[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, with reference to the accompanying drawings, the preferred embodiments of the present utility model will be described in detail.

[0033] Referring to Figure 1 and Figure 2 , an embodiment of the present utility model provides a seat 1000, asFigure 1 As shown, the seating device 1000 includes an axilla support assembly 100, a seat cushion 200, and a lumbar support 300. The axilla support assembly 100, the lumbar support 300, and the seat cushion 200 are sequentially arranged in the gravity direction (such as the X direction shown). Figure 1 Among them, the axilla support assembly 100 is movably connected to the seat cushion 200 in the gravity direction to adjust the height of the axilla support assembly 100. The axilla support assembly 100 includes two support arms 110 spaced apart in the first direction (such as the Y direction shown). Figure 1 The two support arms 110 are movably connected to the seat cushion 200 in the first direction to adjust the distance between the two support arms 110.

[0034] Specifically, in this embodiment, since the axilla support assembly 100 is movably connected to the seat cushion 200 in the gravity direction, the relative position of the axilla support assembly 100 can be adjusted in the gravity direction, thereby adjusting the height of the axilla support assembly 100; since the axilla support assembly 100 includes two support arms 110 spaced apart in the first direction, the two support arms 110 can be used to support the armpits on the left and right sides of the user. Also, because the two support arms 110 are movably connected to the seat cushion 200 in the first direction, the distance between the two support arms 110 is adjustable. Thus, it can be seen that the height and width of the axilla support assembly 100 of the seating device 1000 in this embodiment are both adjustable, so it can well adapt to consumers with different body shapes and has good versatility. The seating device 1000 in this embodiment can be placed on the seat and removed from the seat, which is very flexible and convenient.

[0035] Referring to Figure 1 、 Figure 2 , in a specific embodiment, the seating device 1000 includes a main rod 400. The main rod 400 includes a first telescopic section 410 and a second telescopic section 420. The first telescopic section 410 and the second telescopic section 420 are sleeved with each other so that the second telescopic section 420 can move relative to the first telescopic section 410. The seat cushion 200 is connected to the first telescopic section 410, and the axilla support assembly 100 is connected to the second telescopic section 420.

[0036] Specifically, since the second telescopic section 420 can move relative to the first telescopic section 410, and the seat cushion 200 and the axilla support assembly 100 are respectively connected to the first telescopic section 410 and the second telescopic section 420, the axilla support assembly 100 can move relative to the seat cushion 200 in the gravity direction.

[0037] It should be noted that the first telescopic joint 410 and the second telescopic joint 420 are nested, which includes both the first telescopic joint 410 being nested in the second telescopic joint 420 and the second telescopic joint 420 being nested in the first telescopic joint 410, which is not limited in this embodiment. In a specific embodiment, the top of the first telescopic joint 410 has a first narrowing section 411, and the second telescopic joint 420 is nested in the first narrowing section 411. In another specific embodiment, the first telescopic joint 410 is thicker or thinner than the second telescopic joint 420.

[0038] In a specific embodiment, the main rod 400 further includes a first locking structure, which is disposed on the first telescopic joint 410 and the second telescopic joint 420 to lock the first telescopic joint 410 and the second telescopic joint 420 .

[0039] Specifically, if the first telescopic section 410 and the second telescopic section 420 cannot be forcibly locked, after the user adjusts the height of the armpit support assembly 100 as required, the armpit support assembly 100 may slide down due to external force, affecting the user experience. In order to solve this technical problem, the main rod 400 of this embodiment also includes a first locking structure, which is arranged on the first telescopic section 410 and the second telescopic section 420. The user can use the first locking structure to lock the first telescopic section 410 and the second telescopic section 420 to prevent the second telescopic section 420 from moving relative to the first telescopic section 410 after adjusting the armpit support assembly 100, thereby preventing the armpit support assembly 100 from sliding down due to external force.

[0040] It is worth mentioning that there are many specific implementations of the first locking structure, so this embodiment is not limited here. Several embodiments are listed below for illustration:

[0041] refer to Figure 3 In the first embodiment, the first locking structure includes a first elastic positioning member 430 and a plurality of first positioning holes. The plurality of first positioning holes are arranged on the first telescopic joint 410 in the direction of gravity. The first elastic positioning member 430 is installed on the second telescopic joint 420. The first elastic positioning member 430 is used to pass through the first positioning hole when releasing energy, and to be able to detach from the first positioning hole when under pressure.

[0042] refer to Figure 3 In the second embodiment, the first locking structure includes a first elastic positioning member 430 and a plurality of first positioning holes. The plurality of first positioning holes are arranged on the second telescopic joint 420 in the direction of gravity. The first elastic positioning member 430 is installed on the first telescopic joint 410. The first elastic positioning member 430 is used to pass through the first positioning hole when releasing energy, and to be able to detach from the first positioning hole when under pressure.

[0043] refer to Figure 3, in the specific embodiments of the first embodiment and the second embodiment, the first elastic positioning member 430 includes a first mounting shell 431, a first spring 432 and a first movable block 433. The first mounting shell 431 has a first accommodating groove 4311. The first movable block 433 is installed in the first accommodating groove 4311. The first spring 432 is clamped between the first movable block 433 and the bottom of the first accommodating groove 4311. The first movable block 433 can at least partially penetrate out of the first accommodating groove 4311 driven by the first spring 432, so that the first movable block 433 can penetrate into the first positioning hole. When the first movable block 433 is pressed, the first spring 432 will be compressed and store energy, so that the first movable block 433 can disengage from the first positioning hole.

[0044] In the third embodiment, the first locking structure is a first friction plate clamped between the first telescopic section 410 and the second telescopic section 420, and the first telescopic section 410 and the second telescopic section 420 are locked by increasing the friction force.

[0045] In the fourth embodiment, the first locking structure includes a first jack, a first bolt and a plurality of second jacks. The first jack is arranged on the first telescopic section 410. The plurality of second jacks are arranged on the second telescopic section 420 in the direction of gravity. When the first bolt is inserted into the first jack and the second jacks, the first telescopic section 410 and the second telescopic section 420 can be locked. The first bolt is adapted to different second jacks, so as to adjust the length of the main rod 400.

[0046] Reference Figure 1 、 Figure 2 , in some embodiments, the seat 1000 further includes two third telescopic sections 500. One ends of the two third telescopic sections 500 are respectively connected to both sides of the second telescopic section 420 in the first direction. The axillary support assembly 100 further includes two fourth telescopic sections 120. The two fourth telescopic sections 120 are respectively sleeved with the two third telescopic sections 500, so that the fourth telescopic section 120 can move relative to the third telescopic section 500. The two support arms 110 are respectively connected to the two fourth telescopic sections 120.

[0047] Specifically, since the fourth telescopic section can move relative to the third telescopic section 500, and because the support arm 110 is connected to the fourth telescopic section 120, and the seat cushion 200 is connected to the third telescopic section 500 through the first telescopic section 410 and the second telescopic section 420, the support arm 110 can move relative to the seat cushion 200 in the first direction.

[0048] It should be noted that the third telescopic section 500 and the fourth telescopic section 120 are sleeved with each other, which includes both the third telescopic section 500 being sleeved on the fourth telescopic section 120 and the fourth telescopic section 120 being sleeved on the third telescopic section 500. This embodiment does not make a limitation here. In a specific embodiment, the side of the fourth telescopic section 120 away from the support arm 110 has a second narrowing section 121, and the third telescopic section 500 is sleeved on the second narrowing section 121. In another specific embodiment, the third telescopic section 500 is thicker or thinner than the fourth telescopic section 120.

[0049] It is worth mentioning that since the third telescopic section 500 and the fourth telescopic section 120 are sleeved with each other, the third telescopic section 500 and the fourth telescopic section 120 can be separated, which enables the armpit support assembly 100 to be disassembled separately for easy storage and transportation.

[0050] In a specific embodiment, the seat 1000 further includes a second locking structure, which is arranged on the third telescopic section 500 and the fourth telescopic section 120 to lock the third telescopic section 500 and the fourth telescopic section 120 in the first direction.

[0051] Specifically, if the third telescopic section 500 and the fourth telescopic section 120 cannot be forcibly locked, after the user adjusts the distance between the two support arms 110 according to the needs, the distance between the two support arms 110 may be affected by external forces and change, affecting the user experience. To solve this technical problem, the main rod 400 of this embodiment further includes a second locking structure, which is arranged on the third telescopic section 500 and the fourth telescopic section 120. The user can use the second locking structure to lock the third telescopic section 500 and the fourth telescopic section 120, avoiding the situation where the fourth telescopic section 120 moves relative to the third telescopic section 500 after adjusting the distance between the two support arms 110, and further avoiding the situation where the distance between the two support arms 110 may be affected by external forces and change.

[0052] It is worth mentioning that there are many specific implementation manners of the second locking structure, so this embodiment does not make a limitation here. The following lists several embodiments for illustration:

[0053] Reference Figure 3 , in the first embodiment, the second locking structure includes a second elastic positioning member 600 and a plurality of second positioning holes. The plurality of second positioning holes are arranged on the third telescopic section 500 in the first direction. The second elastic positioning member 600 is installed on the fourth telescopic section 120. The second elastic positioning member 600 is used to penetrate the second positioning holes when releasing energy and can disengage from the second positioning holes when being pressed.

[0054] Reference Figure 3, in the second embodiment, the second locking structure includes a second elastic positioning member 600 and a plurality of second positioning holes. The plurality of second positioning holes are arranged on the fourth telescopic section 120 in the first direction. The second elastic positioning member 600 is installed on the third telescopic section 500. The second elastic positioning member 600 is configured to penetrate through the second positioning holes when releasing energy, and can disengage from the second positioning holes when being pressed.

[0055] In the specific embodiments of the first and second embodiments, the second elastic positioning member 600 includes a second mounting shell 610, a second spring 620 and a second movable block 613. The second mounting shell 610 has a second accommodating groove 611. The second movable block 613 is installed in the second accommodating groove 611. The second spring 620 is clamped between the second movable block 613 and the bottom of the second accommodating groove 611. The second movable block 613 can at least partially penetrate out of the second accommodating groove 611 under the drive of the second spring 620, so that the second movable block 613 can penetrate into the second positioning holes. When the second movable block 613 is pressed, the second spring 620 will be compressed to store energy, so that the second movable block 613 can disengage from the second positioning holes.

[0056] In the third embodiment, the second locking structure is a second friction plate clamped between the third telescopic section 500 and the fourth telescopic section 120, and the third telescopic section 500 and the fourth telescopic section 120 are locked by increasing the friction force.

[0057] In the fourth embodiment, the second locking structure includes a third jack, a second bolt and a plurality of fourth jacks. The third jack is arranged on the third telescopic section 500. The plurality of fourth jacks are arranged on the fourth telescopic section 120 in the first direction. The first telescopic section 410 and the second telescopic section 420 can be locked by inserting the second bolt into the first jack and the second jack. By adapting the second bolt to different second jacks, the distance between the two support arms 110 can be adjusted.

[0058] Reference Figure 4 , in some embodiments, the two support arms 110 are respectively rotatably connected to the two fourth telescopic sections 120, and the rotation axes extend in the direction of gravity.

[0059] By implementing this embodiment, when the support arms 110 are not needed, the support arms 110 can be folded up by rotation, so as to achieve the technical effect of saving space.

[0060] Reference Figure 4 、 Figure 5 , in some embodiments, the seat 1000 further includes a damping rotating shaft (not shown in the figure). The seat cushion 200 is rotatably connected to the first telescopic section 410 through the damping rotating shaft, and the axis of the damping rotating shaft extends in the first direction.

[0061] By implementing this embodiment, the seat cushion 200 can rotate and fold relative to the main rod 400, thereby achieving the technical effect of saving space, which is beneficial to the storage and transportation of the seat 1000.

[0062] Reference Figure 4 、 Figure 5 In some specific embodiments, a rotating rod 700 is provided at the top of the seat cushion 200. One side of the rotating rod 700 away from the seat cushion 200 is rotatably connected to one end of the first telescopic section 410 through a damping rotating shaft, and the length of the rotating rod 700 is greater than the thickness of the lumbar support 300.

[0063] Since the length of the rotating rod 700 is greater than the thickness of the lumbar support 300, the seat cushion 200 will not interfere with the lumbar support 300 when folding.

[0064] In some embodiments, the lumbar support 300 is detachably connected to the first telescopic section 410 so that the lumbar support 300 can be detached. On the one hand, it is convenient for the user to decide whether to use the lumbar support 300 according to actual needs. On the other hand, it is convenient for the user to detach the lumbar support 300 for cleaning.

[0065] Furthermore, the lumbar support 300 can be detachably connected to the first telescopic section 410 by means of straps, Velcro, etc. This embodiment does not make a limitation here.

[0066] Reference Figure 1 、 Figure 2 In some embodiments, the seat 1000 further includes a headrest 800, and the headrest 800 and the axillary support assembly 100 are sequentially arranged in the direction of gravity. After the headrest 800 is provided, the seat 1000 can provide support for the user's head, further improving the riding comfort of the seat 1000.
