Description

Technical Field

[0001] The invention relates to the field of automobile roof mechanisms, in particular to a labor-saving lifting roof for a vehicle. Background Art

[0002] At present, people's demands for automobile functions are becoming increasingly diversified. In some models, soft-lift roofs are designed to increase usage functions and expand space. The design of soft-lift roofs should take into account safety, stability and convenience. The convenience design is reflected in the following requirements: the space occupied by the lifting structure in the car, the energy consumed by the lifting and the energy occupied by the car, and the reliability of the lifting structure in actual outdoor and driving scenarios.

[0003] The invention patent with Chinese patent application number CN201721325409.6 discloses an RV tent, including a tent frame fixed on the roof of the RV and a tent cloth covered on the tent frame, the tent frame including a base and a top cover, the base and the top cover are connected by a connecting rod mechanism arranged at one end of the base, the base is connected to the RV roof, and also includes a support rod arranged at the other end of the base, the bottom end of the support rod is hinged to the base through a rotating shaft, and the top end of the support rod is hung with the top cover through a hook arranged on the top cover.

[0004] The design of the active lifting mechanism in the existing technology has a low utilization rate of power output, which leads to greater requirements for the thrust and stroke of the push rod, which makes the self-locking force of the push rod itself very large. On the one hand, it increases energy consumption and occupies more space; on the other hand, when the power is suddenly cut off, manual operation is more laborious, affecting use; in addition, the base and the top cover are directly rigidly connected through a connecting rod mechanism, which makes the related components directly rigidly connected more easily damaged due to hard pulling during bumpy driving, and the reliability is insufficient. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies in the prior art and provide a labor-saving lifting canopy for a vehicle. The power is provided by a power source, and an inclined lifting component and a parallel conversion component are used to make the canopy transition between the two states of triangular support lifting movement and lever lifting movement. The overall structural design is compact, and the synchronous lifting component is used to achieve more labor-saving folding and lifting of the canopy. The tarpaulin will not get stuck and damaged, and the thrust requirement for the power source is smaller than that of the prior art solution. Therefore, the self-locking force of the power source itself is smaller, and manual operation is also more labor-saving.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A labor-saving lifting canopy for a vehicle, comprising a canopy main frame arranged on a vehicle roof and a tarpaulin wrapped on the main frame, the main frame comprising an upper mounting frame and a lower mounting frame for mounting the upper and lower parts of the tarpaulin respectively, the lower mounting frame being mounted on the vehicle roof; a group of synchronous lifting components are symmetrically arranged at one end of the upper mounting frame and the lower mounting frame, a group of inclined lifting components are symmetrically arranged at one side of the lower mounting frame away from the synchronous lifting components, and a power source for driving the inclined lifting components to reciprocate, characterized in that the power source is mounted on the lower mounting frame, and the inclined lifting components comprise:

[0008] A first connecting rod, wherein a parallel conversion assembly is provided below the upper mounting frame near the end, the upper end of the first connecting rod is reciprocatingly slidably mounted on the parallel conversion assembly, and the lower end of the first connecting rod is hinged to the power output end of the power source;

[0009] And a second connecting rod, the lower end of which is hinged to the lower mounting frame, and the upper end of which is hinged to the lower part of the first connecting rod and a roller is installed on the hinge shaft, so that the second connecting rod, the first connecting rod and the lower mounting frame can form a triangular structure when the upper mounting frame is fully opened or folded relative to the lower mounting frame, and in the folded state, the roller is the highest fulcrum of the inclined lifting assembly to support the upper mounting frame.

[0010] The power source drives the lower end of the first connecting rod to reciprocate horizontally, so as to at least realize the opening action of the upper mounting frame.

[0011] As an improvement, the power source is located between the parallel conversion assembly and the synchronous lifting assembly in the horizontal direction, and the position where the power source is hingedly connected to the first connecting rod is always located between the hinge point at the lower end of the second connecting rod and the synchronous lifting assembly.

[0012] The power source is located between the parallel conversion assembly and the synchronous lifting assembly in the horizontal direction, so that the roller is arranged close to the middle of the upper mounting frame, so that the process before the upper mounting frame is lifted to the lever action state is relatively labor-saving. At the same time, the position where the power source is hingedly connected to the first connecting rod is always located between the hinge point at the lower end of the second connecting rod and the synchronous lifting assembly, so that the entire inclined lifting assembly is firm and reliable after folding, and will not be shaken or pulled and damaged due to bumpy driving conditions. At the same time, in conjunction with the parallel conversion assembly, it provides the entire upper mounting frame with a rotating floating space even when driving on bumpy roads, and there will be no hard pulling damage to other directly rigidly connected components.

[0013] As an improvement, a mounting seat is also provided on the lower mounting frame, and the lower ends of the power source, the first connecting rod and the second connecting rod are all mounted on the mounting seat. A guide groove is also provided on the mounting seat, and a guide wheel that is slidably adapted to the guide groove is installed on the lower end of the first connecting rod.

[0014] As an improvement, the hinge point between the first link and the second link is farther away from the upper end of the first link than from the lower end of the first link, and is the same distance from the lower end of the first link as that of the second link, adopting an isosceles triangle structure with compact space and high stability, and capable of lifting larger loads.

[0015] As an improvement, the first connecting rod comprises a force distribution section, a transition section and a support section with an integrated smooth transition arrangement, the force distribution section is linear, and its lower end is hinged to the power output end of the power source, and the end of the support section away from the transition section is linear and is movably connected to the parallel conversion assembly by means of a slide rail slider;

[0016] The hinge point of the second connecting rod and the first connecting rod is located at the smooth transition between the force distribution section and the transition section. The force distribution section and the inner side of the transition section are arranged at an angle α, 90°<α<180°.

[0017] The first connecting rod in the present invention adopts an integrated structure and combines multiple sections with different shapes. On the one hand, when realizing the lever effect, it takes up less space when folded, is convenient and labor-saving to drive, and avoids interference problems during lifting and lowering; on the other hand, in the process of folding and unfolding the tarpaulin, it plays a follow-up flattening role on the tarpaulin, and the tarpaulin will not be stuck or damaged.

[0018] As an improvement, the transition section and the support section are both arc-shaped and the arc directions are arranged facing each other. The arc opening near the upper end of the support section is upward and the suspended end of the support section is straight. After being fully folded, it can be fully in contact with the lower mounting frame, which is firm and reliable.

[0019] As an improvement, the total length of the support section and the transition section is 3-5 times the length of the force-dividing section, which saves more effort and is also conducive to the synchronous combing of the tarpaulin during folding and unfolding, ensuring smooth operation and no scratches on the tarpaulin.

[0020] As an improvement, the parallel conversion component includes:

[0021] A translation member, a slide rail is installed below the translation member and is slidably connected with a slider installed on the upper end of the first connecting rod;

[0022] and a swinging member, wherein both sides of the translation member are rotatably connected to a swinging member respectively, and the upper end of the swinging member is rotatably connected to the upper mounting frame;

[0023] The translation member remains parallel to the upper mounting frame during the movement.

[0024] As an improvement, the length of the swinging member is smaller than the length of the translatory member.

[0025] As an improvement, the upper mounting frame and the lower mounting frame are in the shape of a rectangular frame. After the upper mounting frame and the lower mounting frame are completely folded, the lower plane of the upper end of the first connecting rod is completely in contact with and abuts against the lower mounting frame, and the distance between it and the upper mounting frame is the same as the distance between the roller and the lower mounting frame.

[0026] The beneficial effects of the present invention are:

[0027] (1) The present invention forms a triangular structure through the force distribution section of the inclined lifting assembly and the second connecting rod, and arranges a roller at the top of the triangular structure. The upper mounting frame is lifted by the roller triangle, thereby reducing the power demand, and the contact point between the inclined lifting assembly and the upper mounting frame is changed, that is, the upper mounting frame is pushed by the roller and then pushed by one end of the first connecting rod, so that the end of the first connecting rod follows the folding parallel conversion mechanism and applies force to lift the upper mounting frame, that is, the force application part of the overall mechanism on the upper mounting frame is changed from the middle position to the end. During the whole lifting process, the thrust requirement of the electric push rod is smaller than that of the existing technical solution, and thus a model with smaller self-locking force can be selected, thereby solving the technical problem that the electric push rod in the prior art uses a large self-locking force, which makes manual folding difficult and inconvenient to operate.

[0028] (2) The present invention uses a parallel conversion assembly to unfold together with the first connecting rod when the upper mounting frame and the lower mounting frame are in a fully folded state, so as to compensate for the space between the upper end of the first connecting rod and the upper mounting frame, so that after folding, both ends of the mounting frame can play a good horizontal supporting and fixing role, thereby maintaining stability and reliability during driving.

[0029] (3) The present invention reduces the interference between the inclined lifting movement and the lower mounting member through the arc design of the transition section and the support end, and also increases the synchronous arrangement of the tarpaulin. At the same time, it matches the sliding matching installation of the parallel conversion component, simplifies the structure and design of the lower mounting frame, and reduces the space occupied.

[0030] (4) The present invention uses the parallel conversion assembly to always maintain a folded state during the lever action process, so that when a jam or vibration occurs during the operation, the parallel conversion assembly provides a good buffering effect to avoid hard pulling damage between other directly rigidly connected components.

[0031] In summary, the present invention has the effects of reducing the space occupied by the overall structure in the vehicle, saving the energy consumed by lifting and the energy occupied by the vehicle, reducing the demand for power source output, and buffering the impact caused by vibration and jamming, thereby improving the smoothness of opening and closing the canopy, and greatly reducing the force required when the canopy needs to be closed manually, so that the canopy will be more adaptable to different outdoor working environments.

[0042] Embodiment 1

[0043] like Figure 1-3 As shown, this embodiment provides a labor-saving lifting canopy for a vehicle, comprising a canopy main frame I arranged on the roof and a tarpaulin II covered on the main frame, the main frame I comprising an upper mounting frame 1 and a lower mounting frame 2 for mounting the upper and lower parts of the tarpaulin II respectively, the lower mounting frame 2 being mounted on the roof; a group of synchronous lifting components 3 are symmetrically arranged at one end of the upper mounting frame 1 and the lower mounting frame 2, respectively, a group of inclined lifting components 4 and a power source for driving the inclined lifting components 4 to reciprocate are symmetrically arranged at the side of the lower mounting frame 2 away from the synchronous lifting components 3, respectively, the power source is mounted on the lower mounting frame 2, and the inclined lifting components 4 include:

[0044] A first connecting rod 41, a parallel conversion assembly 5 is provided below the upper mounting frame 1 near the end, the upper end of the first connecting rod 41 is reciprocatingly slidably mounted on the parallel conversion assembly 5, and the lower end of the first connecting rod 41 is hinged to the power output end of the power source; and

[0045] The second connecting rod 42, the lower end of the second connecting rod 42 is hinged to the lower mounting frame 2, and the upper end thereof is hinged to the lower part of the first connecting rod 41 and a roller 43 is installed on the hinge axis, so that the second connecting rod 42, the first connecting rod 41 and the lower mounting frame 2 can form a triangular structure when the upper mounting frame 1 is fully opened or folded relative to the lower mounting frame 2, and in the folded state, the roller 43 is the highest fulcrum of the inclined lifting assembly 4 to support the upper mounting frame 1.

[0046] Among them, the synchronous lifting component 3 is a prior art, and its specific structure is not described in detail.

[0047] It should be noted that the first connecting rod 41 is located between the second connecting rod 42 and the synchronous lifting assembly 3 .

[0048] The power source drives the lower end of the first connecting rod 41 to reciprocate horizontally, so as to at least realize the opening action of the canopy upper mounting frame 1.

[0049] It should be noted that, in the present embodiment, the power source preferably adopts a short-stroke pen-type push rod assembly to meet the lifting requirements, and the power output end of the short-stroke pen-type push rod assembly is hinged to the first connecting rod 41 .

[0050] It should be noted that the upper mounting frame 1 performs an oblique lifting motion relative to the lower mounting frame 2 through the synchronous lifting assembly 3, the power source, the oblique lifting assembly 4 and the parallel conversion assembly 5.

[0051] like Figure 2 and Figure 4 As shown, further, the power source is located between the parallel conversion assembly 5 and the synchronous lifting assembly 3 in the horizontal direction, and the position where the power source is hingedly connected to the first connecting rod 41 is always located between the hinge point at the lower end of the second connecting rod 42 and the synchronous lifting assembly 3.

[0052] It should be noted that the power source is located between the parallel conversion assembly 5 and the synchronous lifting assembly 3 in the horizontal direction, so that the roller 43 is arranged close to the middle of the upper mounting frame 1, so that the process of lifting the upper mounting frame 1 to the lever action state is relatively labor-saving. At the same time, the position where the power source is hingedly connected to the first connecting rod 41 is always located between the hinge point at the lower end of the second connecting rod 42 and the synchronous lifting assembly 3, so that the entire inclined lifting assembly 4 is firm and reliable after folding, and will not be shaken or pulled and damaged due to bumpy driving conditions. At the same time, in conjunction with the parallel conversion assembly 5, even when driving on bumpy roads, it provides the entire upper mounting frame 1 with a rotating floating space, and there will be no hard pulling damage to other directly rigidly connected components.

[0053] Furthermore, a mounting seat 22 is provided on the lower mounting frame 2, and the lower ends of the power source, the first connecting rod 41 and the second connecting rod 42 are all mounted on the mounting seat 22. A guide groove 221 is also provided on the mounting seat 22, and a guide wheel 222 slidably adapted to the guide groove 221 is installed at the lower end of the first connecting rod 41.

[0054] like Figure 5 and Figure 6 As shown, further, the dimension of the hinge point between the first link 41 and the second link 42 from the upper end of the first link 41 is greater than the dimension from the lower end of the first link 41 , and the dimension from the lower end of the first link 41 is the same as the dimension of the second link 42 .

[0055] Furthermore, the first connecting rod 41 includes a force distribution section 411, a transition section 412 and a support section 413 which are arranged in an integrated smooth transition. The force distribution section 411 is linear, and its lower end is hinged to the power output end of the power source. The end of the support section 413 away from the transition section 412 is linear and is movably connected to the parallel conversion assembly 5 by means of a slide rail 511 and a slider 414.

[0056] The hinge point of the second connecting rod 42 and the first connecting rod 41 is located at the smooth transition between the force distribution section 411 and the transition section 412. The force distribution section 411 and the inner side of the transition section 412 are arranged at an angle α, 90°<α<180°.

[0057] It should be noted that, in the present embodiment, the angle α between the inner side of the force distribution section 411 and the transition section 412 is 150°, which is designed to save effort during lifting and to be able to be folded to the smallest state after folding.

[0058] Furthermore, the transition section 412 and the support section 413 are both arc-shaped and arranged in arc directions facing each other, and the arc opening near the upper end of the support section 413 faces upward.

[0059] It should be noted that, in this embodiment, by setting the arc-shaped opening of the support end to face upward and the arc-shaped opening of the transition section 412 to face downward, the interference of the first connecting rod 41 on the upper mounting frame 1 and the lower mounting frame 2 during movement is reduced, and it is more conducive to the synchronous arrangement of the tarpaulin, avoiding jamming and damage, which affects the operation.

[0060] It is also necessary to explain that the suspended end of the support section 413 is in a straight line shape, and after being fully folded, it can be in full contact with the lower mounting frame 2, which is firm and reliable.

[0061] Furthermore, the total length of the support section 413 and the transition section 412 is 3-5 times the length of the force distribution section 411 .

[0062] It should be noted that, in the present embodiment, the length of the transition section 412 is greater than the length of the force distribution section 411 , and the length of the support section 413 is greater than the length of the force distribution section 411 .

[0063] It should be noted that, in this embodiment, the total length of the support section 413 and the transition section 412 is 4.5 times the length of the force distribution section 411 .

[0064] Embodiment 2

[0065] like Figure 3 , Figure 4 and Figure 7 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment is different from the first embodiment in that the parallel conversion assembly 5 in this embodiment includes:

[0066] A translation member 51, a slide rail 511 is installed below the translation member 51, and the slide rail 511 is slidably connected with the slider 414 installed on the upper end of the first connecting rod 41; and

[0067] Swinging member 52, both sides of the translation member 51 are rotatably connected to a swinging member 52, and the upper end of the swinging member 52 is rotatably connected to the upper mounting frame 1;

[0068] The translation member 51 remains parallel to the upper mounting frame 1 during the movement.

[0069] It should be noted that the translation member 51 and the swing members 52 installed on both sides form a parallel four-bar linkage with the upper mounting frame 1 .

[0070] Furthermore, the length of the swinging member 52 is shorter than that of the translatory member 51 .

[0071] It should be noted that, in this embodiment, the length of the swing member 52 is one quarter of the length of the translation member 51 .

[0072] like Figure 2 and Figure 4 As shown, further, the upper mounting frame 1 and the lower mounting frame 2 are in the shape of a rectangular frame. After the upper mounting frame 1 and the lower mounting frame 2 are completely folded, the lower plane 415 of the upper end portion of the first connecting rod 41 is completely in contact with and abuts against the lower mounting frame 2, and the distance between it and the upper mounting frame 1 is the same as the distance between the roller 43 and the lower mounting frame 2.

[0073] It should be noted that, in the present embodiment, a group of synchronous lifting components 3, a power source, an inclined lifting component 4 and a parallel conversion component 5 are arranged on two rectangular support plates parallel to each other.

[0074] It should be noted that the mounting frame, the first connecting rod 41, the second connecting rod 42, the translation member 51, and the swing member 52 all adopt a lightweight structural design. The lightweight structure includes a pair of welded L-shaped plates, and a plurality of through openings are opened on the L-shaped plates to reduce the dead weight of the inclined lifting assembly 4 and the parallel conversion assembly 5, thereby reducing the output requirement of the inclined lifting movement.

[0075] Working steps

[0076] The working step stage of this embodiment is the inclined lifting movement, which is divided into a first movement stage and a second movement stage;

[0077] In the first movement stage, the triangular lifting stage, the force exerted on the upper mounting frame 1 by the upper end of the first connecting rod 41 is completely removed, and the force distribution section 411 of the first connecting rod 41, the second connecting rod 42 and the lower mounting frame 2 cooperate with each other to form a triangular structure. When the push rod assembly outputs power, the angle between the force distribution section 411 and the second connecting rod 42 decreases, and the distance between the contact point between the force distribution rod and the second connecting rod 42 and the lower mounting frame 2 increases. At the same time, the upper mounting frame 1 is lifted through the contact between the roller 43 and the upper mounting frame 1.

[0078] The second movement stage is the lever lifting stage. In this movement stage, the upper mounting frame 1 is separated from the roller 43, and the hinge point of the first connecting rod 41 and the second connecting rod 42 is used as a fulcrum. The force distribution section 411 is subjected to force, and the first connecting rod 41 rotates to lift the parallel conversion assembly 5 and the upper mounting frame 1. During the lever lifting stage, the parallel conversion assembly 5 always remains in a folded state, but if it gets stuck or vibrates during operation, the parallel conversion assembly 5 provides a good buffering effect to avoid hard pulling damage between other directly rigidly connected components.

[0079] During the folding process, when the roller 43 at the hinged joint of the first connecting rod 41 and the second connecting rod 42 contacts the upper mounting frame 1, the lever action state is completely converted to the triangular structure support state, the driving force of the electric push rod on the first connecting rod 41 is completely released, and the connecting end of the first connecting rod 31 and the parallel conversion assembly 5 abuts against the lower mounting frame 2, so that the force at the end of the first connecting rod 31 is completely separated from the upper mounting frame 1. At this time, the entire upper mounting frame 1 is supported by the roller 43 of the triangular structure;

[0080] Since the supporting position of the triangular structure is close to the middle of the upper mounting frame 1 after folding, when lifting is required, only a small thrust of the electric push rod is needed to first push the triangular mechanism to lift the upper mounting frame 1 as a whole to the roller 43 where it is separated from the triangular mechanism, and then use the lever effect to make the end of the first connecting rod 41 follow the folding parallel conversion component 5 and apply force to lift the upper mounting frame 1, that is, the force application part of the overall mechanism on the upper mounting frame 1 is changed from the middle position to the end. The thrust requirement of the electric push rod during the whole lifting process is smaller than that of the existing technical solution, and thus a model with smaller self-locking force can be selected. On the other hand, when the power is accidentally cut off, manual folding only requires a small force (20-30KG) to realize the folding of the entire canopy, which is very labor-saving.

[0081] In addition, when in the fully folded state, the parallel conversion assembly 5 and the first connecting rod 41 are unfolded to compensate for the space between the upper end of the first connecting rod 41 and the upper mounting frame 1, so that after folding, both ends of the mounting frame can play a good horizontal supporting and fixing role to maintain stability and reliability during driving.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
