DETAILED DESCRIPTION

[0036] The preferred embodiments of the present application will be described below with reference to the accompanying drawings, in which:

[0037] It should be noted that in the description of the utility model, the terms "inner", "outer", "upper", "lower", "bottom" and other terms indicating direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is merely for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are for descriptive purposes only and cannot be understood as indicating or implying relative importance.

For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0039] Based on the background technology, the existing storage box under the condition of large load will cause the opening speed to be too fast, which will affect the stability of its operation. The utility model provides a slow-stop mechanism of a storage device and a storage device and a vehicle, which aims to pivotally connect the storage box and the mounting base, and set driving torsional springs, buffer torsional springs, air rope dampers and liquid gear dampers between the two, through the joint action of each force member, the storage box can be stably opened under different load conditions, and the running quality of the storage device and the user's use experience are improved.

[0040] Exemplarily, as Figures 1 to 6 The vehicle of the utility model is provided with a storage cavity in the middle part of the backrest of the rear seat for storing wine, beverages or other articles, and the rear passengers can take and place the articles through the taking and placing opening in the middle part of the backrest. The storage device comprises a storage box 10 and a slow-stop mechanism, the slow-stop mechanism is installed at the bottom of the taking and placing opening, the storage box 10 is pivotally connected with the seat backrest through the slow-stop mechanism, and can rotate between the opening position and the closing position, when the storage box 10 is turned downward to the opening position, it is close to parallel with the seat cushion, at this time, the taking and placing opening is completely opened; when the storage box 10 is turned upward to the closing position, it is close to parallel with the backrest, at this time, the taking and placing opening is completely closed.

[0041] As Figure 1 The inner side of the storage box 10 is provided with a storage grid, which can fix and place articles, further improving the space utilization rate in the storage cavity, and in the process of turning and opening the storage box 10, the stored articles will be turned synchronously with the storage box 10, which will cause the storage box 10 to turn under different load conditions.

[0042] It should be noted that the storage box 10 can be provided separately from the rear central armrest, integrally provided with the rear central armrest, or directly provided as the rear central armrest, which is not limited in the present case and should belong to the protection scope of the present application.

[0043] Specifically, as shown in Figures 1 to 6 the base 1, the fixed shaft 2 is installed on the base 1, the rotating arm 3 is pivotally connected with the fixed shaft 2 and fixedly connected with the storage box 10, and can drive the storage box 10 to rotate between the closed position and the open position, the drive torsional spring 4 has a first end fixedly connected with the base 1 and a second end fixedly connected with the rotating arm 3, and can exert a first torsional force on the rotating arm 3 to rotate from the closed position to the open position, the buffer torsional spring 5 has a first end fixedly connected with the base 1 and a second end fixedly connected with the rotating arm 3, and can exert a second torsional force on the rotating arm 3 to rotate from the open position to the closed position, the air rope damper 6 is fixed on the base 1, and the rope 61 of the air rope damper 6 is connected with the rotating arm 3, and can exert a first damping force on the rotating arm 3 during rotation, and the liquid gear damper 7 is fixed on the base 1, and the resistance gear 71 of the liquid gear damper 7 is drivingly connected with the rotating arm 3, and can exert a second damping force on the rotating arm 3 during rotation.

[0044] Preferably, as shown in Figure 5 the shaft sleeve 9 is pivotally connected with the fixed shaft 2, and the rotating arm 3, the drive torsional spring 4 and the buffer torsional spring 5 are all sleeved on the shaft sleeve 9. The shaft sleeve 9 can be provided as an integral type or a plurality of separate types. By providing the shaft sleeve 9, on the one hand, the rotating arm 3, the drive torsional spring 4 and the buffer torsional spring 5 and other components can be prevented from directly rubbing against the fixed shaft 2 to cause excessive wear, thereby playing a certain protection role; on the other hand, the smoothness of rotation of each component relative to the fixed shaft 2 is improved.

[0045] The storage box 10 is also provided with a locking device (not shown in the figure), which can lock the storage box 10 at different positions. When the storage box 10 is locked at the closed position, the drive torsional spring 4 is in a compressed state and is twisted and deformed, thereby accumulating elastic potential energy, and the buffer torsional spring 5 is in a natural state without force. When it is necessary to open the storage box 10, the locking is only released, and the elastic potential energy of the drive torsional spring 4 is used to drive the rotating arm 3 and the storage box 10 to rotate from the closed position to the open position, thereby providing driving force for the opening of the storage box 10.

[0046] Preferably, as shown in Figure 6As shown, the driving torsional spring 4 comprises a first torsional part 41, a second torsional part 42 and a connecting part 43, the first torsional part 41 and the second torsional part 42 are arranged at both ends of the connecting part 43, the first torsional part 41 and the second torsional part 42 are fixedly connected with both sides of the rotating arm 3 respectively, and the connecting part 43 is fixedly connected with the base 1. Through such arrangement, on the one hand, the torsional strength of the driving torsional spring 4 is increased, so as to ensure that the storage box 10 can be smoothly opened; on the other hand, the first torsion can be applied to both sides of the rotating arm 3 respectively, so that the stress of both sides of the rotating arm 3 is more balanced, and the stability of the rotating arm 3 and the storage box 10 in flip opening is improved.

[0047] In the process of opening the storage box 10, since the buffer torsional spring 5 is gradually compressed, the accumulated elastic potential energy is more and more, and then a greater and greater second torsion can be applied to the storage box 10, at the same time, the first torsion presents a decaying trend due to the gradual release of the elastic potential energy of the driving torsional spring 4, and the result of the two is that the resistance and deceleration of the storage box 10 gradually increase, and finally the end speed of the storage box 10 when reaching the opening position can be reduced, preventing the storage box 10 from continuously accelerating under the action of the first torsion and gravity and causing a large impact and collision.

[0048] However, since the storage box 10 also has a storage function, it is found in actual use that the running speed of the storage box 10 is not the same under different load conditions, especially under heavy load, the acceleration of the downward flip opening is too large, resulting in a large end speed of the storage box 10 when running to the opening position, causing the storage box 10 to collide and vibrate with the rear seat, seriously affecting the opening quality of the storage box 10 and the user's experience.

[0049] Based on the above reasons, the air cord damper 6 is added in the scheme, and the damping characteristic of the air cord damper 6 is utilized, that is, the first damping force generated by the air cord damper 6 is proportional to the speed of the storage box 10, the greater the speed of the storage box 10, the greater the first damping force of the air cord damper 6; the smaller the speed of the storage box 10, the smaller the first damping force of the air cord damper 6.

[0050] In addition, the air cord damper 6 does not intervene throughout the process of the storage box 10 rotating from the closed position to the opening position, but intervenes only when the storage box 10 runs to the rear section, so that the running speed of the storage box 10 in the front section can be ensured, and the speed of the storage box 10 in the rear section can be reduced to prevent the end speed from being too fast and causing impact.

[0051] This design ensures that while the speed of the storage box 10 varies significantly in the first half of its journey due to different loads, the deceleration effect of the air-pulled rope damper 6 in the second half ensures that the final speed of the storage box 10, regardless of load, approaches zero when it reaches the open position. This guarantees a smooth and stable opening process for the storage box 10, preventing excessive speed under heavy loads that could cause impact and damage to the components.

[0052] The liquid gear damper 7 effectively suppresses the shaking and jerking of the rotating arm 3 and the storage box 10 during the flipping process, further improving the smoothness and stability of the operation.

[0053] Due to space constraints, the liquid gear damper 7 cannot be coaxially mounted with the rotating shaft of the rotating arm 3. Therefore, it is necessary to drive the rotating arm 3 through the transmission gear 8 to transmit the second damping force.

[0054] Specifically, such as Figures 3 to 6 As shown, the transmission gear 8 is pivotally connected to the fixed shaft 2 and fixedly connected to the rotating arm 3. The transmission gear 8 also meshes with the resistance gear 71 of the liquid gear damper 7, thereby enabling flexible adjustment of the transmission distance and direction of the second damping force to adapt to the overall structural layout of the storage device and prevent motion interference with other components. Furthermore, to further save space and facilitate the installation of the transmission gear 8, it is preferable to configure the transmission gear 8 as a sector gear.

[0055] Both the transmission gear 8 and the rotating arm 3 are equipped with mutually compatible connection structures. Preferably, one of the transmission gear 8 and the rotating arm 3 has multiple circumferentially spaced limiting blocks 81, and the other has multiple circumferentially spaced limiting grooves 31. The limiting blocks 81 and the limiting grooves 31 are engaged to achieve a fixed connection, thereby ensuring the stable transmission of the second damping force. Furthermore, the limiting blocks 81 and the limiting grooves 31 have a simple structure, stable fit, and are easy to assemble and disassemble quickly.

[0056] In addition to the storage compartment installed in the back of the rear seat, the storage device of this utility model can also be adapted to various storage compartments in the vehicle, such as the glove box in front of the passenger seat.

[0057] Furthermore, the storage device further provided by this utility model, based on the aforementioned slow-stop mechanism, possesses the technical effects of the aforementioned slow-stop mechanism. Compared to the storage device before the improvement, the storage device of this utility model can smoothly and slowly open after placing items of different weights, preventing shaking or collision during the opening process, ensuring the smoothness and stability of opening, and improving the quality of use and user experience.

[0058] Finally, the utility model discloses a vehicle further provided on the basis of the above-mentioned storage device, and the vehicle further has the technical effects of the above-mentioned storage device, and compared with the vehicle before improvement, the comfort and luxury of the vehicle of the utility model are improved.

[0059] Thus, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but the person skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. The person skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the utility model, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
