Description

Technical Field

[0001] This invention relates to the field of locking technology for roof box loading, and more particularly to cargo loading devices. Background Technology

[0002] For various locking mechanisms, most implement simultaneous locking and unlocking of multiple lock blocks. In the unlocking or locking control, as soon as it is touched, it immediately triggers the unlocking or locking process. Although this improves the overall locking efficiency, it has security risks, allowing others to quickly unlock the lock mechanism. Furthermore, if the linkage during unlocking is always in the same direction, it is also easy to crack the unlocking process. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a cargo carrying device that, by increasing the number of touch points, requires a certain distance of movement before unlocking, and then unlocks from another direction, thus achieving high safety performance.

[0004] To solve the above-mentioned technical problems, the present invention provides a cargo carrying device, the technical solution of which is as follows: A cargo carrying device includes a container and a lid that constitute a cargo carrier, and a locking mechanism arranged on the container and lid. The locking mechanism includes a fixed locking element and a movable locking element, one of which is disposed on the container and the other on the lid. It also includes an actuating mechanism that causes the movable locking element to move from a locked position to an unlocked position. The movable locking element includes a linkage member that is linked to the actuating mechanism. When the linkage member moves to the actuated position in a first direction, it triggers a driving mechanism to move in a second direction, causing the movable locking element to move from the locked state to the unlocked state until unlocking is completed.

[0005] Furthermore, the movable lock element also includes a foolproof component to assist in the locking action. When the fixed lock element is driven by force to move the pressure rod, the pressure rod drives the movable lock element to lock at the same time, and the foolproof component is acted simultaneously to press the foolproof component to the set pressing position.

[0006] Furthermore, the linkage is provided with a clamping groove. When the linkage moves along the first direction to the decompression position, the clamping groove and the anti-fooling component change from the clamping position to the misaligned position, and the clamped anti-fooling component resets and moves along the second direction.

[0007] Furthermore, the clamping groove and the triggering position are misaligned. During the unlocking of the linkage, the linkage first contacts the triggering position and then contacts the decompression point.

[0008] Furthermore, it also includes an assembly housing, wherein the anti-foolproof component is assembled inside the assembly housing via a return spring, and after decompression, it extends out of the assembly housing through the decompression port.

[0009] Furthermore, the movable lock element includes a first lock hook and a second lock hook, both equipped with torsion springs. Under the combined action of the pressure rod and the torsion spring, the two move closer together to form a locking path with a locking cavity. Under the action of the drive mechanism and the torsion spring, the two move away from each other to form an unlocking path where the locking cavity splits.

[0010] Furthermore, during the locking of the fixed locking element, the pressure rod is forced to move the locking hook one toward the locking position of the locking hook two which is rotatably connected to the driving mechanism, so that the pressure rod is in the locking cavity formed by the locking hook one and the locking hook two.

[0011] Furthermore, both the first and second locking hooks are equipped with hooks. When locked, the end of the second locking hook is locked inside the hook of the first locking hook.

[0012] Furthermore, a guide surface is formed below the linkage component along the second direction, and a fitting inclined surface matching the linkage component is formed on the lower surface of the drive mechanism.

[0013] Furthermore, the actuation mechanism includes a connecting rod that is linked with the linkage member. The connecting rod has a free stroke section. After the connecting rod moves at least one free stroke section, it contacts the linkage member and drives it to move.

[0014] The present invention has the following beneficial effects: In this invention, a trigger position is set, and during unlocking, the device first slides through a neutral position and then initiates the unlocking process from another direction via a drive mechanism. This increases the unlocking distance and makes the unlocking process relatively more complex, thereby improving security. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0019] See attached document Figure 3-10 As shown, the cargo carrying device in this embodiment includes a box 60 and a box cover 70 that constitute the cargo carrying device, and a locking mechanism arranged on the box 60 and the box cover 70. The locking mechanism includes a fixed locking element 30 and a movable locking element 20. One of the fixed locking element 30 and the movable locking element 20 is arranged on the box 60 and the other is arranged on the box cover 70. When either one is touched, the movable locking element 20 will move closer to the fixed locking element to achieve the relevant function.

[0020] In this embodiment, one or more locking mechanisms can be provided between the box body 60 and the box cover 70, and an unlocking mechanism 10 can be provided between the box body 60 and the box cover 70. During unlocking, touching the unlocking mechanism 10 can unlock one or more locking mechanisms.

[0021] As an improvement, this embodiment also includes an actuating mechanism 40 linked to the unlocking mechanism 10. The actuating mechanism 40 causes the movable lock element 20 to move, completing the process of moving from the locked position to the unlocked position. In this embodiment, the movable lock element 20 includes a linkage member 23 linked to the actuating mechanism 40. When the linkage member 23 moves to the touch position along the first direction, it triggers the driving mechanism 25 to move along the second direction, driving the movable lock element 20 from the locked state to the unlocked state until unlocking is completed. In the unlocking process of this embodiment, there is an empty stroke before the formal unlocking is initiated, thus improving the overall security. At the same time, during the empty stroke, the actuating mechanism and the unlocking mechanism are linked in the same direction, but the driving mechanism has not yet been driven to unlock, thereby prolonging the time for thieves or other malicious unlocking attempts and improving security. For example, in outdoor or poorly lit locations, if someone tries to unlock the roof box, the load-bearing mechanism in this embodiment provides relatively high security.

[0022] To further enhance safety, a foolproof element 24, which also assists in the locking action, is provided on the movable locking element 20. When the fixed locking element 30 is under force and drives the pressure rod 31 to move, the pressure rod 31 simultaneously locks the movable locking element 20 and applies force to the foolproof element 24, pressing it from the outside to the set pressing position. During the locking process, to prevent fooling and ensure locking safety, the foolproof element 24 is added. The connecting rod 31 acts synchronously on the foolproof element 24, eliminating the need for a separate structure and simplifying the entire operation.

[0023] In the foolproof control, a clamping groove 232 is first provided on the linkage 23. When the linkage 23 moves to the decompression position along the first direction, the clamping groove 232 and the foolproof component 24 change from the clamping position to the misaligned position, and the clamped foolproof component 24 resets and moves along the second direction. The addition of the clamping groove 232 makes the design in this embodiment more ingenious than simple mechanical collision-based foolproofing. In particular, the clamping groove 232 effectively limits the movement of the foolproof component 24, preventing it from shifting after locking. In this embodiment, the foolproof component 24 is initially at the clamping groove 232. When the foolproof component 24 is moved, it disengages from the clamping groove 232. Previously, the foolproof component 24 was clamped in the height direction by the clamping groove 232. After moving, the foolproof component 24 is no longer clamped in the horizontal direction, and thus bounces upwards, moving in the height direction. At this point, it is not on the same horizontal plane as the clamping groove 232, achieving misalignment.

[0024] Throughout the unlocking process, the clamping groove 232 and the trigger position are misaligned. During unlocking, the linkage 23 first contacts the trigger position and then contacts the decompression point. There is a certain sequence at this time. The unlocking must be triggered first and held for a certain distance before the foolproof mechanism can be activated, thereby reducing unnecessary problems caused by misoperation. At the same time, this sequence also ensures the foolproof effect. Otherwise, if the foolproof mechanism resets before the unlocking is reached, the foolproof effect will be poor.

[0025] Specifically, for the assembly of the reset component, etc., it also includes an assembly housing 26. The foolproof component 24 is assembled inside the assembly housing 26 by a reset spring, and after decompression, it extends out of the assembly housing 26 through the decompression port. Furthermore, in the locked state, the foolproof component 24 is pressed into the assembly housing 26 by the clamping groove 232, and when unlocked, it extends out of the assembly housing 26, which has a prompting effect.

[0026] In this embodiment, the structure in the movable locking element 20 completes the locking process. Specifically, it is equipped with two locking hooks, 21 and 22, each with a torsion spring. Under the combined action of the pressure rod 31 and the torsion spring, the two hooks move closer together to form a locking path with a locking cavity. Under the action of the drive mechanism 25 and the torsion spring, the two hooks move away to form an unlocking path where the locking cavity splits. Thus, the actual locking and unlocking are achieved by the two hooks moving closer together and engaging or moving away from each other to disengage.

[0027] Referring to the accompanying drawings, during the locking of the fixed locking element 30, the pressure rod 32 is forced to move the locking hook 21 toward the locking position of the locking hook 22, which is rotatably connected to the driving mechanism 25, so that the pressure rod 31 is placed within the locking cavity formed by the locking hook 21 and the locking hook 22. Furthermore, in this embodiment, although locking is performed on both locking hooks 1 and 2, the pressure rod in the fixed locking element is also locked and limited to ensure a secure lock.

[0028] For the specific structure, both locking hook 21 and locking hook 22 are equipped with hooks. When locked, the end of locking hook 22 is locked into the hook of locking hook 21. At this time, the locking hooks abut against each other and lock together, cleverly utilizing the arc shape of the hooks, which is an ingenious design.

[0029] The reason for the initial activation of the drive mechanism is that a guide surface is formed below the linkage 23 along the second direction, and the lower surface of the drive mechanism 25 forms a matching inclined surface that mates with the linkage 23. When the linkage starts to move, the two guide inclined surfaces are not in contact; they only come into contact and trigger at the set point position, at which point the activation position is reached.

[0030] In this embodiment, to form the previous idle stroke, the actuation mechanism 40 includes a connecting rod 41 that is linked with the drive linkage 23. The connecting rod 41 has an idle stroke section. After the connecting rod 41 moves at least one idle stroke section, it contacts the linkage 23 and drives it to move. In this embodiment, specifically, a cavity structure 42 is formed to create the idle stroke section.

[0031] In this embodiment, the unlocking unit 10 can be diverse, such as fingerprint module recognition unlocking or mechanical key unlocking. After fingerprint module recognition unlocking or mechanical key unlocking, it is linked to unlock two or more locking mechanisms 80. During assembly, two or more locking mechanisms 80 are partially assembled on the housing 60 and partially assembled in the lid 70. This part can be located inside the housing and lid, or simultaneously on the outside. It can be mostly located on the lid, mostly on the housing, or evenly distributed, all without affecting the overall design.

[0032] See attached document Figure 1 As shown, the unlocking process in this embodiment is as follows: The unlocking unit 10 initiates the unlocking action, and an external force is applied to the unlocking component 11, which starts the actuation mechanism to move along the first direction 40; When the actuating mechanism 40 completes its idle stroke and moves to the activated position, it contacts the linkage 23 to unlock the movable lock element 20. When the movable lock element 20 starts to move in the first direction or moves to a set position, the linkage 23 passes through the guide surface to make the drive mechanism 25 move upward in the second direction, and the lock hook 1 21 begins to disengage from the lock hook 2. The linkage 25 continues to move into the misaligned position, and the anti-fooling component 24 is decompressed, released, and pops out. The movable lock element 20 continues to move until the first lock hook 21 and the second lock hook 22 are unlocked.

[0033] See attached document Figure 2 As shown, the locking process in this embodiment is as follows: An external force is applied to the connecting rod 31 in the fixed locking element 20, causing it to act synchronously on the lock hook 21 and the anti-fooling component 24 and move toward the assembly housing 26. During the movement of the locking hook 21, the drive mechanism 25, which is rotatably connected to it, moves in the second direction, and the drive mechanism 25 drives the linkage 23 to move in the first direction in the opposite direction to the direction of the unlocking process. The linkage 23 also first moves in the idle stroke segment before contacting the linkage 41, driving the unlocking part 11 to reset and complete the locking.

[0034] During the locking process described above, when multiple locking mechanisms are present, due to the existence of the idle travel segment, some of the locking hooks 1 and 2 have already completed locking during the movement in the idle travel segment, thus achieving the effect of single-point locking.

[0035] In the above locking process, when the linkage 23 returns to the set position, the anti-fooling component 24 aligns with the clamping groove, which just completes the clamping and achieves the locking fixation.

[0036] Compared to existing locking controls, the key feature of this embodiment is that when two or more locking mechanisms 80 are locked, and at least one locking mechanism 80 is in the locked state, an external force is applied to the unlocked locking mechanism 80, causing all locking mechanisms 80 to lock, the latch system to engage, and the unlocking unit 1 to reset. Specifically, for example, if there are two locking mechanisms 80, and only one is locked, the other unlocked locking mechanism 80 can be locked by applying an external force to the box or lid. This solves the problem in existing technologies where some parts are not fully locked, affecting usability, especially when applied to roof boxes, where items are not properly organized, causing partial latching units to fail to lock. The method in this embodiment effectively solves this problem.

[0037] The following section will introduce the specific structure and control process.

[0038] First, regarding the locking mechanism, the following is an introduction: See attached document Figure 1-8 As shown, the locking mechanism 80 specifically includes a movable locking element 20 fixed to the box body 60 and a fixed locking element 30 fixed to the box cover 70. During operation, by pressing down on the box cover 70 to bring it close to the box body 60, the fixed locking element 30 locks with the movable locking element 20, and the unlocking element 11 in the unlocking mechanism 10 resets. In this embodiment, when unlocking is required, the unlocking element 11 is also activated, causing it to move to a specific position, thereby unlocking (details will be explained later).

[0039] In this embodiment, multiple locking mechanisms 80 are provided in the locking of the roof box. When locked, the lid 70 is pressed down, and the fixed locking element 30 and the movable locking element 20 are close together. Normally, it is in a locked state. However, sometimes the contents of the box may obstruct the lid from closing, resulting in an obstruction that causes some locking units to be in a false lock state. At this time, the unlocking element 11 is still in a compressed state and cannot be reset. This can remind the user that it is not fully locked and needs to be checked and relocked.

[0040] Secondly, the locking unit and locking mechanism are described below: See attached document Figure 9 and 10It can be seen that the unlocking mechanism 10 includes an unlocking component 11 connected to synchronous locking or unlocking. The unlocking component moves along the unlocking shell located on the cover 70 or the body 80 to unlock or reset.

[0041] To facilitate alerting users to a false lock or incomplete lock, this embodiment also includes a warning strip 12 located inside the unlocking housing. In the false lock state, the warning strip 12 is exposed. Of course, in the incomplete lock state, the unlocking component 11, which is moved during unlocking, cannot return to its original position, and in this case, the warning strip 12 is also exposed.

[0042] See attached document Figure 3 and 7 As described above, the movable lock element 20 includes a first lock hook 21, a second lock hook 22, a linkage 23, a foolproof component 24, and a drive mechanism 25. The drive mechanism 25 is rotatably connected to the second lock hook 22. The drive mechanism 25 has an oblong hole, forming a cavity mechanism. During horizontal movement of the drive mechanism 25, the second lock hook 22 will rotate to a certain extent. The linkage 232 has a guide surface 231 along the vertical direction, and a pressing groove 232 is provided in a direction offset from the guide surface 231. When the linkage 23 slides to a set position, it contacts the drive mechanism 25, and the guide surface 231... The guiding mechanism 25 moves upward or downward. Both the first and second locking hooks are equipped with torsion springs. At this time, the second locking hook 22 rotates, unlocking or locking with the first locking hook 21. The anti-fooling component 24 is spring-loaded into the assembly housing 26 of the movable locking element 20. As the driving mechanism moves upward, it disengages from the first locking hook of the driving mechanism, thus unlocking. During this process, as the linkage slides, the pressing groove 232, which was originally far away from the anti-fooling component, moves closer to the anti-fooling component 24 and is exposed. As the linkage moves, the previously pressed anti-fooling component 24 resets, moves upward, and is exposed.

[0043] When the moving mechanism 25 moves downward under the force, the second locking hook 22, under the action of the moving mechanism 25 and the torsion spring, resets and rotates upward, approaches the first locking hook 21, and locks with the moving first locking hook 21.

[0044] The fixed locking element 30 includes a pressure rod 31. In actual use, the pressure rod 31 directly acts on the first locking hook 21 and the anti-fooling component 24, causing them to move downwards. During this process, the anti-fooling component 24 is also forced to press down and move downwards. At this time, when the first locking hook 21 contacts the second locking hook 22, the second locking hook 22 begins to rotate, driving the drive mechanism 25 to move downwards and contact the guide surface 231, causing the linkage to move horizontally and achieve locking. As for the anti-fooling component 24, it extends horizontally to form a locking part 241. During unlocking, the locking part 241 and the entire anti-fooling component 24 move upwards and are exposed under the action of the bottom return spring. During locking, if it is not locked in place, although the locking part 241 will move downwards under the downward pressure, it cannot be well matched with the pressing groove 232. Therefore, the pressure rod 31 needs to be pressed down to complete the match between the two to achieve complete locking and avoid false locking.

[0045] Next, we will introduce synchronous locking or tightening.

[0046] See attached document Figure 9-10 As shown, the synchronous locking or unlocking unit includes the unlocking mechanism 10 fixed on the housing 60 and the connecting rod 41 linked with the unlocking mechanism 10. At this time, the movable locking element 20 is embedded in the connecting rod 41. The unlocking mechanism 10 drives the connecting rod 41 to push, synchronously controlling the unlocking of the locking mechanism 10. In actual use, the unlocking mechanism 10 is connected to the connecting rod 41, and then the synchronous control of unlocking is achieved by controlling the movable locking element 20. Specifically, the unlocking element 11 moves horizontally, causing the connecting rod 41 to also move horizontally left and right (in this embodiment, it moves to the right to achieve unlocking). Then, several linkage elements 23 fixed to the connecting rod 4 drive the drive element 25 to move upward, causing the second locking hook 22 to rotate. The locking hook 21, which was pressed down on the locking hook 22, is released, completing the entire unlocking process. At the same time, the anti-fooling element 24 is reset and extended during this process, providing a basis for subsequent judgment of whether the locking is in place and whether there is a false lock. If the false lock anti-fooling key 2-4 is not completely reset, it indicates that the locking is not complete and there is a false lock.

[0047] In this embodiment, the linkage 23 is assembled on the pull rod 41. The pull rod 41 has a 10-15mm cavity groove forming the cavity structure. During the unlocking process, when the pull rod 41 moves horizontally, the linkage 23 does not move initially. Only after the pull rod 41 has completed the entire stroke of the cavity does the linkage 23 and the pull rod 41 begin to move horizontally in tandem. In this embodiment, the purpose of this cavity groove is that when multiple locking mechanisms 80 are in operation, if one or more locking units are locked, the locking mechanism only translates the movement of this cavity groove without driving the entire connecting rod 41 to move, thus achieving a partially or single-point locking state, but not a fully locked state. At this time, by pressing or other actions, other locking mechanisms can be driven to complete the locking, causing the connecting rod 41 to drive the unlocking component 11 to reset and complete the locking. This operation method is simple and easy to implement. Specifically, in this embodiment, the cavity groove can be an oblong hole.

[0048] Finally, the usage process of this invention will be described.

[0049] See attached document Figure 3 and 7 As shown in this embodiment, when the locking hook 21 and locking hook 22 are locked, a mounting hole is formed. At this time, the pressure rod 31 on the fixing locking element 30 is completely locked in the mounting hole. In this embodiment, during locking, the pressure bar 31 on the locking mechanism 80 acts simultaneously on the first locking hook 21 and the anti-fooling component 24 by pressing down the box cover 200, causing them to move downwards. The first locking hook 21 contacts the second locking hook 22 during its downward rotation. Combined with the action of the torsion spring, the second locking hook 22 rotates. The drive mechanism 25, which is rotatably connected to it through the waist hole, has its side connected to the assembly shell of the movable locking element 20 through a spring. Previously, when unlocking, the drive mechanism 25 moved, causing the spring to be pulled out. At this time, the spring's restoring force and the linkage of the second locking hook 22 cause it to move downwards, causing the inclined surface at its bottom to contact the guide surface, driving the linkage component to move horizontally (at this time, the direction of movement is opposite to that during locking). During the pressing down of the pressure bar, before reaching the fully locked position, the locking part 241 in the anti-fooling component 24 will not be completely locked with the pressing groove, and the spring at its bottom will not be completely compressed. Therefore, the anti-fooling component 24 still has a certain downward pressing space, which can determine whether it is in a false locking state.

[0050] In this embodiment, during the locking process, both locking hook 21 and locking hook 22 are arc-shaped, or both are semi-circular. Therefore, when fully locked, alignment can form the assembly hole, at which point the pressure rod 31 can contact and press down on the anti-fooling component 24. When not fully locked, locking hook 21 or the linkage keeps the entire movement between the first and second positions, forming a false lock state.

[0051] During assembly, the fixed locking element 20 and the pressure rod 31 are located in the box cover. When they are pressed down, they can just contact the movable locking element 30 to complete the locking.

[0052] In this embodiment, when locking, if part of the lock is locked and part of the lock is in a false lock state, due to the presence of the cavity groove on the connecting rod 41, when the linkage moves in the opposite direction, it will first move along the cavity groove. At this time, the unlocked locking unit will also first move along the cavity groove. During this process, the connecting rod 41 does not move, that is, the unlocking member 11 does not reset, and the warning strip 12 is exposed. Thus, this usage process and state ensures single-point or partial locking, but does not affect the overall locking.

[0053] In this embodiment, when there is a false lock or the lock is not fully locked, the linkage 41 cannot drive the unlocking component 11 back to its original position. In order to improve the user experience, a warning strip 12 is formed in the sliding trajectory of the unlocking component 11 by coloring or other means. As long as it does not return to its original position, the warning strip 12 will form a prompt signal to remind the user that the roof box is not fully locked.

[0054] In this embodiment, the fixed locking element 20 cleverly utilizes the setting of inclined surfaces and grooves to enable the linkage component, the anti-foolproof component, and the drive mechanism to form a linkage, thereby realizing the control of other structures during its movement.

[0055] In this embodiment, a pressure cap 50 is provided on the outside of the connecting rod 41 to form a limiting groove, thereby giving the connecting rod 41 a certain protective cavity.

[0056] The locking system in this embodiment is used in the roof box. Since the roof box is not easy to access, its security is particularly important. This embodiment avoids problems such as difficulty in pressing down and difficulty in use by using warning strips and various linkages, especially the ability to lock each locking point individually.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
