[0039] In the technical solution of the utility model, the seat cushion 101 is connected to the lifting fitting 102, the base 105 is connected to the lifting mechanism 106, and the lifting mechanism 106 is detachably connected to the lifting fitting 102, so that the base 105 and the seat cushion 101 are detachably connected. During transportation, the base 105 and the seat cushion 101 can be transported and packaged separately, and the lateral volume of the seat 100 is reasonably allocated, so that the space occupied by the seat 100 in the lateral space is reduced, and the space occupancy is reasonable, which is convenient for packaging and can also reduce a certain packaging cost, and occupy space as reasonably as possible. Secondly, the pedal ring part 109 is detachably connected to the lifting fitting 102. During transportation, the pedal ring part 109 can be packaged and transported separately, and the longitudinal volume of the seat 100 is reasonably allocated, which reduces the difficulty of packaging and facilitates transportation. Furthermore, the seat 100 includes the seat cushion 101, the base 105 and the pedal ring part 109, the number of parts to be disassembled is reasonable, the structure is simple, and the installation is convenient.

[0040] In some embodiments, the lifting fitting 102 is detachably connected to the cushion 101. For the convenience of transportation and packaging. In this embodiment, the lifting fitting 102 is first installed and fixed together with the cushion 101 before packaging and transportation, and then the lifting fitting 102 is packaged and transported together with the cushion 101. On the one hand, it can simplify the installation steps of the user and provide a user experience. On the other hand, it can reduce the number of packages and save costs. In another embodiment, during the packaging process, the lifting fitting 102 and the cushion 101 are split structures, and the two are packaged independently and placed in different packaging boxes for packaging. This arrangement reasonably allocates the volume, ensures the rationality of the packaging volume, and facilitates transportation.

[0041] In some embodiments, the lifting mechanism 106 is detachably connected to the base 105. For the convenience of transportation and packaging. In this embodiment, before packaging and transportation, the lifting mechanism 106 and the base 105 are first fixed together, and then the lifting mechanism 106 and the base 105 are packaged and transported together. On the one hand, it can simplify the installation steps of the user and provide a user experience. On the other hand, it can reduce the number of packages and save costs. In another embodiment, the lifting mechanism 106 and the base 105 are split structures, and the two are packaged separately and placed in different packaging boxes for packaging. This arrangement reasonably allocates the volume of the components, ensures the rationality of the packaging volume, and facilitates transportation.

[0042] In some embodiments, the specific type of the lifting fitting 102 is not limited, as long as it can achieve the supporting function. For example, the lifting fitting 102 can be a support rod, a sleeve, a solid rod, etc. Considering the transportation cost and other issues, the lifting fitting 102 is selected as a sleeve. The interior of the sleeve is hollow, which is light, easy to transport, and has low transportation cost. Similarly, the specific type of the lifting mechanism 106 is not limited, as long as it can achieve lifting. For example, the lifting mechanism 106 can be a gas rod, an electric rod, or a hydraulic rod. In this embodiment, the lifting mechanism 106 is a gas rod. Compared with the electric rod, the electric rod needs to be charged after working for a period of time, and the gas rod does not need to be charged, which is more convenient to use; compared with the hydraulic rod, the hydraulic rod is lifted and lowered by hydraulic pressure, and the hydraulic rod is filled with lubricating oil, which is easy to seep out, and the experience is poor.

[0043] For further information, see Figure 3 The lifting mechanism 106 includes a gas rod, which includes a fixed portion 116 and a telescopic portion 117. The fixed portion 116 is connected to the base 105, and the telescopic portion 117 is movably connected to the side of the fixed portion 116 away from the base 105. The telescopic portion 117 extends into the sleeve and is connected to the seat cushion 101 or the sleeve. In this embodiment, the fixed portion 116 is fixedly connected to the base 105, and the telescopic portion 117 is connected to the seat cushion 101 or the sleeve. When the seat 100 needs to be raised, the telescopic portion 117 moves in a direction away from the fixed portion 116, driving the seat cushion 101 or the sleeve to move in a direction away from the base 105, thereby raising the height of the seat 100. When the seat 100 needs to be lowered, the telescopic portion 117 moves in a direction close to the fixed portion 116, driving the seat cushion 101 or the sleeve to move in a direction close to the base 105, thereby lowering the height of the seat 100.

[0044] In some embodiments, see Figure 4 The pedal ring portion 109 includes a pedal ring 110 and a connecting piece 111. The pedal ring 110 is fixedly connected to the connecting piece 111. The pedal ring 110 extends to a side away from the connecting piece 111. The connecting piece 111 is sleeved on the lifting fitting 102, and the connecting piece 111 is detachably connected to the lifting fitting 102. The pedal ring 110 and the connecting piece 111 are integrally formed. The specific shape of the pedal ring 110 is not limited and can be designed according to actual conditions (customer needs, etc.). For example, the shape of the pedal ring 110 can be circular, elliptical, irregularly circular, triangular, square, etc.

[0045] See also Figure 4 and Figure 5 The main function of the footrest ring 110 is to support the user's feet so that the user is in a more comfortable state. Therefore, when the user uses the chair 100, when the user's feet are placed on the footrest ring 110, a downward force will be applied to the footrest ring 110. In order to prevent the footrest ring 110 from moving, the footrest ring portion 109 also includes a first limiting portion 112, which is sleeved on the lifting mechanism 106. The first limiting portion 112 is located on the side of the connecting member 111 close to the base 105, and the side of the connecting member 111 close to the base 105 abuts against the first limiting portion 112. In this embodiment, the first limiting portion 112 is arranged below the connecting member 111 and abuts against the connecting member 111. When the user uses the chair 100 and applies a downward force to the footrest ring 110, the first limiting portion 112 supports the connecting member 111 to prevent the connecting member 111 from moving downward.

[0046] Furthermore, the specific structure of the first limiting portion 112 is not limited, as long as it can achieve the limiting support function; in one embodiment, please continue to refer to Figure 5 The first limiting portion 112 includes a connecting portion 113 and a blocking portion 114 that are connected to each other; wherein, one end of the connecting member 111 that is away from the seat cushion 101 is sleeved on the connecting portion 113, and the end surface of the connecting member 111 that is away from the seat cushion 101 abuts against the blocking portion 114. It should be noted that the connecting portion 113 is connected to the connecting member 111, and the blocking portion 114 is arranged below the connecting member 111 and abuts against the connecting member 111. The first limiting portion 112 provided in this embodiment is first connected to the connecting member 111 through the connecting portion 113 to fix the first limiting portion 112 to the connecting member 111. The connecting portion 113 can disperse part of the force applied by the user. At the same time, the blocking portion 114 is arranged below the connecting member 111 to support the connecting member 111. The connecting portion 113 and the blocking portion 114 cooperate to fix the connecting member 111 on the lifting fitting 102.

[0047] It should be noted that the main function of the footrest ring 110 is to support the user's feet so that the user is in a relatively comfortable state when using the chair 100. Therefore, the position of the footrest ring 110 needs to be ergonomic. Therefore, the position of the footrest ring 110 needs to be fixed, so that it can move upward and cannot fall down. Specifically, in this embodiment, please refer to Figure 6The pedal ring portion 109 also includes a second limiting portion 115, which is sleeved on the lifting fitting 102, and the second limiting portion 115 is located on a side of the connecting member 111 close to the seat cushion 101, and a side of the connecting member 111 close to the seat cushion 101 abuts against the second limiting portion 115.

[0048] Furthermore, during the installation of the pedal ring portion 109, the second limiting portion 115 is first installed on the lifting fitting 102, and then the connecting member 111 is installed on the lifting fitting 102 until the upper side of the connecting member 111 abuts against the second limiting portion 115. At this time, the first limiting portion 112 is installed on the lifting fitting 102. In this way, the first limiting portion 112 and the second limiting portion 115 cooperate with each other to fix the connecting member 111.

[0049] In some embodiments, see Figure 7 In order to reduce the number of packages, the second limiting portion 115 can be installed on the lifting fitting 102 before transportation, so that the second limiting portion 115 and the lifting fitting 102 are transported together. Figure 7 In this way, the packaging of the second limiting portion 115 can be omitted, and the user can also save the installation steps of installing the second limiting portion 115. The user does not need to install and fix the second limiting portion 115, and only needs to install the connecting member 111 and the first limiting portion 112 according to the operating steps.

[0050] In some embodiments, see Figure 8 Before transportation, the first limiting portion 112 is installed on the connecting member 111. Figure 8 In this way, the packaging of the first limiting part 112 can be omitted, and the user can also omit the installation step of the first limiting part 112 during assembly, and directly install the connecting member 111 and the first limiting part 112 on the lifting fitting 102 at the same time, thereby simplifying the installation steps and improving the user experience.

[0051] The connection method between the connecting piece 111 and the lifting fitting 102 is not limited, and can be riveted, threaded, or clamped, depending on the actual situation. Considering the convenience of guarantee and transportation, the connecting piece 111 provided in this application is detachably connected to the lifting fitting 102, so in order to facilitate the user's assembly and installation, please refer to Fig. 9In this embodiment, the connecting member 111 is threadedly connected to the lifting fitting 102. A first external thread is formed on the outer surface of the lifting fitting 102 at one end close to the lifting structure, and a first through hole is formed on the connecting member 111. A first internal thread is formed on the inner hole wall of the first through hole. The first external thread cooperates with the first internal thread to fix the connecting member 111 on the lifting fitting 102.

[0052] For further information, please refer to Fig. 9 The length of the first external thread is L1, and the length of the first internal thread is L2, wherein L1 = L2. This arrangement facilitates the operator to perform installation and alignment.

[0053] In some embodiments, the second position-limiting portion 115 is threadedly connected to the lifting fitting 102. The second position-limiting portion 115 is formed with a third through hole, and a second internal thread is formed on the inner hole wall of the third through hole. The second internal thread cooperates with the first external thread to fix the first position-limiting portion 112 on the lifting fitting 102.

[0054] For further information, please refer to Fig. 9 , the length of the second internal thread is L3, where L3=0.4L1. It should be noted that the length of the second internal thread should not be too long, otherwise it will affect the fixation of the connecting member 111. The length of the second internal thread should not be too short, otherwise the fixation will be unstable, the connecting member 111 will easily shake, and the user experience will be reduced.

[0055] In some embodiments, the first limiting portion 112 is threadedly connected to an end of the connecting member 111 away from the second limiting portion 115. Specifically, a second external thread is formed on the outer surface of the connecting portion 113, and the second external thread cooperates with the first internal thread to fix the first limiting portion 112 and the connecting member 111, and the blocking portion 114 abuts against the bottom of the connecting member 111.

[0056] For further information, please refer to Fig. 9 , the length of the second external thread is L4, where L4=0.4L1, and L4=L3. The length of the second external thread should not be too long or too short. When the length of the second external thread is long enough, the size of the connecting member 111 needs to be increased accordingly, resulting in an increase in the size of the pedal ring portion 109 and an increase in the occupied space. When the size of the second external thread is too short, the connection between the connecting portion 113 and the connecting member 111 is unstable, resulting in the pedal ring 110 being easy to shake and the user experience being reduced.

[0057] For further information, please refer to Fig. 9During the actual installation process, the second limiting portion 115 is first installed on the lifting fitting 102. Due to the cooperation between the second internal thread and the first external thread, the second limiting portion 115 rotates along the rotation direction of the first external thread until the second limiting portion 115 cannot move. At this time, the limiting portion is fixed on the lifting fitting 102. Then install the connecting piece 111 on the lifting fitting 102. Due to the cooperation between the first internal thread and the first external thread, the connecting piece 111 rises along the rotation direction of the first external thread. When the connecting piece 111 abuts against the second limiting portion 115, the connecting piece 111 cannot continue to rise, thereby fixing the connecting piece 111 on the lifting fitting 102. Since the length of the second internal thread is the same as the length of the first external thread, part of the thread of the first external thread cooperates with the second internal thread. At this time, part of the second internal thread is vacant and does not cooperate with any thread. Then, the connecting portion 113 is cooperated with the connecting piece 111, and the second external thread cooperates with the first internal thread. The connecting piece 111 rises along the rotation direction of the first internal thread until the blocking portion 114 abuts against the connecting piece 111. At this time, the first limiting portion 112 is fixed to the connecting piece 111, and the first limiting portion 112 cooperates with the second limiting portion 115 to fix the connecting piece 111. It should be noted that the threaded connection method is simpler, does not involve complicated parts connection relationships, and is also easier for users during the assembly process.

[0058] See also Fig. 9 and Fig.10 , the first external thread has a fifth end close to the seat cushion 101 and a sixth end away from the seat cushion 101, the sixth end is flush with the second end 104, and the length of the lifting fitting 102 is L5, wherein L5:L1=1:(0.08-0.1), that is, the length of the first external thread is 0.08-0.1 times the length of the lifting fitting 102. When the ratio of the length of the first external thread to the length of the lifting fitting 102 is less than 0.08, the length of the first external thread is too short, the connection between the pedal ring 109 and the lifting fitting 102 is unstable, and when the user uses the pedal ring 110, the pedal ring 110 is easy to shake or even fall off, and the user experience is poor. When the ratio of the length of the first external thread to the length of the lifting fitting 102 is greater than 0.1, the length of the first external thread is too long, causing the position of the pedal ring 109 to shift upward as a whole, which is not ergonomic. The user will feel obvious resistance when using the pedal ring 110, and the user experience is poor.

[0059] Furthermore, according to ergonomic design, the height of the seat cushion 101 is H0, wherein 80mm≤H0≤160mm. More specifically, the height of the seat cushion 101 is 80mm, 85mm, 90mm, 95mm, 100mm, 105mm, 110mm, 115mm, 120mm, 125mm, 130mm, 135mm, 140mm, 145mm, 150mm, 155mm, and 160mm. The distance between the fifth end and the first end 103 is L6, 310m≤L6≤390mm. More specifically, the distance between the fifth end and the first end 103 can be 310mm, 315mm, 320mm, 325mm, 330mm, 335mm, 340mm, 345mm, 350mm, 355mm, 360mm, 365mm, 370mm, 375mm, 380mm, 385mm, or 390mm.

[0060] In some embodiments, the seat cushion 101 has a first end 103 surface away from the base 105, the base 105 has a second end 104 surface away from the seat cushion 101, the vertical distance between the first end 103 surface and the second end 104 surface is H1, the sum of the heights of the seat cushion 101 and the lifting fitting 102 is H2, the lifting mechanism 106 has a fixed portion 116 and a telescopic portion 117, the fixed portion 116 is fixedly connected to the base 105, and the sum of the heights of the fixed portion 116 and the base 105 is H3, wherein H1:H3=(2.5-3):1, and / or, H2:H3=(1.5-2.5):1. It should be noted that H2 and H3 should not be too large or too small. Within the above range, the rationality of the layout of the seat 100 can be ensured, and it is convenient to ensure and transport.

[0061] Furthermore, the seat cushion 101 has a first end 103 surface facing away from the base 105, and the base 105 has a second end 104 surface facing away from the seat cushion 101, and the vertical distance between the first end 103 surface and the second end 104 surface is H1, wherein 550mm≤H1≤800mm. It should be noted that the vertical distance between the first end 103 surface and the second end 104 surface is the overall height of the seat 100. When the vertical distance between the first end 103 surface and the second end 104 surface is less than 550mm, the overall size of the seat 100 is small and cannot meet the needs of normal users. When the vertical distance between the first end 103 surface and the second end 104 surface is greater than 800mm, the size of the seat 100 is too large, and the packaging and transportation costs increase.

[0062] In some embodiments, the sum of the heights of the seat cushion 101 and the lifting fitting 102 is H2, wherein 380 mm ≤ H2 ≤ 480 mm. When the sum of the heights of the seat cushion 101 and the lifting fitting 102 is less than 3800 mm, the height of the lifting fitting 102 is relatively small, and when the lifting fitting 102 is matched with the tread ring 109, the size of the tread ring 109 is too large, and the user has obvious discomfort in the legs when using the tread ring 109. When the sum of the heights of the seat cushion 101 and the lifting fitting 102 is greater than 480 mm, the length of the lifting fitting 102 and the seat cushion 101 is too long, the space occupied increases, and the transportation cost increases. Specifically, the sum of the heights of the seat cushion 101 and the lifting fitting 102 is 380mm, 385mm, 390mm, 395mm, 400mm, 405mm, 410mm, 415mm, 420mm, 425mm, 430mm, 435mm, 440mm, 445mm, 450mm, 455mm, 460mm, 465mm, 470mm, 475mm, and 480mm.
