[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] Embodiment 1

[0036] This embodiment relates to an armrest box assembly, which can adjust the self-opening speed of the elbow pillow cover 1; an exemplary structure thereof is as follows Figure 1 , Figure 2 and Figure 3 shown.

[0037] In general, the armrest box assembly includes a box body, an elbow pillow cover plate 1 which is flippably opened and closed and is arranged on the top of the box body, and a driving unit 2 arranged between the box body and the elbow pillow cover plate 1. The driving unit 2 includes a shift seat 21 fixed on the box body, and an elastic member elastically acting between the shift seat 21 and the elbow pillow cover plate 1. At the same time, the shift seat 21 is provided with a plurality of shift connection parts, and the elastic member can be selectively connected to a certain shift connection part, and can apply a cover-opening driving force to the elbow pillow cover plate 1; changing the shift connection part connected to the elastic member can change the size of the cover-opening driving force.

[0038] Of course, a locking unit should be provided between the elbow pillow cover 1 and the box body. In this embodiment, a locking unit that can be manipulated to be released is provided between the elbow pillow cover 1 and the box body, and the locking unit is used to keep the elbow pillow cover 1 in a closed state. By providing a locking unit between the elbow pillow cover 1 and the box body, the elbow pillow cover 1 can be locked to the box body when closing the elbow pillow cover 1, to prevent the elbow pillow cover 1 from being unable to remain in a closed state due to the action of the drive unit 2; when the elbow pillow cover 1 needs to be opened, the locking unit is manipulated to release its locked state, and the elbow pillow cover 1 will open automatically under the action of the drive unit 2.

[0039] There are of course many options for the specific arrangement of the locking unit, which can be set by referring to the existing self-locking structure of the elbow pillow cover 1. Figure 2As shown, a locking seat 12 is provided at the bottom of the cover body 10 of the elbow pillow cover 1 of the present embodiment, and a locking port 120 is provided on the locking seat 12, and a swingable locking hook is provided on the box body corresponding to the locking port 120, and when the elbow pillow cover 1 is closed in place, the locking hook is hooked into the locking port 120; further, an unlocking button is provided on the outside of the armrest box, and the unlocking button is transmission-connected to the locking hook, and the locking hook can be driven to swing out of the locking port 120 by pressing the unlocking button, thereby releasing the hooking state of the locking hook and the locking port 120, thereby realizing the releasing operation of the locking unit.

[0040] like Figure 2 Combined with Figure 3 , Figure 4 As shown, the elbow rest cover 1 of the present embodiment is hingedly connected to the box body; a hinge hole is provided at the bottom of one side of the cover body 10 of the elbow rest cover 1, and an axle pin 20 is fixedly provided on the box body of the armrest box, and the axle pin 20 is passed through the hinge hole. Specifically, a first connecting seat 14 and a second connecting seat 11 are provided on one side of the bottom of the cover body 10 of the present embodiment, and the hinge holes include a first hinge hole 140 respectively opened on the first connecting seat 14 and a second hinge hole 110 opened on the second connecting seat 11. Of course, the first hinge hole 140 and the second hinge hole 110 should be coaxially arranged. An axle pin can be passed through between the second hinge hole 110 and the box body; the above-mentioned axle pin 20 is passed through the first hinge hole 140. As shown Figure 3 As shown in , the portion of the shaft pin 20 located on the side of the first connecting seat 14 facing away from the shift seat 21 can be fixedly connected to the box body, so that the shaft pin 20 is fixedly arranged on the box body.

[0041] The adoption of a hinged form facilitates structural design, thereby realizing the free flipping action of the elbow pillow cover 1; by arranging a plurality of connecting seats at the bottom of one side of the elbow pillow cover 1, opening hinge holes on the connecting seats, and cooperating with the axle pin 20 fixed on the box body, the elbow pillow cover 1 can be easily installed on the box body.

[0042] There are of course many options for the elastic member, for example, a retaining spring can be used. Figure 4 and Figure 5As shown, the elastic member includes a torsion spring 22 sleeved on the shaft pin 20. The first end 221 of the torsion spring 22 abuts against the elbow pillow cover 1, and the second end 222 of the torsion spring 22 is connected to the gear connection part. In order to improve the abutment stability between the perforation 211 and the elbow pillow cover 1, a baffle 13 perpendicular to the first end 221 is provided on the cover body 10, and a limiting groove 130 is provided on the baffle 13. The first end 221 is limited in the limiting groove 130, so as to ensure the stability and reliability of the opening driving force applied by the first end 221 to the elbow pillow cover 1. Obviously, the elastic member adopts the form of a torsion spring 22 sleeved on the shaft pin 20, which is convenient for technical implementation. Not only is the overall structure simple and efficient, but the torsion spring 22 has a good effect, and the structure is compact, which can reduce the requirements of the drive unit 2 for the installation space.

[0043] In addition, in this embodiment, the shift seat 21 is installed on the shaft pin 20, and a limiting structure for limiting the rotation of the shift seat 21 relative to the shaft pin 20 is provided between the shift seat 21 and the shaft pin 20; each shift connection portion is arranged on the shift seat 21 at intervals along the circumference of the shaft pin 20. Specifically, the limiting structure includes a limiting plane 200 formed on the shaft pin 20, and a through hole 211 opened on the shift seat 21. The limiting plane 200 is arranged parallel to the axis of the shaft pin 20, and the through hole 211 is formed on the shaft pin 20 with a cross-sectional shape at the limiting plane 200, and the shaft pin 20 is inserted in the through hole 211.

[0044] Based on the setting of the shaft pin 20 fixedly mounted on the box body, the shaft pin 20 is used as the basis, and the gear seat 21 is installed on the shaft pin 20, and the limiting structure is used to prevent the gear seat 21 from rotating, thereby providing a well-positioned and stable fulcrum for the second end 222 of the torsion spring 22, so that the gear seat 21 and the torsion spring 22 are compactly arranged on the shaft pin 20, further optimizing the overall layout and structural dimensions of the drive unit 2. By machining a limiting plane 200 arranged parallel to the axis of the shaft pin 20 on the local length or the entire length of the shaft pin 20, the cross section of the portion with the limiting plane 200 will become a non-circular shape, and the through hole 211 is arranged according to the shape. When the shaft pin 20 is inserted into the through hole 211, the rotation of the gear seat 21 relative to the shaft pin 20 will be limited. The above structural scheme is adopted, and the processing structure is simple and convenient for technical implementation.

[0045] There are many design schemes for the specific structural form of the gear seat 21, which can be designed as a block or a column. In this embodiment, the gear seat 21 is generally in a columnar form, which is adapted to the setting of the shaft pin 20. Moreover, the gear seat 21 of this embodiment includes a sleeve 210 and a shift block 212 connected in sequence in the axial direction of the shaft pin 20, and the sleeve 210 is sleeved between the torsion spring 22 and the shaft pin 20; the shift block 212 has a shift portion protruding from the radial direction of the shaft pin 20 to the outside of the sleeve 210, and each gear connection portion is arranged on the shift portion. The gear seat 21 is designed to be composed of two parts: a sleeve 210 and a shift block 212. The sleeve 210 can be used as a bushing for the torsion spring 22. When the inner diameter of the torsion spring 22 is too large compared to the axle pin 20, the sleeve 210 can provide good assembly conditions for the torsion spring 22. By arranging an outwardly protruding shift portion on the shift block 212 and arranging each gear connecting portion on the shift portion, good spatial conditions are provided for the connection between the second end 222 of the torsion spring 22 and the gear connecting portion.

[0046] In addition, there are of course many solutions for the structural form of the shift connection portion. For example, various forms such as slots, jacks, and limit posts can be used to limit the position of the second end 222 of the torsion spring 22. In this embodiment, Figure 5 , Figure 6 and Figure 7 As shown, the gear connection portion is constructed as a gear slot 3 opened on the gear shift portion, and the second end 222 of the torsion spring 22 is at least partially confined in the gear slot 3. The gear connection portion is designed in the form of a groove, which has a simple and reliable structure and is convenient for clamping the second end 222 into the gear slot 3, which is convenient for processing and forming on the gear shift portion.

[0047] Furthermore, in this embodiment, the shifting slot 3 is arranged to pass through the shifting portion in the axial direction of the shaft pin 20; at the same time, the second end portion 222 includes a straight section extending from the main body of the torsion spring 22 toward the shifting portion and entering the shifting slot 3, and a hook section 223 bent and formed at the end of the straight section. The straight section of the second end portion 222 is confined in the shifting slot 3, and the hook section 223 is at least partially located outside the shifting slot 3.

[0048] Each shift slot 3 is designed as a long strip groove that runs through the shifting part, so that the straight section of the second end 222 can directly enter the shift slot 3, making the connection and assembly of the torsion spring 22 and the shift seat 21 more reasonable and efficient. By bending a hook section 223 at the end of the straight section of the second end 222 and making the hook section 223 partially or completely protrude outside the shift slot 3, when switching the position of the second end 222 between the various shift slots 3, the operation will be more convenient, and the hook section 223 can be pulled by tools such as pliers, hooks, screwdrivers, etc. to make the second end 222 detach from the current shift slot 3.

[0049] The specific number of the gear slots 3 can of course be flexibly set. In the present embodiment, there are three gear slots 3, including a first gear slot 301, a second gear slot 302 and a third gear slot 303. The three gear slots 3 are evenly spaced in the circumferential direction of the axle pin 20, thereby forming three gears. Preferably, the angle between two adjacent gear slots 3 can be set to 45°; in specific use, according to the actual opening effect of the elbow pillow cover 1, the gear position of the second end 222 of the torsion spring 22 can be flexibly switched between the three gear slots 3. Figure 7 Combined with Figure 5 As shown, the opening driving force of the torsion spring 22 corresponding to the first gear slot 301, the second gear slot 302 and the third gear slot 303 increases in sequence; if you want to speed up the opening speed of the elbow pillow cover 1, you can switch the second end 222 to the third gear slot 303; if you want to slow down the opening speed of the elbow pillow cover 1, you can switch the second end 222 to the first gear slot 301; when the second end 222 is in the second gear slot 302, the opening speed of the elbow pillow cover 1 is moderate. In this embodiment, the torque difference formed by the opening driving force corresponding to the two adjacent gears acting on the elbow pillow cover 1 is about 0.06N·m.

[0050] To summarize, the armrest box assembly of the present embodiment, by providing a shift seat 21 having a plurality of shift connecting parts in the driving unit 2, and an elastic member acting between the shift seat 21 and the elbow rest cover 1, can not only apply a cover-opening driving force to the elbow rest cover 1 so as to make it open automatically, but also by changing the shift connecting part connected to the elastic member to change the position of the force point of the elastic member on the shift seat 21, the size of the cover-opening driving force can be adjusted, thereby being able to change the self-opening speed of the elbow rest cover 1.

[0053] By setting the above-mentioned driving unit 2 in the armrest box assembly, only simple manual operation is required to adjust the gear position of the torsion spring 22, thereby changing the opening driving force applied by the torsion spring 22 to the elbow pillow cover 1, and then changing the torsional torque acting on the elbow pillow cover 1, and finally realizing the control and adjustment of the opening speed of the elbow pillow cover 1.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
