[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0037] In the related art, a safety seat can usually be provided with an armrest on the side of a booster cushion to prevent a child from tipping over from the side of the safety seat during riding. However, the armrests on the booster cushions in the related art are mostly fixedly provided on the side of the booster cushions, and the space occupied by the armrests needs to be considered during the storage or packing process of the booster cushions, resulting in a large space occupied by the booster cushions during storage or packing, which is inconvenient for the transportation and storage of the safety seat, and reduces the practicality of the safety seat. In view of the above problems, the utility model proposes a booster cushion 100.

[0038] See also Figures 1 to 12In one embodiment of the utility model, the height-enhancing cushion 100 includes a seat cushion 10, a support seat 30, an armrest 50 and a limiting structure 70. A storage space 151 is formed on the side of the seat cushion 10; the support seat 30 is movably disposed in the storage space 151, and the support seat 30 has a first state of extending out of the storage space 151 and a second state of at least partially being accommodated in the storage space 151; the armrest 50 is movably connected to the support seat 30, and the armrest 50 has a storage state and an extended state; the limiting structure 70 is installed on the seat cushion 10 and is disposed between the seat cushion 10 and the support seat 30. The limiting structure 70 limits and fixes the support seat 30 when the support seat 30 is in the first state and / or the second state.

[0039] It is understandable that the safety seat can be placed directly on the seat of the vehicle, or a strap or buckle structure that matches the seat can be set on the height-enhancing cushion 100 or the backrest of the safety seat, so that the safety seat can be stably installed on the seat of the vehicle to ensure the safety of the passenger. On the safety seat, the support seat 30 and the armrest 50 on the height-enhancing cushion 100 can not only support the passenger's arms, but also better wrap the passenger to prevent the passenger from falling from the side of the safety seat, thereby improving the riding comfort and safety of the safety seat.

[0040] In the present application, a hollow notch or a groove can be provided on the side of the seat cushion 10 to form a storage space 151, and the support seat 30 can be set in the storage space 151, and the support seat 30 can be movably set relative to the seat cushion in the storage space 151. For example, the support seat 30 can be conveniently disassembled and assembled on the seat cushion 10 by means of bolts or snaps, and the support seat 30 can be disassembled and stored in the storage space 151; or the seat cushion 10 and the support seat 30 can be connected by a rotating structure such as a rotating shaft or a hinge, so that the support seat 30 can be rotatably set in the storage space 151; or the support seat 30 can be guided to be lifted and lowered in the storage space 151. Among them, taking the partial manner in which the support seat 30 can be lifted and moved in the storage space 151 as an example, a lifting guide rail or a lifting arm can be set in the storage space 151 to connect the support seat 30, so that the support seat 30 can be lifted and moved in the storage space 151; or the size of the storage space 151 can be set to correspond to the outer peripheral size of the support seat 30, so that the support seat 30 can be lifted and moved in the storage space 151 under the guiding limit of the storage space 151 by manually lifting the support seat 30. Furthermore, the support base 30 can be raised when the height-enhancing cushion 100 is needed for use by the passenger, so that the support base 30 can be in a first state of extending out from the storage space 151 at this time, thereby ensuring that the support base 30 supports the passenger's arms and protects the passenger when riding; and the support base 30 can be lowered when the height-enhancing cushion 100 needs to be stored or boxed, so that the support base 30 can be in a second state of being at least partially accommodated in the storage space 151 at this time, so that the support base 30 can be better accommodated in the seat cushion 10 to reduce the overall volume of the height-enhancing cushion 100 when stored, which is conducive to better reducing the packaging cost of the raised structure when the height-enhancing cushion 100 is boxed, reducing the space occupied by the height-enhancing cushion 100 when stored, and realizing a more convenient and practical structural design of the safety seat body 31.

[0041] Since the support seat 30 needs to be movably stored on the seat cushion 10, in order to ensure the seating area of ​​the seat cushion 10, the end surface of the support seat 30 cannot well support the entire arm of the passenger. At this time, an armrest 50 can be provided on the support seat 30. By movably connecting the armrest 50 to the support seat 30, the armrest 50 can be slidably set on the support seat 30 or rotatably set on the support seat 30, so that the armrest 50 can have a stored state and an extended state following the first state and the second state of the support seat 30. That is, when the support seat 30 is in the first state for use by the passenger, the armrest 50 can be moved on the support seat 30 to protrude on one side of the support seat 30 according to the passenger's use needs, so that the armrest 50 can be in an extended state at this time, which is conducive to better increasing the supporting area of ​​the height-enhancing cushion 100 for the passenger's arm, and at the same time can better improve the height-enhancing cushion 100 The protection against horizontal movement of passengers can better improve the riding comfort and safety of the height-enhancing cushion 100. When the support seat 30 needs to be adjusted to the second state to realize the storage or packing of the height-enhancing cushion 100, since the armrest 50 extends out and protrudes from one side of the support seat 30, there is a certain probability that the armrest 50 will collide and interfere with the seat cushion 10 during the process of the support seat 30 being moved and stored into the storage space 151. Therefore, before the support seat 30 needs to be adjusted to the second state, the armrest 50 can be moved on the support seat 30 until it at least partially overlaps with the support seat 30, so that the armrest 50 can be in the storage state stored on the support seat 30 at this time, thereby effectively avoiding the armrest 50 from interfering with the seat cushion 10 during the process of the support seat 30 being stored into the storage space 151, thereby ensuring the reduction of the overall occupied space of the height-enhancing cushion 100 and further improving the practicality and structural reliability of the height-enhancing cushion 100. Among them, the structure that drives the armrest 50 to move on the support base 30 and the structure that drives the support base 30 to move up and down can also be linked through a linkage mechanism such as a connecting rod or a gear, so that when the support base 30 is adjusted to the first state on the seat cushion 10, the armrest 50 can be simultaneously driven to adjust to the extended state on the support base 30, and when the support base 30 is adjusted to the second state on the seat cushion 10, the armrest 50 can be simultaneously driven to adjust to the storage state on the support base 30, which is conducive to better reducing the operating procedures when using the height-increasing cushion 100 and further improving the operational convenience of the height-increasing cushion 100.

[0042] The support seat 30 is movably arranged on the height-enhancing cushion 100, so that the support seat 30 is in the first state for the passenger to sit on or in the second state for storing the height-enhancing cushion 100, and the limiting structure 70 can be used to connect the seat cushion 10 and the support seat 30 between the seat cushion 10 and the support seat 30, so that the support seat 30 can be supported and fixed by the limiting structure 70 in the first state or the second state, thereby ensuring that the support seat 30 can more stably support the passenger's arm in the first state, and avoid the support seat 30 being retracted into the storage space 151 due to external force; and it can also ensure that the support seat 30 can be stably accommodated in the storage space 151 in the second state, preventing the height-enhancing cushion 100 from being turned over or tipped over with a certain probability that the support seat 30 will extend out of the storage space 151 under the action of gravity, thereby better ensuring the overall structural stability of the height-enhancing cushion 100 during use or storage. The limiting structure 70 can be a buckle structure with a certain elasticity installed on the side wall of the seat cushion 10 and cooperated with the support seat 30, so that the support seat 30 can use the elastic retraction of the limiting structure 70 to avoid the movement of the support seat 30 during the process of adjusting the support seat 30 to the first state or the second state, and can be correspondingly clamped and fixed with the limiting structure 70 when the support seat 30 moves to the position of the first state or the second state, so as to ensure the limiting and fixing effect of the limiting structure 70 on the support seat 30. Alternatively, the limiting structure 70 can be telescopically arranged on the side wall of the seat cushion 10 in an electrically controlled manner, so that the limiting structure 70 can automatically retract to avoid the lifting and moving of the support seat 30, and can automatically extend to abut the support seat 30 or clamp the support seat 30 when the support seat 30 moves into place to achieve the limiting and fixing of the support seat 30. In addition, under the cooperation of the limiting structure 70, the overall structural stability of the height-increasing cushion 100 during use and storage can be better guaranteed, so that passengers can have a better use experience, and the practicality and structural reliability of the height-increasing cushion 100 are further improved.

[0043] The technical solution of the present invention enables the support seat 30 to be movably arranged in the storage space 151 on the side of the seat cushion 10, so that the height-enhancing cushion 100 can be raised on the seat cushion 10 to be in a first state of extending out of the storage space 151 when in use, and can be lowered to be in a second state of being accommodated in the storage space 151 during factory packaging and daily storage, so that the height-enhancing cushion 100 can store the support seat 30 supporting the armrest 50 into the seat cushion 10, effectively reducing the overall volume of the height-enhancing cushion 100 when stored or packaged, reducing the space occupied by the height-enhancing cushion 100, and further reducing the packaging cost of the height-enhancing cushion 100. Among them, by setting a limiting structure 70 between the seat cushion 10 and the support seat 30, the limiting structure 70 can be used to clamp on the support seat 30 when the support seat 30 is in the first state or the second state to achieve the limiting fixation of the support seat 30, which is conducive to better improving the structural stability of the support seat 30 in the first state and the second state, and better ensuring the stable use and storage of the height-enhancing cushion 100. By movably setting the armrest 50 on the support seat 30, the armrest 50 can be moved to a side of the support seat 30 in an extended state to increase the support area of ​​the height-enhancing cushion 100 for the user's arm, and at the same time, the armrest 50 can be moved to a storage state where it at least partially overlaps with the support seat 30, better avoiding the interference between the armrest 50 and the seat cushion 10 when the support seat 30 is in the second state, ensuring that the volume of the height-enhancing cushion 100 is reduced when it is stored or packed, which is conducive to better improving the storage and packing convenience and structural stability of the height-enhancing cushion 100, and improving the practicality and reliability of the safety seat.

[0044] See also Figures 6 to 9 In an embodiment of the utility model, the support seat 30 includes a seat body 31 and a connecting structure 33, and at least part of the structure of the seat body 31 is arranged in the storage space 151; the connecting structure 33 is arranged in the storage space 151, and connects the seat cushion 10 and the seat body 31 so that the seat body 31 can switch between the first state and the second state.

[0045] In this embodiment, the support seat 30 can use the connection structure 33 to connect the seat cushion 10 and the seat body 31 in the storage space 151, so that the seat body 31 can move in the storage space 151 under the active driving action of the connection structure 33, or the connection structure 33 can be used to guide the seat body 31 and reduce the friction when the seat body 31 moves, so as to ensure the stable and reliable movement of the seat body 31 in the storage space 151. The seat body 31 can be a block structure for the support seat 30 to support the passenger's arms. In this case, the armrest 50 can be connected to the seat body 31 to ensure that the height-enhancing cushion 100 supports and protects the passenger when riding; and the connection structure 33 can be an electric-controlled lifting device or an electric-controlled telescopic device set at the bottom or side of the seat body 31, or can be a guide rail slider structure connecting the seat body 31 and the seat cushion 10, or can be a motor or a steering pump group connecting the seat body 31 and the seat cushion 10. The seat body 31 can be driven to move up and down or rotate by the electrically controlled connection structure 33 to realize automatic control of the height-enhancing cushion 100, or the seat body 31 can be guided and driven to move by the connection structure 33 when the passenger manually pulls the seat body 31, thereby reducing the friction resistance between the seat body 31 and the seat cushion 10 during movement, thereby better improving the operational convenience of the height-enhancing cushion 100 and further improving the practicality and reliability of the safety seat.

[0046] See also Figure 6 and Figure 7 In an embodiment of the present utility model, the connection structure 33 is an elastic support member 33a, the elastic support member 33a connects the seat cushion 10 and the seat body 31, and the seat body 31 compresses the elastic support member 33a when the support seat 30 is in the second state.

[0047] In this embodiment, the connecting structure 33 can be an elastic support member 33a of a spring or elastic silicone, elastic rubber, etc., which is connected to the bottom of the seat body 31 and the seat cushion 10 by the elastic support member. When the support seat 30 is adjusted to the second state to realize the storage of the height-enhancing cushion 100, an external force acts on the seat body 31 to compress the elastic support member 33a and retract it into the storage space 151. When the seat body 31 is stably moved to the position where the support seat 30 is in the second state, the limiting structure 70 can be controlled to correspond to the connection between the seat body 31 and the seat cushion 10 at this time, so as to realize the limiting fixation of the seat body 31, so that the support seat 30 can maintain the elastic deformation of the elastic support member 33a and stably maintain the seat body 31 contained in the storage space 151; and then, when it is necessary to make the support seat 30 in the first state where the seat body 31 extends out of the storage space 151 in the future, the limiting structure 70 can be directly controlled to loosen the connection and fixation of the support seat 30. At this time, the seat body 31 can be stably driven to rise and move out of the storage space 151 under the action of the elastic support member 33a restoring the elastic deformation, and the limiting structure 70 can be controlled to limit and fix the seat body 31 again when the support seat 30 is stably in the first state, so as to prevent the seat body 31 from being retracted into the storage space 151 due to the large force of the passenger's arm when the passenger is sitting, thereby ensuring that the height-enhancing cushion 100 stably and reliably supports the passenger's arm, and further improving the structural stability and reliability of the height-enhancing cushion 100.

[0048] By utilizing the elastic support member 33a to drive the seat body 31 to rise and fall to adjust the support seat 30 between the first state or the second state, the overall structure of the height-increasing pad 100 can be made simpler, and the elastic force energy storage of the elastic support member 33a can realize a more convenient lifting and lowering movement of the support seat 30, further improving the operational convenience and practicality of the height-increasing pad 100.

[0049] The cam 75 is pressed against the support frame 104 and the support frame 102 is pressed down with the help of the pressure relief device 74. The cam 75 is pressed down with the pressure relief device 74 being pressed down with the pressure relief device 74 being pressed down with the pressure relief device 74 being pressed down with the pressure relief device 74 being pressed down with the pressure relief device 74 being pressed down with the pressure relief device 74 being pressed down with the pressure relief device 74 being pressed down with the pressure relief device 74 being pressed down with When the support base 30 is in the second state, the limiting structure 70 can be pressed to release the limiting structure 70 from the limiting fixation on the seat body 31. At this time, the seat body 31 can be driven to extend out of the storage space 151 under the force of the elastic support member 33a restoring the elastic deformation, and the pressing of the limiting structure 70 can be released when the support base 30 is stably in the first state, so that the limiting structure 70 can be automatically reset to the limiting fixation on the seat body 31, thereby realizing convenient operation of adjusting the support base 30 to the first state; and when the height increasing cushion 100 is in the first state, the limiting structure 70 can be pressed to release the fixation on the seat body 31, and then a force can be applied to the seat body 31 to compress the elastic support member 33a to retract it into the storage space 151, and the pressing of the limiting structure 70 can be released when the support base 30 is stably in the second state, so that the limiting structure 70 can be automatically reset to the limiting fixation on the seat body 31. By combining the lifting and lowering adjustment control of the seat body 31 with the limiting structure 70 and the elastic support member 33 a , the convenient operation of the height-increasing pad 100 can be better realized, which is beneficial to further improve the operational convenience and practicality of the height-increasing pad 100 .

[0050] See also Figure 8 and Fig. 9 In the embodiment of the utility model, the connection structure 33 includes a pressure cylinder body 331 and a telescopic push rod 333. The pressure cylinder body 331 is connected to the telescopic push rod 333 by a pipeline, and the telescopic push rod 333 drives the seat body 31 to move up and down.

[0051] In this embodiment, the connection structure 33 may include a pressure cylinder 331 and a telescopic push rod 333. The pressure cylinder 331 may store or generate high-pressure fluid such as high-pressure gas or high-pressure oil. By connecting the pressure cylinder 331 and the telescopic push rod 333 with a pipeline, the pressure cylinder 331 can supply the high-pressure fluid to the telescopic push rod 333 under the action of a fluid supply device such as a pressure pump, so that the telescopic push rod 333 can be extended to act on the seat body 31 and drive the seat body 31 to extend out of the storage space 151, so that the support seat 30 can be stably adjusted to the first state. When the height-enhancing cushion 100 needs to be stored or packed, the high-pressure fluid in the telescopic push rod 333 can be reversed to the pressure cylinder 331 under the gravity of the seat body 31 or the suction effect of the pressure cylinder 331 on the fluid. At this time, the telescopic push rod 333 retracts to drive the seat body 31 to descend into the storage space 151, so that the support seat 30 can be stably adjusted to the second state. Under the action of the connection structure 33 combining the fluid and the push rod, the support seat 30 can be adjusted between the first state or the second state by controlling the flow direction of the high-pressure fluid in the pressure cylinder 331, so as to better realize the automatic control of the height-enhancing cushion 100 and further improve the operational convenience and practicality of the height-enhancing cushion 100.

[0052] Among them, when the height-increasing pad 100 adjusts the lifting and lowering movement of the support seat 30, the limiting structure 70 can be controlled to unlock the limiting fixation of the seat body 31 first, and then the pressure cylinder 331 and the fluid flow direction in the telescopic push rod 333 can be operated to realize the lifting and lowering movement of the seat body 31, so that the limiting structure 70 can avoid when the support seat 30 is lifted and lowered, and provide a better limiting and fixing effect when the support seat 30 is stably in the first state and the second state, thereby ensuring the stable use and storage of the height-increasing pad 100, and further improving the overall structural stability and reliability of the height-increasing pad 100.

[0053] In the embodiment of the utility model, the connection structure 33 includes a motor and a transmission structure. The transmission structure connects the motor and the seat body 31 . The motor drives the transmission structure to operate so that the transmission structure drives the seat body 31 to move up and down.

[0054] In this embodiment, the connection structure 33 can be operated by a motor-driven transmission structure, and then the transmission structure is used to synchronously drive the seat body 31 to move up and down, so that the support seat 30 can be stably adjusted to the first state or the second state. Among them, the transmission structure can be a transmission belt, and the driven wheel and the driving wheel are arranged at intervals in the storage space 151 corresponding to the lifting path of the seat body 31, so that the motor is connected to the driving wheel, and then the driving wheel and the driven wheel can be sleeved by the transmission belt, so that when the motor drives the driving wheel to rotate, the transmission belt can be driven to rotate between the driving wheel and the driven wheel. At this time, by arranging a connecting block on the rotating belt and connecting the connecting block to the seat body 31, the seat body 31 can be driven to rise in the process of the connecting block moving from the position close to the driving wheel at the bottom to the position close to the driven wheel at the top with the rotation of the transmission belt, and the seat body 31 can be driven to fall in the process of the connecting block moving from the position close to the driving wheel to the position close to the driving wheel with the rotation of the transmission belt, so as to achieve stable and reliable adjustment of the first state and the second state of the support seat 30, and further improve the practicality and reliability of the height-increasing pad 100.

[0055] In addition, the transmission structure can also be a cam and connecting rod structure, one end of the connecting rod can be rotatably connected to the bottom of the seat body 31, and the other end of the connecting rod can be abutted against the outer periphery of the cam, and then by connecting the cam to the output shaft of the motor, the motor can drive the cam to rotate, and then when the cam rotates to the raised part abutting the connecting rod, the connecting rod can be stably driven to drive the seat body 31 to rise, and when the cam rotates to the part with a smaller radius abutting the connecting rod, the seat body 31 is driven to fall. The method of using the motor and the transmission structure to drive the support seat 30 to move up and down can better realize the automatic control of the height-increasing pad 100 by controlling the direction and speed of the motor, and further improve the operating convenience and practicality of the height-increasing pad 100.

[0056] Furthermore, the height-increasing pad 100 can also manufacture the limiting structure 70 in an electrically controlled manner, and use an electric push rod or an electromagnetic limiting mechanism to achieve the limiting fixation of the seat body 31 after the lifting and lowering movement. The height-increasing pad 100 can form an integrated control program for the control system of the connecting structure 33 and the control system of the limiting structure 70, which is conducive to making the height-increasing pad 100 more convenient to uniformly control the limiting structure 70 and the connecting structure 33 to cooperate in operation to achieve the adjustment of the support seat 30 between the first state and the second state, better realize the automated control of the height-increasing pad 100, and further improve the operational convenience and practicality of the height-increasing pad 100.

[0057] In an embodiment of the utility model, the connecting structure 33 includes a sliding member arranged in the storage space 151 or on one of the seat bodies 31, and a guide portion arranged on the other one that cooperates with the sliding member, so that the seat body 31 slides up and down along the guide portion in the storage space 151.

[0058] In this embodiment, the sliding member can be a structure such as a slider or a pulley, and the guide part can be a structure such as a guide rail or a recessed slide groove corresponding to the sliding member. The sliding member and the guide part are slidably connected to each other, which can play a certain guiding and limiting role in the movement of the seat body 31 in the storage space 151, so that the seat body 31 can slide up and down in the storage space 151 more stably and reliably, and the support seat 30 can be adjusted between the first state and the second state. At this time, a certain gap can be set between the cushion 10 and the seat body 31, so that when the user needs to adjust the support seat 30 to the first state, he can put his hand into the gap between the cushion 10 and the seat body 31 to extract and drive the seat body 31 to extend out of the storage space 151; or, a handle or a handle can be set on the seat body 31, so that the user can hold the handle or handle to extract and drive the seat body 31 to extend out of the storage space 151; or, an electric control traction structure can be set under the guiding action of the sliding member to connect and drive the seat body 31 to slide up and down, so that the height-increasing pad 100 can better achieve the effect of automatic control. Therefore, the seat body 31 can be more reliably and conveniently operated under the guiding cooperation of the sliding member and the guiding portion, thereby further improving the practicality and reliability of the height-enhancing pad 100 .

[0059] See also Figure 1 and Figure 2 In the embodiment of the utility model, storage spaces 151 are formed on opposite sides of the seat cushion 10, and the height-enhancing cushion 100 includes two support seats 30 and two armrests 50. The two support seats 30 are respectively disposed in the two storage spaces 151, and the two armrests 50 are respectively connected to the two support seats 30.

[0060] In this embodiment, the booster cushion 100 can form storage spaces 151 on opposite sides of the seat cushion 10, and support seats 30 are respectively provided on opposite sides of the seat cushion 10. At the same time, movable and adjustable armrests 50 are respectively provided on the two support seats 30, so that the booster cushion 100 can use the two support seats 30 and the armrests 50 to respectively support the two arms of the passenger, which is conducive to the safety seat to achieve a better wrapping effect for the passenger, effectively prevent the passenger from tipping over from the side of the booster cushion 100, achieve a better protection effect of the booster cushion 100, and further improve the practicality and reliability of the booster cushion 100.

[0061] Among them, the two support seats 30 can be independently arranged in the two storage spaces 151. At this time, the height-increasing cushion 100 can respectively set limiting structures 70 on the seat cushion 10 corresponding to the two support seats 30, so that the height-increasing cushion 100 can respectively perform lifting and lowering operations and limit and fix the two support seats 30, and then during use, according to the user's usage needs, one of the support seats 30 can be operated separately to be in the first state or both support seats 30 can be adjusted to the first state, which is conducive to better improving the practicality and reliability of the height-increasing cushion 100. In addition, a linkage structure may be provided in the seat cushion 10 to connect the two support seats 30, so that the two support seats 30 can be raised and lowered synchronously, which is conducive to better simplifying the adjustment and control operation of the height-increasing cushion 100 and further improving the operational convenience of the height-increasing cushion 100; and since the two support seats 30 are raised and lowered synchronously, a limiting structure 70 may be provided on the seat cushion 10 for a certain support seat 30, and the limiting fixation of the two support seats 30 may be achieved synchronously with the cooperation of the linkage structure, or limiting structures 70 may be provided for the two support seats 30 respectively, so that the support seats 30 can maintain the first state and the second state more stably and reliably, thereby further improving the structural stability and reliability of the height-increasing cushion 100.

[0062] In an embodiment of the utility model, the support seat 30 is provided with one of a limiting protrusion or a snap-on spring sheet, and the limiting structure 70 is the other of the limiting protrusion or the snap-on spring sheet. The limiting protrusion is engaged with the snap-on spring sheet when the support seat 30 is in the first state or the second state.

[0063] In this embodiment, the height-increasing cushion 100 can be provided with a limiting protrusion and a snap-on spring sheet on two corresponding surfaces of the support seat 30 and the seat cushion 10, respectively. The limiting protrusion and the snap-on spring sheet can be snap-on structures provided corresponding to each other. Taking the example of providing a limiting protrusion on the support seat 30 and making the limiting structure 70 on the seat cushion 10 a snap-on spring sheet, two limiting protrusions can be provided on the support seat 30 along the moving path of the support seat 30, or two snap-on spring sheets can be provided on the seat cushion 10 along the moving path of the support seat 30, so that the two limiting protrusions or the two snap-on spring sheets can be provided corresponding to the position of the support seat 30 when it is in the first state or in the second state, so that when the support seat 30 is raised and lowered to the first state or the second state, the snap-on protrusion can be just inserted and fixed in the snap-on spring sheet, so that the limiting structure 70 can stably limit and fix the support seat 30 after the lifting and moving, and further improve the practicality and reliability of the height-increasing cushion 100.

[0064] Among them, since most of the passengers using the safety seat are children, the force exerted by the passengers' arms on the support seat 30 and the armrest 50 is not too large. At this time, by making the elastic force of the snap-fit ​​spring sheet greater than the passenger's arm support force, the snap-fit ​​spring sheet will not undergo elastic deformation when it is subjected to the reaction force of the passenger's arm support when it is engaged with the snap-fit ​​protrusion. However, when the support seat 30 is subjected to a force several times greater than the passenger's arm support force, the snap-fit ​​protrusion can push the snap-fit ​​spring sheet to undergo elastic deformation to loosen the fixation to the snap-fit ​​protrusion, and then the support seat 30 can be loosened from the snap-fit ​​fixation of the snap-fit ​​protrusion and the snap-fit ​​spring sheet under the action of a larger external force, thereby realizing the unlocking movement of the support seat 30, ensuring that the support seat 30 can be stably raised and lowered to the first state and the second state, and the limiting structure 70 can well realize the limiting fixation of the support seat 30 in the first state or the second state, further improving the overall structural stability and reliability of the height-enhancing pad 100.

[0065] See also Figures 3 to 5 In the embodiment of the utility model, a limiting plug hole 311 is provided on the outer peripheral side of the support seat 30, and the limiting structure 70 includes a first latch 71 and a second latch 73, which are arranged at intervals along the moving direction of the support seat 30 and are telescopically arranged between the seat cushion 10 and the support seat 30. The first latch 71 and / or the second latch 73 are correspondingly plugged into the limiting plug hole 311 when the support seat 30 is in the first state or the second state.

[0066] In this embodiment, by providing a limiting plug hole 311 on the outer peripheral side of the support seat 30, and providing a first plug 71 and a second plug 73 at intervals along the moving path of the support seat 30 on the corresponding side wall of the cushion 10, the first plug 71 and the second plug 73 can be plugged into the limiting plug hole 311 to achieve the limiting fixation of the support seat 30 by the limiting structure 70. The limiting plug hole 311 can be a long hole corresponding to the spacing between the first plug 71 and the second plug 73, or can be two plug holes corresponding to the first plug 71 and the second plug 73 respectively plugged, so that when the support seat 30 is in the second state, the first plug 71 and the second plug 73 can be plugged into the support seat 30 at the same time to achieve a better fixing effect, and when the support seat 30 is in the first state, the first plug 71 located at the top can be stably plugged into the limiting plug hole 311, so as to ensure the stable limiting fixation of the support seat 30 by the limiting structure 70 after the lifting and lowering movement.

[0067] By providing a linkage structure on the seat cushion 10 to drive the first latch 71 and the second latch 73 to telescope and move, or by using an electric mechanism to drive the first latch 71 and the second latch 73 to telescope and move, the first latch 71 and the second latch 73 can be stably controlled to retract to avoid the lifting and lowering movement of the support seat 30, and when the support seat 30 stably moves to the first state and the second state, the first latch 71 and / or the second latch 73 can be controlled to extend and plug into the limiting socket 311 to limit and fix the support seat 30, thereby further improving the structural stability and reliability of the height-increasing cushion 100.

[0068] See also Figures 3 to 5 In the embodiment of the utility model, the surface of the seat cushion 10 is provided with an operation hole 17, and the seat cushion 10 is provided with a first movable hole 171 and a second movable hole 173 connecting the operation hole 17 and the storage space 151. The limiting structure 70 also includes a pressing rod 75 and an elastic reset member 77. The pressing rod 75 is movably arranged in the operation hole 17, and the elastic reset member 77 is arranged in the operation hole 17 and connects the pressing rod 75 and the seat cushion 10. The first latch 71 is rotatably connected to the pressing rod 75 and movably penetrates the first movable hole 171. The second latch 73 is rotatably connected to the pressing rod 75 and movably penetrates the second movable hole 173.

[0069] In this embodiment, the operating hole 17 on the seat cushion 10 can be arranged side by side with the storage space 151, and one end of the operating hole 17 can be exposed on the surface of the seat cushion 10. By setting the pressing rod 75 of the limiting structure 70 in the operating hole 17, and making the elastic reset part 77 contact the bottom of the pressing rod 75 and the other end of the operating hole 17, a step can be set on the inner wall of the operating hole 17 to limit the end face of the pressing rod 75 to prevent the pressing rod 75 from slipping out of the operating hole 17.

[0070] When the seat 10 applies force to the pressing rod 75 through the operating hole 17, the pressing rod 75 squeezes the elastic reset member 77 to cause elastic deformation, and simultaneously drives the first latch 71 and the second latch 73 to rotate and retract into the first movable hole 171 and the second movable hole 173. At this time, the limiting plug hole 311 of the support seat 30 is disengaged from the first latch 71 and the second latch 73, so that the limiting structure 70 can avoid the lifting and lowering movement of the support seat 30, so that the support seat 30 can stably extend out of the storage space 151 in the first state or stably retract into the storage space 151 in the second state. When the support seat 30 stably moves to the first state or the second state, the pressure on the pressing rod 75 can be released, so that the elastic reset member 77 can restore its elastic deformation and drive the pressing rod 75 to rise in the operating hole 17, and the pressing rod 75 drives the first latch 71 and the second latch 73 to rotate and extend out of the first movable hole 171 and the second movable hole 173. At this time, the first latch 71 and / or the second latch 73 can be just extended and inserted into the limiting plug hole 311 of the support seat 30, so as to realize the stable limiting fixation of the support seat 30 by the limiting structure 70.

[0071] Therefore, the limiting structure 70 is formed by the linkage structure of the pressing rod 75 and the first latch 71 and the second latch 73, which can realize the convenient operation of locking and unlocking the limit of the support seat 30 on the height-increasing cushion 100, further improving the operational convenience and practicality of the height-increasing cushion 100.

[0072] In the embodiment of the present utility model, the limiting structure 70 further includes a driving device, which connects the first latch 71 and the second latch 73 and drives the first latch 71 or the second latch 73 to telescopically move.

[0073] In this embodiment, the limiting structure 70 can also be provided with a driving device such as a push rod transmission device or an electromagnetic device in the seat cushion 10, and the push rod transmission device can be used to connect the first latch 71 and the second latch 73, so that the first latch 71 and / or the second latch 73 can be driven to move telescopically by driving the push rod to telescope, so as to achieve the telescopic movement of the first latch 71 or the second latch 73 between the seat cushion 10 and the support seat 30, and ensure the limiting fixation of the support seat 30 by the limiting structure 70. Alternatively, corresponding magnets can be provided at the ends of the first latch 71 and the second latch 73, and the first latch 71 and / or the second latch 73 can be driven to move telescopically between the seat cushion 10 and the support seat 30 by changing the magnetic poles through the electromagnetic device, so that the first latch 71 or the second latch 73 can be moved and plugged into the limiting plug hole 311 of the support seat 30 to achieve the limiting fixation of the support seat 30.

[0074] By utilizing the driving device to drive the first latch 71 or the second latch 73 to telescopically move, the automatic control of the limiting structure 70 can be better realized, the overall automatic control effect of the height-increasing pad 100 can be further improved, and the operating convenience and practicality of the height-increasing pad 100 can be further improved.

[0075] See also Figure 1 , Figure 6 and Figure 8 In an embodiment of the present invention, the support base 30 has a first side surface 313 and a second side surface 315 that are opposite to each other. The first side surface 313 is provided with a mounting hole, and the armrest 50 can be slidably inserted into the mounting hole.

[0076] In this embodiment, the support seat 30 can be a seat body 31 or a frame structure with a certain volume, so that the support seat 30 can have a larger supporting volume, which is conducive to better improving the supporting effect of the support seat 30 on the passenger's arm. When the safety seat is set on the carrier seat, the side of the support seat 30 facing away from the carrier seat can be formed as the first side 313 of the support seat 30, and the side of the support seat 30 facing the carrier seat can be formed as the second side 315 of the support seat 30. By setting a mounting hole in the support seat 30 and making the mounting hole pass through the first side surface 313, the armrest 50 can be set in the mounting hole and slidably connected to the support seat 30 through a slide rail or a ball bearing. The armrest 50 can be accommodated in the mounting hole when in a stored state, and can be slid out of the mounting hole and protrude from the first side surface 313 when in an extended state. When the armrest 50 is extended and the end surface of the support seat 30 facing away from the seat cushion 10 cooperates, the supporting area of ​​the height-enhancing cushion 100 for the passenger's arm is better increased, thereby further improving the riding comfort and safety of the safety seat.

[0077] By providing a mounting hole on the first side surface 313 of the support seat 30 to accommodate the armrest 50, the armrest 50 can be better stored inside the support seat 30, which is beneficial to better improve the integrity of the support seat 30 and the armrest 50, and better improve the aesthetics of the height-enhancing cushion 100. At the same time, when passengers are riding, the armrest 50 can be more conveniently pulled out from the first side surface 313 to realize the use and storage of the height-enhancing cushion 100, further improving the operational convenience and practicality of the height-enhancing cushion 100.

[0078] See also Figures 6 to 9 In an embodiment of the utility model, the second side surface 315 is arranged to be inclined relative to the first side surface 313, and the mounting hole passes through the first side surface 313 and the second side surface 315. When the armrest 50 is in the extended state, it protrudes from the first side surface 313, and when the armrest 50 is in the stored state, it protrudes from the second side surface 315.

[0079] In this embodiment, the second side surface 315 of the support seat 30 can be set at a certain angle with the first side surface 313, so that the second side surface 315 can be inclined relative to the first side surface 313. At this time, a certain inclined notch is formed on the side of the support seat 30 facing the carrier seat, which is conducive to utilizing the notch structure to avoid the backrest angle adjustment of the safety seat, or the notch structure can be utilized to avoid the backrest setting of the carrier seat when the safety seat is installed on the carrier seat, thereby ensuring the stable installation and use of the safety seat.

[0080] By forming an inclined notch at the second side surface 315 of the support seat 30, the width of the support seat 30 can be gradually reduced from bottom to top. At this time, the mounting hole can be set as a through hole setting that penetrates the first side surface 313 and the second side surface 315. In order to better ensure the overall supporting area of ​​the height-enhancing pad 100 for the customer's arm, the length of the armrest 50 can be set to be greater than the length of the mounting hole, so that the armrest 50 can slide out of the first side surface 313 and the second side surface 315, thereby realizing the support use and storage of the armrest 50. Therefore, when the armrest 50 needs to be adjusted to the extended state, the armrest 50 can be moved forward and extended out of the first side surface 313 to increase the supporting area of ​​the height-enhancing cushion 100 for the passenger's arm; and when the armrest 50 needs to be adjusted to the stored state, the armrest 50 can be moved backward and extended out of the second side surface 315, so that the armrest 50 can be exposed at the inclined notch on the rear side of the support seat 30, preventing the armrest 50 from interfering with the seat cushion 10 when the support seat 30 is adjusted to the second state, thereby ensuring the stable storage and use of the height-enhancing cushion 100, and further improving the overall structural stability and reliability of the height-enhancing cushion 100.

[0081] Further, see Figures 6 to 9 In the embodiment of the utility model, the first limiting plate 51 and the second limiting plate 53 are respectively provided at both ends of the armrest 50, the first side surface 313 is provided with a first limiting groove around the mounting hole, and the second side surface 315 is provided with a second limiting groove around the mounting hole. The first limiting plate 51 is engaged with the first limiting groove when the armrest 50 is in the storage state, and the second limiting plate 53 is engaged with the second limiting groove when the armrest 50 is in the extended state.

[0082] In this embodiment, by respectively providing a first limiting plate 51 and a second limiting plate 53 at both ends of the armrest 50, a first limiting groove and a second limiting groove can be respectively provided on the first side surface 313 and the second side surface 315, so that when the armrest 50 is in the storage state, the first limiting plate 51 can be clamped in the first limiting groove to achieve the limiting fixation of the armrest 50, and when the armrest 50 is in the extended state, the second limiting plate 53 can be clamped in the second limiting groove to achieve the limiting fixation of the armrest 50, thereby preventing the armrest 50 from escaping from the support seat 30 during the movement and adjustment process, thereby improving the movement stability and reliability of the armrest 50 on the support seat 30, and ensuring the stable use and storage of the height-increasing pad 100. Among them, a magnetic attraction structure or a snap-fit ​​structure can be correspondingly arranged between the first limiting plate 51 and the inner wall of the first limiting groove, and a magnetic attraction structure or a snap-fit ​​structure can be correspondingly arranged between the second limiting plate 53 and the inner wall of the second limiting groove, so that the first limiting plate 51 can be stably clamped in the first limiting groove when it moves into the first limiting groove correspondingly with the armrest 50, and the second limiting plate 53 can be stably clamped in the second limiting groove when it moves into the second limiting groove correspondingly with the armrest 50, thereby ensuring the stable and reliable fixation of the armrest 50 and the support seat 30, and further improving the overall structural stability and reliability of the height-increasing pad 100.

[0083] Furthermore, in an embodiment of the present utility model, the support seat 30 is provided with a telescopic device, which is disposed in the mounting hole and connected to the armrest 50 , and the telescopic device drives the armrest 50 to move.

[0084] In this embodiment, a telescopic device such as an electric guide rail or an electric transmission wheel can be provided in the support base 30, and the armrest 50 can be connected in the mounting hole by using the telescopic device, so that the height-increasing pad 100 can drive the armrest 50 to move forward and backward on the support base 30 by controlling the telescopic device, thereby realizing the adjustment of the armrest 50 between the extended state and the stored state, so that the armrest 50 can realize the function of automatic adjustment on the support base 30, thereby further improving the operational convenience and practicality of the height-increasing pad 100.

[0085] See also Fig.10 In an embodiment of the utility model, the armrest 50 is slidably connected to the end surface of the support seat 30 facing away from the seat cushion 10. When the armrest 50 is in the storage state, it at least partially overlaps with the end surface of the support seat 30. When the armrest 50 is in the extended state, it protrudes from one side of the support seat 30.

[0086] In this embodiment, the armrest 50 can be slidably arranged on the end surface of the support seat 30 facing away from the cushion 10, and a slide rail structure can be arranged between the armrest 50 and the end surface of the support seat 30; or a slide groove can be arranged on the opposite sides of the support seat 30, so that the armrest 50 covers part of the end of the support seat 30, and a slider is arranged on the inner wall of the slide groove of the armrest 50 to slide and engage in the slide groove accordingly, so as to ensure the stable sliding of the armrest 50 on the support seat 30.
