Detailed Implementation

[0022] Numerous specific details are set forth in the following description to provide a full understanding of the invention. However, the invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0023] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0024] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0025] In the description of this invention, references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this invention.

[0026] See Figure 1 As shown in Figure 6, an embodiment of the present invention discloses a door opening device, comprising: Door cover 1, which is used to close the opening of the box body 2.

[0027] A door cover base 21 is disposed at the bottom end of the box body 2, and a shaft 3 is fixedly mounted thereon. The door cover 1 is sleeved on the shaft 3 and pivots along the shaft 3 between a closed position A and an open position C. Optionally, the shaft 3 is mounted on a shaft bracket 211 of the door cover base 21. There are two shaft brackets 211, which are respectively disposed on both sides of the door cover base 21 and fixedly connected to both ends of the shaft 3.

[0028] The opening mechanism includes an opening spring 4 and a clutch 5 sleeved on the shaft. These components are separate from each other, and the opening spring 4 can engage with the clutch 5, which in turn can engage with the door cover 1. Optionally, the clutch 5 can be plate-shaped, sheet-shaped, or block-shaped.

[0029] During the opening process of the door cover 1, the opening spring 4 drives the clutch 5 and the door cover 1 from the closed position to the first intermediate position D between the closed position and the open position, and then the clutch 5 disengages the opening spring 4 from the door cover 1.

[0030] The door opening device disclosed in this embodiment, by setting up a shaft 3, an opening spring 4, a clutch 5 and other structures, makes the action of the opening spring 4 more controllable during the opening process of the door cover 1, thereby improving the user experience.

[0031] It should be noted that the above structure is not limited to applications in vehicles; other scenarios requiring the above-mentioned opening device are within the protection scope of this invention.

[0032] In some embodiments, the clutch is provided with an assembly portion 52 and an engagement portion 51. The clutch 5 is sleeved on the shaft 3 through the assembly portion 52. One side of the engagement portion 51 overlaps with one end of the opening spring 4, and the other side of the engagement portion 51 overlaps with a first engagement portion on the door cover.

[0033] In some embodiments, the clutch 5 abuts against the blocking portion 213 on the door cover base 21 at the first intermediate position D, and the blocking portion 213 prevents the clutch from passing the first intermediate position D.

[0034] according to Figure 1 and Figure 2 As shown, the opening spring 4's rotating end 42 overlaps with the engagement portion 51 of the clutch 5, and the engagement portion 51 overlaps with the first engagement portion 111 on the hinge portion 11. This allows the force to be transmitted through the clutch 5 to the hinge portion 11 after the opening spring 4 is activated, via the aforementioned engagement relationship. The hinge portion 11 then drives the door cover 1 to open and rotate until it reaches the first intermediate position. When the clutch 5 rotates to the first intermediate position D, it is stopped by the blocking portion 213, thus cutting off the work done by the opening spring 4 on the hinge portion 11. Since the blocking portion 213 does not prevent the hinge portion 11 from rotating, the hinge portion 11 and the door cover 1 continue to rotate.

[0035] In some embodiments, the door opening device further includes a damping assembly 6, which includes a damping gear 61 and a damper 62. The damping gear and the damper are respectively disposed on the shaft or the clutch, and the damping gear and the damper are engaged at a second intermediate position E.

[0036] Optional, combined Figure 2 As shown, the damping gear 61 can be fixedly sleeved on the shaft 3, and the damper is fixedly connected to the end of the hinge portion 11. The damping gear 61 is only provided with a gear segment. When the damper moves to the position of engaging with the gear segment, the damping assembly 6 begins to function. Of course, the damping gear 61 can also be provided on the hinge portion 11, while the damper 62 is provided on the shaft 3.

[0037] In some embodiments, the door opening device further includes a buffer spring 7, which is sleeved on the shaft 3, and one end of the buffer spring 7 engages with the hinge portion 11 at a third intermediate position F.

[0038] For details, see Figure 2 As shown, one end of the buffer spring 7 is fixedly connected to the door cover base 21, for example, to the shaft bracket 211 on the door cover base 21. The buffer spring rotating end 71 of the buffer spring 7 is provided with a buffer spring displacement groove 112 or a buffer spring engagement protrusion on the hinge part 11. The buffer spring rotating end 71 can slide on the buffer spring displacement groove 112 when it is not doing work. When it reaches the third intermediate position and engages with the hinge part 11, it begins to slow down the speed of the door cover 1.

[0039] Optionally, referring to Figure 6(a), the aforementioned buffer spring displacement groove 112 can also be replaced by a buffer clutch assembly. The buffer clutch assembly is disposed between the buffer spring 7 and the hinge portion 11, and includes a first clutch 73, a first blocking portion 214, and a second engaging portion 116. The first clutch 73 has a buffer spring rotating end 71 connected in the middle, and a buffer spring fixed end 72 fixedly connected to the shaft frame 211. One end of the first clutch 73 is sleeved on the shaft 3, and the free end of the first clutch 73 is limited by the first blocking portion 214 disposed on the door cover base 21. When the door cover 1 moves to the third intermediate position, as shown in Figure 6(a), the second engaging portion 116 disposed on the hinge portion 11 engages with the first clutch 73, causing the buffer spring 7 to start rotating and doing work, thereby slowing down the speed of the door cover 1. Referring to Figure 6(b), the door cover 1 is in the open position, at which time the buffer spring 7 is rotated and compressed, and the free end of the first clutch 73 is not engaged with the first blocking part 214.

[0040] It should be noted that the first intermediate position D, the second intermediate position E, and the third intermediate position F mentioned above are referenced in [reference needed]. Figure 8 As shown, they can be the same door hinge position or different door hinge positions.

[0041] In some embodiments, combined with Figure 2 As shown, the door cover 1 includes a hinge portion 11, on which a through hole 115 is provided. The door cover 1 is sleeved on the shaft 3 through the through hole 115 on the hinge portion 11, and the hinge portion extends in a direction perpendicular to the center line of the shaft. The through hole is provided on the extension portion 113. In addition, in order to avoid interference and at the same time play a role in shielding and beautifying inside the box body 2, an arc-shaped portion 114 is also provided on the hinge portion 11.

[0042] Optionally, there are two extensions 113, which are arranged in parallel with the corresponding clutch 5.

[0043] In addition, there may be one or two opening springs 4. An opening spring fixing part 212 is provided in the middle of the door cover base 21 for fixing the opening spring fixing end 41.

[0044] It should be noted that during the process of closing the door cover 1 manually, when it is reversed to the first intermediate position, it re-engages with the clutch 5 and the opening spring 4, and drives them back to the closed position A.

[0045] See Figure 7As shown, since the opening end of the door cover is on top and the door cover base 21 is on the bottom, and the storage box is generally tilted, gravity prevents the door cover 1 from opening when the opening spring 4 is in the closed position A. Therefore, process a requires the opening spring to do work against gravity. At position B, the door cover 1 is in a vertical state. After that, gravity begins to play a driving role, entering state b, where gravity becomes the driving force to do work until the opening position C.

[0046] Figure 8 The diagram illustrates the changes in the effect of each force as the door rotates, where D represents the first intermediate position, E the second intermediate position, F the third intermediate position, c the torque provided by the opening spring as the opening angle changes, d the torque provided by gravity as the opening angle changes, e the torque provided by the buffer spring as the opening angle changes, f the torque provided by the damping as the opening angle changes, and g the resultant torque of the above forces as the opening angle changes.

[0047] In one embodiment, see Figure 9 The speed change trend of the door cover as it is shown can be as follows: first, accelerate to start, then rotate at a constant speed when it reaches the third intermediate position F, and then start to decelerate when it reaches the second intermediate position E, until it pivots to the open position, at which point the rotation speed is close to 0.

[0048] During this process, the clutch 5 on shaft 3 first engages with the hinge 11 of the door cover 1, and the opening spring engages with the clutch. After the opening spring 4 pushes the door cover to move a certain angle, the clutch 5 moves to the blocking part (i.e., the blocking part) on the door cover base 21. Figure 2 After the protruding step in the door stops rotating, the clutch 5 and the opening spring 4 disengage from the movement of the door cover. Then, the buffer spring 7 begins to contact the hinge part 11 of the door cover, which acts as a reverse buffer.

[0049] Of course, the above Figure 1-9 The structures described are merely examples and do not constitute a limitation on the scope of protection of this invention.

[0050] In some embodiments, see Figure 10 As shown, the door opening device also includes a latch 10 and a latch driving mechanism. The latch 10 is disposed on the box 2 at one end opposite to the door base 21. The latch driving mechanism includes a motor 8, which can be controlled by a switch in the vehicle or remotely, such as by Bluetooth or other wireless methods, including software applications.

[0051] For details, see Figure 11In the illustrated embodiment, the latch drive mechanism specifically includes a motor 8, preferably a linear motor, on which a linear drive component 81 is mounted. The linear drive component 81 engages with the latch base 9, thereby driving the latch base 9 to reciprocate linearly. The latch base 9 can be positioned above or below the motor 8, and the latch base 9 has a lifting portion 91 near the latch. This lifting portion 91 can be a raised ramp structure. A latch connecting rod 101 is connected to the latch 10, and the latch connecting rod 101 rests on the latch base 9. The lifting portion 91 lifts the latch connecting rod 101 along with the latch, thereby causing the latch 10 to rotate around the latch pivot 102 and disengage from the door cover 1. Optionally, within a few seconds after opening, the motor 8 drives the latch base 9 to return to the locked position.

[0052] See Figure 12 , 13 As shown in Figures 1 and 14, another aspect of the present invention provides a vehicle storage box 100, including a box body 2 and a door cover 1, wherein a door cover opening device according to any one of the above embodiments is provided between the box body 2 and the door cover 1.

[0053] In some alternative embodiments, combined with Figure 13 As shown, the vehicle storage box is also equipped with a pen sleeve structure 110, a document holder structure 120, or a travel tray 130.

[0054] Specifically, the pen cap structure 110 and the document holder support structure 120 are preferably located on the inside of the door cover, while the travel tray 130 is located at the bottom of the box to reduce the impact on the internal space of the storage box. When the travel tray 130 is needed, it can be removed.

[0055] Combination Figure 14 As shown, in one optional embodiment, the accompanying tray is placed at the bottom of the vehicle storage box, and an extraction section is provided on the side of the accompanying tray.

[0056] The pen cap structure and the text support structure are located inside the door cover to facilitate user operation, and the text support structure includes a storage compartment or a mesh pocket.

[0057] Of course, the above embodiments are merely illustrative examples of the design of the travel tray, pen cap structure, and text support structure, and are not specific limitations thereof.

[0058] In another aspect, the present invention provides a vehicle equipped with an in-vehicle storage box according to any of the above embodiments.

[0059] In some embodiments, the in-vehicle storage box is configured to open in at least one of the following ways: touch opening, voice opening, screen control opening, or mobile terminal opening.

[0060] Specifically, the door cover can be opened by using a motor in the vehicle's storage box door opening device to open the latch. Specific methods of motor control include: using a touch switch; enabling voice activation via a vehicle's intelligent control module; enabling activation via function buttons on the vehicle's touchscreen; or remote activation using mobile terminals such as smartphones, tablets, and laptops. Further details will not be provided here, and any method of intelligent control is within the protection scope of this invention.

[0061] In some embodiments, the in-vehicle storage box is located in the rear center console area of ​​the vehicle and is a rear storage box for the user's administrative office or storage purposes.

[0062] It should be noted that although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims of the present invention.
