Description

Technical Field

[0001] The utility model belongs to the technical field of luggage case locks, and more specifically, relates to a locking structure, a lock and a luggage case. Background Art

[0002] To facilitate the placement of items, a luggage compartment is typically located behind or on the side of a vehicle such as a motorcycle or electric vehicle. A luggage compartment typically includes a body and a lid that covers the body opening. A switch lock is provided on the body, which locks or unlocks with a hook on the lid to close or open the lid.

[0003] However, with existing luggage locks, after the switch lock and the lock hook are separated, the trunk lid remains closed on the trunk body. Users cannot visually determine whether the switch lock and the lock hook are unlocked by the trunk lid's status, and must manually rotate the trunk lid to confirm the unlocking success. Furthermore, to improve the sealing effect, existing luggage trunks generally have a sealing edge at the trunk opening, which is inserted into the trunk lid. Therefore, a large turning force is required to separate the trunk lid from the sealing edge. Furthermore, for some larger suitcases, the trunk lid is inevitably very heavy, further exacerbating the difficulty of opening the trunk lid. If the user lacks physical strength, they may not be able to open the trunk lid smoothly and may need to use external force or tools, which seriously affects the user experience. Utility Model Content

[0004] The purpose of the present utility model is to provide a locking structure, a lock and a luggage case, aiming to solve the problem in the prior art that after the switch lock and the lock hook are unlocked, the case lid is still covered on the case body, not only making it impossible to intuitively judge whether the unlocking is successful, but also requiring a large force to separate the case body and the case lid, making it difficult for the user to open the case lid.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

Unless otherwise expressly limited, the terms "fixed connection" or "fixed connection" used in the claims, specification, and drawings of this utility model should be broadly interpreted to mean any connection without displacement or relative rotation between the two parts, including non-detachable fixed connection, detachable fixed connection, integral connection, and fixed connection via other devices or elements. The terms "including," "having," and their variations used in the claims, specification, and drawings of this utility model are intended to mean "including but not limited to."

[0045] Please also refer to Figures 1 to 6 The locking structure, lock, and luggage provided by the present invention are now described. The locking structure includes a lock frame 5 and a drive member 4, as well as a locking assembly 1 and a pushing assembly 2. The locking assembly 1 is rotatably connected to the lock frame 5 and includes a locking portion that engages with the hook 3. The drive member 4 controls the rotation of the locking assembly 1 to engage or disengage the locking portion with the hook 3. The pushing assembly 2 includes a fixed seat 201 and a push rod 203 slidably connected to the fixed seat 201. The pushing assembly 2 also includes a first elastic member 202 connected to the push rod 203. The first elastic member 202 is configured with a preload force that causes the push rod 203 to push the hook 3.

[0046] Compared with the prior art, the locking structure provided by the present invention controls the rotation of the locking assembly 1 through the driving member 4. When the locking assembly 1 rotates until the locking portion engages with the hook 3, it is in a locked state; when the locking assembly 1 rotates until the locking portion separates from the hook 3, it is in an unlocked state. In the unlocked state, the push rod 203 applies a pushing force to the hook 3 under the action of the first elastic member 202, causing the box lid to rotate toward the side away from the box body, thereby opening the box lid. The present invention opens the box lid through the pushing assembly 2 in the unlocked state, and it can intuitively determine whether the unlocking is successful, avoiding the problem of manually rotating the box lid in the case of unlocking failure, resulting in low opening efficiency, or even damage to the locking structure or the suitcase. In addition, the present invention does not require manual separation of the box lid and the box body, reducing the labor required to open the box lid.

[0047] Optionally, the driver 4 can be an electronic device or a mechanical device. When the driver 4 is an electronic device, a motor can be used to drive the locking assembly 1 to rotate. When the driver 4 is a mechanical device, an external force is applied to the driver 4 to cause the driver 4 to rotate or slide, and the driver 4 then applies force to the locking assembly 1 to control the rotation of the locking assembly 1.

[0048] Optionally, the first elastic member 202 is a spring.

[0049] Optionally, the locking structure is provided on the box body, and the hook 3 is provided on the box cover, and the box cover and the box body are kept closed by the engagement of the locking portion and the hook 3 .

[0050] As a specific embodiment of the pushing assembly 2, the fixing seat 201 is provided with a mounting hole, the push rod 203 is provided with a limiting plate 2031 on the outside, the push rod 203 is inserted into the mounting hole, and the first elastic member 202 is sleeved on the outside of the push rod 203 and respectively abuts against the limiting plate 2031 and the fixing seat 201, so that the push rod 203 has a pre-tightening force to push the box cover.

[0051] After the locking assembly 1 is separated from the lock hook, the first elastic member 202 is reset, and the push rod 203 slides under the action of the first elastic member 202 until the limiting piece 2031 abuts against the mounting seat, so that the push rod 203 applies a pushing force to the box cover, thereby separating the box cover from the box body.

[0052] In some embodiments, see Figures 1 to 4 The locking assembly 1 includes a first locking member 101, a second locking member 102 and a reset mechanism 103. The first locking member 101 is rotatably connected to the lock frame 5. The locking portion is provided on the first locking member 101. The first locking member 101 is provided with a locking groove 1013 and an unlocking groove 1012. The second locking member 102 is rotatably connected to the lock frame 5. The second locking member 102 has a locking arm 1021 and a transmission block 1022. The driving member 4 is coupled to the transmission block 1022. 22 applies force to control the second locking member 102 to rotate, so that the locking arm 1021 is engaged with the locking groove 1013 or the unlocking groove 1012; the reset mechanism 103 is configured with a pre-tightening force to engage the locking arm 1021 with the locking groove 1013; the locking arm 1021 is engaged with the locking groove 1013, the locking part is engaged with the hook 3, and is in a locked state; the locking arm 1021 is engaged with the unlocking groove 1012, the locking part is separated from the hook 3, and is in an unlocked state.

[0053] When the locking arm 1021 engages the locking slot 1013, the locking portion of the first locking member 101 engages the hook 3, and the luggage is now in the locked state. To unlock, the driver 4 applies force to the transmission block 1022, causing the second locking member 102 to rotate. As the second locking member 102 rotates, the locking arm 1021 engages the unlocking slot 1012, and the locking portion separates from the hook 3, switching to the unlocked state. In this embodiment, the reset mechanism 103 maintains the locking arm 1021 in the locked state, maintaining engagement with the locking slot 1013. This means that the locking portion engages the hook 3 without the need for external force, preventing the loss of items within the luggage compartment.

[0054] Optionally, the first locking member 101 has a locking hook, which forms a locking portion and engages with the hook 3 .

[0055] In some embodiments, see Figures 1 to 4 The reset mechanism 103 includes a first reset member 1031 and a second reset member 1032. The first reset member 1031 is connected to the first locking member 101, and the first reset member 1031 is configured with a pre-tightening force that keeps the locking portion and the hook 3 separated; the second reset member 1032 is connected to the second locking member 102, and the second reset member 1032 is configured with a pre-tightening force that keeps the locking arm 1021 and the locking groove 1013 engaged.

[0056] When switching from the locked state to the unlocked state, the driver 4 applies force to the transmission block 1022. After the second locking member 102 rotates and separates from the locking groove 1013, the first locking member 101 rotates under the action of the first return member 1031 until the unlocking groove 1012 engages with the locking arm 1021. At this time, the hook 3 separates from the locking portion, switching to the unlocked state. When switching from the unlocked state to the locked state, the hook 3 applies pressure to the first locking member 101. After the first locking member 101 rotates until the unlocking groove 1012 separates from the locking arm 1021, the second locking member 102 rotates under the action of the second return member 1032 until the locking arm 1021 engages with the locking groove 1013, switching to the locked state. This embodiment relies on the elastic return force of the first return member 1031 and the second return member 1032 to achieve switching between the locked and unlocked states, avoiding the phenomenon of sticking during the switching process.

[0057] Specifically, the first restoring member 1031 and the second restoring member 1032 have opposite restoring directions.

[0058] Optionally, the first restoring member 1031 and the second restoring member 1032 are not spring-wound.

[0059] In some embodiments, see Figure 4 The first locking member 101 is provided with a locking groove 1011 , which forms a locking portion. The locking assembly 1 further includes a buffer pad 104 disposed in the locking groove 1011 .

[0060] In this embodiment, a buffer pad 104 is provided in the locking groove 1011. After the hook 3 is locked with the locking groove 1011, it contacts the buffer pad 104, avoiding direct contact with the first locking component 101, reducing abnormal noise generated by the rigid contact between the hook 3 and the first locking component 101 when locking or unlocking, reducing noise, and at the same time helping to protect the first locking component 101 and the hook 3 from wear.

[0061] Optionally, the buffer pad 104 is a rubber component or a nylon component, or may be an EVA component.

[0062] Based on the same inventive concept, the present invention also provides a lock. Figures 5 and 6 The lock includes any one of the locking structures described above, and there are multiple locking structures. It also includes a linkage structure 6 connected to multiple driving members 4, and the linkage structure 6 controls the actions of multiple driving members 4 at the same time.

[0063] The lock provided by the present invention adopts the above-mentioned locking structure. The locking assembly 1 is controlled to rotate by the driving member 4. When the locking assembly 1 rotates until the locking portion engages with the hook 3, it is in the locked state; when the locking assembly 1 rotates until the locking portion separates from the hook 3, it is in the unlocked state. In the unlocked state, the push rod 203 applies a pushing force to the hook 3 under the action of the first elastic member 202, causing the box lid to rotate toward the side away from the box body, thereby opening the box lid. The present invention opens the box lid in the unlocked state through the pushing assembly 2, which allows intuitive judgment of whether the unlocking is successful. This avoids the problem of manually rotating the box lid in the event of unlocking failure, resulting in low opening efficiency and even damage to the locking structure or the suitcase. In addition, the present invention does not require manual separation of the box lid and the box body, reducing the labor required to open the box lid. For larger suitcases, providing multiple locking mechanisms can increase the secureness of the lock between the box body and the lid, not only avoiding the problem of accidental opening of the suitcase, but also improving the sealing performance.

[0064] It should be noted that when the driving members 4 are electronic devices, the linkage structure 6 controls multiple driving members 4 to start simultaneously, respectively applying force to the corresponding locking components 1. When the driving members 4 are mechanical devices, the linkage structure 6 controls multiple driving members 4 to rotate or slide to apply force to the corresponding locking components 1.

[0065] In some embodiments, see Figures 5 and 6 The linkage structure 6 includes a fixed frame 601 and a linkage rod 602. The fixed frame 601 is installed on the box body. Multiple locking structures are distributed on the fixed frame 601 in sequence. The lock frame 5 is connected to the fixed frame 601; the linkage rod 602 is rotatably connected to the fixed frame 601, and the linkage rod 602 is connected to multiple driving parts 4.

[0066] Multiple locking brackets 5 are sequentially spaced apart on the fixed bracket 601, achieving multi-point connection between the box body and the lid, further enhancing the seal and secureness of the box body and lid when closed. Linking rods 602 are connected to the multiple driving members 4, respectively. Rotation of the linkage rods 602 synchronizes the rotation or movement of the multiple driving members 4. This embodiment avoids hysteresis when multiple locking mechanisms are unlocked or unlocked, ensuring that the multiple locking mechanisms are locked or unlocked synchronously, allowing the lid and box body to be closed or opened.

[0067] Optionally, force may be applied to the linkage rod 602 manually or by a driving component.

[0068] In some embodiments, see Figures 5 and 6 The linkage structure 6 also includes a control component, which includes a controller, an operation terminal and a driver 604; the operation terminal is connected to the controller for communication; the driver 604 is connected to the controller for communication, and the driver 604 controls the rotation of the linkage rod 602.

[0069] The operation terminal sends an opening command to the controller. The controller controls the driver 604 to apply force to the linkage rod 602 according to the opening command. The linkage rod 602 rotates, causing the driver 4 to control the rotation of the locking assembly 1, thereby separating the locking portion from the hook 3. After the locking portion is separated from the hook 3, in this embodiment, the locking portion and the hook 3 can be separated by the operation terminal to achieve unlocking, which is more convenient and quick.

[0070] Specifically, the controller may be a control module separately provided in the trunk, or may be the control system of the entire vehicle.

[0071] Optionally, the driver 604 abuts against the transmission block 1022.

[0072] Optionally, the operating terminal may be an operating system in the vehicle, or a handheld operating terminal such as a mobile phone, an electronic key, etc.

[0073] Optionally, in this embodiment, the driving member 4 is a mechanical component.

[0074] In some embodiments, see Figures 5 and 6 The linkage structure 6 also includes a traction member 603 and a second elastic member. The traction member 603 is slidably or rotationally connected to the fixed frame 601 and is rotationally connected to the linkage rod 602. The traction member 603 controls the rotation of the linkage rod 602; the second elastic member is respectively connected to the linkage rod 602 and the fixed frame 601, and the second elastic member is configured with a pre-tightening force to keep the linkage rod 602 in a stationary state.

[0075] This embodiment applies force to the traction member 603, facilitating the rotation of the linkage rod 602. This in turn enables the driver 4 to control the rotation of the locking assembly 1, achieving separation of the locking portion from the hook 3. When the locking portion is engaged with the hook 3, the traction member 603 is not subject to external forces and does not apply force to the linkage rod 602. The second elastic member maintains the linkage rod 602 in a stationary state, preventing it from rotating under vibration, which could cause the locking assembly 1 to rotate and the locking portion to separate from the hook 3. Furthermore, the provision of the second elastic member prevents the linkage rod 602 from shaking and producing unusual noises under vibration.

[0076] It should be noted that only one traction member 603 can be provided. When the traction member 603 drives the linkage rod 602 to rotate, transmission lag or jamming may occur due to the different spacings between the multiple locking structures and the traction member 603. Under the action of the second elastic member, the linkage shaft can simultaneously drive multiple driving members 4, thereby achieving synchronous unlocking of multiple locking assemblies 1.

[0077] Optionally, the second elastic member is a spring.

[0078] In some embodiments, not shown in the figures, the lock further includes a prompt module provided on the lock frame 5 , the prompt module is communicatively connected with the controller, and in the unlocked state, the prompt module sends a prompt signal.

[0079] When the driver 605 controls the locking structure to be in the unlocked state, an unlocking signal is generated, and the controller 604 controls the prompt module to send a prompt signal to the outside according to the unlocking signal.

[0080] Optionally, the prompt module sends a light wave or sound wave prompt signal.

[0081] Optionally, the lock further includes a status switch 605 provided on the lock frame 5 , the status switch 605 is respectively connected to the controller for communication, and the status switch 605 is used to detect the switch state of the locking structure.

[0082] After unlocking, status switch 605 closes and generates a first signal. Based on the first signal, the controller controls the prompt module to issue a prompt signal. After locking, status switch 605 opens and generates a second signal. Based on the second signal, the controller controls the prompt module to no longer issue a prompt signal. Based on the same inventive concept, the present invention also provides a suitcase. The suitcase includes any of the aforementioned locks.

[0083] The luggage case provided by the present invention utilizes the aforementioned lock. The locking assembly 1 is controlled to rotate by a driving member 4. When the locking assembly 1 rotates until the locking portion engages the hook 3, the case is locked. When the locking assembly 1 rotates until the locking portion separates from the hook 3, the case is unlocked. In the unlocked state, the push rod 203, under the action of the first elastic member 202, applies a pushing force to the hook 3, causing the case lid to rotate toward the side away from the case body, thereby opening the case lid. The present invention opens the case lid in the unlocked state through the pushing assembly 2, allowing for intuitive judgment of unlocking success. This avoids the problem of manually rotating the case lid in the event of unlocking failure, resulting in inefficient opening and even damage to the locking structure or the case. Furthermore, the present invention eliminates the need for manual separation of the case lid from the case body, reducing the labor required to open the case lid. For larger suitcases, providing multiple locking mechanisms can increase the secureness of the lock between the case body and the lid, not only preventing the case from being accidentally opened but also improving sealing performance.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
