[0029] Combine the following Figure 1-Figure 5 The embodiments of the present invention are described.

[0030] Figure 1 The overall structural schematic diagram of the frame provided by the embodiment of the utility model is illustrated. Figure 2 The schematic diagram of the structure of the crawler frame of the vehicle frame provided by the embodiment of the utility model is illustrated. Figure 1 and Figure 2 The vehicle frame provided by the embodiment of the utility model includes a vehicle frame body 100 and a track frame 200. The track frame 200 is arranged on at least one side of the vehicle frame body 100. It can be understood that in some possible embodiments, the track frame 200 is arranged on one side of the vehicle frame body 100, and in other possible embodiments, the track frame 200 is arranged on both sides of the vehicle frame body 100. The connection between the track frame 200 and the vehicle frame body 100 can be welding.

[0031] The track frame 200 includes a track frame middle beam 210 and a motor seat 230, wherein the motor seat 230 is arranged on the side of one end of the track frame middle beam 210 close to the rear of the frame, and the motor seat 230 is used to connect with the frame body 100, that is, the track frame middle beam 210 is arranged on the side of the frame body 100 through the motor seat 230. The track frame middle beam 210 is specifically a U-shaped structure, and the opening of the track frame middle beam 210 is arranged downward, and the motor seat 230 is connected to the top of the track frame middle beam 210.

[0032] The motor seat 230 includes a motor seat transverse plate 233 and a motor seat side plate 234. The motor seat side plate 234 is arranged on the frame body 100. The motor seat transverse plate 233 is arranged on the side of the motor seat side plate 234 away from the frame body 100. A first reinforcing rib 237 is arranged between the motor seat transverse plate 233 and the motor seat side plate 234. Specifically, the motor seat transverse plate 233 is a cylindrical structure, and the motor seat transverse plate 233 is arranged perpendicular to the motor seat side plate 234, so as to provide a certain space for installing the motor. In order to facilitate the installation of the motor, a plurality of threaded holes are arranged on the motor seat fixing plate 232. When installing the motor, the motor can be connected to the motor seat fixing plate 232 by bolts. The first reinforcing rib 237 is a flat structure, and the side with a larger area is arranged on the motor seat side plate 234, and the side with a smaller area is arranged along the outer contour of the motor seat transverse plate 233. Therefore, when designing the first reinforcing rib 237, it is necessary to make it compatible with the motor seat cross plate 233 to ensure the tightness of the connection between the two.

[0033] It can be understood that the frame body 100 is the main structure of the entire frame, which connects the various components tightly together to form a coordinated whole, ensuring the relative position and stability between the various components, so that the entire machine can work according to the design requirements. The frame body 100 bears all the weight and force, and serves as the installation basis for other components, providing a stable support platform. The track frame 200 contacts the ground through the track to provide the necessary driving force and traction. The main function of the motor seat 230 in the track frame 200 is to fix the motor to ensure that the motor can stably output power during operation. The motor seat 230 can be connected to the motor by bolts or other connection methods.

[0034] In this embodiment, an additional support structure is formed by arranging the first reinforcing rib 237 between the horizontal plate of the motor seat 230 and the side plate of the motor seat 230. When the motor seat 230 is subjected to the impact force from the running device or the working action, these forces will first act on the horizontal plate of the motor seat 230, and then be dispersed and transmitted to the side plate of the motor seat 230 through the reinforcing ribs, and finally transmitted to the frame body 100. In this process, the provision of the first reinforcing rib 237 increases the rigidity of the structure, thereby reducing the strength difference at the connection between the frame body 100 and the motor seat 230, thereby avoiding excessive stress concentration at the connection between the motor seat 230 and the frame body 100.

[0035] Furthermore, in this embodiment, by setting the motor seat side plate 234 on the frame body 100, the contact between the motor seat 230 and the frame body 100 is more complete, forming a larger stress dispersion surface. When the impact force acts on the motor seat 230, these forces will be more evenly transmitted to the frame body 100 along the surface, rather than concentrated at a certain point or a small area. This stress dispersion effect can also help reduce the stress concentration at the connection between the frame body 100 and the motor seat 230, and improve the stability and durability of the connection.

[0036] Figure 3 The schematic diagram of the structure of the motor seat of the frame provided by the embodiment of the utility model is illustrated. Figure 3 In some embodiments of the present invention, the motor base transverse plate 233 is provided with a second reinforcing rib 238 , and the first reinforcing rib 237 and the second reinforcing rib 238 are respectively located on two sides of the motor base transverse plate 233 .

[0037] In the above structure, by respectively providing the first reinforcing rib 237 and the second reinforcing rib 238 on both sides of the motor seat cross plate 233, the stress generated when the motor is working can be dispersed more effectively. When the motor is working, the force and vibration generated by it will be transmitted to the motor seat 230, and the first reinforcing rib 237 and the second reinforcing rib 238 on both sides can disperse these stresses to a larger area, thereby reducing the risk of local stress concentration and extending the service life of the components. Secondly, the provision of the second reinforcing rib 238 not only enhances the structural strength of the motor seat 230 itself, but also indirectly improves the connection strength between the motor seat 230 and the frame body 100. Because the provision of the second reinforcing rib 238 enables the motor seat 230 to better transmit the force to the frame body 100 when subjected to external force, reducing the risk of breakage or loosening due to insufficient strength at the connection.

[0038] Specifically, the shape of the second reinforcing rib 238 includes but is not limited to an L-shaped structure, and may also be other shapes, such as a trapezoid, a triangle, an arc or other irregular shapes, as long as it can better adapt to the motor seat cross plate 233 and have a more perfect stress distribution. In some possible embodiments, the second reinforcing rib 238 can be designed as a grid-like structure, which not only enhances the overall rigidity of the product, but also has a certain aesthetics. Furthermore, in order to reduce air resistance, the second reinforcing rib 238 can also be designed to be streamlined, and its direction needs to be adapted to the walking direction of the frame so that it can reduce wind resistance during walking. Further, the connection between the second reinforcing rib 238 and the motor seat cross plate 233 and the motor seat side plate 234 should be designed with rounded corners or bevels to eliminate stress concentration and improve plastic flow. And the width of the connection should be appropriate, not too wide or too narrow, to prevent shrinkage marks or deformation.

[0039] Reference Figure 3 In some embodiments of the present invention, a plurality of second reinforcing ribs 238 are provided, and the plurality of second reinforcing ribs 238 are arranged at intervals. Specifically, three second reinforcing ribs 238 can be provided, but are not limited to three, and the number can be adjusted accordingly according to actual conditions. It should be noted that the second reinforcing rib 238 is provided corresponding to the first reinforcing rib 237, that is, the second reinforcing rib 238 is arranged at the connection portion between the first reinforcing rib 237 and the motor seat cross plate 233, so that the two can have corresponding support strengths, thereby reducing stress while increasing strength.

[0040] Reference Figure 2In some embodiments of the utility model, the motor seat 230 also includes a motor seat bottom plate 231 and a motor seat fixing plate 232. The motor seat fixing plate 232 is arranged on the side of the motor seat transverse plate 233 away from the motor seat side plate 234. The motor seat bottom plate 231, the motor seat fixing plate 232, the motor seat transverse plate 233 and the motor seat side plate 234 cooperate to form a first cavity. The first cavity is provided with an opening, which is used for the transmission connection between the motor and the track.

[0041] Specifically, the motor base plate 231 is arranged at the bottom, and the bottom of the motor base plate 231 is tightly arranged with the top of the track frame middle beam 210. One side of the motor base plate 231 is arranged vertically with the motor base side plate 234, and the bottom of the motor base fixing plate 232 is arranged at the top of the motor base plate 231. The motor base transverse plate 233 is an arc-shaped structure, and then the motor base base plate 231, the motor base fixing plate 232, the motor base transverse plate 233 and the motor base side plate 234 cooperate to form a cylindrical or approximately cylindrical first cavity. It can be understood that the motor base fixing plate 232 and the motor base side plate 234 serve as the two end faces of the first cavity, and the motor base transverse plate 233 and part of the motor base base plate 231 serve as the side of the first cavity. Two holes are correspondingly arranged on the motor base fixing plate 232 and the motor base side plate 234, and both holes are connected to the first cavity. When the motor is installed, the outer shell of the motor can be threadedly matched with the motor seat fixing plate 232, and the output shaft of the motor can pass through the two holes to achieve transmission connection with the crawler track.

[0042] Reference Figure 2 In some embodiments of the present invention, the motor seat side plate 234 is provided with a third reinforcing rib 235 and a fourth reinforcing rib 236, and the third reinforcing rib 235 and the fourth reinforcing rib 236 are arranged along two different directions.

[0043] Specifically, the third reinforcing rib 235 and the fourth reinforcing rib 236 can be arranged in a T shape and provided at the top of the motor seat side panel 234 on the side where the first reinforcing rib 237 is provided. Here, the third reinforcing rib 235 and the fourth reinforcing rib 236 are connected to the wing box 300, thereby strengthening the connection strength between the motor seat side panel 234 and the wing box 300.

[0044] Reference Figure 2 In some embodiments of the present invention, the track frame 200 further includes a front support 220 , which is disposed at one end of the track frame middle beam 210 away from the rear of the frame, and the front support 220 is used to connect with the frame body 100 .

[0045] In the above structure, the front support 220 can be used as another connection point to firmly fix the track frame middle beam 210 to the frame body 100. This arrangement enhances the stability of the entire frame, reduces vibration and displacement, and ensures the smooth operation of the machine during operation. The front support 220 and the motor seat 230 jointly bear the load generated by the motor and its transmission system, effectively dispersing the single-point force and reducing the risk of local stress concentration. This helps to extend the service life of the components and improve the reliability of the entire machine.

[0046] Specifically, the crawler frame 200 includes a connection seat and a connection wing. The connection seat is L-shaped and is arranged at the corner of the bottom of the frame body 100. One surface of the connection seat is connected to the bottom surface of the frame body 100, and the other surface is connected to the side surface of the frame body 100, so as to increase the strength of the connection with the frame body 100. The connection wing is a semi-ring structure, and its specific shape should be adapted to the shape of the crawler frame center beam 210, so as to enhance the tightness of the connection between the two.

[0047] Figure 4 The schematic structural diagram of the wing box of the vehicle frame provided by the embodiment of the utility model is illustrated.

[0048] Reference Figure 2 and Figure 4 In some embodiments of the present invention, a wing box 300 is further included. The wing box 300 and the track frame 200 are arranged on the frame body 100 in a one-to-one correspondence. The track frame 200 and the wing box 300 are located on the same side of the frame body 100. The wing box 300 includes a wing box front plate 310, a first wing box side plate 320, a wing box rear plate 330 and a second wing box side plate 340. The wing box front plate 310, the first wing box side plate 320, the wing box rear plate 330 and the second wing box side plate 340 cooperate to form a second cavity. The wing box front plate 310 is connected to the motor seat side plate 234. The second cavity is through-connected from top to bottom. The wing box front plate 310 is an arc-shaped structure and is provided with a stress relief groove 311. By providing the stress relief groove 311, the stress concentration of the wing box 300 can be reduced.
