Description

Technical Field

[0001] This utility model relates to the field of electric heavy-duty truck technology, specifically to an integrated mounting bracket under the cab of an electric heavy-duty truck. Background Technology

[0002] In the overall layout design of electric heavy trucks, the multi-function controller, electric power steering pump, electric air conditioning compressor, electric air pump, electronic water pump, battery, etc. are usually distributed on both sides of the chassis frame.

[0003] Currently, electric heavy-duty trucks rely on electric power, and their core components and circuits are highly sensitive to water. All electric heavy-duty truck operating sites currently require high-pressure water jet washing of the vehicles. Under the all-around washing of the high-pressure water jets, the core components and circuit connectors located on both sides of the frame are extremely susceptible to water ingress, leading to short circuits or leakage, and malfunctioning. The distributed layout of core components requires the design of individual mounting brackets for each component, resulting in a wide variety of bracket types and hindering overall vehicle weight reduction. When the main assemblies (model or layout) or overall vehicle dimensions (length, wheelbase) change, the original layout and mounting brackets may no longer be suitable, requiring redesign and rearrangement of the brackets. This results in poor component interchangeability. To achieve overall vehicle weight reduction and improve passability, the overall length and wheelbase of electric heavy-duty trucks are constantly being shortened, continuously compressing the space available for core components. Electric heavy-duty truck power batteries are available in rear-mounted and side-mounted types. When the side-mounted type is used, the power battery occupies almost both sides of the vehicle frame, leaving almost no space for core components. This makes the arrangement difficult. The distributed arrangement of core components results in a slower production cycle and higher labor intensity for workers during the final assembly line, which is not conducive to improving the overall vehicle production efficiency.

[0004] An integrated mounting bracket under the cab of an electric heavy-duty truck is proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated mounting bracket under the cab of an electric heavy-duty truck to solve the problem mentioned in the background art that the current distribution of core components results in a slow production cycle and high labor intensity for workers during final assembly line production, which is not conducive to improving the overall vehicle production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated mounting bracket under the cab of an electric heavy truck, comprising two frames;

[0007] Also includes:

[0008] U-shaped plates are symmetrically installed on the lower inner side of the two frames, and several mounting holes are opened through the top of each U-shaped plate. Brackets are symmetrically installed on the top of each frame, and waist-shaped holes are symmetrically opened through the bottom of each bracket. Bracket bodies are symmetrically installed on the top of each bracket by bolts, and a mounting bracket is fixedly installed on one side between the two bracket bodies.

[0009] Among them, mounting plates are symmetrically installed on the other side between the two bracket bodies, and several positioning seats are fixedly installed on the top of the two mounting plates. Connecting holes are symmetrically opened on one side of the two positioning seats that are far apart, and J-shaped rods are provided inside the connecting holes.

[0010] Two sets of limiting frames are respectively provided on the upper outer side of the two sets of J-shaped rods, and positioning bolts are threadedly connected to the upper outer side of the two sets of J-shaped rods. A support frame is fixedly installed on one side of the top of the two bracket bodies, and a fixing frame is fixedly installed on one side of the top of the support frame. A wire harness is fixedly installed on the other side of the top of the support frame, and a fixing component is provided on one side of the wire harness. Several wire harness holes are opened through one side of the wire harness.

[0011] Preferably, the fixing assembly includes fixing rods symmetrically installed inside the cable tie frame, and movable plates are slidably connected to the outside of the two fixing rods. Positioning plates are fixedly installed on one side of each of the several cable tie holes.

[0012] Preferably, fixing blocks are symmetrically installed on the upper inner side of the cable tie frame, and positioning frames are fixedly installed on the top of each of the two fixing blocks. A bidirectional lead screw is rotatably connected between the two positioning frames, and one end of the bidirectional lead screw passes through one side of the positioning frame and is fixedly installed with a turntable.

[0013] Preferably, a rotating rod is rotatably connected to one side of the turntable, and a limiting rod is slidably connected inside the rotating rod. Furthermore, a plurality of limiting grooves are provided on one side of the positioning frame, and the limiting rods are engaged with the limiting grooves.

[0014] Preferably, a telescopic spring is sleeved on the outer side of the limiting rod, one end of the telescopic spring is fixedly connected to the rotating rod, and the other end of the telescopic spring is fixedly installed with an mounting block, which is also fixedly connected to the limiting rod.

[0015] Preferably, a connecting rod is hinged to the top of the mounting block, and a push plate is hinged to the end of the connecting rod away from the mounting block. A guide rod is slidably connected to the inner side of the push plate, and the guide rod is fixedly connected to the rotating rod.

[0016] Preferably, both U-shaped plates are bent steel plates.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: This integrated mounting bracket under the cab of an electric heavy-duty truck has excellent waterproof performance for high and low pressure system components, effectively preventing water ingress into these components caused by high-pressure water jets washing the vehicle. Its compact design saves space, is structurally stable, and has good versatility, effectively reducing the overall vehicle weight. The highly integrated design facilitates convenient and quick subsequent inspection, maintenance, and assembly, enabling modular assembly of components. Some components can be installed on the integrated bracket offline before being hoisted onto the vehicle for assembly, reducing the labor intensity of operators and improving production efficiency. The specific details are as follows:

[0018] 1. Two U-shaped plates can integrate the installation of electric air conditioning compressor, electric power steering pump, air pump, air filter, and air filter muffler. The integrated design effectively utilizes the mounting space under the vehicle frame. The integrated installation of the air filter, muffler, and electric air pump requires shorter piping. The two U-shaped plates together form a water-blocking structure, effectively preventing high-pressure water and mud from washing upwards from the bottom of the vehicle. The U-shaped plates have a simple and high-strength structure, consisting entirely of bent and punched parts, making them very easy to manufacture. Multiple sets of mounting holes are provided to accommodate different types of components, and the arrangement and orientation can be adjusted appropriately, offering strong versatility. Two sets of brackets are also included. The components fixed to the bracket body can be raised to avoid interference with the electric air pump fixed below. Depending on the different lower body heights, the brackets can be replaced individually without replacing the entire bracket. The two sets of brackets are drilled to reduce the counterweight and improve the vehicle's lightweight design. When installing the battery, the position of the J-shaped rod can be adjusted according to the size of the battery, so that the J-shaped rod connects to the connection holes in different positions. Then, the battery can be fixed by two limit brackets and positioning bolts, making it suitable for installing batteries of different specifications. It has good versatility and the mounting bracket facilitates the installation of other components.

[0019] 2. A fixing component is installed on one side of the cable tie frame. The wiring of the entire component can pass through the cable tie holes of the cable tie frame. Then, by holding the rotating rod and the push plate, the push plate can be moved towards the rotating rod. This, in turn, pushes the limiting rod through the connecting rod, stretching the telescopic spring and disengaging the limiting rod from the limiting groove. Then, by holding the rotating rod and the push plate, the turntable can be rotated, causing the bidirectional screw to rotate. This causes the two movable plates to move closer together. The positioning plates on the movable plates can fix the cable tie. Afterward, the limiting rod can be aligned with the adjacent limiting groove. The push plate can be released, and under the action of the telescopic spring, the limiting rod returns to its original position and engages with the other limiting groove, thus locking the turntable and preventing accidental rotation of the turntable and the bidirectional screw. The fixing component can prevent the cable tie from becoming tangled and also prevent the cable tie from falling off, facilitating subsequent maintenance and improving practicality.

The integrated design effectively utilizes the mounting space at the bottom of the vehicle frame 1. The integrated installation of the air filter, muffler, and electric air pump requires shorter piping. The two U-shaped plates 101 together form a water-blocking structure, effectively preventing high-pressure water and mud from washing upwards from the bottom of the vehicle. The U-shaped plates 101 have a simple structure and high strength, consisting entirely of bent and punched parts, making them very easy to manufacture.

This allows the limiting rod 209 to move through the connecting rod 214, which can stretch the telescopic spring 211 and disengage the limiting rod 209 from the limiting groove 210. Then, the rotating rod 208 and the push plate 213 can be held to rotate the turntable 207, which causes the bidirectional lead screw 206 to rotate, allowing... The two movable plates 202 are brought closer together, and the wire harness can be fixed by the positioning plate 203 on the movable plate 202. Then, the limiting rod 209 can be aligned with the adjacent limiting groove 210.
