[0003] 1. The safety of the main structure is insufficient, and there may be a situation where the locking point is not locked, and thus there is a false locking situation;
[0004] 2. The product function is single, and manual locking is required;
[0005] 3. The locking operation of the product is cumbersome, and it can only be locked when all the locking points are aligned;
[0006] 4. The structural stability is poor, and the structural reliability is weak. It can only be locked when each locking point is aligned, otherwise it cannot be locked;
[0007] 5. The structural stability is poor. Summary of the Utility Model
[0008] The technical problem to be solved by the utility model is to provide a lock system, so that when some of the locking points are not aligned among multiple locking units, the locking can still be completed.
[0009] In order to solve the above technical problems, the technical solution provided by the utility model is as follows:
[0010] A lock system is used for locking and closing or unlocking and opening a box body and a box cover. The lock system includes at least two locking units connected by a synchronous locking or unlocking unit. Driving the synchronous locking or unlocking unit to act drives the unlocking unit to synchronously unlock the two locking units;
[0011] When at least one of the two locking units is in a locked state, an external force acts on the unlocking unit in the unlocking state, so that all the locking units are locked, the lock system is locked, and the unlocking unit is reset.
[0012] Further, the locking unit includes a locking body fixed on the box body and a locking mechanism fixed on the box cover. Press down the box cover to make it close to the box body, and the locking mechanism is locked with the locking body, and the reset component in the unlocking unit acts to reset the unlocking unit.
[0013] Further, during the pressing down of the box cover, the locking mechanism acts on the locking body, so that the locking body is in a locked state or a false locked state, and when in the false locked state, the reset component is in a compressed state.
[0014] Furthermore, the unlocking unit comprises a sliding unlocking member connected to the synchronous locking or unlocking unit, and the sliding unlocking key moves along an unlocking shell located on the box cover or the box body to unlock or reset.
[0015] Furthermore, it also includes a warning strip located in the unlocking shell, and in the false lock state, the warning strip is in an exposed state.
[0016] Furthermore, a contact key is formed on the lock body, and when the box cover is pressed down, the locking mechanism drives the contact key to move within a trajectory formed by the first position and the second position to determine the working state of the locking unit.
[0017] Further, when in the fully unlocked state, the locking unit is in the first position, and when in the fully locked state, the locking unit is in the second position, otherwise the locking unit is in a false locked state.
[0018] Furthermore, the synchronous locking or unlocking unit is provided with a space for accommodating the locking mechanism.
[0019] Furthermore, the synchronous locking or unlocking unit includes the unlocking unit fixed on the box body and a connecting rod linked to the unlocking unit, the locking unit is embedded in the connecting rod, and the unlocking unit drives the connecting rod to push and synchronously control the unlocking of the locking unit.
[0020] Furthermore, it also includes a sliding cover located on the box body and forming a limiting groove, and the connecting rod moves back and forth along a set trajectory inside the sliding cover.
[0021] Furthermore, the locking mechanism is linked with the synchronous locking or unlocking unit, and the locking mechanism forms a driving mechanism to push the lock hook 1 and the lock hook 2 in the lock body to complete locking or unlocking.
[0022] Furthermore, when the box cover is pressed down, the locking mechanism also includes a locking rod located on the box cover. When the locking rod is pressed down by force, the first locking hook is pressed down to complete locking with the second locking hook.
[0023] Furthermore, when the box cover is pressed down, the lock hook body also includes a conversion member linked to the locking mechanism, and the lock hook is assembled on the conversion member.
[0024] The utility model has the following beneficial effects:
[0025] 1. It can be unlocked and locked quickly and easily. When the upper cover is closed, the lock hook is automatically locked. When it needs to be unlocked, pull the switch, the upper cover is automatically unlocked and stops in the unlocked state.
[0026] 2. Safety: In order to ensure that each lock point locks the upper cover, a false lock anti-fool mechanism is set. If one or more lock points are not locked, the reset switch cannot be reset and a reminder will be given.
[0027] 3. The common locking mechanism on the market requires all the locking points to be aligned and locked when the upper cover is closed before manual locking. When there is something blocking somewhere inside the box, all the locking points cannot be locked. It is difficult to operate when one person is leaning against it. This structure has the function of automatic locking when a single locking point is locked. When encountering such a situation, you only need to press down at a certain place to achieve locking.
[0028] 4. Strong structural stability, by simplifying parts and using one part for multiple functions, the number of parts is reduced, assembly is reduced, and structural stability is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present utility model will be described in detail below with reference to the embodiments shown in the drawings. It should be noted that these embodiments are not limitations on the present utility model, and any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art according to these embodiments shall fall within the protection scope of the present utility model.
[0045] Referring to the attached Figures 1-12 As shown, the lock system in the present utility model is used for locking and closing or unlocking and opening the box body 100 and the box cover 200. The lock system includes at least two lock units 300 connected by a synchronous locking or unlocking unit 400. Driving the synchronous locking or unlocking unit 400 to act drives the unlocking unit 1 to synchronously unlock the two lock units 300. In this embodiment, the unlocking unit 1 can be diversified, 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 lock units 300. During assembly, two or more lock units 300, a part of which is assembled on the box body 100 and a part is assembled in the box cover 200. Here, it can be set on the inner side of the box body and the box cover, or can be set on the outer side at the same time. Then, it can be mostly located on the box cover, or mostly located on the box body, or evenly distributed, which has no influence.
[0046] Compared with the locking control in the prior art, the prominent feature in this embodiment is that when two or more of the latch units 300 are locked and at least one of the latch units 300 is in the locked state, by applying an external force to the latch unit 300 in the unlocked state, all the latch units are locked, the latch system is locked, and the unlocking unit 1 is reset. Specifically, for example, if there are two latch units 300 and only one is locked, then the other unlached latch unit 300 can be locked by applying an external force to the box body or the box cover, thus solving the situation in the prior art where partial non-locking leads to incomplete locking and affects the use. Especially when applied to a roof luggage rack, when the items are not properly arranged, etc., the local pressure on some latch units prevents them from being locked, and the method in this embodiment solves this problem well.
[0047] The following is an introduction to the specific structure and control process, etc.
[0048] First, regarding the latch unit, the introduction is as follows:
[0049] Referring to the appendix Figures 1-8 As shown, the latch unit 300 specifically includes a latch body 2 fixed to the box body 100 and a locking mechanism 3 fixed to the box cover 200. During operation, by pressing down the box cover 200 to make it close to the box body 100, the locking mechanism 3 is locked with the latch body 2, and the reset component 1-1 in the unlocking unit 1 acts to reset the unlocking unit 1. In this embodiment, when unlocking is required, it is also by acting on the reset component 1-1 to move it to a specific position to drive the unlocking (specifically described later).
[0050] In this embodiment, in the locking of the roof luggage rack, multiple latch units 300 are provided. When locking, the box cover 200 is pressed down, and the locking mechanism 3 approaches the latch body 2. Usually, it will be in the locked state. However, sometimes due to the obstruction of the items inside the box preventing the upper cover from closing, there is an obstruction, making some latch units in a false locked state. At this time, the reset component 1-1 is still in the compressed state and cannot be reset, thus being able to remind the user in time that it is not fully locked and needs to be checked and re-locked.
[0051] Secondly, the introduction to the locking unit and the locking mechanism is as follows:
[0052] Referring to the appendix Figure 9 and 10 It can be seen that the unlocking unit 1 includes a sliding unlocking member 1-3 connected to the synchronous locking or unlocking unit 400. The sliding unlocking key 1-3 moves along the unlocking shell located on the box cover 200 or the box body 100 for unlocking or resetting. In this embodiment, the reset component 1-1 and the sliding unlocking member 1-3 are of the same structure for easy control.
[0053] To facilitate reminding the user of the existence of a false lock or incomplete locking, a warning strip 1-2 located inside the unlocking shell is further included in this embodiment. In the false lock state, the warning strip 1-2 is in an exposed state. Of course, in the state of incomplete locking, when unlocking, the reset component 1-1 that has been driven to move cannot be reset, and at this time, the warning strip 1-2 is also exposed.
[0054] Refer to the appendix Figure 3 and 7 As described etc., the buckle body includes a first locking hook 2-1, a second locking hook 2-2, a contact key 2-3, a false lock anti-fooling key 2-4, and a card seat sliding member 2-5. The card seat sliding member 205 is rotatably connected to the second locking hook 2-2. At this time, a waist-shaped hole is provided on the card seat sliding member 2-5. Thus, during the horizontal movement of the card seat sliding member 205, the second locking hook 2-2 will be driven to rotate to a certain extent; a guiding inclined surface 2-3-1 is provided on the conversion member 2-3 in the vertical direction, and an avoidance groove 2-3-2 is provided in the direction misaligned with the guiding inclined surface 2-3-1. When the conversion member 2-3 slides to a set position, it contacts the card seat sliding member 2-5, and the guiding inclined surface 2-3-1 guides the card seat sliding member 2-5 to move upward or downward. Torsion springs are provided on both the first locking hook and the second locking hook. At this time, the second locking hook 2-2 is driven to rotate, and unlocks or locks with the first locking hook 2-1; the false lock anti-fooling key 2-4 is assembled in the assembly shell of the buckle body 2 through a spring. During the upward movement of the card seat sliding member 2-5, the second locking hook 2-2 linked with the card seat sliding member 2-5 is also pulled to rotate outward toward the outside of the assembly shell, and thus is disengaged from the first locking hook that is hooked and locked with it, realizing unlocking; during this process, as the conversion member slides, the avoidance groove 2-3-2 that was originally far from the false lock anti-fooling key 2-4 below the conversion member will also approach the false lock anti-fooling key 2-4 and be exposed as the conversion member moves, and then the previously pressed false lock anti-fooling key 2-4 resets and moves upward, being exposed.
[0055] When the card seat sliding member 2-5 is forced to move downward, the second locking hook 2-2 rotates upward to reset under the action of the card seat sliding member 2-5 and the torsion spring, approaches the first locking hook 2-1, and locks with the moving first locking hook 2-1.
[0056] The locking mechanism 3 includes a locking rod 3-1. In actual use, the locking rod 3-1 directly acts on the lock hook 1 2-1 and the fake lock anti-fool key 2-4 to make them move downward. During this process, the fake lock anti-fool key 2-4 will also be forced to press and move downward. At this time, when the lock hook 1 2-1 contacts the lock hook 2-2, the lock hook 2-2 starts to rotate and drives the card seat sliding member 2-5 to move downward and contact the guide inclined surface 2-3-1, so that the conversion member 2-3 moves horizontally to achieve locking. For the fake lock anti-fool key 2-4, which extends in the horizontal direction to form a locking portion 2-4-1. During unlocking, the locking portion 2-4-1 and the entire fake lock anti-fool key 2-4 move upward and are exposed under the action of the bottom return spring; while in locking, as long as it is not locked in place, the locking portion 2-4-1 will move downward under the action of downward pressure, but it cannot be well matched with the avoidance groove 2-3-2, and then the locking rod 3-1 needs to be pressed down into place, and the two need to be completely matched to complete the locking, thereby avoiding the anti-fool fake lock.
[0057] In actual use, the lock hook 2-1 and the conversion member 2-3 respectively form the contact keys for locking and unlocking. When the box cover 200 is pressed down, the locking mechanism 3 drives the contact key to move within the trajectory formed by the first position and the second position. At this time, the lock hook 1 forms an arc-shaped motion trajectory, and the conversion member 2-3 forms a horizontal motion trajectory. Then, according to the positions of the lock hook 1 and the conversion member 2-3, it can be judged whether the locking unit is in a locked or unlocked working state.
[0058] Next, the synchronous locking or locking unit 400 is introduced.
[0059] See attached Figures 9-10 As shown in the figures, the synchronous locking or unlocking unit 400 includes the unlocking unit 1 fixed on the box 100 and the connecting rod 4 linked with the unlocking unit 1. At this time, the lock body 2 is embedded in the connecting rod 4, and the unlocking unit 1 drives the connecting rod 4 to push, and synchronously controls the unlocking of the lock unit 1. In actual use, the unlocking unit 1 is connected to the connecting rod 4, and then the unlocking is synchronously controlled by controlling the lock body 2. Specifically, the sliding unlocking member 1-3 (i.e., the reset component 1-1) on the unlocking unit 1 moves horizontally, causing the connecting rod 4 to also move horizontally left and right (in the present embodiment, unlocking is achieved by moving rightward), and then a number of conversion members 2-3 fixed to the connecting rod 4 drive the card seat sliding member 2-5 to move upward, driving the lock hook 2-2 to rotate, and the lock hook 1 2-1 locked and pressed down at the lock hook of the lock hook 2-2 is released, completing the entire unlocking. At the same time, in this process, the fake lock anti-fool key 2-4 is reset and extended, which provides a basis for subsequent judgment of whether the locking is in place and whether there is a fake lock. If the fake lock anti-fool key 2-4 is not completely reset later, it means that the locking is not complete and a fake lock exists.
[0060] In this embodiment, the conversion member 2-3 is assembled on the pull rod 4. A cavity groove with a length of 10-15 mm is formed on the pull rod 4. During the unlocking process, when the pull rod 4 moves horizontally, the conversion member 2-3 does not move first. When the pull rod 4 completes the stroke movement of the entire cavity operation, the conversion member 2-3 and the pull rod 4 start to perform a horizontal linkage movement. In this embodiment, the purpose of the existence of this cavity groove is that when there are multiple locking units 300 later, if one or some of the locking units are locked, the locking unit only translates the movement of this cavity groove without driving the entire connecting rod 4 to move, thereby realizing the state where part or a single point can be locked but not completely locked. At this time, through actions such as pressing, other locking units can be driven to complete the locking, so that the connecting rod 4 drives the reset component 1-1 to reset and complete the locking. This operation method is simple and easy to implement. In this embodiment, specifically, the cavity groove can be an oval hole.
[0061] Finally, the usage process of the present utility model will be introduced.
[0062] Refer to the attached Figure 3 and 7 As shown, in this embodiment, when the first locking hook 2-1 and the second locking hook 2-2 are in the locked state, an assembly hole is formed. At this time, the locking rod 3-1 on the upper locking mechanism 3 is just completely locked in this assembly hole.
[0063] In this embodiment, when locking, by pressing down the box cover 200, the locking rod 3-1 on the locking unit 300 acts on the first locking hook 2-1 and the false lock anti-fool key 2-4 at the same time, causing them to move downward. During the downward rotation of the first locking hook 2-1, it contacts the second locking hook 2-2. With the action of the torsion spring, the second locking hook 2-2 rotates. The side part of the clamping seat sliding member 2-5 that is rotatably connected to it through an oval hole is connected to the assembly shell of the locking body 2 through a spring. During the previous unlocking, the movement of the clamping seat sliding member 2-5 caused the spring to be pulled out. At this time, driven by the spring return force and the linkage of the second locking hook 2-2, it moves downward, and then the inclined surface at its bottom contacts the guiding inclined surface 2-3-1, driving the conversion member 2-3 to perform a horizontal movement (at this time, the movement direction is opposite to that during locking); during the downward pressing process of the locking rod 3-1, before reaching the complete locking position, the clamping part 2-4-1 in the false lock anti-fool key 2-4 will not be completely assembled with the avoidance groove 2-3-2, and the spring at its bottom will not be completely compressed. Therefore, there is still a certain downward pressing space for the false lock anti-fool key 2-4, and thus it can be judged whether it is in a false lock state.
[0064] In this embodiment, during the locking process, both the first locking hook 2-1 and the second locking hook 2-2 are arc-shaped, or both are semi-circular. Thus, when fully locked, alignment can form the assembly hole, and at this time, the locking rod 3-1 can contact and press down the false-lock anti-fool key 2-4. When not fully locked, the first locking hook or the conversion member 2-3 causes the entire movement to be between the first position and the second position, forming a false-lock state.
[0065] During assembly, the upper locking mechanism 3 and the locking rod 3-1 are located in the lid 200, and when they are pressed down, they can just contact the buckle main body 2 to complete the locking.
[0066] In this embodiment, during locking, once partially locked and partially in a false-lock state, due to the existence of the cavity groove in the previous connecting rod 4, when the conversion member 2-3 moves in the reverse direction, it will first move along the cavity groove. At this time, the unlocked buckle unit will also first perform an idle stroke movement along the cavity groove. During this process, the connecting rod 4 does not move, that is, the unlocking unit 1 does not reset, and the warning strip 1-2 is in an exposed state. Thus, this usage process and state ensure single-point or partial locking, but it does not affect the overall locking.
[0067] In this embodiment, when there is a false lock or incomplete locking, the connecting rod 4 cannot drive the reset assembly 1-1 (i.e., the sliding unlocking member 1-3) back to the original position. To improve the user experience, in the sliding trajectory of the reset assembly 1-1, a warning strip 1-2 is formed by coloring or the like. As long as it does not return to the original position, the warning strip 1-2 forms a prompt signal to remind the user that the roof luggage case is not fully locked.
[0068] In this embodiment, the buckle main body 2 cleverly utilizes the settings of the inclined plane and the groove body, etc., so that the conversion member 2-3 forms a linkage with the false-lock anti-fool key 2-4 and the card seat sliding member 2-5, and controls other structures during its movement.
[0069] The buckle system in this embodiment is used in the roof luggage case. At this time, due to the inconvenience of taking the roof luggage case, etc., its safety is particularly important. And this embodiment uses a warning strip and various linkages, especially each locking point can be locked separately, avoiding problems such as difficult pressing and difficult use.
