DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model will be further described in detail below by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0027] A jacking assembly for a roof tent, comprising a bottom slide rail 11, a bottom slide block 12, a top slide rail 13, a top slide block 14, a locking block 15, a main connecting rod 16, a side rod 17 and an actuator 18, the locking block 15 and the bottom slide block 12 are arranged on the bottom slide rail 11, the locking block 15 is provided with a guide groove 151 and a locking groove 152, the locking groove 152 is an open groove towards one end, which is arranged at one end of the locking block 15; the guide groove 151 is a long strip-shaped through hole. The top slide block 14 is slidingly arranged on the top slide rail 13, the two ends of the main connecting rod 16 are connected with the top slide block 12 and the bottom slide block 14 respectively; the two ends of the side rod 17 are connected with the main connecting rod 16 and the locking block 15 respectively, and the side rod 17 is slidingly connected with the guide groove 151; the actuator 18 is arranged on the bottom slide rail 11, and the output end thereof is connected with the bottom slide block 11, so that the bottom slide block 12 is driven to reciprocate along the bottom slide rail 11 by the actuator 18. The locking rod 161 is arranged on the main connecting rod 16, and when the jacking assembly is in a retracted state, the locking rod 161 is arranged in the locking groove 152. The actuator 18 includes but is not limited to an electric cylinder, an oil cylinder and an air cylinder.

[0028] In an embodiment, as shown in Figures 1-8 One end of the side rod 17 is provided with a mounting pin shaft 172, which is mounted in the guide groove 151, so that the lower support point of the side rod 17 can be adjusted horizontally. In order to reduce the friction between the pin shaft 172 and the guide groove 151, a roller is rotatably arranged on the pin shaft 172, and the roller is arranged concentrically with the pin shaft 172.

[0029] In an embodiment, as shown in Figures 1-8As shown, the jacking assembly further comprises a buffer block 111 arranged on the bottom slide rail 11. The buffer block 111 is fixed on the bottom slide rail 11 by bolts. During the retraction of the jacking assembly, the buffer block 111 plays a limiting role, avoiding the impact of the locking rod 161 on the locking block 15. In addition, the buffer block 111 is made of plastic or rubber, reducing the noise generated by the impact.

[0030] In an embodiment, as shown in Figures 1-8 The jacking assembly further comprises a lock catch 19 arranged on the roof. When the jacking assembly is in the retracted state, the lock catch 19 hooks the main connecting rod 16. The lock catch 19 is locked with one end of the main connecting rod 16, and the main connecting rod 15 is locked with the locking block 15, which cooperates to achieve stable locking of the jacking assembly without the need for additional locking mechanisms. The structure is compact, effectively ensuring that the jacking assembly does not accidentally expand during vehicle travel. Moreover, by hooking the roof through the main connecting rod 16 and the lock catch 19, the roof is prevented from shaking during vehicle travel.

[0031] In an embodiment, as shown in Figures 1-8 The main connecting rod 16 is provided with a cladding 162, which is in contact with the lock catch 19. The cladding 162 is installed at the end of the main connecting rod 16 where the lock catch 19 is locked. Typically, the cladding 162 is made of plastic, effectively reducing noise generation, while avoiding repeated contact between the lock catch 19 and the main connecting rod 16, which can cause surface wear.

[0032] In an embodiment, as shown in Figures 1-8 The main connecting rod 16 is provided with a first buffer pad 163. When the jacking assembly is in the retracted state, the first buffer pad 163 is located between the top slide rail 13 and the main connecting rod 16, also serving as a limiting role, so that the main connecting rod 16 does not come into contact with the top slide rail 13, avoiding collision. In addition, the main connecting rod 16 and the top slide rail 13 are hingedly connected, so the first buffer pad 163 is sandwiched in the middle, preventing the jacking assembly from continuing to retract and effectively avoiding collision between the main connecting rod 16 and the side rod 17.

[0033] In an embodiment, as shown in Figures 1-8 The side wall of the side rod 17 is provided with a protrusion 171. When the jacking assembly is in the retracted state, the side rod 17 is partially housed in the main connecting rod 16. Typically, the side rod 17 and the main connecting rod 16 have a clearance fit, but due to processing errors, subsequent assembly and normal wear and tear, the side rod 17 may come into contact with the inner wall of the main connecting rod 16, causing noise and wear. By providing the protrusion 171, the side rod 17 is centrally positioned, so that even if the side rod 17 comes into contact with the inner wall of the main connecting rod 16, only the protrusion 171 comes into contact with the inner wall, and most of the side rod 17 does not come into contact with the main connecting rod 16.

[0034] In an embodiment, as shown in Figures 1-8 The bottom slide rail 11 is provided with a sliding part 112, and the sliding part 112 has a T-shaped cross section.

[0035] In the preferred embodiment, as shown in Figures 1-8 The sliding groove 121 is provided with a bushing 122, and the middle of the sliding groove 121 is concave to form a positioning groove, and the bushing 122 is provided with a positioning part 1221 which is convex at a corresponding position and matches the positioning groove. Two bushings 122 are arranged in each bottom slide block 12 and are arranged on both sides of the sliding groove 121. When the bottom slide block 12 is connected with the bottom slide rail 11 through the bushing 122, the bushing 122 is quickly and reliably assembled with the bottom slide block 12 due to the arrangement of the positioning part 1221. The bushing 122 is usually made of plastic, which can avoid the wear of the guide rail and reduce the generation of abnormal sound.

[0036] In use, the bottom guide rail 11 and the lower support 22 are fixed to the top of the vehicle, and the top slide rail 12 and the upper support 21 are fixed to the roof of the vehicle. When unfolding, the actuator 18 drives the bottom slide block 12 to move leftward, and the lock rod 161 and the pin shaft move rightward synchronously. When the pin shaft is supported at the left end of the guide groove 151, the lock rod 161 is unlocked from the locking groove 1152. The bottom slide block 12 is continuously pushed to move leftward, and the main connecting rod 16 and the side rod 17 are matched with each other, so that the roof of the vehicle is pushed upward by the main connecting rod 16. Since the main connecting rod 16 is hinged to the top slide block 14 and is connected with the top slide rail 13 through the top slide block 14, the support position of the main connecting rod 16 to the roof of the vehicle can be adaptively adjusted. When unfolding, the roof tent has a wedge-shaped structure and has a certain height space at one end. The folding process is as follows. Since the roof has a certain mass and is loaded on the main connecting rod 16 and the side rod 17, the lower end of the side rod 17 is always supported at the left end of the guide groove 151. The actuator 18 moves reversely to drive the bottom slide block 14 to move rightward, and the main connecting rod 16 and the side rod 17 are folded downward. When completely folded, the actuator 18 continues to pull the bottom slide block 14 to move rightward, the pin shaft and the lock rod 161 move rightward synchronously, the lock rod 161 is inserted into the locking groove 152, and one end of the main connecting rod 16 is inserted into the lock, so that the roof lifting assembly is completely locked. During driving, the roof does not shake and is not unlocked accidentally, and the reliability is high.

[0037] The above is only a preferred embodiment of the utility model, and is not used to limit the implementation range of the utility model. If the utility model is modified or replaced equivalently without departing from the spirit and range of the utility model, it should be covered in the protection range of the utility model claim.
