DETAILED DESCRIPTION

[0031] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0032] In this disclosure, unless otherwise stated, directional words such as "up, down, left, right, front, and back" are used in the same way as the directions of up, down, left, right, front, and back when the unmanned vehicle 100 is in normal driving. The direction of the front 11 of the unmanned vehicle 100 is the front, the direction opposite to the front 11 is the back, the direction of the unmanned vehicle 100 close to the bottom is the bottom, and the direction away from the bottom is the top. The left and right directions can be determined based on the front and back. For specific directions, please refer to Figure 1 and Figure 3 "Inside" and "outside" refer to the inside and outside of the outline of the relevant structure. In addition, the terms "first" and "second" used in the embodiments of the present disclosure are used to distinguish one element from another and do not have order or importance.

[0033] like Figures 1 to 9As shown, the present disclosure provides an unmanned vehicle 100, which includes a body 10 and a cover structure 20. The body 10 includes a chassis 12 and a front 11. The upper surface of the chassis 12 includes a first area 121 and a second area 122 arranged along the front and rear directions of the unmanned vehicle 100. The front 11 is arranged in the first area 121. The cover structure 20 includes a cover 21, and the cover structure 20 is detachably mounted on the body 10 so that the unmanned vehicle 100 can have a first state and a second state.

[0034] In the first state, the second area 121 on the chassis 12, the front 11 and the cover 21 together define a space for accommodating cargo (such as Figure 2 The size of the cargo that the unmanned vehicle 100 can transport depends primarily on the location of the cover 21 attached to the vehicle body 10, as this location determines the size of the aforementioned storage space. In the second state, the cover structure 20 is separated from the vehicle body 10, and the second area 121 is used to carry cargo. In this state, the cover structure 20 is temporarily removed from the vehicle body 10. In this second state, the removal of the cover structure 20 frees the storage space from the restriction imposed by the cover 21, increasing the cargo storage space available to the unmanned vehicle 100.

[0035] like Figure 2 and Figure 3 As shown, in the unmanned vehicle 100 provided herein, since the unmanned vehicle 100 has the aforementioned first and second states, the state of the unmanned vehicle 100 can be selected based on the type and size of the cargo being transported. For example, if the cargo is small and requires a smaller container 200 (e.g., a food container), the cargo can be placed in a dedicated container 200, which can then be placed into the aforementioned storage space. In this case, the unmanned vehicle 100 can remain in the first state. However, if the cargo is larger and requires a larger container 200 (e.g., a parcel locker), the storage space may be insufficient. In this case, the cover structure 20 can be removed from the unmanned vehicle 100. After the cover structure 20 is removed, the loading space can be increased. For example, the container 200 can be allowed to extend rearward beyond the second region 121 of the chassis 12 in the fore-aft direction of the unmanned vehicle 100 (i.e., the length of the unmanned vehicle 100). The container 200 can also be made taller than the vehicle head 11. This allows the unmanned vehicle 100 to be loaded without any constraints, thus increasing its loading space. Moreover, the cover structure 20 can be installed and disassembled in an overall modular manner, which can save installation and disassembly efficiency.

[0036] As can be seen from the above, in the present disclosure, the cargo storage space of the unmanned vehicle 100 can be modified to accommodate different transportation needs. For cargo of different sizes, a single model of unmanned vehicle 100 can be used, eliminating the need to design two different models of vehicles, as they can share the same chassis 12, thus reducing costs.

[0037] In addition, in the present disclosure, when the unmanned vehicle 100 is in the first state, that is, when the cover structure 20 is installed on the vehicle body 10, as shown in FIG. Figure 2 As shown, onboard sensors (such as cameras, radars, etc.) used to obtain environmental information around the unmanned vehicle 100 to assist in the autonomous driving of the unmanned vehicle 100 can be installed on the vehicle body 10, or on the cover structure 20. Alternatively, if there are multiple onboard sensors, some of the onboard sensors can be arranged on the front 11 and others on the cover structure 20. This increases the options for the layout of the onboard sensors and allows them to be unaffected by space.

[0038] In addition, when the unmanned vehicle 100 is in a Figure 3 In the second state shown, the container 200 can be designed so that the volume and shape of the container 200 meet the requirements. Figure 3 FIG. 2 shows only a three-dimensional container. In other embodiments, the container 200 may have other shapes.

[0039] It is understandable that the unmanned vehicle 100 can fix the container 200 on the second area 121 of the chassis 12 in both the first state and the second state to prevent the container 200 from shifting or accidentally falling out of the storage space during transportation.

[0040] In the present disclosure, the cover structure 20 and the vehicle body 10 can be detachably connected using any appropriate structure, and the present disclosure does not limit this. Figures 4 to 9 As shown, in one embodiment of the present disclosure, a first cross beam 111 is provided on the front of the vehicle 11, and the unmanned vehicle 100 also includes a first threaded fastener 30. A second cross beam 211 is provided on the front side of the cover body 21, and a first threaded hole 1111 and a second threaded hole 2111 are respectively provided on the first cross beam 1111 and the second cross beam 211. The first threaded fastener 30 is used to be inserted into the first threaded hole 1111 and the second threaded hole 2111 to connect the first cross beam 111 and the second cross beam 211 into one, thereby connecting the front side of the cover body 21 to the vehicle body.

[0041] like Figure 7 and Figure 8As shown, a third cross beam 123 may be provided on the chassis 12, and the unmanned vehicle 100 further includes a second threaded fastener 40. A fourth cross beam 212 is provided on the rear side of the cover body 21, and a third threaded hole 1231 and a fourth threaded hole 2121 are provided on the third cross beam 123 and the fourth cross beam 212, respectively. The second threaded fastener 40 is used to be inserted into the third threaded hole 1231 and the fourth threaded hole 2121 to connect the third cross beam 123 and the fourth cross beam 212 into one, thereby connecting the rear side of the cover body 21 to the vehicle body.

[0042] In this embodiment, a first crossbeam 111, a second crossbeam 211, a third crossbeam 123 and a fourth crossbeam 212 are provided, and a first threaded fastener 30 and a second threaded fastener 40 are used in conjunction so that when the unmanned vehicle 100 is in the first state, the cover structure 20 can be screwed to the vehicle body 10. The screw connection has the advantage of reliable installation while achieving detachable installation.

[0043] Specifically, when the unmanned vehicle 100 is in the first state, the first crossbeam 111 and the second crossbeam 211 are connected as one with the first threaded fastener 30, and the third crossbeam 123 and the fourth crossbeam 212 are connected as one with the second threaded fastener 40. When the unmanned vehicle 100 needs to be switched to the second state, the first crossbeam 111 and the second crossbeam 211 locked by the first threaded fastener 30 and the third crossbeam 123 and the fourth crossbeam 212 locked by the second threaded fastener 40 are released. The installation and disassembly operations of the cover structure 20 and the vehicle body are convenient.

[0044] In order to improve the reliability of the connection between the cover structure 20 and the vehicle body 10, Figure 6 、 Figure 8 and Figure 9 As shown, the first threaded hole 1111, the second threaded hole 2111, the third threaded hole 1231 and the fourth threaded hole 2121 can be multiple, and the multiple first threaded holes 1111, the multiple second threaded holes 2111, the multiple third threaded holes 1231 and the multiple fourth threaded holes 2121 can be arranged at intervals along the left and right directions of the unmanned vehicle 100 on the corresponding first beam 111, the second beam 211, the third beam 123 and the fourth beam 212.

[0045] The first threaded fastener 30 and the second threaded fastener 40 may be M8 bolts, which is not limited in the present disclosure.

[0046] It will be appreciated that, in the above-described embodiment, the connection structure between the front side of the cover structure 20 and the front end 11, and the connection structure between the rear side of the cover structure 20 and the chassis 12 are identical (all being screwed connections). In other embodiments of the present disclosure, the two may employ different connection structures, and other connection structures besides the screwed connections described above may also be employed. For example, in one embodiment of the present disclosure, the front side of the cover structure 20 may be provided with a buckle, the front end 11 may be provided with a tongue that engages with the buckle, and the rear side of the cover structure 20 may be riveted to the chassis 12.

[0047] Alternatively, as Figure 7 As shown, the first threaded fastener 30 can be installed along the front-to-back direction of the unmanned vehicle 100. Specifically, the axis of the first threaded hole and the second threaded hole is aligned with the front-to-back direction of the unmanned vehicle 100, and the front end of the first threaded fastener 30 passes through the second threaded hole and is screwed into the first threaded hole.

[0048] Alternatively, as Figure 7 and Figure 8 As shown, the second threaded fastener 40 can be installed in the up-down direction of the unmanned vehicle 100. Specifically, the axis of the third threaded hole and the fourth threaded hole is in the same up-down direction as the unmanned vehicle 100, and the lower end of the second threaded fastener 40 passes through the fourth threaded hole and is screwed and fixed in the third threaded hole.

[0049] Optionally, the first cross beam 111 can be installed on the rear end surface of the front end 11 by welding, screwing, etc., and the third cross beam 122 can be installed on the second area 121 of the chassis 12 by welding, screwing, etc., which is not limited in this disclosure.

[0050] In order to facilitate the installation of the cover structure 20, the unmanned vehicle 100 may further include a positioning structure 50, optionally, as Figures 5 to 9 As shown, the positioning structure 50 includes a first positioning member 51 and a second positioning member 52. The first positioning member 51 is disposed on one of the cover structure 20 and the vehicle body 10, and the second positioning member 52 is disposed on the other of the cover structure 20 and the vehicle body 10. The first positioning member 51 is provided with a positioning pin 511, and the second positioning member 52 is provided with a positioning hole 521 that cooperates with the positioning pin 511. When installing the cover structure 20, the positioning pin 511 on the first positioning member 51 can be inserted into the positioning hole 521 on the second positioning member 52 to achieve pre-positioning of the installation, thereby facilitating the installation of the cover structure 20 and the vehicle body 10.

[0051] The present disclosure does not limit the specific number and installation position of the first positioning member 51 and the second positioning member 52, as long as the cover structure 20 and the vehicle body 10 can be pre-positioned. Figure 4As shown, in one embodiment of the present disclosure, there are two first positioning members 51, which are spaced apart on the front 11 of the unmanned vehicle 100 along the left-right direction (i.e., the width direction). Correspondingly, there are two second positioning members 52, which are spaced apart on the cover structure 20 along the left-right direction of the unmanned vehicle 100. The cooperation of the two first positioning members 51 and the two second positioning members 52 allows the front side of the cover structure 20 to be positioned relative to the vehicle body, thereby ensuring the positioning of the entire cover structure 20.

[0052] The second positioning member 52 can be installed at any appropriate position on the cover structure 20, for example, it can be installed on the second cross beam 211 mentioned above, or it can be installed on the second side beam 213 mentioned below, which is not limited in this disclosure.

[0053] like Figures 5 to 9 As shown, the front 11 has a pair of first side beams 112 arranged opposite each other in the left-right direction of the unmanned vehicle 100. The cover 21 has a pair of second side beams 213 arranged opposite each other in the left-right direction of the unmanned vehicle 100. The first locating member 51 is mounted on the rear end of the first side beam 112, and the second locating member 52 is mounted on the front end of the second side beam 213. The provision of the second side beams 213 to mount the second locating member 52 helps prevent the second locating member 52 from interfering with the cargo space of the unmanned vehicle 100 after the cover structure 20 is mounted on the vehicle body 10. Furthermore, the provision of the second side beams 213 helps to improve the structural strength of the cover.

[0054] The present disclosure does not limit the specific structure of the first positioning member 51 and the second positioning member 52 and the installation method of the corresponding side beam. Figure 6 and Figure 9As shown, in one embodiment of the present disclosure, the first positioning member 51 includes a first main body plate 512 and a first protrusion 513, the first protrusion 513 and the positioning pin 511 are relatively arranged on both sides of the first main body plate 512, the first protrusion 513 is inserted into the first side beam 112 and welded to the inner wall of the first side beam 112, and / or, the second positioning member 52 includes a second main body plate 522 and a second protrusion 523, the second protrusion 523 is inserted into the second side beam 213 and welded to the inner wall of the second side beam 213, and the positioning hole 521 passes through at least the second main body plate 522. By inserting the first protrusion 513 into the first side beam 112 and the second protrusion 523 into the second side beam 213 and welding them together, while improving the connection reliability between the first positioning member 51 and the first side beam 112, and the second positioning member 52 and the second side beam 213, the internal hollow structure of the first side beam 112 and the second side beam 213 is used to hide part of the structure of the positioning member, reducing the exposed size of the first positioning member 51 and the second positioning member 52, and further reducing the interference of the first positioning member 51 and the second positioning member 52 with the cargo storage space of the unmanned vehicle 100.

[0055] risk.

[0056] In other embodiments of the present disclosure, a first positioning member 51 can be installed on the front side of the cover structure 20 to cooperate with a second positioning member 52 installed on the front of the vehicle 11, and another first positioning member 51 can be installed on the rear side of the cover structure 20 to cooperate with another second positioning member 52 installed on the chassis 12. In this way, the pre-positioning of the cover structure 20 during installation can also be achieved by arranging the positioning members in the front and rear.

[0057] In the present disclosure, the second protrusion 523 of the second positioning member 52 can be adapted to the shape of the hollow portion of the second side beam 213. For example, when the cross section of the second side beam 213 is a regular shape such as a rectangle or a circle, the cross section of the second protrusion 523 can also be a regular shape such as a rectangle or a circle of corresponding size. Figure 9 When the special-shaped structure is shown, the second protrusion 523 can also be set to a special-shaped structure that matches it.

[0058] like Figure 6 and Figure 9 As shown, in an optional embodiment, the second protrusion 523 includes two connected first extension portions 5231, and the size of each extension portion of the two first extension portions 5231 gradually increases from one end where the two are connected to the other end, and the positioning hole 521 is located at the position where the two first extension portions 5231 are connected.

[0059] The second main plate 522 of the second positioning member 52 can be adapted to the cross-sectional shape of the second side beam 213 to enhance the aesthetic appearance of the unmanned vehicle 100 when the unmanned vehicle 100 is in the second state. Optionally, the second main plate 522 can include two second extensions 5221 having the same shape as the first extension 5231, and the second extensions 5221 can be larger than the first extensions 5231.

[0060] Likewise, in the present disclosure, the first protrusion 513 of the first positioning member 51 may be adapted to the shape of the hollow portion of the first side beam 112. Figure 6 and Figure 9 As shown, in an optional embodiment, the first protrusion 513 includes two connected third extensions 5131, and the size of each extension 5131 gradually increases from one end where the two are connected to the other end, and the positioning pin 511 is located at the position where the two third extensions 5131 are connected.

[0061] The first main plate 512 of the first positioning member 51 can be adapted to the cross-sectional shape of the first side beam 112 to enhance the aesthetic appearance of the unmanned vehicle 100 when the unmanned vehicle 100 is in the second state. Optionally, the first main plate 512 can include two fourth extensions 5121 having the same shape as the third extension 5131, and the fourth extensions 5121 can be larger than the third extensions 5131.

[0062] The present disclosure does not limit the specific structure of the cover structure 20 and the cover body 21. Figure 4 As shown, in one embodiment of the present disclosure, the cover 21 includes a first portion 201 and a second portion 202 connected in an L-shape. The first portion 201 extends horizontally, with the front end of the first portion 201 detachably connected to the vehicle head 11. The second portion 202 extends vertically, with the upper end of the second portion 202 connected to the rear end of the first portion 201, and the lower end of the second portion 202 detachably connected to the chassis 12. Based on this, when the cover 21 is connected to the vehicle body 10, the first portion 201 of the cover 21 corresponds to the roof of the unmanned vehicle 100, and the second portion 202 of the cover 21 corresponds to the rear side wall of the unmanned vehicle 100. The L-shaped structure of the cover 21 is conducive to increasing the storage space of the unmanned vehicle 100 while maintaining a simple structure.

[0063] like Figure 4 and Figure 7As shown, the cover 21 may include a frame and a plate 214 fixed to the frame. As mentioned above, the frame may include a pair of second side beams 213 arranged relative to each other in the left and right directions of the unmanned vehicle 100, and a first crossbeam 111 and a second crossbeam 211 connected between the pair of second side beams 213.

The second crossbeam 211 is located on the rear side of the frame and at the lower end of the frame and is used to be detachably connected to the chassis 12. The second side beams 213 and the plate 214 may both be L-shaped, that is, the second side beams 213 may also include horizontal beams and vertical beams, and the plate 214 may include horizontal plates and vertical plates. The cover 21 includes a structure of a frame and a plate. While ensuring that the strength of the cover 21 structure meets the requirements, it is also convenient to connect to the front end 11 and the chassis 12. For example, it is convenient to install the above-mentioned second positioning member 52 and to open the second threaded hole 2111 and the fourth threaded hole 2121.

[0064] In order to facilitate the installation of the plate body 214 and the second side beam 213 , a pair of second side beams 213 are further provided with stepped surfaces on their surfaces facing each other, and the plate body 214 can be overlapped and welded on the stepped surfaces.

[0065] In order to further ensure that the structural strength of the cover plate meets the requirements, optionally, in addition to the second crossbeam 211 and the fourth crossbeam 212 , the frame structure of the cover plate may further include other crossbeams located between the second crossbeam 211 and the fourth crossbeam 212 .

[0066] In addition, in the present disclosure, the unmanned vehicle 100 also includes an on-board sensor for obtaining information about the environment around the unmanned vehicle 100. The on-board sensor is arranged on the vehicle body 10, and / or the on-board sensor is arranged on the cover structure 20. Obtaining environmental information around the unmanned vehicle 100 through the on-board sensor can assist the unmanned vehicle 100 in automatic driving. As mentioned above, when the unmanned vehicle 100 is in the first state, the on-board sensor can be installed on the vehicle body 10, or the on-board sensor can be installed on the cover structure 20. Or, when there are multiple on-board sensors, some of the on-board sensors can be arranged on the front of the vehicle 11, and another part of the on-board sensors can be arranged on the cover structure 20. In this way, the options for the layout of the on-board sensors are increased, which is conducive to ensuring that the on-board sensors are not affected by space. When the unmanned vehicle 100 is in the second state, the on-board sensor can be arranged on the front of the vehicle 11.

[0067] Here, the vehicle-mounted sensing component may include at least one of components such as radar, sensor, camera, antenna and GPS navigator, but is not limited thereto.

[0068] Optionally, in one embodiment of the present disclosure, Figure 2As shown, the vehicle-mounted sensing components include a first camera 61, a second camera 62, a third camera 63, a fourth camera 64 and a laser radar 70. The first camera 61 is arranged on the top of the front of the vehicle 11 to obtain environmental information in front of the unmanned vehicle 100, and the second camera 62 is arranged near the rear end of the cover structure 20 to obtain environmental information behind the unmanned vehicle 100. The third camera 63 and the fourth camera 64 are arranged on both sides of the cover structure 20 in the left and right directions of the unmanned vehicle 100 to obtain environmental information on the side of the unmanned vehicle 100. The laser radar 70 is installed on the outer surface of the cover 21 or on the top surface of the front of the vehicle 11. When the unmanned vehicle 100 is in the first state, as shown in FIG. Figure 2 As shown, the laser radar 70 can be installed on the outer surface of the cover 21. When the unmanned vehicle 100 is in the second state, as shown in FIG. Figure 3 As shown, the laser radar 70 can be installed on the top surface of the front of the vehicle 11. The laser radar 70 can be used together with the above-mentioned camera to obtain environmental information around the unmanned vehicle 100.

[0069] like Figure 2 and Figure 3 As shown, the unmanned vehicle 100 also includes a mounting frame 80, which includes a mounting plate 81 and supporting legs relatively arranged at both ends of the mounting plate 81, and the lower end of each supporting leg is connected to the cover 21 or the front of the vehicle 11. The laser radar 70 is installed on the mounting plate 81. In this way, the laser radar 70 can be kept a certain distance away from the cover 21 or the front of the vehicle 11 to avoid the top surface of the cover 21 or the front of the vehicle 11 affecting the detection of the laser radar 70, thereby increasing the detection range of the laser radar 70.
