Description

Technical Field

[0001] The utility model relates to the technical field of vehicle tents, and particularly relates to a vehicle tent with an auxiliary rising structure. Background Art

[0002] For the current vehicle tent with a scissor lift, whether it is a single-layer or multi-layer one, the scissor lift between the bottom frame and the first top frame needs to bear the weight of all components above the first top frame. When the first driving mechanism located between the bottom frame and the first top frame drives the scissor lift to longitudinally extend, it needs to overcome the above-mentioned weight. Therefore, the load on the first driving mechanism is relatively heavy, and the torque used is relatively large. After long-term use, the wear of the first driving mechanism is relatively serious, which greatly reduces the service life of the driving mechanism. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a vehicle tent with an auxiliary rising structure, which overcomes the above defects, helps the first driving mechanism to drive the scissor lift to longitudinally extend, and reduces the torque used by the first driving structure.

[0004] To achieve the above purpose, the solution of the utility model is as follows:

Or, the first driving mechanism drives the two bifurcations, so that the upper ends of the two bifurcations move away from each other, and the lower ends also move away from each other, so that the first scissor lift longitudinally contracts, and further drives the first top frame to descend and fold relative to the bottom frame; the elastic assisting member is used for elastically driving the two bifurcations, so that the upper ends of the two bifurcations approach each other, and the lower ends also approach each other, to assist the first scissor lift to longitudinally extend.

[0006] Further, a first scissor lift is provided on each of the left and right sides of the chassis. One fork is a first fork, the upper end of which is pivotally connected to the rear end of the first top frame, and the lower end of which is slidably arranged at the front end of the chassis in the front-rear direction. The other fork is a second fork, the upper end of which is slidably arranged at the front end of the first top frame in the front-rear direction, and the lower end of which is pivotally connected to the rear end of the chassis. The first driving mechanism is connected to and drives the upper end of the second fork to slide close to the upper end of the first fork, so as to drive the lower end of the first fork to slide close to the lower end of the second fork, so that the first scissor lift extends longitudinally. Or, the first driving mechanism is connected to and drives the upper end of the second fork to slide away from the upper end of the first fork, so as to drive the lower end of the first fork to slide away from the lower end of the second fork, so that the first scissor lift contracts longitudinally. The elastic assist member is located on the chassis. When the lower end of the first fork slides close to the lower end of the second fork, the elastic assist member elastically pushes or elastically pulls the lower end of the first fork to slide close to the lower end of the second fork.

[0007] Further, chutes are respectively arranged on the left and right sides of the chassis and extend in the front-rear direction. The lower end of the first fork is located at the front end inside the chute, and the lower end of the second fork is pivotally connected to the rear end inside the chute.

Mounting seats are respectively arranged at both ends of the telescopic sleeve. One of the mounting seats is connected to the lower end of the first fork, and the other mounting seat is fixed to the chute through a fixing plate. A compression spring is arranged inside the telescopic sleeve, and both ends of the compression spring are respectively connected to the mounting seats at both ends of the telescopic sleeve.

The second scissor lift is arranged between the first top frame and the second top frame and includes two forks that are cross-hinged. The upper ends of the two forks are arranged on the second top frame, and the lower ends of the two forks are arranged on the first top frame. The second driving mechanism is used to drive one fork so that the upper end and the lower end of this fork are respectively close to the upper end and the lower end of the other fork, so that the second scissor lift extends longitudinally, and then drives the second top frame to rise and unfold relative to the first top frame. Or the second driving mechanism drives one fork so that the upper end and the lower end of this fork are respectively away from the upper end and the lower end of the other fork, so that the second scissor lift contracts longitudinally, and then drives the second top frame to descend and fold relative to the first top frame.

[0010] Further, it further includes a second top frame and a second scissor lift. The second top frame is located above the first top frame. The second scissor lift is arranged between the first top frame and the second top frame. The second scissor lift includes two bifurcations that are cross-hinged. The upper ends of the two bifurcations are connected to the second top frame. The lower ends of the two bifurcations are respectively hinged to the upper ends of the two bifurcations of the first scissor lift, and a hinge shaft A and a hinge shaft B are formed at the hinge joints. When the first driving mechanism drives the first scissor lift to longitudinally extend, it can drive the hinge shaft A and the hinge shaft B to approach each other, so as to drive the second scissor lift to longitudinally extend, and the first top frame and the second top frame rise and unfold relative to the bottom frame. When the first driving mechanism drives the first scissor lift to longitudinally contract, it can drive the hinge shaft A and the hinge shaft B to move away from each other, so as to drive the second scissor lift to longitudinally contract, and the first top frame and the second top frame descend and fold relative to the bottom frame.

[0011] Further, an elastic assisting member is arranged between the hinge shaft A and the hinge shaft B. Its two ends are respectively connected to the hinge shaft A and the hinge shaft B. The elastic assisting member is used to elastically pull the hinge shaft A and the hinge shaft B to approach each other, so that the upper ends of the two bifurcations of the first scissor lift approach each other, and the lower ends also approach each other.

Specific embodiments

[0021] The following will describe the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0022] As Figures 1 to 4 shown, the present utility model provides a vehicle tent with an auxiliary rising structure, including a chassis 10, a first top frame 20, a first scissor lift 30, a first driving mechanism, and an elastic assist member 40;

[0023] Among them, the chassis 10 is used to be installed on an automobile; the first top frame 20 is located above the chassis 10; the first scissor lift 30 is arranged between the chassis 10 and the first top frame 20, and it includes two crossed and hinged forks. The upper ends of the two forks are arranged on the first top frame 20, and the lower ends of the two forks are arranged on the chassis 10; the first driving mechanism is used to drive the two forks so that the upper ends of the two forks approach each other, and the lower ends also approach each other, so that the first scissor lift 30 extends longitudinally, thereby driving the first top frame 20 to rise and unfold relative to the chassis 10, or the first driving mechanism drives the two forks so that the upper ends of the two forks move away from each other, and the lower ends also move away from each other, so that the first scissor lift 30 contracts longitudinally, thereby driving the first top frame 20 to descend and fold relative to the chassis 10; the elastic assist member 40 is used to elastically drive the two forks so that the upper ends of the two forks approach each other, and the lower ends also approach each other, to assist the first scissor lift 30 to extend longitudinally.

[0024] The present utility model includes an elastic assist member 40. By elastically driving the two forks through the elastic assist member 40, the upper ends of the two forks approach each other, and the lower ends also approach each other, to assist the first scissor lift 30 to extend longitudinally. Therefore, the elastic assist member 40 helps the first driving mechanism drive the first scissor lift 30 to extend longitudinally, reduces the torque used by the first driving structure, helps the first driving mechanism overcome resistance, reduces the wear of the first driving mechanism, and increases the service life of the first driving mechanism.

[0025] Specifically, a first scissor lift 30 is provided on each of the left and right sides of the chassis 10. One fork is the first fork 31, the upper end of which is pivotally connected to the rear end of the first top frame 20, and the lower end of which is slidably arranged at the front end of the chassis 10 in the front and rear directions. The other fork is the second fork 32, the upper end of which is slidably arranged at the front end of the first top frame 20 in the front and rear directions, and the lower end of which is pivotally connected to the rear end of the chassis 10. The first driving mechanism is connected to and drives the upper end of the second fork 32 to slide close to the upper end of the first fork 31, so as to drive the lower end of the first fork 31 to slide close to the lower end of the second fork 32, so that the first scissor lift 30 extends longitudinally. Or, the first driving mechanism is connected to and drives the upper end of the second fork 32 to slide away from the upper end of the first fork 31, so as to drive the lower end of the first fork 31 to slide away from the lower end of the second fork 32, so that the first scissor lift 30 contracts longitudinally. The elastic assisting member 40 is located on the chassis 10. When the lower end of the first fork 31 slides close to the lower end of the second fork 32, the elastic assisting member 40 elastically pushes or elastically pulls the lower end of the first fork 31 to slide close to the lower end of the second fork 32, reducing the torque used by the first driving structure, helping the first driving mechanism to overcome resistance, reducing the wear of the first driving mechanism, and increasing the service life of the first driving mechanism. Specifically, the first driving mechanism is preferably a linear lead screw, and the power end of the linear lead screw is connected to and drives the upper end of the second fork 32.

[0026] Further, sliding grooves 11 are respectively arranged on the left and right sides of the chassis 10 and extend in the front and rear directions. The lower end of the first fork 31 is located at the front end inside the sliding groove 11, and the lower end of the second fork 32 is pivotally connected to the rear end inside the sliding groove 11. Specifically, the lower end of the first fork 31 slides along the extending direction of the sliding groove 11 to ensure the stability of the sliding of the lower end of the first fork 31.

[0027] Specifically, the elastic assisting member 40 is arranged inside the sliding groove 11. Preferably, the elastic assisting member 40 includes at least one telescopic sleeve 41. Mounting seats 42 are respectively arranged at both ends of the telescopic sleeve 41. One of the mounting seats 42 is connected to the lower end of the first fork 31, and the other mounting seat 42 is fixed to the sliding groove 11 through a fixing plate 44. A compression spring 43 is arranged inside the telescopic sleeve 41, and both ends of the compression spring 43 are respectively connected to the mounting seats 42 at both ends of the telescopic sleeve 41. Specifically, there are three compression springs 43, and there are also three telescopic sleeves 41.

[0028] In a specific embodiment, the elastic assisting member 40 is located between the front wall of the sliding groove 11 and the lower end of the first fork 31. The elastic assisting member 40 elastically pushes against the lower end of the first fork 31, so that when the lower end of the first fork 31 slides closer to the lower end of the second fork 32, the elastic assisting member 40 assists the lower end of the first fork 31 to slide towards the lower end of the second fork 32. At this time, the compression spring 43 gradually extends from the compressed state, and the mounting seat 42 connected to the lower end of the first fork 31 is pushed by the compression spring 43 to move, so that the distance between the two mounting seats 42 gradually increases, and further the length of the telescopic sleeve 41 gradually increases until the sliding of the lower end of the first fork 31 stops. It can be understood that when the sliding of the lower end of the first fork 31 stops, the compression spring 43 is still in the compressed state and has not completely returned to the normal state. The normal state refers to the length of the compression spring 43 without external compression or pulling force, and it can play a role in assisting the first scissor lift 30 to support the first top frame 20;

[0029] In another specific embodiment, the elastic assisting member 40 is located at the rear end of the sliding groove 11 and on the front side of the lower end of the second fork 32. The elastic assisting member 40 elastically pulls the lower end of the first fork 31, so that when the lower end of the first fork 31 slides closer to the lower end of the second fork 32, the elastic assisting member 40 assists the lower end of the first fork 31 to slide towards the lower end of the second fork 32. At this time, the compression spring 43 gradually shortens from the stretched state, and the compression spring 43 pulls the mounting seat 42 connected to the lower end of the first fork 31 to move, so that the distance between the two mounting seats 42 gradually decreases, and further the length of the telescopic sleeve 41 gradually shortens until the sliding of the lower end of the first fork 31 stops. It can be understood that when the sliding of the lower end of the first fork 31 stops, the compression spring 43 is still in the stretched state and has not returned to the normal state, and it can play a role in assisting the first scissor lift 30 to support the first top frame 20;

[0030] Further, it further includes a second top frame 50, a second scissor lift, and a second drive mechanism; the second top frame 50 is located above the first top frame 20, and the second scissor lift 60 is disposed between the first top frame 20 and the second top frame 50, and it includes two bifurcations that are cross-hinged, the upper ends of the two bifurcations are disposed on the second top frame 50, and the lower ends of the two bifurcations are disposed on the first top frame 20; the second drive mechanism is used to drive one bifurcation so that the upper end and the lower end of this bifurcation are respectively close to the upper end and the lower end of the other bifurcation, so that the second scissor lift 60 extends longitudinally, and further drives the second top frame 50 to rise and unfold relative to the first top frame 20, or the second drive mechanism drives one bifurcation so that the upper end and the lower end of this bifurcation are respectively away from the upper end and the lower end of the other bifurcation, so that the second scissor lift 60 contracts longitudinally, and further drives the second top frame 50 to descend and fold relative to the first top frame 20; specifically, the second drive mechanism is preferably a linear lead screw, and the power end of the linear lead screw is connected to and drives one bifurcation; specifically, a second scissor lift 60 is disposed on both the left and right sides of the first top frame 20.

[0031] As Figures 5 to 6 shown, in another embodiment, it further includes a second top frame 50 and a second scissor lift 60. The second top frame 50 is located above the first top frame 20, and the second scissor lift 60 is disposed between the first top frame 20 and the second top frame 50. The second scissor lift 60 includes two bifurcations that are cross-hinged. The upper ends of the two bifurcations are connected to the second top frame 50, and the lower ends of the two bifurcations are respectively hinged to the upper ends of the two bifurcations of the first scissor lift 30, and a hinge shaft A70 and a hinge shaft B80 are formed at the hinge joints; when the first drive mechanism drives the first scissor lift 30 to extend longitudinally, it can drive the hinge shaft A70 and the hinge shaft B80 to approach each other, so as to drive the second scissor lift 60 to extend longitudinally, and make the first top frame 20 and the second top frame 50 rise and unfold relative to the bottom frame 10. When the first drive mechanism drives the first scissor lift 30 to contract longitudinally, it can drive the hinge shaft A70 and the hinge shaft B80 to move away from each other, so as to drive the second scissor lift 60 to contract longitudinally, and make the first top frame 20 and the second top frame 50 descend and fold relative to the bottom frame 10;

[0032] Specifically, an elastic assist member 40 is disposed between the hinge shaft A70 and the hinge shaft B80, and its two ends are respectively connected to the hinge shaft A70 and the hinge shaft B80. The elastic assist member 40 is used to elastically pull the hinge shaft A70 and the hinge shaft B80 to approach each other, so that the upper ends of the two bifurcations of the first scissor lift 30 approach each other, and the lower ends also approach each other, and at the same time, the upper ends of the two bifurcations of the second scissor lift 60 approach each other, and the lower ends also approach each other, so as to assist the first scissor lift 30 to drive the second scissor lift 60 to extend longitudinally;

[0033] Specifically, in this embodiment, the elastic assisting member 40 includes a compression spring 43 and a telescopic sleeve 41. The telescopic sleeve 41 is sleeved on the compression spring 43. The compression spring 43 sleeved with the telescopic sleeve 41 is located between the hinge shaft A 70 and the hinge shaft B 80, and both ends of the compression spring 43 are respectively hooked on the hinge shaft A 70 and the hinge shaft B 80.
