[0014] The seat according to the present invention has at least the following beneficial effects: by setting two control lines and two levers, it is only necessary to connect the transmission mechanisms on the seat that perform different functions to the two control lines respectively. Applying a first external force to the first driven part can control the locking or unlocking of the first transmission mechanism through the first control line, and applying a second external force to the second driven part can control the locking or unlocking of the second transmission mechanism through the second control line.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] To improve seat comfort, seats typically have multiple adjustment functions such as backrest recline and seat height adjustment. In existing technologies, the adjustment mechanisms are usually located near their respective transmission mechanisms and use structural forms such as operating handles. For example, the seat height adjustment mechanism is located at the bottom of the seat, and the backrest recline adjustment mechanism is located at the back of the seat. This results in poor integration and inconvenient operation.

[0026] This utility model proposes a control device 100, which can improve the integration and ease of operation of the control of the seat transmission mechanism.

[0027] According to a first aspect embodiment of the present invention, a control device 100 is used to control a first transmission mechanism and a second transmission mechanism of a seat, including a mounting base 101, a first lever 102, a first control line 103, a second lever 104, and a second control line 105. The mounting base 101 has a mounting cavity 106. The first lever 102 includes a first rotating part 107 and a first driven part 108. The first rotating part 107 is disposed within the mounting cavity 106 and is rotatable about a first axis 109. The first driven part 108 extends outward relative to the mounting cavity 106. The first control line 103 is connected at both ends to the first lever 102 and the first transmission mechanism, respectively. When the first driven part 108 is subjected to a first external force, the first control line 103 can move, thereby controlling the first transmission mechanism. The second lever 104 includes a second rotating part 110 and a second driven part 111. The second rotating part 110 is disposed in the mounting cavity 106 and can rotate around the first axis 109. The second driven part 111 extends outward relative to the mounting cavity 106. The two ends of the second control line 105 are respectively connected to the second lever 104 and the second transmission mechanism. When the second driven part 111 is subjected to a second external force, the second control line 105 can be moved to control the second transmission mechanism. By setting two control lines and two levers, the transmission mechanisms on the seat that perform different functions only need to be connected to the two control lines respectively. Applying a first external force to the first driven part 108 can control the locking or unlocking of the first transmission mechanism through the first control line 103, and applying a second external force to the second driven part 111 can control the locking or unlocking of the second transmission mechanism through the second control line 105. The control of two different transmission mechanisms is integrated into the same control device 100, which has higher integration. The wired control form makes it easy to adjust the position of the control device 100, so that the user only needs to control different transmission mechanisms from one position. Moreover, the operation of the lever is more convenient than the operation of existing technology such as the operating lever.

[0028] refer to Figure 1 and Figure 2 In some embodiments of this utility model, the first rotating part 107 and the second rotating part 110 are axially distributed along the first axis 109, and the directions of the first external force and the second external force are perpendicular to the first axis 109. This design can further improve the space utilization within the control device 100, making the structure more compact. In terms of operation, the user only needs to move the first driven part 108 and the second driven part 111. Since the first rotating part 107 and the second rotating part 110 are axially distributed along the first axis 109, the first external force and the second external force are also less strenuous.

[0029] In some embodiments of this utility model, the control device 100 includes a first elastic element (not shown in the figure), one end of which abuts against the mounting base 101, and the other end abuts against the first rotating part 107. When the first rotating part 107 rotates around the first axis 109, the elastic force of the first elastic element drives the first rotating part 107 to reset. Alternatively, the control device 100 includes a second elastic element (not shown in the figure), one end of which abuts against the mounting base 101, and the other end abuts against the second rotating part 110. When the second rotating part 110 rotates around the first axis 109, the elastic force of the second elastic element drives the second rotating part 110 to reset. The arrangement of the first and second elastic elements enables the first rotating part 107 and the second rotating part 110 to have an automatic reset function, eliminating the need for frequent adjustments. External force is applied during adjustments, and when no adjustments are needed, the external force is removed and the first lever 102 and the second lever 104 automatically reset, making it more convenient. It should be noted that in some embodiments of this utility model, the first and second elastic elements are torsion springs, which can be better positioned within the mounting cavity 106.

[0030] refer to Figure 2 and Figure 3 In some embodiments of this utility model, the first rotating part 107 is provided with a first gear slot 304 and a second gear slot 305 spaced apart along the circumference. The control device 100 also includes a limiting component 301, which is disposed in the mounting cavity 106. The limiting component 301 can abut against the first gear slot 304 or the second gear slot 305 to fix the first rotating part 107 relative to the mounting base 101. This enables the first lever 102 and its connected first control line 103 to have a gear adjustment function. For example, in some embodiments, the first transmission component is used to control the backrest tilt of the seat, while the first control line 103 is used to adjust the state of the first transmission component. When the limiting component 301 abuts against the first gear slot 304, the first control line 103 causes the first transmission component to be in an unlocked state, allowing the seat back to tilt freely. When the limiting component 301 abuts against the second gear slot 305, the first control line 103 causes the first transmission component to be in a locked state, fixing the backrest tilt angle. This provides both locked and free tilting options for the seat back. Specifically, the first control line 103 can adjust the state of the first transmission component by setting a locking element, such as a locking pin. The first control line 103 pulls the locking element to lock or unlock the first transmission component. The control device 100 of this embodiment can be applied to various transmission structures.

[0031] refer to Figures 3 to 5In some embodiments of this utility model, the limiting component 301 includes a third elastic member 302 and a locking block 303. The two ends of the third elastic member 302 abut against the mounting cavity 106 and the locking block 303, respectively. The elastic force of the third elastic member 302 is used to drive the locking block 303 closer to the first rotating part 107. The structure of the third elastic member 302 and the locking block 303 can better adapt to the structure within the mounting cavity 106, and refer to... Figure 3 In some embodiments, the mounting cavity 106 is further provided with a groove for accommodating the third elastic member 302 and the locking block 303. When the first rotating part 107 rotates to adjust the gear, the protrusion between the first gear slot 304 and the second gear slot 305 abuts against the locking block 303, causing the third elastic member 302 to be compressed. After the gear is adjusted, the elastic force of the third elastic member 302 causes the locking block 303 to abut against the first gear slot 304 or the second gear slot 305 to achieve gear shifting.

[0032] It should be noted that in some embodiments of this utility model, the limiting component 301 may also be a pin or a wave-shaped damping structure with elasticity.

[0033] refer to Figure 1 In some embodiments of this utility model, the control device 100 includes a first wire sleeve 114 and a first locking assembly 115. A first control line 103 is slidably threaded through the first wire sleeve 114, and the first wire sleeve 114 is detachably connected to the mounting base 101 via the first locking assembly 115. For example... Figure 1 As shown, to facilitate the installation of the first control line 103 and the first lever 102 on the mounting base 101, the mounting base 101 is provided with multiple openings, allowing the first control line 103 to be inserted into the openings and the first rotating part 107 to be directly placed into the mounting cavity 106. Therefore, the design of the first wire sleeve 114 and the first locking assembly 115 can prevent the first control line 103 from falling off the mounting base 101 due to reciprocating sliding or deformation at both ends during the operation of the first lever 102, thus improving the stability of the structure. Further, refer to... Figure 1 In some embodiments, the second control line 105 is also provided with a second wire sleeve 116, and the second wire sleeve 116 is detachably connected to the mounting base 101 via a second locking assembly 117, wherein the first locking assembly 115 can be used as follows: Figure 1 The structure shown uses a double-nut spaced arrangement to tighten the first wire sleeve 114 onto the protrusion of the mounting base 101, and the second locking assembly 117 can be used as follows: Figure 1As shown, two nuts are tightened side by side to hold the second wire sleeve 116 against the mounting base 101. The two locking methods can be interchanged. When the transmission mechanism to which one end of the first control line 103 or the second control line 105 is connected has tension, the second method can be used. When the connection position is the shift lock pin of the transmission mechanism, and the lock pin will exert a resisting and compressing force on the control line during the shifting process, making the control line easy to deform, the first locking method can be used to ensure that the control line is firmly connected to the mounting base 101.

[0034] refer to Figure 1 , Figure 4 and Figure 5 In some embodiments of this utility model, the first rotating part 107 is provided with a first guide groove 112 along the circumferential direction. When the first rotating part 107 rotates, at least a portion of the first control line 103 is embedded in the first guide groove 112; and / or, the second rotating part 110 is provided with a second guide groove 113 along the circumferential direction. When the second rotating part 110 rotates, at least a portion of the second control line 105 is embedded in the second guide groove 113. The first guide groove 112 and the second guide groove 113 can improve space utilization and prevent the first control line 103 and the second control line 105 from getting tangled around the outer periphery of the first rotating part 107 and the second rotating part 110 and occupying more space. On the other hand, they can also ensure that the first control line 103 and the second control line 105 can be more stably connected to the first rotating part 107 and the second rotating part 110, and prevent the control lines from getting tangled during rotation.

[0035] refer to Figures 4 to 6 In some embodiments of this utility model, a first limiting block is provided in the mounting cavity 106, and a first limiting groove 502 is provided in the first rotating part 107 along the circumferential direction. The end of the first limiting block away from the mounting cavity 106 is located in the first limiting groove 502. When the first rotating part 107 rotates, the first limiting block slides in the first limiting groove 502; and / or, a second limiting block 501 is provided in the mounting cavity 106, and a second limiting groove 401 is provided in the second rotating part 110 along the circumferential direction. The end of the second limiting block 501 away from the mounting cavity 106 is located in the second limiting groove 401. When the second rotating part 110 rotates, the second limiting block 501 slides in the second limiting groove 401. When the first rotating part 107 rotates to a certain extent, the side walls at both ends of the first limiting groove 502 will restrict the first limiting block, preventing the first lever 102 or the second lever 104 from rotating too much, and ensuring that the adjustment range of the control line is within a certain range. It should be noted that the reference Figure 6In some embodiments of this utility model, the first limiting groove 502, the first stop groove 304, and the first guide groove 112 are all distributed at intervals along the first axis 109 without interfering with each other, maximizing the utilization of the first rotating part 107. Similarly, the second limiting groove 401 and the second guide groove 113 on the second rotating part 110 are also designed to be non-interfering. It should be noted that the first limiting groove 502 and the second limiting groove 401, as well as the first limiting block and the second limiting block 501, are symmetrically designed. Figures 4 to 6 That is, the position design of the first limit block can be known.

[0036] The seat according to a second aspect embodiment of the present invention includes a control device 100 according to any one of the first aspect embodiments. By setting two control lines and two levers, the transmission mechanisms on the seat used to achieve different functions only need to be connected to the two control lines respectively. Applying a first external force to the first driven part 108 can control the locking or unlocking of the first transmission mechanism through the first control line 103, and applying a second external force to the second driven part 111 can control the locking or unlocking of the second transmission mechanism through the second control line 105. The control of two different transmission mechanisms is integrated into the same control device 100, which has higher integration. Moreover, the operation of the lever is more convenient than the operation of the existing lever structure. The seat using the control device 100 can effectively improve the user experience.

[0037] In some embodiments of this utility model, the seat includes a base, a seat cushion, a backrest, a first transmission mechanism, and a second transmission mechanism. The first transmission mechanism is connected to the base and the backrest, and the second transmission mechanism is connected to the seat cushion and the base. Both the first and second transmission mechanisms have locked and unlocked states. When the first control line 103 is driven by the first lever 102, the first transmission mechanism switches between the locked and unlocked states. When the second control line 105 is driven by the second lever 104, the second transmission mechanism switches between the locked and unlocked states. Thus, the first transmission mechanism enables the backrest to recline relative to the base, and the second transmission mechanism enables the seat cushion to rise or fall relative to the base. The control device 100 can switch the states of the transmission mechanisms to control both functions of the seat. In some embodiments of this utility model, the first and second transmission mechanisms can also be applied to multiple positions on the seat, such as the rotation of the lumbar support and the headrest, making them suitable for various scenarios.

[0038] In some embodiments of this utility model, the seat also includes armrests, with the mounting base 101 mounted on the bottom surface of the armrest or on the bottom surface of the base. This allows the mounting base 101 to be hidden in an infrequently used location on the seat, improving aesthetics, and the bottom surface of the armrest or the bottom surface of the base are commonly used control positions, enhancing the user's control experience.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
