As living standards improve, people's needs for vehicles are also changing, especially the demand for vehicle space, in order to improve passenger comfort and storage capacity. The interior space of traditional cars is fixed due to the layout of the exterior and internal structure. To solve the problem of vehicle interior space, some vehicles now use adjustable roofs to adjust the size of the interior space.

[0003] The existing vehicle roof lifting mechanism has a curtain around the roof, which is connected to the vehicle body. After the roof is raised, it forms a closed space with the curtain and the vehicle body. A lifter is connected between the roof and the vehicle body.

Detailed Implementation

[0035] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0036] A preferred embodiment of a roof lifting mechanism of this application, such as... Figures 1 to 7 As shown, the roof lifting mechanism 3 includes a first lifting component 3a and a second lifting component 3b, which are used to drive the roof 2 of the vehicle to rise and fall along the vehicle height direction Z.

[0037] The first lifting assembly 3a includes a first scissor lift unit 31 and a first drive unit 32. The first drive unit 32 is connected to the first scissor lift unit 31 and drives the first scissor lift unit 31 to move up and down along the vehicle height direction Z. The top of the first scissor lift unit 31 is connected to the roof 2, and the bottom of the first scissor lift unit 31 is connected to the roof 1. When the first scissor lift unit 31 moves up and down along the vehicle height direction Z, it can drive the roof 2 to move up and down synchronously.

[0038] The second lifting assembly 3b includes a second scissor lift unit 33 and a second drive unit 34. The second drive unit 34 is connected to the second scissor lift unit 33 and drives the second scissor lift unit 33 to move up and down along the vehicle height direction Z. The top of the second scissor lift unit 33 is connected to the roof 2, and the bottom of the second scissor lift unit 33 is connected to the roof 1. When the second scissor lift unit 33 moves up and down along the vehicle height direction Z, it can drive the roof 2 to move up and down synchronously.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the first scissor lift unit 31 and the second scissor lift unit 33 are spaced apart along the vehicle length direction X, and the first drive unit 32 and the second drive unit 34 are spaced apart along the vehicle height direction Z. The first scissor lift unit 31 and the second scissor lift unit 33 cooperate with each other to synchronously drive the top cover 2 to rise and fall, adjust the height of the top cover 2, and thus adjust the space inside the vehicle in the height direction.

[0040] When the first scissor lift unit 31 and the second scissor lift unit 33 lower the roof 2 to the lowest position, the first scissor lift unit 31 and the second scissor lift unit 33 will inevitably occupy a certain space in the vehicle height direction Z. By setting the first drive unit 32 and the second drive unit 34 at intervals along the vehicle height direction Z, the space occupied by the first scissor lift unit 31 and the second scissor lift unit 33 in the vehicle height direction Z can be used to simultaneously assemble the first drive unit 32 and the second drive unit 34. There is no need to set the first scissor lift unit 31 and the second scissor lift unit 33 along the vehicle length direction X or the vehicle width direction Y, thereby reducing the vehicle space occupied by the entire roof lifting mechanism 3 and improving the space utilization rate of the vehicle.

[0041] Optionally, along the vehicle length direction X, the first drive unit 32 and the second drive unit 34 are both located between the first scissor lift unit 31 and the second scissor lift unit 33; along the vehicle height direction Z, the projection area of ​​the first drive unit 32 and the projection area of ​​the second drive unit 34 partially overlap.

[0042] like Figure 1 , Figure 2 and Figure 3As shown, the first drive unit 32 and the second drive unit 34 are both disposed between the first scissor lift unit 31 and the second scissor lift unit 33, and their projection areas partially overlap, so that the first drive unit 32 and the second drive unit 34 have a partially overlapping area along the vehicle length direction X, which can reduce the total space occupied by the first drive unit 32 and the second drive unit 34 along the vehicle length direction X and improve the space utilization of the vehicle.

[0043] Optionally, the first drive unit 32 includes a first electric support rod 321 and a first connecting seat 322 arranged sequentially along the vehicle length direction X. The first connecting seat 322 is fixedly connected to the first electric support rod 321 and the second scissor lift unit 33. The drive end of the first electric support rod 321 is drivenly connected to the first scissor lift unit 31. The second drive unit 34 includes a second electric support rod 341 and a second connecting seat 342 arranged sequentially along the vehicle length direction X. The second connecting seat 342 is fixedly connected to the second electric support rod 341 and the first scissor lift unit 31. The drive end of the second electric support rod 341 is drivenly connected to the second scissor lift unit 33.

[0044] like Figure 6 and Figure 7 As shown, the first electric strut 321 outputs power to drive the first scissor lift unit 31 to rise and fall along the vehicle height direction Z, and the second electric strut 341 outputs power to drive the second scissor lift unit 33 to rise and fall along the vehicle height direction Z, thereby adjusting the height of the vehicle roof 2 and enabling the roof 2 to be raised and lowered. The first connecting seat 322 of the first drive unit 32 is fixedly connected to the first electric strut 321 and the second scissor lift unit 33, and the second connecting seat 342 of the second drive unit 34 is fixedly connected to the second electric strut 341 and the first scissor lift unit 31. The first connecting seat 322 and the second connecting seat 342 connect the first lifting assembly 3a and the second lifting assembly 3b into a whole, improving the assembly strength of the entire roof lifting mechanism 3.

[0045] Optionally, the first electric strut 321 has a first fixed section 3211 and a first telescopic section 3212, the first telescopic section 3212 is connected to the first scissor lift unit 31, and the first fixed section 3211 is connected to the first connecting seat 322; the second electric strut 341 has a second fixed section 3411 and a second telescopic section 3412, the second telescopic section 3412 is connected to the second scissor lift unit 33, and the second fixed section 3411 is connected to the second connecting seat 342; the extension directions of the first telescopic section 3212 and the second telescopic section 3412 are opposite.

[0046] like Figure 2As shown, the first electric strut 321 is formed by a first fixed section 3211 and a first telescopic section 3212. The first fixed section 3211 can be fixedly connected to the first connecting seat 322 and the roof 1. The second electric strut 341 is formed by a second fixed section 3411 and a second telescopic section 3412. The second fixed section 3411 can be fixedly connected to the second connecting seat 342 and the roof 1, thereby fixing the first drive unit 32, the second drive unit 34 and the vehicle as a whole.

[0047] The first telescopic section 3212 can drive the first scissor lift unit 31 to rise and fall, and the second telescopic section 3412 can drive the first scissor lift unit 31 to rise and fall. The first telescopic section 3212 and the second telescopic section extend in opposite directions. The space of the first scissor lift unit 31 and the second scissor lift unit 33 in the vehicle length direction X can be used as the telescopic space of the first telescopic section 3212 and the second telescopic section 3412, respectively, thereby improving the space utilization rate in the vehicle length direction X.

[0048] Optionally, the first scissor lift unit 31 includes an upper slide rail 311, a lower slide rail 312, a first scissor lift arm 313, and a second scissor lift arm 314. The top of the upper slide rail 311 is fixedly connected to the top cover 2, and the bottom of the lower slide rail 312 is fixedly connected to the roof 1. The middle part of the first scissor lift arm 313 is hinged to the middle part of the second scissor lift arm 314. The top of the first scissor lift arm 313 is hinged to the upper slide rail 311, and the bottom of the first scissor lift arm 313 is slidably engaged with the lower slide rail 312 along the vehicle length direction X. The bottom of the first scissor lift arm 313 is drively connected to the first drive unit 32. The bottom of the second scissor lift arm 314 is hinged to the lower slide rail 312, and the top of the second scissor lift arm 314 is slidably engaged with the upper slide rail 311 along the vehicle length direction X.

[0049] The first scissor lift unit 31 and the second scissor lift unit 33 have the same structure. Here, we will only use the first scissor lift unit 31 as an example to describe the structure.

[0050] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the top of the upper slide rail 311 is fixedly connected to the cover plate, and the bottom of the lower slide rail 312 is fixedly connected to the vehicle roof 1, thus fixing the first scissor lift unit 31 to the vehicle. When the first drive unit 32 drives the bottom of the first scissor lift arm 313 to slide along the length direction of the vehicle on the lower slide rail 312, since the middle part of the first scissor lift arm 313 is hinged to the middle part of the second scissor lift arm 314, the first scissor lift arm 313 can drive the second scissor lift arm 314 to move synchronously through the hinged position, so that the first scissor lift arm 313 rotates around its top, the second scissor lift arm 314 rotates around its top, and the bottom of the first scissor lift arm 313 slides along the length direction X of the vehicle on the lower slide rail 312, while the top of the second scissor lift arm 314 slides along the length direction X of the vehicle on the upper slide rail 311, and the bottom of the first scissor lift arm 313 slides along the length direction X of the vehicle on the lower slide rail 312, thereby adjusting the distance between the upper slide rail 311 and the lower slide rail 312, and realizing the adjustment of the vehicle roof 2 in the height direction.

[0051] Optionally, the first scissor lift unit 31 further includes a limiting member 315. The upper slide rail 311 and the lower slide rail 312 are both provided with limiting members 315. The limiting member 315 is located between the second scissor lift arm 314 and the first scissor lift arm 313. The top of the second scissor lift arm 314 and the bottom of the first scissor lift arm 313 respectively cooperate with the limiting member 315 along the X stop direction of the vehicle length.

[0052] like Figure 4 and Figure 5 As shown, a limiting member 315 is provided between the first scissor arm 313 and the second scissor arm 314 on the upper slide rail 311 and the lower slide rail 312. The limiting member 315 can limit the sliding stroke of the first scissor arm 313 and the second scissor arm 314, limit the maximum lifting range of the vehicle's roof 2, and prevent the distance between the top of the first scissor arm 313 and the top of the second scissor arm 314 from being too small when the rotation angle of the first scissor arm 313 and the second scissor arm 314 is too large, which would affect the stability of the roof 2.

[0053] Optionally, the upper slide rail 311 and the lower slide rail 312 have the same structure. The upper slide rail 311 includes a base plate 316 and a side plate 317 connected to the base plate 316. There are two side plates 317, which are spaced apart along the vehicle width direction Y. The base plate 316 and the two side plates 317 enclose each other to form a slide rail 318. The top of the second scissor arm 314 is slidably mounted on the slide rail 318, and the limiting member 315 is connected to the base plate 316.

[0054] Both the upper slide rail 311 and the lower slide rail 312 are formed by the base plate 316 and two side plates 317. The slide rail 318 formed by the base plate 316 and the two side plates 317 can accommodate the top of the second scissor arm 314 and the bottom of the first scissor arm 313, and guides the sliding of the first scissor arm 313 and the second scissor arm 314, ensuring the stability of the first scissor arm 313 and the second scissor arm 314 when driving the top cover 2 to rise and fall.

[0055] Optionally, the limiting member 315 includes a limiting screw, and the base plate 316 is provided with a fixing hole 319. The fixing hole 319 is an oblong hole extending along the length direction X of the vehicle, and the limiting screw passes through the fixing hole 319.

[0056] like Figure 4 and Figure 5 As shown, the limiting member 315 is formed by a limiting screw and passes through the fixing hole 319 of the base plate 316. The limiting screw can be fixed to the vehicle's roof 2 or roof 1, and while limiting the stroke of the first scissor arm 313 and the second scissor arm 314, it also has the function of fastening the base plate 316. The fixing hole 319 is an oblong hole extending along the vehicle's length direction X, which allows adjustment of the assembly position of the limiting member 315 in the vehicle's length direction X to adjust the maximum lifting range of the roof 2 within a small range.

[0057] This application also provides a preferred embodiment of a roof structure, including a roof 1, a roof cover 2 and a roof lifting mechanism 3. Two sets of roof lifting mechanisms 3 are spaced apart between the roof 1 and the roof cover 2 along the vehicle width direction Y. The specific structure of the roof lifting mechanism 3 is the same as that of the roof lifting mechanism 3 in any of the above embodiments, and will not be described again here.

[0058] A roof lifting mechanism 3 is installed at both ends of the vehicle width direction Y between the roof 1 and the roof cover 2, which eliminates the lifting components of the roof 1 and the roof cover 2 in the vehicle length direction X, thus saving the space originally used to install the lifting mechanism at both ends of the vehicle length direction X.

[0059] A preferred embodiment of a vehicle according to this application includes a roof structure. The specific structure of the roof structure is the same as that of the roof structure described in the above embodiments, and will not be repeated here.

[0060] In summary, the embodiments of this application provide a roof lifting mechanism, a roof structure, and a vehicle. The first scissor unit of the first lifting assembly and the second scissor unit of the second lifting assembly are spaced apart along the length of the vehicle and respectively connected between the roof and the roof. The first scissor unit and the second scissor unit can simultaneously drive the roof to move up and down along the height of the vehicle to adjust the height of the roof. In addition, the first drive unit and the second drive unit are spaced apart along the height of the vehicle, which can make reasonable use of the space occupied by the first scissor unit and the second scissor unit in the height of the vehicle to simultaneously set up the first drive unit and the second drive unit, reducing the overall space occupied by the first lifting assembly and the second lifting assembly and improving the space utilization rate.

[0061] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
