Description

A storage device Technical Field

[0001] The present invention relates to the technical field of article storage for vehicles, and in particular to an article storage device. Background Art

[0002] A roof box is a storage device placed on the roof of a vehicle. It includes a main body and a cover that can be opened and closed relative to each other, with a space for storing items formed between the main body and the cover. Since the roof box is used on the roof of a vehicle, the high-speed movement and bumps of the vehicle place higher demands on the stability of the fastening between the cover and the main body of the roof box, as well as the fluid resistance performance of the roof box. Generally, the main body and cover of a roof box need to be made of hard materials and have a certain streamlined structure. One end of the cover and the main body are rotatably connected by a hinge, and the other end is locked by a metal clip. When closed, the cover and the main body need to be in close contact and there should be no obvious gap to prevent items from falling out of the box. However, because the cover and the main body are made of hard materials, the cover, which is in close contact with the main body when closed, is easily abutted and interfered with by the main body when it is rotated to open, making it difficult to open or opening at a small angle, making it inconvenient to take items in and out. In this regard, one solution in the prior art is to set the side walls of the body to be recessed relative to the edges of the body to form a clearance space to prevent the cover from abutting against the body when the lid is opened. This takes up space in the box and affects the streamlined design of the body.

[0003] Therefore, it is necessary to propose a novel roof storage device to solve the above-mentioned problems. Summary of the Invention

[0023] Referring to Figures 1 to 4 , the present application provides a storage device 100 suitable for attachment to a vehicle, particularly a roof box mounted on the roof of a vehicle. The storage device 100 includes a body 1 and a lid 2, connected by a hinge mechanism 3. The hinge mechanism 3 allows the lid 2 to rotate open and close relative to at least one edge of the body 1. In some embodiments, the hinge mechanism 3 is disposed at two opposing edges of the storage device 100. When the lid 2 is opened, the hinge mechanism 3 at one edge is released from the body 1 or lid 2, allowing the lid 2 to rotate about the hinge mechanism 3 at the other edge. In this embodiment, the hinge mechanism 3 is disposed at two opposing edges of the lid 2. The body 1 is provided with a locking seat 11 that corresponds to the hinge mechanism 3. The hinge mechanism 3 can lock with the locking seat 11 to form a rotational connection mechanism, allowing the lid 2 to rotate open relative to the body 1 about the hinge mechanism 3. The hinge mechanism 3 can also be unlocked from the locking seat 11 to serve as the opening side of the cover 2 when it is opened relative to the body 1. That is, in this embodiment, the cover 2 can be opened from both sides of the body 1 to facilitate use by the user.

[0024] As shown in Figures 5 to 9, the hinge mechanism 3 includes a first link member 31 and a second link member 32. The first link member 31 is pivotally connected between the body 1 and the cover 2. The first link member 31 has at least two ends, pivotally connected to the body 1 and the cover 2 via a first pivot axis 41 and a second pivot axis 42, respectively. The second link member 32 has at least two ends, pivotally connected to the body 1 and the cover 2 via a third pivot axis 43 and a fourth pivot axis 42, respectively. The distance between the first pivot axis 41 and the third pivot axis 43 remains constant, and the distance between the second pivot axis 42 and the fourth pivot axis 44 remains constant. The body 1, the cover 2, the first link member 31, and the second link member 32 form a four-bar linkage. When the cover 2 rotates open relative to the body 1, the first link member 31 and the second link member 32 rotate relative to the body 1 and the cover 2, respectively. The distance between the fourth pivot axis 44 and the first pivot axis 41 increases, causing the cover 2 to move away from the body 1. The storage device 100 provided in the present application includes a hinge mechanism 3 that constitutes a four-bar linkage mechanism, so that the cover 2 does not interfere with the main body 1 when opened relative to the main body 1 without providing an inward avoidance space on the main body 1.

[0025] The hinge mechanism 3 further includes a first base member 33 configured to be releasably connected to one of the body 1 and the cover 2. In this embodiment, the first base member 33 is releasably connected to the body 1. A first pivot axis 41 and a third pivot axis 43 are each connected to the first base member 33, so that the first pivot axis 41, the third pivot axis 43, and the first base member 33 can be integrally released from the body 1. The distance between the first pivot axis 41 and the third pivot axis 43 is defined by the first base member 33 and remains constant. In this embodiment, since one end of the hinge mechanism 3 connected to the body 1 needs to be configured to be releasable from the locking seat 11 of the body 1 to achieve opening and locking of the cover 2 relative to the body 1, if the first pivot axis 41 and the third pivot axis 43 included in the hinge mechanism 3 are independently connected to the body 1, the distance between the first pivot axis 41 and the third pivot axis 43 will change after the hinge mechanism 3 is released from the locking seat 11 on the body 1, affecting the uniqueness of the motion path of the four-bar linkage and thus affecting the opening and closing process of the cover 2. Therefore, the provision of the first base member 33 in this application can limit the distance between the first pivot axis 41 and the third pivot axis 43 to remain unchanged and facilitate the integral release of the hinge mechanism 3 from the locking seat 11. In this embodiment, the locking seat 11 includes a locking hook 111, and at least one of the first pivot axis 41 and the third pivot axis 43 is configured as a locking pin to be pivotally locked with the locking hook 111. After locking, the locking pin and the locking hook 111 form one of the pivot axes during the movement of the hinge mechanism 3 .

[0026] The hinge mechanism 3 also includes a second base member 34 opposite the first base member 33. The second pivot axis 42 and the fourth pivot axis 44 are pivotally connected to the second base member 34. During the lid opening process, one of the first base member 33 and the second base member 34 is fixedly connected to the body 1, and the other is fixedly connected to the lid 2. A sliding guide is provided between at least one of the first link member 31 and the second link member 32 and at least one of the first base member 33 and the second base member 34. In this embodiment, a sliding guide is provided between the first link member 31 and the second base member 34. The sliding guide includes an arcuate groove 340 and a guide shaft 45 that slides within the arcuate groove 340. The second base member 34 includes a top plate 341 fixedly connected to the body 1 or the lid 2, and a side plate 342 extending from a side edge of the top plate 341. The arcuate groove 340 is formed on the side plate 342 of the second base member 34. The sliding guide can guide the relative movement between the first connecting rod member 31 and the second base member 34, making the relative movement between the two more stable. The side panels 342 are arranged in opposite directions. The first connecting rod member 31 and the second connecting rod member 32 each include two oppositely arranged pivotally connected side panels, which are pivotally connected to the two side panels 342 of the second base member 34.

[0027] The second base member 34 is fixedly connected to the body 1 or cover 2, with a spacer 36 disposed between the second base member 34 and the body 1 or cover 2. By using spacers 36 of varying thicknesses, the height of the hinge mechanism 3 when connected to the body 1 or cover 2 can be adjusted, thereby accommodating bodies 1 and covers 2 of varying sizes and shapes, and enhancing the versatility of the hinge mechanism 3.

[0028] Continuing to refer to Figures 5 to 9 , the first link member 31 is a single-piece component comprising a base plate 311 and pivoting side plates 312 extending from opposite sides of the base plate 311. The second link member 32 is a split component comprising two separate portions disposed at either end of the third pivot axis 43 and the fourth pivot axis 44. The second link member 32 is closer to the edge than the first link member 31. The second link member 32 is bent to form a clearance zone toward the edge to prevent contact with the edge during the opening of the lid 2. In this embodiment, the second link member 32 is generally L-shaped, and the roughly right-angled space formed inside the L-shape serves as the clearance zone. As shown in Figures 4 and 6 , the second link member 32 abuts the edge of the main body 1 to define the maximum opening position of the lid 2. The distance between the third pivot axis 43 and the fourth pivot axis 44 on the second link member 32 is smaller than the distance between the first pivot axis 41 and the second pivot axis 42 on the first link member 31, so that during the opening process, a suitable opening angle can be formed between the cover body 2 and the body 1. In one embodiment, the distance between the first pivot axis 41 and the second pivot axis 42 is 7-9 cm, the distance between the third pivot axis 43 and the fourth pivot axis 44 is 4-6 cm, the distance between the first pivot axis 41 and the third pivot axis 43 is 1.5-5.3 cm, and the distance between the second pivot axis 42 and the fourth pivot axis 44 is 3.5-5.5 cm.

[0029] Referring to Figures 5, 6, 8, and 9, the hinge mechanism 3 further includes a force storage member 35. The force storage member 35 is configured such that, when the hinge mechanism 3 is released from the body 1 or the lid 2, the force storage member 35 maintains the hinge mechanism 3 in a position suitable for locking with the locking hook 111 on the body 1 or the lid 2 when the lid 2 is closed. Specifically, the force storage member 35 is used to define the relative positions of the first link member 31 and the second link member 32 when the hinge mechanism 3 is released from the locking seat 11. The force storage member 35 is further configured such that, when the lid 2 rotates open about the hinge mechanism 3, the force storage member 35 is in a force storage state where it elastically deforms to generate an elastic restoring force. The elastic force generated by the force storage member 35 helps provide an auxiliary closing force when the lid 2 is closed. In this embodiment, the force storage member 35 is a spring, one end of which is connected to the fourth pivot shaft 44 and the other end is connected to the first connecting rod member 31. When the cover body 2 is in the open state, the force storage member is in a tensioned and force-storing state. The force storage member 35 is a tension spring, and its two ends are connecting rings. The connecting ring at one end is mounted on the fourth pivot shaft 44, and the connecting ring at the other end is mounted on the connecting piece 313 of the first connecting rod member 31. The connecting piece 313 is bent and extended from the base plate 311 of the first connecting rod member 31. The connecting piece 313 is bent at an angle that facilitates connection with the connecting ring on the tension spring, and a connecting hole is provided on the connecting piece 313 for the connecting ring to be hooked into the connecting hole for connection.

[0030] The force storage member 35 is limited to the spring form in this embodiment. In other embodiments of the force storage member 35 (not shown in the figure), the force storage member 35 can also be replaced by components made of other elastic materials, such as spring sheets, elastic plastics, elastic silicone rubber, etc.

[0031] Referring to Figures 10 and 11 , in another embodiment of the hinge mechanism 3, the second base member 34 is constructed as a plastic block and is directly fixed to the cover 2 or the body 1. Specifically, the second base member 34 and the spacer 36 of the previous embodiment are integrated into one body to form the second base member 34 of this embodiment. The remaining components of this embodiment are the same as those of the previous embodiment and will not be further described here.

[0032] It should be noted that although the specific embodiments and drawings of this application are described using the example of the locking seat 11 being set on the main body 1 and the hinge mechanism 3 being connected to the cover body 2, it should be understood that the same effect can be achieved by setting the locking seat 11 on the cover body 2 and the hinge mechanism 3 on the main body 1, which is also an embodiment included in this application.

[0033] Please refer to Figures 1 to 6. The usage process is as follows: when the cover body 2 is in the closed state, after releasing the lock hook 111 on the locking seat 11, the cover body 2 can be lifted upward on the side edge of the released lock, and the cover body 2 will rotate with the hinge mechanism 3 provided at the other side edge opposite to the side edge as the rotation point, and the hinge mechanism 3 moves from the state shown in Figure 5 to the state shown in Figure 6 to achieve opening of the cover; when the cover body 2 is in the open state, press downward on the open side edge of the cover body 2, and the cover body 2 will rotate with the hinge mechanism 3 as the rotation point, and the hinge mechanism 3 moves from the state shown in Figure 6 to the state shown in Figure 5 until the first pivot shaft 41 on the hinge mechanism 3 provided at the open side edge is locked by the lock hook 111 on the locking seat 11, and closing is achieved.

[0034] In summary, it can be seen from the above description that the present invention achieves the following technical effects:

[0035] The storage device provided in the present application has a hinge mechanism 3, which constitutes a four-bar linkage mechanism, so that there is no need to set an inward avoidance space on the main body 1, so that the cover body 2 will not interfere with the main body 1 when it is opened relative to the main body 1.

[0036] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0037] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0038] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is to facilitate the distinction between corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0039] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
