The words "connected" or "connected" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0033] The present application discloses a vehicle, comprising a vehicle body, wherein the vehicle body is not only a part of the vehicle for loading goods or passengers, but also a basis for installing and connecting other parts of the vehicle.

[0034] See also Figure 1 In one embodiment, the vehicle body includes a vehicle body 10 and a door 11, and the door 11 is rotatably mounted on the vehicle body 10. When the door 11 is opened, the user can enter the vehicle through the door 11, and after the user enters the vehicle, the door 11 can be closed.

[0035] See also Figures 1 to 3In one embodiment, the vehicle body further includes a door opening device 12, and the vehicle door 11 includes an outer panel 111 and an inner panel 112 arranged opposite to each other; the door opening device 12 is installed on the side of the inner panel 112 facing away from the outer panel 111. In other words, the vehicle door 11 divides the vehicle into an interior space of the vehicle and an exterior space of the vehicle, and the inner panel 112 of the vehicle door 11 and the outer panel 111 of the vehicle door 11 enclose an installation space, namely, the interior space of the vehicle door 11. The door opening device 12 is arranged outside the interior space of the vehicle door 11 and is located in the interior space of the vehicle. As a result, the door opening device 12 does not need to occupy the interior space of the vehicle door 11, and can avoid interfering with the movement of other accessories such as door glass arranged in the interior space of the vehicle door 11, and avoid becoming a limiting factor in the shape of the door glass. In addition, by arranging the door opening device 12 on the side of the vehicle door 11 facing the interior space of the vehicle, it is also avoided that the appearance effect of the overall shape of the vehicle is affected when the door opening device 12 is arranged on the side of the vehicle door 11 facing the exterior space of the vehicle.

[0036] See also Figure 1 and Figure 3 In one embodiment, the vehicle door 11 is rotatably mounted on the vehicle body 10 via a rotating component 13; the inner panel 112 includes an inner panel body 1121 and an edge portion 1122 disposed around the inner panel body 1121; the vehicle door opening device 12 is mounted on a side of the edge portion 1122 close to the rotating component 13 and connected to the rotating component 13. Thus, the vehicle door opening device 12 can be prevented from occupying the space of the inner panel body 1121, and the connection path between the vehicle door opening device 12 and the rotating component 13 is shortened.

[0037] Usually, the rotating component 13 is installed on the side of the door 11 close to the front of the vehicle and connected to the vehicle body 10. The inner panel body 1121 may be provided with an edge portion 1122 in the circumference, and the door opening device 12 is installed at a position where the edge portion 1122 is closer to the front of the vehicle. In addition, the number of rotating components 13 is generally two, which are arranged at intervals along the vertical direction on the side of the door 11 close to the front of the vehicle. The door opening device 12 is installed at a position where the edge portion 1122 is closer to the rotating component 13 arranged at the lower part of the door.

[0038] The edge portion 1122 may be integrally formed with the inner plate body 1121, or may be processed separately and then connected together.

[0039] Please continue reading Figure 3In one embodiment, the inner panel body 1121 is protruded in a direction away from the outer panel 111, and includes a first surface 11211 and a second surface 11212; the first surface 11211 is arranged opposite to the outer panel 111; the second surface 11212 is located between the first surface 11211 and the outer panel 111, and is connected to the first surface 11211 and the outer panel 111; the edge portion 1122 is bent and extended outward from the second surface 11212; the door opening device 12 is installed in the space enclosed by the edge portion 1122 and the second surface 11212. Therefore, the protruding inner panel body 1121 can shield the door opening device 12 to a certain extent, thereby improving the appearance of the overall shape of the door 11.

[0040] Among them, the edge portion 1122 is in contact with the outer panel 111 and fixedly connected, such as by welding; the first surface 11211, the second surface 11212 and the outer panel 111 enclose an internal space of the vehicle door for assembling other accessories such as door glass and other components.

[0041] It should be noted that the first surface 11211 may be parallel or substantially parallel to the outer plate 111. Figure 2 As shown in the outer plate 111 , the extension direction of the plane where the outer plate 111 is located is perpendicular to the paper surface. Correspondingly, the extension direction of the plane where the first surface 11211 is located is also perpendicular to the paper surface.

[0042] See also Figure 2 and Figure 3 In one embodiment, the vehicle door 11 further comprises an interior panel 113 disposed away from the outer panel 111 relative to the edge portion 1122, and the vehicle door opening device 12 is disposed between the interior panel 113 and the edge portion 1122. Thus, it is convenient to hide the vehicle door opening device 12 to improve the aesthetics of the vehicle door.

[0043] The interior trim panel 113 may be an interior trim flange extending outward from the second surface 11212. The interior trim flange, a part of the structure of the second surface and the edge portion 1122 together enclose an accommodation space for accommodating the vehicle door opening device 12.

[0044] See also Figure 4 and Figure 5In one embodiment, the door opening device 12 includes a driving mechanism 121 and a hydraulic transmission mechanism 122; the door 11 is rotatably mounted on the vehicle body 10 through a rotating component 13; the driving mechanism 121 is connected to the hydraulic transmission mechanism 122, and the hydraulic transmission mechanism 122 is also connected to the rotating component 13; the driving mechanism 121 can drive the rotating component 13 to rotate through the hydraulic transmission mechanism 122, so as to drive the door 11 to rotate relative to the vehicle body 10. Therefore, compared with the traditional process of using a mechanical transmission mechanism to transmit power, the hydraulic transmission mechanism 122 provided in the present application adopts a non-rigidly connected transmission mechanism to achieve energy transmission by means of a liquid transmission medium; compared with the traditional mechanical transmission mechanism, it can not only avoid the wear of the power input element and the power output element in the transmission mechanism, prolong the service life, but also better absorb the impact and vibration from the external load.

[0045] See also Figure 6 and Figure 7 In one embodiment, the hydraulic transmission mechanism 122 includes a housing 1221 and a liquid transmission medium, a power input element and a power output element arranged in the housing 1221; the housing 1221 includes at least a first portion 12211 and a second portion 12212 arranged at an angle; the power input element is arranged in the first portion 12211 and connected to the driving mechanism 121; the power output element is arranged in the second portion 12212 and connected to the rotating component 13. Thus, the volume of the hydraulic transmission mechanism 122 can be reduced as much as possible to reduce the occupied area of ​​the hydraulic transmission mechanism 122. In one embodiment, the connection between the first portion 12211 and the second portion 12211 is a smooth transition, thereby reducing the flow resistance of the liquid transmission medium.

[0046] See also Figure 3 and Figure 4 In one embodiment, the axis of the driving mechanism 121 is arranged parallel to the door 11; in other words, when the door 11 is closed, the plane where the door 11 is located is perpendicular or substantially perpendicular to the horizontal plane, and the axis of the driving mechanism 121 is arranged parallel to the plane where the door 11 is located. The first portion 12211 extends in a direction parallel to the axis of the driving mechanism 121. Thus, the driving mechanism 121 and the hydraulic transmission mechanism 122 can be assembled more compactly, saving the installation space of the door opening device 12.

[0047] Please continue reading Figure 3In one embodiment, the first portion 12211 extends longer than the second portion 12212. Thus, the installation space occupied along the thickness direction of the vehicle door 11 can be reduced. It should be noted that the thickness of the vehicle door 11 is the length of the vehicle door extending from the interior space of the vehicle to the exterior space of the vehicle. In one embodiment, the second portion 12212 is perpendicular to the first portion 12211 and is arranged in different planes to further reduce the overall size of the hydraulic transmission mechanism 122.

[0048] See also Figures 5 to 7 In one embodiment, the door opening device 12 further includes a speed reduction mechanism 123, through which the drive mechanism 121 is connected to the power input element; the axis of the speed reduction mechanism 123 is collinear with the axis of the power input element, and the axis of the speed reduction mechanism 123 is perpendicular to the axis of the drive mechanism 121. Thus, the speed reduction mechanism 123 can reduce the speed output by the drive mechanism 121 to ensure the smooth operation of the hydraulic transmission mechanism 122. By setting the axis of the speed reduction mechanism 123 to be collinear with the axis of the power input element and perpendicular to the axis of the drive mechanism 121, it is possible to ensure that the assembly between the drive mechanism 121, the speed reduction mechanism 123 and the hydraulic transmission mechanism 122 is more compact, thereby reducing the installation space of the door opening device 12.

[0049] In one embodiment, the first portion 12211 of the housing 1221 continues to bend and extend to one side along the same plane from one end away from the second portion 12212, so as to be connected to the speed reduction mechanism 123. Of course, the specific structure of the housing 1221 is not limited thereto, and can be adaptively adjusted according to the actual space size of the door, for example, it can be "L" shaped or "Z" shaped, but is not limited thereto.

[0050] See also Figure 4 and Figure 5 In one embodiment, the vehicle body further comprises a fender 14 mounted on the vehicle body 10, and the fender 14 is arranged adjacent to the vehicle door 11; the driving mechanism 121 is installed on the inner side of the fender 14. Thus, by installing a part of the structure of the door opening device 12, namely the driving mechanism 121, on the inner side of the fender 14, the installation space occupied by the vehicle door 11 can be further reduced, and the requirement for the arrangement space of the driving mechanism 121 is reduced. The inner side of the fender 14 refers to the side of the fender 14 facing the interior of the vehicle. Of course, the specific location of the driving mechanism 121 is not limited to this.

[0051] See also Figure 6 and Figure 7In one embodiment, the hydraulic transmission mechanism 122 also includes a circulation pipeline 1222 arranged in the shell 1221; the circulation pipeline 1222 is filled with a liquid transmission medium; the power input element and the power output element are rotatably arranged at opposite ends of the circulation pipeline 1222 respectively; when the power input element is in a rotating state, it can push the liquid transmission medium to flow in the circulation pipeline 1222 to drive the power output element to rotate.

[0052] The power input element can be matched with the power output element through the liquid transmission medium. When the driving mechanism 121 drives the power input element of the hydraulic transmission mechanism 122 to rotate through the speed reduction mechanism 123, the speed and pressure of the liquid transmission medium around the power input element can be increased to achieve the conversion of mechanical energy into the kinetic energy of the liquid transmission medium. The liquid transmission medium with kinetic energy can impact the power output element during the flow in the circulation pipeline 1222, and transfer part of the energy released by the liquid transmission medium to the power output element, causing the power output element to rotate, and then the power output element transmits power to the door 11 to drive the door 11 to rotate.

[0053] In the above scheme, the power input element and the power output element are connected only by the liquid transmission medium, and the power input element and the power output element are not in direct contact. Therefore, even if the power output element is stuck, the power input element and the drive mechanism 121 can still continue to operate without damaging the hydraulic transmission mechanism 122, thereby improving the service life of the drive mechanism.

[0054] In one embodiment, the shell 1221 and the circulation pipeline 1222 can be formed by metal materials or plastics that meet certain strength requirements.

[0055] See also Figure 7 and Figure 8In one embodiment, the power input element includes a first gear 1225, and the power output element includes a second gear 1226; part of the gear teeth of the first gear 1225 contacts the inner tube wall at the first end 12221 of the circulation pipeline 1222, and part of the gear teeth of the second gear 1226 contacts the inner tube wall at the second end 12222 of the circulation pipeline 1222; so as to separate the circulation pipeline 1222 into a first flow path 1223 and a second flow path 1224, and the flow direction of the liquid transmission medium in the first flow path 1223 is opposite to the flow direction of the liquid transmission medium in the second flow path 1224. Thus, when the hydraulic transmission mechanism 122 is stationary, the first gear 1225 and the second gear 1226 can separate the first flow path 1223 and the second flow path 1224, and prevent the liquid transmission medium from passing through the gap between the first gear 1225 and the inner tube wall or the gap between the second gear 1226 and the inner tube wall, so as to ensure the sealing and reliability of the hydraulic transmission mechanism 122. When the hydraulic transmission mechanism 122 is in a working state, with the rotation of the first gear 1225, the parts of the multiple gear teeth of the first gear 1225 that are in contact with the hydraulic transmission medium inside the circulation pipeline 1222 can drive the flow of the liquid transmission medium. The liquid transmission medium can circulate in the circulation pipeline 1222 by virtue of the tooth grooves between two adjacent gear teeth, thereby driving the second gear 1226 to rotate.

[0056] The first end 12221 and the second end 12222 are two ends extending along the length direction of the circulation pipeline. In addition, the specific structures of the power input element and the power output element are not limited thereto.

[0057] Please continue reading Figure 7 In one embodiment, the first flow path 1223 and the second flow path 1224 are arranged in parallel and spaced apart. Thus, the structure of the hydraulic transmission mechanism 122 can be made more compact, and the installation space occupied can be reduced.

[0058] It should be noted that the liquid transmission medium may be hydraulic transmission oil, which can play a lubricating role by filling the circulation pipeline 1222 with hydraulic transmission oil. In order to reduce friction loss, the viscosity of the hydraulic transmission oil can be appropriately adjusted according to actual needs.

[0059] In one embodiment, the driving mechanism 121 includes a driving motor, the power input end of the reduction mechanism 123 is connected to the output end of the driving motor, and the power output end of the reduction mechanism 123 is connected to the power input element. When the output end of the driving motor, i.e., the output shaft, rotates forward, the power input element of the hydraulic transmission mechanism 122 is driven to rotate forward through the reduction mechanism 123, and the power input element drives the liquid transmission medium in the circulation pipeline 1222 to flow during the rotation, and then the power output element of the hydraulic transmission mechanism 122 is driven to rotate forward through the flowing liquid transmission medium to control the opening of the vehicle door 11. When the output end of the driving motor, i.e., the output shaft, rotates reversely, the power input element of the hydraulic transmission mechanism 122 can still be driven to rotate reversely through the reduction mechanism 123, and the power input element drives the liquid transmission medium in the circulation pipeline 1222 to flow during the rotation, and then the power output element of the hydraulic transmission mechanism 122 is driven to rotate reversely through the flowing liquid transmission medium to control the closing of the vehicle door 11.

[0060] It should be noted that "forward" and "reverse" refer to two directions of rotation that are opposite to each other, and do not limit the specific direction of rotation. For example, when "forward" means counterclockwise, "reverse" means clockwise; when "forward" means clockwise, "reverse" means counterclockwise.

[0061] See also Figures 7 to 9 In one embodiment, the speed reduction mechanism 123 includes a turbine 1232 and a worm 1231; the worm 1231 is fixedly connected to the output end of the driving motor; the turbine 1232 is drivingly connected to the worm 1231; and is coaxially arranged and fixedly connected to the first gear 1225. Thus, through the cooperation of the turbine 1232 and the worm 1231, a larger transmission ratio can be obtained to achieve the purpose of speed reduction. Specifically, the turbine 1232 can be fixedly connected to the first gear 1225 through the first connecting shaft 12251. Among them, the first connecting shaft 12251 can be integrally formed with the turbine 1232, and can also be integrally formed with the first gear 1225.

[0062] Please continue reading Figure 8 In one embodiment, the reduction mechanism 123 includes a housing 1233 disposed on the periphery of the turbine 1232, and the housing 1233 is provided with at least one mounting point 1234, such as two or three mounting points 1234, but not limited thereto, to complete the assembly with the vehicle body.

[0063] It should be noted that the required transmission ratio can be obtained by presetting the lead of the turbine 1232 and the worm 1231. Of course, the specific structure of the speed reduction mechanism 123 is not limited thereto.

[0064] See also Figure 6In one embodiment, the rotating component 13 includes a body connector 131 and a door connector 132 that are hinged to each other; the body connector 131 is used to be fixedly connected to the body 10; the door connector 132 is fixedly connected to the inner plate 112, and the door connector 132 is connected to the power output element. Therefore, the power output end of the hydraulic transmission mechanism 122 can transmit power to the door 11 through the door connector 132, thereby driving the door 11 to rotate around the body connector 131. Among them, the door connector 132 can be fixedly connected to the second surface 11212.

[0065] See also Figure 6 , Fig.10 and Fig.11 In one embodiment, the door connecting member 132 includes an internal gear 1321, a hinge shaft 1322, and a mounting frame 1323 connected to the hinge shaft 1322; the internal gear 1321 is fixedly connected to the power output element; the hinge shaft 1322 is key-connected to the internal gear 1321, and the mounting frame 1323 is fixedly connected to the inner plate 112. In this way, the connection stability between the door 11 mounting member and the power output element of the hydraulic transmission mechanism 122 can be improved. Please refer to Figure 8 , the second gear 1226 is fixedly connected to the inner gear 1321 through the second connecting shaft 13212. The second connecting shaft 13212 can be integrally formed with the second gear 1226, or integrally formed with the inner gear 1321. An inner key 13211 is formed at the end of the inner gear 1321 away from the second gear 1226, and an outer key is formed on the outer peripheral wall of the hinge shaft 1322. The inner gear 1321 and the hinge shaft 1322 are detachably connected through the cooperation of the inner key 13211 and the outer key, thereby facilitating maintenance and replacement.

[0066] It should be noted that the hinge shaft 1322 can be formed integrally with the mounting bracket 1323, or can be processed separately and then fixedly connected, such as by welding. In addition, the inner key 13211 and the outer key can be splines or flat keys. In one embodiment, the mounting bracket 1323 is provided with a connection hole for connecting with the vehicle door 11, and is fixedly connected to the vehicle door 11 through a fastener such as a rivet passing through the connection hole.

[0067] Please continue reading Fig.11In one embodiment, the body connection member 131 includes a body connection end 1311 and a hinge shaft connection end 1312; the body connection end 1311 is fixedly connected to the body body 10, and the hinge shaft connection end 1312 is rotatably connected to the hinge shaft 1322. As a result, not only is the structure simple, but also the manufacturing cost is low. In one embodiment, the body connection end 1311 includes a body mounting hole 13111, and a fastener such as a screw passes through the body mounting hole 13111 to mount the body connection end 1311 of the body connection member 131 on the body. The number of the body mounting holes 13111 is at least one, for example, it can be two, three or even more.
