Description

A linkage type vehicle-mounted lifting tent and its use method Technical Field

[0001] The present invention belongs to the technical field of outdoor camping supplies, and in particular relates to a linked vehicle-mounted lifting tent and a method of using the same. Background Art

[0002] The vehicle-mounted lifting tent is a convenient and practical outdoor equipment suitable for various vehicles. The vehicle-mounted lifting tent is easy to install and operate, and can be easily and quickly unfolded and folded. The tent is spacious and comfortable and can accommodate multiple people to rest. It is very suitable for family camping, outdoor adventures and other occasions, or it can accommodate luggage and increase the storage space of the vehicle. In addition, with the continuous improvement of usage demand, the vehicle-mounted lifting tent is also designed with a variety of practical functions. For example, in order to expand the activity space inside the tent, a foldable flap is designed on the tent. The applicant previously applied for a folding tent frame with a bed board, patent number 2022227157336, which records that a bed board, i.e., a flap, is provided on one or both sides of the base frame assembly. The flap rotates and unfolds to the outside of the base frame assembly. After the flap is unfolded, the length of the base frame assembly can be increased, thereby providing users with space to lie flat.

[0003] However, the flap must be manually rotated to unfold and fold when in use, and the operations must be performed separately, and cannot be unfolded and folded at the same time, which is time-consuming and labor-intensive, and has a low degree of automation. Therefore, the applicant has designed a vehicle-mounted lifting tent that can rotate the flap in conjunction with the lifting. Technical issues

[0004] The purpose of the present invention is to provide a linkage type vehicle-mounted lifting tent and a method of using the same, wherein when the tent is raised, lowered, unfolded and folded, the flap is also linked to automatically unfold and folded, freeing the hands, being easy to use, saving time and effort, and having a stable structure.

[0006] The side of the first base frame is rotatably connected to a flap, which is folded above the first base frame or extended outside the first base frame. An upper scissor-type lifting frame is provided between the first base frame and the top frame to drive the top frame to descend to cover the flap and the first base frame, or to ascend away from the flap and the first base frame.

[0007] The upper scissor-type lifting frame includes a first fork and a second fork that are cross-hinged, and the 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 located on the same side of the sliding end, and the two sliding ends are slidably arranged on the top frame and the first bottom frame respectively, and a driving device is connected to at least one of the forks to drive the two forks to rotate and open and close around the central hinge;

[0016] Furthermore, the connecting rod assembly includes a third connecting rod, a fourth connecting rod and a fifth connecting rod, and a rocker rod transmission mechanism including a rocker rod, a guide block, a slider, and an elastic member. The rocker rod and the elastic member are installed on one of the two sliding ends, 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. One end of the rocker rod is pivotally connected to the sliding end, and the other end of the rocker rod is convexly provided with a pushing portion.

[0028] A method for using a linked vehicle-mounted lifting tent includes a folding process and an unfolding process. The folding process is as follows: first, a driving device is started, and the driving device drives the sliding end of one of the forks of the upper scissor-type lifting frame to move forward, so that the top frame starts to descend and the two forks gradually overlap. At the same time, the sliding end pulls the flap to rotate and fold above the first base frame through a connecting rod assembly. Finally, the top frame covers the flap and the first base frame, and the driving device stops. The unfolding process is as follows: first, the driving device is started, and the driving device drives the sliding end of one of the forks of the upper scissor-type lifting frame to move in the opposite direction, so that the top frame starts to rise and the two forks gradually separate. At the same time, the sliding end pushes the flap to rotate and extend to the outside of the first base frame through the connecting rod assembly. Finally, the upper scissor-type lifting frame supports the top frame to rise away from the flap and the first base frame. After the top frame is reset, the driving device stops. Beneficial effects

[0029] After adopting the above solution, the gain effect of the present invention is:

[0030] 1. Stability: The top frame and the first bottom frame are lifted and lowered by a scissor-type lifting frame. At the same time, the flap is linked to the folding and unfolding movement by a connecting rod assembly. In other words, the flap and the scissor-type lifting frame affect each other. As long as the flap remains stable, the tent can also remain stable during the lifting process. Even in severe weather conditions, this structure can effectively prevent the tent from being blown down or shaken by the wind.

[0031] 2. Convenience: The design of the linked flaps makes the tent easier to install and dismantle. When raising or lowering the tent, the user only needs to operate a drive device to move the flaps on both sides of the tent simultaneously, reducing the complexity and time required for operation.

[0032] 3. Safety: Since the flap is directly related to the rise and fall of the tent, this design can prevent children or pets from being accidentally caught between the tent and the flap, thereby improving safety in use.

[0033] 4. Aesthetics: The design of the linked flap can be stored when not in use, making the tent look neater and more beautiful, and improving the user's living experience. BRIEF DESCRIPTION OF THE DRAWINGS

Best Mode for Carrying Out the Invention

[0053] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] Example 1:

[0055] The present invention provides a linked vehicle-mounted lifting tent, as shown in FIG1 to FIG4 , comprising a first base frame 1 , a top frame 2 , an upper scissor-type lifting frame 3 , a flap 4 and a driving device 5 .

[0056] The side of the first base frame 1 is rotatably connected to the flap 4. A number of rotating parts 11 are provided at the rotation point of the first base frame 1 and the flap 4. Each rotating part 11 includes two L-shaped connecting parts and a pivot. One end of the two L-shaped connecting parts is respectively fixed to the first base frame 1 and the flap 4, and the other ends of the two L-shaped connecting parts are pivotally connected together through a pivot to form a herringbone structure. The flap 4 is rotated and folded above the first base frame 1 (not shown in the figure) or rotated to extend to the outside of the first base frame 1, as shown in Figures 1 to 4.

[0057] An upper scissor-type lifting frame 3 is provided between the first bottom frame 1 and the top frame 2 to drive the top frame 2 to descend to cover the flap 4 and the first bottom frame 1, or to ascend to move away from the flap 4 and the first bottom frame 1;

[0058] The upper scissor-type lifting frame 3 includes 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 are respectively pivotally connected to the top frame 2 and the first bottom frame 1. In addition, the upper end of the first fork 31 and the lower end of the second fork 32 are also located on the same side as the sliding end 33. The two sliding ends 33 are slidably arranged on the top frame 2 and the first bottom frame 1 respectively. The driving device 5 is connected to at least one of the forks to drive the two forks 31 and 32 to rotate and open and close around the central hinge.

[0059] One end of the connecting rod assembly 6 is connected to the flap 4, and the other end is connected to one of the sliding ends 33. When the driving device 5 drives the top frame 2 to descend, the sliding end 33 slides and pulls the flap 4 to rotate and fold above the first base frame 1. When the driving device 5 drives the top frame 2 to rise, the sliding end 33 slides and pushes the flap 4 to rotate and extend to the outside of the first base frame 1.

[0060] The driving device 5 drives one fork of the upper scissor-type lifting frame 3 to move, thereby driving the two forks to rotate and open and close around the central hinge. The opening and closing of the scissor-type lifting frame causes the top frame 2 to rise away from or descend to cover the first base frame 1. At the same time, since the sliding end 33 on the fork is connected to the connecting rod assembly 6, the sliding end 33 slides and pulls the flap 4 to rotate through the connecting rod assembly 6, thereby realizing the top frame 2 rising in conjunction with the opening of the flap 4 and the top frame 2 descending in conjunction with the folding of the flap 4.

[0061] The folding process is as follows: first, the driving device 5 is started, and the driving device 5 drives the sliding end 33 of one of the forks of the upper scissor-type lifting frame 3 to move forward, so that the top frame 2 starts to descend, and the two forks 31 and 32 rotate around the central hinge and gradually overlap. At the same time, the sliding end 33 pulls the flap 4 to rotate and fold above the first base frame 1 through the connecting rod assembly 6, and finally the top frame 2 covers the flap 4 and the first base frame 1, and the driving device 5 stops; the unfolding process is as follows: first, the driving device 5 is started, and the driving device 5 drives the sliding end 33 of one of the forks of the upper scissor-type lifting frame 3 to move in the opposite direction, so that the top frame 2 starts to rise, and the two forks 31 and 32 gradually separate. At the same time, the sliding end 33 pushes the flap 4 to rotate and extend to the outside of the first base frame 1 through the connecting rod assembly 6, and finally the upper scissor-type lifting frame 3 supports the top frame 2 to rise away from the flap 4 and the first base frame 1. After the top frame 2 is reset, the driving device 5 stops.

[0062] This case does not limit the number of flaps 4. It is better to design two flaps 4, and the two flaps 4 are symmetrically arranged in the same direction. One end of the connecting rod assembly 6 is connected to the sliding end 33, and the other end of the connecting rod assembly 6 is connected to the two flaps 4 respectively. When the top frame 2 rises, the two flaps 4 are linked to open, and when the top frame 2 descends, the two flaps 4 are linked to fold.

[0063] The above description is an embodiment of the vehicle-mounted lifting tent of the present invention in which only one bottom frame (first bottom frame 1) is designed. The first bottom frame 1 is installed on the vehicle. The following description is an embodiment in which a double-layer bottom frame is designed. The double-layer bottom frame can provide two upper and lower accommodating spaces, which is larger.

[0064] The present invention also includes a second chassis 8 and a lower scissor-type lifting frame 9. In this case, the first chassis 1 is not installed on the vehicle but the second chassis 8 is installed on the vehicle. The second chassis 8 is arranged below the first chassis 1, and a lower scissor-type lifting frame 9 is arranged between the second chassis 8 and the first chassis 1. The lower scissor-type lifting frame 9 has the same structure as the upper scissor-type lifting frame 3. Both 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 9 are respectively pivotally connected to the first chassis 1 and the second chassis 8, and the upper end of the first fork 31 and the lower end of the second fork 32 are also located on the sliding end 33 on the same side. The two sliding ends 33 are respectively slidably arranged on the first chassis 1 and the second chassis 8. On the second base frame 8, the two forks 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 9 are coaxially pivoted and fixed 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 9 are coaxially pivoted and slidably arranged on the first base frame 1. The two sliding ends 33 are arranged together. In this way, the upper scissor-type lifting frame 3 and the lower scissor-type lifting frame 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 is folded on the second base frame 8.

[0065] Although the above embodiment provides a case where the other end of the connecting rod assembly 6 is connected to the two sliding ends 33, namely 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 9, the other end of the connecting rod assembly 6 can also be connected to other sliding ends other than these two sliding ends (the upper end of the first fork 31 of the upper scissor-type lifting frame 3 and the lower end of the second fork 32 of the lower scissor-type lifting frame 9), and linkage can also be achieved. This embodiment only provides a preferred embodiment of the present invention and does not limit the design of this case.

[0066] The connecting rod assembly is composed of any of the following transmission mechanisms: a rack transmission mechanism, a rocker transmission mechanism, a toothed chain transmission mechanism, a pulley transmission mechanism, and a pulley transmission mechanism. Several structures of the connecting rod assembly 6 described below are not limitations of the connecting rod assembly 6 in this case. In this embodiment, as shown in Figures 5 and 6, the connecting rod assembly 6 includes a first connecting rod 64 and a second connecting rod 65, and a rack transmission mechanism including a center gear 61, an upper rack 62, and a lower rack 63; the upper rack 62 and the lower rack 63 are arranged in parallel on one side of the first chassis 1, and a center gear 61 is arranged between the upper rack 62 and the lower rack 63. The center gear 61 is pivotally connected to the side of the first chassis 1, and a dust cover 611 is also covered on the outside of the center gear 61; the upper part of the center gear 61 cooperates with the left end of the upper rack 62, and the lower part of the center gear 61 cooperates with the right end of the lower rack 63. The right end of the upper rack 62 is connected to the adjacent flap 4 through the first connecting rod 64. The left end of the lower rack 63 is connected to the other flap 4 through the second connecting rod 65, and the first connecting rod 64 and the second connecting rod 65 are both connected to the upper part of the flap 4; the right end of the lower rack 63 is also provided with a sliding groove 631 parallel to the lower rack 63, and a bolt 66 is passed through the sliding groove 631. The bolt 66 coaxially passes through 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 9. The two sliding ends 33 are connected. If the top frame 2 is to be lowered, the two sliding ends 33 are connected. The movable end 33 slides and pushes the right end of the lower rack 63 to the right. Simultaneously, the lower rack 63 engages the central gear 61 and rotates. The central gear 61 rotates and engages the upper rack 62, which moves in the opposite direction, i.e., to the left. As a result, the upper rack 62 and the lower rack 63 pull the connected flap 4 onto the first base frame 1 through the first connecting rod 64 and the second connecting rod 65, respectively. This allows the flap 4 to be automatically deployed and retracted simultaneously with the tent being raised, unfolded, or stowed, freeing hands, making it convenient to use and saving time and effort. The chute 631 is designed to delay the automatic deployment and stowage of the flap 4 for a period of time after raising or lowering. It also ensures that the top frame 2 closes onto the first base frame 1 just after the flap 4 has folded onto the first base frame 1, avoiding the situation where the top frame 2 is not closed after the flap 4 has folded and cannot be closed.

[0067] In order to make the linkage of the flap 4 smoother and more stable, the present embodiment makes the following designs:

[0068] 1. As shown in Figures 4 and 6, a heightening piece 67 is provided at the left end of the lower rack 63. The heightening piece 67 is a vertical sheet-like body. The lower end of the heightening piece 67 is fixedly connected to the left end of the lower rack 63, and the upper end of the heightening piece 67 is pivotally connected to the second connecting rod 65. The heightening piece 67 can overcome the inherent height difference between the upper rack 62 and the lower rack 63, so that the second connecting rod 65 and the first connecting rod 64 are symmetrical and have the same height. In this way, when linked, the flaps 4 on both sides can move simultaneously.

[0069] 2. As shown in Figures 1 and 4, the upper parts of the two flaps 4 are respectively provided with a first connecting bar 68 and a second connecting bar 69 protruding from the upper part, and are pivotally connected to the first connecting rod 64 and the second connecting rod 65 respectively. Specifically, the number of the first connecting bar 68 and the second connecting bar 69 is two, respectively provided on both sides of the flap 4 and protruding from the upper part. The structure of the first connecting bar 68 and the second connecting bar 69 can be the same. The first connecting bar 68 and the second connecting bar 69 are in an inverted T shape. The lower parts of the first connecting bar 68 and the second connecting bar 69 are fixed on the flap 4, and the upper parts of the first connecting bar 68 and the second connecting bar 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.

[0070] 3. As shown in FIG5 and FIG6 , a roller 661 is sleeved on the bolt 66 and is specifically arranged between the sliding end 33 and the lower rack 63 . The roller 661 can reduce the friction between the sliding end 33 and the lower rack 63 .

[0071] The present invention does not limit the number of the upper scissor-type lifting frame 3 and the lower scissor-type lifting frame 9. There can be one or more of them. This embodiment takes multiple as an example. As shown in the accompanying drawings, an upper scissor-type lifting frame 3 and a lower scissor-type lifting frame 9 are set as a group of scissor-type lifting frames. The vehicle-mounted lifting tent is provided with two groups of scissor-type lifting frames, and the other group of scissor-type lifting frames is symmetrically arranged on the other side of the first base frame 1. As shown in Figures 2, 5 and 6, a synchronization rod 10 is provided between the two groups of scissor-type lifting frames. The two ends of the synchronization rod 10 are respectively fixedly connected to the bolts 66 on both sides, and the two groups of scissor-type lifting frames are linked to open and close by the synchronization rod 10.

[0072] The drive device 5 described in the present invention is either an electric drive device 5 or a manual drive device 5 including a crank handle 51 (as shown in FIG2 ). The output end of the drive device 5 is connected to a ball screw 52. A screw nut 101 is provided on the synchronization rod 10, which is mated with the ball screw 52. The rotation of the ball screw 52, ​​through the mating screw nut 101, drives the synchronization rod 10 and the sliding ends 33 at both ends to slide. Specifically, an arched bracket 102 extends from the same side of the synchronization rod 10. The screw nut 101 is mounted on the arched bracket 102. The synchronization rod 10 is driven by the arched bracket 102 to move together with the synchronization rod 10. The arched bracket 102 can improve the smoothness of the movement of the synchronization rod 10. The above is only one embodiment of the drive device structure. The drive device structure can also adopt the same drive method as the side connecting rod assembly.

[0073] The storage process of the lifting tent in this embodiment is as follows:

[0074] First, the crank 51 is driven to rotate, and the ball screw 52 and the screw nut 101 drive the synchronization rod 10 to move right. The synchronization rod 10 moves right and drives the two sliding ends 33 connected to it to slide in the slide groove 631. At this time, the two forks 31 and 32 of the upper scissor-type lifting frame 3 are slowly merging, and the two forks of the lower scissor-type lifting frame 9 are also slowly merging, so that the top frame 2 is approaching the first bottom frame 1, and the first bottom frame 1 is approaching the second bottom frame 8. Then, when the sliding end 33 slides to the end of the slide groove 631, the sliding end 33 is moved to the bottom of the slide groove 631. The end 33 pushes the right end of the lower rack 63 to move to the right. At the same time, the lower rack 63 engages the center gear 61 to rotate, and the center gear 61 rotates to engage the upper rack 62 to move in the opposite direction, that is, to the left. As a result, the left end of the lower rack 63 pulls the connected flap 4 to be folded onto the first base frame 1 through the second connecting rod 65, and the right end of the upper rack 62 pulls the connected flap 4 to be folded onto the first base frame 1 through the first connecting rod 64. Finally, when the flap 4 is folded, the top frame 2 just covers the flap 4 and the first base frame 1, and the rotation of the crank 51 is stopped.

[0075] The unfolding process of the lifting tent in this embodiment is as follows:

[0076] First, the crank 51 is driven to rotate in the opposite direction, and the ball screw 52 and the screw nut 101 drive the synchronization rod 10 to move left. The synchronization rod 10 moves left and drives the two sliding ends 33 connected to it to slide in the slide groove 631. At this time, the two forks 31 and 32 of the upper scissor-type lifting frame 3 are slowly opened, and the two forks of the lower scissor-type lifting frame 9 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 8. Then, when the sliding end 33 slides to the initial end of the slide groove 631, , the sliding end 33 pushes the left end of the lower rack 63 to move to the left. At the same time, the lower rack 63 engages the center gear 61 to rotate, and the center gear 61 rotates to engage the upper rack 62 to move to the right. As a result, the left end of the lower rack 63 pushes the connected flap 4 to unfold on the outside of the first base frame 1 through the second connecting rod 65, and the right end of the upper rack 62 pushes the connected flap 4 to unfold on the other outside of the first base frame 1 through the first connecting rod 64. Finally, when the flap 4 is fully unfolded, the top frame 2 is just opened to the limit position, and the crank 51 stops rotating in the opposite direction.

[0077] In order to be able 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 flap 4 and the first bottom frame 1, the cover edge 21 is wrapped around the outside of the flap 4 and the first bottom frame 1, so that the top frame 2 and the first bottom frame 1 are folded into a box-like structure.

[0078] To ensure that the flap can be covered by the top frame after folding, and also to ensure that the flap begins to unfold only after the top frame rises, the stroke of the top frame rising or lowering in this case is greater than the stroke of the flap folding or unfolding.

[0079] Example 2:

[0080] The difference between the second embodiment and the first embodiment lies in the different structure of the connecting rod assembly: as shown in Figures 7 to 14 (only the structure of the upper scissor-type lifting frame 33 is shown in the figure, and the structure of the lower scissor-type lifting frame is omitted), the connecting rod assembly 6 includes a third connecting rod 74, a fourth connecting rod 75 and a fifth connecting rod 76, and a rocker transmission assembly including a rocker 70, a guide block 71, a slider 72, and an elastic member. In this embodiment, the elastic member is preferably a tension spring 73. The lower end of the second fork 32 of the upper scissor-type lifting frame 3 and the lower scissor-type lifting frame 3 are connected. A rocker arm 70 and a tension spring 73 are mounted on either of the upper ends of the first fork 31 and the lower end of the second fork 32 of the upper scissor-type lifting frame (the figures of this embodiment show that the rocker arm 70 and the tension spring 73 are mounted on the lower end of the second fork 32 of the upper scissor-type lifting frame 3). As shown in Figures 12 and 13, the rocker arm 70 is arranged horizontally, with one end of the rocker arm 70 pivotally connected to the sliding end 33, and the other end of the rocker arm 70 protrudingly provided with a push portion 701. The middle portion of the rocker arm 70 is connected to one end of the tension spring 73, and the other end of the tension spring 73 is connected to the sliding end 33.

[0081] As shown in Figures 7, 8 and 9, the guide block 71 is fixedly mounted on the middle part of the side of the first chassis 1, and one side of the guide block 71 forms a downwardly inclined lower inclined surface 711, and the other side forms an upwardly inclined upper inclined surface 712. A slider 72 is provided below the guide block 71, and the slider 72 is slidably provided on the side of the first chassis 1. One end of the slider 72 is fixedly provided with an increasing piece 67, and the increasing piece 67 is pivotally connected to the third link 74. The third link 74, the fourth link 75, and the fifth link 76 are pivotally connected in sequence. The middle part of the fourth link 75 is pivotally fixed to the side of the first chassis 1, and the other end of the fifth link 76 is pivotally connected to a flap 4. The upper end surface of the other end of the slider 72 is recessed at a position relative to the lower inclined surface 711 to form a push groove 721;

[0082] Each set of upper scissor lifts 3 is connected to a flap 4 and a connecting rod assembly 6, and the fifth connecting rod 76 of the two connecting rod assemblies 6 is pivotally connected to a flap 4;

[0083] As shown in Figures 9 to 11 and 14, when the sliding end 33 moves in the folding direction, the sliding end 33 drives the rocker arm 70 to move toward the guide block 71. The rocker arm 70 rotates downward and is stuck in the pushing groove 721 due to the abutment between the pushing portion 701 and the lower inclined surface 711 of the guide block 71, and pushes the slider 72 to slide in the folding direction through the pushing groove 721. The sliding of the slider 72 causes the third link 74 to rotate around the fourth link 75, the fourth link 75 to rotate around the middle, and the fifth link 76 to rotate around the fourth link 75, while pulling the flip plate 4 to rotate and fold above the first base frame 1, and the pushing portion 701, under the elastic force of the tension spring 73, disengages from the pushing groove 721 along the upper inclined surface 712.

[0084] When the lock body 71 is unlocked, the lock body 71 is unlocked, and the lock body 71 is unlocked, so that the lock body 71 can be unlocked. When the lock body 71 is unlocked, the lock body 71 is unlocked, and the lock body 71 is unlocked.

If the top frame 2 is to be lowered and stored, the two sliding ends 33 slide to the right and push the slide 80 to move to the right, and the slide 80 drives the lower edge of the chain 79 to move to the right. At the same time, the first sprocket 77 and the second sprocket 78 rotate, and the chain 79 engages the first sprocket 77 and the second sprocket 78 to move counterclockwise. The needle is driven, and the upper edge of the chain 79 moves to the left, so that the upper and lower edges of the chain 79 simultaneously link the first link 64 and the second link 65 to move relative to each other and pull the connected flap 4 to fold onto the first base frame 1.
