Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, the use of directional words such as "upper and lower" and "left and right" is defined in the actual use process unless otherwise stated. For example, the vertically swingable swing link 11 and the vertically extending elongated hole 41 formed in the second apron 4 are defined in the upper and lower directions in the use of the vehicle. The terms "first," "second," and the like as used in this disclosure are used to distinguish one element from another, and do not denote any order or importance. The following description refers to the accompanying drawings in which like references indicate the same or similar elements in different figures.

Referring first to fig. 1, in the related art, in order to enable the closure to be locked or unlocked, the cargo box locking mechanism includes a click plate 5 having an opening provided on the first closure 3 and a turn lever 6 provided on the second closure 4. The turning rod 6 comprises a turning shaft 61 extending into the second enclosing plate 4 along the side and a handle 62, and the handle 62 can be axially turned around the turning shaft 61 to be locked in the opening of the clamping plate 5 or separated from the clamping interface. When the locking mechanism needs to be locked or unlocked, the handle 62 needs to be manually rotated to overcome mechanical resistance to unlock or lock. This process is high in mechanical resistance, and as the time of use increases, the mechanical resistance may further increase due to aging such as rusting.

In order to solve the problems of great self weight and large use resistance of the cargo box locking mechanism in the related art, the disclosure provides a cargo box locking mechanism which comprises a locking piece 2 and a moving piece, and referring to fig. 2 and 3. Locking piece 2 sets up on first bounding wall 3, and the motion sets up on second bounding wall 4, and the motion can the lock make this locking mechanism be in the state of locking on locking piece 2. The first enclosing plate 3 and the second enclosing plate 4 are named for distinguishing only and can be reasonably arranged according to actual use conditions. For example: the first enclosing plate 3 can be arranged as a rear enclosing plate, and the second enclosing plate 4 is a side enclosing plate; the first enclosing plate 3 can be a side enclosing plate, and the second enclosing plate 4 can be a back enclosing plate. At least one of the first enclosing plate 3 and the second enclosing plate 4 can be turned over, so that a user can conveniently take and place goods. In this embodiment the first and second closure panels 3, 4 are locked to each other by a container locking mechanism. Further, according to another embodiment, one of the lock member 2 and the moving member is fixed to a surrounding plate (the first surrounding plate 3 or the second surrounding plate 4), and the other may be fixed to the vehicle body, in which case the first surrounding plate 3 and the second surrounding plate 4 are not connected. The disclosure will be described herein only with reference to the first embodiment (i.e., the latch 2 is disposed on the first enclosure 3 and the mover is disposed on the second enclosure 4).

Referring to fig. 2 and 3, the moving member may include a fixed shaft 12 fixed to the second enclosing plate 4 and a swing link 11 rotatably connected to the fixed shaft 12 up and down, and the locking member 2 may be formed with a passage through which the swing link 11 swings up and down; the swing rod 11 can be connected with the fixed shaft 12 on the second enclosing plate 4 in a vertically rotating mode, the process of vertically swinging is the process of opening or locking the second enclosing plate 4, and the channel is used for limiting the movement direction of the swing rod 11 and preventing the swing rod 11 from laterally separating. For example, in the case where the locking element 2 described below is configured as a U-shaped plate, the opening of the U-shaped plate forms a pivoting channel of the rocker 11.

The embodiment of the present disclosure drives the swing link 11 to rotate by the elastic force of the spring, instead of manually snapping, specifically, the fixed shaft 12 is sleeved with a first torsion spring 121 and a second torsion spring 122, one end of each of the first torsion spring 121 and the second torsion spring 122 is connected to the fixed shaft 12, and the other end of each of the first torsion spring 121 and the second torsion spring 122 is connected to the swing link 11. The first torsion spring 121 and the second torsion spring 122 are configured to: in the locking position, the first torsion spring 121 is torsionally deformed and has an elastic force that enables the swing link 11 to be buckled with the locking member 2, and the second torsion spring 122 is in a balanced state; in the open position, the first torsion spring 121 is in a state of equilibrium, and the second torsion spring 122 is torsionally deformed and has an elastic force to disengage the swing lever 11 from the lock member 2. The container locking mechanism further comprises a first limiting part capable of limiting the upper part of the swing rod 11 and a second limiting part capable of limiting the lower part of the swing rod 11.

Because one end of each of the first torsion spring 121 and the second torsion spring 122 is connected and fixed on the fixed shaft 12, and the other end of each of the first torsion spring 121 and the second torsion spring 122 is connected on the swing link 11, the positions of the first torsion spring 121 and the second torsion spring 122 connected on the swing link 11 can be changed, so that two different torsion forces of the first torsion spring 121 and the second torsion spring 122 are matched, the swing link 11 is driven to rotate up and down, the position state of the swing link 11 is changed, and the locking or the opening between the second enclosing plate 4 where the swing link 11 is located and the first enclosing plate 3 where the locking member 2 is located is further realized.

Specifically, when one end of the first torsion spring 121 is connected to the first position on the swing link 11, and one end of the second torsion spring 122 is connected to the second position on the swing link 11, the first torsion spring 121 is torsionally deformed and has an elastic force that enables the swing link 11 to be buckled with the locking member 2, and the second torsion spring 122 is in an unstressed balanced state, so that the cargo box locking mechanism can be kept at the locking position. In the locking position, the first limiting part or the second limiting part is matched with the channel, so that the swing rod 11 can be limited to enable the second enclosing plate 4 to keep a vertical state and not to turn over. When the swing link 11 has a special-shaped structure such as a below-described inflected portion 113, the rotation of the first enclosing plate 3 can be restricted.

When the first torsion spring 121 is connected to the third position of the swing rod 11 by an external acting force and the second torsion spring 122 is connected to the fourth position of the swing rod 11 at the same time, the first torsion spring 121 is in a balanced state, the second torsion spring 122 is twisted and deformed and has an elastic force which enables the swing rod 11 to be separated from the locking piece 2, so that the cargo box locking mechanism can be kept at an opening position, and the second enclosing plate 4 can rotate freely. When the swing link 11 has, for example, a below-described inflected portion 113, the first enclosing plate 3 can also be freely rotated.

The switching between the first position and the third position and the switching between the second position and the fourth position may be implemented in any suitable manner. In the present disclosure, referring to fig. 3 to 5, according to an embodiment, the swing link 11 may include a rod 112 and a rotating disc 111 rotatably connected to the rod 112, and the first torsion spring 121 and the second torsion spring 122 are respectively connected to the rotating disc 111 to be capable of driving the rod 112 to swing through the rotating disc 111; the container locking mechanism further comprises a drive member 13 for driving the rotary disc 111 to rotate. The swing link 11 of the present disclosure is provided with a rotating disc 111, the link body 112 and the first torsion spring 121 and the second torsion spring 122 on the fixed shaft 12 are connected together through the rotating disc 111, the connecting positions of the first torsion spring 121 and the second torsion spring 122 with the link body 112 are changed through the rotation of the rotating disc 111, and then the twisting force of the first torsion spring 121 and the second torsion spring 122 is changed, so that the swing link body 112 can swing up and down. In addition, in order to conveniently realize the rotation of the rotating disc 111, the cargo box locking mechanism can be further provided with a driving piece 13 for driving the rotation of the rotating disc 111. Specifically, the driving member 13 drives the rotating disc 111 to rotate for the first time, so as to change the twisting force of the first torsion spring 121 and the second torsion spring 122, thereby driving the rotating disc 111 to rotate for the second time, which can drive the rod 112 to swing, i.e. the direction of the second rotation is the same as the direction of the swing rod 11 swinging up and down. The driving force for the first rotation is from the outside of the whole device, and may be manually operated, and the driving force for the second rotation is from the inside of the whole device, specifically, the first torsion spring 121 and the second torsion spring 122. For example, with reference to fig. 4 and 5, the first rotation of the rotary disk 111, in the direction of the drawing, rotates about its own axis of rotation 114 of the rotary disk 111; the second rotation of the rotating disk 111 is not in the plane of the drawing but rotates around the fixed shaft 2.

The present disclosure is not limited to the structure of the driving member 13. According to one embodiment, referring to fig. 4 and 5, the driving member 13 may include a button 131 capable of bi-directional swing and a first link 132 and a second link 133 respectively connected to the button 131. The other ends of the first link 132 and the second link 133 are respectively connected to the rotary disc 111, and the first link 132 and the second link 133 drive the bidirectional rotation of the rotary disc 111 by pressing the button 131.

The position shown in fig. 4 is a locked position, and the position shown in fig. 5 is an open position. When the cargo box locking mechanism is in the locking position, referring to fig. 4, the first torsion spring 121 is deformed in a twisting manner and has an elastic force that enables the swing link 11 to be engaged with the locking member 2, and the second torsion spring 122 is in a balanced state. At this time, on the one hand, the first torsion spring 121 has a first resilience force to return to the equilibrium state, and the first resilience force makes the rod body 112 continue to fasten the locking member 2, so that the cargo box locking mechanism can be maintained at the locking position. When the state of the locking mechanism needs to be changed, the button 131 is pressed, and during the pressing process, the pressing force is transmitted to the rotating disc 111 through the first connecting rod 132 and the second connecting rod 133, so that the rotating disc 111 is driven to rotate, and meanwhile, the relative positions of the first torsion spring 121 and the second torsion spring 122 and the rod body 112 at the locking position are changed (namely, the relative positions of the rotating disc 111 and the rod body 112 are changed). During this change of relative position, the first torsion spring 121 gradually returns to the equilibrium state, while the second torsion spring 122 is in the process of increasing torsion, and at this time the second torsion spring 122 has a second resilience force, which has a tendency to disengage the rod body 112 from the lock member 2 and keep the rod body 112 disengaged from the lock member 2, so that after the button 131 is released, the container locking mechanism can maintain the position shown in fig. 5, which keeps the container locking mechanism in the open position.

Since the process of switching the container locking mechanism from the open position to the locked position is exactly the reverse of the above process, this will not be explained repeatedly.

The present disclosure does not limit the connection manner of the inner portion of the swing link 11 and the connection manner of the swing link 11 and the fixed shaft 12. According to one embodiment, referring to fig. 3, the fixed shaft 12 may radially penetrate the rod body 112, the rotating disc 111 (not shown in fig. 3) is coaxially installed inside the rod body 112, and the first link 132 and the second link 133 respectively radially protrude inside the rod body 112 to be connected with the rotating disc 111; both ends of the first link 132 are rotatably connected to the button 131 and the rotary disk 111, respectively, and both ends of the second link 133 are rotatably connected to the button 131 and the rotary disk 111, respectively. Here, the rotating disc 111 is coaxially installed inside the rod body 112, so that the connection between the rotating disc 111 and the rod body 112 is firmer, the falling off of the rotating disc 111 during rotation is avoided, and the use process of the container locking mechanism is more stable. For example, according to one embodiment, the rod body 112 may include a solid rod portion and a hollow rod portion, an end surface of the solid rod portion is protruded to form a rotation shaft on which the rotation disk 111 is coaxially mounted, and the rotation disk 111 is accommodated inside the hollow rod portion. The fixed shaft 12 can radially penetrate through the rod body 112, and one end of each of the first torsion spring 121 and the second torsion spring 122 sleeved on the fixed shaft 12 is connected to the rotating disc 111 inside the rod body 12. The first link 132 and the second link 133 respectively radially extend into the rod 112 to be connected with the rotating disc 111, so that the rod 112 can limit the moving paths of the first link 132 and the second link 133, and the risk of falling off or damage of the first link 132 and the second link 133 is reduced. Both ends of the first link 132 are rotatably connected to the button 131 and the rotary plate 111, respectively, and both ends of the second link 133 are rotatably connected to the button 131 and the rotary plate 111, respectively, so that smooth movement of the first link 132 and the second link 133 can be ensured. Referring to fig. 4 and 5, in the locked position and the open position, an angle between the first link 132 and the push button 131 and the rotary plate 111 is changed, and an angle between the second link 133 and the push button 131 and the rotary plate 111 is also changed.

The position where the button 131 is provided is not limited in this disclosure. For example, referring to fig. 2, the button 131 may be mounted on the second enclosing plate 4, and the top of the button 131 protrudes upward from the second enclosing plate 4, specifically, the button 131 may be rotatably connected to the second enclosing plate 4, and pressing the button 131 may rotate the button 131 relative to the second enclosing plate 4. Providing the button 131 in a position protruding from the second shroud may make the push actuation process easier to operate.

The present disclosure does not limit the connection manner of the first torsion spring 121, the second torsion spring 122 and the rotating disk 111. According to an embodiment, referring to fig. 4 and 5, the rotating plate 111 is opened with a first mounting hole 1111 for receiving and fixing an end of the first torsion spring 121 and a second mounting hole 1112 for receiving and fixing an end of the second torsion spring 122. The first and second torsion springs 121 and 122 can be fixedly connected to the rotating disk 111 through the first and second mounting holes 1111 and 1112, and the springs can be protected by the mounting holes.

In the present disclosure, referring to fig. 2 and 3, the locking member 2 may be configured as a U-shaped plate having an upward opening, the opening of the U-shaped plate is formed as the above-mentioned channel for the swing link 11 to swing, and the bottom of the U-shaped plate is formed as the second limiting portion. The channel is used for preventing the swing rod 11 from falling off laterally, the position of the downward movement of the swing rod 11 is limited by the bottom of the U-shaped plate, and when the swing rod 11 is fastened at the bottom of the U-shaped plate, the container locking mechanism is kept at the locking position.

The present disclosure does not limit the specific configuration of the swing link 11. According to one embodiment, referring to fig. 3, the free end of the lever body 112 may be formed with an inflection portion 113, and in the locking position, the inflection portion 113 stops the U-shaped plate. In the locked state, the rod body 112 passes through the opening of the U-shaped plate, and the inflection part 113 is buckled on the outer side surface of the bottom of the U-shaped plate. With this arrangement, referring to fig. 2, in the locked position, the lock member 2 can restrict the rotation of the second apron 4, and the inflection portion 113 of the moving member can restrict the rotation of the first apron 3, that is, in this case, neither the first apron 3 nor the second apron 4 can rotate. The inflections 113 may be configured as L-shaped corners as shown in the drawing, or may be formed as a disk or the like having a diameter larger than the opening of the U-shaped plate as long as they can be stopped at the side of the U-shaped plate.

Further, referring to fig. 2, the second enclosing plate 4 may be provided with a long hole 41 extending vertically, the swing link 11 passes through the long hole 41 from the inside of the second enclosing plate 4 and extends to the locking member 2, and an upper end inner wall of the long hole 41 forms a first limiting portion. The vertically extending elongated hole 41 formed in the side surface of the second enclosing plate 4 can also limit the vertical rotation of the swing link 11, wherein the first limiting portion is used for limiting the limit of the upward movement of the swing link 11. The lower end inner wall of the elongated hole 41 can be set to be lower than the bottom height of the U-shaped plate, so that the bottom of the opening of the U-shaped plate can be ensured to be a second limiting part, and the situation that the swing rod 11 cannot swing downwards due to the fact that the swing rod reaches the lower end inner wall of the elongated hole 41 when the swing rod 11 does not completely enter the opening of the U-shaped plate is avoided, so that the risk that the swing rod 11 breaks away from the opening of the U-shaped plate is avoided.

In addition, the present disclosure also provides a vehicle, which includes a cargo box, wherein the cargo box includes the cargo box locking mechanism, and the vehicle has all the advantages of the cargo box locking mechanism, and the detailed description is omitted here.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, various possible combinations will not be separately described in this disclosure.

In addition, any combination of various embodiments of the present disclosure may be made, and the same should be considered as the disclosure of the present disclosure, as long as it does not depart from the spirit of the present disclosure.
