[0040] In order to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0041] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0042] As Figures 1 to 5 shown, the present disclosure provides an armrest opening structure, which includes a button structure 1, a hook assembly 2 and a flipping plate 3. Among them, the button structure 1 includes a button housing 11 and a button assembly 12. The button assembly 12 is arranged on the button housing 11, and the button housing 11 is used to connect the decorative member 4 of the armrest box. The hook assembly 2 includes a hook 21 and a hook mounting member 22. The hook mounting member 22 is used to connect the armrest skeleton 5 of the armrest box. The hook 21 is rotatably arranged on the hook mounting member 22, and the hook 21 has a pressure plate 211 and a lock tongue 212. One end of the flipping plate 3 is rotatably connected to the button housing 11, and the other end is always supported on the pressure plate 211. The flipping plate 3 has a pressure-receiving protrusion, and the pressure-receiving protrusion is located on the lower side of the moving direction of the button assembly when it is pressed. When the button assembly 12 is pressed, the flipping plate 3 is driven to rotate through the pressure-receiving protrusion to drive the hook 21 to rotate forward, so that the lock tongue 212 is disengaged from the lock hole on the lid 6 of the armrest box.

[0043] Understandably, by providing a button housing 11, a button assembly 12, a locking hook 21, a locking hook mounting member 22, and a flipping plate 3, the button assembly 12 is provided on the button housing 11, the locking hook 21 is rotatably provided on the locking hook mounting member 22, the locking hook 21 has a pressing plate 211 and a locking tongue 212, one end of the flipping plate 3 is rotatably connected to the button housing 11, and the other end is always supported on the pressing plate 211. The flipping plate 3 has a pressure-receiving protrusion, and the pressure-receiving protrusion is located on the lower side of the moving direction of the button assembly 12 when it is pressed. Thus, when the button assembly 12 is pressed, the flipping plate 3 is driven to rotate by pushing the pressure-receiving protrusion, so that the locking hook 21 is driven to rotate forward by the flipping plate 3, thereby changing the linear motion of the button assembly 12 into the rotational motion of the flipping plate 3 to drive the locking hook 21 to rotate. Therefore, the intermediate rod member and the limit for the linear motion of the intermediate rod member can be omitted, the frictional force can be reduced, the problem of easy movement jamming can be improved, and the user experience can be enhanced. Moreover, the flipping plate 3 is rotatably connected to the button housing 11, which can avoid additionally providing a structure to realize the installation of the flipping plate 3 and is beneficial to simplifying the structure.

[0044] It should be noted that the button housing 11 is made of PC / ABS (a thermoplastic plastic formed by combining polycarbonate and acrylonitrile-butadiene-styrene copolymer (ABS)). The flipping plate 3 is made of PA6 (polyamide-6) material. The locking hook 21 is made of POM (Paraformaldehyde, polyoxymethylene) material. The locking hook mounting member 22 is made of PC / ABS (a thermoplastic plastic formed by combining polycarbonate and acrylonitrile-butadiene-styrene copolymer (ABS)).

[0045] As Figure 3 shown, in some embodiments, the above flipping plate 3 is snap-connected to the button housing 11. Installing the flipping plate 3 in a snap-connected manner is convenient for installation, does not require fixing with screws or bolts, and can save costs.

[0046] Exemplarily, in a specific implementation manner, referring to Figure 3 , a card slot is provided on the button housing 11, and a cylindrical shaft is provided at one end of the flipping plate 3. By pressing, the cylindrical shaft is snapped into the card slot and can rotate in the card slot.

[0047] Referring to Figure 2 and Figure 3 , the button assembly 12 includes a button body 121 and a button reset elastic member 122. One end of the button reset elastic member 122 abuts or is connected to the button body 121, and the other end abuts or is connected to the button housing 11. When the button body 121 is pressed, the button reset elastic member 122 is compressed and the flipping plate 3 is driven to rotate.

[0048] Understandably, since the button reset elastic member 122 is provided, when the button body 121 is pressed, it compresses the button reset elastic member 122 and drives the flip plate 3 to rotate. When the external force acting on the button body 121 is removed, that is, when it is no longer pressed, the restoring force of the button reset elastic member 122 returning to its original state will drive the button body 121 to move to the position when it was initially pressed.

[0049] Furthermore, the button body 121 includes a button 1211 and a button support frame 1212. One end of the button support frame 1212 is connected to the button 1211, and the other end extends out of the button housing 11 to drive the flip plate 3. One end of the button reset elastic member 122 abuts against or is connected to the button support frame 1212.

[0050] That is to say, the button reset elastic member 122 is located between the button support frame 1212 and the button housing 11. When the button 1211 is pressed, it drives the button support frame 1212 to move and compresses the button reset elastic member 122, and the end of the button support frame 1212 extending out of the button housing 11 drives the flip plate 3 to rotate.

[0051] It should be noted that a button hole is provided on the decorative member 4 corresponding to the button body 121. When the button body 121 is in the initial position (at this time, the button body 121 is not pressed), the button 1211 can extend out of the button hole to facilitate the pressing operation by the driver and passengers.

[0052] Exemplarily, in a specific implementation manner, the button is made of PC / ABS (a thermoplastic plastic formed by combining Polycarbonate and Acrylonitrile-Butadiene-Styrene copolymer (ABS)), and the surface is treated by an electroplating process. The above-mentioned button support frame 1212 is made of POM material (Polyoxymethylene, polyformaldehyde resin), which has good lubricity and is beneficial to reducing the friction with the button housing 11.

[0053] Furthermore, the button support frame 1212 has a guide post extending along the pressing direction of the button 1211, and the above-mentioned button reset elastic member 122 is sleeved on the guide post. And a relief hole for the guide post to pass through is provided on the button housing 11.

[0054] By providing the guide post, it can play a limiting role on the button reset elastic member 122, enabling the button reset elastic member 122 to contract normally when pressed, so as to ensure that when the pressure on the button 1211 is removed, the button reset elastic member 122 can drive the button back to the position when it was initially pressed. And the setting of the relief hole can prevent the button housing 11 from blocking the movement of the guide post.

[0055] Furthermore, in a specific implementation manner, refer to Figure 2, the button housing 11 is provided with a limiting hole 111 for the button support frame 1212 to pass through, and the axial direction of the limiting hole 111 is the moving direction of the button body 121 when it is pressed.

[0056] Understandably, by setting the limiting hole, the axial direction of the limiting hole 111, which is the pressing direction of the button body 121, can limit the movement of the button support frame 1212, so that the button support frame 1212 always moves in the axial direction of the limiting hole 111, preventing the button body 121 from shifting, which is beneficial to ensuring that the button body 121 smoothly drives the flip plate 3 to rotate when pressed.

[0057] Furthermore, in a specific implementation manner, one end of the above-mentioned button support frame 1212 in contact with the pressing protrusion of the flip plate 3 has a first arc surface in contact with the flip plate 3. By setting the first arc surface, the friction between the button support frame 1212 and the flip plate 3 can be reduced, which is beneficial to the button support frame 1212 driving the flip plate 3 more smoothly and reducing the chance of movement jamming. In addition, an arc surface can also be set at the position where the pressing protrusion of the flip plate 3 contacts the button support frame 1212, and the two arc surfaces cooperate to realize the smooth driving of the flip plate 3 by the button support frame 1212.

[0058] It should be noted that the above-mentioned pressing protrusion can be formed by the structure of the flip plate 3 itself. For example, the flip plate 3 is an approximately S-shaped structure, and the bent part of the flip plate 3 forms the pressing protrusion. Or the pressing protrusion is also a structure provided on the flip plate 3, such as a pressure plate extending towards the button support frame 1212.

[0059] Furthermore, in a specific implementation manner, one end of the flip plate 3 in contact with the pressure plate 211 has a second arc surface in contact with the pressure plate 211. By setting the second arc surface, the friction between the flip plate 3 and the pressure plate 211 can be reduced, which is beneficial to the flip plate 3 driving the pressure plate 211 more smoothly, and then driving the locking hook 21 to rotate forward.

[0060] Refer to Figure 3 , an angle is formed between the pressing plane of the above-mentioned button 1211 and the horizontal plane, and the angle is an acute angle. With such a setting and combined with the setting of the flip plate 3, the pressing direction can be transferred, realizing the change of the angle of force transmission, making the design form diversified and enhancing the comfort of the user when using.

[0061] Such as Figure 2 and Figure 3As shown, the locking hook 21 further has a rotating shaft 213 connected to the pressing plate 211 and the locking tongue 212, and the rotating shaft 213 is rotatably arranged on the locking hook mounting member 22. The locking hook assembly 2 further includes a locking hook return elastic member 23, and the locking hook return elastic member 23 is sleeved on the rotating shaft 213, and the locking hook return elastic member 23 deforms to provide a driving force for the reverse rotation of the locking hook 21.

[0062] Understandably, when the button assembly 12 is pressed, the button support frame 1212 drives the turning plate 3 to rotate, and the turning plate 3 drives the locking hook 21 to rotate forward, so that the locking tongue 212 disengages from the locking hole. During this process, the locking hook return elastic member 23 deforms. When the button assembly 12 loses pressure, the button return elastic member 122 drives the button body 121 to move to the position when it was initially pressed. The turning plate 3 loses the pressure from the button body 121, and at the same time, the pressing plate 211 of the locking hook 21 also loses the pressure from the turning plate 3. In this way, the force for the locking hook return elastic member 23 to return to its original state drives the locking hook 21 to rotate in the reverse direction, that is, drives the locking hook 21 to move in the direction of extending into the locking hole. During this process, the pressing plate 211 pushes the turning plate 3 back to the initial position.

[0063] It should be noted that the rotation direction when the locking hook 21 rotates in the reverse direction is opposite to the rotation direction when the locking hook 21 rotates in the forward direction. Exemplarily, in a specific implementation manner, referring to Figure 3 , when the locking hook 21 rotates in the forward direction, it rotates counterclockwise, then when the locking hook 21 rotates in the reverse direction, it rotates clockwise.

[0064] Exemplarily, in a specific implementation manner, referring to Figure 2 , the above-mentioned locking hook return elastic member 23 is selected as a torsion spring. The torsion spring is sleeved on the rotating shaft 213. One free end of the torsion spring abuts or is connected to the armrest frame 5, and the other free end abuts or is connected to the locking hook mounting member 22.

[0065] Exemplarily, in a specific implementation manner, referring to Figure 3 , a preset angle is formed between the pressing plate 211 and the locking tongue 212, and this preset angle can be set according to the actual installation position and requirements, and no specific limitation is made here.

[0066] As Figure 4 shown, in some embodiments, the above-mentioned locking hooks 21 are provided with two, and both of the two locking hooks 21 are rotatably arranged on the locking hook mounting member 22. Correspondingly, the above-mentioned locking hook return elastic members 23 are also provided with two, and the two locking hook return elastic members 23 are respectively used to drive the two locking hooks 21 to rotate in the reverse direction.

[0067] As shown in the figure, in some embodiments, the above-mentioned locking hook 21 is snap-connected to the locking hook mounting member 22. Installing the locking hook 21 in a snap-connected manner is convenient for installation, without the need to be fixed with screws or bolts, and can save costs.

[0068] For example, in a specific implementation, referring to Figure 2 and Figure 4 The lock hook mounting member 22 is provided with two mounting plates 221 arranged opposite to each other, and the mounting plates 221 are provided with mounting holes. The lock hook 21 has two rotating shafts 213, and the two rotating shafts 213 extend into the two mounting holes respectively. In this way, during installation, the mounting plates 221 can be bent to deform the mounting plates 221 and install the rotating shafts 213 into the mounting holes. In addition, in order to improve the rotation stability of the lock hook 21, the rotating shaft 213 can be set as a stepped shaft, which has a first shaft end and a second shaft end, and the diameter of the second shaft end is larger than the diameter of the first shaft end and larger than the aperture of the mounting hole. The first shaft end extends into the mounting hole, and the lock hook 21 is clamped by the stepped surface formed by the mounting plate 221 and the first shaft end and the second shaft end.

[0069] like Figure 3 and Figure 4 As shown, in some embodiments, the lock hook mounting member 22 is connected to the handrail frame 5 by snap connection. The lock hook mounting member 22 is installed by snap connection, which is convenient for installation and does not need to be fixed by screws or bolts, which can save costs.

[0070] Specifically, the lock hook mounting member 22 is a "U"-shaped structure, and the lock hook mounting member 22 is clamped on the armrest frame 5. One of the lock hook mounting member 22 and the armrest frame 5 is provided with a buckle 222, and the other is provided with a clamping hole, and the buckle 222 is clamped in the clamping hole.

[0071] For example, in a specific implementation, referring to Figure 4 The lock hook mounting member 22 is provided with a buckle 222 , and the armrest frame 5 is provided with a buckle hole.

[0072] The embodiment of the present disclosure also provides an armrest box, including the armrest opening structure in the above embodiment. The armrest box also includes a decorative piece 4, an armrest frame 5 and a box cover 6. The decorative piece 4 is connected to the armrest frame 5, and a button hole for the button 1211 to pass through is opened on the decorative piece 4.

[0073] Reference Figure 4 and Figure 5 , the above-mentioned box cover 6 is provided with two, that is, the armrest box is a split-type armrest box. Correspondingly, the armrest opening structure is provided with two lock hooks 21, that is, the two lock hooks 21 correspond to two lock holes. When the button body 121 is pressed to drive the flip plate 3 to rotate, the flip plate 3 can simultaneously drive the two lock hooks 21 to rotate forward, so that the two lock tongues 212 are respectively disengaged from the corresponding lock holes.

[0074] It should be noted that since the latch hook reset elastic member 23 can drive the latch hook 21 to rotate reversely to the position where the latch tongue 212 extends into the lock hole, the lid 6 can be closed in two ways. One way is that during the closing process of the lid 6, the latch tongue 212 is squeezed to drive the latch hook 21 to rotate forward to avoid the lid 6. After the lid 6 moves to the preset position, the latch hook 21 rotates reversely under the action of the latch hook reset elastic member 23, so that the latch tongue 212 extends into the lock hole to lock the lid 6. Another way is to press the button body 121, drive the latch hook 21 to rotate forward through the flip plate 3 to make the latch tongue 212 avoid the lid 6. After the lid 6 moves to the preset position, release the button body 121. The latch hook 21 rotates reversely under the action of the latch hook reset elastic member 23, so that the latch tongue 212 extends into the lock hole to lock the lid 6, and the button body 121 returns to the position when it was initially pressed under the action of the button reset elastic member 122.

[0075] The present disclosure also provides a vehicle. In some embodiments, the vehicle includes the above-mentioned armrest box. The armrest box is specifically an armrest box on the deputy instrument panel. The vehicle has the technical effects in the above-mentioned embodiments of the armrest box, which will not be elaborated here.

[0076] In other embodiments, the vehicle includes the above-mentioned armrest opening structure. The vehicle has the technical effects in the above-mentioned embodiments of the armrest opening structure, which will not be elaborated here.
