[0036] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor also belong to the protection scope of the present application.

[0037] In order to make those skilled in the art better understand the present application, the present application will be further described in detail with reference to the drawings and specific embodiments.​

[0038] It should be noted that the "upper end, lower end, left side, right side" and other orientation words described below are defined based on the drawings of the specification.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic view of the elastic seat in the embodiment of the application. Figure 2 is Figure 1 a structural schematic view of part A in the embodiment of the application.

[0040] The elastic seat provided by the embodiment of the application comprises an elastic base 10 and a seat body 20.

[0041] The elastic base 10 comprises a base body 11 and an elastic structure 12, the elastic structure 12 is connected between the base body 11 and the seat body 20, and the elastic structure 12 is used to deform under the condition that the seat body 20 bears pressure.

[0042] As can be seen, the elastic structure 12 can elastically deform to a certain extent according to the weight and sitting posture of the user on the seat body 20, so as to provide better support and comfort and realize the rocking experience of the elastic seat.

[0043] Moreover, the elastic base 10 further comprises an elastic limiting piece 13, the elastic limiting piece 13 is arranged on the base body 11 and located below the elastic structure 12, the elastic limiting piece 13 is specifically arranged on the base body 11 near the rear end of the seat body 20, and the bottom of the seat body 20 is provided with a limiting point 211 at an end away from the elastic limiting piece 13, the distance between the bottom of the seat body 20 and the base body 11 gradually decreases along the direction close to the limiting point 211, or in other words, the bottom support tube of the seat body 20 is designed to tilt towards the front end and downward.

[0044] In this way, the rear end of the elastic base 10 is provided with the elastic limiting piece 13 for limiting the rear leaning angle of the seat body 20, so as to prevent the seat body 20 from excessively leaning back and ensure the safety of the rear leaning of the seat body 20, and at the same time, the bottom of the seat body 20 is provided with a downwardly inclined structure, and the front end of the bottom of the seat body 20 is provided with the limiting point 211, so as to prevent the seat body 20 from excessively leaning forward and ensure the safety of the forward leaning of the seat body 20.

[0045] In this way, compared with the conventional seat, the elastic seat provided by the embodiment of the application not only has the support elasticity of the elastic base 10, but also is respectively provided with the corresponding safety limiting structures for the rear leaning and forward leaning of the seat body 20, so as to prevent the seat body 20 from excessively leaning back and forward and ensure the safety of the rear leaning and forward leaning of the seat body 20.

[0046] That is to say, the elastic seat can not only meet the comfortable rocking experience of the user, but also ensure the safety during the rocking.

[0047] In some embodiments, the base body 11 is provided with a limiting frame 14 for facilitating installation of the elastic limiting member 13, and the elastic limiting member 13 is detachably installed on the limiting frame 14 to limit the reclining angle of the seat back 20.

[0048] It can be understood that the elastic limiting member 13 can be a plastic member integrally formed by injection molding, which has certain strength and elasticity, and can be elastically deformed to a certain extent when the seat back 20 is subjected to pressure, and can also play a certain blocking effect on the elastic plate to prevent the seat back 20 from excessively reclining under the action of pressure.

[0049] In some embodiments, one end of the elastic limiting member 13 is provided with an embedded part 131 for embedding on the limiting frame 14, and the embedded part 131 can be an embedded hole in interference fit with the limiting frame 14. This mounting and dismounting method not only facilitates mounting and dismounting, but also ensures the stability of the elastic limiting member 13 after embedding.

[0050] Furthermore, the end of the elastic limiting member 13 away from the embedded part 131 is provided with a limiting inclined surface 132 for contacting and abutting against the elastic structure 12.

[0051] In this way, the elastic limiting member 13 can be provided in multiple, and the multiple elastic limiting members 13 can be different in specifications such as height and outer diameter, and the elastic limiting members 13 of different specifications can be used to provide safe limiting effect in different use conditions of different users, and the users can select appropriate elastic limiting members 13 according to their own weight and other parameters and embed them on the limiting frame 14.

[0052] In some embodiments, the limiting point 211 is provided with a limiting foot sleeve 212, and the limiting foot sleeve 212 is sleeved on the bottom of the seat back 20 to limit the angle of the seat back 20.

[0053] The limiting foot sleeve 212 is provided with an opening, and the size of the opening can be increased by using the elastic property of the limiting foot sleeve 212 to facilitate the sleeving of the limiting foot sleeve 212 on the bottom support pipe of the seat back 20. The limiting foot sleeve 212 at least includes an arc segment to adapt to the arc edge angle of the bottom of the seat back 20.

[0054] When the seat back 20 is inclined forward to contact the ground with the limiting foot sleeve 212, the limiting foot sleeve 212 can be used to support and limit the angle of the seat back 20 to prevent the seat back 20 from excessively inclining forward and ensure the safety of the seat.

[0055] In some embodiments, the elastic structure 12 is specifically an elastic plate, which is fixedly connected by a first fixing assembly and a second fixing assembly, wherein the first fixing assembly is fixed to the upper end of the elastic plate, the second fixing assembly is fixed to the lower end of the elastic plate, and the first fixing assembly is fixed to the support pipe at the bottom of the chair body 20, and the second fixing assembly is fixed to the base body 11, so that the two ends of the elastic plate are respectively detachably connected to the bottom of the chair body 20 and the base body 11.

[0056] In some embodiments, the first fixing assembly includes a half-plate 16 and a fastener 17, the half-plate 16 is attached to the outer wall of the bottom of the chair body 20, and the fastener 17 passes through the half-plate 16, the bottom of the chair body 20 and the elastic plate, so that the elastic plate is fixed to the bottom of the chair body 20.

[0057] It can be understood that the half-plate 16 can serve as a gasket structure of the fastener 17, for increasing the contact area between the fastener 17 and the bottom of the chair body 20, thereby increasing the stability and reliability of the connection between the elastic plate and the chair body 20. Of course, the half-plate 16 can also be connected to the upper end of the elastic plate, so that on the one hand, the half-plate 16 can serve as a part of the elastic plate for half-wrapping the support pipe at the bottom of the chair body 20, and on the other hand, it can also simultaneously serve as a gasket structure of the fastener 17 for increasing the contact area between the fastener 17 and the bottom of the chair body 20, thereby increasing the stability and reliability of the connection between the elastic plate and the chair body 20.

[0058] In some embodiments, the base body 11 is provided with an angle bracket 15, and the other end of the elastic plate is detachably connected to the angle bracket 15 by a fastening screw, so that the elastic plate and the base body 11 maintain a preset included angle.

[0059] Specifically, the angle bracket 15 is provided with a mounting surface, which is an inclined surface (presents a preset included angle with the top surface of the base body 11), and when the other end of the elastic plate is connected to the mounting surface of the angle bracket 15 by a fastening screw, the elastic plate as a whole is inclinedly arranged at a preset included angle with the top surface of the base body 11.

[0060] Of course, according to actual needs, the above-mentioned elastic plate can be an elastic steel plate, which can be deformed under the action of pressure on the chair body 20, and at the same time has a certain strength, so as to realize the rocking function by means of the lever principle and the elasticity of the elastic steel plate itself, so that the back of the user is relaxed and a more comfortable rocking experience is obtained.

[0061] It needs to be emphasized that compared with the existing elastic base 10, the installation of the elastic plate eliminates the relatively complex upper support bracket and lower support bracket, so that the structure is simple, the installation is convenient, the cost is reduced, and the noise is reduced.

[0062] In some embodiments, the base body 11 comprises a sleeve 111 and a telescopic rod 112 embedded in the sleeve 111, the telescopic rod 112 can be telescopically moved relative to the sleeve 111 to extend relative to the sleeve 111 when the elastic seat is in use, and to retract relative to the sleeve 111 when the elastic seat is in transportation.

[0063] That is, the base body 11 with telescopic design can retract the telescopic rod 112 relative to the sleeve 111 when the elastic seat is in non-working state (such as storage or transportation state), so as to reduce the overall size of the base body 11, reduce the occupied space of the base body 11, and improve the convenience of transportation; and the telescopic rod 112 can be extended relative to the sleeve 111 to a certain length when the elastic seat is in working state, so as to increase the overall support stability of the base body 11.

[0064] In some embodiments, the end of the sleeve 111 away from the limiting point 211 is provided with an inner plug 113, and the inner plug 113 is in frictional contact with the telescopic rod 112.

[0065] As can be seen, the inner plug 113 acts as a damping plug for the telescopic movement of the telescopic rod 112, and is used to provide damping during the telescopic movement of the telescopic rod 112 relative to the sleeve 111, so as to ensure that the telescopic rod 112 stably stays at any extended or retracted position.

[0066] Of course, according to actual needs, the end of the sleeve 111 and the telescopic rod 112 is provided with a support foot sleeve 114. The corresponding support foot sleeve 114 can play a role in protecting the sleeve 111 and the telescopic rod 112.

[0067] In some embodiments, the chair body 20 comprises two oppositely arranged support frames 21, the bottom of the support frame 21 is designed to tilt towards the front end and downward, and the top of the support frame 21 is designed to tilt towards the front end and upward, so as to ensure the stability of the chair body 20 supporting the user.

[0068] In addition, in order to facilitate the storage of the chair body 20, a cross pipe assembly 22 is hinged between the two support frames 21, and the two support frames 21 are unfolded and folded through the cross pipe assembly 22.

[0069] Specifically, the cross pipe assembly 22 comprises two cross-shaped and hingedly arranged U-shaped frames, one end of one of the U-shaped frames is hinged to one of the support frames 21 through a hinge rod, and the other end is hinged to the other support frame 21, and the two U-shaped frames are arranged in the same way to ensure that the chair body 20 is folded and stored when the two U-shaped frames are folded.

[0070] It should be noted that the relative terms, such as first and second, are used herein only to differentiate one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.

[0071] The above has carried on the detailed introduction to the elastic seat provided by the application. The principle and implementation mode of the application are described by applying specific examples in this paper, and the above example description is only used to help understand the scheme of the application and its core idea. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and modifications can be made to the application without departing from the principle of the application, and these improvements and modifications also fall within the protection scope of the application.
