[0002] With the improvement of people's living standards and the change of consumption concepts, the demand for entertainment is growing, and cinemas, as important leisure and entertainment venues, are becoming increasingly prominent. Furthermore, audiences' demands for the movie-watching experience are constantly rising, prompting cinemas to comprehensively upgrade their facilities and services. Major cinema brands are attracting audiences by enhancing the movie-watching experience and optimizing services.

[0003] The comfort of cinema seats is an important part of the audience's movie-watching experience. Modern cinema seats emphasize ergonomic design, providing a comfortable viewing posture for the audience through reasonable seat angles, heights, and material selection. However, existing cinema seats generally adopt a frame structure fixed to the cinema viewing platform, and their height is fixed. When encountering consumers of different heights (such as children and adults), the seats may be too low or too high, reducing the consumer's movie-watching experience. In order to solve this problem, this application proposes a cinema seat with an adjustable leg support. Utility Model Content

[0014] Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, through the setting of a lifting mechanism, uses a support frame, a tray, an assembly plate, and a lifting mechanism to provide support for the seat body. During movie viewing, the controller starts the drive motor, which, under the transmission of the second gear and the first gear, drives the bidirectional lead screw to rotate. When the bidirectional lead screw rotates forward, it drives a pair of sliding seats to move away from each other, pushing multiple pairs of support rods to move vertically, thus lifting the tray and the seat body. When the bidirectional lead screw rotates in reverse, it drives a pair of sliding seats to move closer together, causing multiple pairs of support rods to tilt towards the horizontal, thus lowering the tray and the seat body. This allows for adjustment of the seat height to meet the viewing needs of people of different heights.

[0017] This invention features multiple pairs of support rods, and a structural design where the radius of the first gear is larger than that of the second gear, enabling the seat body to be adjusted and raised as smoothly as possible, thus improving the seat's performance.

[0025] 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.

[0026] This embodiment provides a cinema seat with an adjustable leg support, as shown in the schematic diagram below. Figures 1-5As shown, the device includes a seat body 1 and a support frame 2. A mounting plate 4 is horizontally fixed to the top of the support frame 2, and a support plate 3 is horizontally positioned above the mounting plate 4. The seat body 1 is mounted on the support plate 3. A lifting mechanism 5 capable of lifting the support plate 3 is provided on the mounting plate 4. The lifting mechanism 5 includes a pair of side plates 7 fixed to opposite sides of the upper surface of the mounting plate 4, a bidirectional lead screw 8 horizontally rotatably mounted between the pair of side plates 7, and a pair of sliding seats 9 slidably mounted on the upper surface of the mounting plate 4. The pair of sliding seats 9 are perpendicularly distributed to the bidirectional lead screw 8, and the pair of sliding seats 9 are symmetrically threadedly engaged with the bidirectional lead screw 8. The side plates 7 are equipped with mechanisms for driving the bidirectional lead screw 8 to rotate. The drive unit 12 rotates, and each of the tops of the pair of slides 9 is hinged with a support rod 10. The end of the support rod 10 away from the slide 9 is hinged to the lower surface of the support plate 3. With this structure, when the drive unit 12 drives the bidirectional lead screw 8 to rotate forward and move the pair of slides 9 away from each other, it pushes the multiple pairs of support rods 10 to move vertically, which can lift the support plate 3 and the seat body 1. When the drive unit 12 drives the bidirectional lead screw 8 to rotate in reverse and move the pair of slides 9 closer together, it causes the multiple pairs of support rods 10 to tilt towards the horizontal, which can lower the support plate 3 and the seat body 1. This allows for the adjustment of the height of the seat body 1 to meet the viewing needs of people of different heights.

[0027] In this embodiment, multiple pairs of support rods 10 are arranged side by side, and a pair of slides 9 are close to the middle position of the bidirectional lead screw 8. The end of the support rod 10 away from the slide 9 is hinged to the side of the lower surface of the support plate 3 to provide stable support for the seat body 1 as much as possible.

[0028] Furthermore, a slide rod 11 is horizontally fixed between a pair of side plates 7, and the slide rod 11 moves through a pair of slide blocks 9 to guide the translation of the slide blocks 9.

[0029] In this embodiment, the drive component 12 includes a fixed frame 21 fixed on the side of the side plate 7 away from the mounting plate 4 and a drive motor 22 mounted on the fixed frame 21 for driving the bidirectional lead screw 8 to rotate. A controller 13 connected to the drive motor 22 is mounted on the side plate 7. The drive component 12 also includes a first gear 19 and a second gear 20 rotatably mounted on the side plate 7. The first gear 19 is coaxially connected to the bidirectional lead screw 8, and the second gear 20 meshes with the first gear 19. The second gear 20 is coaxially connected to the output shaft of the drive motor 22. The controller 13 controls the drive motor 22 to start. Under the transmission cooperation of the second gear 20 and the first gear 19, the bidirectional lead screw 8 can be driven to rotate to control the lifting and lowering of the seat body 1. The radius of the first gear 19 is larger than the radius of the second gear 20. The support rod 10 is provided with multiple pairs. In addition, the structural design that the radius of the first gear 19 is larger than the radius of the second gear 20 enables the seat body 1 to be lifted and lowered as smoothly as possible, thus improving the performance of the seat.

[0030] In this embodiment, the height of the side plate 7 is greater than the height of the slide 9, and a rubber pad 6 is provided on the upper surface of the support plate 3. When the support plate 3 descends to the lowest point, the support plate 3 can abut against the top of the side plate 7.

[0031] In a further embodiment, the support frame 2 includes a bottom ring frame 14, a top ring frame 15, and uprights 16 vertically connected between the four corners of the bottom ring frame 14 and the top ring frame 15. The mounting plate 4 is fixed on the top ring frame 15, and a protruding plate 17 is horizontally fixed at the bottom of the side wall of the bottom ring frame 14. The protruding plate 17 has mounting holes 18.

[0032] Working principle: During use, bolts are used to fix the support frame 2, consisting of the bottom ring frame 14, the top ring frame 15, and the upright column 16, onto the cinema viewing platform. Then, the seat body 1 is fixed to the support plate 3 with bolts. The support frame 2, together with the support plate 3, the mounting plate 4, and the lifting mechanism 5, can provide support for the seat body 1. During the viewing process, the controller 13 controls the drive motor 22 to start. Under the transmission cooperation of the second gear 20 and the first gear 19, the double-acting lead screw 8 is driven to rotate. When the double-acting lead screw 8 rotates forward, it drives a pair of sliding seats 9 to move away from each other. By pushing multiple pairs of support rods 10 towards vertical movement, the support plate 3 and seat body 1 can be lifted. When the bidirectional lead screw 8 reverses and drives a pair of sliding blocks 9 to move closer together, the multiple pairs of support rods 10 are tilted towards horizontal movement, which in turn causes the support plate 3 and seat body 1 to descend. This allows for height adjustment of the seat body 1 to meet the viewing needs of people of different heights. Because there are multiple pairs of support rods 10, and the structural design of the first gear 19 having a larger radius than the second gear 20, the seat body 1 can be raised and lowered as smoothly as possible, improving the performance of the seat.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
