Technical Field
[0001] This utility model relates to the field of automotive storage boxes, and in particular to a storage box locking mechanism and a storage box. Background Technology
[0002] With the increasing popularity of private cars, which have gradually become a daily means of transportation, storage boxes, as an interior feature of cars, are increasingly being demanded by users.
[0003] To prevent accidental opening, existing storage boxes are equipped with locking mechanisms. One type of locking mechanism includes a lock slot and a lock pin. The lock pin extends into the lock slot to lock, and disengages from the lock slot to unlock. A spring is usually included to allow the lock pin to automatically extend into the lock slot. However, existing lock slots and lock pins are usually made of rigid materials. Therefore, when the lock pin extends into the lock slot, it may come into contact with or collide with the wall or bottom of the lock slot, resulting in noise and affecting the quality of the storage box. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this utility model provides a storage box locking mechanism. The bottom and / or walls of the locking groove are made of soft material, and / or the end of the locking pin inserted into the locking groove is also made of soft material. Therefore, when the locking pin contacts or impacts the bottom and / or walls of the locking groove, it is quieter and avoids abnormal noises; this greatly increases the premium feel of the storage box using the locking mechanism. The utility model also provides a storage box.
[0005] To achieve the above objectives, the present invention employs the following technical solution:
[0006] A storage box locking mechanism for locking the storage box lid in a state that closes the access opening of the storage box body, comprising:
[0007] A locking structure is provided on the storage box lid, and the locking structure is provided with one of a locking pin and a locking groove;
[0008] A locking mechanism is provided on the storage box body, and the locking mechanism is provided with a locking post and a locking groove. When the storage box lid is closed and the opening of the storage box lid is closed, the locking post and the locking groove are arranged opposite to each other, and the locking post has a tendency to move towards the locking groove side, and / or the locking groove has a tendency to move towards the locking post to the locking groove side.
[0009] And an unlocking structure, which can act on the locking structure and / or the locking engagement structure to disengage the locking pin and the locking groove from each other;
[0010] The bottom and / or walls of the locking groove are made of soft material, and / or the end of the locking pin used to insert into the locking groove is made of soft material.
[0011] Using the above technical solution, when the storage box lid moves from the open / closed state to the closed state, the locking pin moves towards the locking groove and extends into it. During this process, the end of the locking pin inserted into the locking groove will contact or even collide with the groove wall and / or bottom. Because the bottom and / or wall of the locking groove are made of soft material, and / or the end of the locking pin inserted into the locking groove is made of soft material, the contact or collision between the locking pin and the bottom and / or wall of the locking groove is quieter and avoids making noise. This greatly increases the premium feel of the storage box using the locking mechanism.
[0012] Furthermore, the locking structure is provided with the locking post, and the locking mating structure is provided with the locking groove.
[0013] The above technical solution makes the storage box locking mechanism more reasonable.
[0014] Furthermore, the bottom and walls of the locking groove are made of soft material, while the locking pin is made of hard material.
[0015] By adopting the above technical solution, the setting of the locking groove is more reasonable. Since the locking pin may come into contact with or collide with the bottom of the locking groove or with the wall of the locking groove during the process of the locking pin being inserted into the locking groove, the bottom and wall of the locking groove are made of soft materials, which can greatly improve the noise reduction effect and avoid abnormal noise.
[0016] The locking pin is made of a rigid material, which ensures a stable and reliable locking fit when it is inserted into the locking groove.
[0017] Furthermore, in the locking structure and the locking mating structure, one of the components having the locking groove is made of a soft material, or in the locking structure and the locking mating structure, one component having the locking groove includes a locking groove mounting bracket and a locking groove structure disposed on the locking groove mounting bracket, wherein the locking groove is disposed on the locking groove structure, the locking groove structure is made of a soft material, and the locking groove mounting bracket is made of a rigid material.
[0018] By adopting the above technical solution, the structure in which the locking structure and the locking mating structure are provided with the locking groove is more reasonable; preferably, the locking structure and the locking mating structure in which the locking groove is provided include the locking groove mounting bracket and the locking groove structure, which facilitates the formation of the soft locking groove, and the rigid locking groove mounting bracket can support the locking groove structure, ensuring the stability and reliability of the structure.
[0019] Furthermore, the locking slot mounting bracket has a locking slot mounting slot for mounting the locking slot structure, and the locking slot structure is mounted in the locking slot mounting slot.

[0021] Furthermore, the locking slot mounting bracket and the locking slot structure are formed into a single piece using a multi-color injection molding process. Specifically, the locking slot mounting bracket and the locking slot structure are formed into a single piece using a two-color injection molding process.
[0022] By adopting the above technical solution, the connection between the locking groove mounting bracket and the locking groove structure can be made more stable and reliable due to the use of multi-color injection molding process. Furthermore, the locking groove mounting bracket and the locking groove structure can be made of different materials, with the locking groove mounting bracket made of rigid material and the locking groove structure made of soft material.
[0023] Furthermore, along the direction from the opening of the locking groove to the bottom of the groove, the groove wall of the locking groove gradually slopes towards its central axis.
[0024] By adopting the above technical solution, the groove wall of the locking groove can guide the insertion of the locking pin, making it easier for the locking pin to be inserted into the locking groove.
[0025] Furthermore, when the storage box lid is closed and the opening of the storage box lid is closed, the locking structure tends to move toward the locking engagement structure, and the locking pin and the locking groove tend to move closer to each other for insertion and engagement.

[0043] By adopting the above technical solution, the setting of the connecting pin can play a certain guiding and restricting role in the sliding of the locking structure; at the same time, since the locking structure reset component is sleeved on the connecting pin, the locking structure reset component can be prevented from twisting, etc., so that the locking structure reset component can work more stably and reliably.
[0044] Furthermore, the unlocking structure includes an unlocking drive reset member, which acts on the unlocking drive member to cause it to have a tendency to slide towards the head side of the storage box lid after sliding towards the tail side of the storage box lid.
[0045] By adopting the above technical solution, the unlocking drive reset component is configured so that the unlocking drive component can automatically reset after the user removes the force applied to it.
[0046] Furthermore, the unlocking structure includes a drive component mounting base disposed on the storage box cover, wherein the unlocking drive component is slidably disposed on the drive component mounting base along the length direction of the storage box cover.
[0047] By adopting the above technical solution, the unlocking structure becomes more reasonable, and the driving component mounting base provides an installation foundation for installing the unlocking driving component.
[0048] Furthermore, the unlocking drive component is provided with sliding mating strips on both sides, and the sliding mating strips extend along the length direction of the storage box cover. Correspondingly, the mounting base is provided with sliding mating grooves on both sides of the unlocking drive component that match the sliding mating strips.
[0049] By adopting the above technical solution, the cooperation between the sliding mating strip and the sliding mating groove can guide the sliding of the unlocking drive component and restrict the movement of the unlocking drive component in other directions, so that the unlocking drive component can be stably and reliably installed on the drive component mounting base.
[0050] Furthermore, the driving component mounting base is provided with a first reset component abutment surface, and the unlocking driving component is provided with a second reset component abutment surface. The first reset component abutment surface and the second reset component abutment surface are arranged opposite to each other, and the second reset component abutment surface is arranged closer to the head of the storage box cover than the first reset component abutment surface. The unlocking driving reset component is arranged between the first reset component abutment surface and the second reset component abutment surface, and its two ends abut against the first reset component abutment surface and the second reset component abutment surface, respectively.
[0051] By adopting the above technical solution, the arrangement of the first reset member abutment surface and the second reset member abutment surface enables the unlocking drive reset member to better function as the unlocking drive member.
[0052] Furthermore, a reset guide post is provided on the side of the first reset member abutting the second reset member abutting the second reset member abutting the first reset member abutting the second reset member abutting the first reset member abutting the second reset member abutting the first reset member abutting the second reset member abutting the second reset member abutting the first reset member abutting the second reset member abutting the third ...
[0053] By adopting the above technical solution, the setting caused by the reset component can prevent the unlocking drive reset component from twisting, ensuring that it can work more stably and reliably.
[0054] Furthermore, the drive unit mounting base is provided with a first abutment part, and the unlocking drive unit is provided with a second abutment part. The first abutment part and the second abutment part are arranged opposite to each other, and the first abutment part is arranged closer to the head of the storage box cover than the second abutment part. When the unlocking drive unit is in normal condition, the first abutment part and the second abutment part abut against each other.

[0115] Furthermore, the storage box locking mechanism 300 includes a locking structure reset member 8, which acts on the locking structure 1 to make the locking structure 1 tend to move toward the locking engagement structure 2.
[0116] By adopting the above technical solution, the setting of the locking structure reset member 8 makes the locking structure 1 tend to move towards the locking mating structure 2; specifically, the locking structure reset member 8 is an elastic member.
[0117] Furthermore, the locking structure 1 can be slidably disposed relative to the storage box cover 200 along the width direction of the storage box cover 200, so that it moves closer to and away from the locking engagement structure 2 when the storage box cover 200 closes the access opening 100-2 of the storage box cover 200.
[0118] The unlocking structure 5 includes an unlocking drive member 501, which is disposed on the storage box cover 200. The unlocking drive member 501 is slidable relative to the storage box cover 200 along the length direction of the storage box cover 200. The unlocking drive member 501 is provided with a first unlocking engagement part 501-1. Correspondingly, the locking structure 1 is provided with a second unlocking engagement part 101 that contacts and engages with the first unlocking engagement part 501-1. The first unlocking engagement part 501-1 and the second unlocking engagement part 101 cooperate to convert the sliding movement of the unlocking drive member 501 into the sliding movement of the locking structure 1.
[0119] Using the above technical solution, when the locking structure 1 slides along the width direction of the storage box cover 200 so that the locking pin 3 is inserted into the locking groove 4, the storage box cover 200 can be restricted from sliding along its length direction, so as to lock it in the state of closing the storage box body 100's access opening 100-2.
[0120] The unlocking drive 501 slides along the length of the storage box cover 200 to drive the sliding of the locking structure 1, thereby disengaging the locking pin 3 from the locking groove 4 to unlock. The above technical solution makes it more convenient and easier for users to operate the unlocking drive 501.
[0121] Furthermore, one of the first unlocking engagement portion 501-1 and the second unlocking engagement portion 101 is configured as an unlocking ramp 9, and the other of the first unlocking engagement portion 501-1 and the second unlocking engagement portion 101 is configured as an unlocking protrusion 10.
[0122] By adopting the above technical solution, the arrangement of the first unlocking engagement part 501-1 and the second unlocking engagement part 101 is more reasonable, so that the two can cooperate to realize the sliding motion of the unlocking drive member 501 into the sliding motion of the locking structure 1; specifically, the first unlocking engagement part 501-1 is configured as the unlocking inclined surface 9, and the second unlocking engagement part 101 is configured as the unlocking protrusion 10.
[0123] Furthermore, the first unlocking engagement part 501-1 cooperates with the second unlocking engagement part 101 to convert the sliding motion of the unlocking drive member 501 towards the tail side of the storage box cover 200 into the sliding motion of the locking structure 1 towards the side away from the locking engagement structure 2.
[0124] By adopting the above technical solution, the cooperation between the unlocking drive component 501 and the locking structure 1 is more reasonable, making it more convenient and easy for the user to operate the unlocking drive component 501 to disengage the locking pin 3 from the locking slot 4.
[0125] Furthermore, along the direction from the head to the tail of the storage box cover 200, the unlocking ramp 9 gradually tilts towards the locking structure 1 in a direction away from the locking engagement structure 2.
[0126] By adopting the above technical solution, the unlocking slope 9 is made more reasonable, so that when the user operates the unlocking drive 501 to slide towards the rear of the storage box cover 200, the unlocking slope 9 cooperates with the locking protrusion to make the locking pin 3 disengage from the locking groove 4.
[0127] Furthermore, there are two locking structures 1, which are arranged opposite to each other. One of the locking pins 3 and the locking groove 4 is provided at the ends of the two locking structures 1 that are far apart from each other. The locking structure reset member 8 is arranged between the two locking structures 1, and the two ends of the locking structure reset member 8 abut against the ends of the two locking structures 1 that are close to each other. Correspondingly, there are two locking mating structures 2.
[0128] By adopting the above technical solution, the locking structure 1 and the locking engagement structure 2 are more reasonable. The two locking structures 1 and the two locking engagement structures 2 can more stably and reliably lock the storage box cover 200 in the state of closing the storage box body 100's access opening 100-2.
[0129] Furthermore, the above technical solution makes the setting of the locking structure reset member 8 more reasonable, so that the locking structure reset member 8 can act on the two locking structures 1.
[0130] Furthermore, the storage box locking mechanism 300 includes a connecting pin 11. The two locking structures 1 have a connecting sleeve groove 102 that matches the connecting pin 11 at their close ends. The connecting pin 11 is disposed between the two locking structures 1, and both ends of the connecting pin 11 are respectively inserted into the connecting sleeve groove 102 of the two locking structures 1. The locking structure reset member 8 is a spring, and the locking structure reset member 8 is sleeved on the connecting pin 11.
[0131] By adopting the above technical solution, the setting of the connecting pin 11 can play a certain guiding and restricting role in the sliding of the locking structure 1; at the same time, since the locking structure reset member 8 is sleeved on the connecting pin 11, the locking structure reset member 8 can be prevented from twisting, etc., so that the locking structure reset member 8 can work more stably and reliably.
[0132] Furthermore, the unlocking structure 5 includes an unlocking drive reset member 502, which acts on the unlocking drive member 501, causing it to have a tendency to slide towards the head side of the storage box cover 200 after sliding towards the tail side of the storage box cover 200.
[0133] By adopting the above technical solution, the unlocking drive reset component 502 is configured so that the unlocking drive component 501 can automatically reset after the user removes the force applied to the unlocking drive component 501.
[0134] Furthermore, the unlocking structure 5 includes a drive member mounting base 503 disposed on the storage box cover 200, and the unlocking drive member 501 is slidably disposed on the drive member mounting base 503 along the length direction of the storage box cover 200.
[0135] By adopting the above technical solution, the unlocking structure 5 becomes more reasonable, and the driving component mounting base 503 provides an installation foundation for installing the unlocking driving component 501.
[0136] Furthermore, the unlocking drive component 501 is provided with sliding mating strips 501-2 on both sides, and the sliding mating strips 501-2 extend along the length direction of the storage box cover 200. Correspondingly, the mounting base is provided with sliding mating grooves 503-1 on both sides of the unlocking drive component 501 that match the sliding mating strips 501-2.
[0137] By adopting the above technical solution, the cooperation between the sliding mating strip 501-2 and the sliding mating groove 503-1 can guide the sliding of the unlocking drive 501 and restrict the movement of the unlocking drive 501 in other directions, so that the unlocking drive 501 can be stably and reliably installed on the drive mounting base 503.
[0138] Furthermore, the drive mounting base 503 is provided with a first reset component abutment surface 503-2, and the unlocking drive component 501 is provided with a second reset component abutment surface 501-3. The first reset component abutment surface 503-2 and the second reset component abutment surface 501-3 are arranged opposite to each other, and the second reset component abutment surface 501-3 is arranged closer to the head of the storage box cover 200 than the first reset component abutment surface 503-2. The unlocking drive reset component 502 is arranged between the first reset component abutment surface 503-2 and the second reset component abutment surface 501-3, and its two ends abut against the first reset component abutment surface 503-2 and the second reset component abutment surface 501-3, respectively.
[0139] By adopting the above technical solution, the arrangement of the first reset member abutment surface 503-2 and the second reset member abutment surface 501-3 enables the unlocking drive reset member 502 to better act on the unlocking drive member 501.
[0140] Furthermore, a reset member guide post 504 is provided on the first reset member abutment surface 503-2 toward the second reset member abutment surface, or a reset member guide post 504 is provided on the second reset member abutment surface 501-3 toward the first reset member abutment surface, and the unlocking drive reset member 502 is a spring and sleeved on the reset member guide post 504.
[0141] By adopting the above technical solution, the setting caused by the reset component can prevent the unlocking drive reset component 502 from twisting, ensuring that it can work more stably and reliably.
[0142] Furthermore, the drive unit mounting base 503 is provided with a first abutting part 503-3, and the unlocking drive unit 501 is provided with a second abutting part 501-4. The first abutting part 503-3 and the second abutting part 501-4 are disposed opposite to each other, and the first abutting part 503-3 is disposed closer to the head of the storage box cover 200 than the second abutting part 501-4. When the unlocking drive unit 501 is in its normal state, the first abutting part 503-3 abuts against the second abutting part 501-4.
[0143] By adopting the above technical solution, the arrangement of the first abutting part 503-3 and the second abutting part 501-4 can limit the interaction range of the unlocking drive 501 and ensure the overall stability and reliability of the unlocking structure 5.
[0144] Furthermore, the unlocking drive 501 and the locking structure 1 are respectively disposed on the upper and lower sides of the drive mounting base 503, and the drive mounting base 503 is provided with an unlocking mating hole 503-4 through which the unlocking protrusion 10 passes to engage with the unlocking inclined surface 9.
[0145] By adopting the above technical solution, the setting of the unlocking mating hole 503-4 allows the unlocking protrusion 10 to pass through the unlocking mating hole 503-4 and engage with the unlocking inclined surface 9.
[0146] Furthermore, the drive component mounting base 503 is provided with a locking structure mounting cavity 503-5 for mounting the locking structure 1 at the location where the locking structure 1 is set, and the side of the drive component mounting base 503 is provided with a drive component mounting base through hole 503-6 that communicates with the locking structure mounting cavity 503-5 so that one end of the locking structure 1, where the locking post 3 or the locking groove 4 is set, extends out of the drive component mounting base 503.
[0147] By adopting the above technical solution, the installation and cooperation between the drive component mounting base 503 and the locking structure 1 are made more reasonable.
