[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] In the claims, specification and above-mentioned drawings of the present utility model, the terms "up" and "down" are the same as the up and down directions of the vehicle body, the terms "front" and "rear" are the same as the front and rear directions of the vehicle body, and the terms "left" and "right" are the same as the left and right directions of the vehicle body. These are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the specific scope of protection of the present invention.

[0035] Please also refer to Figures 1 to 13The sliding armrest assembly provided by the present invention will now be described. The sliding armrest assembly is mounted on an armrest frame and comprises: a bearing base 10 and a sliding armrest 20. The bearing base 10 is provided with a slide rail base 102 extending in the front-to-back direction; the sliding armrest 20 moves in the front-to-back direction along the slide rail base 102; a front-to-back movement limiting structure is provided between the sliding armrest 20 and the slide rail base 102 to limit the extreme position of the front-to-back movement of the sliding armrest 20. The front-to-back movement limiting structure comprises a limiting protrusion 215 provided on the sliding armrest 20 and a locking spring 105 provided on the slide rail base 102; a front limiting step 220 and a rear limiting step 219 are provided on the limiting protrusion 215; the locking spring 105 elastically abuts against the limiting protrusion 215 in the left-right direction, and is locked to the front limiting step 220 or the rear limiting step 219 when the sliding armrest 20 moves to the extreme position.

[0036] This application sets the sliding armrest 20 to be in the initial state when it moves forward to the extreme position, which is also the closed state of the sliding armrest 20, and the sliding armrest 20 to be in the open state when it moves backward to the extreme position.

[0037] The sliding armrest assembly provided by the present invention is installed on the armrest frame. The driver and passengers can move the sliding armrest 20 back and forth according to their own body shape, height and the scene they are in, as well as according to the needs and habits of different users, so as to support the arms in a comfortable position, reduce arm fatigue, and thus improve the comfort of the user; when moving back and forth, due to the limitation of the front and rear movement limit structure, it is also possible to provide the driver and passengers with an easy operating experience when moving the sliding armrest 20.

[0038] For passengers of different body shapes, the adjustment examples of the sliding armrest 20 are as follows: for passengers of shorter height, the sliding armrest 20 can be moved backward to avoid discomfort caused by the armrest being too high or too far; while for passengers of tall stature, the sliding armrest 20 can be moved forward to make their elbow support more comfortable.

[0039] Adaptable to different usage scenarios: For example, when working, the armrests can be adjusted closer to the body for convenient computer operation or writing; when resting, the armrests can be slid back to provide more room for movement. This is especially effective for users who sit for long periods of time, such as office workers and long-distance travelers, as it can effectively relieve pressure on the arms and shoulders.

[0040] The supporting base 10 can be fixed to the seat frame by screws, buckles, etc.; similarly, the slide rail base 102 can be fixed to the supporting base 10 by screws, buckles, etc.

[0041] Specifically, see Figure 6 、 Figure 9 、 Figure 10 、 Figure 13 The limiting ridge 215 is provided on the lower surface of the sliding armrest 20 toward the slide rail base 102 and extends along the front and rear directions, and the front and rear ends of the limiting ridge 215 are respectively provided with a front limiting step and a rear limiting step 219; the locking spring piece 105 is provided on the upper surface of the slide rail base 102 toward the sliding armrest 20, and the compression and expansion direction of the locking spring piece 105 is perpendicular to the front and rear directions; when the sliding armrest 20 moves forward and backward, the locking spring piece 105 is pressed by the limiting ridge 215 to store elastic energy. When it moves to the front and rear limit positions, the locking spring piece 105 elastically resets to form abutment with the front limiting step 220 or the rear limiting step 219 in the front and rear directions. When the locking spring piece 105 forms an elastic abutment with the front side surface of the front limit step 220, the sliding armrest 20 is locked at the extreme position of backward movement; when the locking spring piece 105 elastically resets and forms an abutment with the rear side surface of the rear limit step 219, the sliding armrest 20 is locked at the extreme position of forward movement.

[0042] The sliding operation of the present application is simple and convenient, and the user can easily adjust the position of the armrest without complicated tools or operating steps.

[0043] In the present application, both ends of the locking spring piece 105 are limited, and the locking spring piece 105 is in an arc shape, so that the highest point of the arc of the locking spring piece 105 forms a point contact with the side of the limiting protrusion 215, which is beneficial for the locking spring piece 105 to store elastic energy and facilitate the forward and backward sliding of the sliding armrest 20.

[0044] In the present application, locking springs 105 are respectively provided on the left-right symmetrical sides of the slide rail base 102 . Similarly, limiting protrusions 215 are respectively provided on the left-right symmetrical sides of the sliding armrest 20 .

[0045] In some embodiments, see Figure 6 、 Figure 9 、 Figure 10 、 Figure 13 The side surface of the limiting protrusion 215 that abuts the locking spring piece is an arc-shaped surface. When the sliding armrest 20 moves forward and backward, the pressure on the locking spring piece 105 can be reduced, thereby improving the smoothness of the sliding armrest 20 sliding forward and backward.

[0046] In some embodiments, see Figure 6 、 Figure 9 、 Figure 10 、 Figure 13 The locking spring piece 105 is arranged on the outside of the limiting convex strip 215, and the locking spring piece 105 elastically abuts against the inner side surface of the limiting convex strip 215. At this time, the inner side surface of the limiting convex strip 215 is an arc-shaped curved surface.

[0047] Optionally, the locking spring piece 105 is arranged on the outer side of the limiting ridge 215, and the locking spring piece 105 elastically abuts against the outer side surface of the limiting ridge 215. In this case, the outer side surface of the limiting ridge 215 is an arc-shaped curved surface.

[0048] No matter the locking spring piece 105 is located inside or outside the limiting protrusion 215 , when the sliding armrest 20 moves in the front-rear direction, the limiting protrusion moves with the sliding armrest 20 , and can achieve elastic contact and limiting with the locking spring piece 105 .

[0049] The terms "inside" and "outside" are explained as follows: In this application, the forward and backward movement limiting structures are arranged in two groups symmetrically about the centerline extending in the forward and backward directions of the slide rail base 102. Therefore, for ease of description and understanding, the area between the two limiting ridges is defined as the "inside," and the area outside the two limiting ridges is defined as the "outside." In this application, the locking spring is mounted on the slide rail base and can elastically abut against the inside or outside of the limiting ridges.

[0050] In some embodiments, see Figure 9 The rail base 102 is provided with a mounting structure for mounting a locking spring 105. The mounting structure includes a front block 106, a rear block 103, and an upper block 104. The upper block 104 is disposed between the front block 106 and the rear block 103. The locking spring 105 is limited in the space enclosed by the front block 106, the rear block 103, and the upper block 104. No screws or buckles are required for fixing the locking spring 105, making it simple and convenient to install. A slot for limiting the locking spring 105 is formed between the front block 106 and the side surface of the rail base 102. Similarly, a slot is also formed between the rear block 103 and the side surface of the rail base 102.

[0051] In some embodiments, see Figure 6 、 Figure 9 、 Figure 10 、 Figure 13 The lower surface of the sliding armrest 20 is further provided with a front rubber buffer block 210 and a rear rubber buffer block 218. When the sliding armrest 20 moves rearward to its limit position, the front rubber buffer block 210 abuts against the front side of the front stopper 106. When the sliding armrest 20 moves forward to its limit position, the rear rubber buffer block 218 abuts against the rear side of the rear stopper 103. The provision of the front rubber buffer block 210 provides a cushioning effect when the sliding armrest 20 moves forward and contacts the front stopper 106, weakening the impact sensation when the armrest slides and preventing the sliding armrest 20 from making hard contact with the front stopper 106 of the slide rail base 102, which may cause unusual noise and discomfort.

[0052] Specifically, a front baffle 216 and a rear baffle 217 protruding downward are provided on the lower surface of the armrest lower frame 205 of the sliding armrest 20, the front buffer rubber block 210 is bonded, clamped or fixed to the front baffle 216 by screws, and the rear buffer rubber block 218 is fixed to the rear baffle 217.

[0053] In this embodiment, the front baffle 216 and the front buffer rubber block 210 , and the rear baffle 217 and the rear buffer rubber block 218 can also serve as front-to-rear movement limiting structures for the sliding armrest 20 .

[0054] As another embodiment of the front and rear movement limiting structure, it can also be a limiting block set at the front and rear ends of the slide rail 101 of the slide rail base 102. At this time, a buffer rubber pad is set on the vertical surface where the limiting block contacts the slider 202, which can avoid hard collisions and improve the sliding feel.

[0055] In some embodiments, see Figure 8 The lower surface of the sliding armrest 20 is also provided with a lower rubber buffer 209. When the sliding armrest 20 is subjected to a downward force, the lower end surface of the lower rubber buffer 209 elastically contacts the support base 10. For example, when the elbow is supported on the sliding armrest 20, the lower rubber buffer 209 elastically abuts against the support base 10, improving the comfort of the elbow support.

[0056] Specifically, a receiving groove 211 is provided at the front end of the armrest lower frame 205 , and the lower buffer rubber block 209 is clamped in the receiving groove 211 .

[0057] In some embodiments, see Figure 7 The slide rail base 102 is provided with a mounting groove, in which the slide rail 101 is mounted; the sliding handrail 20 is provided with a slider 202 that slides in cooperation with the slide rail 101. The slide rail 101 is fixed to the slide rail base 102 by screws.

[0058] Optionally, the slide rail 101 is a dovetail groove or T-slot structure, and the slider 202 is limited in the slide rail 101. At the same time, in order to ensure the consistency of the front and rear support of the sliding handrail 20, two sliders 202 are fixed on the front and rear of the sliding handrail 20 to form two-point stable support for the sliding handrail 20.

[0059] The present application provides a slide rail 101 on a slide rail base 102, and a slide rail 101 can also be provided on the left and right sides of the slide rail base 102. The sliding armrest 20 uses a slide rail 101 extending forward and backward, and uses two sliders 202 to cooperate with the slide rail 101. The forward and backward sliding is stable, and the extreme positions of the forward and backward movement have a forward and backward movement limit structure. During use, there will be no shaking or loosening, ensuring safety and reliability.

[0060] As another embodiment of the sliding armrest 20, it can also be a rack and a meshing gear arranged between the slide rail base 102 and the lower frame 205 of the armrest. The meshing of the gear and the rack also has the function of stopping and self-locking at any position, so that the sliding armrest 20 can slide to a position that is comfortable for the individual without having to slide to the front and rear extreme positions.

[0061] Optionally, the sliding structure of the sliding handrail 20 may also be the cooperation of the slide rail 101 and the pulley.

[0062] In some embodiments, see Figure 7 The sliding armrest 20 includes a flexible pad 201, an upper armrest frame 203 mounted on the lower surface of the flexible pad 201, and a lower armrest frame 205 mounted on the upper armrest frame 203. The slider 202 is connected to the lower armrest frame 205 via a connecting rod and fasteners. A hidden window is provided on the upper armrest frame 203 to conceal the fasteners. A buffering gasket 204 is also provided between the upper armrest frame 203 and the lower armrest frame 205 to prevent hard contact and noise. The fasteners and connecting rods do not protrude from the upper surface of the upper armrest frame 203 to prevent friction or scratching of the flexible pad 201.

[0063] The lower armrest frame 205 and the upper armrest frame 203 can be connected by screws or clips. The present application adopts a screw-fastening connection method. Specifically, mounting posts 214 are dispersed around the lower surface of the armrest frame 203. The mounting posts 214 are provided with internal threaded holes for screw connection. This not only ensures a firm installation, but also forms a support plane against the upper surface of the lower armrest frame 205 by the mounting posts 214. This can also avoid the problem of abnormal noise caused by large-scale direct contact between the lower armrest frame 205 and the upper armrest frame 203. In order to form surface-to-surface contact with the lower ends of the mounting posts 214, support cones are provided around the upper surface of the lower armrest frame 205, corresponding to each mounting post 214.

[0064] See also Figure 7 and Figure 8 In order to ensure the accuracy of the installation position of the armrest lower frame 205 and the armrest upper frame 203, positioning columns 207 are respectively provided at the front and rear ends of the upper surface of the armrest lower frame 205. At the same time, a positioning sleeve 208 that cooperates with the positioning column 207 is correspondingly provided on the lower surface of the armrest frame 203, and the positioning column 207 is inserted into the positioning sleeve 208.

[0065] A positioning structure is also provided between the flexible pad 201 of the present application and the armrest frame 203, see Figure 8 The positioning structure includes a positioning protrusion 213 provided on the lower surface of the flexible pad 201 and a positioning hole 212 provided on the armrest frame 203, and two positioning protrusions 213 are provided in the front and rear directions of the lower surface of the flexible pad 201 to form two-point accurate positioning.

[0066] The sliding handrail 20 further includes a handrail connecting plate 206, which is fixed to the lower surface of the handrail lower frame 205. A connecting rod passes through the handrail connecting plate 206 and the handrail lower frame 205 and is fastened with a nut. The connecting rod is a bolt or a double-headed screw.

[0067] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0068] Based on the same inventive concept, see Figure 14 and Figure 15 The present application also provides a seat structure including the aforementioned sliding armrest assembly. The sliding armrests 20 are disposed on the left and right sides of the seat frame. The supporting bases 10 in the sliding armrests 20 are secured to the left and right frames using screws and positioning posts 207, providing stable and reliable support for the sliding armrests 20.

[0069] In a third aspect, an embodiment of the present invention further provides a vehicle comprising the seat structure.

[0070] The seat structure and vehicle provided by the embodiment of the present invention, since they are equipped with the sliding armrest 20 that can move forward and backward, can not only improve the comfort of the driver and passengers, meet the diverse needs of different users in different scenarios, and improve user satisfaction, but also embody the humanization and high-end quality of the product, can attract more consumers' attention and purchases, bring more brand value to the car company, and enhance the market competitiveness of the car company.
