Description
Technical Field
[0001] This utility model belongs to the technical field of pickup truck bed covers, and mainly relates to a pickup truck bed flat cover. Background Technology
[0002] Pickup trucks have an open-designed bed that can flexibly load large items such as furniture, building materials, and agricultural machinery. Their load capacity is typically 500-1500 kg (some heavy-duty pickups can reach more than 2 tons), far exceeding that of ordinary cars and SUVs.
[0003] However, goods in an open cargo bed are easily seen or stolen by passersby, especially valuable items (such as tools and equipment). Therefore, users usually add a lid to create a physical barrier, increasing the difficulty of theft and preventing the goods from being damaged (such as spilled liquids or scratches). Furthermore, in rainy weather, goods in an open cargo bed are easily soaked, leading to moisture damage (such as cardboard boxes, timber, and food). A lid creates a sealed space, preventing rainwater from entering.
[0004] Although pickup trucks have added covers to their cargo beds, these covers can still be easily opened by outsiders to retrieve items, posing a continued risk. Furthermore, if the cover loosens and opens due to bumps or airflow while the vehicle is traveling at high speeds, cargo could fall from the cargo bed, causing a traffic accident. Therefore, a device is needed to lock the cover securely and prevent it from opening. Utility Model Content
[0005] This utility model provides a flat cover for the rear bed of a pickup truck to solve the problem that the covers of the rear beds of pickup trucks in the prior art are easily opened.
[0006] To solve the above problems, the present invention adopts the following technical solution:
[0007] A pickup truck bed cover for sealing the rear bed of a pickup truck includes a bracket fixedly mounted on the rear bed of the pickup truck and a top cover hinged to the bracket. A locking mechanism is provided between the top cover and the bracket for locking the top cover and the bracket.
[0008] The locking mechanism includes a torsion member rotatably mounted on the outside of the top cover, a locking body provided on the top cover, and an unlocking member hinged to the locking body. The bracket is provided with a locking hook for locking with the locking body, and the unlocking member is used to release the locking state of the locking hook and the locking body.
[0009] The torsion member is connected to the unlocking member through a transmission. When the torsion member rotates, it drives the unlocking member to rotate, thereby releasing the locking state of the locking hook and the locking body.
[0010] It has the following beneficial effects: The locking body is installed on the top cover, and the locking hook is set on the bracket. The two are locked together by a snap-fit locking mechanism. When the top cover is closed, the locking body and the locking hook are tightly engaged to form a mechanical locking point, making it difficult for external force to open directly.
[0011] Furthermore, a connecting rod is hinged between the torsion member and the unlocking member, and the torsion member and the unlocking member are connected by a transmission through the connecting rod.
[0012] It has the following beneficial effects: the hinged connecting rod allows the torsion member and the unlocking member to move at different angles.
[0013] Furthermore, the connecting rod is a telescopic rod capable of changing its length.
[0014] Furthermore, the locking body includes a mounting base on the top cover and a locking plate and a limiting plate hinged to the mounting base. The locking plate is used to lock with the lock hook, and the limiting plate is used to restrict the rotation of the locking plate to maintain the locking state between the locking plate and the lock hook. The unlocking member is used to press the limiting plate, and the unlocking member rotates to press the limiting plate to make it rotate, so as to release the limitation of the limiting plate on the locking plate.
[0015] It has the following beneficial effects: After the lock plate and the lock hook are locked, the limiting plate forms a lock by blocking the rotation path of the lock plate. Even if the lock plate shakes slightly due to bumps or external forces, the limiting plate can prevent it from rotating and unlocking on its own, thus avoiding accidental unlocking due to vibration.
[0016] Furthermore, the locking plate has a latch, and the limiting plate has a protrusion for engaging with the latch. When the protrusion is located inside the latch, the locking plate engages with the locking hook. The limiting plate has a stopping protrusion for engaging with the unlocking member. The unlocking member rotates to press against the stopping protrusion, thereby driving the limiting plate to rotate and release the engagement between the protrusion and the latch.
[0017] It has the following beneficial effects: the locking plate's bayonet and the limiting plate's protrusion adopt a "groove-boss" fit, and the two form a limit when they come into contact. The fit angle between the protrusion and the bayonet adopts an "acute angle wedge tightening" design. When locking, the locking hook's pulling force will be converted into the pressure of the protrusion wedging into the bayonet (similar to the wedge principle), forming a "tighter the more you pull" self-locking effect.
[0018] Furthermore, the mounting base is provided with a first torsion spring at the hinge of the locking plate and a second torsion spring at the hinge of the limiting plate. The first torsion spring is used to drive the locking plate to rotate, so that the locking plate and the locking hook are in the unlocked state. The second torsion spring is used to drive the limiting plate to rotate, so that the protrusion and the bayonet cooperate to maintain the locking state of the locking plate and the locking hook.
[0019] It has the following beneficial effects: When the limiting plate releases its restriction on the lock plate, the first torsion spring releases its potential energy instantly, driving the lock plate to rotate about 90 degrees, so that the lock plate and the lock hook can be separated quickly, avoiding unlocking difficulties caused by rust or jamming; if the user does not fully open the top cover after unlocking, the continuous torque of the first torsion spring will keep the lock plate slightly open, preventing accidental locking again.
[0020] Furthermore, the lock plate has a locking slot for engaging with a lock hook;
[0021] The locking plate rotates so that the lock opening moves away from the limiting plate. The mounting base has a stop plate, and the lock opening faces the stop plate. The stop plate and the lock opening form a locking space. When the lock hook is located in the locking space, the locking plate and the lock hook are in the locked state.
[0022] It has the following beneficial effects: the thrust when the locking hook enters can drive the locking plate to rotate, realizing the automated process of "locking upon engagement" and reducing manual operation steps. Attached Figure Description

[0032] like Figures 1-3As shown, a pickup truck bed cover is used to seal the rear bed of a pickup truck, thereby protecting the items inside the rear bed. The cover includes a bracket 1 fixedly mounted on the rear bed of the pickup truck and a top cover 2 hinged to the bracket 1. The top cover 2 can be opened from the rear end of the rear bed. A locking mechanism is provided between the top cover 2 and the bracket 1 to lock the top cover 2 and the bracket 1, preventing the top cover 2 from being easily opened.
[0033] In this embodiment, the locking mechanism includes a torsion member 3 rotatably mounted on the outside of the top cover 2, a locking body 4 provided on the top cover 2, and an unlocking member 7 hinged to the locking body 4. The bracket 1 is provided with a locking hook 8 for locking with the locking body 4. The locking body 4 is used to lock with the locking hook 8, and the unlocking member 7 is used to release the locking state of the locking hook 8 and the locking body 4.
[0034] The torsion member 3 is connected to the unlocking member 7 via a transmission. When the torsion member 3 rotates, it drives the unlocking member 7 to rotate, thereby releasing the locking state of the locking hook 8 and the locking body 4.
[0035] In this embodiment, the locking body 4 is installed on the top cover 2, and the bracket 1 is provided with a locking hook 8. The two are locked together by a snap-fit mechanism to fix the top cover 2. When the top cover 2 is closed, the locking body 4 and the locking hook 8 are tightly engaged to form a mechanical locking point, making it difficult for external force to open directly.
[0036] The locking body 4 and the locking hook 8 are located on the inner side of the top cover 2 and the bracket 1, preventing direct external contact with the locking point and avoiding direct damage to the locking structure using tools (such as pry bars). In this embodiment, the locking body 4 and the locking hook 8 are made of high-strength materials (such as metal), further enhancing their resistance to damage.
[0037] In this embodiment, the torsion member 3 (such as a knob) is installed on the outside of the top cover 2, and the unlocking member 7 needs to be driven by rotation. The unlocking member 7 and the torsion member 3 are connected by a rigid transmission (such as a connecting rod or gear) to ensure that unlocking can only be triggered by the correct operation of the torsion member 3, avoiding accidental unlocking by external force.
[0038] The bracket 1 is directly mounted to the rear bed of the pickup truck and secured by bolts or welding to form a stable support base. The top cover 2 is hinged to the bracket 1. When closed, the weight of the top cover 2 and the combined force of the locking mechanism will make the locking point tighter, further resisting external prying forces.
[0039] In this embodiment, the locking mechanism is symmetrically arranged on both sides of the top cover 2 (e.g., a set of locking bodies 4 + locking hooks 8 on each side), forming a "two-point locking", which is more difficult to pry open from one side than a single-point locking. For example, when the top cover 2 is closed, the locking bodies 4 on both sides are simultaneously engaged with the locking hooks 8 of the bracket 1, and the cover can only be opened by breaking the locking points on both sides at the same time.
[0040] During normal unlocking, the user can easily release the lock by operating the outer torsion component 3 (such as a key with a knob), which drives the unlocking component 7 through transmission.
[0041] In this embodiment, a connecting rod 5 is hinged between the torsion member 3 and the unlocking member 7, and the torsion member 3 and the unlocking member 7 are connected by transmission through the connecting rod 5. The connecting rod 5 is adjustable in length and is a telescopic rod to adapt to the complex spatial structure inside the top cover 2.
[0042] The hinged connecting rod 5 is a "linkage mechanism" (similar to a crank-rocker structure), allowing the torsion member 3 and the unlocking member 7 to move at different angles. For example, the torsion member 3 is mounted on the outer surface of the top cover 2 (such as a horizontal knob), while the unlocking member 7 needs to rotate in the vertical direction to contact the locking body 4. The connecting rod 5 can convert the horizontal rotation into vertical rotation through the hinge point, adapting to complex layouts.
[0043] In this embodiment, the connecting rod 5 is an independent component and can be disassembled and installed. During maintenance, the damaged connecting rod 5 can be replaced separately without disassembling the entire locking mechanism.
[0044] In this embodiment, as Figures 3-5 As shown, the locking body 4 includes a mounting base 6 on the top cover 2, a locking plate 9 and a limiting plate 10 hinged to the mounting base 6, and an unlocking member 7 hinged to the mounting base 6. The locking plate 9 is used to lock with the locking hook 8, the limiting plate 10 is used to restrict the rotation of the locking plate 9 to maintain the locking state between the locking plate 9 and the locking hook 8, and the unlocking member 7 is used to press against the limiting plate 10. When the unlocking member 7 rotates, it presses against the limiting plate 10 to make it rotate, thereby releasing the limitation of the limiting plate 10 on the locking plate 9, allowing the locking plate 9 to rotate, and thus the locking plate 9 is no longer locked with the locking hook 8.
[0045] In this embodiment, after the locking plate 9 and the locking hook 8 are locked, the limiting plate 10 forms a lock by blocking the rotation path of the locking plate 9. Even if the locking plate 9 shakes slightly due to bumps or external forces, the limiting plate 10 can prevent it from rotating and unlocking on its own, avoiding accidental unlocking due to vibration.
[0046] In the locked state, the pulling force of the hook 8 is transmitted to the limiting plate 10 through the locking plate 9, and both share the external force. The locking plate 9 is responsible for engaging with the hook 8, and the limiting plate 10 is responsible for restricting the rotation of the locking plate 9, forming a "force closed loop". For example, when an external force pries the hook 8, the force acts simultaneously on the hinge point of the locking plate 9 and the limiting plate 10, and both must be destroyed simultaneously to unlock the device.
[0047] The unlocking element 7 can only be rotated by pressing against the limiting plate 10 (e.g., clockwise), while the limiting plate 10 restricts the locking plate 9 in a one-way manner (e.g., only restricting the locking plate 9 to rotate counterclockwise). This design ensures that during normal driving, the limiting plate 10 always holds the locking plate 9 (without requiring additional power), preventing accidental unlocking. Unlocking requires the torsion element 3 to actively press against the limiting plate 10.
[0048] In this embodiment, the limiting piece 10 is hidden inside the mounting base 6 and cannot be directly accessed from the outside. Even if an unauthorized unlocker damages the torsion member 3 (such as breaking the knob), they cannot directly operate the limiting piece 10, and the locking piece 9 remains locked by the limiting piece 10.
[0049] In this embodiment, the hinge point between the limiting piece 10 and the locking piece 9 uses a high-strength pin, and the hinge gap is extremely small.
[0050] In this embodiment, as Figures 4-7 As shown, the locking plate 9 has a latch 16, and the limiting plate 10 has a protrusion 15 for engaging with the latch 16. When the protrusion 15 is located within the latch 16, the limiting plate 10 restricts the rotation of the locking plate 9, thereby locking the locking plate 9 with the locking hook 8. The limiting plate 10 has a stop protrusion 14 for engaging with the unlocking member 7. The unlocking member 7 rotates to press against the stop protrusion 14, thereby driving the limiting plate 10 to rotate, releasing the engagement between the protrusion 15 and the latch 16. At this time, the limiting plate 10 no longer restricts the rotation of the locking plate 9, thereby allowing the locking hook 8 to disengage from the locking plate 9.
[0051] In this embodiment, the locking plate 9's latch 16 and the limiting plate 10's protrusion 15 are engaged in a "groove-boss" configuration, forming a limiting effect when they contact each other. The engagement angle between the protrusion 15 and the latch 16 adopts an "acute angle wedge tightening" design (e.g., the angle of the protrusion 15's slope is ≤15°). When locked, the pulling force of the locking hook 8 is converted into pressure from the protrusion 15 wedging into the latch 16 (similar to the wedge principle), creating a self-locking effect that "tightens as it is pulled".
[0052] In this embodiment, the stop protrusion 14 of the limiting piece 10 contacts the unlocking member 7. When unlocking, the unlocking member 7 rotates, pushing the stop protrusion 14, causing the limiting piece 10 to rotate around the hinge axis.
[0053] In this embodiment, the contact surface between the bayonet 16 and the protrusion 15 is hardened (hardness ≥ HRC50) and a rounded transition (R ≥ 2 mm) is provided. The rounded transition reduces stress concentration and avoids metal fatigue cracks caused by long-term vibration.
[0054] In this embodiment, a first torsion spring 12 is fitted onto the hinge of the locking plate 9 on the mounting base 6, and a second torsion spring 13 is fitted onto the hinge of the limiting plate 10. The first torsion spring 12 is used to drive the locking plate 9 to rotate, so that the locking plate 9 and the locking hook 8 are in the unlocked state, that is, the first torsion spring 12 makes the locking plate 9 have a tendency to rotate and unlock. The second torsion spring 13 is used to drive the limiting plate 10 to rotate, so that the protrusion 15 and the bayonet 16 cooperate to maintain the locking state of the locking plate 9 and the locking hook 8, that is, the second torsion spring 13 has a tendency to make the limiting plate 10 continuously restrict the rotation of the locking plate 9 and maintain the locking state of the locking plate 9 and the locking hook 8.
[0055] The first torsion spring 12 at the hinge of the locking plate 9 always maintains a counterclockwise torque on the locking plate 9. When the limiting plate 10 releases its restraint on the locking plate 9, the first torsion spring 12 instantly releases its potential energy, driving the locking plate 9 to rotate approximately 90 degrees, causing the locking plate 9 to quickly separate from the locking hook 8, avoiding unlocking difficulties caused by rust or jamming. If the user does not fully open the top cover 2 after unlocking, the continuous torque of the first torsion spring 12 will keep the locking plate 9 slightly open, preventing accidental locking again.
[0056] The second torsion spring 13 at the hinge of the limiting plate 10 continuously pushes the limiting plate 10 with clockwise torque. When the vehicle's vibration causes the locking hook 8 to slightly shift, the second torsion spring 13 will simultaneously push the limiting plate 10, ensuring that the protrusion 15 always presses firmly against the latch 16. When the top cover 2 is closed, the locking hook 8 pushes the locking plate 9 to rotate and compress the first torsion spring 12. At the same time, the limiting plate 10 automatically engages with the latch 16 under the action of the second torsion spring 13, eliminating the need for manual engagement of the limiting plate 10 and achieving automatic "locking upon closing the cover".
[0057] In this embodiment, the locking plate 9 has a locking opening 17, which is used to cooperate with the locking hook 8. When the top cover 2 is fastened to the bracket 1, the locking hook 8 will enter the locking opening 17, and the locking hook 8 will push against the locking plate 9 to make it rotate, so that the position of the locking opening 17 is away from the limiting piece 10. At this time, the locking plate 9 and the mounting base 6 simultaneously restrict the locking hook 8, and the protrusion 15 will be located in the latch 16. The limiting piece 10 restricts the rotation of the locking plate 9. In this embodiment, the mounting base 6 has a baffle 11, and the locking plate 9 is located between the baffle 11 and the limiting piece 10. In the locked state, the locking opening 17 is directly opposite the baffle 11, and the baffle 11 and the locking opening 17 form a locking space. The locking hook 8 is located in the locking space. The baffle 11 and the locking plate 9 together restrict the locking hook 8 to prevent it from falling out of the locking space, and the locking plate 9 and the locking hook 8 are in the locked state at this time.
[0058] The locking slot 17 on the locking plate 9 is a key structure that directly engages with the locking hook 8. When the top cover 2 is closed, the locking hook 8 slides in along the edge of the locking slot 17, and through physical contact, pushes the locking plate 9 to rotate, causing the locking slot 17 to move away from the limiting plate 10, thus creating conditions for the subsequent locking of the limiting plate 10. The shape of the locking slot 17 guides the locking hook 8 to enter smoothly without the need for precise alignment, improving the convenience of locking. At the same time, the thrust of the locking hook 8 when it enters can drive the locking plate 9 to rotate, realizing an automated process of "locking upon locking" and reducing manual operation steps.
[0059] The baffle 11 on the mounting base 6 cooperates with the locking plate 9 to form a closed locking space of "baffle 11-locking port 17" when locked. The locking hook 8 is confined within this space, and its movement is blocked by the baffle 11 and the locking plate 9. When the locking hook 8 is located within the locking space, the baffle 11 and the locking plate 9 block its movement, forming a "two-way clamping" effect to prevent the locking hook 8 from coming out.
[0060] When locked, the rotation range of the locking plate 9 is limited by the baffle plate 11 and the limiting plate 10, ensuring that it is in a fixed position when locked and preventing displacement due to vibration or other factors. The baffle plate 11 provides a physical limit for the locking plate 9, preventing the locking plate 9 from rotating accidentally due to external forces such as bumps when it is not unlocked, and preventing the locking hook 8 from disengaging from the locking plate 9; the limiting plate 10 further locks the locking plate 9 through the cooperation of the protrusion 15 and the latch 16, forming a "double limit".
[0061] The force on the locking hook 8 is transmitted to the baffle 11 and the limiting plate 10 through the locking plate 9, which disperses the load, reduces stress concentration in a single component, and lowers the risk of structural damage.
[0062] The working process of this utility model is as follows:
[0063] When it is necessary to open the top cover 2, the user turns the torsion member 3, which drives the unlocking member 7 to rotate. The unlocking member 7 pushes the limit plate 10 to rotate, so that it no longer restricts the rotation of the lock plate 9. The lock plate 9 rotates, causing the lock hook 8 to separate from the lock mouth 17, thereby completing the unlocking of the top cover 2.
[0064] When the top cover 2 needs to be closed, the user simply pulls down the top cover 2 and fastens it onto the bracket 1. The locking hook 8 will press against the locking opening 17, causing the locking opening 17 to move away from the position of the limiting piece 10 under the rotation of the locking piece 9. At the same time, during the rotation of the locking piece 9, it will push the limiting piece 10 to rotate until the protrusion 15 rotates into the slot 16, forming the limiting piece 10 restricting the locking piece 9, thereby completing the locking.
