[0037] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0038] First embodiment

[0039] See also Figure 1 In this embodiment, an unmanned vehicle frame 1 is provided, which is used to be installed on the chassis 2 of the unmanned vehicle, and the unmanned vehicle frame 1 can be used to install other parts of the unmanned vehicle, so as to provide installation space for other parts or provide bearing function for other parts. Among them, other parts include an operating device (not shown), and the operating device can be a sprayer, which is used to spray pesticides or water. Generally, the sprayer includes an air compressor, a gas tank, a spraying mechanism, etc., which can achieve scientific weeding, prevention of pests and diseases, and spraying of pesticides. Of course, the operating device can also be a sprayer, a duster, a seeding machine, etc. The unmanned vehicle frame 1 has a simple structure and can improve its own strength and ensure its stability. In addition, the stability of other parts when installed on the unmanned vehicle frame 1 can be ensured.

[0040] It should be noted that, in this embodiment, the chassis 2 has a top surface 3 and a bottom surface 4, and the top surface 3 and the bottom surface 4 are oppositely arranged side surfaces. That is, when the unmanned vehicle is placed on the ground and is driving normally, at this time, the bottom surface 4 of the chassis 2 refers to the side close to the ground; correspondingly, the top surface 3 of the chassis 2 refers to the side of the chassis 2 away from the ground.

[0041] Please refer to Figure 1 , Figure 2 and Figure 3 The unmanned vehicle frame 1 includes a fuselage frame 10 and a support frame 20, both of which are used to be installed on the chassis 2 of the unmanned vehicle. Among them, the fuselage frame 10 is used to install some parts on the chassis 2, can provide bearing function to some parts on the chassis 2, and can improve the overall strength of the vehicle body by installing the fuselage frame 10 on the chassis 2. The support frame 20 is used for other parts including operating devices, so as to provide stable bearing capacity to other parts and ensure the stability of parts such as operating devices when the unmanned vehicle is operating. It should be understood that in other embodiments, the setting of the support frame 20 can be cancelled, for example, the operating device on the support frame 20 is removed, and at this time, there are no other parts supported on the support frame 20, and the support frame 20 can be removed at this time.

[0042] See also Figure 2 The fuselage frame 10 includes a first frame 100, a second frame 200 and a third frame 300. The second frame 200 and the third frame 300 are respectively arranged on opposite sides of the first frame 100, and the second frame 200 and the third frame 300 are both connected to the first frame 100.

[0043] Further, one side of the first frame 100 is used to be connected to the top surface 3 of the chassis 2. One side of the second frame 200 is used to be connected to the top surface 3 of the chassis 2, and the other side of the second frame 200 is connected to the other side of the first frame 100, and at the same time, an angle is formed between the first frame 100 and the second frame 200. Due to the angle formed between the first frame 100 and the second frame 200, when the first frame 100 and the second frame 200 are installed on the top surface 3 of the chassis 2, a triangular stable structure can be formed between the first frame 100, the second frame 200 and the chassis 2, thereby ensuring the stability of the first frame 100 and the second frame 200 installed on the chassis 2, and at the same time, the overall strength of the first frame 100 and the second frame 200 can be improved.

[0044] It should be noted that, in the present embodiment, the side of the first frame 100 close to the second frame 200 and the side of the second frame 200 close to the first frame 100 both roughly form a plane, and the two planes form an angle between each other, so that the side of the first frame 100 away from the second frame 200 is connected to the chassis 2, and at the same time, when the side of the second frame 200 away from the first frame 100 is connected to the chassis 2, the first frame 100, the second frame 200 and the chassis 2 together form a triangular stable structure, thereby ensuring the stability of the first frame 100 and the second frame 200 installed on the chassis 2, and at the same time improving the overall strength of the first frame 100 and the second frame 200. It should be understood that in other embodiments, when at least one of the first frame 100 and the second frame 200 forms a curved surface structure, one side of the first frame 100 is connected to the chassis 2, one side of the second frame 200 is connected to the chassis 2, and the other side of the first frame 100 and the other side of the second frame 200 are connected to each other, the purpose of forming a triangular stable structure between the first frame 100, the second frame 200 and the chassis 2 can also be achieved, that is, it can also be considered that an angle is formed between the first frame 100 and the second frame 200.

[0045] In addition, in the present embodiment, one side of the first frame 100 is used to be connected to the top surface 3 of the chassis 2, and the other side is connected to one side of the third frame 300, and the other side of the third frame 300 is used to be installed on the bottom surface 4 of the chassis 2, and an angle is formed between the first frame 100 and the third frame 300. Due to the angle formed between the first frame 100 and the third frame 300, when one side of the first frame 100 is connected to the chassis 2 and one side of the third frame 300 is connected to the chassis 2, a triangular stable structure can be formed between the first frame 100, the third frame 300 and the chassis 2, thereby ensuring the stability of the first frame 100 and the third frame 300 connected to the chassis 2, and at the same time, the overall strength of the first frame 100 and the third frame 300 can be improved.

[0046] It should be noted that, in the present embodiment, the side of the first frame 100 close to the third frame 300 is roughly set as a plane, and the side of the third frame 300 close to the first frame 100 is also roughly set as a plane, and the two planes form an angle between each other, so that the side of the first frame 100 away from the third frame 300 is connected to the chassis 2, and at the same time, when the side of the third frame 300 away from the first frame 100 is connected to the chassis 2, the first frame 100, the third frame 300 and the chassis 2 together form a triangular stable structure, thereby ensuring the stability of the first frame 100 and the third frame 300 connected to the chassis 2, and at the same time improving the overall strength of the first frame 100 and the third frame 300. It should be understood that in other embodiments, when at least one of the first frame 100 and the third frame 300 forms a curved surface structure, at this time, one side of the first frame 100 is connected to the chassis 2, one side of the third frame 300 is connected to the chassis 2, and the other side of the first frame 100 and the other side of the third frame 300 are connected to each other, the purpose of forming a triangular stable structure between the first frame 100, the third frame 300 and the chassis 2 can also be achieved, that is, it can also be considered that an angle is formed between the first frame 100 and the third frame 300.

[0047] In addition, in this embodiment, the side of the third frame 300 away from the first frame 100 is used to connect to the bottom surface 4 of the chassis 2, wherein the side of the third frame 300 away from the first frame 100 is bent toward the side of the first frame 100, so that when the first frame 100 is installed on the chassis 2, the third frame 300 can bypass the side of the chassis 2 through the bent part and extend to the bottom surface 4 of the chassis 2 and connect to the chassis 2. Among them, the bent side of the third frame 300 can be set to bypass the front end of the chassis 2, that is, the part of the third frame 300 bypassing the chassis 2 is set as the front of the unmanned vehicle, and the bumper and other anti-collision devices can be installed through the bent part. It should be understood that the third frame 300 can also bypass the side of the chassis 2 and extend to the bottom surface 4 of the chassis 2, wherein the side of the chassis 2 refers to the side of the chassis 2 corresponding to the two sides of the unmanned vehicle when the unmanned vehicle is placed normally and operates normally.

[0048] Further, in the present embodiment, the angle formed between the first frame 100 and the second frame 200 is smaller than the angle formed between the first frame 100 and the third frame 300. By making the volume of the space formed between the first frame 100 and the second frame 200 smaller than the volume of the space formed between the first frame 100 and the third frame 300, larger parts can be placed through the space formed between the first frame 100 and the third frame 300, so as to facilitate the installation of larger parts. It should be understood that in other embodiments, the angle between the first frame 100 and the second frame 200 and the angle between the first frame 100 and the third frame 300 can also be designed according to actual conditions. For example, when there are no larger parts on the chassis 2, the angle between the first frame 100 and the second frame 200 can be equal to the angle between the first frame 100 and the third frame 300, so that the strength between the first frame 100 and the second frame 200 can be equal to the strength between the first frame 100 and the third frame 300.

[0049] In addition, in the present embodiment, an obtuse angle is formed between the second frame 200 and the third frame 300, that is, an obtuse angle is formed between the side of the second frame 200 close to the first frame 100 and the side of the third frame 300 close to the first frame 100. When the second frame 200 and the third frame 300 are both connected to the chassis 2, due to the angle formed between the second frame 200 and the third frame 300, a triangular stable structure is formed between the second frame 200, the third frame 300 and the chassis 2, which can ensure the installation stability between the second frame 200 and the third frame 300, and at the same time improve the overall strength of the second frame 200 and the third frame 300.

[0050] It should be noted that, in the present embodiment, when the fuselage frame 10 is installed on the chassis 2, a triangular stable structure is formed between the first frame 100, the second frame 200 and the chassis 2, a triangular stable structure is formed between the first frame 100, the third frame 300 and the chassis 2, and a triangular stable structure is formed between the second frame 200 and the third frame 300, thereby ensuring the stability of the overall installation of the fuselage frame 10 on the chassis 2 and improving the overall strength of the fuselage frame 10.

[0051] In this embodiment, optionally, the first frame 100 includes a first mounting rod 110 and a first frame body 120, the first frame body 120 is connected to the first mounting rod 110, and the first frame body 120 and the first mounting rod 110 together form a frame shape. The first mounting rod 110 is used to be installed on the top surface 3 of the chassis 2, and the second frame 200 and the third frame 300 are both connected to the side of the first frame body 120 away from the first mounting rod 110, so that a triangular stable structure can be formed between the first frame 100, the second frame 200 and the chassis 2, and the purpose of forming a triangular stable structure between the first frame 100, the third frame 300 and the chassis 2 can also be achieved.

[0052] Further, the first frame body 120 includes a top rod 122, a first connecting rod 123 and two first side rods 121, the ends of the two first side rods 121 are respectively connected to the two ends of the first mounting rod 110, and the two ends of the top rod 122 are respectively connected to the ends of the two first side rods 121 away from the first mounting rod 110, so that the first mounting rod 110, the top rod 122 and the two first side rods 121 are collectively surrounded by a frame shape. Among them, the first mounting rod 110, the top rod 122 and the two first side rods 121 are all located in the same plane. The two ends of the first connecting rod 123 are respectively connected to the two first side rods 121, and the first connecting rod 123 is located between the top rod 122 and the first mounting rod 110. Through the arrangement of the first connecting rod 123, the ability of the two first side rods 121 to resist bending deformation can be improved, and the purpose of improving the strength of the two first side rods 121 can be achieved. Moreover, in the present embodiment, the second frame 200 and the third frame 300 are both connected to the connection between the first connecting rod 123 and the first side rod 121. The strength of the first side rod 121 can be improved by the first connecting rod 123, thereby avoiding bending deformation of the first side rod 121. At the same time, the connection stability of the second frame 200 and the third frame 300 to the first frame 100 is guaranteed, thereby ensuring the overall strength of the fuselage frame 10.

[0053] In this embodiment, optionally, the first connecting rod 123 is arranged close to the top rod 122, and there is a gap between the top rod 122 and the first connecting rod 123, that is, the distance between the first connecting rod 123 and the top rod 122 is smaller than the distance between the first connecting rod 123 and the first mounting rod 110. It should be noted that the second frame 200 and the third frame 300 are connected to the connection between the first connecting rod 123 and the first side plate, and as long as there is a gap between the first connecting rod 123 and the first mounting rod 110, the purpose of forming a triangular stable structure between the first frame 100, the second frame 200 and the chassis 2 can be achieved. Similarly, the purpose of forming a triangular stable structure between the first frame 100, the third frame 300 and the chassis 2 can be achieved. In this embodiment, by setting the first connecting rod 123 close to the top rod 122, the first connecting rod 123 is set on the side away from the first mounting rod 110, that is, when the second frame 200 and the third frame 300 are connected to the connection between the first connecting rod 123 and the first side rod 121, it can be regarded as that the second frame 200 and the third frame 300 are connected to the side of the first frame 100 away from the chassis 2. At this time, when the second frame 200 and the third frame 300 are both connected to the first frame 100, the overall stability between the first frame 100, the second frame 200, the third frame 300 and the chassis 2 can be guaranteed, and at the same time, a spatial volume can be formed between the first frame 100, the second frame 200, the third frame 300 and the chassis 2, which can facilitate the placement of other components on the chassis 2. It should be understood that in other embodiments, when no other components need to be installed on the chassis 2, the first connecting rod 123 can be arranged close to the first mounting rod 110, so as to reduce the space occupied by the entire fuselage frame 10 while ensuring the overall stability and strength of the fuselage frame 10.

[0054] It should be noted that, in the present embodiment, the second frame 200 and the third frame 300 are both connected to the connection between the first connecting rod 123 and the first side rod 121, and it can be regarded that the side of the second frame 200 close to the first frame 100 and the side of the third frame 300 close to the first frame 100 are connected to each other. At the same time, in the present embodiment, an obtuse angle is formed between the second frame 200 and the third frame 300, so that when the second frame 200 and the third frame 300 are both connected to the chassis 2, the purpose of forming a triangular stable structure by the second frame 200, the third frame 300 and the chassis 2 can be achieved.

[0055] Further, in the present embodiment, the second frame 200 includes a second mounting rod 210 and two second side rods 220. The ends of the two second side rods 220 are respectively connected to the two ends of the second mounting rod 210, and the other ends of the two second side rods 220 are respectively connected to the first frame 100, and the second mounting rod 210 and the two second side rods 220 form a frame shape together with the first frame 100. The second mounting rod 210 is used to be connected to the top surface 3 of the chassis 2, and in the present embodiment, the second mounting rod 210 is arranged parallel to the first mounting rod 110, so as to facilitate the installation of the first frame 100 and the second frame 200 on the chassis 2. It should be understood that in other embodiments, the arrangement of the second mounting rod 210 can be designed according to actual needs, that is, the second mounting rod 210 can also be arranged so that the straight line where the second mounting rod 210 is located forms a certain angle with the straight line where the first mounting rod 110 is located.

[0056] Optionally, in this embodiment, one end of the second side bar 220 close to the first frame 100 extends in a straight line, so that the side of the second frame 200 close to the first frame 100 is roughly formed into a plane. The second side bar 220 is bent on the side away from the first frame 100. Optionally, the side of the second side bar 220 away from the first frame 100 is bent toward the side of the first frame 100, which can facilitate the installation of the second installation bar 210 installed on the side of the second side bar 220 away from the first frame 100 and the chassis 2.

[0057] Further, in the present embodiment, the second frame 200 further includes a second connecting rod 230, and the two ends of the second connecting rod 230 are respectively connected to the two second side rods 220. The second connecting rod 230 can improve the anti-bending deformation capability of the two second side rods 220, thereby ensuring the strength of the two second side rods 220, and improving the overall stability and overall strength of the second frame 200. In the present embodiment, the second connecting rod 230 is arranged close to the second mounting rod 210. In addition, in the present embodiment, the second frame 200 further includes two supporting members 240, the two supporting members 240 are respectively connected to the two second side rods 220, and the side of the two supporting members 240 away from the second side rods 220 is used to connect to the top surface 3 of the chassis 2, thereby providing support to the second side rods 220 through the supporting members 240, further improving the overall stability of the second frame 200. The support member 240 is arranged close to the second mounting rod 210, and the support member 240 includes a plurality of first support rods 241, wherein the ends of two first support rods 241 are connected to the second side rod 220 and form an angle with the second side rod 220, and the distance between the two first support rods 241 gradually decreases from one end close to the second side rod 220 to one end away from the second side rod 220, and the two ends of at least one first support rod 241 are respectively connected to the above two first support rods 241, and the first support rod 241 is used to be connected to the top of the chassis 2, so that the plurality of first support rods 241 can provide a stable support to the second side rod 220, thereby ensuring the overall stability of the second frame 200. It should be understood that in other embodiments, the support member 240 can also include a plate-like support structure, one side of the plate-like support structure is connected to the second side rod 220, and the other side is used to be connected to the top of the chassis 2, which can also provide support to the second frame 200.

[0058] The third frame 300 includes a third mounting rod 310 and two third side rods 320, one end of the two third side rods 320 is connected to the first frame 100, and the ends of the two third side rods 320 away from the first frame 100 are bent toward the first frame 100, so that the third side rods 320 can bypass the side of the chassis 2 and extend to the bottom surface 4 of the chassis 2 and connect to the bottom surface 4 of the chassis 2. The third mounting rod 310 is connected to the end of the third side rod 320 away from the first frame 100, and the third mounting rod 310 is used to connect to the bottom surface 4 of the chassis 2. In this embodiment, the third mounting rod 310 is arranged parallel to the first mounting rod 110, which can facilitate the arrangement of the first frame 100 and the third frame 300. It should be understood that in other embodiments, the third mounting rod 310 can also form a certain angle with the first mounting rod 110.

[0059] Optionally, in this embodiment, the third side rod 320 includes a first rod segment 321, a second rod segment 322, and a third rod segment 323 that are sequentially connected. One end of the first rod segment 321 is connected to the first frame 100, and the first rod segment 321 extends in a straight line, so that the third frame 300 can form a plane on the side close to the first frame 100. The second rod segment 322 extends from the end of the first rod segment 321 away from the first frame 100 in a direction away from the first rod segment 321. When the third frame 300 is connected to the chassis 2, the second rod segment 322 extends from the top surface 3 of the chassis 2 to the bottom surface 4 of the chassis 2. The third rod segment 323 extends from the end of the second rod segment 322 away from the first rod segment 321 toward the first frame 100, so that the third rod segment 323 can extend to the bottom surface 4 of the chassis 2. The two ends of the third mounting rod 310 are respectively connected to the ends of the two third rod segments 323, and the third rod segments 323 extend to the bottom surface 4 of the chassis 2, so as to achieve the purpose of connecting the third mounting rod 310 to the bottom surface 4 of the chassis 2. The second rod segment 322 and the third rod segment 323 form the bent end of the third side rod 320 away from the first frame 100. In addition, in this embodiment, the second rod segment 322 and the third rod segment 323 both extend along a straight line. It should be understood that in other embodiments, the side of the third side rod 320 away from the first frame 100 can also extend along an arc to achieve the purpose of connecting the third mounting rod 310 connected to the end of the third side rod 320 to the bottom surface 4 of the chassis 2.

[0060] Further, the third frame 300 further includes a third connecting rod 330, the two ends of which are respectively connected to the two third side rods 320, so that the position stability of the two third side rods 320 is improved through the third connecting rod 330, and the anti-bending deformation capability of the two third side rods 320 can be improved, thereby improving the overall stability and strength of the third frame 300. Optionally, in this embodiment, the third connecting rod 330 is connected to the first rod section 321. In addition, the third frame 300 is further provided with a fourth connecting rod 340, the two ends of which are respectively connected to the two third side rods 320, and the fourth connecting rod 340 is arranged in an arched shape, so that the volume of the installation space between the third frame 300, the first frame 100 and the chassis 2 can be increased through the arrangement of the fourth connecting rod 340, thereby facilitating the installation of other components. Optionally, in this embodiment, the fourth connecting rod 340 is installed at one end of the first rod segment 321 close to the second rod segment 322, so that when the third frame 300 is installed on the chassis 2, the problem of a small installation space volume between the end with a smaller distance between the first rod segment 321 and the chassis 2 and the chassis 2 is improved. It should be understood that the arrangement of the fourth connecting rod 340 can also improve the position stability between the two third side rods 320 to a certain extent, thereby improving the ability of the third side rods 320 to resist bending deformation.

[0061] It should be noted that, in this embodiment, the end of the third side bar 320 connected to the first frame 100 is connected to the connection between the first connecting rod 123 and the first side bar 121, so that the third side bar 320, the third installation rod 310 and the first connecting rod 123 can form a frame shape together. Similarly, the end of the second side bar 220 connected to the first frame 100 is connected to the connection between the first connecting rod 123 and the first side bar 121, so that the second side bar 220, the second installation rod 210 and the first connecting rod 123 can form a frame shape together. That is, the first connecting rod 123 can provide reinforcement to the two first side bars 121, the two second side bars 220 and the two third side bars 320 at the same time. In addition, in this embodiment, the length of the first rod section 321 in the third side rod 320 is less than the length of the second side rod 220, that is, the third side rod 320 can be set as the front part of the unmanned vehicle, so that the installation space formed between the third frame 300 and the chassis 2 in the front part of the unmanned vehicle can be larger in volume, and more components can be installed. At the same time, the rear part of the unmanned vehicle can be used to set the working device, thereby ensuring the overall quality balance of the unmanned vehicle, making it easier for the unmanned vehicle to drive stably during operation, thereby avoiding the unmanned vehicle from rolling over.

[0062] In addition, optionally, in the present embodiment, the first frame 100, the second frame 200 and the third frame 300 can be connected to each other by welding or other methods. The top rod 122, the first side rod 121 and the first mounting rod 110 in the first frame 100 can be formed by bending a straight rod, and the first connecting rod 123 can be fixedly connected to the two first side rods 121 by welding or other methods. In addition, the second frame 200 and the third frame 300 can also be formed by bending a straight rod, that is, the second mounting rod 210 and the two second side rods 220 are integrally formed, and the third mounting rod 310 and the two third side rods 320 are integrally formed, which can ensure the integrity of the second frame 200 and the third frame 300, and can ensure the overall stability and strength of the second frame 200 and the third frame 300.

[0063] Please refer to Figure 1 and Figure 3 The support frame 20 is used to be connected to the top surface 3, and the support frame 20 spans the fuselage frame 10 and is located above the fuselage frame 10. That is, when the support frame 20 is installed on the top surface 3 of the chassis 2, the support frame 20 is connected to the top surface 3 and the fuselage frame 10 is located below the support frame 20.

[0064] For further information, see Figure 3 The support frame 20 includes a load-bearing frame 400 , two first brackets 500 and a plurality of second brackets 600 .

[0065] Among them, the load-bearing frame 400 is used to carry the working device, which can provide a stable load-bearing effect to the working device, and ensure that the working device can stably complete the specified work. In this embodiment, the load-bearing frame 400 is connected to each other by a plurality of support rods to form a mesh frame, so that the overall mass of the load-bearing frame is small, and at the same time, it can carry a larger working device. It should be noted that the width of the load-bearing frame 400 is greater than the width of the unmanned vehicle chassis 2 to facilitate the installation and placement of the working device. It should be understood that the setting of the load-bearing frame 400 can also be set according to actual conditions. For example, when the volume, that is, the mass, of the working device is small, a smaller load-bearing frame 400 can be selected at this time.

[0066] In addition, two first brackets 500 are arranged on the same side of the load-bearing frame 400, and the two first brackets 500 are arranged at intervals. The side of the two first brackets 500 away from the load-bearing frame 400 is used to connect to the top surface 3 of the chassis 2, and then the two first brackets 500 can provide support to the load-bearing frame 400 to ensure the overall stability of the load-bearing frame 400. It should be noted that the two first brackets 500 are respectively connected to two opposite side surfaces of the load-bearing frame 400, so as to ensure the overall stability of the load-bearing frame 400.

[0067] Optionally, the first bracket 500 includes a fourth mounting rod 510 and at least two second supporting rods 520, the ends of the at least two second supporting rods 520 are connected to the two ends of one side of the load-bearing frame 400, and the other ends of the two second supporting rods 520 are connected to the two ends of the fourth mounting rod 510, thereby forming a frame-shaped first bracket 500, wherein the fourth mounting rod 510 is used to connect the top surface 3 of the chassis 2. That is, the second supporting rods 520 connected to the two ends of the side of the load-bearing frame 400 can provide support to the load-bearing frame 400, ensure that the side of the load-bearing frame 400 can be fully supported, avoid the load-bearing frame 400 from flipping, and provide effective and stable bearing for the operating device. It should be understood that in other embodiments, the first bracket 500 may also include other second supporting rods 520, the two ends of the other second supporting rods 520 are respectively connected to the middle of the side of the load-bearing frame 400 and the middle of the fourth mounting rod 510, so as to further improve the support stability of the load-bearing frame 400. In addition, through the cooperation between the fourth mounting rod 510 and the top surface 3 of the chassis 2, the plurality of second support rods 520 connected to the fourth mounting rod 510 can simultaneously obtain stable position stability, thereby enabling the plurality of second support rods 520 to stably provide support to the load-bearing frame 400. Furthermore, the distance between the ends of the two second support rods 520 close to the load-bearing frame 400 is greater than the distance between the ends of the two second support rods 520 close to the fourth mounting rod 510, so that the length of the fourth mounting rod 510 is shorter, which is beneficial to the installation between the fourth mounting rod 510 and the chassis 2.

[0068] In addition, in this embodiment, the first bracket 500 includes a fourth mounting rod 510 and two second supporting rods 520, and the fourth mounting rod 510 and the two second supporting rods 520 are integrally formed, that is, it can be regarded as that the first bracket 500 is formed by bending a straight rod. It should be understood that in other embodiments, the connection method of the fourth mounting rod 510 and the two second supporting rods 520 in the first bracket 500 can also be achieved by a fixing method such as welding.

[0069] Further, in this embodiment, the plane where the first bracket 500 is located and the plane where the load-bearing frame 400 is located form an angle, and the distance between the two first brackets 500 gradually decreases from the side of the first bracket 500 close to the load-bearing frame 400 to the side away from the load-bearing frame 400. That is, the angle is formed between the two first brackets 500, which can prevent the load-bearing frame 400 from tilting to both sides, and further improve the stability of the load-bearing frame 400. At the same time, the angle formed between the two first brackets 500 is also convenient for the installation of the load-bearing frame 400 with a width greater than the chassis 2, so that the first bracket 500 can be adapted to the chassis 2 with a smaller width. It should be understood that the size of the angle formed between the first bracket 500 and the load-bearing frame 400 can be set according to actual conditions. For example, when the width of the load-bearing frame 400 is not much different from the width of the chassis 2, the angle between the first bracket 500 and the load-bearing frame 400 is large. On the contrary, when the width of the load-bearing frame 400 is much different from the width of the chassis 2, the angle between the first bracket 500 and the load-bearing frame 400 is small.

[0070] Please refer to Figure 1 , Figure 2 and Figure 3 , multiple second brackets 600 and the first bracket 500 are installed on the same side of the load-bearing frame 400, and the multiple second brackets 600 are located between two first brackets 500. Optionally, in this embodiment, the number of the second brackets 600 is two, and the two second brackets 600 are connected to the load-bearing frame 400 and arranged at intervals, and the two second brackets 600 are both connected to the fuselage frame 10, that is, the fuselage frame 10 and the second brackets 600 can jointly provide support to the load-bearing frame 400, thereby ensuring the overall stability of the load-bearing frame 400. It should be understood that in other embodiments, the number of the second brackets 600 can also be greater than two, and the side of the multiple second brackets 600 away from the load-bearing frame 400 is connected to the fuselage frame 10, so that the purpose of providing support to the load-bearing frame 400 by the fuselage frame 10 and the second brackets 600 can be achieved.

[0071] Optionally, in this embodiment, the two second brackets 600 are respectively connected to the second frame 200, so that the second frame 200 can provide a bearing function to the second bracket 600. Further, the two second brackets 600 are respectively connected to the two second side rods 220, so as to realize the bearing of the second bracket 600 and ensure the stability of the second bracket 600.

[0072] Optionally, the second bracket 600 includes a fifth mounting rod 610 and a third supporting rod 620, wherein the fifth mounting rod 610 is connected to the second side rod 220, and the two ends of the third supporting rod 620 are respectively connected to the fifth mounting rod 610 and the load-bearing frame 400, that is, the third supporting rod 620 can provide support to the load-bearing frame 400, thereby ensuring the overall level and overall stability of the load-bearing frame 400. It should be noted that in this embodiment, the fifth mounting rod 610 is in contact with the second side rod 220, and the fifth mounting rod 610 and the second side rod 220 are arranged in parallel. Among them, the fifth mounting rod 610 and the second side rod 220 are fixedly arranged by at least two buckles, and at least two buckles are arranged at intervals, thereby maintaining a stable state between the fifth mounting rod 610 and the second side rod 220, thereby ensuring the overall stability of the second bracket 600, so as to achieve the purpose of the second bracket 600 providing a stable support to the load-bearing frame 400. In addition, in this embodiment, when the fuselage frame 10 is installed on the chassis 2, the second side rod 220 is in a state of being tilted relative to the chassis 2, and when the fifth mounting rod 610 is connected to the second side rod 220, it is also in a state of being tilted relative to the chassis 2. In this embodiment, the level of the carrying frame 400 relative to the chassis 2 is achieved by directly connecting one end of the fifth mounting rod 610 to the carrying frame 400 and arranging the third support rod 620 at the other end of the fifth mounting rod 610, and the third support rod 620 can provide support to the carrying frame 400. It should be understood that in other embodiments, the third support rod 620 can also be arranged at both ends of the fifth mounting rod 610, and it is only necessary to ensure that the carrying frame 400 can maintain a relative level with the chassis 2 when installed on the chassis 2.

[0073] Furthermore, multiple second brackets 600 are arranged parallel to each other to provide uniform and sufficient support to the supporting frame 400 through multiple second brackets 600. That is, in this embodiment, the planes where the two second brackets 600 are located are parallel to each other, which can provide stable support for the second bracket 600 while ensuring the connection stability between the second bracket 600 and the second side rod 220, and avoiding the second bracket 600 from being offset or even detached from the second side rod 220.

[0074] It should be noted that in this embodiment, by arranging two first brackets 500 and two second brackets 600 on one side of the load-bearing frame 400, and when the fuselage frame 10 and the support frame 20 are both mounted on the chassis 2, the two first brackets 500 can provide a stable support to the load-bearing frame 400, and the two second brackets 600 are respectively connected to the two second side rods 220, so that the fuselage frame 10 can provide a certain support to the load-bearing frame 400, thereby further ensuring the overall stability of the load-bearing frame 400. In addition, while the two first brackets 500 provide a stable support to the load-bearing frame 400, the two second brackets 600 also provide a lifting and stabilizing effect on the fuselage frame 10, that is, the connection between the two second brackets 600 and the second frame 200 can realize the mutual restraint relationship between the fuselage frame 10 and the support frame 20, that is, while the fuselage frame 10 provides a support to the support frame 20 to ensure the stability of the support frame 20, the support frame 20 also provides a lifting effect to the fuselage frame 10 to ensure the stability of the fuselage frame 10.

[0075] In addition, in the present embodiment, the fuselage frame 10 and the support frame 20 are connected by circular rods, which can reduce the manufacturing cost of the fuselage frame 10 and the support frame 20, and can avoid the formation of sharp corners on the fuselage frame 10 and the support frame 20. It should be understood that in other embodiments, the fuselage frame 10 and the support frame 20 can also be made of other materials, such as aluminum alloy square steel.

[0076] In summary, the unmanned vehicle frame 1 provided in this embodiment can form a triangle through the angle formed between the first frame 100 and the second frame 200 set on the fuselage frame 10, so that when the first frame 100 and the second frame 200 are both installed on the chassis 2, the first frame 100, the second frame 200 and the chassis 2 can form a triangle, so that a triangular stable structure can be formed between the first frame 100, the second frame 200 and the chassis 2, which can improve the overall strength of the first frame 100 and the second frame 200 and ensure the overall stability of the first frame 100 and the second frame 200. Similarly, by forming an angle between the first frame 100 and the third frame 300, and when the first frame 100 and the third frame 300 are both installed on the chassis 2, a triangular stable structure can be formed between the first frame 100, the third frame 300 and the chassis 2, thereby improving the strength between the first frame 100 and the third frame 300, and thereby ensuring the stability between the first frame 100 and the third frame 300. The purpose of improving the overall strength of the unmanned vehicle frame 1 and ensuring its own stability is achieved. And the restraint relationship between the fuselage frame 10 and the support frame 20 can be achieved through the connection between the two second brackets 600 and the second frame 200, that is, the fuselage frame 10 provides support to the support frame 20 to ensure the stability of the support frame 20, and the support frame 20 also provides a pulling effect to the fuselage frame 10 to ensure the stability of the fuselage frame 10, which can further improve the overall stability of the unmanned vehicle frame 1.

One side of the first frame 100 is connected to the top surface 3 of the chassis 2, one side of the second frame 200 is connected to the top surface 3 of the chassis 2, one side of the third frame 300 is connected to the bottom surface 4 of the chassis 2, and a triangular stable structure is formed between the first frame 100, the second frame 200 and the chassis 2, a triangular stable structure is formed between the first frame 100, the third frame 300 and the chassis 2, and a triangular stable structure is formed between the second frame 200, the third frame 300 and the chassis 2. Thus, the purpose of improving the overall strength of the unmanned vehicle and ensuring the overall stability of the unmanned vehicle is achieved.
