Description

Technical Field

[0001] This utility model relates to the technical field of new energy vehicle components, and in particular, to an integrated mounting bracket for dual water tanks on a new energy mixer truck. Background Technology

[0002] As thermal management technology in new energy vehicles evolves towards integration, the thermal management system must simultaneously meet the collaborative operation requirements of multiple circuits, including the battery coolant reservoir, motor cooling circuit, and cabin air conditioning. Current thermal management systems have evolved from independent modules into comprehensive engineering projects encompassing subsystems such as the battery, motor, and air conditioning, placing higher demands on the compactness of component layout. Compared to traditional vehicles, new energy hybrid electric vehicles, in addition to the traditional engine / transmission powertrain, also include a motor-driven coolant reservoir and a battery system coolant reservoir.

[0003] Existing new energy vehicles have a compact layout, and traditional single-cabinet independent brackets occupy a large space, making it difficult to meet the installation needs of multiple water tanks. Moreover, the installation of split brackets is cumbersome, requiring disassembly of each one for maintenance, which is inefficient. Existing water tank brackets use a single snap-fit ​​structure, lacking adjustment capabilities and unable to accommodate water tanks of different sizes (such as round battery coolant tanks and square cooling unit tanks). At the same time, the design of water tank brackets is complex, requiring multiple processes such as bending and welding, and the designed installation size is large, which is not conducive to installation in the limited space of existing integrated systems.

[0004] Existing patent publication number CN208263963U discloses a mounting bracket for an expansion tank. The mounting bracket for an expansion tank includes a plate-shaped body for supporting the expansion tank. The body has: a first slot and a second slot for mounting the expansion tank; welding points for connecting the mounting bracket to the wheel arch sheet metal of the vehicle body; and weight-reducing holes for reducing the weight of the mounting bracket. This utility model's mounting bracket for an expansion tank improves the installation flexibility of the expansion tank and saves installation space. However, the shape and size of expansion tanks may vary significantly between different vehicle models. Adjusting the existing slots alone may not be suitable for all models. For expansion tanks with special shapes, a more complex slot structure may be required. The existing design has certain limitations and a limited range of applicability. Furthermore, the mounting bracket is fixed to the wheel arch sheet metal by welding points. Welding is a permanent connection. If the position needs to be adjusted after installation, modification is difficult and may damage the bracket or sheet metal, affecting production efficiency and hindering later repair and replacement. Replacement requires removing the welding points, increasing repair costs and difficulty. Utility Model Content

[0005] This utility model addresses the problems of existing single-cabin independent brackets occupying a large space, making it difficult to meet the installation needs of multiple water tanks, and the cumbersome installation of separate brackets, requiring individual disassembly for maintenance, resulting in low efficiency. Existing water tank brackets use a single snap-fit ​​structure, lacking adjustment capabilities and unable to accommodate water tanks of different sizes (such as round battery cooling water tanks and square cooling unit water tanks); at the same time, the design of the water tank brackets is complex, requiring multiple processes such as bending and welding, and the design and installation dimensions are large, which is not conducive to the installation of existing integrated systems in limited space. Therefore, this invention proposes an integrated mounting bracket for dual water tanks in new energy mixer trucks.

[0006] A dual-cooling-reservoir integrated mounting bracket for a new energy mixer truck includes a bracket body with a double U-shaped structure, and a bracket body for simultaneously fixing the battery system cooling water reservoir and the drive system cooling water reservoir. The bracket body is integrally formed by laser cutting. The bracket body is installed on one end of the vehicle's integrated battery frame assembly through a connecting device. The bracket body is provided with water reservoir mounting holes for adjusting the installation position of the water reservoirs.

[0007] Furthermore, the bracket body is composed of a bracket mounting part and multiple kettle mounting arms, and two adjacent kettle mounting arms and the mounting part form a first kettle mounting groove, a water pipe through groove and a second kettle mounting groove, and the kettle mounting hole is located at the end of the kettle mounting arm.

[0008] Furthermore, the bracket mounting portion is provided with at least four bolt mounting holes.

[0009] Furthermore, the inner wall of the kettle mounting arm is provided with a limiting protrusion that matches the outer contour of the kettle.

[0010] Furthermore, the thickness of the support body is 2-5mm, the material is high-strength aluminum alloy, and the surface is provided with an anti-corrosion coating.

[0011] Furthermore, the kettle mounting hole is an oblong kettle mounting hole, and the axis of the hole is consistent with the length direction of the mounting arm, so that the position of the kettle can be adjusted up and down and back and forth along the bracket body to adapt to the installation requirements of kettles of different sizes.

[0012] Furthermore, the mounting surface of the bracket body and the battery integrated frame assembly is provided with a shock-absorbing pad, which is fixedly connected to the bracket body by bolts.

[0013] Furthermore, the bracket body can be extended to connect to a modular bracket unit, which is spliced ​​with the double U-shaped bracket body through a slot to add a third kettle mounting position.

[0014] Furthermore, the bracket body is fixedly mounted on the vehicle integrated battery frame assembly by bolts.

[0015] Furthermore, the bracket body is embedded with a coolant circulation pipeline, which is linked to the vehicle's thermal management system to actively control the reservoir temperature.

[0029] Example 1

[0030] like Figure 1As shown in the figure, a double-water-kettle integrated mounting bracket for a new energy mixer truck includes a bracket body 1 with a double-U structure, which is used to fix the battery system cooling water kettle and the drive system cooling water kettle simultaneously. The bracket body 1 is integrally formed by laser cutting; the bracket body 1 is installed at one end of the vehicle integrated battery frame assembly 9 through a connecting device, and the bracket body 1 is provided with water kettle mounting holes 2 for adjusting the mounting position of the water kettle.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the double-U-shaped bracket body 1 is laser cut from 3mm-thick 6061 high-strength aluminum alloy, and the overall structure is in the shape of a Chinese character 'Ri'. The bracket body 1 is composed of a middle rectangular mounting part 6 and water kettle mounting arms 3 on one side of the mounting part 6. Two adjacent water kettle mounting arms 3 and the mounting part 6 form a first water kettle mounting groove 4, a water pipe routing groove 5, and a second water kettle mounting groove 8. The water kettle mounting holes 2 are arranged at the ends of the water kettle mounting arms 3. The water pipe routing groove 5 is located between the first water kettle mounting groove 4 and the second water kettle mounting groove 8, and is used to guide the inlet and outlet water pipes of the two water kettles to be arranged separately. The first water kettle mounting groove 4 and the second water kettle mounting groove 8 are adapted to a circular battery coolant kettle (inner diameter 120mm) and a square drive system coolant kettle (side length 100mm×80mm).

[0032] In this embodiment, the bracket body 1 includes four water kettle mounting arms 3. The inner side walls of the water kettle mounting arms 3 (the side facing the water kettle groove) are provided with limit protrusions matching the outer contour of the water kettle. Specifically, a semi-circular arc limit protrusion is arranged in the first water kettle mounting groove 4, and the radius of the semi-circular arc limit protrusion is 3mm. A right-angle limit protrusion is arranged in the second water kettle mounting groove 8, and the side length of the right-angle limit protrusion is 5mm. They are closely fitted with the flange of the outer contour of the water kettle respectively to ensure the firm installation of the water kettle. The ends of the water kettle mounting arms 3 are provided with waist-shaped water kettle mounting holes 2 (length 25mm×width 6mm), and the axis of the holes is consistent with the length direction of the water kettle mounting arms 3, so that the position of the water kettle can be adjusted in the up-down and front-back directions along the bracket body 1 to adapt to the installation requirements of different specifications of water kettles.

[0033] As Figure 3 shown, the mounting part of the bottom of the bracket body 1 connected to the vehicle integrated battery frame assembly 9 is provided with two groups of long strip-shaped waist-shaped holes (length 40mm×width 10mm), which support the fine adjustment of the bracket body 1 in the horizontal (±20mm) and longitudinal (±15mm) directions of the vehicle battery frame assembly 9. Anti-loosening bolts are installed in the waist-shaped holes. The bracket body 1 is fixedly installed on the top of the vehicle integrated battery frame assembly 9 through two groups of M8 bolts.

[0034] The bracket body 1 of this embodiment is applicable to new energy mixer trucks with a wheelbase of more than 3.5 meters. The circular kettle (volume 5L) and the square kettle (volume 3L) are installed side by side, and the water pipes are introduced into the pipeline system at the bottom of the vehicle frame through the water pipe routing groove 5.

[0035] Example 2

[0036] like Figure 1 As shown, a dual-cooling-reservoir integrated mounting bracket for a new energy mixer truck includes a bracket body 1 with a double U-shaped structure, used to simultaneously fix the battery system cooling water reservoir and the drive system cooling water reservoir. The bracket body 1 is integrally formed by laser cutting. The bracket body 1 is installed at one end of the vehicle integrated battery frame assembly 9 through a connecting device. The bracket body 1 is provided with a water reservoir mounting hole 2 for adjusting the water reservoir mounting position.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the bracket body 1 is made of 4mm thick 6061-T6 high-strength aluminum alloy, which is integrally formed by laser cutting, and the surface is sprayed with an 80μm thick epoxy resin anti-corrosion coating to prevent the bracket body from being corroded and damaged by coolant.

[0038] like Figure 3 and Figure 4 As shown, a 5mm thick neoprene rubber shock-absorbing pad is attached to the contact surface between the mounting part 6 and the integrated battery frame assembly 9 of the electric vehicle. The shock-absorbing pad has countersunk holes corresponding to the bolt mounting holes 7, and is fixed by M10 bolts and spring washers, making the bracket body 1 more securely installed. A silicone buffer strip is embedded in the contact part between the water bottle mounting arm 3 and the water bottle. The buffer strip is continuously distributed along the inner wall of the U-shaped groove and is fixed by adhesive backing.

[0039] The kettle mounting hole 2 is a combination of a circular through hole and a sliding groove. The groove is 8mm wide and supports the kettle to be adjusted by ±5mm in the left and right directions (to accommodate bracket installation errors).

[0040] Example 3

[0041] like Figure 1 As shown, a dual-cooling-reservoir integrated mounting bracket for a new energy mixer truck includes a bracket body 1 with a double U-shaped structure, used to simultaneously fix the battery system cooling water reservoir and the drive system cooling water reservoir. The bracket body 1 is integrally formed by laser cutting. The bracket body 1 is installed at one end of the vehicle integrated battery frame assembly 9 through a connecting device. The bracket body 1 is provided with a water reservoir mounting hole 2 for adjusting the water reservoir mounting position.

[0042] In this embodiment, a transverse slot is provided on the outer side of the kettle mounting arm 3 on one side of the bracket body 1, which can be used to splice L-shaped modular bracket units (150mm long × 80mm wide). The modular bracket units are connected to the main bracket body 1 slot via bottom sliders and then fixed by two M5 bolts. The modular unit has a third kettle mounting slot (80mm in diameter, suitable for air conditioning system coolant reservoirs), which increases the overall length after expansion, bringing the total number of mounting positions to three. Both the bracket body 1 and the modular units are laser-cut, and sealing strips are provided at the modular interfaces to prevent liquid leakage.

[0043] Specifically, an 8mm aluminum alloy coolant circulation pipe is embedded inside the mounting part of the bracket body 1. The pipe is led out from the main coolant branch of the battery frame assembly 9 and contacts the bracket through a finned heat exchanger to achieve temperature control of the reservoir. An electronic temperature control valve (accuracy ±2℃) is installed on the pipe, which is linked with the vehicle thermal management system. When the reservoir temperature exceeds the threshold, the circulation is automatically activated for heat dissipation.

[0044] In this embodiment, the bracket is suitable for high-end new energy mixer trucks equipped with a three-circuit cooling system. It can simultaneously integrate the battery, drive motor, and air conditioning system coolant reservoir, and control the reservoir temperature within a certain range through thermal management linkage to ensure the stability of the new energy vehicle system.

[0045] Obviously, the above-described embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
