[0047] The seat surface 100 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0048] As Figure 3 and Figure 7 shown, the seat surface 100 according to an embodiment of the present utility model includes a body 1, a movable component 2, a support plate 3, and a connecting rod assembly 4.

[0049] Specifically, referring to Figure 3 and Figure 7 shown, the movable component 2 is movably disposed at the front end of the body 1 along the front - rear direction of the body 1 (as Figure 7 shown), and the movable component 2 extends along the width direction of the seat surface 100 (the left - right direction shown in reference to Figure 7 the accompanying drawings) for adjusting the seat depth of the seat surface 100. When the movable component 2 moves forward, the distance between the front end of the movable component 2 and the rear end of the seat surface 100 increases, so that the seat depth increases to meet the user's usage requirements.

[0050] Furthermore, referring to Figure 12 and Figure 14 shown, the support plate 3 is located at the front end of the movable component 2 and is rotatably connected to the movable component 2 at the upper end. The support plate 3 extends along the width direction of the seat surface 100 and is an arc - shaped plate protruding towards the front side of the seat surface 100. When a user sits on the seat surface 100, the support plate 3 often fits with the user's thigh or knee to support the user's legs. The design of the arc - shaped plate can improve the user's comfort and the aesthetic degree of the seat surface 100.

[0051] Even further, referring to Figure 3 , Figure 13 and Figure 14 shown, the support plate 3 is connected to the movable component 2 and the body 1 through the connecting rod assembly 4. The support plate 3 is configured to rotate forward and upward at the lower end when the movable component 2 moves forward, which can increase the distance between the front end of the support plate 3 and the rear end of the seat, further increase the seat depth of the seat surface 100, expand the adjustable range of the seat depth of the seat surface 100, and meet the usage requirements of more users.

[0052] It can be understood that the movable component 2 is movable along the front-back direction of the main body 1. When the movable component 2 moves forward, the upper end of the support plate 3 is driven by the movable component 2 to move forward together, and the lower end of the support plate 3 is driven by the link component 4 to move forward and rotate upward, which can increase the seat depth of the seat surface 100; when the movable component 2 retracts backward, the upper end of the support plate 3 is driven by the movable component 2 to move backward together, and the lower end of the support plate 3 is driven by the link component 4 to move backward and rotate downward, and finally returns to the original position, so that the space occupied by the seat surface 100 in the initial state is smaller, thereby realizing the adjustable seat depth of the seat surface 100, improving the compatibility of the seat surface 100, meeting the usage needs of more users, and improving the user experience and comfort. Compared with the prior art in which the seat depth is adjusted by replacing the seat surface or the chassis, the present utility model greatly reduces the difficulty of adjusting the seat depth of the seat surface 100, improves the convenience of adjusting the seat depth of the seat surface 100, shortens the time for adjusting the seat depth of the seat surface 100, and reduces the cost of the seat surface 100.

[0053] For the seat surface 100 according to the embodiment of the present utility model, by providing a movable component 2 at the front end of the main body 1, the movable component 2 is movable along the front-back direction of the main body 1, and a support plate 3 is provided at the front end of the movable component 2. When the movable component 2 moves forward, the upper end of the support plate 3 is driven by the movable component 2 to move forward together, and the lower end of the support plate 3 is driven by the link component 4 to move forward and upward, so that the adjustable seat depth of the seat surface 100 can be realized, the adjustable range of the seat depth of the seat surface 100 is expanded, the compatibility of the seat surface 100 is improved, the usage needs of more users are met, the user experience and comfort are improved. Compared with the prior art in which the seat depth is adjusted by replacing the seat surface or the chassis, the difficulty of adjusting the seat depth of the seat surface 100 is greatly reduced, the convenience of adjusting the seat depth of the seat surface 100 is improved, the time for adjusting the seat depth of the seat surface 100 is shortened, and the cost of the seat surface 100 is reduced.

[0054] In some embodiments of the present utility model, referring to the attached Figure 4 and the attached Figure 9 As shown, the link component 4 includes a first link 41, a second link 42 and a third link 43. One end of the first link 41 is rotatably connected to the main body 1 through a fastener, and a first limiting hole 411 is provided at the other end of the first link 41. The first limiting hole 411 extends along the length direction of the first link 41 (referring to the d direction shown in the attached Figure 9 ), and the first limiting hole 411 is an oblong hole extending along the length direction of the first link 41. A positioning hole 412 is provided at the middle part of the first link 41. The two ends of the second link 42 in the length direction (referring to the e direction shown in the attached Figure 9 ) are respectively rotatably connected to the first link 41 and the movable component 2.

[0055] Specifically, referring to the attached Figure 4 and the attached Figure 9As shown in the figure, one end of the second connecting rod 42 in the length direction has a positioning post 421, the positioning post 421 is inserted into the positioning hole 412, and the other end of the second connecting rod 42 in the length direction is rotatably connected to the movable assembly 2 through a fastener. When the movable assembly 2 moves forward, the second connecting rod 42 drives the first connecting rod 41 to rotate forward. The third connecting rod 43 is movably arranged on the body 1 in the front-back direction. The front end of the third connecting rod 43 is connected to the lower end of the support plate 3, and the rear end of the third connecting rod 43 has a limiting post 431, and the limiting post 431 is inserted into the first limiting hole 411 and is movable along the length direction of the first limiting hole 411 (refer to the Figure 9 d direction shown in the figure). For example, the fastener can be a screw.

[0056] It can be understood that when the movable assembly 2 moves forward, the upper end of the support plate 3 is driven to move forward together. Since one end of the second connecting rod 42 in the length direction is rotatably connected to the movable assembly 2, the second connecting rod 42 moves forward together with the movable assembly 2. And the other end of the second connecting rod 42 in the length direction is rotatably connected to the first connecting rod 41, and one end of the first connecting rod 41 in the length direction is rotatably connected to the body 1, so that the first connecting rod 41 can only rotate forward and cannot move. Since the limiting post 431 of the third connecting rod 43 is movably inserted into the first limiting hole 411 of the first connecting rod 41, the forward rotation of the first connecting rod 41 will cause the limiting post 431 to move forward in the first limiting hole 411, and then the third connecting rod 43 moves forward to push the lower end of the support plate 3 forward, so as to realize the forward movement of the whole support plate 3, realize the adjustable seat depth of the seat surface 100, improve the compatibility of the seat surface 100, meet the use needs of more users, and improve the user experience and comfort.

[0057] It should be noted that, referring to the Figure 8 figure and the Figure 9 figure shown, one end of the second connecting rod 42 connected to the movable assembly 2 is located in front of the end of the second connecting rod 42 connected to the first connecting rod 41, which can ensure that the second connecting rod 42 drives the first connecting rod 41 to rotate forward. One end of the second connecting rod 42 connected to the first connecting rod 41 is located between the position where the first connecting rod 41 is connected to the body 1 and the first limiting hole 411. It can be understood that when the first connecting rod 41 is driven by the second connecting rod 42 to rotate a certain angle, compared with setting the positioning hole 412 in front of the second limiting hole 451, setting the positioning hole 412 between the position where the first connecting rod 41 is connected to the body 1 and the first limiting hole 411 can relatively shorten the forward movement distance of the second connecting rod 42, reduce the difficulty of the second connecting rod 42 driving the first connecting rod 41 to rotate, and then facilitate the cooperation between the first connecting rod 41 and the third connecting rod 43, and facilitate the third connecting rod 43 to push the support plate 3.

[0058] In a further embodiment of the present invention, referring to the Figure 8 figure and theFigure 9 As shown, the connecting rod assembly 4 further includes a connecting member 44. The front end of the third connecting rod 43 is connected to the support plate 3 through the connecting member 44. The connecting member 44 is rotatably connected to both the third connecting rod 43 and the support plate 3. A first mounting lug 432 is provided at the front end of the third connecting rod 43. On the side of the support plate 3 facing the third connecting rod 43, there is a second mounting lug 31. The connecting member 44 is rotatably connected to both the first mounting lug 432 and the second mounting lug 31 through fasteners, and the connection point of the connecting member 44 with the first mounting lug 432 and the connection point of the connecting member 44 with the second mounting lug 31 are spaced apart. The setting of the connecting member 44 can prevent the support plate 3 and the third connecting rod 43 from interfering with each other, ensure the normal rotation of the support plate 3, and further ensure the stability of the seat surface 100 in adjusting the seat depth and the reliability of the seat surface 100. For example, the fasteners can be mother and son screws.

[0059] In a further embodiment of the present utility model, refer to the attached Figure 4 and the attached Figure 9 As shown, the connecting rod assembly 4 further includes a limiting assembly 45. The limiting assembly 45 is provided on the body 1. The limiting assembly 45 is provided with a second limiting hole 451 and a chute 452 extending in the front-rear direction. The third connecting rod 43 is movably arranged in the chute 452. The second limiting hole 451 is an oblong hole extending in the front-rear direction. The limiting post 431 is inserted into the second limiting hole 451. The setting of the limiting assembly 45 can limit the moving direction of the third connecting rod 43, prevent the third connecting rod 43 from being driven by the first connecting rod 41 to rotate, ensure the movement of the third connecting rod 43 in the front-rear direction, and ensure the movement of the third connecting rod 43 driving the support plate 3.

[0060] Specifically, refer to the attached Figure 4 As shown, the limiting assembly 45 includes a limiting base 453 and a limiting top cover 454 arranged and connected in the up-down direction (as Figure 4 shown). The limiting base 453 and the limiting top cover 454 jointly define the chute 452. The second limiting hole 451 is provided on the limiting top cover 454. The limiting top cover 454 is fixed to the body 1 by four screws. The first connecting rod 41 is located above the limiting assembly 45. At least part of the second limiting hole 451 is arranged opposite to the first limiting hole 411. The limiting post 431 of the third connecting rod 43 sequentially passes through the second limiting hole 451 and the first limiting hole 411.

[0061] It should be noted that multiple connecting rod assemblies 4 can be arranged at intervals in the left-right direction. Both the connecting member 44 and the limiting assembly 45 are multiple corresponding to the multiple connecting rod assemblies 4, and can be in the length direction of the support plate 3 (as Figure 11Connect the support plate 3 to the link assembly 4 at multiple locations spaced apart in the left - right direction (as shown), so as to drive the support plate 3 from multiple locations, avoid bending or tilting of the support plate 3 caused by driving it from only a single location, and avoid the situation that the lower end of the support plate 3 cannot be driven due to insufficient driving force, thereby ensuring the driving effectiveness of the link assembly 4 on the support plate 3, ensuring the reliability of the rotation of the support plate 3, and improving the stability of the adjustment of the seat surface 100.

[0062] In some embodiments, refer to the attached Figure 11 and the attached Figure 13 As shown, there are two link assemblies 4 arranged at intervals in the left - right direction. Both the connecting member 44 and the limiting assembly 45 are two corresponding to the two link assemblies 4 respectively, and can drive the support plate 3 from two locations spaced apart in the length direction of the support plate 3, ensuring the reliability of driving the support plate 3.

[0063] In some embodiments of the present utility model, refer to the attached Figure 3 and the attached Figure 10 As shown, the seat surface 100 further includes a driving assembly 5. The driving assembly 5 is fixed to the main body 1 and is used to drive the movable assembly 2 to move in the front - rear direction, so as to control the position of the movable assembly 2 in the front - rear direction according to the user's needs, control the distance between the front end of the movable assembly 2 and the rear end of the seat surface 100, adjust the seat depth of the seat surface 100, and improve the user experience and comfort.

[0064] Of course, the present utility model is not limited to this. The movable assembly 2 can also be directly pushed or pulled by hand. When it is necessary to extend the seat depth, pull out the movable assembly 2 by hand, and when it is not necessary to extend the seat depth, push the movable assembly 2 back to its original position by hand.

[0065] In a further embodiment of the present utility model, refer to the attached Figure 5 , the attached Figure 12 and the attached Figure 14 As shown, in combination with referring to the attached Figure 8 and the attached Figure 9, the movable component 2 is provided with a mating hole 21 whose axis extends in the front-rear direction. The driving component 5 includes a mating rod 51 and a rotating rod 52. The mating rod 51 is rotatably arranged on the body 1. The mating rod 51 penetrates through the mating hole 21 in the front-rear direction and is in threaded cooperation with the mating hole 21. The mating rod 51 has a first helical tooth 511. The rotating rod 52 is rotatably arranged on the body 1 and extends in the left-right direction. The rotating rod 52 has a second helical tooth 521. The second helical tooth 521 meshes with the first helical tooth 511 and is used to drive the movable component 2 to move in the front-rear direction. Through simple threaded cooperation and helical tooth cooperation, the transmission between the mating rod 51 and the rotating rod 52 can be made smoother and more labor-saving, improving the transmission efficiency between the mating rod 51 and the rotating rod 52, improving the transmission accuracy between the mating rod 51 and the rotating rod 52, ensuring the accuracy and reliability of the transmission, and further improving the reliability and stability of the adjustment of the seat surface 100.

[0066] It can be understood that when the rotating rod 52 rotates, the second helical tooth 521 on the rotating rod 52 rotates accordingly. Since the first helical tooth 511 meshes with the second helical tooth 521, the second helical tooth 521 drives the first helical tooth 511 to rotate, thereby causing the mating rod 51 to rotate. Since the mating rod 51 is threadedly connected to the mating hole 21 and the mating rod 51 cannot move in the front-rear direction, the movable component 2 moves in the front-rear direction, thereby driving the support plate 3 to move in the front-rear direction and driving the link assembly 4 to move, realizing the adjustable seat depth of the seat surface 100, improving the compatibility of the seat surface 100, meeting the usage requirements of more users, and improving the user experience and comfort.

[0067] Furthermore, referring to the attached Figure 4 As shown, the driving component 5 further includes a fixed upper cover 54 and a fixed lower cover 55. During the assembly process, first fix the fixed lower cover 55 to the body 1 through two screws, then insert the mating rod 51 into the mating hole 21, place one end of the first helical tooth 511 of the rotating rod 52 and one end of the second helical tooth 521 of the mating rod 51 into the fixed lower cover 55, mesh the second helical tooth 521 with the first helical tooth 511, and finally fix the fixed upper cover 54 to the fixed lower cover 55 through four screws, thereby realizing the positioning and fixation of the rotating rod 52 and the mating rod 51 and ensuring the reliable cooperation between the rotating rod 52 and the mating rod 51. It should be noted that both the fixed upper cover 54 and the fixed lower cover 55 are plastic parts.

[0068] In a further embodiment of the present utility model, referring to the attached Figure 1 and the attached Figure 2 and the attached Figure 8As shown, the driving assembly 5 further includes a rotating handle 53. The rotating handle 53 is located on one side of the seat surface 100 in the width direction. The rotating rod 52 is connected to the rotating handle 53 and rotates synchronously. The rotating handle 53 is convenient for the user to grip. And the rotating handle 53 is arranged on one side of the seat surface 100 in the width direction. Whether the user is sitting on the seat surface 100 or not, it is relatively convenient to rotate the rotating handle 53. When the user rotates the rotating handle 53, the rotating handle 53 drives the rotating rod 52 to rotate together. Through the engagement of the second helical gear 521 and the first helical gear 511, the mating rod 51 starts to rotate. Since the mating rod 51 is threadedly connected to the mating hole 21 and the mating rod 51 cannot move in the front-rear direction, the movable assembly 2 moves in the front-rear direction, thereby realizing the adjustable seat depth of the seat surface 100.

[0069] In a further embodiment of the present invention, the driving assembly 5 is an electric push rod. The electric push rod extends in the front-rear direction and is connected to the movable assembly 2 to drive the movable assembly 2 to move in the front-rear direction. The electric push rod has excellent controllability and can drive the movable assembly 2 to move in the front-rear direction with extremely high precision and repeatability, ensuring the control accuracy of the electric push rod for the movable assembly 2. The structure of the electric push rod is relatively simple, easy to design and maintain, reducing the maintenance cost of the seat surface 100. And the electric push rod can be self-locked after power-off, keeping the current position unchanged, avoiding the movable assembly 2 from continuing to move in the front-rear direction and preventing the seat surface 100 from moving again after the adjustment is completed.

[0070] In some embodiments of the present invention, refer to the attached Figure 5 and the attached Figure 6 As shown, the body 1 includes a main body 11 and a fixing plate assembly 12. The fixing plate assembly 12 is arranged at the front end of the main body 11 and defines an installation space 121. The front side of the installation space 121 is open. At least part of the movable assembly 2 and the link assembly 4 are located in the installation space 121. The support plate 3 is located in front of the installation space 121. The fixing plate assembly 12 includes a first fixing plate 122 and a second fixing plate 124. The first fixing plate 122 and the second fixing plate 124 are arranged in the up-down direction. The first fixing plate 122 is welded to the front end of the main body 11. The first link 41, the limit base 453 and the fixed lower cover 55 of the link assembly 4 are all fixed to the first fixing plate 122 through fasteners, which can ensure the stability of the fixation of the first link 41, the limit base 453 and the fixed lower cover 55. The second fixing plate 124 is covered above the first fixing plate 122 and is fixedly connected to the first fixing plate 122 through fasteners to protect the movable assembly 2, the link assembly 4, the driving assembly 5, etc. from above, and can provide a flat surface on the upper side, facilitating the user to sit down and avoiding affecting the user experience due to the movement of components such as the movable assembly 2.

[0071] In a further embodiment of the present invention, refer to the attachedFigure 5 and the attached Figure 6 As shown, at least one end of the movable component 2 in the left - right direction is sleeved with a friction slider 22. The friction slider 22 is located between the movable component 2 and the inner wall of the installation space 121. The friction slider 22 can move along the front - back direction together with the movable component 2, reducing the friction between the movable component 2 and the inner wall of the installation space 121, facilitating the movement of the movable component 2 along the front - back direction, reducing the noise caused by the friction between the movable component 2 and the fixed component, and improving the user experience.

[0072] Specifically, referring to the attached Figure 5 and the attached Figure 6 As shown, both ends of the first fixing plate 122 in the length direction (the left - right direction shown in the attached Figure 5 figure) have first sliding grooves 123. Both ends of the second fixing plate 124 in the length direction (the left - right direction shown in the attached Figure 5 figure) have second sliding grooves 125. Both ends of the first fixing plate 122 in the length direction are respectively located in the two second sliding grooves 125. The movable component 2 includes a control member 23 and a movable frame 24. The control member 23 and the movable frame 24 are stacked in the up - down direction and connected by fasteners. The mating hole 21 is provided on the control member 23. The support plate 3 is connected to the front end of the control member 23 by a mother - son screw. The second connecting rod 42 is connected to the front end of the movable frame 24 by fasteners. Both ends of the movable frame 24 in the length direction (the left - right direction shown in the attached Figure 5 figure) extend into the first sliding grooves 123. The friction slider 22 is sleeved on at least one end of the movable frame 24 in the length direction, and the friction slider 22 is located between the movable frame 24 and the inner wall of the first sliding groove 123, and can move along the front - back direction together with the movable frame 24, reducing the friction between the movable frame 24 and the inner wall of the first sliding groove 123, ensuring the smooth movement of the movable frame 24 along the front - back direction, facilitating the movement of the movable component 2 along the front - back direction, reducing the noise caused by the friction between the movable frame 24 and the first fixing plate 122, and improving the user experience. It should be noted that both the body 1 and the movable frame 24 are carbon steel parts.

[0073] It should be noted that referring to the attached Figure 1 and the attached Figure 2 and the attached Figure 3 As shown, the seat surface 100 further includes a seat cushion 6. The seat cushion 6 includes sponge and sewn leather. The sponge is wrapped with sewn leather and placed on the body 1. The front - end covering leather of the sponge is fixed on the lower - end plane of the support plate 3 by staple nails, and the other surrounding sewn leather is fixed by annular nails in sequence to complete the installation of the seat cushion 6. The setting of the seat cushion 6 can ensure the comfort of the user when sitting on the seat surface 100 and improve the user experience.

[0074] It can be understood that when the user rotates the rotary handle 53 clockwise, the rotary rod 52 rotates clockwise. Through the cooperation of the first helical gear 511 and the second helical gear 521, the mating rod 51 starts to rotate clockwise (viewed from the front side of the seat surface 100). Since the mating rod 51 is threadedly connected to the mating hole 21 and the mating rod 51 cannot move in the front-rear direction, the control member 23 moves forward. The front end of the control member 23 is rotatably connected to the support plate 3, causing the support plate 3 to move forward; since the control member 23 is fixedly connected to the movable frame 24, when the movable frame 24 moves forward, it drives the second connecting rod 42 to move forward. The positioning post 421 at one end in the length direction of the second connecting rod 42 is inserted into the positioning hole 412 of the first connecting rod 41, causing the second connecting rod 42 to drive the first connecting rod 41 to rotate forward and push the third connecting rod 43 forward. The front end of the third connecting rod 43 is rotatably connected to the support plate 3 through the connecting member 44, thereby pushing the lower end of the support plate 3 to rotate forward and upward. When the connection point between the support plate 3 and the control member 23 moves forward by 2.5 cm and the connection point between the connecting member 44 and the first mounting lug 432 moves forward by 5 cm, the maximum state of the support plate 3 extending forward and rotating upward is reached, making the seat depth the largest. And because the entire support plate 3 extends forward, it can tighten the seam leather of the seat cushion 6, avoid wrinkles on the seat surface 100, and ensure the beauty of the surface of the seat surface 100.

[0075] The present utility model also proposes a seat having the seat surface 100 of the above embodiment.

[0076] For example, the seat can be an e-sports chair. The seat surface 100 is applied to the e-sports chair and can adjust the seat depth of the e-sports chair, improving the user experience.

[0077] According to the seat of the embodiment of the present utility model, by providing the above-mentioned seat surface 100, and by providing a movable component 2 at the front end of the body 1, the movable component 2 is movable along the front-rear direction of the body 1, and a support plate 3 is provided at the front end of the movable component 2. When the movable component 2 moves forward, the upper end of the support plate 3 is driven by the movable component 2 to move forward together, and the lower end of the support plate 3 is driven by the connecting rod assembly 4 to move forward and upward, which can realize the adjustable seat depth of the seat surface 100, expand the adjustable range of the seat depth of the seat surface 100, improve the compatibility of the seat surface 100, meet the usage requirements of more users, improve the user experience and comfort. Compared with the prior art of adjusting the seat depth by replacing the seat surface 100 or the chassis, it greatly reduces the difficulty of adjusting the seat depth of the seat surface 100, improves the convenience of adjusting the seat depth of the seat surface 100, shortens the time for adjusting the seat depth of the seat surface 100, and reduces the cost of the seat surface 100.
