Description

Technical Field

[0001] This invention relates to the field of vehicle accessories technology, specifically a manual switching structure for the rear cargo cover of an electric pickup truck. Background Technology

[0002] The electric rear cargo cover for pickup trucks is an essential product for pickup trucks used as a means of suburban travel. It is installed on the rear cargo bed of the pickup truck, forming an independent and enclosed storage space with the cargo bed. The existing product types can be roughly divided into the following categories: (1) Manually rolled plastic cover cloth, which uses the frame structure of the cargo bed and processes the selvage on the cloth to form a manually rolled-up and locked structure cargo bed cover. However, this type of plastic is easily damaged and ages easily; (2) Using a hard board structure and a hinge structure to achieve folding cover, which is prone to water leakage and is inconvenient for adults to operate; (3) Manual push-pull telescopic structure, which is inconvenient to operate and has average anti-theft performance; (4) Conventional electric telescopic structure, which uses a motor to drive the roller shutter to slide on the track to achieve the opening and closing function. However, it is easily obstructed by external dirt, and the motor and controller are prone to failure. Moreover, if the motor and controller fail, or if the power supply of the whole vehicle is abnormal, the product will not be able to open and close normally and will lose its function. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a manual switching structure for the rear cargo cover of an electric pickup truck, in light of the current state of the technology.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1 to 4 As shown, the present invention discloses a manual switching structure for the rear cargo cover of an electric pickup truck, used to switch the rear cargo cover 1 of the pickup truck between electric mode and manual mode, thereby enabling the rear cargo cover 1 to be opened manually. The structure includes: a drive component 2, disposed within the cargo compartment, with a snap-fit ​​sleeve 3 connected to the output end of the drive component 2; a connecting sleeve 4, on which a transmission component is disposed, and a driven component 5 is provided at the bottom end of the rear cargo cover 1, the transmission component driving the rear cargo cover 1 to move via the driven component 5; a connecting component 6, snapped between the snap-fit ​​sleeve 3 and the connecting sleeve 4, the connecting component 6 transmitting the rotation of the snap-fit ​​sleeve 3 to the connecting sleeve 4; and a traction assembly, disposed within the cargo compartment, one end of the traction assembly connected to the connecting component 6, the traction assembly driving the connecting component 6 to snap or disengage from the snap-fit ​​sleeve 3.

[0031] Based on the above embodiments, the technical problem to be solved by this application is how to achieve the switching between electric and manual modes of the rear cargo cover 1 relative to the rear cargo compartment. To this end, this application provides a drive component 2 inside the rear cargo compartment, with a snap-fit ​​sleeve 3 connected to the output end of the drive component 2. Preferably, a motor can be selected as the drive component 2. A connecting sleeve 4 is provided, with a transmission component on the connecting sleeve 4. A driven component 5 is provided at the bottom end of the rear cargo cover 1. A connecting component 6 is used to connect the drive component 2 and the connecting sleeve 4, and a traction component is used to pull the connecting component 6 away from or towards the snap-fit ​​sleeve 3. During operation, both ends of the connecting component 6 are snapped between the snap-fit ​​sleeve 3 and the connecting sleeve 4, thereby transmitting the rotation of the snap-fit ​​sleeve 3 driven by the motor to the transmission component on the connecting component 6. The transmission component then drives the rear cargo cover 1 to move relative to the rear cargo compartment through the driven component 5, thus realizing the electric mode of movement of the rear cargo cover 1. When external factors cause the motor to malfunction, the connecting component 6 and the snap-fit ​​sleeve 3 can be disengaged by pulling the traction component. At this time, without external resistance, the rear cargo cover can be moved manually. This allows for the switching between electric and manual modes of the rear cargo cover 1 relative to the rear cargo compartment. Installing the towing device inside the cargo compartment provides excellent anti-theft protection. When switching the rear cargo cover 1 to manual mode, the side cover of the rear cargo compartment can be opened first, and then the towing device can be pulled.

[0032] Furthermore, the traction assembly includes: a pulling block 7, which abuts against one end of the connector 6 near the snap sleeve 3; a traction rope 8, one end of which passes through the connector 6 and is fixed to the pulling block 7; a limiting plate 9, which is detachably connected to the end of the connector sleeve 4 and sleeved on the outside of the traction rope 8; and an elastic member 10, the two ends of which abut against the ends of the limiting plate 9 and the connector 6, respectively.

[0033] Based on the above embodiments, the technical problem to be solved by this application is how the traction assembly drives the connector 6 to engage and disengage with the locking sleeve 3. To this end, the traction assembly of this application includes: a pulling block 7, a traction rope 8, a limiting plate 9, and an elastic element 10. Specifically, the pulling block 7 abuts against the end of the connector 6, one end of the traction rope 8 passes through the connector 6 and is fixed to the pulling block 7, the limiting plate 9 is detachably connected to the end of the connecting sleeve 4 and sleeved on the outside of the traction rope 8, and both ends of the elastic element 10 abut against the limiting plate 9 and the end of the connector 6, respectively. During operation, pulling the traction rope 8 outwards disengages the connector 6 from the locking sleeve 3. When the traction rope 8 is pulled to move the connector 6, the end of the connector 6 presses against the elastic element 10, causing the elastic element 10 to undergo elastic deformation. After releasing the pull on the traction rope 8, the elastic element 10 returns to its extended state, driving the connector 6 to its initial position to engage with the locking sleeve 3. This allows the traction assembly to engage and disengage between the connecting piece 6 and the locking sleeve 3. Preferably, the traction rope 8 can be a steel wire rope, and the elastic element 10 can be a spring or a rubber product.

[0034] Furthermore, the traction assembly also includes: a fixing frame 11, which is disposed inside the carriage; a pull handle 12, which is movably inserted into the fixing frame 11; and two detachably connected adjusting plates 13, one end of which is connected to the pull handle 12, and the other end of the two adjusting plates 13 is connected to the traction rope 8.

[0035] Based on the above embodiments, the technical problem to be solved by this application is how to fix the traction component and the carriage and how to adjust the tension of the traction rope 8. To this end, this application provides a fixing frame 11 inside the carriage, and a pull handle 12 is movably inserted into the fixing frame 11. One end of the pull handle 12 is connected to two adjusting plates 13, and one end of the traction rope 8 is connected to the adjusting plate 13. The fixing frame 11 achieves the fixation between the traction component and the rear carriage. Since the two adjusting plates 13 are respectively connected to the pull handle 12 and the traction rope 8, the tension of the traction rope 8 can be adjusted by adjusting the distance between the two adjusting plates 13. Preferably, the detachable connection between the two adjusting plates 13 can be achieved by bolt connection, that is, a threaded hole is provided on one adjusting plate 13, and a bolt through hole is provided on the other adjusting plate 13. One end of the bolt passes through the bolt through hole and is connected to the threaded hole. Adjusting the depth to which the bolt is screwed into the threaded hole achieves the purpose of adjusting the distance between the two adjusting plates 13. The fixing between the adjusting clamp 13, the traction rope 8, and the pull handle 12 can be achieved by welding, knotting, or other connection methods.

[0036] Furthermore, the output end of the drive unit 2 is connected to a locking block 14, which is locked onto the inner wall of the locking sleeve 3.

[0037] Based on the above embodiments, the technical problem to be solved by this application is how to make the driving component 2 drive the snap-fit ​​sleeve 3 to rotate. To this end, this application provides a snap-fit ​​block 14 at the output end of the driving component 2, and snaps the snap-fit ​​block 14 onto the inner side wall of the snap-fit ​​sleeve 3. In this way, the driving component 2 can drive the snap-fit ​​sleeve 3 to rotate through the snap-fit ​​block 14.

[0038] Furthermore, the transmission component includes a drive gear 15 disposed on the outer circle of the connecting sleeve 4, and a driven gear 16 connected to one end of the connecting sleeve 4, the driven gear 16 meshing with the driven component 5.

[0039] Based on the above embodiments, the technical problem to be solved by this application is how the transmission component drives the rear cargo cover 1 to move. To this end, this application provides a drive gear 15 and a driven gear 16 on the outer circumference and end of the connecting sleeve 4, respectively, with the driven gear 16 meshing with the driven component 5. When the drive component 2 drives the connecting sleeve 4 to rotate, the drive gear 15 on the outer circumference of the connecting sleeve 4 also begins to rotate. The rotation of the drive gear 15 drives the driven gear 16 to rotate, thereby moving the rear cargo cover 1. This achieves the goal of the transmission component driving the movement of the rear cargo cover 1.

[0040] Furthermore, the drive unit 2 is provided with a screw cap 17, the screw cap 17 has a storage space 18 formed inside it, and a spiral track 19 is provided in the storage space 18, and the rear compartment cover 1 is slidably disposed in the spiral track 19.

[0041] Based on the above embodiments, the technical problem to be solved by this application is how the rear cargo cover 1 is folded back when the rear cargo compartment is opened by moving the rear cargo cover 1. To this end, this application provides a screw cap 17 on the driving member 2. The screw cap 17 forms a storage space 18 and a spiral track 19 disposed within the storage space 18, and the rear cargo cover 1 is slidably disposed within the spiral track 19. When the driving member 2 moves the rear cargo cover 1, one end of the rear cargo cover 1 is inserted into the storage space 18 and moves along the spiral track 19, folding it. This achieves the folding back of the rear cargo cover 1.

[0042] Furthermore, the rear compartment is equipped with guide rails 20, and the two sides of the rear compartment cover 1 are movably mounted within the guide rails 20.

[0043] Based on the above embodiments, the technical problem to be solved by this application is how to ensure the correctness of the movement direction of the rear cargo cover 1 when the driving component 2 drives the rear cargo cover 1 to move. To this end, this application provides a guide rail 20 on the rear cargo compartment, and movably positions both sides of the rear cargo cover 1 within the guide rail 20. When the driving component 2 drives the rear cargo cover 1 to move, both sides of the rear cargo cover 1 slide within the guide rail 20. This ensures the correctness of the movement direction of the rear cargo cover 1.

[0044] Furthermore, the drive component 2 is connected to a housing 21 on one side, and a number of bearings 22 are connected to the outer wall of the connecting sleeve 4, with the outer wall of each bearing 22 abutting against the inner wall of the housing 21.

[0045] Based on the above embodiments, the technical problem to be solved by this application is how to restrict the degree of freedom of the connecting sleeve 4 in the radial direction. To this end, this application provides a housing 21 on one side of the driving member 2, and a plurality of bearings 22 are provided on the outer side of the connecting sleeve 4, with the outer walls of the bearings 22 abutting against the inner wall of the housing 21. When the driving member 2 drives the connecting sleeve 4 to rotate, the connecting sleeve 4 is rotatably connected to the housing 21 under the action of the bearings 22, thus restricting the degree of freedom of the connecting sleeve 4 in the radial direction. Preferably, to prevent interference between the driving gear 15 and the inner wall of the housing 21, bearings 22 with a diameter larger than the outer diameter of the driving gear 15 can be selected and fitted onto the outer wall of the connecting sleeve 4, or a clearance groove can be provided inside the housing 21.
