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.

[0026] 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.

[0027] The following is for reference. Figures 1-5 The armrest 1 of a seat according to an embodiment of the present utility model is described.

[0028] 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's arm to rest on. The control component 30 mainly plays a control role and can be used to adjust the position or height of the armrest body 20.

[0029] like Figure 1 and Figure 5As 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.

[0030] like Figure 2 and 3 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 contact portion 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 contact portion 302, which can mainly contact and cooperate with other components.

[0031] 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 contact portion 302 engages with the other end of the first main body 303. After pressing the pressing member 300, the two ends of the pressing member 300 move in opposite directions, 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 cooperates with one of the multiple first limiting grooves 200 for limiting. At this time, the user can adjust the height of the armrest body 20 according to their needs. The contact part 302 contacts and engages with the other end of the first main body part 303. In this way, the contact part 302 and the first main body part 303 can achieve contact engagement between the pressing member 300 and the locking member 301. After pressing the pressing member 300, the locking member 301 can release its limiting engagement with the first limiting groove 200. That is to say, when the user presses the pressing member 300, the pressing member 300 will apply pressure to the locking member 301, causing it to be released from the current limiting groove. After pressing the pressing member 300, the two ends of the pressing member 300 move in opposite directions, 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.

[0032] Therefore, after pressing the pressing member 300, the two ends of the pressing member 300 move in opposite directions, 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.

[0033] Specifically, such as Figure 3As shown, the first main body 303 is provided with a first through hole 305, and the contact part 302 contacts and engages with the inner wall of the first through hole 305 on the side away from the limiting protrusion 304. The first through hole 305 mainly enables the connection of components. The contact part 302 contacts and engages with the inner wall of the first through hole 305 on the side away from the limiting protrusion 304, and the contact part 302 contacts and engages with the interior of the first through hole 305. Moreover, since the contact side is away from the limiting protrusion 304, the other end of the first main body 303 can also be contacted and engaged.

[0034] Among them, such as Figure 2 and Figure 3 As shown, the control component 30 also includes a rotating shaft 306, which passes through a first through hole 305 and 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. It passes through the first through hole 305 and is fixed to the base 10. The rotating shaft 306 is fixedly connected to the base 10, and 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.

[0035] In addition, such as Figure 2 and Figure 3 As shown, the control component 30 further includes an elastic element 307, and the locking element 301 further includes an abutment portion 308, which is connected to the first main body portion 303, and the elastic element 307 abuts between the abutment portion 308 and the rotating shaft 306. It should be noted that the elastic element 307 can provide elastic force and play a role in elastic adjustment. The locking element 301 also includes an abutment part 308, which can provide a stable support point for other components. The abutment part 308 is connected to the first main body part 303. The abutment part 308 and the first main body part 303 are connected, and at this time, the abutment part 308 and the first main body part 303 form an integral whole, which facilitates the installation and setting of the locking element 301. The elastic element 307 abuts between the abutment part 308 and the rotating shaft 306. Both ends of the elastic element 307 abut against the abutment part 308 and the rotating shaft 306 respectively. This can further improve the reset mechanism of the locking element 301 and ensure that it can perform locking and unlocking operations stably and reliably. When the pressing part 300 is released, under the action of the elastic element 307, the other end of the limiting protrusion 302 of the locking element 301 selectively cooperates with one of the multiple first limiting grooves 200, thereby realizing the fixation of the armrest 1 of the seat at different angles. Among them, the elastic element 307 can be set as a spring.

[0036] Of course, such as Figure 3As shown, the limiting protrusion 304, the first main body 303, and the abutment part 308 are integrally formed structural components. At this time, the locking component 301 is also an integrally formed structural component, making the overall structure more stable and robust, facilitating the installation of the locking component 301, and requiring only one processing mold, which facilitates the production and manufacturing of the locking component 301.

[0037] Furthermore, such as Figure 1 and Figure 3 As shown, the pressing member 300 includes a second main body 309 and a pressing part 310. The pressing part 310 is connected to one end of the second main body 309. The base 10 is provided with a second through hole 100. The pressing part 310 extends out of the base 10 through the second through hole 100. The second main body 309 and the pressing part 310 are components of the pressing member 300. The second main body 309 is the main body of the pressing member 300 and can be used to connect and install other components. The pressing part 310 is an easily accessible operating point for the user, facilitating user operation. The pressing part 310 is connected to one end of the second main body 309, and the pressing part 310 and the second main body 309 are connected. At this time, the pressing part 310 and the second main body 309 form an integral whole, which facilitates the installation and setting 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 310 extends out of the base 10 through the second through hole 100, which provides the user with an intuitive and easy-to-operate operating point, making it easy for the user to adjust the position of the armrest body 20, thereby further improving the user experience.

[0038] In addition, such as Figure 3 As shown, a rotating part 311 is provided in the middle of the second main body 309, and a mating part 101 is provided in the base 10. The rotating part 311 is rotatably disposed in the mating part 101. The rotating part 311 mainly functions to rotate. The rotating part 311 is located in the middle of the second main body 309, and the base 10 is also provided with the mating part 101. The mating part 101 can contact and engage with other components. The rotating part 311 is rotatably disposed in the mating part 101, so that when the pressing member 300 is pressed, the two ends of the pressing member 300 can move in opposite directions.

[0039] It should be noted that, as Figure 2 and Figure 3As 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.

[0040] In addition, such as Figure 2 and Figure 3 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.
