Description
Technical Field
[0001] This utility model relates to the field of pickup truck roll-up cover technology, and in particular to a pickup truck top roll-up cover push-button lock. Background Technology
[0002] In the automotive industry, pickup trucks, with their dual function of carrying both passengers and cargo, are widely used in various scenarios such as commercial transportation, outdoor operations, and off-road travel. As the core area for fulfilling the cargo-carrying function, the safety and convenience of the pickup truck's cargo bed have always been a key concern for users. To address the issues of exposed cargo beds leading to susceptibility to external environmental factors and insufficient safety, pickup truck roll-up covers have emerged as an important cargo bed modification accessory and have now become essential equipment for many pickup truck users. The pickup truck roll-up cover is installed on top of the pickup truck bed, providing full coverage through a retractable roll-up structure. Its core functions are multifaceted. First, in terms of environmental protection, a high-quality pickup truck roll-up cover effectively prevents rainwater and dust from entering the cargo bed, avoiding damage to goods due to moisture or dust. Simultaneously, its sun-blocking properties prevent items inside the cargo bed from fading or deteriorating due to prolonged exposure to sunlight, such as food and outdoor equipment, greatly extending the lifespan of the goods. Second, in terms of improved appearance and practicality, the pickup truck roll-up cover makes the pickup truck bed lines smoother, giving it a more refined overall look and enhancing the vehicle's visual appeal. More importantly, the roll-up cover also offers rich expansion capabilities. By installing crossbars, multi-functional gantry frames, and other expansion media, it can secure and carry various outdoor items such as bicycles, camping equipment, and suitcases, further expanding the pickup truck's usage scenarios and meeting diverse user travel and transportation needs. In the overall structure of a pickup truck roll-up cover, the lock is one of the core components ensuring its functionality. The main function of the lock is to securely connect the roll-up cover to the cargo box via a locking device when the cover is closed, ensuring the cover remains stable during vehicle movement. However, market research and analysis of actual usage of existing pickup truck roll-up cover locks have revealed significant deficiencies in structural design and performance, failing to meet users' needs for locking security and safety. The main problems are as follows: First, existing locks generally suffer from insecure locking. Limited by inadequate locking structure design, such as insufficient engagement depth between the bolt and latch, and insufficient rigidity of the locking mechanism, lock components are prone to wear and deformation during long-term use, leading to a gradual decrease in locking effectiveness. When pickup trucks travel on unpaved roads, rural dirt roads, or other bumpy sections, the continuous vibrations from the vehicle constantly impact the locking parts of the lock, easily causing the bolt and latch to disengage, thus triggering the roller shutter cover lock to open unexpectedly. This not only exposes the cargo inside the cargo box to the external environment, risking rainwater soaking and dust contamination, but if the cargo is not secured, it may also fall out of the cargo box due to vehicle bumps, causing damage. Furthermore, fallen cargo may pose a safety hazard to following vehicles, seriously threatening road traffic safety. Secondly, most existing pickup truck roll-up door locks use a one-step unlocking design, such as unlocking by simply pressing a button. While this design offers some convenience, it poses a significant risk of accidental activation. During daily use, when operators are loading or unloading cargo, cleaning the vehicle, or checking the cargo area, their arms, bodies, or tools can easily and accidentally touch the unlock button, causing the lock to mis-lock and open the roll-up door. From a cargo protection perspective, mis-locking leaves the cargo uncovered without any warning. If the vehicle is parked, this could lead to theft; if the vehicle is in motion, it could cause similar problems as accidental unlocking, such as cargo falling out and jeopardizing driving safety. From the perspective of expanding functionality, when users have already installed crossbars, gantry frames, or other expansion media on the roller shutter cover and secured outdoor equipment, the accidental opening of the roller shutter can cause the expansion media and outdoor equipment to lose support, potentially resulting in damage to the expansion media and the outdoor equipment falling off. This not only leads to economic losses but may also cause safety accidents, seriously affecting users' experience and trust in the expansion function of the pickup truck roller shutter cover.
[0003] Therefore, it is necessary to provide a secure and reliable push-button lock for pickup truck roof roll-up blinds. Utility Model Content
[0004] The purpose of this utility model is to provide a pickup truck roof roll-up push-button lock that is secure and safe.
[0005] To achieve the above objectives, this utility model provides a push-button lock for a pickup truck roof roller shutter, characterized in that it includes a base, a lock head assembly, a sliding member, a linkage mechanism, a first elastic member, a first unlocking mechanism, and a second unlocking mechanism; the lock head assembly is rotatably connected to the base and is used to engage with an external component for locking; the sliding member is slidably disposed on the base; one end of the linkage mechanism is movably connected to the sliding member, and the other end of the linkage mechanism is rotatably connected to the lock head assembly; the first elastic member is connected between the sliding member and the base and is used to provide an elastic force that drives the sliding member to move away from the base; the first unlocking mechanism passes through the sliding member, and the middle part of the first unlocking mechanism rotates. Connected to the sliding member, one end of the first unlocking mechanism is exposed on the outside of the sliding member, and the other end of the first unlocking mechanism is engaged with the seat and limits the sliding member to the position where it presses the first elastic member, thereby limiting the lock assembly to the locked position; the second unlocking mechanism is movably disposed on the seat and engages with the sliding member and limits the sliding member to the position where it presses the first elastic member; by driving the second unlocking mechanism to move and disengage from the sliding member, and by driving the first unlocking mechanism to rotate and disengage from the seat, the sliding member slides under the elastic force of the first elastic member and drives the linkage mechanism to move, thereby driving the lock assembly to rotate and achieve unlocking.
[0006] Preferably, the lock assembly includes a lock cylinder lever and a lock cylinder body. The lock cylinder lever is rotatably connected to the base, and the lock cylinder body is disposed on the lock cylinder lever. The lock cylinder body is used to insert and cooperate with external components to achieve locking. Preferably, the linkage mechanism includes a first link and a second link, the sliding member is provided with a connecting shaft, one end of the first link is provided with a movable groove, the first link is sleeved on the connecting shaft through the movable groove and can slide and swing relative to the sliding member, the middle part of the first link is rotatably connected to the base, the other end of the first link is rotatably connected to one end of the second link, and the other end of the second link is rotatably connected to the lock head assembly. Preferably, the base is provided with a sliding groove, and the connecting shaft is slidably inserted into the sliding groove. Preferably, the first unlocking mechanism includes an unlocking press and an unlocking lever. The unlocking press is disposed on the outer side of the sliding member, and the unlocking lever passes through the sliding member. One end of the unlocking lever is connected to the unlocking press, and the other end of the unlocking lever is engaged with the seat. By pressing the unlocking press, the unlocking lever is driven to rotate, thereby disengaging the unlocking lever from the seat. Preferably, the base is provided with a first locking hole, and the unlocking lever is provided with a hook, which engages with the first locking hole. Preferably, the first unlocking mechanism further includes a second elastic element, which is connected between the unlocking lever and the seat, and the second elastic element is used to provide an elastic force to drive the unlocking press to rotate and engage with the seat. Preferably, the second unlocking mechanism includes a lock cylinder and an unlocking movable component. The lock cylinder is rotatably mounted on the base. The lock cylinder has a locking structure that locks the lock cylinder onto the base and a keyhole for inserting a key and driving the locking structure to release the lock cylinder. The unlocking movable component is slidably mounted on the base and engages with the sliding component. The lock cylinder abuts against the unlocking movable component. By inserting the key into the keyhole and causing the locking structure to release the lock cylinder, the lock cylinder is driven to rotate and push the unlocking movable component to slide, causing the unlocking movable component to disengage from the sliding component. Preferably, the slider is provided with a second locking hole, and the unlocking movable part is inserted into the second locking hole and engages with the slider. Preferably, the lock cylinder has an eccentric protrusion offset from its rotation center, and the unlocking moving part has a connecting groove, with the eccentric protrusion inserted into the connecting groove; by driving the lock cylinder to rotate and driving the eccentric protrusion, the eccentric protrusion moves in the connecting groove and pushes the unlocking moving part to slide. Compared with existing technologies, the pickup truck roof roll-up push-button lock of this utility model, through the dual limiting design of the first unlocking mechanism and the second unlocking mechanism, forms a double locking constraint on the sliding member, and then stabilizes the lock head assembly in the locked position through the linkage mechanism. In the locked state, one end of the first unlocking mechanism engages with the seat body, initially fixing the sliding member at the position where it presses against the first elastic member; at the same time, the second unlocking mechanism engages with the sliding member, further reinforcing the position of the sliding member. This double locking structure greatly enhances the overall impact resistance and structural stability of the lock compared with the existing single locking method. When a pickup truck travels on bumpy roads, the vibrations generated by the vehicle will simultaneously affect the lock. However, the dual locking structure of the pickup truck roof roll-up push-lock of this utility model can effectively offset the impact of vibration on the locking state: on the one hand, the second unlocking mechanism can effectively share the vibration impact force borne by the first unlocking mechanism, avoiding wear and deformation of the single locking structure due to long-term concentrated force, and extending the service life of the lock; on the other hand, even if one of the first and second unlocking mechanisms becomes slightly loose due to extreme bumps, the other unlocking mechanism can still maintain the fixed state of the sliding part, ensuring that the lock head assembly always maintains a stable plug-in fit with the external parts, completely eliminating the problem of "accidental opening due to bumps" caused by the existing locks due to insecure locking, providing double security for the goods in the cargo box, and avoiding driving safety hazards caused by accidental opening of the roll-up curtain. Furthermore, the double-locking structure of this pickup truck roof roller shutter push-button lock effectively prevents accidental unlocking. A single unlocking action is insufficient to disengage the sliding member from the double restraints. Only after the second unlocking mechanism moves and disengages from the sliding member, and the first unlocking mechanism rotates and disengages from the seat, can the sliding member slide under the action of the first elastic member and, through the linkage mechanism, rotate the lock head assembly to release the lock. Therefore, this pickup truck roof roller shutter push-button lock features a secure locking mechanism and high security. Attached Figure Description

[0014] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0015] Please see Figures 1 to 6 The pickup truck roof roller shutter push-button lock 100 of this utility model includes a base 1, a lock head assembly 2, a sliding member 3, a linkage mechanism 4, a first elastic member 5, a first unlocking mechanism 6, and a second unlocking mechanism 7. The lock head assembly 2 is rotatably connected to the base 1 and is used to engage with external components to achieve locking. The sliding member 3 is slidably disposed on the base 1. One end of the linkage mechanism 4 is movably connected to the sliding member 3, and the other end of the linkage mechanism 4 is rotatably connected to the lock head assembly 2. The first elastic member 5 is connected between the sliding member 3 and the base 1 and is used to provide an elastic force to drive the sliding member 3 to move away from the base 1. The first unlocking mechanism 6 passes through the sliding member 3, and the middle part of the first unlocking mechanism 6 is rotatably connected to... On the sliding member 3, one end of the first unlocking mechanism 6 is exposed on the outside of the sliding member 3, and the other end of the first unlocking mechanism 6 is engaged with the base 1 and limits the sliding member 3 to the position where it compresses the first elastic member 5, thereby limiting the lock assembly 2 to the locked position. The second unlocking mechanism 7 is movably disposed on the base 1, and the second unlocking mechanism 7 is engaged with the sliding member 3 and limits the sliding member 3 to the position where it compresses the first elastic member 5. By driving the second unlocking mechanism 7 to move and disengage from the sliding member 3, and by driving the first unlocking mechanism 6 to rotate and disengage from the base 1, the sliding member 3 slides under the elastic force of the first elastic member 5 and drives the linkage mechanism 4 to move, thereby driving the lock assembly 2 to rotate and achieve unlocking. The above structure, through the coordinated cooperation of multiple components, realizes the functions of double locking and two-step unlocking, effectively improving the security and reliability of the lock.
[0016] Please see Figures 2 to 6In one embodiment, the lock assembly 2 includes a lock lever 21 and a lock body 22. The lock lever 21 is rotatably connected to the base 1, and the lock body 22 is disposed on the lock lever 21. The lock body 22 is used to engage with external components and achieve locking. The rotation of the lock lever 21 can drive the lock body 22 to move synchronously, so that the lock body 22 can accurately engage or disengage with external components (such as mounting plates on pickup truck cargo boxes), ensuring the stability of the locking and unlocking process.
[0017] Specifically, one end of the lock head lever 21 is rotatably connected to the base 1, the middle part of the lock head lever 21 is rotatably connected to the linkage mechanism 4, and the lock head body 22 is disposed on the other end of the lock head lever 21. This structural design allows the driving force of the linkage mechanism 4 to be transmitted to the lock head lever 21 more evenly, reducing the jamming phenomenon when the lock head lever 21 rotates, while making the movement trajectory of the lock head body 22 more reasonable and ensuring the accuracy of the insertion with external components.
[0018] Please see Figures 2 to 6 In one embodiment, the linkage mechanism 4 includes a first link 41 and a second link 42. A connecting shaft 31 is provided on the sliding member 3. One end of the first link 41 has a movable groove 411. The first link 41 is sleeved on the connecting shaft 31 through the movable groove 411 and can slide and swing relative to the sliding member 3. The middle part of the first link 41 is rotatably connected to the base 1. The other end of the first link 41 is rotatably connected to one end of the second link 42, and the other end of the second link 42 is rotatably connected to the lock assembly 2. The rotatable connection design of the first link 41 and the second link 42 can flexibly convert the linear motion of the sliding member 3 into the rotational motion of the lock assembly 2. The cooperation between the movable groove 411 and the connecting shaft 31 provides a certain buffer space for the movement of the linkage mechanism 4, avoiding excessive stress between components due to rigid connections and extending the service life of the mechanism.
[0019] Please see Figures 2 to 6 In one embodiment, the base 1 is provided with a sliding groove 11, and the connecting shaft 31 is slidably inserted into the sliding groove 11. The sliding groove 11 guides and limits the sliding of the connecting shaft 31, ensuring that the connecting shaft 31 drives the first connecting rod 41 to move along a preset trajectory, preventing the linkage mechanism 4 from deviating or jamming during operation, and ensuring the smoothness of the entire transmission process.
[0020] Please see Figure 4In one embodiment, the seat 1 is provided with a first limiting protrusion 12, and the slider 3 is provided with a second limiting protrusion 32 opposite to the first limiting protrusion 12. One end of the first elastic member 5 is sleeved on the first limiting protrusion 12 and abuts against the seat 1, and the other end of the first elastic member 5 is sleeved on the second limiting protrusion 32 and abuts against the slider 3. The first limiting protrusion 12 and the second limiting protrusion 32 can fix the first elastic member 5, preventing it from shifting or falling off during the extension and retraction process, ensuring that the first elastic member 5 can always provide a stable elastic driving force to the slider 3, and also making the transmission of elastic force more concentrated and effective.
[0021] Please see Figure 1 In one embodiment, the bottom of the base 1 is provided with a protective shell 14 for its protective function.
[0022] Please see Figures 2 to 6 In one embodiment, the first unlocking mechanism 6 includes an unlocking press 61 and an unlocking lever 62. The unlocking press 61 is disposed on the outer side of the sliding member 3, and the unlocking lever 62 passes through the sliding member 3. One end of the unlocking lever 62 is connected to the unlocking press 61, and the other end of the unlocking lever 62 is engaged with the seat 1. By pressing the unlocking press 61, the unlocking lever 62 is driven to rotate, causing the unlocking lever 62 to disengage from the seat 1. The unlocking press 61 is exposed on the outside, making it convenient for the operator to apply external force, while the rotation of the unlocking lever 62 can quickly achieve engagement or disengagement with the seat 1. This structure is simple and intuitive, easy to operate, and can effectively improve unlocking efficiency.
[0023] Specifically, in one embodiment, the base 1 is provided with a first locking hole 13, and the unlocking lever 62 is provided with a hook 621, which engages with the first locking hole 13. The engagement between the hook 621 and the first locking hole 13 is tight and reliable, which can stably limit the sliding member 3 to the locked position. At the same time, when the unlocking lever 62 rotates, the hook 621 can smoothly disengage from the first locking hole 13, ensuring the sensitivity of the unlocking action.
[0024] Furthermore, in one embodiment, the first unlocking mechanism 6 further includes a second elastic element 63, which is connected between the unlocking lever 62 and the base 1. The second elastic element 63 provides an elastic force to drive the unlocking press 61 to rotate and engage with the base 1. Through the elastic force of the second elastic element 63, the unlocking lever 62 can be held engaged in the first locking hole 13. When the first unlocking mechanism 6 needs to release the sliding member 3, pressing the unlocking press 61 drives the unlocking lever 62 to squeeze the second elastic element 63 and rotate against the elastic force of the second elastic element 63, causing the hook 621 of the unlocking lever 62 to disengage from the first locking hole 13, thereby unlocking the first unlocking mechanism 6 and achieving the purpose of releasing the sliding member 3.
[0025] Specifically, in one embodiment, the unlocking lever 62 is provided with a positioning hole 622. One end of the second elastic member 63 is inserted into the positioning hole 622 and abuts against the unlocking lever 62, while the other end of the second elastic member 63 abuts against the sliding member 3. The positioning hole 622 positions the second elastic member 63, preventing it from shifting during deformation and ensuring that the second elastic member 63 can provide a stable reset force for the unlocking lever 62, thus ensuring the reliable reset effect of the first unlocking mechanism 6.
[0026] Please see Figures 4 to 7 In one embodiment, the second unlocking mechanism 7 includes a lock cylinder 71 and an unlocking movable member 72. The lock cylinder 71 is rotatably mounted on the base 1. The lock cylinder 71 has a locking structure 711 that locks the lock cylinder 71 onto the base 1, and a keyhole 712 for inserting a key 200 to drive the locking structure 711 to release the lock cylinder 71. The unlocking movable member 72 is slidably mounted on the base 1 and engages with a sliding member 3. The lock cylinder 71 abuts against the unlocking movable member 72. By inserting the key 200 into the keyhole 712 and causing the locking structure 711 to release the lock cylinder 71, the lock cylinder 71 is driven to rotate and push the unlocking movable member 72 to slide, causing the unlocking movable member 72 to disengage from the sliding member 3. The cooperation between the lock cylinder 71 and the key increases the security of the second unlocking mechanism 7. Only a matching key can drive the lock cylinder 71 to rotate, thereby unlocking and disengaging the movable member 72 from the sliding member 3, effectively preventing unauthorized personnel from misoperating or maliciously unlocking the lock.
[0027] Specifically, in one embodiment, the slider 3 is provided with a second locking hole 33, and the unlocking moving part 72 is inserted into the second locking hole 33 and engages with the slider 3. This engaging method has a simple structure, can effectively restrict the movement of the slider 3, and can be quickly pulled out from the second locking hole 33 when the unlocking moving part 72 slides, ensuring the timeliness and reliability of the unlocking action.
[0028] Specifically, in one embodiment, the lock cylinder 71 is provided with an eccentric protrusion 713 that is off-center from its rotation center, and the unlocking moving part 72 is provided with a connecting groove 721, into which the eccentric protrusion 713 is inserted; by driving the lock cylinder 71 to rotate and driving the eccentric protrusion 713, the eccentric protrusion 713 moves in the connecting groove 721 and pushes the unlocking moving part 72 to slide, thereby achieving disengagement from the sliding part 3.
[0029] Furthermore, in one embodiment, the second unlocking mechanism 7 further includes a protective cover 73, which is rotatably connected to the base 1 and used to cover the keyhole 712. The protective cover 73 can effectively prevent dust, rainwater and other impurities from entering the keyhole 712, avoiding malfunctions of the lock cylinder 71 due to blockage. At the same time, it can also prevent foreign objects from accidentally touching the internal structure of the keyhole 712, protecting the normal function and service life of the lock cylinder 71.
[0030] Combination Figures 1 to 7 The specific working principle of the pickup truck roof roller shutter push-lock 100 of this utility model is as follows: In the locked state, the hook 621 of the unlocking lever 62 of the first unlocking mechanism 6 engages with the first locking hole 13 of the base 1, and the unlocking moving part 72 of the second unlocking mechanism 7 is inserted into the second locking hole 33 of the sliding part 3. The double locking action limits the sliding part 3 to the position of pressing the first elastic part 5. At this time, the first elastic part 5 is in a compressed state and stores elastic potential energy. At the same time, the sliding part 3 drives the lock head assembly 2 to remain in the locked position of being inserted and engaged with the external part through the linkage mechanism 4. When unlocking is required, firstly, the key 200 is inserted into the keyhole 712 of the lock cylinder 71 of the second unlocking mechanism 7, causing the locking structure 711 to release and drive the lock cylinder 71 to rotate. The eccentric protrusion 713 on the lock cylinder 71 rotates accordingly and pushes the unlocking moving part 72 to slide, causing the unlocking moving part 72 to disengage from the second locking hole 33 of the sliding part 3, completing the second unlocking. Then, the unlocking pressing part 61 of the first unlocking mechanism 6 is pressed, driving the unlocking swing rod 62 to rotate and squeezing the second elastic member 63, causing the hook 621 of the unlocking swing rod 62 to disengage from the first locking hole 13 of the base body 1, completing the first unlocking. At this time, the sliding part 3 slides away from the base body 1 under the elastic force of the first elastic member 5, driving the lock head assembly 2 to rotate through the linkage mechanism 4, causing the lock head assembly 2 to disengage from the external parts and realize overall unlocking.
[0031] In summary, the pickup truck roof roller shutter push-button lock 100 of this utility model, through the dual limiting design of the first unlocking mechanism 6 and the second unlocking mechanism 7, forms a double locking constraint on the sliding member 3, and then stabilizes the lock head assembly 2 in the locked position through the linkage mechanism 4. In the locked state, one end of the first unlocking mechanism 6 engages with the seat 1, initially fixing the sliding member 3 at the position where it compresses the first elastic member 5; at the same time, the second unlocking mechanism 7 engages with the sliding member 3, further reinforcing the position of the sliding member 3. Compared with the existing single locking method, this double locking structure 711 greatly enhances the overall impact resistance and structural stability of the lock. When a pickup truck travels on bumpy roads, the vibrations generated by the vehicle will simultaneously affect the lock. However, the double locking structure 711 of the pickup truck roof roll-up push lock 100 of this utility model can effectively offset the impact of vibration on the locking state. On the one hand, the second unlocking mechanism 7 can effectively share the vibration impact force borne by the first unlocking mechanism 6, avoiding wear and deformation of the single locking structure due to long-term concentrated force, and extending the service life of the lock. On the other hand, even if one of the first unlocking mechanism 6 and the second unlocking mechanism 7 becomes slightly loose due to extreme bumps, the other unlocking mechanism can still maintain the fixed state of the sliding part 3, ensuring that the lock head assembly 2 always maintains a stable plug-in engagement with the external parts. This completely eliminates the problem of "accidental opening due to bumps" caused by the existing locks due to insecure locking, providing double security for the goods in the cargo box, and avoiding driving safety hazards caused by accidental opening of the roll-up curtain. Furthermore, the double locking structure 711 of the pickup truck roof roller shutter push-button lock 100 of this utility model can effectively prevent accidental unlocking. A single unlocking action cannot disengage the sliding member 3 from the double restraints. Only after driving the second unlocking mechanism 7 to move and disengage from the sliding member 3, and driving the first unlocking mechanism 6 to rotate and disengage from the seat 1, can the sliding member 3 slide under the action of the first elastic member 5 and drive the lock head assembly 2 to rotate and release the lock through the linkage mechanism 4. Therefore, the pickup truck roof roller shutter push-button lock 100 of this utility model has the characteristics of secure locking and high security.
[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
