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.

Detailed Implementation

[0028] 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.

[0029] The following is for reference. Figures 1-7 The armrest 1 of a seat according to an embodiment of the present utility model is described.

[0030] like Figures 1-4As 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.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, the base 10 is provided with a first limiting groove 100, the handrail body 20 is rotatably mounted on the base 10, and the handrail body 20 is provided with a plurality of second limiting grooves 200, which are spaced apart circumferentially. It should be noted that the first limiting groove 100 mainly functions as a limiting device in conjunction with other components. The handrail body 20 is rotatably mounted on the base 10. The handrail body 20 is rotatable and has multiple second limiting grooves 200. These multiple second limiting grooves 200 are spaced apart circumferentially. The multiple second limiting grooves 200 mainly function as limiting devices in conjunction with other components. The multiple second limiting grooves 200 can further improve the adjustment options and stability of the handrail body 20, thereby ensuring the adjustment support function of the handrail body 20. The circumferential spacing of the multiple second limiting grooves 200 can avoid interference between them and can also make the distribution range of the multiple second limiting grooves 200 wider, which can also improve the adjustment options and stability of the handrail body 20 to a certain extent.

[0032] like Figure 2 , Figure 4 and Figure 7 As shown, the control component 30 includes a pressing member 300 and a locking member 301. The pressing member 300 extends at least partially beyond the armrest body 20. The pressing member 300 and the locking member 301 are components of the control component 30. 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. The pressing member 300 extends at least partially beyond the armrest body 20, which makes it convenient for the user to press the pressing member 300 and adjust the position of the armrest body 20.

[0033] like Figure 2 , Figure 4 and Figure 7As shown, the locking member 301 includes: a limiting protrusion 302, one end of which is limited and engaged with the first limiting groove 100, and the pressing member 300 is in contact with the other end of the limiting protrusion 302. Moreover, the other end of the limiting protrusion 302 is selectively engaged with one of the plurality of second limiting grooves 200. After pressing the pressing member 300, the other end of the limiting protrusion 302 is released from the limiting engagement with the second limiting groove 200, and the pressing member 300 can slide circumferentially relative to the limiting protrusion 302. It should be noted that the limiting protrusion 302 is a component of the locking member 301. The limiting protrusion 302 mainly fixes the position of the armrest body 20. One end of the limiting protrusion 302 is engaged with the first limiting groove 100, which allows the locking member 301 to be engaged with the base 10. The pressing member 300 is in contact with the other end of the limiting protrusion 302. When the user presses the pressing member 300, the pressing member 300 applies pressure to the limiting protrusion 302, causing it to release from the current limiting groove. Furthermore, the other end of the limiting protrusion 302 selectively engages with one of the multiple second limiting grooves 200. At this time, the user can adjust the height and angle of the armrest body 20 according to their needs. After pressing the pressing member 300, the other end of the limiting protrusion 302 is released from the limiting engagement with the second limiting groove 200, and the pressing member 300 can slide circumferentially relative to the limiting protrusion 302. 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] Therefore, after pressing the pressing member 300, the other end of the limiting protrusion 302 is released from the limiting engagement with the second limiting groove 200, and the pressing member 300 can slide circumferentially relative to the limiting protrusion 302. 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] Specifically, such as Figure 4 As shown, the pressing member 300 includes a sliding part 303 and an opening 304 in the middle of the limiting protrusion 302. The sliding part 303 contacts and engages with the bottom wall of the opening 304. The sliding part 303 mainly functions as a sliding component. The opening 304 in the middle of the limiting protrusion 302 mainly contacts and engages with other components, providing a contact surface for the sliding part 303. When the pressing member 300 is pressed, the other end of the limiting protrusion 302 is released from the limiting engagement with the second limiting groove 200, and the pressing member 300 can slide circumferentially relative to the limiting protrusion 302. 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.

[0036] Among them, such as Figure 5 and Figure 6As shown, the armrest body 20 is also provided with a third limiting groove 201, and the base 10 is also provided with a sliding groove 101. The sliding part 303 is limited to the third limiting groove 201. After the pressing member 300 is pressed, the sliding part 303 is released from the limiting cooperation with the third limiting groove 201, and the sliding part 303 is slidably engaged in the sliding groove 101. The third limiting groove 201 mainly functions to limit the position of the sliding part 303 in conjunction with other components, ensuring that the armrest body 20 remains stable when not in operation. The base 10 is also provided with a sliding groove 101, which mainly provides a sliding path for the sliding part 303. The sliding part 303 is limited and engaged with the third limiting groove 201. At this time, the third limiting groove 201 can lock the position of the sliding part 303, ensuring that the armrest body 20 remains stable when not in operation. After pressing the pressing member 300, the sliding part 303 is released from the limiting engagement with the third limiting groove 201, and the sliding part 303 can slide within the sliding groove 101. At this time, the armrest body 20 can move forward and backward or left and right, increasing the adjustment flexibility of the seat armrest 1.

[0037] In addition, such as Figure 4 As shown, the pressing component 300 further includes a pressing part 305, which is connected to the side of the sliding part 303 away from the limiting protrusion 302. The armrest body 20 is provided with a first through hole 202, and the pressing part 305 extends out of the armrest body 20 through the first through hole 202. The pressing part 305 is an easily accessible operating point for the user, facilitating operation. The pressing part 305 is connected to the side of the sliding part 303 away from the limiting protrusion 302, and the pressing part 305 is connected to the sliding part 303, with the connecting side away from the limiting protrusion 302. The first through hole 202 is mainly used to connect components. The pressing part 305 extends out of the armrest body 20 through the first through hole 202, providing the user with an intuitive and easy-to-operate operating point, allowing the user to easily adjust the position of the armrest body 20, thereby further improving the user experience.

[0038] Of course, such as Figure 2 As shown, the control component 30 also includes a rotating shaft 306, which is fixed to the base 10, and the handrail body 20 is rotatably mounted on the rotating shaft 306. The rotating shaft 306 mainly functions to rotate. 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.

[0039] Furthermore, such as Figure 2 , Figure 4 and Figure 7As shown, the control component 30 also includes an elastic element 307, and the locking element 301 also includes an abutment portion 308. The abutment portion 308 is connected to the side of the limiting protrusion 302 away from the pressing element 300, 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 side of the limiting protrusion 302 away from the pressing element 300. The abutment part 308 is connected to the limiting protrusion 302, and the connecting side is away from the pressing element 300. 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 element 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 engages with one of the multiple second 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.

[0040] In addition, such as Figure 4 and Figure 5 As shown, the base 10 is provided with a second through hole 102, and an abutment portion 308 is provided in the second through hole 102, and the abutment portion 308 is opposite to the rotating shaft 306. The second through hole 102 mainly realizes the connection of components. The abutment portion 308 is provided in the second through hole 102, which realizes the connection between the locking member 301 and the base 10. The abutment portion 308 is opposite to the rotating shaft 306, which provides a stable support point and ensures that the elastic member 307 can work effectively.

[0041] It should be noted that, as Figure 4 and Figure 7 As shown, the abutment portion 308 and the limiting protrusion 302 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.

[0042] In addition, such as Figure 2As 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.
