Description

Technical Field

[0001] This utility model relates to the field of seating technology, and in particular to an armrest and a seat. Background Technology

[0002] In related technologies, the armrest of a seat includes a gravity locking hook hinged to the backrest frame, and a groove is provided on the armrest frame connecting rod. During the process of the backrest frame flipping from the seat cushion to the sitting position, the gravity locking hook, due to its own weight, generates a deflection angle towards the armrest frame connecting rod, causing its hook to engage in the groove of the armrest frame connecting rod. The armrest bracket, along with the backrest frame, flips together. When the armrest bracket, along with the backrest frame, flips to a vertical position, the gravity locking hook, due to its own weight, generates a deflection angle away from the armrest frame connecting rod, causing its hook to disengage from the groove of the armrest frame connecting rod. When the backrest frame, carrying the armrest bracket, flips onto the seat cushion, the gravity locking hook, due to the squeezing action of the armrest frame connecting rod, disengages from the groove of the armrest frame connecting rod. However, existing seat armrests also have significant drawbacks: the armrest surface has few folding structures, mostly offering only cyclic adjustment positions; the armrest cannot be folded downwards, resulting in insufficient comfort when reclining.

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] The following is for reference. Figures 1-6 The armrest 1 of a seat according to an embodiment of the present utility model is described.

[0029] like Figure 1 and Figure 2 As shown, the armrest 1 of the chair according to an embodiment of the present invention includes: a base 10, an armrest body 20, and a control component 30. The base 10 mainly fixes the armrest 1 of the chair to the chair or the chair frame. The armrest body 20 is the main part of the armrest 1 of the chair and is mainly for the user to place their arms. The control component 30 mainly plays a control role and can be used to adjust the position or height of the armrest body 20.

[0030] like Figure 1 and Figure 6 As shown, the handrail body 20 is rotatably mounted on the base 10. The handrail body 20 is provided with multiple first limiting grooves 200, which are spaced apart circumferentially. The handrail body 20 is mounted on the base 10 and is rotatable. The multiple first limiting grooves 200, spaced apart circumferentially, primarily function to limit movement in conjunction with other components. These multiple first limiting grooves further enhance the adjustability and stability of the handrail body 20, ensuring its adjustment and support function. The circumferential spacing of the first limiting grooves 200 prevents interference between them and allows for a wider distribution, further improving the adjustability and stability of the handrail body 20.

[0031] like Figures 2-4 As shown, the control component 30 is disposed within the base 10. The control component 30 includes a pressing member 300 and a locking member 301. One end of the pressing member 300 extends outside the base 10, and the other end of the pressing member 300 is provided with a first inclined mating part 302. The base 10 has an installation space inside, and the control component 30 is disposed within the installation space. This allows for efficient use of the space in the base 10, reducing space occupation and thus solving the space arrangement problem of the armrest 1 of the seat. The control component 30 includes a pressing member 300 and a locking member 301. The pressing member 300 can be used to adjust the position of the armrest body 20, and the locking member 301 can fix the armrest body 20 in a specific position to ensure that it will not move accidentally. One end of the pressing member 300 extends outside the base 10, making it convenient for the user to press the pressing member 300 and adjust the position of the armrest body 20. The other end of the pressing member 300 is provided with a first inclined mating part 302, which can mainly contact and cooperate with other components.

[0032] like Figure 3As shown, the locking member 301 includes: a first main body 303 and a limiting protrusion 304. The limiting protrusion 304 is connected to one end of the first main body 303 and extends out of the base 10. The limiting protrusion 304 selectively engages with one of the plurality of first limiting grooves 200. The other end of the first main body 303 is provided with a second inclined surface engagement part 305, which engages with the first inclined surface engagement part 302. After pressing the pressing member 300, the two ends of the pressing member 300 move in the same direction, and the limiting protrusion 304 releases its limiting engagement with the first limiting groove 200. It should be noted that the first main body 303 and the limiting protrusion 304 are components of the locking member 301. The first main body 303 is the main body of the locking member 301 and can be used to connect and install other components. The limiting protrusion 304 can cooperate with other components for limiting. The limiting protrusion 304 is connected to one end of the first main body 303. The limiting protrusion 304 and the first main body 303 are connected, forming an integral whole, which facilitates the installation and setting of the locking member 301. The limiting protrusion 304 extends outside the base 10, and the limiting protrusion 304 selectively engages with one of the multiple first limiting grooves 200 for limiting. When the armrest body 20 is closed, the user can adjust the height and angle of the armrest body 20 according to their needs. The other end of the first body part 303 is provided with a second inclined surface mating part 305. The second inclined surface mating part 305 can mainly contact and cooperate with other parts. The second inclined surface mating part 305 cooperates with the first inclined surface mating part 302. The second inclined surface mating part 305 and the first inclined surface mating part 302 are in contact and cooperate. After pressing the pressing part 300, the two ends of the pressing part 300 move in the same direction. The limiting protrusion 304 releases the limiting cooperation with the first limiting groove 200. At this time, the armrest 1 of the seat can be folded up or down by one hand, which can improve the overall experience of the seat.

[0033] Therefore, after pressing the pressing member 300, the two ends of the pressing member 300 move in the same direction, and the limiting protrusion 304 releases its limiting engagement with the first limiting groove 200. At this time, the armrest 1 of the seat can be folded up or down by one hand, which can improve the overall experience of the seat.

[0034] Specifically, such as Figure 4As shown, in the pressing direction of the pressing member 300, the cross-sectional area of ​​the first inclined mating part 302 gradually decreases, and the cross-sectional area of ​​the second inclined mating part 305 gradually increases, so that after pressing the pressing member 300, the limiting protrusion 304 moves away from the first limiting groove 200. In the pressing direction of the pressing member 300, the cross-sectional area of ​​the first inclined mating part 302 gradually decreases, and the cross-sectional area of ​​the second inclined mating part 305 gradually increases. Thus, after pressing the pressing member 300, the two ends of the pressing member 300 move in the same direction, and the limiting protrusion 304 moves away from the first limiting groove 200. The limiting protrusion 304 releases its limiting engagement with the first limiting groove 200. At this time, the armrest 1 of the seat can be folded up or down by one hand, which can improve the overall experience of the seat.

[0035] Among them, such as Figure 2 and Figure 3 As shown, the control component 30 also includes: a rotating shaft 306; a first main body 303 is provided with a first through hole 307; the rotating shaft 306 passes through the first through hole 307; and the rotating shaft 306 is fixed to the base 10. The handrail body 20 is rotatably mounted on the rotating shaft 306. The rotating shaft 306 mainly functions to rotate. The first through hole 307 mainly facilitates the connection of components. The rotating shaft 306 passes through the first through hole 307 and the first through hole 305. The rotating shaft 306 is fixed to the base 10 and is fixedly connected to the base 10. The handrail body 20 is rotatably mounted on the rotating shaft 306, thus enabling the handrail body 20 to be rotatably mounted on the base 10.

[0036] In addition, such as Figure 2 and Figure 3As shown, the control component 30 further includes a first elastic element 308, and the locking component 301 further includes a first abutting portion 309. The first abutting portion 309 is connected to the first main body portion 303, and the first elastic element 308 abuts against the first abutting portion 309 and the rotating shaft 306. It should be noted that the first elastic element 308 mainly provides elastic force, playing a role in elastic adjustment. The locking component 301 further includes a first abutting portion 309, which can provide a stable support point for other components. The first abutting portion 309 is connected to the first main body portion 303, and the first abutting portion 309 and the first main body portion 303 are connected. At this time, the first abutting portion 309 and the first main body portion 303 form a whole, facilitating the installation and setting of the locking component 301. The first elastic element 308 abuts against the first abutting portion 309 and the rotating shaft 306. Between the abutment portion 309 and the rotating shaft 306, the two ends of the first elastic member 308 abut against the first abutment portion 309 and the rotating shaft 306 respectively. This further improves the reset mechanism of the locking member 301, ensuring that it can stably and reliably perform locking and unlocking operations. When the pressing member 300 is released, under the action of the first elastic member 308, the locking member 301's limiting protrusion 304 selectively engages with one of the multiple first limiting grooves 200, thereby enabling the armrest 1 of the seat to be fixed at different angles. The first elastic member 308 can be configured as a spring.

[0037] Of course, such as Figures 2-5 As shown, the control component 30 further includes a second elastic element 310, and the pressing component 300 includes a second abutment portion 311. The base 10 is provided with a third abutment portion 312, and the second elastic element 310 abuts between the second abutment portion 311 and the third abutment portion 312. The second elastic element 310 mainly provides elastic force and plays a role in elastic adjustment. The pressing component 300 includes a second abutment portion 311, and the base 10 is provided with a third abutment portion 312. Both the second abutment portion 311 and the third abutment portion 312 can provide stable support points for other components. The second elastic element 310 abuts between the second abutment portion 311 and the third abutment portion 312, with both ends of the second elastic element 310 abutting against the second abutment portion 311 and the third abutment portion 312 respectively. At this time, the second elastic element 310 can drive the pressing component 300 to reset after the pressing component 300 is released. The second elastic element 310 can be configured as a spring.

[0038] Furthermore, such as Figure 3As shown, the pressing member 300 also includes: a second main body 313 and a pressing part 314. The pressing part 314 is connected to one end of the second main body 313, and the first inclined mating part 302 is connected to the other end of the second main body 313. The base 10 is provided with a second through hole 100, and the pressing part 314 extends out of the base 10 through the second through hole 100. The second main body 313 and the pressing part 314 are components of the pressing member 300. The second main body 313 is the main body of the pressing member 300 and can be used to connect and install other components. The pressing part 314 is an easily accessible operating point for the user, facilitating user operation. The pressing part 314 is connected to one end of the second main body 313, and the first inclined mating part 302 is connected to the other end of the second main body 313. Both ends of the second main body 313 are connected to the pressing part 314 and the first inclined mating part 302, respectively. At this time, the pressing part 314, the second main body 313, and the first inclined mating part 302 form a whole, which facilitates the installation and installation of the pressing member 300. The base 10 is provided with a second through hole 100, which mainly enables the connection of components. The pressing part 314 extends out of the base 10 through the second through hole 100, providing the user with an intuitive and easy-to-operate operating point, which facilitates the user to adjust the position of the armrest body 20, thereby further improving the user experience.

[0039] In addition, such as Figure 3 As shown, the base 10 is also provided with a support part 101, which is supported at the other end of the first main body part 303. The support part 101 mainly serves a supporting function. It should be noted that the pressing member 300 is also provided with a slot. The other end of the first main body part 303 is located in the slot, and the support part 101 is supported at the other end of the first main body part 303. This ensures that there is a certain gap between the other end of the first main body part 303 and the bottom wall of the slot in the pressing direction. In this way, after pressing the pressing member 300, only the cooperation between the second inclined surface mating part 305 and the first inclined surface mating part 302 causes the limiting protrusion 304 to move away from the first limiting groove 200, and does not cause the pressing member 300 to press the other end of the first main body part 303 in the pressing direction, thereby causing the first main body part 303 to rotate circumferentially and affecting the normal operation of the handrail 1.

[0040] It should be noted that, as Figures 2-4As shown, the base 10 includes a base body 102 and a cover plate 103. The cover plate 103 covers the base body 102. One end of the pressing member 300 extends out of the cover plate 103, and the limiting protrusion 304 extends out of the base body 102. The base body 102 and the cover plate 103 are components of the base 10. The base body 102 is the main part of the base 10 and can be used to connect and install other components. The cover plate 103 can cover and seal the base 10. The cover plate 103 covers the base body 102, and at this time, the cover plate 103 can cover and seal the base 10. One end of the pressing part 300 extends out of the cover plate 103, so that the pressing part 310 extends out of the base 10. This provides the user with an intuitive and easy-to-operate operating point, which makes it easy for the user to adjust the position of the armrest body 20, thereby further improving the user experience. The limiting protrusion 304 extends out of the base body 102. The limiting protrusion 304 extends out of the base 10, and the limiting protrusion 304 can selectively cooperate with one of the multiple first limiting grooves 200. At this time, the user can adjust the height and angle of the armrest body 20 according to their needs, and can realize the upward or downward folding of the armrest body 20.

[0041] In addition, such as Figures 2-4 As shown, the pressing component 300 is a plastic structural component, and the locking component 301 is a metal structural component. Plastic structural components have advantages such as lightweight and ease of molding, while metal structural components have advantages such as high strength and wear resistance. By making the pressing component 300 a plastic structural component and the locking component 301 a metal structural component, the pressing component 300 and the locking component 301 are more in line with actual working conditions. This combines the advantages of both materials, ensuring both a comfortable user experience and the reliability and durability of the control component 30.
