Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a lifting bracket and a roof tent including the lifting bracket. Background Technology

[0002] A rooftop tent is a type of tent installed on a vehicle, primarily used to provide a portable resting space for camping. Existing rooftop tents include a top cover, a bottom cover, tent fabric, and a lift-up frame. The lift-up frame connects the top and bottom covers and can extend and retract between them. The rooftop tent is opened and closed with the assistance of the lift-up frame.

[0003] However, existing roof-mounted brackets lack stability. Sometimes, after retraction, they fail to close completely, resulting in incomplete parallel closure of the top and bottom covers and a poor seal, making it easy for rainwater to leak in. Furthermore, the precision requirements for the installation position of existing roof-mounted brackets on rooftop tents are extremely stringent. Impacts to the rooftop tent can easily cause deviations in the bracket's installation position, hindering smooth opening and closing and severely impacting the user experience. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is to provide a lifting bracket with high stability, smooth opening and closing, and the ability to completely close the roof tent.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a lifting bracket, including a sliding rod, a long middle rod, a bottom rod, a top rod, and a short middle rod. The sliding rod and the long middle rod are arranged crosswise and hinged to each other at the intersection. The bottom end of the sliding rod and the bottom end of the long middle rod are respectively hinged to both ends of the bottom rod, and the bottom end of the sliding rod can slide along the length direction of the bottom rod. The top end of the sliding rod is hinged to one end of the top rod. The two ends of the short middle rod are respectively hinged to the other end of the top rod and the top end of the long middle rod. The length of the short middle rod is less than the length of the long middle rod. One of the bottom rod and the top rod is used to connect to the bottom cover of the roof tent, and the other is used to connect to the top cover of the roof tent.

[0007] Preferably, it also includes a sliding member, on which a sliding groove extending along the length direction of the bottom rod is provided at the end where the bottom end of the base rod is hinged to the sliding groove, and the bottom end of the sliding rod is hinged to the sliding groove through the sliding member and slides in cooperation with the sliding groove.

[0008] Preferably, the base rod has two sliding grooves, which are spaced apart and opposite to each other in a direction perpendicular to the length of the base rod. The bottom end of the slide rod is connected to the middle of the sliding member, and the two ends of the sliding member are respectively connected to the two sliding grooves.

[0009] Preferably, the sliding member is hinged to the bottom end of the sliding rod, and the sliding member slides into the sliding groove.

[0010] Preferably, the sliding member is rotatably disposed within the sliding groove.

[0011] Preferably, the sliding member is fixedly connected to the bottom end of the sliding rod, and the sliding member is rotatably disposed in the sliding groove and slides in cooperation with the sliding groove.

[0012] Preferably, the sliding component includes a rolling bearing and a hinge shaft. The hinge shaft is located at the bottom end of the sliding rod. The inner ring of the rolling bearing is connected to the hinge shaft, and the outer ring of the rolling bearing is in sliding engagement with the sliding groove.

[0013] Preferably, at least one of the slide bar, the long middle bar, and the short middle bar has a curved arc.

[0014] Preferably, the slide bar and / or the long middle bar have a curved arc, with the slide bar curving in opposite directions on both sides of the intersection of the slide bar and the long middle bar, and the long middle bar curving in opposite directions on both sides of the intersection of the slide bar and the long middle bar.

[0015] This utility model also provides a rooftop tent, including the raised support frame as described above.

[0016] Compared with the prior art, this utility model has significant progress:

[0017] The lifting bracket of this utility model is constructed by intersecting a sliding rod and a long central rod, which are hinged together at the intersection. The sections of the sliding rod and the long central rod above the intersection, together with the top rod and the short central rod, form a double-crank structure. The bottom ends of the sliding rod and the long central rod are respectively hinged to the two ends of the base rod, and the bottom end of the sliding rod can slide along the length of the base rod. When the lifting bracket extends or retracts, the sliding rod, the long central rod, the base rod, the top rod, and the short central rod move in coordination through the hinge points. At the same time, the bottom end of the sliding rod slides along the length of the base rod, thus making the entire lifting bracket highly stable and smooth in opening and closing. Furthermore, when the lifting bracket is connected to a rooftop tent, even if the rooftop tent is subjected to a certain impact, the lifting bracket can still remain stable and open and close smoothly.

[0035] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0036] like Figures 1 to 4The image shows one embodiment of the lifting bracket provided by this utility model.

[0037] See Figures 1 to 3 The lifting bracket in this embodiment includes a sliding rod 1, a long middle rod 2, a bottom rod 3, a top rod 4, and a short middle rod 5. The sliding rod 1 and the long middle rod 2 are arranged crosswise and hinged to each other at their intersection. Both the sliding rod 1 and the long middle rod 2 can rotate around their intersection point, thereby changing the included angle between them. The bottom ends of the sliding rod 1 and the long middle rod 2 are hinged to both ends of the bottom rod 3, and the bottom end of the sliding rod 1 can slide along the length of the bottom rod 3. The length direction of the bottom rod 3 is the extension direction from one end of the bottom rod 3 to the other end. Sliding the bottom end of the sliding rod 1 along the length direction of the bottom rod 3 allows the bottom ends of the sliding rod 1 and the long middle rod 2 to move away from or towards each other. The top end of the sliding rod 1 is hinged to one end of the top rod 4. The two ends of the short middle rod 5 are hinged to the other end of the top rod 4 and the top end of the long middle rod 2, respectively. The length of the short middle rod 5 is less than the length of the long middle rod 2. The sections of the sliding rod 1 and the long middle rod 2 above their intersection, together with the top rod 4 and the short middle rod 5, form a double-crank structure. One of the bottom rod 3 and the top rod 4 is used to connect to the bottom cover 6 of the roof tent, and the other is used to connect to the top cover 7 of the roof tent. Thus, when the lifting bracket is connected to the roof tent, the roof tent opens and closes between the bottom cover 6 and the top cover 7 via the lifting bracket.

[0038] See Figure 1 When the bottom end of the sliding rod 1 slides away from the bottom end of the long middle rod 2 along the length direction of the bottom rod 3, the sliding rod 1 rotates around the bottom end of the sliding rod 1 toward the bottom rod 3, and the long middle rod 2 rotates around the bottom end of the long middle rod 2 toward the bottom rod 3. The intersection of the sliding rod 1 and the long middle rod 2 gradually moves closer to the bottom rod 3. During this process, the top end of the sliding rod 1 and the top end of the long middle rod 2 move away from each other. Since the top end of the sliding rod 1 is hinged to one end of the top rod 4, and the two ends of the short middle rod 5 are hinged to the other end of the top rod 4 and the top end of the long middle rod 2 respectively, the end of the top rod 4 that is hinged to the top end of the sliding rod 1 and the end of the short middle rod 5 that is hinged to the top end of the long middle rod 2 also move away from each other. At the same time, the top rod 4 rotates downward around the top end of the sliding rod 1, and the short middle rod 5 rotates downward around the top end of the long middle rod 2, so that the hinge point between the top rod 4 and the short middle rod 5 also gradually moves closer to the bottom rod 3. As the intersection of slide rod 1 and long middle rod 2, and the hinge point between top rod 4 and short middle rod 5 gradually move closer to and fit into bottom rod 3, slide rod 1, long middle rod 2, bottom rod 3, top rod 4 and short middle rod 5 eventually fold together, and the entire lifting support is in a contracted and closed state.

[0039] See Figure 2 and Figure 3When the bottom end of the sliding rod 1 slides along the length of the base rod 3 towards the bottom end of the long middle rod 2, the sliding rod 1 rotates away from the base rod 3 around its bottom end, and the long middle rod 2 rotates away from the base rod 3 around its bottom end. The intersection of the sliding rod 1 and the long middle rod 2 gradually rises away from the base rod 3. During this process, the top ends of the sliding rod 1 and the long middle rod 2 approach each other. Since the top end of the sliding rod 1 is hinged to one end of the top rod 4, and the two ends of the short middle rod 5 are hinged to the other end of the top rod 4 and the top end of the long middle rod 2 respectively, the end of the top rod 4 that is hinged to the top end of the sliding rod 1 and the end of the short middle rod 5 that is hinged to the top end of the long middle rod 2 also approach each other. At the same time, the top rod 4 rotates upward around the top end of the sliding rod 1, and the short middle rod 5 rotates upward around the top end of the long middle rod 2, so that the hinge point between the top rod 4 and the short middle rod 5 also gradually rises away from the base rod 3. As the intersection of the sliding rod 1 and the long middle rod 2, and the hinge point between the top rod 4 and the short middle rod 5 gradually rise away from the bottom rod 3, the sliding rod 1, the long middle rod 2, the bottom rod 3, the top rod 4 and the short middle rod 5 eventually form an unfolded three-dimensional structure, and the entire lifting support is in an extended and open state.

[0040] Therefore, in this embodiment, the lifting bracket is constructed by intersecting the sliding rod 1 and the long middle rod 2 and hinged to each other at the intersection. The rods above the intersection of the sliding rod 1 and the long middle rod 2, together with the top rod 4 and the short middle rod 5, form a double crank structure. The bottom ends of the sliding rod 1 and the long middle rod 2 are respectively hinged to the two ends of the bottom rod 3, and the bottom end of the sliding rod 1 can slide along the length of the bottom rod 3. When the lifting bracket extends or retracts, the sliding rod 1, the long middle rod 2, the bottom rod 3, the top rod 4, and the short middle rod 5 move in coordination through the hinge points. At the same time, the bottom end of the sliding rod 1 slides along the length of the bottom rod 3, thereby making the entire lifting bracket highly stable and smooth in opening and closing. Furthermore, when the lifting bracket is connected to the roof tent, even if the roof tent is subjected to a certain impact, the lifting bracket can still remain stable and open and close smoothly.

[0041] See Figures 1 to 3Preferably, the lifting bracket in this embodiment further includes a sliding member 11. A sliding groove 31 extending along the length of the base rod 3 is provided on the end of the base rod 3 that is hinged to the bottom end of the slide rod 1. The bottom end of the slide rod 1 is hinged to the sliding groove 31 via the sliding member 11 and slides in cooperation with the sliding groove 31. The bottom end of the slide rod 1 can slide smoothly along the sliding groove 31 via the sliding member 11. The sliding groove 31 provides a fixed sliding path for the bottom end of the slide rod 1, ensuring that the bottom end of the slide rod 1 always slides along the length of the base rod 3. The cooperation between the sliding member 11 and the sliding groove 31 prevents the bottom end of the slide rod 1 from shifting or wobbling during sliding. The length of the sliding groove 31 determines the sliding range of the bottom end of the slide rod 1, thus affecting the state of the lifting bracket when it extends and retracts. In this embodiment, the length of the sliding groove 31 ensures that when the bottom end of the slide rod 1 slides along the sliding groove 31 through the sliding member 11, the lifting bracket smoothly transitions from a fully contracted and closed state to a fully extended and open state, thus meeting the height adjustment requirements of the lifting bracket in actual use.

[0042] In this embodiment, preferably, two sliding grooves 31 are formed on the base rod 3. The two sliding grooves 31 are spaced apart and opposite to each other in a direction perpendicular to the length direction of the base rod 3. The bottom end of the slide rod 1 is connected to the middle of the sliding member 11, and the two ends of the sliding member 11 are respectively connected to the two sliding grooves 31. The two ends of the sliding member 11 cooperate with the two sliding grooves 31 respectively, so that both sides of the slide rod 1 are subjected to force simultaneously during the sliding process, avoiding the bottom end of the slide rod 1 from shifting or shaking due to uneven force. As a result, the bottom end of the slide rod 1 is more stable during the sliding process, further enhancing the overall stability of the lifting support structure.

[0043] In one embodiment of this invention, preferably, the sliding member 11 is hinged to the bottom end of the sliding rod 1, and the sliding member 11 is slidably engaged with the sliding groove 31. This allows the bottom end of the sliding rod 1 to be hinged to the sliding groove 31 via the sliding member 11 and to slide in a sliding engagement with the sliding groove 31, enabling the sliding rod 1 to rotate relative to the bottom rod 3 and slide along the sliding groove 31. Furthermore, the sliding member 11 is rotatably disposed within the sliding groove 31, meaning that the sliding member 11 is both slidably engaged with and rotatably engaged with the sliding groove 31, resulting in rolling friction between the sliding member 11 and the sliding groove 31. This significantly reduces the friction and wear of the sliding member 11 when sliding within the sliding groove 31.

[0044] In another embodiment of this invention, preferably, the sliding member 11 is fixedly connected to the bottom end of the sliding rod 1. The sliding member 11 is rotatably disposed within the sliding groove 31 and slides in cooperation with the sliding groove 31. This also allows the bottom end of the sliding rod 1 to be hinged to the sliding groove 31 via the sliding member 11 and slide in cooperation with the sliding groove 31, enabling the sliding rod 1 to rotate relative to the bottom rod 3 and slide along the sliding groove 31. The fixed connection between the sliding member 11 and the bottom end of the sliding rod 1 maintains stability, preventing the bottom end of the sliding rod 1 from being unable to slide smoothly in the sliding groove 31 due to loosening of the connection between the sliding member 11 and the bottom end of the sliding rod 1.

[0045] In this embodiment, preferably, the sliding member 11 includes a rolling bearing and a hinge shaft. The hinge shaft is located on the bottom end of the slide rod 1. The bottom end of the slide rod 1 and the hinge shaft can be hinged or fixedly connected. The inner ring of the rolling bearing is connected to the hinge shaft, and the outer ring of the rolling bearing slides into the sliding groove 31. The rolling friction between the rolling bearing and the sliding groove 31 significantly reduces the friction force when the bottom end of the slide rod 1 slides in the sliding groove 31. Therefore, the bottom end of the slide rod 1 slides more smoothly on the base rod 3, making the lifting bracket extend and retract more smoothly. Furthermore, a rolling bearing is connected to each end of the hinge shaft. The two rolling bearings are located on opposite sides of the bottom end of the slide rod 1. The bottom end of the slide rod 1 slides into the two sliding grooves 31 on the base rod 3 through the rolling bearings on both sides. This avoids the bottom end of the slide rod 1 being subjected to force on one side, which would cause offset or shaking during the sliding process, thus ensuring the overall structural stability of the lifting bracket.

[0046] See Figures 1 to 3 Preferably, at least one of the sliding rod 1, the long middle rod 2, and the short middle rod 5 has a bending arc. Designing a bending arc on the rods of the lifting support can reduce the risk of excessive local stress in the rods leading to structural deformation or damage, making the lifting support less prone to bending or deformation when subjected to large loads, thereby improving the stress performance of the lifting support.

[0047] In this embodiment, preferably, both the sliding rod 1 and / or the long middle rod 2 have a curved arc, that is, the sliding rod 1 of the lifting bracket has a curved arc, or the long middle rod 2 of the lifting bracket has a curved arc, or both the sliding rod 1 and the long middle rod 2 of the lifting bracket have curved arcs. Further, the sliding rod 1, the long middle rod 2, and the short middle rod 5 all have curved arcs. Specifically, the bending directions of the sliding rod 1 and the long middle rod 2 are opposite on both sides of the intersection point, and the bending directions of the long middle rod 2 are also opposite on both sides of the intersection point. The opposite bending directions of the rods at the intersection point further disperse the stress borne by the rods, preventing local stress concentration that could lead to rod damage, and also improving the overall aesthetics of the lifting bracket.

[0048] Based on the lifting bracket of this utility model, this utility model embodiment also provides a rooftop tent, which includes the lifting bracket described above.

[0049] See Figure 4 The rooftop tent in this embodiment also includes a bottom cover 6 and a top cover 7. A lifting bracket is connected between the bottom cover 6 and the top cover 7 to assist in opening and closing the bottom cover 6 and the top cover 7. Preferably, the bottom rod 3 of the lifting bracket is connected to the bottom cover 6, and the top rod 4 of the lifting bracket is connected to the top cover 7. When the lifting bracket is in the extended state, the bottom cover 6 and the top cover 7 separate, allowing the rooftop tent to fully open and form a usable storage space; when the lifting bracket is in the retracted and closed state, the bottom cover 6 and the top cover 7 are pressed together, allowing the rooftop tent to fully close.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
