment of the hardness of the headrest body 2. In this way, the user can freely adjust the looseness of the headrest body 2, thereby improving the user's comfort.
[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
