Description

Technical Field

[0001] This utility model relates to the field of power cabinet technology, and in particular to a lightweight aluminum alloy vehicle power cabinet. Background Technology

[0002] A vehicle power cabinet is an integrated power management device installed on buses, trucks, engineering vehicles, RVs, and special-purpose vehicles. It is usually made of lightweight aluminum alloy to reduce vehicle weight and improve fuel efficiency or range. Its core function is to centrally manage the vehicle's power supply, distribution, conversion, and protection, ensuring the stable operation of various electrical equipment on the vehicle, such as air conditioning, lighting, communication equipment, tools, and instruments.

[0003] The power cabinet is fixed to an aluminum alloy frame with screws. Power from the vehicle's main power source, such as the onboard generator, battery pack, and external AC power, is distributed to different electrical devices. Internal switches and fuses control the on / off state of each circuit. Some high-end models can achieve intelligent distribution, automatically adjusting power supply based on device priority to avoid overload. The layout of electrical equipment in vehicles often changes depending on the scenario. For example, a motorhome might add a refrigerator or projector, requiring the power cabinet to be moved longitudinally closer to the equipment to shorten cable length, reduce power loss, and avoid messy cable laying across areas, reducing the risk of tripping and wear. Similarly, if a construction vehicle temporarily adds surveying instruments or lighting equipment, a longitudinally movable onboard power cabinet is needed to bring it closer to the concentrated equipment area, simplifying wiring logic. However, screw-fixed onboard power cabinets are inconvenient to adjust and lack flexibility. Therefore, those skilled in the art have provided a lightweight aluminum alloy onboard power cabinet to solve the problems mentioned in the background. Utility Model Content

[0004] 1. Technical Solution

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a lightweight aluminum alloy vehicle power cabinet, comprising,

[0007] Aluminum alloy frame, including frame body and vehicle power cabinet located inside the frame body;

[0008] The fixed structure includes a box located at the lower end of the vehicle power cabinet, a mounting shaft rotatably installed inside the box, a worm gear and a gear sleeved on the outer wall of the mounting shaft, an upper gear plate and a lower gear plate located at the upper and lower ends of the box and meshing with the gear, an insert plate provided at one end of the upper gear plate and the lower gear plate, a rotating shaft that rotates through the box, a worm gear sleeved on the outer wall of the rotating shaft and meshing with the worm gear, and an insert block located at one end of the insert plate.

[0009] as well as;

[0010] The adjustment structure includes guide plates fixed to the inner walls on both sides of the frame and slots evenly distributed on the inner walls of the guide plates.

[0011] Furthermore, the inside of both ends and the bottom of the vehicle power cabinet are provided with equally spaced slots, and the rear end of the vehicle power cabinet is provided with a support plate with mounting holes inside.

[0012] Specifically, the slots are used for the passage of wires between electrical equipment, the support plates are used for the installation of electrical equipment, and the mounting holes are used for the installation of parts.

[0013] Furthermore, one end of the rotating shaft is provided with a torsion block with anti-slip texture on the outer wall, and both ends of the housing are provided with stroke openings, and the insert plate is slidably installed inside the stroke openings;

[0014] Specifically, the gripping torsion block drives the rotating shaft to rotate, and the anti-slip texture improves the gripping anti-slip performance, while the stroke port ensures that the insert plate can effectively enter and exit the box.

[0015] Furthermore, the upper toothed plate and the lower toothed plate are provided with guide rails at opposite ends, and the inner walls of the upper and lower ends of the box are provided with rotating seats. Each of the rotating seats is rotatably mounted with a ball bearing that is rolled on the inner wall of the guide rail at opposite ends.

[0016] Specifically, the rotating seat rolls inside the guide rail via ball bearings, which slides and guides the laterally moving upper and lower toothed plates, and the rolling contact reduces movement wear and resistance.

[0017] Furthermore, both ends of the vehicle power cabinet are provided with sliders that are slidably sleeved on the outer wall of the guide plate. The inner wall of the slider is provided with a rotating seat II. The rotating seat II is rotatably installed with a ball II. The front and rear ends of the guide plate are provided with rolling grooves, and the ball II is rotatably installed inside the rolling grooves.

[0018] Specifically, the slider slides on the outer wall of the guide plate, and the rotating seat 2 rolls inside the groove through the ball bearing 2 to provide sliding support for the power cabinet on the vehicle.

[0019] Furthermore, mounting grooves are provided at both the front and rear ends of the slider, one end of the rotating seat is located inside the mounting groove, and a spring connected to one end of the rotating seat is provided on the inner wall of the mounting groove.

[0020] Specifically, the spring provides elastic support to one end of the rotating seat, so that the ball is resisted when it slides, thus preventing the power cabinet on the vehicle from slipping down suddenly and causing a safety hazard when it comes off the fixed position.

[0021] 2. Beneficial effects

[0022] Compared with existing technologies, the advantages of this utility model are:

[0023] This utility model utilizes a rotating torsion block to drive a rotating shaft to rotate a worm gear. The worm gear drives a worm wheel and gears to rotate. The gears mesh with upper and lower toothed plates, causing them to slide in opposite directions. This drives the insertion plate and insertion block to extend and retract along the travel opening of the housing, locking or separating from the guide plate slot. Simultaneously, a slider engages with the guide plate, and two balls roll in the groove. With the guidance of the guide rail and the first ball, the power cabinet can move smoothly longitudinally. The position of the power cabinet can be quickly adjusted without tools, improving efficiency. It is suitable for the layout changes of vehicle power cabinets with aluminum alloy frame support structures. The multi-structure linkage reduces friction and resistance, making adjustment effortless and without jamming. The elastic buffer and multi-point locking design improve stability in bumpy environments.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] Please see Figure 1-5 As shown, this embodiment is a lightweight aluminum alloy vehicle power cabinet, including,

[0041] The aluminum alloy frame 100 includes a frame body 101 and an on-board power cabinet 102 located inside the frame body 101.

[0042] The fixed structure 200 includes a box 203 located at the lower end of the vehicle power cabinet 102, a mounting shaft 208 rotatably installed inside the box 203, a worm gear 213 and a gear 214 sleeved on the outer wall of the mounting shaft 208, an upper toothed plate 210 and a lower toothed plate 209 located at the upper and lower ends of the box 203 and meshing with the gear 214, an insert plate 201 provided at one end of the upper toothed plate 210 and the lower toothed plate 209, a rotating shaft 211 rotatably penetrating the box 203, a worm 212 sleeved on the outer wall of the rotating shaft 211 and meshing with the worm gear 213, and an insert block 202 located at one end of the insert plate 201.

[0043] The vehicle power cabinet 102 has equally spaced slots 103 inside both ends and the bottom, and a support plate 104 with mounting holes inside is provided inside the rear end of the vehicle power cabinet 102.

[0044] One end of the rotating shaft 211 is provided with a twist block 215 with anti-slip texture on the outer wall, and both ends of the housing 203 are provided with stroke ports 204, and the insert plate 201 is slidably installed inside the stroke ports 204.

[0045] The upper toothed plate 210 and the lower toothed plate 209 are both provided with guide rails 206 at opposite ends. The inner walls of the upper and lower ends of the housing 203 are provided with rotating seats 205. The rotating seats 205 are rotatably mounted with balls 207 that are rolled on the inner wall of the guide rails 206 at opposite ends.

[0046] as well as;

[0047] The adjustment structure 300 includes guide plates 301 fixed to the inner walls of both sides of the frame 101 and slots 302 equally distributed on the inner walls of the guide plates 301.

[0048] Both ends of the vehicle power cabinet 102 are provided with sliders 303 that are slidably sleeved on the outer wall of guide plate 301. The inner wall of slider 303 is provided with rotating seat 307. A ball bearing 308 is rotatably installed inside rotating seat 307. Rolling grooves 304 are opened at both the front and rear ends of guide plate 301. The ball bearing 308 is rotatably installed inside rolling groove 304.

[0049] The slider 303 has mounting grooves 305 at both its front and rear ends. One end of the rotating seat 307 is located inside the mounting groove 305. A spring 306 connected to one end of the rotating seat 307 is provided on the inner wall of the mounting groove 305.

[0050] The fixed structure 200 and the adjusting structure 300 are used;

[0051] The frame 101 and the vehicle power cabinet 102 are made of 6061-T6 aluminum alloy. After aging treatment, the tensile strength reaches 310MPa, and the weight is lighter than that of traditional steel. At the same time, it has excellent corrosion resistance and is suitable for the humid and dusty environment of the vehicle. The worm gear 213, worm 212, and gear 214 are made of 45 steel with galvanized surface treatment. The tooth surface of the worm gear 213 is hardened by quenching. The meshing accuracy of the worm 212 and worm gear 213 reaches level 7, ensuring that there is no jamming in the transmission process and that the service life meets the needs of the entire vehicle life cycle. The upper tooth plate 210, lower tooth plate 209, insert plate 201, and insert block 202 are made of 5052 aluminum alloy. This material has high plasticity and fatigue resistance. The meshing surface of the tooth plate and gear 214 is anodized with a film thickness of 10-15μm, reducing the coefficient of friction to below 0.15 and reducing the operating force during adjustment. A single person can easily turn the torsion block 215.

[0052] The equidistant slots 103 at both ends and the bottom of the vehicle power cabinet 102 provide modular mounting positions for internal components such as inverters, fuse boxes, and terminals. The layout can be flexibly adjusted according to the power of the electrical equipment. For example, when adding a 12V vehicle refrigerator, the corresponding circuit relay can be quickly fixed through the slots 103. The support plate 104 with mounting holes at the rear end is used to strengthen the cabinet structure and prevent the cabinet from deforming due to the excessive weight of the internal components. The support plate 104 can distribute the longitudinal load. The slots 103, support plate 104 and cabinet are integrally formed and made of 6061-T6 aluminum alloy. The edges of the slots 103 are rounded to avoid scratching the cables during installation. The support plate 104 is 3mm thick and is connected to the cabinet by welding to ensure that it can stably support the internal equipment even when the vehicle accelerates to 3g during sudden braking.

[0053] The anti-slip textured torsion block 215 at one end of the rotating shaft 211 has a diameter of 30mm, which increases the friction of the hand and enables rapid rotation by hand. The adjustment force is ≤50N, and no wrench or other tools are required. It is suitable for emergency adjustment scenarios while the vehicle is in motion or outdoors. The stroke ports 204 at both ends of the housing 203 provide sliding guides for the insertion plate 201, limiting the maximum displacement of the insertion plate 201 and matching the depth of the slot 302 to prevent the insertion block 202 from over-extending and causing structural damage. The torsion block 215 is made of ABS engineering plastic injection molding with an anti-slip texture depth of 0.5mm and a temperature resistance range of -40℃~80℃, which is suitable for extreme vehicle environments. It is connected to the rotating shaft 211 through a keyway. The housing 203 is made of die-cast aluminum alloy with a wall thickness of 2mm and has good dimensional accuracy. The fit clearance between the stroke port 204 and the insertion plate 201 is 0.1-0.2mm to ensure that the insertion plate 201 slides smoothly without jamming.

[0054] The guide rails 206 of the upper toothed plate 210 and the lower toothed plate 209 cooperate with the ball bearings 207 of the housing 203 to convert the sliding friction of the toothed plates into rolling friction, thereby reducing the coefficient of friction and reducing the moving resistance of the upper toothed plate 210 and the lower toothed plate 209. This prevents the gear 214 from jamming due to excessive resistance during adjustment. The rotating seat 205 fixes the position of the ball bearings 207 to ensure that they are always in contact with the guide rails and will not fall off the track even when the vehicle is bumpy. The ball bearings 207 are made of high carbon chromium bearing steel with a diameter of 5mm, a hardness of HRC60-65, and a surface roughness of Ra0.02μm, ensuring smooth rolling and wear resistance. The rotating seat 205 is made of PA66 + glass fiber injection molding, which has high strength and self-lubricating properties. It is connected to the housing 203 by a snap-fit, which facilitates the later maintenance and replacement of the ball bearings.

[0055] The sliders 303 at both ends of the power cabinet 102 are sleeved on the outer wall of the guide plate 301, forming a longitudinally moving guide mechanism. The ball bearings 308 inside the slider 303 cooperate with the grooves 304 of the guide plate 301 to further reduce the moving resistance, so that the adjustment of the power cabinet within a 1-meter length can be completed in a few seconds. The grooves 304 are set at the front and rear ends of the guide plate 301 to limit the lateral displacement of the slider 303 and ensure that the plug 202 and the slot 302 are precisely aligned. The slider 303 is made of 6063 aluminum alloy extrusion molding, and the inner wall and the guide plate 301 have a clearance of 0.2-0.3mm to ensure smooth sliding. The ball bearings 308 are made of stainless steel with a diameter of 8mm, which are corrosion-resistant and non-magnetic to avoid interfering with the electronic components inside the power cabinet. The guide plate 301 is made of 6061-T6 aluminum alloy, and the length is customized according to the vehicle requirements, usually 1-2m. The grooves 304 are precision milled to ensure low noise when the balls roll.

[0056] The spring 306 inside the slider 303 connects to the rotating seat 307, ensuring that the ball 308 always elastically presses against the groove 304. This absorbs impact energy when the vehicle is bumpy, preventing the slider 303 from colliding with the guide plate 301 and causing abnormal noise or wear. At the same time, the slight extension and retraction of the spring 306 can compensate for the installation error of the guide plate 301, ensuring that the ball 308 always fits against the groove 304 and maintains smooth sliding. The spring 306 is made of piano wire with a diameter of 0.8mm and a free length of 15mm. The elastic force is stable when the compression is 3-5mm. The rotating seat 307 is made of the same material as the rotating seat 205 and has a 0.1mm clearance with the mounting groove 305, ensuring that the spring 306 does not shift laterally when under force.

[0057] When the rotating shaft 211 is rotated, the worm gear 212 drives the worm wheel 213 to rotate, causing the gear 214 on the mounting shaft 208 to rotate synchronously. This, in turn, drives the upper gear plate 210 and the lower gear plate 209 to slide in opposite directions, enabling the insertion block 202 to quickly connect or disconnect from the guide plate 301 slot 302. Compared to traditional screw fixing, this structure can lock and unlock without tools, improving adjustment efficiency. Furthermore, the multi-point cooperation between the insertion block 202 and the slot 302 can withstand greater longitudinal impact, making it suitable for vehicle bumpy scenarios. In the adjustment structure 300, the guide plate 301 is used for the longitudinal movement of the power cabinet. The guide plate 301 provides a guide trajectory, and the equally spaced slots 302 correspond to different fixed positions, allowing the power cabinet to be adjusted within the range of 0-500mm. The specific stroke depends on the length of the guide plate 301, adapting to the layout requirements of different electrical equipment, such as the switching between the kitchen and bathroom areas and the rest area of ​​the RV. This solves the problem of inconvenient adjustment of the traditional screw fixing method, and realizes the rapid longitudinal movement and stable locking of the power cabinet within the aluminum alloy frame 100. The worm gear 213 and worm 212 drive the gear 214 to cooperate with the toothed plate, driving the insertion plate 201 and the insertion block 202 to extend and retract.
