Description

Technical Field

[0001] The utility model belongs to the technical field of gaming chairs, and in particular relates to a gaming chair with a backrest capable of automatically returning to its original position. Background Art

[0002] Gaming chairs, also known as gaming chairs, are chairs designed for e-sports players and users who use computers for long periods of time. Such chairs usually have ergonomic designs that aim to provide comfortable sitting and support to reduce fatigue and discomfort during long periods of gaming or working.

[0003] In order to cater to the users' seat leaning habits in different usage scenarios, the existing gaming chairs all have a structural design with adjustable angle for the backrest. However, since the backrest angle is difficult to automatically reset after the chair is used, when switching to the previous usage scenario, such as switching from a resting state to a gaming state, the user needs to readjust his or her comfortable posture, which makes the steps very cumbersome.

[0004] In summary, there is a need for a gaming chair with a backrest that can automatically return to its original position. Utility Model Content

[0005] The utility model aims to provide a gaming chair with an automatically returnable backrest. When a user sits on the seat plate, the user's own weight is used to press down the seat plate, and the rotation axis of the backrest is locked by a pin rod, thereby ensuring the stability of the backrest angle during the use of the gaming chair. When the user leaves the gaming chair, the pin rod cancels the lock so that the backrest can automatically return to its original position.

[0006] The technical solution adopted by the utility model to solve the above problems is: an e-sports chair with a backrest that can automatically return to its original position, comprising:

[0007] A seat, wherein a groove is provided on the top of the seat, a seat plate is provided in the groove, and an elastic component is provided between the seat plate and the seat;

[0008] One side of the seat is rotatably connected to a chair back via a rotating shaft, and the bottom center of the seat is rotatably connected to a supporting foot;

[0009] A movable plate is movably connected to one side of the inner cavity bottom of the groove, and a second connecting rod is symmetrically hinged between the movable plate and the bottom of the seat plate through a hinge;

[0010] The top of the movable plate is symmetrically fixedly connected with a pin rod, and the pin rod is slidably connected to the seat;

[0011] A plurality of pin holes are provided on the circumference of the rotating shaft, and the pin rods are used to be inserted into the pin holes;

[0012] A reset assembly is used to restore the chair back to an upright state.

[0013] Among them, the upright and reclined states of the seat back refer to the change in the angle of the seat back relative to the seat plane. This change is usually achieved through the tilt mechanism of the seat back, allowing the user to adjust the angle of the seat back as needed to adapt to different usage scenarios and personal preferences. When the seat back is in the upright state, the seat back usually forms an angle close to vertical with the seat plane, or at least a smaller angle. This state is suitable for situations where the user needs to maintain an upright sitting posture, such as playing games, working, studying, or doing activities that require concentration. The upright state helps maintain a good sitting posture and reduces pressure on the back and neck.

[0014] When the seat back is in the reclined position, it forms a larger angle relative to the seat plane, sometimes even reaching a nearly lying angle. This state is suitable for users who need to rest, relax or perform activities that do not require concentration. The reclined state helps reduce tension in the back muscles and provide a more comfortable rest experience.

[0015] A further preferred technical solution is that the reset assembly includes a sliding rod symmetrically fixedly connected to the bottom of the seat through a connecting seat, a sliding plate is slidably connected to the sliding rod, a first connecting rod is hinged between the sliding plate and the bottom of the chair back through a hinge, and a second spring is sleeved on the outside of the sliding rod.

[0016] A further preferred technical solution is that the elastic component includes a telescopic rod arranged at the bottom of the inner cavity of the groove, and a first spring is sleeved on the outside of the telescopic rod.

[0017] A further preferred technical solution is that armrests are fixedly connected to both sides of the seat via brackets.

[0018] A further preferred technical solution is that two ends of the second spring are fixedly connected to the connecting seat and the slide plate respectively.

[0019] A further preferred technical solution is that two ends of the first spring are fixedly connected to the bottom of the inner cavity of the groove and the seat plate respectively.

[0020] A further preferred technical solution is that a headrest is provided on the upper part of the chair back.

[0021] A further preferred technical solution is that a universal wheel is movably provided at the bottom of the supporting foot, and a locking piece is provided on the universal wheel.

[0022] A further preferred technical solution is that a guide slider is fixedly connected to the bottom of the movable plate, and a guide slot is provided at the bottom of the inner cavity of the groove and is slidably connected to the guide slider.

[0023] A further preferred technical solution is that the cross-sectional diameter of the pin rod is not larger than the aperture of the pin hole.

[0024] In summary, the utility model has the following benefits:

[0025] 1. The utility model can drive the chair back to change its angle by rotating the rotating shaft, and utilizes the sliding cooperation between the sliding rod and the sliding plate, and the hinged action between the sliding plate, the chair back and the first connecting rod, so that the chair back can push the sliding plate to compress the second spring during the process of changing its angle. When the user sits on the seat plate, the user's own weight is utilized, and the seat plate can be pressed down under the cooperation of the telescopic action of the telescopic rod and the elastic action of the first spring. When the seat plate moves downward, the sliding cooperation between the guide slider and the guide slide groove, and the hinged action between the movable plate, the seat plate and the second connecting rod are utilized, so that the movable plate can be pushed to move horizontally. The movement of the movable plate drives the pin rod to move together, so that the pin rod can be inserted into the pin hole to lock the rotating shaft, thereby ensuring the stability of the chair back angle during the use of the gaming chair.

[0026] 2. When the user leaves the gaming chair, the first spring and the second spring work together to allow the chair back to automatically return to its original position. The utility model is highly practical and effectively avoids the problem that the chair back angle is difficult to automatically return to its original position after the chair has been used, which increases the complexity of the user's operation.

[0034] Please combine Figure 1-3 , a gaming chair with a backrest that can automatically return to its original position in this embodiment includes:

[0035] A seat 1, a groove is provided on the top of the seat 1, a seat plate 2 is arranged inside the groove, a telescopic rod 3 is evenly fixedly connected between the bottom of the seat plate 2 and the bottom of the inner cavity of the groove, the telescopic rod 3 is a prior art, and is composed of a sleeve and a sleeve rod with one end limited and movably connected to the inside of the sleeve, a first spring 4 is sleeved on the outside of the telescopic rod 3, and the two ends of the first spring 4 are respectively fixedly connected to the bottom of the inner cavity of the groove and the seat plate 2, a seat back 5 is rotatably connected to one side of the seat 1 through a rotating shaft, a support foot 6 is rotatably connected to the bottom center of the seat 1, and armrests 7 are fixedly connected to both sides of the seat 1 through brackets, the seat back 5 is a streamlined structure design as a whole, which is convenient for fitting the user's back to increase comfort, a headrest 8 is arranged on the upper part of the seat back 5, which can protect the user's cervical vertebra, and a breathable cushion is arranged on the top of the seat plate 2, which can increase the breathability and comfort while improving the softness of the gaming chair;

[0036] The reset assembly includes a slide bar 101 symmetrically fixedly connected to the bottom of the seat 1 through a connecting seat, the two sets of slide bars 101 are slidably connected to the same slide plate 102 on the outside, and the slide plate 102 is symmetrically hinged to the bottom of the chair back 5 through a hinge. A first connecting rod 103 is symmetrically hinged between the slide plate 102 and the bottom of the chair back 5, and a second spring 104 is sleeved on the outside of the slide bar 101. The two ends of the second spring 104 are respectively fixedly connected to the connecting seat and the slide plate 102. A movable plate 105 is movably connected to one side of the bottom of the inner cavity of the groove, and the movable plate 105 is hinged to the bottom of the seat plate 2. The second connecting rod 106 is symmetrically hinged on the top of the movable plate 105, and the pin rod 107 is symmetrically fixedly connected to the top of the movable plate 105 and the pin rod 107 is slidably connected to the seat 1. Pin holes 108 are equidistantly provided on the outside of both sides of the rotating shaft in the circumferential direction. The bottom of the movable plate 105 is symmetrically fixedly connected to the guide slider, and the bottom of the inner cavity of the groove is symmetrically provided with guide grooves 109 which are slidably connected to the guide slider, which can play a certain guiding role in the horizontal movement of the movable plate 105. The diameter of the pin rod 107 is consistent with the diameter of the pin hole 108.

[0037] The implementation principle of an e-sports chair with an automatically return backrest in the embodiment of the present application is as follows: first, the user drives the chair back 5 to deflect by rotating the rotating shaft, and utilizes the sliding cooperation between the slide bar 101 and the slide plate 102, and the hinged action between the slide plate 102 and the chair back 5 and the first connecting rod 103, so that the chair back 5 can push the slide plate 102 to compress the second spring 104 during the angle change process. When the chair back 5 is adjusted to a suitable angle, the hand should not release the rotating shaft at this time. Then the user sits on the seat plate 2, and utilizes the user's own weight, and with the telescopic action of the telescopic rod 3 and the elastic action of the first spring 4, the seat plate 2 can be pressed down. When the seat plate 2 moves downward, the sliding cooperation between the guide slider and the guide slide groove 109 is utilized, and the movable plate 105 and the seat plate 2 and the second connecting rod 106, so that the movable plate 105 can be pushed to move horizontally. The movement of the movable plate 105 drives the pin rod 107 to move together, so that the pin rod 107 can be inserted into the pin hole 108 to lock the rotating shaft, thereby ensuring the stability of the angle of the chair back 5 during the use of the gaming chair. If the pin rod 107 cannot be accurately inserted into the pin hole 108, it is only necessary to slightly rotate the rotating shaft. When the pin hole 108 is aligned with the pin rod 107, the pin rod 107 will automatically insert into the pin hole 108 without causing much impact on the angle of the chair back 5. At this time, the user can release the rotating shaft. Finally, when the user leaves the gaming chair, the rebound effect of the first spring 4 and the rebound effect of the second spring 104 cooperate to make the chair back 5 automatically reset.

[0038] In addition, a further improvement is that a universal wheel is movably provided at the bottom of the supporting foot 6, and a locking piece is provided on the universal wheel. The universal wheel can increase the flexibility of the gaming chair, and the locking piece can lock the universal wheel to improve the stability of the gaming chair when in use.
