[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0021] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0022] It should be understood that the terms such as "having", "including" and "comprising" used in the embodiments of the present application do not exclude the existence or addition of one or more other elements or their combinations. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back ...) are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture. If the specific posture changes, the directional indication also changes accordingly. When an element is referred to as "fixed on" or "set on" another element, it can be directly on another element or there may be a centering element at the same time. When an element is referred to as "connecting" another element, it can be directly connected to another element or it can also be indirectly connected to another element through a centering element. The description of the embodiments of the present application involving "first", "second", etc. is only for descriptive purposes, and cannot be understood as indicating or implying its relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features.

[0023] It should be noted that the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0024] like Figure 1-4 As shown, an embodiment of the present application provides a battery pack support for an off-road mining dump truck, including: a bracket main box 3, which is a box-shaped structure that is thick in the middle and gradually thinner at both ends, and a mounting plate 301 is connected to the lower part of the bracket main box 3, and the mounting plate 301 is used to be connected to the frame longitudinal beam 1, and an arc transition is formed between the bracket main box 3 and the mounting plate 301; a cover plate 2, which covers the upper part of the bracket main box 3 and is welded to the bracket main box 3, and a fixing hole 202 for fixing the battery pack is provided on the cover plate 2.

[0025] Exemplarily, the interior of the bracket main box 3 is hollow and symmetrical on the left and right, and the thickness continuously becomes thinner from the middle to the left and right ends to achieve an equal strength design; compared with the existing technology, such a design occupies less space in the left and right directions, and has an overall weight reduction effect without affecting the load-bearing capacity, and has a small redundancy.

[0026] Exemplarily, the mounting plate 301 may be welded to the bottom of the bracket main box 3 or formed integrally with the bracket main box 3 .

[0027] Exemplarily, the size of the connection part between the bracket main box 3 and the mounting plate 301 gradually decreases and has an arc transition, which can reduce stress concentration, improve the stress condition, and increase the service life of the product; and the connection part can be designed to different heights according to actual requirements, with little impact on the load-bearing of the mounting plate 301 and the frame, and strong spatial adaptability.

[0028] For example, see Figure 1 The mounting plate 301 is provided with fixing holes, and the surface of the frame longitudinal beam is also provided with corresponding fixing holes for achieving connection with the frame longitudinal beam 1.

[0029] Exemplarily, the cover plate 2 just covers and connects to the upper portion of the bracket main box 3 to form a semi-enclosed box-like structure, thereby improving the integrity of the battery pack support and the supporting strength.

[0030] Compared with the equal-section design in the prior art and the battery pack support connected to both sides of the longitudinal beam 1, this embodiment can significantly save left and right space, occupy less space, and have high space utilization, forming an overall box-type structure with high supporting strength, a hollow interior, and a variable-section design, which has a significant weight reduction effect.

[0031] In another embodiment, a plurality of round-shaped ribs 302 are provided inside the bracket main box 3; illustratively, the bottom of the round-shaped rib is connected to the bottom of the bracket main box 3, and the side walls on both sides of the round-shaped rib are connected to the inner side walls of the bracket main box 3, so as to further enhance the overall strength and rigidity of the bracket main box 3 and the battery pack support; in addition, a hole is provided in the middle of the round-shaped rib 302 to further enhance the weight reduction effect.

[0032] In another embodiment, the edges of both sides of the cover plate 2 are bent toward the bracket main box 3 to form a bent portion 201 , which can improve the support strength and rigidity of the cover plate 2 .

[0033] like Figure 4-5 As shown, in another embodiment, it also includes a three-dimensional reinforcing rib 4, which is obtained by bending a flat plate, and the outer peripheral edge of the three-dimensional reinforcing rib 4 forms a first welding section, a second welding section and a third welding section in sequence, and the first welding section, the second welding section and the third welding section are respectively welded to the side of the bracket main box 3, the lower surface of the cover plate 2 and the inner surface of the bending portion 201; preferably, the cross-section of the three-dimensional reinforcing rib 4 is trapezoidal; illustratively, the three-dimensional reinforcing rib 4 is obtained by bending the two ends of a flat plate inward to obtain a U-shaped structure, and the outer peripheral edge of the three-dimensional reinforcing rib 4 forms a first welding section, a second welding section and a third welding section, which are matched with the side of the bracket main box 3, the lower surface of the cover plate 2 and the surface of the bending portion 201, and are welded; the three-dimensional reinforcing rib 4 further connects the bracket main box 3 and the cover plate 2 into a whole, which can not only play a local reinforcement role of an ordinary rib plate, but also because it has solid support in three directions of the rib plate, and the overall structure is a trapezoidal box structure, the rigidity and support area are stronger, and its support capacity is far better than that of an ordinary rib plate.

[0034] In another embodiment, an end plate 5 is further included, which is welded to the end edges of the bracket main box 3 and the cover plate 2, and closes the space enclosed by the bracket main box 3 and the cover plate 2; the existence of the end plate 5 further encloses the main box 3 and the cover plate 2 into a closed space, thereby improving the overall supporting strength of the battery pack support.

[0035] In another embodiment, a mud guard bracket and a wiring harness bracket are further provided on the cover plate 2; exemplarily, the wiring harness bracket is designed as an L-shaped bent plate structure, and the bent edge occupies a very small part of the wire hole space, so that the bent edge is against the wire harness away from the sharp edge of the wire hole, thereby better protecting the wire harness; exemplarily, the battery pack support is integrated with exhaust brackets, mud guard brackets, pipeline brackets, etc., which are used for exhaust pipelines, mud guards, etc., so that the battery pack mounting seat is multifunctionally integrated, reducing other brackets on the frame, simplifying the design, and reducing the weight of the entire vehicle.

[0036] An embodiment of the present application also provides an off-road mining dump truck frame, including an off-road mining dump truck battery pack support, the frame having a longitudinal beam 1, and the battery pack support in the above embodiment is connected to the longitudinal beam 1 through a mounting plate 301; compared with the equal-section design in the prior art and the battery pack support being connected to both sides of the longitudinal beam 1, this embodiment can significantly save left and right space, occupy less space, and have a high space utilization rate, forming an overall box-type structure with high support strength, a hollow interior, and a variable cross-section design, and a significant weight reduction effect.

[0037] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
