Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically, it is an integrated bracket for an electric commercial vehicle controller. Background Technology

[0002] In the field of new energy vehicles, electric commercial vehicles occupy an important position. As electric commercial vehicle technology continues to evolve, the types and number of controllers installed within them are constantly increasing, such as motor controllers, battery management system controllers, and BCM controllers. However, current installation methods often disperse these controllers across different areas of the vehicle, leading to a series of pressing problems: complex wiring systems and redundant wire lengths not only occupy significant interior space but also cause extreme inconvenience during vehicle assembly and subsequent maintenance, severely hindering production and maintenance efficiency. Therefore, developing a specialized bracket device for integrating multiple controllers is of paramount practical significance for optimizing the overall internal layout of electric commercial vehicles and improving their overall performance.

[0003] Meanwhile, traditional brackets have relatively low shock absorption efficiency and cannot effectively isolate vibrations generated during driving, which can adversely affect the lifespan of various controllers during vehicle operation. In addition, some brackets involve cumbersome installation and removal of controllers, requiring significant manpower and time costs, and severely reducing vehicle maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated bracket for electric commercial vehicle controllers, which solves the technical problems of scattered controller installation and poor shock absorption effect of traditional brackets for installing controllers in the prior art.

[0005] The present invention solves the above problems through the following technical solution:

[0006] An integrated bracket for electric commercial vehicle controllers, mounted on a left and right longitudinal beam, includes: a first mounting bracket assembly, a second mounting bracket assembly, and a third mounting bracket assembly connected sequentially from bottom to top.

Each frame of the first, second, and third mounting bracket assemblies has several mounting holes for mounting the controllers. The integrated bracket connects to the left and right longitudinal beams from the bottom side of the second mounting space via connecting components, so that the first mounting space is located within the left and right longitudinal beams. Rubber shock-absorbing pads are placed between the connecting components and the frame of the second mounting space to absorb and attenuate vibrations and impacts.

[0007] As a further improvement, the controller includes at least a high-voltage box, a multi-function controller, and a BCM controller, wherein the high-voltage box is installed in a first installation space, the multi-function controller is installed in a second installation space, and the BCM controller is installed in a third installation space.

[0010] As a further improvement, two second horizontal frames are vertically connected to the upper ends of four first vertical frames, and the two second horizontal frames are parallel to each other; two second horizontal frames are vertically connected to two second vertical frames, and the two second vertical frames are parallel to each other; two parallel portal frames are vertically arranged above the two second vertical frames to form a cubic second installation space.

[0011] As a further improvement, two parallel third longitudinal frames are vertically connected above the two portal frames to form a third mounting space with bottom mounting.

[0012] As a further improvement, the integrated bracket also forms a fourth mounting space for installing a battery; the two portal frames are located inside the two second horizontal frames and are offset from the right or left side, so that a battery mounting bracket connecting the two second vertical frames is provided above the second horizontal frame offset from one side, so that the fourth mounting space is formed by the battery mounting bracket and the adjacent portal frame; and / or a relay connecting piece is also provided on the second vertical frame to connect and install a relay.

[0013] As a further improvement, the first vertical frame located on the front side is raised, that is, the first vertical frame on the front side is higher than the first vertical frame on the rear side, so that the second horizontal frame located on the rear side is lower than the second horizontal frame located on the front side, so that the cooling system pipeline can pass through the front side of the raised space; the second vertical frame is connected above the second horizontal frame located on the rear side by a support column, so that the second horizontal frame on the front side and the second horizontal frame on the rear side are at the same height.

[0014] As a further improvement, the second horizontal frame and the second vertical frame located at the rear are respectively connected to "L"-shaped first connectors, and the second vertical frame is connected to the first connectors through "Z"-shaped second connectors, so as to connect the left and right longitudinal beams through the first connectors, and erect the entire integrated support on the left and right longitudinal beams.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Combined with appendix Figure 1-2 As shown, an integrated bracket for an electric commercial vehicle controller is mounted on a left longitudinal beam 9 and a right longitudinal beam 10. It includes at least several mounting bracket assemblies, such as a first mounting bracket assembly 1, a second mounting bracket assembly 2, and a third mounting bracket assembly 3, for mounting controllers such as a high-voltage box 6, a multi-function controller 8, and a BCM controller 7. Several controller connecting pieces are provided inwardly on the bottom side of the second mounting space for positioning and mounting the controllers.

[0027] Each of the first, second, and third mounting bracket assemblies has several mounting holes for mounting the controller. The integrated bracket is connected to the left and right longitudinal beams via connecting components from the bottom of the second mounting space, so that the first mounting space is located within the left longitudinal beam 9 and right longitudinal beam 10. Rubber shock-absorbing pads are provided between the connecting components and the frame at the bottom of the second mounting space to absorb and attenuate the generated vibrations and impacts.

[0028] In this embodiment, the integrated bracket for an electric commercial vehicle controller includes: a first mounting bracket assembly consisting of two first vertical frames 11, two first horizontal frames 12, and four first vertical frames 13; a second mounting bracket assembly consisting of two second vertical frames 21, two second horizontal frames 22, and two portal frames 23; a third mounting bracket assembly consisting of the upper parts of the two portal frames 23 and the two third vertical frames 31; a high-voltage box is disposed within a first mounting space enclosed by the first mounting bracket assembly; a multi-function controller is disposed within a second mounting space enclosed by the second mounting bracket assembly; and a BCM controller is disposed above the third mounting bracket assembly.

[0029] Specifically, two first horizontal frames 12 are perpendicularly connected to two first vertical frames 11, and the two first horizontal frames 12 are arranged parallel to each other between the two first vertical frames 11; four first vertical frames 13 are perpendicularly arranged at the ends of the two first vertical frames 11, and the four first vertical frames 13 are arranged parallel to each other above the two first vertical frames 11 to form a cubic first installation space. Two second horizontal frames 22 are perpendicularly connected to the upper ends of the four first vertical frames 13, and the two second horizontal frames 22 are parallel to each other; two second vertical frames 21 are perpendicularly connected to the two second horizontal frames 22, and the two second vertical frames 21 are parallel to each other; two parallel portal frames 23 are perpendicularly arranged above the two second vertical frames 21 to form a cubic second installation space. Two parallel third vertical frames 31 are perpendicularly connected above the two portal frames 23 to form a third installation space with a bottom mounting surface.

[0030] Furthermore, each of the first, second, and third mounting bracket assemblies is provided with several mounting holes that cooperate with each controller for installation, so that each controller can be installed in a suitable position by means of bolts, screws, or other fixing components.

[0031] Preferably, the two portal frames 23 are located inside the two second horizontal frames 22 and are offset from the right or left side, so that a battery mounting bracket 24 connecting the two second vertical frames 21 is provided above the second horizontal frame 22 offset from one side, so that a fourth installation space is formed by the battery mounting bracket 24 and the adjacent portal frame 23, for installing a number of batteries, and the open structure facilitates the replacement of batteries.

[0032] Since only a fuse is installed on the rear left side of the high-pressure box, and a wiring harness needs to be connected to the front left side, which would interfere with the cooling system piping, the first vertical frame 13 on the front side is raised so that it is higher than the first vertical frame 13 on the rear side. The second horizontal frame 22 on the rear side is lower than the second horizontal frame 22 on the front side. The second vertical frame 21 is connected to the second horizontal frame 22 on the rear side via a support column 25, allowing the cooling system piping to pass through the raised space. The second vertical frame 21 is connected to the second horizontal frame 22 on the rear side via a support column 25, ensuring that the second horizontal frames 22 on the front and rear sides are at the same height.

[0033] The second horizontal frame 22 located at the rear is connected to an "L"-shaped first connector 4 by bolts, screws or other connecting parts, so that the left longitudinal beam and the right longitudinal beam are connected through the other end of the "L"-shaped first connector 4; the outer side of the second longitudinal frame 21 is provided with a "Z"-shaped second connector 5, which is connected to the "L"-shaped first connector 4, so that the left longitudinal beam and the right longitudinal beam are connected through the other end of the "L"-shaped first connector 4, so that the entire integrated bracket is erected on the left longitudinal beam and the right longitudinal beam, and the first installation space is located inside the left longitudinal beam and the right longitudinal beam.

[0034] Preferably, a rubber damping pad 28 is provided in the connecting component between the integrated bracket and the vehicle mounting area, i.e., the left and right longitudinal beams. The rubber damping pad 28 is tightly connected to the integrated bracket and the vehicle frame, i.e., the left and right longitudinal beams, through the connecting component, forming a stable buffer connection system. During vehicle operation, the rubber damping pad 28 can effectively absorb and attenuate various vibrations and impacts generated by road bumps, vehicle acceleration and deceleration, etc., providing a relatively stable, low-vibration working environment for the controller. This avoids problems such as loosening, poor contact, or damage to the precision electronic components inside the controller due to long-term vibration, ensuring the normal operation of the controller and the stability of signal transmission.

[0035] In an optional embodiment, a plurality of controller connecting pieces 26 are provided inward on the second longitudinal frame 21 at the bottom of the first mounting space. The multi-function controller is installed through the plurality of controller connecting pieces 26, and the controller connecting pieces 26 are provided with at least one through hole to adapt to multiple models of multi-function controllers through at least one through hole.

[0036] Preferably, in this embodiment, the first mounting bracket assembly and the second mounting bracket assembly, except for the portal frame 23, are both made of metal rectangular tubes, and the metal rectangular tubes are connected by welding. The second longitudinal frame 21 is also provided with a relay connecting piece 27 for connecting and installing relays.

[0037] The integrated bracket of this utility model is made of aluminum alloy and other metal materials, and is precision-machined into a plate structure. Its surface has multiple precisely designed mounting holes evenly distributed to mate with various controllers. The size and position of these mounting holes perfectly match the mounting interfaces of various controllers, providing a stable and reliable mounting foundation for the controllers and ensuring that the controllers will not shift or loosen due to vibrations or other factors during vehicle operation. The third mounting bracket assembly is made of plate metal and is connected by screws.

[0038] Furthermore, the integrated bracket adopts an open-air design, allowing the controller to fully contact the outside air after installation, maximizing the heat dissipation area. Simultaneously, a cleverly designed perforated structure is incorporated at the bottom of the battery mounting bracket. This perforated design not only achieves lightweighting of the integrated bracket without compromising its overall structural strength and basic functionality, reducing the overall load on the vehicle and helping to lower energy consumption and increase driving range, but also effectively improves airflow around the controller, creating a good heat dissipation channel. This accelerates heat dissipation, enabling the controller to operate continuously and efficiently in a suitable temperature environment, effectively extending its lifespan and reducing the probability of malfunctions due to overheating.

[0039] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
