Abstract
Description
Technical Field
[0001] This utility model relates to the field of seat technology, specifically to a hand controller storage mechanism and a seat. Background Technology
[0002] Electric seats typically use a hand controller to control functions such as backrest tilt and height adjustment, aiming to provide users with a comfortable riding experience. As one of the components for operating seat functions, the installation and usage of the hand controller directly affect the overall practicality and user experience of the seat.
[0003] Currently, most power seat controllers are designed to be exposed, typically mounted on the seat cushion surface in a fixed manner or clipped to the edge of the cushion using a limiting structure. However, this design has significant drawbacks. On the one hand, the controller cannot be stored within the seat, and its long-term exposure makes it susceptible to damage from impacts and friction. It may also lead to accidental activation of seat functions, affecting safety. On the other hand, exposed controllers disrupt the overall aesthetics and harmony of the seat, and increase its overall volume during packaging and transportation, raising warehousing and logistics costs. Utility Model Content
[0004] The purpose of this utility model is to provide a hand controller storage mechanism for a seat and a seat, which realizes convenient storage and extension of the hand controller body through a first locking member and a second locking member that can be locked and released, saving the overall space occupied by the seat, improving the appearance coordination and operation comfort.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A hand controller storage mechanism, applied to a seat, comprising:
[0007] The fixed base is equipped with a first locking element;
[0008] The hand controller body is provided with a second locking member. The hand controller body is disposed on the fixed base and can move towards or away from the fixed base to be stored in the fixed base or extend from the fixed base.
[0009] The first locking member and the second locking member have a locked state and a released state; when the hand controller body moves to the position where it is housed in the fixed base, the first locking member and the second locking member can be locked to restrict the hand controller body from extending out of the fixed base; when the first locking member and the second locking member are in the released state, the hand controller body can move in the direction of extending out of the fixed base.
[0010] Preferred options also include:
[0011] An elastic element is disposed between the fixed base and the hand controller body;
[0012] The two ends of the elastic element act on the fixed base and the hand controller body respectively, so that the hand controller body tends to extend out of the fixed base.

[0019] The hand controller body is provided with a plurality of second guide structures, the second guide structures are positioned corresponding to the first guide structures, and each second guide structure is guided and cooperated with each of the first guide structures.
[0020] Preferably, both the first guide structure and the second guide structure are provided in pairs;
[0021] The first guide structure is configured as a guide rail, which includes a first limiting plate and a guide plate. Both first limiting plates are disposed on the fixed base and extend in the vertical direction. The guide plate is connected to the first limiting plate and is disposed at an angle. The two guide plates extend in directions away from each other. A guide groove is formed between the guide plate and the fixed base.
[0022] The second guide structure is configured as a slider, which is slidably disposed in the guide groove. Furthermore, a second limiting plate is disposed outside the guide groove and is opposite to the edge of the guide plate.
[0023] Preferably, the fixing base has a hollow receiving cavity, and one side of the fixing base has an opening communicating with the receiving cavity, and the first locking member is disposed in the receiving cavity;
[0024] The hand controller body is movably disposed in the receiving cavity through the opening, and the second locking member is disposed on the side of the hand controller body located inside the receiving cavity.
[0025] Preferably, the fixing base includes:
[0026] A base housing, wherein the receiving cavity is provided inside the base housing, and the opening is opened on one side of the base housing, the base housing is used to be installed in the seat cushion of the seat, and the receiving cavity is exposed to the outside of the seat cushion through the opening;
[0027] An outer buckle is detachably disposed on the base housing and surrounds the opening. When the base housing is installed inside the cushion, a portion of the outer buckle is disposed inside the cushion and another portion abuts against the surface of the cushion.
[0028] Preferably, of the first locking member and the second locking member, one is a male locking buckle and the other is a female locking buckle;

[0033] As described above, in the hand controller storage mechanism, the fixed base is disposed in the storage slot, and the hand controller body can be stored in the storage slot or extend out of the storage slot through the slot opening.
[0034] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0035] By engaging the first locking element of the fixed base with the second locking element of the hand controller body, locking (storage) and releasing (extend) can be achieved simply by operating in a preset manner (such as pressing, pulling, etc.), without any complicated operations. Compared with exposed or simply snap-fit hand controllers, this technical solution is easier to operate, especially suitable for users who have high requirements for ease of operation, significantly improving their comfort of use.
[0036] Secondly, the hand controller can be completely stored inside the fixed base (such as inside the seat cushion), avoiding the problem of exposed hand controllers occupying extra space, thereby effectively reducing the overall packaging volume of the seat, reducing packaging material costs, and facilitating warehousing, stacking, and transportation.
[0037] In its stowed state, the controller is housed within a fixed base (such as a seat cushion), creating a seamless and unified appearance between the controller storage mechanism and the seat cushion. This avoids the problem of exposed controllers disrupting the overall aesthetic harmony of the seat. Furthermore, once the controller is stowed within the fixed base, it remains stable thanks to the locking mechanism of the first and second locking elements. This reduces the risk of physical damage from collisions or friction caused by exposure, lowers the likelihood of accidental button presses during daily use, and enhances safety.

[0049] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0052] An electric seat is a type of seat that uses an electric adjustment device to achieve functions such as backrest tilt and height adjustment. It usually relies on a hand controller to complete various operations, aiming to provide users with a more comfortable riding experience. As a key component for operating the seat's functions, the installation and usage of the hand controller directly affect the overall practicality and user experience of the seat.
[0053] As can be seen from the background technology, most existing electric chair hand controllers are exposed and fixed to the seat cushion or secured to the seat cushion by a limiting clip. They are exposed to the outside of the seat cushion 60 for a long time, or they need to be removed when the hand controller is used, which makes them impossible to store and inconvenient to operate, affecting the packaging volume or appearance.
[0054] This embodiment provides a hand controller storage mechanism, which provides a first locking member 20 and a second locking member 40 between the fixed base 10 and the hand controller body 30, so that the hand controller body 30 can be stored in the seat cushion 60 through the fixed base 10, reducing the impact of the hand controller body 30 on the overall shape of the seat product, saving the space occupied by the product, facilitating user operation, and improving the user experience.
[0055] Please refer to the instruction manual attached. Figures 1-6 , Figures 9-10 The hand controller storage mechanism can be applied to seats (such as the seat cushion of an electric seat). It mainly includes a fixed base 10 and a hand controller body 30. The hand controller body 30 is disposed on the fixed base 10 and can move relative to the fixed base 10 to move in the direction close to or away from the fixed base 10, so as to realize the storage of the hand controller body 30 on the fixed base 10 (such as the seat cushion 60) or to extend out of the fixed base 10.
[0056] In this embodiment, the fixed base 10 serves as the mounting base for the hand controller storage mechanism. In actual seat applications, it can be fixed inside the seat cushion (such as in the pre-reserved storage slot 61 of the seat cushion). Its specific form can be designed according to the seat structure; for example, it can be an outer shell structure with a hollow cavity, or a frame 70 integrally formed with the seat cushion. The fixed base 10 is provided with a first locking member 20, which cooperates with the second locking member 40 on the hand controller body 30 to lock or release the hand controller body 30.
[0057] For example, the first locking member 20 may be, but is not limited to, a push-button female buckle, which can be snapped onto the inner wall or cavity edge of the fixed base 10; it may also be a buckle with elastic protrusion, a magnetic female seat, etc., as long as it can form a stable locking engagement with the second locking member 40.
[0058] The hand controller body 30 serves as the core component for user interaction with the electric seat. It typically integrates functional components such as a button panel and control panel, and is enclosed by a hand controller housing (e.g., a combination of an upper and lower housing) to form the hand controller body 30. Its overall shape can be designed as elongated, flat, etc., to fit the fixed base 10 and the seat structure. As described above, the hand controller body 30 is equipped with a second locking element 40 corresponding to the first locking element 20. This can be, for example, but is not limited to, a push-button male buckle, or a grooved snap fastener, magnetic male connector, etc., as long as it matches the first locking element 20.
[0059] In this embodiment, the hand controller body 30 can be mounted on the fixed base 10 via movable structures such as a sliding groove and slider, a guide rod and a guide hole, so that the hand controller body 30 can move along a preset trajectory (such as a horizontal direction) towards the fixed base 10 (to achieve storage) or move away from the fixed base 10 (to achieve extension). During this process, the cooperation of the first locking member 20 and the second locking member 40 determines the state of the hand controller body 30 and the fixed base 10. When the hand controller body 30 moves to the storage position (for example, completely entering the cavity of the fixed base 10 and hidden in the seat cushion), the first locking member 20 and the second locking member 40 are locked. For example, if the first locking member 20 is a female buckle and the second locking member 40 is a male buckle, the male buckle will engage in the groove of the female buckle, restricting the hand controller body 30 from sliding outward and ensuring its stable storage. When the user needs to use the hand controller, a force in a preset direction is applied to the hand controller body 30 (for example, to make the hand controller body 30 move further towards the fixed base 10). The pressure of 0 can also be a pulling force that moves the controller body 30 away from the fixed base 10, causing the first locking member 20 and the second locking member 40 to trigger the release mechanism (such as the elastic claw 21 of the female buckle opening and disengaging from the male buckle). At this time, both are in the released state, and the controller body 30 can move away from the fixed base 10 in a preset direction under the external force, eventually extending out of the seat surface for easy operation by the user. When the controller body 30 is finished using, the user can apply a force in a preset direction to the controller body 30 again, causing the controller body 30 to move closer to the fixed direction until the first locking member 20 and the second locking member 40 are locked again (locked state), completing the storage.
[0060] Based on the above, this solution utilizes the movable cooperation and locking structure between the fixed base 10 and the hand controller body 30 to allow the hand controller body 30 to be completely housed within the fixed base 10 (e.g., hidden within the seat cushion), thus avoiding the risk of collision damage caused by long-term exposure of the hand controller body 30. Furthermore, operating the hand controller body 30 only requires applying a force in a preset direction to slide it into the fixed base 10 and lock it, or to release and extend it. This is particularly suitable for users with mobility impairments and other users who require high ease of operation, significantly improving the user experience.
[0061] In addition, in this solution, the hand controller body 30 can be completely hidden in the fixed base 10. In actual application scenarios, the hand controller body 30 is flush with the surface of the seat cushion or only the edge is exposed, maintaining the coordination of the seat appearance, avoiding the hand controller body 30 occupying extra space of the seat, reducing the seat packaging volume, and reducing warehousing and transportation costs.
[0062] Please continue to refer to the instruction manual appendix. Figures 3-8 Based on the above basic structure, an elastic element 50 is added between the fixed base 10 and the hand controller body 30. The two ends of the elastic element 50 act on the fixed base 10 and the hand controller body 30 respectively, providing the hand controller body 30 with a tendency to extend out of the fixed base 10.
[0063] For example, when the fixed base 10 is a hollow shell, the hand controller body 30 can be housed in the shell by sliding rails, and the elastic element 50 is arranged between the bottom of the shell and the back of the hand controller body 30 along the sliding rail direction.
[0064] In this embodiment, the specific form of the elastic element 50 can be selected according to actual needs. For example, a spring can be used, which acts on the fixed base 10 and the hand controller body 30 at its two ends respectively. It stores elastic potential energy through compression or stretching deformation, so that the hand controller body 30 has a tendency to extend out of the fixed base 10. Alternatively, an elastic rubber block can be used. A highly elastic rubber material can be selected, cut into columnar or block shapes, and the two ends can be glued or snapped onto the surfaces opposite to the fixed base 10 and the hand controller body 30 respectively. It provides thrust through its own compression and rebound. Alternatively, a spring sheet can be used. It can be made of metal material (such as spring steel) into an arc or "S" shaped spring sheet, which provides elastic force through the rebound tendency of bending deformation.
[0065] The two ends of the elastic element 50 act directly or indirectly on the fixed base 10 and the hand controller body 30, respectively. When the hand controller body 30 moves towards the fixed base 10 (retracting process), the elastic element 50 is compressed (or stretched, or bent, etc.), generating an outward elastic force; when the hand controller body 30 is not locked by the first locking member 20 and the second locking member 40, this elastic force will push the hand controller body 30 away from the fixed base 10 (extending process), without the need for the user to manually pull it.
[0066] In this embodiment, the elastic element 50 can automatically pop out the hand controller body 30 through its own elastic force. When the first locking member 20 and the second locking member 40 switch from the locked state to the released state, the hand controller body 30 can automatically extend out of the fixed base 10 (such as the surface of the seat) under the action of elastic force without the user having to apply additional force. This is especially suitable for people with mobility impairments and other groups, and significantly reduces the difficulty of operation.
[0067] Meanwhile, the uniform elastic force provided by the elastic element 50 can also prevent the hand controller body 30 from being stuck or rubbing during the extension process, resulting in unsmooth movement. Compared with the method of relying on the user to pull when there is no elastic element 50, the movement is more reliable and reduces operation failures.
[0068] Furthermore, when the hand controller body 30 is stored in the fixed base 10, the elastic force provided by the elastic element 50 allows the second locking member 40 to interact with the first locking member 20 to ensure the stability of the locked state, avoiding accidental unlocking or popping out due to seat shaking, thus solving the problem of easy loosening of the existing simple snap-fit structure.
[0069] The fixed base 10 is provided with a support cylinder 11, and a limiting hole 111 is provided in the support cylinder 11 to pass through the inside and outside of the fixed base 10;
[0070] The hand controller body 30 is provided with a support rod 31, which is movably connected to the limiting hole 111;
[0071] The elastic element 50 is a compression spring, which is sleeved on the support rod 31, and the end of the compression spring near the fixed base 10 is set in the limiting hole 111.
[0072] Based on the above implementation methods, such as Figures 3-8 As shown, this embodiment further refines the cooperation structure of the fixed base 10, the hand controller body 30, and the elastic element 50. The fixed base 10 is provided with a support cylinder 11, which is a protruding structure on the fixed base 10. It can be integrally formed with the fixed base 10 (such as by plastic injection molding) or fixed to the fixed base 10 by screws or other means. Its shape can be designed as cylindrical, square, or polygonal according to requirements. For example, a cylindrical structure can be used, and its length protruding from the fixed base 10 is slightly shorter than the depth of the storage space provided by the fixed base 10 for the hand controller body 30, ensuring that the storage space of the hand controller body 30 is not affected.
[0073] The support cylinder 11 has a limiting hole 111 that connects the inside and outside of the fixed base 10. Specifically, the limiting hole 111 extends from the end of the support cylinder 11 closest to the hand controller body 30 to the end of the support cylinder 11 furthest from the hand controller body 30, forming a channel for the support rod 31 to pass through. The cross-sectional shape of the limiting hole 111 matches that of the support rod 31 (e.g., circular or square). The hand controller body 30 is equipped with the support rod 31. The diameter of the limiting hole 111 is slightly larger than the diameter of the support rod 31, ensuring that the support rod 31 can be movably inserted into the limiting hole 111 while also limiting the lateral displacement of the support rod 31 (hand controller body 30).
[0074] The support rod 31 is specifically located on the side of the hand controller body 30 facing the fixed base 10. The support rod 31 can be integrally formed with the hand controller body 30 (such as a protruding post on the back of the hand controller housing), or fixed by welding, screwing, or other methods. The length of the support rod 31 must be such that when the hand controller body 30 is housed in the fixed base 10, the end of the support rod 31 away from the hand controller body 30 can be inserted into the limiting hole 111; when the hand controller body 30 extends out of the fixed base 10, a portion of the support rod 31 still remains in the limiting hole 111 (to prevent it from detaching).
[0075] In this embodiment, the elastic element 50 is a compression spring with an inner diameter slightly larger than the diameter of the support rod 31 and smaller than the diameter of the limiting hole 111. A limiting platform 112 is provided at the end of the limiting hole 111 furthest from the controller body 30. The compression spring is sleeved on the support rod 31 to prevent it from falling off during use. One end of the compression spring is located within the limiting hole 111 and acts on the fixed base 10 through the limiting platform 112. When the controller body 30 is housed in the fixed base 10, the compression spring is further compressed, storing more elastic potential energy. When the first locking member 20 and the second locking member 40 are unlocked (released state), the compression spring releases its elastic potential energy to a state of natural extension or slight compression, causing the support rod 31 to slide along the limiting hole 111 outwards from the fixed base 10, thus extending the controller body 30.
[0076] In this embodiment, the retraction and ejection of the hand controller body 30 are smoother, effectively reducing operational malfunctions and improving user experience. The compression spring, sleeved on the support rod 31 and with its rear end confined within the limiting hole 111 of the support cylinder 11, prevents the spring from dislodging during repeated compression and rebound, reducing component wear. Furthermore, the support cylinder 11, support rod 31, and compression spring are compactly integrated between the fixed base 10 and the hand controller body 30, avoiding additional space occupation on the seat's exterior, maintaining the overall aesthetics of the seat, and preserving the advantage of saving packaging volume.
[0077] Based on the above-mentioned hand controller storage mechanism, which also includes elastic elements 50, the hand controller storage mechanism is provided with multiple elastic elements 50 and multiple first locking elements 20, and the number of second locking elements 40 corresponds to the number of first locking elements 20.
[0078] It is understood that the specific number of elastic elements 50 and the first locking member 20 (and the second locking member 40) can be designed as 2, 3, etc. (e.g., 2) according to the width of the hand controller body 30. Multiple elastic elements 50 are arranged at intervals along the width direction of the hand controller body 30 (i.e., perpendicular to the hand controller's storage / extension direction) on the side of the fixed base 10 (such as the base housing 15) facing the hand controller body 30, for example, evenly distributed laterally inside the fixed base 10. One end of each elastic element 50 is fixed to the fixed base 10, and the other end is used to abut against the back of the hand controller body 30. The number of first locking elements 20 can be the same as that of elastic elements 50 (e.g., 2 elastic elements 50 correspond to 2 first locking elements 20), or it can be more or less than the number of elastic elements 50. The first locking elements 20 are also arranged at intervals along the width direction of the hand controller body 30 on the fixed base 10, and a first locking element 20 is provided between any two adjacent elastic elements 50. For example, when there are 2 elastic elements 50, multiple first locking elements 20 are located between the 2 elastic elements 50. When there are 3 or more elastic elements 50, the elastic elements 50 and the first locking elements 20 can be arranged alternately in the width direction of the hand controller body 30.
[0079] Multiple second locking elements 40, corresponding in number to the first locking element 20, are disposed on the side of the hand controller body 30 (such as the hand controller housing) facing the fixed base 10, and are also arranged along the width direction of the hand controller body 30. The position of each second locking element 40 corresponds one-to-one with the first locking element 20 on the fixed base 10 (such as one first locking element 20 corresponding to one second locking element 40, and another first locking element 20 corresponding to another second locking element 40), ensuring that each locking element can be precisely engaged when the hand controller body 30 is stored.
[0080] During the storage process of the hand controller body 30, when the hand controller body 30 moves toward the fixed base 10, multiple elastic elements 50 are simultaneously compressed (such as two springs deforming synchronously), storing elastic potential energy; at the same time, multiple second locking members 40 on the hand controller body 30 move with the body and gradually approach the corresponding first locking members 20 on the fixed base 10. Finally, all the first locking members 20 and second locking members 40 enter the locking state synchronously, jointly restricting the extension of the hand controller body 30; during the extension process of the hand controller body 30, multiple first locking members 20 and second locking members 40 unlock to the release state synchronously, and multiple elastic elements 50 release elastic potential energy synchronously, jointly applying an outward pushing force to the hand controller body 30, pushing the hand controller body 30 to smoothly extend out of the fixed base 10 in a preset direction.
[0081] In this embodiment, multiple elastic elements 50 are arranged at intervals along the width of the controller body 30, providing elastic force synchronously to ensure that the controller body 30 is subjected to balanced force during extension and moves smoothly along a preset trajectory, avoiding tilting or jamming. Simultaneously, multiple first locking elements 20 and second locking elements 40 lock / unlock synchronously. Through multiple sets of cooperation to distribute the force, even if individual locking elements experience slight wear, the remaining locking elements can still ensure the stable storage of the controller body 30, significantly reducing the risk of accidental unlocking or ejection and improving structural reliability.
[0082] In one embodiment, such as Figures 3-7 As shown, based on any of the above embodiments, the fixed base 10 is provided with a plurality of first guide structures 12, and correspondingly, the hand controller body 30 is provided with a plurality of second guide structures 32.
[0083] The number of first guide structures 12 can be designed to be 2, 3, or other configurations depending on the width of the hand controller body 30. Multiple first guide structures 12 are arranged at intervals along the width direction of the hand controller body 30 (i.e., laterally perpendicular to the retraction / extension direction). For example, if the first guide structure 12 is a slide rail, multiple parallel strip-shaped tracks can be protruded from the inner wall of the fixed base 10, with a "T" or "U" shaped cross-section, extending along the hand controller's retraction / extension direction. If the first guide structure 12 is a groove, two parallel grooves can be opened on the inner wall of the fixed base 10, with the groove cross-section matching the second guide structure 32 (e.g., rectangular or dovetail-shaped), also extending along the retraction / extension direction.
[0084] The number of second guide structures 32 is the same as that of the first guide structures 12, and they are arranged along the width direction of the hand controller body 30, with their positions corresponding one-to-one with the first guide structures 12 (e.g., the first guide structure 12 on the left corresponds to the second guide structure 32 on the left side of the hand controller body 30, and the same applies to the right side). For example, if the first guide structure 12 is a "T"-shaped slide rail, the second guide structure 32 can be a "T"-shaped slider, which can be embedded in the slide rail and slide along it; if the first guide structure 12 is a dovetail-shaped groove, the second guide structure 32 can be a dovetail-shaped protrusion, which can be inserted into the groove and move along it.
[0085] When the hand controller body 30 is retracted (moving towards the fixed base 10) or extended (moving away from the fixed base 10), the second guide structure 32 always moves within the first guide structure 12 along a preset trajectory (such as a horizontal straight line), restricting the degree of freedom of the hand controller body 30 from multiple points, making the retraction and extension of the hand controller body 30 smoother and avoiding jamming or tilting. By stabilizing the movement trajectory, the guide structure ensures that the hand controller body 30 can be accurately retracted into the fixed base 10 (such as being completely embedded in the seat cushion) or accurately extended to a preset position (such as a fixed area on the surface of the seat cushion), avoiding incomplete retraction (partial exposure) or tilted extension (damaging the appearance) caused by misalignment, further enhancing the harmony of the seat's appearance.
[0086] Furthermore, multiple guide structures (first guide structure 12 and second guide structure 32) disperse the frictional force during the movement of the hand controller body 30, preventing rapid wear caused by concentrated force on a single guide structure. Simultaneously, the stable motion trajectory reduces collisions or friction between components, extending the overall service life of the mechanism and indirectly improving product reliability.
[0087] Further, please continue to refer to the appendix to the instruction manual. Figures 3-7 There are two of each of the first guide structure 12 and the second guide structure 32. The first guide structure 12 is a guide rail, which includes a first limiting plate 121 and a guide plate 122. Both first limiting plates 121 are mounted on the fixed base 10 and extend vertically. The guide plate 122 is connected to the first limiting plate 121 and is set at an angle. The two guide plates 122 extend in directions away from each other, and a guide groove 123 is formed between the guide plate 122 and the fixed base 10. Correspondingly, the second guide structure 32 is a slider, which is slidably mounted within the guide groove 123. Furthermore, a second limiting plate 321, opposite to the edge of the guide plate 122, is also mounted outside the guide groove 123 on the slider.
[0088] It is understood that the first limiting plate 121 (and the guide plate 122) can be integrally formed with the fixed base 10 (e.g., formed simultaneously during plastic injection molding). The guide plate 122 forms an angle with the first limiting plate 121 (e.g., 60° to <180°), and the two guide plates 122 extend in mutually distancing directions. For example, the guide plate 122 of the left guide rail extends horizontally to the left, and the guide plate 122 of the right guide rail extends horizontally to the right.
[0089] The number of sliders is the same as that of the guide rails, and their shape is adapted to the guide groove 123 (such as rectangular or trapezoidal). For example, the sliders can be designed as strip structures protruding from the back of the hand controller body 30, with a thickness slightly smaller than that of the guide groove 123, to ensure smooth sliding of the sliders within the guide groove 123.
[0090] When the slider is embedded in the guide groove 123, its upper and lower surfaces correspond to the lower surface of the guide plate 122 and the side wall of the fixed base 10, respectively. Its inner side (such as the right side of the left slider and the left side of the right slider) corresponds to the outer side of the first limiting plate 121 (such as the right side of the first limiting plate 121 of the left slide rail and the left side of the first limiting plate 121 of the right slide rail), forming an in-groove limiting structure. When the hand controller body 30 is retracted (moving towards the fixed base 10) or extended (moving away from the fixed base 10), the slider slides along the length of the guide groove 123. The guide plate 122 and the inner wall of the fixed base 10 restrict the slider's vertical and horizontal (width direction) offset, ensuring that the hand controller body 30 moves horizontally, preventing the hand controller from jumping up and down and tilting laterally, and ensuring that the movement trajectory of the hand controller body 30 is accurate.
[0091] The second limiting plate 321 located outside the slider (second guide structure 32) can cooperate with the guide plate 122 to further limit the movement, thereby further ensuring the movement accuracy of the hand controller body 30.
[0092] The precise cooperation between the guide rail and the slider ensures that the hand controller body 30 can be completely stored inside the fixed base 10 (such as deep in the seat cushion storage groove 61), and is flush with the surface of the seat cushion after being stored. Because there is no deviation during movement, there will be no situation of "one side protruding and one side sinking", thus maintaining the integrity of the seat's appearance.
[0093] Please refer to the instruction manual attached. Figures 3-10 Based on any of the above embodiments, the fixed base 10 is provided with a hollow receiving cavity 13, the shape of which is adapted to the hand controller body 30, and the size is slightly larger than the hand controller body 30 to ensure that the hand controller body 30 can move smoothly inside. An opening 14 communicating with the receiving cavity 13 is provided on one side of the fixed base 10. The shape of the opening 14 matches the cross-section of the hand controller body 30, and the size is such that the hand controller body 30 can just pass through, ensuring both sufficient space for movement and preventing excessive shaking of the hand controller body 30 during movement. A first locking member 20 is disposed within the receiving cavity 13. The hand controller body 30 is movably disposed in the receiving cavity 13 through the opening 14, and a second locking member 40 is disposed on the side of the hand controller body 30 located within the receiving cavity 13. For example, if the hand controller body 30 is flat and elongated, the receiving cavity 13 can be a corresponding elongated chamber, and the opening 14 is an elongated notch, which is opened on the side of the fixed base 10 facing the surface of the seat cushion 60 (such as the left or right side of the seat cushion surface).
[0094] It should be understood that the specific positions of the first locking member 20 and the second locking member 40 can be determined according to the storage position of the hand controller body 30. If the back of the hand controller body 30 is in contact with the bottom of the receiving cavity 13 when it is fully stored, the first locking member 20 can be fixed at the bottom of the receiving cavity 13, and the second locking member 40 can be fixed on the back of the hand controller body 30 accordingly. If the side is in contact with the inner wall of the receiving cavity 13 when stored, the first locking member 20 can be set on the inner side wall of the receiving cavity 13, and the second locking member 40 can be set on the outer side of the hand controller body 30 to ensure precise matching with the second locking member 40 of the hand controller body 30.
[0095] When the controller body 30 is stored in the fixed base 10, the side of the controller body 30 located in the accommodating cavity 13 (such as the back) is in contact with the inner wall of the accommodating cavity 13. At this time, the second locking member 40 contacts the first locking member 20 in the accommodating cavity 13 and enters the locking state, preventing the controller body 30 from popping out of the opening 14, thus achieving stable storage. When the controller body 30 extends out of the fixed base 10, the first locking member 20 and the second locking member 40 are unlocked (released state). The controller body 30 can move out of the accommodating cavity 13 through the opening 14 under the pushing force of the elastic element 50 or the pull of the user, and finally extend out of the fixed base 10 from the opening 14, which is convenient for the user to operate.
[0096] In this embodiment, the accommodating cavity 13 provides an independent space for the hand controller body 30. Its cavity wall can completely isolate the hand controller body 30 from other parts of the seat. Even if the seat cushion is deformed by pressure, the rigid cavity wall of the accommodating cavity 13 can prevent external parts (such as sponge or fabric) from contacting the hand controller body 30, avoiding scratches, squeezing, or jamming caused by interference. The presence of the accommodating cavity 13 can also protect the surface integrity of the hand controller body 30 (such as preventing the buttons from being caught by the fabric) and the stability of the internal structure (such as preventing the circuit from being squeezed and damaged), extending its service life and ensuring long-term reliable operation.
[0097] In a further embodiment, based on the above-mentioned scheme of providing a hollow receiving cavity 13 within the fixed base 10, such as... Figures 3-10As shown, the fixed base 10 includes a base shell 15 and an outer buckle 16. The base shell 15 is a shell structure with a certain strength (such as a plastic injection-molded box), with a hollow interior forming a receiving cavity 13 (for housing the hand controller body 30), and an opening 14 on one side communicating with the receiving cavity 13. When the base shell 15 is installed inside the seat cushion 60, the size of the base shell 15 matches the installation space inside the seat cushion 60 (such as the storage slot 61 reserved in the seat cushion 60), and it can be fixed inside the seat cushion 60 (frame 70) with screws. The receiving cavity 13 faces outwards from the seat cushion 60 through the opening 14 (i.e., the opening 14 is exposed on the surface of the seat cushion 60, facilitating the extension of the hand controller body 30). The outer buckle 16 is a frame-shaped or ring-shaped structure (such as a plastic plate) surrounding the opening 14, and is detachably connected to the base shell 15 (e.g., by means of a snap-fit or slot engagement). When the base housing 15 is installed inside the seat cushion 60, a portion (inner side) of the outer buckle 16 is embedded between the fabric and filling of the seat cushion 60 to form an assembly relationship with the base housing 15, while the other portion (outer side) protrudes from the surface of the seat cushion 60 and abuts against it (such as by fitting).
[0098] In this embodiment, the base housing 15 can be fixed inside the seat cushion 60 with screws. The outer buckle 16 is designed with part inside the seat cushion 60 and part abutting against the surface of the seat cushion 60, so that it can form an inner and outer clamping structure with the base housing 15 on the seat cushion 60. For example, the base housing 15 is embedded in the filling of the seat cushion 60 and fixed to the frame 70 inside the seat cushion 60, and the outer buckle 16 abuts against the surface fabric of the seat cushion 60. The base housing 15 is doubly fixed to prevent the hand controller storage mechanism from shaking inside the seat cushion 60 and ensure the stability of the hand controller body 30 when it is stored / extended.
[0099] Secondly, through the above-mentioned arrangement, the base shell 15 is hidden inside the seat cushion 60 and communicates with the outside only through the opening 14. The outer buckle 16 surrounds the opening 14 and fits the surface of the seat cushion 60, which can cover the gap between the base shell 15 and the seat cushion 60 (such as the junction of the plastic shell and the fabric), so that the edge of the opening 14 and the surface of the seat cushion 60 transition smoothly, avoiding the abruptness of the exposed base shell 15 and maintaining the harmony of the seat appearance.
[0100] In addition, the way the outer buckle 16 surrounds the opening 14 can form a physical barrier between the opening 14 and the seat 60, which can prevent the fabric of the seat 60 (such as wrinkled fabric) from being rolled into the receiving cavity 13 during the operation of the hand controller, and at the same time prevent foreign objects such as dust and liquid from entering the receiving cavity 13 or the interior of the seat 60 through the gaps, thus extending the service life of the hand controller storage mechanism.
[0101] Based on any of the above embodiments, one of the first locking member 20 and the second locking member 40 is a male locking buckle and the other is a female locking buckle (the two can be interchanged, that is, when the first locking member 20 is a male locking buckle, the second locking member 40 is a female locking buckle, and vice versa).
[0102] The locking female buckle is provided with multiple jaws 21, which can move relative to the locking female buckle to retract and expand with each other in the locked and released states. A first abutment 22 is provided between the multiple jaws 21 for the locking male buckle to abut against. The multiple jaws 21 can retract or expand with each other when the first abutment 22 is subjected to a force in a first direction. Correspondingly, the locking male buckle is provided with a claw 41 corresponding to each jaw 21, and a second abutment 42 is provided between the multiple claw 41 for abutting against the first abutment 22.
[0103] As one specific implementation scheme, the locking female buckle can be a rebound device, whose grippers 21 are controlled to close and open by an internal spring.
[0104] Specifically, when the hand controller body 30 moves (retracts) towards the fixed base 10, the locking male buckle gradually inserts into the locking female buckle. The second abutment 42 of the locking male buckle first contacts the first abutment 22 of the locking female buckle and applies a force in the first direction (such as pressure inward along the male buckle axis). At this time, multiple claws 21 are forced to close due to the pressure of the inner wall of the male buckle, and finally clamp the claw 41 of the male buckle, forming a locked state and restricting the extension of the hand controller body 30. When the user presses the hand controller body 30 again, the hand controller drives the locking male buckle (or female buckle) to apply a force in the first direction to the other party. The second abutment 42 continues to press against the first abutment 22, triggering the elastic reset mechanism of the claws 21 (such as the internal spring of the rebounder). Multiple claws 21 elastically unfold from the closed state and disengage from the claw 41 of the male buckle. At this time, the locking male buckle and the locking female buckle enter the released state, and the hand controller body 30 can be ejected under the push of the elastic element 50.
[0105] In this embodiment, the locking male buckle and locking female buckle can be switched simply by "pressing". One press locks the buckle in place, and another press releases it. No extra steps are required, making it especially suitable for people with mobility impairments. It is easy to operate and provides a comfortable experience.
[0106] The locking claw 21 of the female buckle and the locking claw 41 of the male buckle are multiple sets of cooperation, and multi-point locking is achieved by uniform force in the circumference, which ensures the locking strength of the first locking member 20 and the second locking member 40, and significantly reduces the risk of the hand controller body 30 accidentally popping out in the storage state.
[0107] Please refer to the instruction manual attached. Figures 1-6This embodiment also provides a seat, which includes a seat cushion 60 and a hand controller storage mechanism as provided in any of the above embodiments. The seat cushion 60 is the seating part of the seat, typically filled with elastic materials such as sponge, and covered with fabric (such as textiles or leather). A storage groove 61 is provided on one side of the seat cushion 60 (such as the side or front edge near the user's hand). The storage groove 61 is an inwardly recessed cavity structure, its shape adapted to the fixing base 10 of the hand controller storage mechanism (such as a cuboid groove) to accommodate the fixing base 10 and provide space for the movement of the hand controller body 30. The opening of the storage groove 61 faces the outer side or surface of the seat cushion 60, and the shape of the opening matches the cross-section of the hand controller body 30 (such as a strip), ensuring that the hand controller body 30 can smoothly enter and exit.
[0108] Understandably, the storage slot 61 serves as the mounting carrier for the hand controller storage mechanism. The fixing base 10 is embedded in the storage slot 61 and fixed to the seat cushion 60, making the hand controller storage mechanism part of the seat cushion 60. The hand controller body 30 can reciprocate between the inside of the storage slot 61 (and the receiving cavity 13) and the outside of the seat cushion 60 through the slot of the storage slot 61 and the opening 14 of the fixing base 10.
[0109] In summary, by setting a storage slot 61 on the seat cushion 60 and integrating a hand controller storage mechanism, this seat fundamentally solves the defects of existing exposed hand controllers, achieving a comprehensive effect of convenient storage, harmonious appearance, comfortable operation, and optimized cost.
[0110] Finally, it should be noted that the above embodiments are only optional embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
