Description

Technical Field

[0001] This utility model belongs to the technical field of outdoor camping products, and in particular refers to a wheeled linkage lifting roof tent. Background Technology

[0002] The pop-up roof tent, an innovative piece of outdoor gear, is undoubtedly a powerful tool for outdoor enthusiasts. Not only is it compatible with various vehicles, easy to install and operate, but it also brings unprecedented convenience to our outdoor adventures. The tent's deployment and take-down are as natural and quick as flowing water, eliminating the need for a complicated setup process. The spacious interior can comfortably accommodate multiple people, adding more enjoyment to family camping or adventure activities.

[0003] The powerful functionality of a car-mounted pop-up tent goes far beyond this. It can also serve as storage space for luggage or other items, adding extra storage to your vehicle and meeting various outdoor activity needs. Even more noteworthy is its multi-functional design, most notably the foldable flap. This clever design increases the flexibility of the tent's interior, giving users more room to move around inside.

[0004] Previously, the applicant had applied for a patent for a folding tent frame, patent number 2022227157336. This tent frame is equipped with a bed board, i.e., a flip-up board, which can be rotated and unfolded to be located outside the base frame assembly. However, the flip-up board function currently still requires manual operation, which is relatively cumbersome, and the degree of automation needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a wheel-driven, linkage-operated, lifting roof tent, which features wheel transmission and can automatically rotate the flap during lifting and lowering, making it convenient to use and highly automated.

[0006] To achieve the above objectives, the solution of this utility model is: a wheel-type linkage lifting roof tent, including a first transmission wheel, a second transmission wheel, a conveyor belt, a linkage assembly, a first base frame, a top frame, an upper scissor-type lifting frame, a flap, and a drive device;

[0007] A flap is rotatably connected to the side of the first base frame. The flap can be folded over the first base frame or extended to the outside of the first base frame. An upper scissor lift is provided between the first base frame and the top frame to drive the top frame to descend and cover the flap and the first base frame, or to rise away from the flap and the first base frame.

[0008] The upper scissor lift includes a first branch and a second branch that are cross-hinged. The upper and lower ends of the first branch and the second branch are respectively pivotally connected to the top frame and the first base frame. Moreover, the upper end of the first branch and the lower end of the second branch are also sliding ends located on the same side. The two sliding ends are respectively slidably set on the top frame and the first base frame. The drive device is connected to at least one branch to drive the two branches to rotate and open around the central hinge.

[0009] The first and second drive wheels are rotatably mounted on one side of the first base frame, one to the left and one to the right. A conveyor belt is wound around the first and second drive wheels. One end of the connecting rod assembly is pivotally connected to the upper edge of the conveyor belt, and the other end of the connecting rod assembly is connected to the upper part of the flip plate. A connecting piece is sleeved and fixed to the lower edge of the conveyor belt. The lower end of the second branch of the upper scissor lift frame is connected to the connecting piece. When the drive device drives the top frame to descend, the sliding end pushes the conveyor belt to rotate and pulls the flip plate to rotate and fold above the first base frame. When the drive device drives the top frame to rise, the sliding end pushes the conveyor belt to rotate in the opposite direction and pushes the flip plate to rotate and extend to the outside of the first base frame.

[0010] Furthermore, the first conveyor wheel is the first pulley, the second conveyor wheel is the second pulley, and the conveyor belt is a steel wire rope.

[0011] Furthermore, the first conveyor belt is a first pulley, the second conveyor wheel is a second pulley, and the conveyor belt is a belt.

[0012] Furthermore, there are two flaps, which are symmetrically arranged in the same direction. One end of the linkage assembly is connected to the sliding end, and the other end of the linkage assembly is connected to the upper part of the two flaps respectively.

[0013] Furthermore, the linkage assembly includes a first linkage and a second linkage. One end of the first linkage is pivotally connected to the upper edge of the conveyor belt, and the other end of the first linkage is pivotally connected to the upper part of an adjacent flap. One end of the second linkage is pivotally connected to the lower edge of the conveyor belt, and the other end of the second linkage is pivotally connected to the upper part of another flap.

[0014] Furthermore, it also includes a second base frame and a lower scissor lift frame. The second base frame is located below the first base frame and is mounted on the vehicle. The lower scissor lift frame is located between the second base frame and the first base frame. The lower scissor lift frame has the same structure as the upper scissor lift frame, both including a first branch and a second branch that are cross-hinged. The upper and lower ends of the first and second branches of the lower scissor lift frame are respectively pivotally connected to the first and second base frames. Moreover, the upper end of the first branch and the lower end of the second branch are also sliding ends located on the same side. The two sliding ends are respectively slidably mounted on the first and second base frames, and the two branches rotate to open and close around the central hinge. The lower end of the first branch of the upper scissor lift frame and the upper end of the second branch of the lower scissor lift frame are coaxially pivotally fixed to the first base frame. The two sliding ends of the lower end of the second branch of the upper scissor lift frame and the upper end of the first branch of the lower scissor lift frame are connected together to a connecting piece.

[0015] The upper and lower scissor lifts are set as one set of scissor lifts. The vehicle-mounted lifting tent is equipped with two sets of scissor lifts, and another set of scissor lifts is symmetrically set on the other side of the first base frame.

[0016] Furthermore, the connecting piece is provided with a groove parallel to the conveyor belt, and the bolt passes through the groove. The bolt coaxially connects the lower end of the second branch of the upper scissor lift frame and the upper end of the first branch of the lower scissor lift frame.

[0017] Furthermore, a synchronizing rod is provided between the two sets of scissor lift frames. The two ends of the synchronizing rod are fixedly connected to the two symmetrical sliding ends on both sides, and the two sets of scissor lift frames open and close in conjunction with the synchronizing rod.

[0018] Furthermore, it also includes a height-increasing plate, which is a vertical sheet-like body. The lower end of the height-increasing plate is fixedly connected to the lower edge of the conveyor belt, and the upper end of the height-increasing plate is pivotally connected to one end of the second connecting rod, so that the second connecting rod and the first connecting rod are symmetrical and have the same height. The other end of the second connecting rod is pivotally connected to the upper part of another flip plate.

[0019] Furthermore, the lifting and lowering strokes of the top frame are both greater than the folding and unfolding strokes of the flap.

[0020] After adopting the above solution, the gain effect of this utility model is as follows:

[0021] 1. Stability: The lifting movement between the top frame and the first base frame is achieved through a scissor lift, while the flaps are driven to fold and unfold via a linkage assembly. This design ensures stable linkage between the flaps and the lift, keeping the tent stable during lifting and lowering, and effectively preventing it from being blown over or swaying even in severe weather conditions.

[0022] 2. Convenience: The linked flap design simplifies the tent installation and disassembly process. Users only need to operate one drive device to achieve synchronous movement of the flaps on both sides of the tent, greatly reducing the complexity and time required for operation.

[0023] 3. Safety: Since the flap is directly related to the raising and lowering of the tent, this design effectively prevents children or pets from accidentally getting caught between the tent and the flap, enhancing the safety of use.

[0024] 4. Aesthetics: The linked flap can be folded away when not in use, making the tent look neater and more attractive, thus enhancing the user's living experience. This design not only emphasizes practicality but also aesthetics, providing users with a better experience. Attached Figure Description

[0032] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1:

[0034] This utility model provides a wheeled, linkage-operated, lifting roof tent, such as... Figures 1 to 4 As shown, it includes a first base frame 1, a top frame 2, an upper scissor lift frame 3, a flip plate 4, a drive device 5, a first transmission wheel, a second transmission wheel, a conveyor belt, and a connecting rod assembly 7. In this embodiment, the first transmission wheel is a first pulley 61, the second transmission wheel is a second pulley 62, and the conveyor belt is a steel wire rope 63.

[0035] The side of the first base frame 1 is rotatably connected to a flap 4. In this case, there is no limit to the number of flaps 4. It is preferable to design two flaps 4, which are symmetrically arranged in the same direction.

[0036] Several rotating parts 11 are provided at the rotation point of the first base frame 1 and the flip plate 4. Each rotating part 11 includes two L-shaped connectors and a pivot. One end of the two L-shaped connectors is fixed to the first base frame 1 and the flip plate 4 respectively, and the other ends of the two L-shaped connectors are pivotally connected together by the pivot to form a V-shaped structure. The flip plate 4 can rotate and fold above the first base frame 1 (not shown in the figure) or rotate and extend to the outside of the first base frame 1, such as... Figure 1 As shown.

[0037] An upper scissor lift 3 is provided between the first base frame 1 and the top frame 2 to drive the top frame 2 to descend and cover the flap 4 and the first base frame 1, or to rise away from the flap 4 and the first base frame 1.

[0038] The upper scissor lift frame 3 includes a first branch 31 and a second branch 32 that are cross-hinged. The upper and lower ends of the first branch 31 and the second branch 32 are respectively pivotally connected to the top frame 2 and the first base frame 1. The upper end of the first branch 31 and the lower end of the second branch 32 are also sliding ends 33 located on the same side. The two sliding ends 33 are respectively slidably arranged on the top frame 2 and the first base frame 1. The drive device 5 is connected to at least one branch to drive the two branches 31 and 32 to rotate and open and close around the central hinge. The drive device 5 can drive the movement of one branch of the upper scissor lift frame 3 to drive the two branches to rotate and open and close around the central hinge.

[0039] This utility model of a vehicle-mounted lifting tent can be designed with only one base frame (first base frame 1), which is installed on the vehicle, or it can be designed with a double base frame, which can provide two storage spaces, one above the other, for a larger space.

[0040] This utility model also includes a second base frame 8 and a lower scissor lift frame 9. In this case, the first base frame 1 is not installed on the vehicle, but the second base frame 8 is installed on the vehicle. The second base frame 8 is located below the first base frame 1. The lower scissor lift frame 9 is arranged between the second base frame 8 and the first base frame 1. The lower scissor lift frame 9 has the same structure as the upper scissor lift frame 3, both including a first branch 31 and a second branch 32 that are cross-hinged. The upper and lower ends of the first branch 31 and the second branch 32 of the lower scissor lift frame 9 are respectively pivotally connected to the first base frame 1 and the second base frame 8. Moreover, the upper end of the first branch 31 and the lower end of the second branch 32 are also sliding ends 33 located on the same side. The two sliding ends 33 are respectively slidably arranged on the first base frame 1 and the second base frame 8. The two branches rotate to open and close around the central hinge. The lower end of the first branch 31 of the upper scissor lift frame 3 and the upper end of the second branch 32 of the lower scissor lift frame 9 are coaxially pivotally fixed on the first base frame 1.

[0041] The linkage assembly 7 consists of several linkages. In this embodiment, it preferably includes a first linkage 71 and a second linkage 72. The first pulley 61 and the second pulley 62 are rotatably disposed on one side of the first base frame 1, one to the left and the other to the right. A steel wire rope 63 is wound between the first pulley 61 and the second pulley 62 to form a closed loop. The upper edge of the steel wire rope 63 is pivotally connected to one end of the first linkage 71, and the other end of the first linkage 71 is connected to the upper part of the adjacent flap 4. The lower edge of the steel wire rope 63 is fixedly connected to a heightening plate 67, which is pivotally connected to one end of the second linkage 72. The other end of the second linkage 72 is connected to another flap 4, and both the first linkage 71 and the second linkage 72 are connected to the flap 4. The upper part; a connecting piece 64 is also fixedly installed on the lower edge of the wire rope 63. The connecting piece 64 has a groove 65 parallel to the lower edge of the wire rope 63. A bolt 66 passes through the groove 65. The bolt 66 coaxially connects the lower end of the second branch 32 of the upper scissor lift 3 and the upper end of the first branch 31 of the lower scissor lift 9 to the two sliding ends 33. The two sliding ends 33 are set together, so that the upper scissor lift 3 and the lower scissor lift 9 can move synchronously. When the top frame 2 rises away from the first base frame 1, the first base frame 1 moves away from the second base frame 8. When the top frame 2 descends to cover the first base frame 1, the first base frame 1 folds onto the second base frame 8. To lower and retract the top frame 2, the two sliding ends 33 slide to the right, pushing the connecting piece 64 to move to the right. The connecting piece 64 then moves the lower edge of the wire rope 63 to the right. At the same time, the first pulley 61 and the second pulley 62 rotate, and the wire rope 63, in conjunction with the first pulley 61 and the second pulley 62, performs counterclockwise transmission. The upper edge of the wire rope 63 moves to the left, so that the upper and lower edges of the wire rope 63 simultaneously move in opposite directions with the first connecting rod 71 and the second connecting rod 72, pulling the connected flap 4 to fold onto the first base frame 1. To raise and open the top frame 2, the two sliding ends 33 slide to the left, pushing the connecting piece 64 to move to the left. Finally, the upper and lower edges of the wire rope 63 simultaneously move in opposite directions with the first connecting rod 71 and the second connecting rod 72, pushing the connected flap 4 to rotate and extend to the outside of the first base frame 1. To ensure that the flap can be closed by the top frame after folding, and to ensure that the flap only begins to unfold after the top frame rises, the lifting and lowering strokes of the top frame 2 in this design are both greater than the folding and unfolding stroke of the flap 4. The purpose of the slide 65 is to delay the automatic unfolding and storage of the flap 4 after lifting and lowering, and also to control that the top frame 2 is closed on the first base frame 1 after the flap 4 is folded, avoiding the situation where the top frame 2 cannot be closed after the flap 4 is folded.

[0042] While the tent is raised, lowered, unfolded, and folded up, the flip panel 4 also unfolds and folds up automatically, freeing up your hands, making it convenient to use, and saving time and effort.

[0043] Although the above embodiment provides a case where the other end of the linkage assembly 7 is connected to the lower end of the second branch 32 of the upper scissor lift frame 3 and the upper end of the first branch 31 of the lower scissor lift frame 9, the other end of the linkage assembly 7 can also be connected to other sliding ends besides these two sliding ends (the upper end of the first branch 31 of the upper scissor lift frame 3 and the lower end of the second branch 32 of the lower scissor lift frame 9), and linkage can also be achieved. The embodiment provided is only a preferred embodiment of this utility model and is not a limitation on the design of this case.

[0044] The height-increasing plate 67 is a vertical plate-shaped body. The height-increasing plate 67 can overcome the inherent height difference between the upper and lower edges of the wire rope 63, so that the second link 72 and the first link 71 are symmetrical and have the same height. In this way, the flaps 4 on both sides can move simultaneously when linked.

[0045] like Figure 1 and Figure 3 As shown, the upper parts of the two flaps 4 are respectively provided with a first connecting strip 68 and a second connecting strip 69 protruding from the upper part, and are respectively pivotally connected to the first connecting rod 71 and the second connecting rod 72. Specifically, there are two of each of the first connecting strip 68 and the second connecting strip 69, which are respectively provided on both sides of the flap 4 and protrude from the upper part. The structure of the first connecting strip 68 and the second connecting strip 69 can be the same. The first connecting strip 68 and the second connecting strip 69 are inverted T-shaped. The lower parts of the first connecting strip 68 and the second connecting strip 69 are fixed on the flap 4, and the upper parts of the first connecting strip 68 and the second connecting strip 69 protrude from the upper part of the flap 4. Specifically, the upper part of the flap 4 can refer to the upper surface of the flap 4, that is, the opposite surface folded on the first base frame 1.

[0046] This utility model does not limit the number of upper-level scissor lift frames 3 and lower-level scissor lift frames 9; there can be one of each or multiple. This embodiment takes multiple as an example. As shown in the attached figure, one upper-level scissor lift frame 3 and one lower-level scissor lift frame 9 are set as one set of scissor lift frames. The vehicle-mounted lifting tent is equipped with two sets of scissor lift frames, and another set of scissor lift frames is symmetrically arranged on the other side of the first base frame 1. Figure 1 As shown, a synchronizing rod 10 is provided between the two sets of scissor lift frames. The two ends of the synchronizing rod 10 are fixedly connected to the bolts 66 on both sides, and the two sets of scissor lift frames open and close in conjunction with each other through the synchronizing rod 10.

[0047] The driving device 5 described in this utility model is an electric driving device 5 or a manual driving device 5 including a crank 51 (e.g., Figure 4As shown, the output end of the drive device 5 is connected to a ball screw 52. A screw nut 101, which mates with the ball screw 52, ​​is provided on the synchronizing rod 10. The rotation of the ball screw 52 drives the synchronizing rod 10 and its sliding ends 33 at both ends to slide through the mating screw nut 101. Specifically, both ends of the synchronizing rod 10 extend to form an arc-shaped bracket 102 on the same side. The screw nut 101 is mounted on the arc-shaped bracket 102. The synchronizing rod 10 moves together with the synchronizing rod 10 through the arc-shaped bracket 102, which improves the smoothness of the movement of the synchronizing rod 10. The above is only one structure of the drive device; the drive device can also adopt the same driving method as the side linkage assembly 7.

[0048] The storage process of the telescopic tent in this embodiment is as follows:

[0049] First, the crank handle 51 is driven to rotate, which in turn drives the synchronizing rod 10 to move to the right via the ball screw 52 and screw nut 101. Simultaneously, the synchronizing rod 10 moves to the right, causing the two sliding ends 33 connected to it to slide within the slide groove 65. At this time, the two branches 31 and 32 of the upper scissor lift frame 3 slowly merge, and the two branches of the lower scissor lift frame 9 also slowly merge, causing the top frame 2 to move closer to the first base frame 1, and the first base frame 1 to move closer to the second base frame 8. Then, when the sliding end 33 slides to the end of the slide groove 65, the sliding end 3... 3. The lower edge of the wire rope 63 is pushed to the right by the connecting piece 64. At the same time, the wire rope 63 rotates in conjunction with the first pulley 61 and the second pulley 62. The upper edge of the wire rope 63 moves to the left. Thus, the lower edge of the wire rope 63 is pulled by the second connecting rod 72 and folded onto the first base frame 1 by the flip plate 4. The upper edge of the wire rope 63 is pulled by the first connecting rod 71 and folded onto the first base frame 1 by the flip plate 4. Finally, when the flip plate 4 is folded, the top frame 2 covers the flip plate 4 and the first base frame 1, and the crank handle 51 stops rotating.

[0050] The deployment process of the lifting tent in this embodiment is as follows:

[0051] First, the crank handle 51 is driven to rotate in the reverse direction, which drives the synchronizing rod 10 to move to the left via the ball screw 52 and screw nut 101. Simultaneously, the leftward movement of the synchronizing rod 10 causes the two sliding ends 33 connected to it to slide within the slide groove 65. At this time, the two branches 31 and 32 of the upper scissor lift frame 3 slowly open, and the two branches of the lower scissor lift frame 9 also slowly open, causing the top frame 2 to move away from the first base frame 1, and the first base frame 1 to move away from the second base frame 8. Then, when the sliding end 33 slides to the initial end of the slide groove 65, the sliding end 3... 3. The lower edge of the wire rope 63 is pushed to the left by the connecting piece 64. At the same time, the wire rope 63 rotates in the opposite direction with the first pulley 61 and the second pulley 62. The upper edge of the wire rope 63 moves to the right. Thus, the lower edge of the wire rope 63 pushes the connected flap 4 to unfold on the outside of the first base frame 1 through the second connecting rod 72. The upper edge of the wire rope 63 pushes the connected flap 4 to unfold on the other outside of the first base frame 1 through the first connecting rod 71. Finally, when the flap 4 is fully unfolded, the top frame 2 is opened to the limit position and the crank handle 51 stops rotating in the opposite direction.

[0052] In order to completely close the cover, the outer edge of the top frame 2 forms a downwardly bent cover edge 21. When the top frame 2 descends to close the flap 4 and the first base frame 1, the cover edge 21 covers the outside of the flap 4 and the first base frame 1, so that the top frame 2 and the first base frame 1 are folded into a box-like structure.

[0053] Example 2:

[0054] The difference between Example 2 and Example 1 is as follows: Figure 5 As shown, the first conveyor belt is a first pulley 73, the second conveyor wheel is a second pulley 74, and the conveyor belt is a belt 75. During operation, the first pulley 73 and the second pulley 74 drive the belt 75 to rotate.

[0055] Unless otherwise expressly defined, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" in the claims, description, and accompanying drawings of this utility model is merely for the convenience of describing the utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as limiting the specific protection scope of this utility model.

[0056] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.

An upper-level scissor lift and a lower-level scissor lift are set as one set of scissor lifts. The roof tent is equipped with two sets of scissor lifts, and another set of scissor lifts is symmetrically set on the other side of the first base frame.

8. A wheeled, linkage-driven, lifting roof tent as described in claim 7, characterized in that: The connecting piece is provided with a groove parallel to the conveyor belt. Bolts are inserted in the groove and coaxially connect the lower end of the second branch of the upper scissor lift frame and the upper end of the first branch of the lower scissor lift frame.

9. A wheeled, linkage-type lifting roof tent as described in claim 1, characterized in that: A synchronizing rod is provided between the two sets of scissor lift frames. The two ends of the synchronizing rod are fixedly connected to the two symmetrical sliding ends on both sides. The two sets of scissor lift frames open and close in conjunction with the synchronizing rod.

10. A wheeled, linkage-driven, lifting roof tent as described in claim 1, characterized in that: The lifting and lowering stroke of the top frame is greater than the folding and unfolding stroke of the flap.
