[0010] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0011] In related technologies, the chassis of tracked transporters is usually an integrated structure. When tracked transporters travel on uneven roads, such as crater-shaped surfaces, especially uneven roads, the vehicle is prone to tilting due to the tilt of the road surface. Therefore, how to reduce the tilting of tracked transporters on uneven roads is an urgent technical problem to be solved.

[0012] In this invention, an XY coordinate system is established for the tracked transport vehicle frame structure, with reference to... Figures 1 to 11 As shown, the direction pointed to by the X arrow can represent the first direction, and the direction pointed to by the Y arrow can represent the second direction.

[0013] In view of the above-mentioned technical problems, the first aspect of the present invention provides a tracked transport vehicle frame structure, with reference to... Figures 1 to 11As shown, the tracked transport vehicle frame structure includes a first frame 1, a second frame 2, and an articulated shaft 3. The first frame 1 includes a first beam body 110 and a first connecting beam 120. There are two first beam bodies 110, which are spaced apart along the Y direction and extend along a first direction perpendicular to the X direction. The two ends of the first connecting beam 120 are respectively connected to the two first beam bodies 110, and the first connecting beam 120 includes a first mounting hole 121 extending along the first direction. The second frame 2 includes a second beam body 210 and a second connecting beam 220. There are two second beam bodies 210, which are spaced apart along a second direction and extend along the first direction. The two ends of the second connecting beam 220 are respectively connected to the two second beam bodies 210, and the second connecting beam 220 includes a second mounting hole 221 extending along the first direction. The articulated shaft 3 passes through the first mounting hole 121 and the second mounting hole 221, so that the second frame 2 rotates relative to the first frame 1 about the articulated shaft 3 as its axis.

[0014] Through the above technical solution, namely the tracked transport vehicle frame structure provided by the present invention, this tracked transport vehicle frame structure can be applied to a tracked transport vehicle. Specifically, the first beam body 110 of the first frame 1 is connected to the track frame of the tracked transport vehicle, and the second beam body 210 of the second frame 2 can be used to connect the cargo box of the tracked transport vehicle. That is, the first frame 1 and the second frame 2 are separate units, and are rotatably connected by a hinge shaft 3. Specifically, after the hinge shaft 3 passes through the first mounting hole 121 and the second mounting hole 221 respectively, it can connect the first frame 1... Connected to the second frame 2, when the tracked transporter bumps along uneven roads, the second frame 2 can rotate relative to the first frame 1 at a certain angle through the hinge shaft 3. When passing over uneven roads, the second frame 2 can also tilt relative to the first frame 1 at a certain angle according to the slope angle of the road, thus playing a certain stabilizing role. This reduces or prevents the danger of vehicle tilting due to the shift of the center of gravity of the tracked transporter's frame structure, and improves the safety performance of the tracked transporter when driving on uneven roads.

[0015] It should be noted that the first frame 1 mentioned in the above embodiments is usually located below the frame structure, that is, as the lower frame to connect to the tracks of the tracked transport vehicle. The second frame 2 is usually located above the frame structure, that is, above the first frame 1, as the upper frame to connect to the cargo box of the tracked transport vehicle. Furthermore, the spacing between the two first beam bodies 110 in the second direction is also greater than the spacing between the two second beam bodies 210 in the second direction. Correspondingly, the extension length of the first connecting beam 120 in the second direction is also greater than the extension length of the second connecting beam 220 in the second direction. In this arrangement, when the hinge shaft 3 passes through the first mounting hole 121 and the second mounting hole 221 to realize the rotational connection between the second frame 2 and the first frame 1, the upper second frame 2 will not have an excessively large rotation angle relative to the first frame 1. That is, the first connecting beam 120 extending along the second direction can play a certain limiting role on the two second beam bodies 210 arranged at intervals along the second direction, thereby preventing the second frame 2 from having an excessively large rotation angle relative to the first frame 1 and still causing the vehicle to tilt.

[0016] To prevent the second frame 2 from tilting due to excessive rotation angle relative to the first frame 1, the rotation angle of the second frame 2 relative to the first frame 1 can be limited. For example, the tilt angle of the second frame 2 relative to the first frame 1 with the hinge shaft 3 as the axis can not exceed 15°. Under these conditions, when the tracked transport vehicle passes over bumpy roads, the second frame 2 can rotate a certain angle relative to the first frame 1 to maintain stability according to the tilt angle of the ground, without causing the tracked transport vehicle to tilt due to excessive rotation angle of the second frame 2 relative to the first frame 1, thus improving the safety performance of the tracked transport vehicle frame structure during use.

[0017] In some implementations, reference Figures 1 to 11 As shown, the second connecting beam 220 includes a first plate 222 and a second plate 223. There are two second plates 223, which are arranged at intervals along the first direction. One end of each of the two second plates 223 is connected to the first plate 222. A second mounting hole 221 is provided in the second plate 223. The first connecting beam 120 is located between the two second plates 223.

[0018] In the above manner, when the first connecting beam 120 and the second connecting beam 220 are connected by the hinge shaft 3, the hinge shaft 3 passes sequentially through the second mounting holes 221 of the two second plates 223 and the first mounting hole 121 of the first connecting beam 120. The two second plates 223 can axially limit the first connecting beam 120, thereby reducing the axial movement of the first connecting beam 120 relative to the second connecting beam 220, improving the overall stability of the tracked transporter frame structure. Furthermore, when the first connecting beam 120 is relative to the second connecting beam 220... When the second connecting beam 220 rotates, it can also be limited to a certain extent by the first plate 222 to prevent the first frame 1 and the second frame 2 from rotating too much and causing the vehicle to tilt. That is, when the first connecting beam 120 rotates to the limit angle relative to the second connecting beam 220, the outer side wall of the first connecting beam 120 will partially fit against the surface of the first plate 222 to prevent the first connecting beam 120 and the second connecting beam 220 from continuing to rotate, thereby improving the overall stability of the tracked transport vehicle frame structure when passing through uneven road surfaces.

[0019] Further, refer to Figures 1 to 11 As shown, the second connecting beam 220 also includes a second limiting member 224 connected to the first plate 222; the first connecting beam 120 includes a first limiting member 122. When the first frame 1 and the second frame 2 rotate relative to each other to a first preset angle, the first limiting member 122 contacts the second limiting member 224 to restrict the rotation of the first frame 1 relative to the second frame 2.

[0020] In the above manner, when the first frame 1 rotates relative to the second frame 2 to a first preset angle, which corresponds to the aforementioned limit angle, the rotation of the first frame 1 and the second frame 2 can be locked by the contact between the first limiting member 122 and the second limiting member 224, so as to prevent the first frame 1 and the second frame 2 from tilting due to excessive rotation angle. The first preset angle can be 15° as mentioned in the above embodiment. That is, when the rotation angle of the first frame 1 relative to the second frame 2 is 15° or there is a tendency to rotate to a larger angle, the first limiting member 122 can contact the second limiting member 224 to lock the first frame 1 and the second frame 2, thereby preventing the vehicle from tilting.

[0021] It should be noted that the first limiting member 122 and the second limiting member 224 can adopt any suitable structure to achieve the rotational locking of the first frame 1 and the second frame 2. For example, the first limiting member 122 can be a groove structure formed on the surface of the first connecting beam 120. Correspondingly, the second limiting member 224 can be a protrusion structure connected to the first plate 222 and protruding relative to the first plate 222. When the first frame 1 rotates relative to the second frame 2 by a first preset angle, the protrusion structure can be inserted into the groove structure to achieve the rotational locking of the first frame 1 and the second frame 2. Alternatively, the first limiting member 122 and the second limiting member 224 can also adopt other structural forms to cooperate for unlocking and locking. The specific structure of the first limiting member 122 and the second limiting member 224 will be described in detail below, and will not be elaborated on here.

[0022] Furthermore, the aforementioned first preset angle is not limited to the 15° specified in the above embodiments. In particular, any suitable angle can be selected according to the structural form and specific size of the first frame 1 and the second frame 2, such as 5°, 10°, 20°, 25° or other angles. This embodiment does not specifically limit this.

[0023] In some implementations, reference Figures 1 to 11 As shown, the first connecting beam 120 also includes an extension 123 extending along the second direction. The first limiting member 122 is configured as a first boss formed on the surface of the extension 123. The second limiting member 224 is configured as a second mating surface formed on the surface of the first plate 222. The second mating surface is disposed opposite to the first boss.

[0024] In the above manner, when the first frame 1 rotates relative to the second frame 2 to a first preset angle, that is, rotates to the limit angle, the second mating surface on the first plate 222 will fit against the first protrusion protruding from the surface of the extension. In this arrangement, that is, when the first limiting member 122 is the first protrusion and the second limiting member 224 is the second mating surface, when the first frame 1 rotates relative to the second frame 2 to the limit angle, the second mating surface will directly fit against the upper surface of the first protrusion, so that the second frame 2 will no longer rotate relative to the first frame 1 to a larger angle, reducing the possibility of tilting. Through the cooperation between the second mating surface and the first protrusion, a simpler locking can be achieved. That is, the structure of the protrusion abutting against the surface is simple, and the locking and unlocking process is quick and convenient, which improves the stability of the tracked transport vehicle frame structure when passing through uneven road surfaces.

[0025] When tracked transport vehicles traverse uneven surfaces, they typically tilt in both the left and right directions. To better handle these tilts, refer to... Figures 1 to 11As shown, there are two first bosses arranged at intervals along the second direction, and the first mounting hole 121 is located between the two first bosses; there are two second mating surfaces, and the two second mating surfaces correspond one-to-one with the two first bosses; on the projection surface of the first direction, the second mounting hole 221 is located between the two second mating surfaces.

[0026] By means of the above method, that is, by the one-to-one matching of the two second mating surfaces with the two first bosses, the tracked transport vehicle can be better stabilized when it tilts to the left and right. That is, no matter whether the tracked transport vehicle tilts to the left or right to the first preset angle, that is, the extreme angle, there will always be a first boss in contact with a second mating surface to prevent the first frame 1 and the second frame 2 from continuing to rotate and tilting at a larger angle.

[0027] In some implementations, reference Figures 1 to 11 As shown, there are multiple first connecting beams 120, which are arranged at intervals along the first direction; there are multiple second connecting beams 220, which correspond one-to-one with the number of first connecting beams 120, and are arranged at intervals along the first direction.

[0028] In the above manner, the first frame 1 and the second frame 2 can be connected one-to-one by multiple first connecting beams 120 and multiple second connecting beams 220, which together improves the overall structural strength of the tracked transport vehicle frame structure. Specifically, the first frame 1 improves its structural strength through two first beam bodies 110 and multiple first connecting beams 120, and the second frame 2 improves its structural strength through two second beam bodies 210 and multiple second connecting beams 220.

[0029] In the above arrangement, the number of hinge shafts 3 can be one or more. In one embodiment, such as... Figure 8 As shown, the number of hinge shafts 3 can be one, and one hinge shaft 3 can pass through the first mounting holes 121 of multiple first connecting beams 120 and the second mounting holes 221 of multiple second connecting beams 220.

[0030] In the above arrangement, that is, by passing a single hinge shaft 3 through multiple first mounting holes 121 and second mounting holes 221, the assembly process of the first frame 1 and the second frame 2 can be made simpler. That is, by simply passing the hinge shaft 3 through multiple first mounting holes 121 and multiple second mounting holes 221 at once, the assembly of the first frame 1 and the second frame 2 can be realized and the flexible rotational connection between the two can be ensured.

[0031] In another implementation, namely as Figure 1As shown, the number of hinge shafts 3 can also be multiple, that is, each hinge shaft 3 is correspondingly inserted into the first mounting hole 121 of a single first connecting beam 120 and the second mounting hole 221 of a single second connecting beam 220.

[0032] In this way, the number of articulated shafts 3 can also correspond one-to-one with the number of multiple first connecting beams 120 or multiple second connecting beams 220. Although this method increases the complexity of assembling the first frame 1 and the second frame 2, it can reduce the difficulty of maintenance when the tracked transport vehicle frame structure is disassembled and repaired later. For example, if the first frame 1 and the second frame 2 are stuck in rotation, and the cause of the stuckness is a problem with the articulated shaft 3, only the problematic articulated shaft 3 needs to be replaced to quickly repair the tracked transport vehicle frame structure, without having to disassemble, inspect and replace all the articulated shafts 3, thus improving efficiency.

[0033] Furthermore, by connecting multiple hinge shafts 3, some space between the first frame 1 and the second frame 2 can be saved, reducing the space occupied by the tracked transport vehicle frame structure.

[0034] In some implementations, reference Figures 1 to 11 As shown, the second frame 2 also includes a support platform 230 connected to the second beam body 210, and the support platform 230 is located on the side of the second frame 2 away from the first frame 1.

[0035] In this way, the support platform 230 can support the cargo box of the tracked transport vehicle, that is, it can support the cargo box more stably.

[0036] A second aspect of the present invention provides a tracked transport vehicle, with reference to Figures 1 to 11 As shown, the tracked transport vehicle includes a cargo box 4, a track drive structure 5, and the tracked transport vehicle frame structure mentioned in the above embodiments. The cargo box 4 is connected to the second frame 2 of the tracked transport vehicle frame structure, and the track drive structure 5 is connected to the first frame 1. It also possesses all the beneficial effects described in the above embodiments. Furthermore, the tracked transport vehicle using this tracked transport vehicle frame structure can also reduce side tilting on uneven road surfaces, i.e., as... Figure 9 and Figure 10 As shown, when the tracked transport vehicle travels on a flat road surface... Figure 9 The state shown indicates that when the tracked transport vehicle traverses the uneven, crater-shaped ground... Figure 10 In this state, the first frame 1 can tilt relative to the second frame 2, thereby maintaining the tracked transport vehicle from tilting and improving stability during operation.

[0037] Furthermore, refer to Figure 11As shown, the track drive structure 5 can adopt any component in the related technology that can drive the track for transmission. The track drive structure 5 can be composed of a track body, a drive motor, at least one drive wheel and multiple driven wheels. The track body is wrapped around the drive wheel and multiple driven wheels. The drive motor drives the drive wheel to rotate, and the drive wheel drives the multiple driven wheels to achieve the operation of the track body, so as to drive the tracked transport vehicle to move as a whole.

[0038] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope of protection claimed by the present invention.
