Description

Technical Field

[0001] This utility model relates to the field of vehicles, and more specifically, to a support structure and vehicle for connecting a rigid frame and a power mechanism. Background Technology

[0002] Mining vehicles, especially those in the mining industry, operate under harsh conditions on rough and uneven roads, subjecting their components to severe vibrations and impacts. They endure these shocks and vibrations over long periods. The introduction of electric motors and corresponding gearboxes into mining vehicles has improved their torque and reliability. The support structure connecting these power mechanisms (motor and gearbox) to the chassis determines the stress characteristics, operational smoothness, and degree of vibration and impact resistance of the power mechanism.

[0003] Referring to CN221213466U, a drive motor mounting bracket and a new energy mining car are disclosed, including a mounting plate and a fixing plate. The mounting plate is in the form of a curved plate and is arranged on the radial circumferential surface of the drive motor. The drive motor is fixed to the mounting plate by fasteners. The fixing plate is installed on the outward-facing side of the mounting plate and is fixed to a rigid frame by connectors. This utility model optimizes the shape and structure of the existing drive motor mounting bracket, making the load on the connecting bolts and the drive motor housing more evenly and reasonably distributed.

[0004] This type of support reduces the risk of connecting bolt breakage and drive motor housing tearing; however, there is still room for improvement in the design of its reinforcing rib structure. This application aims to provide a support structure and vehicle for connecting a rigid frame and a powertrain, thereby improving the strength of the support structure and enhancing the overall reliability of the vehicle. Summary of the Invention

The mounting plate has a first mounting hole for mounting the power unit, and the fixing plate has a second mounting hole for mounting the rigid vehicle frame. The mounting plate has a mounting surface and a supporting surface arranged opposite to each other.

[0007] Furthermore, the reinforcing plate is provided with an adjacent first connecting edge and a second connecting edge, the first connecting edge being in contact with the fixing plate, and the second connecting edge being in contact with the supporting surface and matching the shape of the supporting surface.

[0008] Furthermore, the bending area divides the mounting plate into an upper region and a lower region, with the first mounting hole located in the lower region of the mounting plate and the fixing plate located in the upper region of the mounting plate.

[0009] Furthermore, from the bending area to the bottom of the reinforcing plate, the second connecting edge is parallel to its opposite edge; from the bending area to the top of the reinforcing plate, the distance between the second connecting edge and its opposite edge gradually increases.

[0010] Furthermore, both the reinforcing plate and the fixing plate have bevels for welding on their contact edges where they connect with the mounting plate, and the reinforcing plate has a bevel for welding on its contact edge where it connects with the fixing plate.

Detailed Implementation

[0026] 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, and 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.

[0027] It should be noted that in this article, relational terms such as “first” and “second” are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0028] Please refer to Figures 1 to 6 This embodiment provides a support structure for connecting the rigid frame 10 and the power mechanism.

[0029] Reference Figure 1 , Figure 2 and Figure 7 As shown, the support structure includes a mounting plate 1, a fixing plate 2, and a reinforcing plate 3. The mounting plate 1, fixing plate 2, and reinforcing plate 3 are rigid plates. The mounting plate 1 has a through first mounting hole 4 for connecting an electric drive component; the first mounting hole 4 is a plurality of holes arranged in an array. The support structure is connected to a power mechanism, including a motor 11 or a gearbox, via the first mounting hole 4 on the mounting plate 1.

[0030] Reference Figure 1 , Figure 3 and Figure 4 As shown, the fixing plate 2 has a through second mounting hole 5 for connecting the rigid frame 10. The fixing plate 2 is an independent plate body relative to the mounting plate 1. The fixing plate 2 is fixedly connected to the support surface 15. In the attached figure, the fixing plate 2 is located at the top of the rear side of the mounting plate 1.

[0031] Mounting plate 1, as a plate body, has two oppositely arranged surfaces, namely mounting surface 14 and supporting surface 15. A power mechanism is mounted on mounting surface 14. Through a bending process, mounting plate 1 is bent towards mounting surface 14, forming a bending area 6. Figure 1The bending region 6 is shown as bending towards the front of the mounting plate 1. The bending region 6 is located near the center of the mounting plate 1, dividing the mounting plate 1 into an upper region and a lower region, with an obtuse angle between the two plates in the upper and lower regions. In some preferred embodiments, the bending region 6 should be parallel to the top and bottom edges of the mounting plate 1. It should be understood by those skilled in the art that the bending region 6 can be a zigzag line or a curved line. A first mounting hole 4 is provided on the lower region of the mounting plate 1. A fixing plate 2 is fixedly connected to the mounting plate 1 on the support surface 15, and the fixing plate 2 is located in the upper region of the mounting plate 1 and close to the top of the mounting plate 1. In some embodiments, the top of the mounting plate 1 is fixedly connected to the fixing plate 2 via the support surface 14. The support surface 15 is also connected to a reinforcing plate 3, which has an adjacent first connecting edge 7 and a second connecting edge 8. The first connecting edge 7 is used to fit with the fixing plate 2, and the second connecting edge 8 is fitted with the mounting plate 1. Since the mounting plate 1 has a bending area 6, the second connecting edge 8 adapts to the arc shape of the support surface 14 and extends from the reinforcing plate 3 to the bottom of the mounting plate 1.

[0032] The advantages of this arrangement are as follows: First, the reinforcing plate 3 can simultaneously act on the upper and lower parts of the bending area 6 of the mounting plate 1, as well as between the mounting plate 1 and the fixing plate 2. The reinforcing plate 3, as a single plate, simultaneously serves as two reinforcing ribs, strengthening both the upper and lower parts of the bending area 6 of the mounting plate 1 and the area between the mounting plate 1 and the fixing plate 2. This achieves component reuse, reduces the number of components, and simplifies the process complexity. Second, the reinforcing plate 3 is located on the back side of the bending area 6 of the mounting plate 1. Compared to the inside (front) side of the bending area 6, this changes the tension to pressure. The welded area, originally a weak point, is most prone to damage and failure. This application eliminates this defect. Placing the reinforcing plate 3 on the back (rear) side reduces the requirements for connection quality, thereby improving reliability. This also makes the mounting surface 14 of the mounting plate 1 flatter, facilitating the installation of the motor or gearbox.

[0033] It is worth noting that the normals of the mounting plate 1 and the fixing plate 2 in the upper region are not required to be perpendicular. In the case where the included angle between the two normals is not perpendicular, the reinforcing plate 3 provided on the mounting plate 1 and the fixing plate 2 adapts to the above-mentioned angle change and provides corresponding first connecting edge 7 and second connecting edge 8 to adapt to the shape of the corresponding cross-section.

[0034] As will be understood by those skilled in the art, there may be several reinforcing plates 3, which are deployed in the width direction of the mounting plate 1 and the fixing plate 2, and avoid the first mounting hole 4 and the second mounting hole 5. The following description of the reinforcing plates 3 assumes that there are two reinforcing plates 3, which exist at the left and right ends of the mounting plate 1 and the fixing plate 2.

[0035] refer to Figure 1 As shown, in some embodiments, the mounting plate 1, the fixing plate 2, and the reinforcing plate 3 are each an independent plate. The reinforcing plate 3 and the fixing plate 2 have bevels 9 for welding at their contact edges (second connecting edge 8) with the mounting plate 1. The reinforcing plate 3 also has bevels 9 for welding at its contact edge with the fixing plate 2 (first connecting edge 7). The components are connected by welding through these bevels 9. To further improve the supporting effect of the reinforcing plate 3 on the mounting plate 1, a second connecting edge 8 with a shape adapted to the curved shape of the mounting plate 1 is provided. It is tightly connected to the mounting plate 1 from top to bottom, reducing the pressure on the contact surface between the reinforcing plate 3 and the mounting plate 1. Specifically, from the corresponding bending area 6 to the bottom of the reinforcing plate 3, the second connecting edge 8 is parallel to its opposite edge; from the corresponding bending area 6 to the top of the reinforcing plate 3, the distance between the second connecting edge 8 and its opposite edge gradually increases. In some other embodiments, the reinforcing plate 3 is welded to the mounting plate 1 above and below the bending area 6 and to the fixing plate 2. The difference between this method and the previous embodiment is that the previous embodiment was welded on the entire first connecting edge 7 and the second connecting edge 8, while this embodiment uses point welding or segmented welding, which provides deformation allowance for welding and reduces the requirements for welding process.

[0036] refer to Figure 5 As shown, in some other possible embodiments, the reinforcing plate 3 and the fixing plate 2 can be an integral structure, with a first bend 16 connecting the fixing plate 2 and the reinforcing plate 3. In the aforementioned embodiments, the mounting plate 1 and the fixing plate 2, as well as the mounting plate 1 and the reinforcing plate 3, are still connected by welding and have a bevel 9.

[0037] refer to Figure 6 As shown, in some other possible embodiments, the fixing plate 2 and the mounting plate 1 can be an integral structure, with a second bend 17 connecting the fixing plate 2 and the mounting plate 1. The contact edges of the reinforcing plate 3 with the mounting plate 1 and with the fixing plate 2 still have bevels 9 for welding.

[0038] refer to Figure 7 As shown, based on the support structure of this application, a vehicle is also provided, including a rigid frame 10, a power mechanism and the aforementioned support structure for connecting the rigid frame 10 and the power mechanism. The power mechanism is fixedly connected to the mounting surface 14 of the mounting plate 1. The surface of the power mechanism near the mounting plate 1 matches the shape of the mounting surface 14. The fixing plate 2 is fixedly connected to the rigid frame 10.

[0039] The power mechanism includes a motor 11 or a gearbox. The motor 11 converts electrical energy into mechanical kinetic energy, providing torque. The gearbox receives the torque and performs torque conversion, transforming the rated speed and torque output by the motor 11 into high-speed low-torque or low-speed high-torque as needed.

[0040] In addition, by Figure 3 and Figure 4 As can be seen, the second mounting hole 5 is designed as a waist hole, thus providing some adjustment space, better compatibility, and reducing the requirements for assembly precision. The second mounting hole 5 is fixedly connected to the rigid frame 10 by fasteners 12, vibration damping components 13 such as elastic washers, and the fasteners 12 pass through the second mounting hole 5. This reduces vibration transmission between the power mechanism and the frame, maintaining a longer service life of the power mechanism.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
