Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor camping supplies, in particular to a linkage type vehicle-mounted lifting tent. Background Art

[0002] With the increasing popularity of outdoor activities and camping culture, car-mounted tents, as convenient and practical camping equipment, have been favored by the majority of users. A car-mounted lifting tent is a specially designed tent that is combined with a vehicle (usually an SUV, MPV or pickup truck with a large roof) and can be quickly unfolded and folded on the roof through a lifting mechanism.

[0003] At present, most vehicle-mounted lifting tents on the market use a scissor-type lifting structure, which performs well in the deployment and folding of the bottom frame and top frame, providing users with a convenient operating experience. However, in actual use, these tents often face stability issues. Specifically, since the scissor-type lifting structure lacks sufficient stability control mechanism during the lifting process, it is prone to shaking and vibration during the lifting process, which not only affects the user's comfort, but may also cause long-term damage to the structure of the tent and reduce its service life. Utility Model Content

[0004] The purpose of the utility model is to provide a linkage type vehicle-mounted lifting tent, which solves the problem of poor structural stability of the tent during the lifting process through structural improvement, prolongs the product life, and improves the comfort of users.

[0005] To achieve the above-mentioned purpose, the solution of the utility model is: a linkage vehicle-mounted lifting tent, comprising a first bottom frame, a top frame, two sets of upper scissor-type lifting frames and a driving device;

[0006] Two sets of upper scissor-type lifting frames are arranged between the first bottom frame and the top frame, and are symmetrically arranged on both sides of the first bottom frame, so as to drive the top frame to descend to cover the first bottom frame, or to ascend away from the first bottom frame;

[0007] Each set of upper scissor-type lifting frames comprises a first fork and a second fork which are cross-hinged, and upper and lower ends of the first fork and the second fork are respectively pivotally connected to the top frame and the first bottom frame, and the upper end of the first fork and the lower end of the second fork are also sliding ends located on the same side, and the two sliding ends are respectively slidably arranged on the top frame and the first bottom frame;

[0008] A synchronization rod is provided between the two sets of upper scissor-type lifting frames, and the two ends of the synchronization rod are respectively fixedly connected to the sliding ends symmetrically on both sides. The driving device is connected to and drives the synchronization rod and the sliding ends connected thereto to slide along the length direction of the first base frame, thereby driving the two forks to rotate and open and close around the central hinge;

[0009] The bottom of the first base frame is provided with a slide rail extending along the length direction thereof, and the synchronization rod is provided with a plurality of pulleys. The synchronization rod is connected with the slide rail on the first base frame through the pulleys and slides along the slide rail.

[0010] Furthermore, the driving device is an electric driving device or a manual driving device, the output end of the driving device is connected to a ball screw, and the synchronization rod is provided with a screw nut that cooperates with the ball screw. The rotation of the ball screw drives the synchronization rod and the sliding ends at both ends to slide through the cooperating screw nut.

[0011] Furthermore, the two ends of the synchronization rod extend to the same side to form an arch-shaped bracket, and the lead screw nut is arranged on the arch-shaped bracket. The synchronization rod is driven to move together through the arch-shaped bracket, thereby driving the sliding ends connected to the two ends of the synchronization rod to slide.

[0012] Furthermore, the arch-shaped bracket is provided with pulleys on both sides of the slide rail, and the arch-shaped bracket is connected to the slide rail on the first base frame through the pulleys and slides along the slide rail.

[0013] Furthermore, two slide rails are symmetrically arranged at the bottom of the first chassis, and the pulleys on the synchronization rod and the arch-shaped bracket are also symmetrically arranged, and slide on the two slide rails respectively.

[0014] Furthermore, a bolt is pivotally connected to the sliding end connected to the synchronization rod, and a through slot extending along the length direction of the first chassis is opened on the side of the first chassis. The synchronization rod passes through the through slot and is fixedly connected to the bolt, thereby synchronously driving the sliding end to slide along the through slot.

[0015] Furthermore, the vehicle-mounted lifting tent also includes a second base frame and a lower scissor-type lifting frame, the second base frame is arranged below the first base frame, the second base frame is installed on the vehicle, and the lower scissor-type lifting frame is arranged between the second base frame and the first base frame, and the number of the lower scissor-type lifting frames is also two groups, which are symmetrically arranged on both sides of the first base frame;

[0016] The structure of the lower scissor-type lifting frame is the same as that of the upper scissor-type lifting frame, both of which include a cross-hinged first fork and a second fork, the upper and lower ends of the first fork and the second fork of the lower scissor-type lifting frame are pivoted to the first frame and the second frame respectively, and the upper end of the first fork and the lower end of the second fork are sliding ends located on the same side, the two sliding ends are slidably arranged on the first frame and the second frame respectively, and the two forks rotate around the central hinge to open and close; the lower end of the first fork of the upper scissor-type lifting frame and the upper end of the second fork of the lower scissor-type lifting frame are coaxially pivoted and fixedly arranged on the first frame, and the lower end of the second fork of the upper scissor-type lifting frame and the upper end of the first fork of the lower scissor-type lifting frame are coaxially pivoted and slidably arranged on the first frame.

[0017] Furthermore, a flap is rotatably connected to the side of the first base frame, and the flap is rotatably folded above the first base frame or rotatably extends to the outside of the first base frame.

[0018] Furthermore, it also includes a connecting rod mechanism, one end of which is connected to the flap, and the other end is connected to one of the sliding ends. When the driving device drives the top frame to descend, the sliding end slides and pulls the flap to rotate and fold above the first base frame. When the driving device drives the top frame to rise, the sliding end slides and pushes the flap to rotate and extend to the outside of the first base frame.

[0019] After adopting the above scheme, the gain effect of the utility model is:

[0020] The vehicle-mounted lifting tent of the utility model introduces the design of a synchronization rod on the basis of the scissor-type lifting structure. This improvement not only simplifies the driving mechanism and makes the entire tent structure lighter and more efficient, but more importantly, it significantly enhances the coordinated action between the two sets of upper scissor-type lifting frames. Through the precise regulation of the synchronization rod, the two sets of lifting frames can be opened and closed synchronously during the lifting process, which greatly improves the stability of the tent during the lifting process, effectively avoids shaking and vibration, and provides users with a more comfortable and safe camping experience.

[0021] In addition, in order to further improve the connection stability between the synchronization rod and the first chassis, the utility model specially designs a slide rail pulley structure. The pulley slide rail not only realizes the further connection between the synchronization rod and the first chassis, but also when the driving device drives the synchronization rod to slide along the length direction of the first chassis, the pulley slides smoothly in the slide rail, which not only ensures the accuracy of the movement trajectory of the synchronization rod, but also prevents the synchronization rod from shaking or deflecting during the sliding process, thereby improving the stability and reliability of the entire structure.

[0022] In summary, the vehicle-mounted lifting tent of the utility model achieves higher stability and reliability while maintaining lightness and high efficiency, providing users with a safer and more comfortable camping environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Embodiment 1:

[0044] The utility model provides a linkage type vehicle-mounted lifting tent, such as Figures 1 to 6 As shown, it includes a first base frame 1, a top frame 2, two sets of upper scissor-type lifting frames 3 and a driving device 5 for driving the lifting. The two sets of upper scissor-type lifting frames 3 are arranged between the first base frame 1 and the top frame 2, and are symmetrically arranged on both sides of the first base frame 1, so as to drive the top frame 2 to descend to cover the first base frame 1, or to rise away from the first base frame 1.

[0045] Each set of upper scissor-type lifting frames 3 includes a first fork 31 and a second fork 32 that are cross-hinged, and upper and lower ends of the first fork 31 and the second fork 32 are respectively pivotally connected to the top frame 2 and the first bottom frame 1, and the upper end of the first fork 31 and the lower end of the second fork 32 are also sliding ends 33 located on the same side, and the two sliding ends 33 are respectively slidably arranged on the top frame 2 and the first bottom frame 1;

[0046] A synchronization rod 4 is provided between the two sets of upper scissor lifts 3, and the two ends of the synchronization rod 4 are fixedly connected to the sliding ends 33 symmetrically on both sides, specifically, (such as Figure 1 The first chassis 1 is provided with a through slot 11 extending along the length direction of the first chassis 1, and the synchronous rod 4 passes through the through slot 11 and is fixedly connected to the bolt 43. The driving device 5 is connected to and drives the synchronous rod 4 and the sliding end 33 connected thereto to slide along the length direction of the first chassis 1, and synchronously drives the sliding end 33 to slide along the through slot 11, thereby driving the two forks 31, 32 to rotate and open around the central hinge. The design of the synchronous rod 4 enables the left and right sets of scissor-type lifting frames to move synchronously, ensuring the stability and balance during the lifting process of the tent.

[0047] In order to further improve the stability of the vehicle-mounted lifting tent structure, such as Figures 2 to 4 As shown, the utility model is particularly provided with a slide rail 12 extending along the length direction of the first chassis 1 at the bottom thereof, and a first pulley 61 is provided at a position corresponding to the slide rail 12 on the synchronization rod 4. The provision of the pulley and the slide rail 12 further enhances the connection stability between the synchronization rod 4 and the first chassis 1. The pulley not only realizes the further connection between the synchronization rod 4 and the first chassis 1, but also when the driving device 5 drives the synchronization rod 4 to slide along the length direction of the first chassis 1, the pulley slides smoothly in the slide rail 12, which not only ensures the accuracy of the motion trajectory of the synchronization rod 4, but also prevents the synchronization rod 4 from shaking or deflecting during the sliding process, thereby improving the stability and reliability of the entire structure.

[0048] The driving device 5 described in the present utility model is an electric driving device 5 or a manual driving device 5. Figures 2 to 4The output end of the driving device 5 is connected to a ball screw 51, and a screw nut 42 is provided on the synchronization rod 4 to cooperate with the ball screw 51. The ball screw 51 rotates through the screw nut 42 to drive the synchronization rod 4 and the sliding ends 33 at both ends to slide. Specifically, the two ends of the synchronization rod 4 extend to the same side to form an arch bracket 41, and the screw nut 42 is arranged on the arch bracket 41. The synchronization rod 4 is driven by the arch bracket 41 to move together with the synchronization rod 4, and then the sliding ends 33 connected to the two ends of the synchronization rod 4 are driven to slide. The arrangement of the arch bracket 41 can improve the stability of the movement of the synchronization rod 4.

[0049] The arched structure described in the present invention is not limited to the shapes of a bow, an arc or a part of a trapezoid, etc. The arched structure can be any shape formed by the two ends of the synchronization rod 4 extending to the same side. Figure 5 A, b, and c in the figure respectively show three possible arch structures, but these examples are not exhaustive, but are intended to illustrate the diversity and flexibility of the arch structure. In practical applications, the specific shape of the arch structure can be selected and adjusted according to actual needs and usage scenarios. Regardless of the shape of the arch structure selected, it is important to ensure that it can effectively connect the synchronization rod 4 to the first base frame 1 and provide sufficient stability and support to ensure the stability and safety of the vehicle-mounted lifting tent during the lifting process.

[0050] As a further improvement of the structure, the arched bracket 41 is also provided with pulley structures on both sides of the slide rail 12. The arched bracket 41 is connected to the slide rail 12 on the first chassis 1 through the pulleys and slides along the slide rail 12. Specifically, one side of the slide rail 12 is provided with a lateral slide groove 121, and the other side is a sliding surface 122 (such as Figure 4 As shown in FIG. 1 , correspondingly, the arched bracket 41 is provided with a second pulley 62 on one side of the slide rail 12, and a third pulley 63 on the other side of the slide rail 12. The first pulley 61 on the synchronization rod 4 and the second pulley 62 on the arched bracket 41 slide in the lateral slide groove 121 of the slide rail 12, and the third pulley 63 slides on the slide surface 122 of the slide rail 12. The arrangement of these pulleys on the arched bracket 41 is also to further enhance the connection stability between the arched bracket 41 and the first chassis 1.

[0051] This case has a certain degree of flexibility in the design of the number of slide rails 12, and no specific restrictions are imposed. However, in order to ensure the stability and uniformity of force of the tent during the lifting process, the slide rails 12 should be evenly distributed on the first chassis 1. This can effectively disperse the force generated by the synchronization rod 4 during the sliding process and reduce the risk of local overload. In the specific design, if a single slide rail 12 is used, it is set in the middle position of the first chassis 1 to ensure that the synchronization rod 4 is balanced when sliding. If you choose to design two slide rails 12, the two slide rails 12 should be symmetrically distributed on the first chassis 1, which can not only further improve the stability, but also ensure the consistency of force on both sides.

[0052] In this embodiment, our preferred design is to set two slide rails 12, a first pulley 61, a second pulley 62 and a third pulley 63 on the same slide rail 12 form a pulley group 6, and the two slide rails 12 are symmetrically arranged at the bottom of the first chassis 1. Correspondingly, the same number of pulley groups 6 are also symmetrically arranged on the synchronization rod 4 and the arch bracket 41, and these pulley groups 6 slide on the two slide rails 12 respectively. Such a design enables the synchronization rod 4 to slide smoothly and stably along the slide rail 12 under the action of the driving device 5, further improving the stability and reliability of the vehicle-mounted lifting tent. At the same time, the use of multiple pulleys also effectively reduces friction and wear, and prolongs the service life of the tent.

[0053] The working process of the vehicle-mounted lifting tent in this embodiment is as follows:

[0054] Storage process: First, the driving device 5 works to rotate the ball screw 51, and the synchronous rod 4 is driven to the right ( Figure 2 The synchronous rod 4 moves to the right and drives the two sliding ends 33 connected thereto to move along the through slot 11. At this time, the two forks 31 and 32 of the upper scissor-type lifting frame 3 slowly merge, so that the top frame 2 approaches the first bottom frame 1. Finally, the top frame 2 just covers the first bottom frame 1, and the driving device 5 stops working.

[0055] Unfolding process: The driving device 5 works to rotate the ball screw, and drives the synchronous rod 4 to the left ( Figure 2 The synchronous rod 4 moves to the left and drives the two sliding ends 33 to move in the opposite direction along the through slot 11. At this time, the two forks 31 and 32 of the upper scissor-type lifting frame 3 slowly open, so that the top frame 2 moves away from the first bottom frame 1. Finally, the top frame 2 is unfolded to the limit position, and the driving device 5 stops working.

[0056] In order to cover completely, the outer edge of the top frame 2 forms a downwardly bent cover edge 21. When the top frame 2 descends to cover the first bottom frame 1, the cover edge 21 wraps around the outside of the first bottom frame 1, so that the top frame 2 and the first bottom frame 1 are folded into a box-like structure.

[0057] To ensure that the flap 7 can be covered by the top frame 2 after being folded, and to ensure that the flap 7 begins to unfold only after the top frame 2 rises, the stroke of the top frame 2 in this case is greater than the stroke of the flap 7 folding or unfolding.

[0058] Key References Figure 1 and Figure 2 The side of the first bottom frame 1 is rotatably connected to a flap 7, which is folded and stored above the first bottom frame 1, or extended to the outside of the first bottom frame 1 to expand the activity space of the tent. The flap 7 can be unfolded and folded by manual flipping or by a connecting rod mechanism 8 (such as Figure 7 and Figure 8 ) is connected to the sliding end 33 of the scissor-type lifting frame to realize electric and linkage flipping. When the driving device 5 drives the top frame 2 to descend, the sliding end 33 slides and pulls the flap 7 to rotate and fold above the first bottom frame 1. When the driving device 5 drives the top frame 2 to rise, the sliding end 33 slides and pushes the flap 7 to rotate and extend outside the first bottom frame 1. The connecting rod mechanism 8 can be composed of any of the following transmission mechanisms: rack transmission mechanism, rocker transmission mechanism, toothed chain transmission mechanism, pulley transmission mechanism, and belt pulley transmission mechanism.

[0059] In addition, the present invention does not limit the number of flaps 7. It is preferred to design two flaps 7, and the two flaps 7 are symmetrically arranged in the same direction.

[0060] Embodiment 2:

[0061] The first embodiment introduces the case where the vehicle-mounted lifting tent of the utility model is designed with only one layer of chassis (first chassis 1), and the first chassis 1 is installed on the vehicle. The following is an embodiment of designing a double-layer chassis, which can provide two upper and lower accommodating spaces, and the space is larger.

[0062] like Figures 7 to 10 As shown, the vehicle-mounted lifting tent of the utility model further includes a second base frame 9 and a lower scissor-type lifting frame 10, the second base frame 9 is arranged below the first base frame 1, the second base frame 9 is installed on the vehicle, and the lower scissor-type lifting frame 10 is arranged between the second base frame 9 and the first base frame 1. The number of the lower scissor-type lifting frames 10 is also two groups, which are symmetrically arranged on both sides of the first base frame 1.

[0063] like Figure 7 and Figure 8As shown, the structure of the lower scissor-type lifting frame 10 is the same as that of the upper scissor-type lifting frame 3, both of which include a cross-hinged first fork 31 and a second fork 32. The upper and lower ends of the first fork 31 and the second fork 32 of the lower scissor-type lifting frame 10 are respectively pivoted to the first base frame 1 and the second base frame 9, and the upper end of the first fork 31 and the lower end of the second fork 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 9, and the two forks 31 and 32 rotate around the central hinge to open and close; the lower end of the first fork 31 of the upper scissor-type lifting frame 3 and the upper end of the second fork 32 of the lower scissor-type lifting frame 10 are coaxially pivoted and fixedly arranged on the first base frame 1, and the two sliding ends 33 of the lower end of the second fork 32 of the upper scissor-type lifting frame 3 and the upper end of the first fork 31 of the lower scissor-type lifting frame 10 are coaxially pivoted and slidably arranged on the first base frame 1. By arranging the upper and lower sliding ends 33 together, the upper scissor lift frame 3 and the lower scissor lift frame 10 can move synchronously to realize linkage. When the top frame 2 rises away from the first bottom frame 1, the first bottom frame 1 moves away from the second bottom frame 9. When the top frame 2 descends to cover the first bottom frame 1, the first bottom frame 1 is folded on the second bottom frame 9.

[0064] The working process of the vehicle-mounted lifting tent in this embodiment is as follows:

[0065] Storage process: First, the driving device 5 works to rotate the ball screw 51, and the synchronous rod 4 is driven to the right ( Figure 7 The synchronous rod 4 moves to the right and drives the two sliding ends 33 connected thereto to move along the through slot 11. At this time, the two forks 31, 32 of the upper scissor-type lifting frame 3 slowly merge, and the two forks 31, 32 of the lower scissor-type lifting frame 10 also slowly merge, so that the top frame 2 approaches the first bottom frame 1, and the first bottom frame 1 approaches the second bottom frame 9. Finally, the top frame 2 just covers the first bottom frame 1 and the second bottom frame 9, and the driving device 5 stops working.

[0066] Unfolding process: The driving device 5 works to rotate the ball screw, and drives the synchronous rod 4 to the left ( Figure 7 The synchronous rod 4 moves to the left and drives the two sliding ends 33 to move in the opposite direction along the through slot 11. At this time, the two forks 31 and 32 of the upper scissor-type lifting frame 3 are slowly opened, and the two forks 31 and 32 of the lower scissor-type lifting frame 10 are also slowly opened, so that the top frame 2 moves away from the first bottom frame 1, and the first bottom frame 1 moves away from the second bottom frame 9. Finally, the top frame 2 and the first bottom frame 1 are unfolded to the limit position, and the driving device 5 stops working.
