DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] A lifting device for a roof tent, such as Figure 1 As shown, it includes a lifting component 1 and a guide component 2, and the lifting component 1 and the guide component 3 are arranged on the side of the vehicle, and the lifting component 1 and the guide component 3 connect the vehicle and the roof; usually, two lifting components 1 are arranged, and two guide components 2 are arranged, and the roof is lifted up by the two lifting components 1 and the guide components 2.

[0041] like Figure 2-Figure 9As shown, the lifting assembly 1 includes a bottom slide rail 11, a bottom slider 12, a top slide rail 13, a top slider 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 slider 12 are arranged on the bottom slide rail 11. A guide groove 151 and a locking groove 152 are arranged on the locking block 15. The locking groove 152 is an open groove toward one end, which is arranged at one end of the locking block 15; the guide groove 151 is a long strip through hole. The top slider 14 is slidably arranged on the top slide rail 13, and the two ends of the main connecting rod 16 are respectively connected to the top slider 12 and the bottom slider 14; the two ends of the side rod 17 are respectively connected to the main connecting rod 16 and the locking fixed block 15, and the side rod 17 is slidably connected to the guide groove 151; the actuator 18 is arranged on the bottom slide rail 11, and its output end is connected to the bottom slider 11, and then the bottom slider 12 is driven to reciprocate along the bottom slide rail 11 through the actuator 18. A locking rod 161 is arranged on the main connecting rod 16, and when the jacking assembly 1 is in a retracted state, the locking rod 161 is placed in the locking groove 152. Among them, the actuator 18 includes but is not limited to an electric cylinder, an oil cylinder, and a pneumatic cylinder.

[0042] In one embodiment, if Figure 2-Figure 9 As shown, a mounting pin 172 is arranged at one end of the side bar 17, and the pin 172 is installed in the guide groove 151, so that the lower support point of the side bar 17 can be adjusted horizontally. In order to reduce the friction between the pin 172 and the guide groove 151, a roller is rotatably arranged on the pin 172, and the roller and the pin 172 are arranged concentrically.

[0043] In one embodiment, if Figure 2-Figure 9 As shown, the lifting assembly 1 further includes a buffer block 111, which is arranged on the bottom slide rail 11. The buffer block 111 is fixed to the bottom slide rail 11 by bolts. During the retraction process of the lifting assembly 1, the buffer block 111 is arranged to play a limiting role to prevent the locking rod 161 from hitting the locking fixed block 15. In addition, the buffer block 111 is a plastic part or a rubber part to reduce the noise generated by the collision.

[0044] In one embodiment, if Figure 2-Figure 9 As shown, the lifting assembly 1 also includes a lock 19, which is arranged on the roof. When the lifting assembly 1 is in a retracted state, the lock 19 hooks the main connecting rod 16. The lock 19 is locked with one end of the main connecting rod 16, and the main connecting rod 15 is locked with the locking fixing block 15, so as to realize the stable locking of the lifting assembly 1, without the need to set up an additional locking mechanism, and the structure is compact, which effectively ensures that the lifting assembly 1 is not accidentally deployed during the driving of the vehicle. And the main connecting rod 16 is hooked on the roof through the lock 19 to prevent the roof from shaking during the driving of the vehicle.

[0045] In one embodiment, if Figure 2-Figure 9As shown, a covering member 162 is provided on the main connecting rod 16, and the covering member 162 contacts the lock buckle 19. The covering member 162 is installed at one end of the main connecting rod 16 locked with the lock buckle 19; usually, the covering member 162 is a plastic member, which effectively reduces the generation of noise and prevents the lock buckle 19 from repeatedly contacting the main connecting rod 16 to cause surface wear.

[0046] In one embodiment, if Figure 2-Figure 9 As shown, a first buffer pad 163 is provided on the main connecting rod 16. When the jacking assembly 1 is in the retracted state, the first buffer pad 163 is located between the top slide rail 13 and the main connecting rod 16, and also plays a limiting role, so that the main connecting rod 16 and the top slide rail 13 do not contact each other, thereby avoiding collision; in addition, the main connecting rod 16 and the top slide rail 13 are hinged structures, so the first buffer pad 163 is sandwiched in the middle, so that the jacking assembly 1 cannot continue to retract, effectively avoiding collision between the main connecting rod 16 and the side rod 17.

[0047] In one embodiment, if Figure 2-Figure 9 As shown, the side wall of the side bar 17 is provided with a protrusion 171. When the lifting assembly 1 is in the retracted state, part of the side bar 17 is received in the main connecting rod 16. Usually, there is a clearance fit between the side bar 17 and the receiving groove of the main connecting rod 16. However, due to processing errors, subsequent assembly and normal wear and tear, there is contact and friction between the side bar 17 and the inner wall of the receiving groove of the main connecting rod 16, causing abnormal noise and wear. By providing the protrusion 171, the side bar 17 is centrally positioned. Even if the side bar 17 contacts the inner wall of the receiving groove of the main connecting rod 16, only the protrusion 171 contacts the inner wall of the receiving groove, and most of the side 17 will not contact the main connecting rod 16.

[0048] In one embodiment, if Figure 2-Figure 9 As shown, a sliding portion 112 is provided on the bottom slide rail 11 , and the cross section of the sliding portion 112 is “T”-shaped. A through sliding groove 121 cooperating with the sliding portion is provided on the bottom slide block 12 .

[0049] In the above preferred embodiment, Figure 2-Figure 9 As shown, a bushing 122 is arranged in the slide groove 121, a positioning groove is recessed in the middle of the slide groove 121, and a positioning portion 1221 cooperating with the positioning groove is convexly arranged at a corresponding position on the bushing 122. Two bushings 122 are arranged in each bottom slider 12, respectively arranged on both sides of the slide groove 121. When the bottom slider 12 is slidably connected with the bottom slide rail 11 through the bushing 122, the positioning portion 1221 ensures that the bushing 122 and the bottom slider 12 are assembled quickly and reliably. The bushing 122 is usually made of plastic, which can avoid wear of the guide rail and reduce the generation of abnormal noise.

[0050] In one embodiment, if Figure 10-12As shown, the guide assembly 2 includes an upper bracket 21, a lower bracket 22, an upper connecting rod 23, a lower connecting rod 24, an outer fork arm 25 and an inner fork arm 26. The upper bracket 21 and the lower bracket 22 connect the roof and the vehicle, and the outer fork arm 25 is hinged with the inner fork arm 26 to form an X structure. The lower end of the outer fork arm 25 is hinged with the lower bracket 22, the upper end of the inner fork arm 26 is hinged with the upper bracket 21, the two ends of the upper connecting rod 23 are respectively hinged with the upper bracket 21 and the upper end of the outer fork arm 25, and the two ends of the lower connecting rod 24 are respectively hinged with the lower bracket 22 and the lower end of the inner fork arm 26. Through the above structure, when the guide assembly 2 is unfolded, the upper bracket 21 and the lower bracket 22 form an angle structure, and the upper bracket 21 moves upward synchronously.

[0051] In one embodiment, if Figure 10-12 As shown, the outer fork arm 25 includes two symmetrically arranged first side plates 251, and the two first side plates 251 are connected and fixed by a first connecting portion 252 and a second connecting portion 253. A downward accommodating groove is formed between the two first side plates 251 and the first connecting portion 252, and an upwardly open accommodating groove is formed between the two first side plates 251 and the second connecting portion 253. When the guide assembly 2 is folded, the inner fork arm 26 is accommodated in the upper and lower accommodating grooves, thereby making the structure compact and improving space utilization. At the same time, the strength of the outer fork arm 25 is improved by the arrangement of the first connecting portion 252 and the second connecting portion 253.

[0052] In one embodiment, if Figure 10-12 As shown, the second buffer pad 254 is arranged on the outer fork arm 25. When the guide assembly 2 is in the contracted state, the second buffer pad 254 contacts with the vehicle roof to play a role of limiting, and prevents the outer fork arm 25 from contacting with the upper bracket 21 at the same time.

[0053] In one embodiment, if Figure 10-12 As shown, the lower connecting rod 24 includes two symmetrically arranged second side plates 241, and a third connecting portion 242 is arranged between the two second side plates 241. The third connecting portion 242 is provided to improve the strength of the lower connecting rod 24; at the same time, the third connecting portion 242 cooperates with the lower bracket 22 to limit the rotation angle of the lower connecting rod 24, thereby preventing the lower connecting rod 24 from rotating excessively when retracting and the inner fork arm 26 from being stuck in the reverse direction when expanding again.

[0054] In one embodiment, if Figure 10-12 As shown, the surface of the inner fork arm 26 is concavely provided with a clearance groove 261. The upper bracket is fixed to the roof by screws and other components, so it is inevitable that there will be some protrusions, and the hinge of the upper bracket 21 of the inner fork arm 26 is the closest place, and the clearance groove 261 is provided to accommodate the installation screws.

[0055] When the present invention is used, Figure 1-Figure 12As shown, the lifting assembly 1 and the guide assembly 2 are arranged on one side of the top of the vehicle, the bottom guide rail 11 and the lower bracket 22 are fixed to the top of the vehicle, the top slide rail 12 and the upper bracket 21 are fixed to the roof, and the roof is controlled to be unfolded obliquely by the lifting assembly 1 and the guide assembly 2. Specifically, the actuator 18 drives the bottom slider 12 to move to the left, and the locking rod 161 and the pin shaft move to the right synchronously. When the pin shaft is supported at the left end of the guide groove 151, the locking rod 161 and the locking groove 1152 are unlocked; the bottom slider 12 is continued to move to the left, and the main connecting rod 16 and the side rod 17 cooperate with each other, and the roof is pushed upward by the main connecting rod 16; at the same time, the guide assembly is synchronously unfolded obliquely upward. Because the main connecting rod 16 is hinged with the top slider 14, and the top slider 14 is slidably connected with the top slide rail 13, the supporting position of the main connecting rod 16 on the roof can be adaptively adjusted. When unfolded, the roof tent is in a wedge-shaped structure, and one end has a certain height space.

[0056] When retracting, because 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 on the left end of the guide groove 151. The actuator 18 moves in the opposite direction, driving the bottom slider 14 to move to the right, and the main connecting rod 16 and the side rod 17 retract downward. When fully retracted, the actuator 18 continues to pull the bottom slider 14 to move to the right, and the pin shaft and the locking rod 161 move to the right synchronously. The locking rod 161 is inserted into the locking groove 152, and one end of the main connecting rod 16 is inserted into the lock buckle, so that the lifting assembly 1 is completely locked; and there will be no shaking of the roof and accidental unlocking during driving, with high reliability. The guide assembly 2 retracts downward synchronously.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should all be included in the protection scope of the claims of the present invention.
