[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] The following is for reference. Figures 1-13 A power supply box 100 according to a first aspect embodiment of the present invention is described.

[0024] It should be noted that the power supply box 100 in this embodiment can be installed horizontally or vertically. The following description is based on horizontal installation. That is, the directions mentioned in this embodiment, such as up and down, left and right, front and back, as well as the top wall 13 and bottom wall, are all directions when installed horizontally.

[0025] like Figures 1-3 and Figures 9-10 As shown, according to the first aspect embodiment of the present invention, the power box 100 includes: a housing 10, a protective cover 20, and a stop rib 30. The housing 10 forms an inner cavity. The housing 10 includes a top wall 13. A mounting groove 14 recessed towards the cavity is formed on the top wall 13. At least one electrical component mounting hole 141 is formed on the bottom wall of the mounting groove 14, which is used to mount electrical components. The protective cover 20 is connected to the housing 10 and is used to cover or open the opening of the mounting groove 14. The stop rib 30 is arranged in the mounting groove 14 and extends circumferentially around the electrical component mounting hole 141. The stop rib 30 and the side wall of the mounting groove 14 together form a water collection tank 31. The water collection tank 31 is used to receive liquid that slides into the mounting groove 14 from the gap between the protective cover 20 and the housing 10. The water collection tank 31 has a water outlet end that extends through one side edge of the housing 10.

[0026] The housing 10 is mainly used to provide installation space for electrical components, power supply devices, etc. Specifically, the battery device is mainly arranged in the cavity, and the electrical components are mainly arranged in the mounting groove 14 of the top wall 13, and are fixed to the housing 10 and electrically connected to the power supply device through the electrical component mounting hole 141.

[0027] The protective cover 20 is mainly used to seal the mounting groove 14 to protect the electrical components installed in the mounting groove 14. Specifically, when it is necessary to operate or repair the electrical components, the protective cover 20 is opened; when the operation is completed, the protective cover 20 is closed to protect the electrical components in the mounting groove 14.

[0028] The stop rib 30 is used to stop the water flow, which can effectively prevent water from sliding down between the protective cover 20 and the box 10 from entering the electrical component installation area, thereby causing the electrical components to age or be damaged.

[0029] The water collection tank 31 is used to collect liquid that slips into the mounting groove 14 through the gap between the protective cover 20 and the box body 10. Since its outlet end extends through one side edge of the box body 10, the liquid that slips into the water collection tank 31 can be discharged from the water collection tank 31, so that it will not accumulate inside the mounting groove 14 and cause the electrical components to age. At the same time, it can also effectively prevent water from seeping into the power box after the sealing ring of the electrical components ages, thereby effectively reducing the risk of short circuit and damage to the battery device, and thus improving the service life and operational reliability of the battery device.

[0030] According to the power box 100 of this utility model, by setting the stop rib 30 and the side wall of the mounting groove 14 together to form a water collection groove 31, the liquid that slides into the mounting groove 14 can be discharged, and the water flow can also be stopped. This further reduces the probability of electrical components and circuits in the power box 100 coming into contact with water, thereby effectively reducing the risk of battery aging, short circuit and damage, and thus improving the service life and operational reliability of the battery device.

[0031] According to some embodiments of this utility model, such as Figures 9-10 As shown, the mounting groove 14 extends through one side wall of the housing 10 in the front-to-back direction. This facilitates the machining of the mounting groove 14 and the installation of the protective cover 20, thereby reducing the manufacturing difficulty of the entire power supply box 100 and increasing the manufacturing speed.

[0032] According to some embodiments of this utility model, such as Figures 9-10 As shown, the water collection tank 31 includes a water collection section 311 and a flow guiding section 312. The water collection section extends in the left-right direction. There are two flow guiding sections 312, which are respectively connected to the two ends of the water collection section 311. The flow guiding sections 312 extend in the front-back direction, with one end connected to the water collection section 311 and the other end extending towards and through one side edge of the housing 10. It can be understood that the water collection tank 31 is formed into a U-shaped structure, that is, the structure of the water collection tank 31 and the gap between the protective cover 20 and the housing 10 is arranged opposite to each other. In this way, the water collection tank 31 can collect water flow from all directions and will not cause water accumulation on the other side due to a unilateral design.

[0033] According to some embodiments of this utility model, such as Figures 9-10 As shown, in the direction from one end of the guide section 312 to the other end, the bottom wall of the guide section 312 extends downward at an angle. That is to say, the water collection section 311 is located relatively high, and the bottom wall of the guide section 312 extends downward at an angle, which can ensure that the water accumulated inside the water collection section 311 can be completely drained.

[0034] For example, in the direction from one end of the guide section 312 to the other end, the bottom wall of the mounting groove 14 extends downward at an angle. In this way, when water enters the electrical component mounting area from the gap between the protective cover 20 and the housing 10, it will be stopped by the stop rib 30, so that it will not flow to the position of the electrical component mounting hole 141 and enter the housing 10 through the electrical component mounting hole 141. Instead, it can be discharged outward through the bottom wall of the mounting groove 14. In this way, the waterproof performance of the power box 100 can be further improved.

[0035] According to some embodiments of this utility model, such as Figure 12 As shown, mounting posts 21 are formed on the left and right sides of the protective cover 20, and shaft holes are formed on the side wall of the mounting groove 14. The mounting posts 21 are rotatably fitted into the shaft holes. That is, the protective cover 20 is rotatably connected to the mounting groove 14 to realize the opening and closing of the protective cover 20 with respect to the opening of the mounting groove 14. The space required for rotation is smaller than that for linear movement. Therefore, by using the mounting posts 21 to cooperate with the shaft holes to realize the opening and closing of the protective cover 20, the integration of the power supply box 100 can be further improved.

[0036] Optionally, the end of the mounting post 21 away from the protective cover 20 is chamfered, which facilitates the installation of the protective cover 20 and the housing 10. In addition, the power box 100 also includes a washer, which is arranged on the radially outer side of the mounting post 21 and abuts against the inner wall of the protective cover 20 and the mounting groove 14. This can further reduce the contact area between the protective cover 20 and the inner wall of the mounting groove 14, thereby increasing the smoothness of the switch of the protective cover 20.

[0037] Optionally, in some embodiments, the protective cover 20 has a recessed groove facing the mounting slot 14, and multiple anti-slip strips are formed on the bottom wall of the groove. The groove and anti-slip strips provide a stable point of force application for the operator, increasing the stability of the operator's hand holding the protective cover 20. In other embodiments, the protective cover 20 has a handle, which is formed as an upwardly protruding portion to provide a stable point of force application and support one-handed operation. Furthermore, all edges and corners of the protective cover 20 are rounded, improving visual aesthetics while effectively eliminating the risk of scratches during operation.

[0038] Optionally, the protective cover 20 is made of a weather-resistant translucent material, which can resist environmental corrosion, clearly display the status of the internal indicator lights, and provide reliable physical protection for the switch assembly.

[0039] According to some embodiments of this utility model, such as Figures 1-10As shown, the housing 10 includes a first housing 11 and a second housing 12. The first housing 11 has a first receiving cavity 111 with a first opening in the vertical direction. The second housing 12 is located above the first housing 11 and is used to cover the first opening. The second housing 12 has a second receiving cavity inside, which, together with the first receiving cavity 111, defines the receiving cavity. The second receiving cavity has a second opening on the side facing the first housing 11 in the vertical direction. A mounting groove 14 is formed on the side of the second housing 12 opposite to the first housing 11. The structure of the first housing 11 and the second housing 12 simplifies the manufacturing difficulty of the power supply box 100 and the assembly difficulty of the battery device, thereby increasing the assembly speed of the battery device. Simultaneously, the structure of the first receiving cavity 111 and the second receiving cavity can increase the installation space of the power supply device within the entire internal space of the power supply box 100, and further reduce the weight of the entire power supply box 100.

[0040] For example, refer to Figure 4 The first housing 11 has a rectangular overall shape with rounded corners. A first mounting part 17 is formed on the front wall of the first housing 11. The first mounting part 17 extends along the left and right sides of the first housing 11. The first mounting part 17 has a plurality of spaced first mounting holes 171 to adapt to different installation spaces and provide users with a more convenient installation experience.

[0041] For example Figure 5 As shown, the plurality of first mounting holes 171 include round holes and oblong holes. The oblong holes can be used in compact areas to facilitate fine-tuning of the position, while the round holes can be used in open areas to ensure stability. In addition, at the center of the edge of the first mounting portion 17, there is an outwardly protruding trapezoidal structure that is connected to the first mounting portion 17 by rounded corners, and a keyhole is formed here. This keyhole is mainly used for the hanging function so that the power box 100 can be installed vertically.

[0042] It should be noted that the back of the multiple first mounting holes 171 is designed with an outward flare, which allows water to drain more smoothly.

[0043] Optional, refer to Figure 5 The rear end of the first housing 11 also forms two symmetrical second mounting portions 18, each a small ear structure, whose appearance is connected to the outer surface of the first housing 11 by rounded corners; each small ear has a shaped hole. Thus, when installing the power supply box 100, these two small ears can also serve as mounting portions to assist in fixing the power supply box 100. It should be noted that these two small ears are mainly used when the power supply box 100 is installed vertically, cooperating with the keyhole to fix the power supply box 100.

[0044] Optional, refer to Figure 7 The bottom surface of the first box 11 is designed with reinforcing ribs, which can significantly improve the load-bearing capacity of the first box 11 while reducing the overall weight of the box 10. At the same time, it can also effectively avoid problems such as mold shrinkage.

[0045] Optionally, a wiring hole 118 is also formed on the side wall of the first housing 11 to allow the internal wiring harness of the battery device to pass through and connect to other devices. It should be noted that a waterproof connector or waterproof coil is provided at the wiring hole 118, and the wiring harness is led out through the waterproof connector or waterproof coil, which can further improve the protection performance of the power box 100.

[0046] According to some embodiments of this utility model, such as Figures 5-6 and Figure 11 As shown, a plurality of first connecting portions 119 are formed on the first housing 11, and a plurality of second connecting portions 121 corresponding one-to-one with the plurality of first connecting portions 119 are formed on the second housing 12. In the vertical direction, the first connecting portions 119 and the corresponding second connecting portions 121 are arranged facing each other. The first housing 11 and the second housing 12 are fastened together by fasteners passing through the first connecting portions 119 and the second connecting portions 121. The fasteners have a relatively simple structure, which reduces the manufacturing difficulty and cost of the power supply box 100.

[0047] It should be noted that in this embodiment, the first box 11 and the second box 12 are assembled using a bottom-up locking process. That is, after assembling the internal components of the box 10, the top cover is closed, the whole thing is turned upside down, and finally the screws are locked in from the bottom of the box 10. This process can hide most of the fastening points at the bottom of the box, which can significantly improve the visual integrity and simplicity of the product.

[0048] The power supply box 100 further includes a first sealing member, which extends circumferentially along the first housing 11 in an annular shape and seals against the space between the first housing 11 and the second housing 12. A first connecting portion 119 and a second connecting portion 121 are arranged radially outward from the first sealing member. The first sealing member seals the gap between the first housing 11 and the second housing 12 to improve the overall sealing performance of the power supply box 100. It should be noted that the first sealing member can be a sealing ring, for example, an elastic silicone ring.

[0049] Optional, refer to Figure 11 A sealing groove 122 is formed on the inner wall surface of the second receiving cavity, and at least a portion of the first sealing element is fitted within the sealing groove 122. The sealing groove 122 restricts the movement of the first sealing element, thereby effectively preventing the probability of the first sealing element misalignment.

[0050] Optionally, a rib extending around the first opening is formed on the periphery of the first opening, and the first seal is fitted above the rib, with part of the rib fitting within the sealing groove 122. In this way, the first seal can be fully compressed to form a uniform sealing interface, completely preventing water from seeping in along the seam, thereby improving the waterproof performance of the power box 100.

[0051] According to some embodiments of this utility model, such as Figures 5-6 As shown, multiple first connecting portions 119 are respectively arranged at the corner positions of the first housing 11. The first housing 11 also defines a drainage cavity 15 spaced apart from the first receiving cavity 111. The drainage cavity 15 is located between the first connecting portions 119 and the first receiving cavity 111, and a drainage hole 151 penetrating the bottom wall is formed on the bottom wall of the drainage cavity 15. In this way, water that seeps into the receiving cavity from the gap between the first housing 11 and the second housing 12 can be drained, thereby improving the waterproof performance of the electrical control box.

[0052] Optional, refer to Figure 5 The drainage hole 151 is formed as an elongated hole, which includes a first hole section and a second hole section. The first hole section is connected to the upper side of the second hole section. In the direction from top to bottom, the cross section of the first hole section is formed as an inverted trapezoid, and the cross section of the second hole section is formed as a regular trapezoid. That is to say, the first hole section is conducive to the inflow of water, and the second hole section is conducive to the outflow of water.

[0053] For example, Figure 5 As shown, the length of the oblong hole is 12mm-15mm, the width is 2mm-5mm, and the four corners are rounded with a radius of 1mm-2mm. The inner wall of the first hole section is formed with a guide radius of 0.5mm-1mm chamfer, and the inner wall of the second hole section is formed with a guide radius of 0.5mm-1mm chamfer.

[0054] It should be noted that the dimensions of the drainage cavity 15 can be designed according to actual conditions, and there are no restrictions here. For example Figure 5 As shown, the four drainage cavities 15 can be designed as a structure with two relatively large cavities and two relatively small cavities. For example, the small cavity can be designed as a cavity with a length and width of 10mm-20mm, and the large cavity can be designed as a cavity with a length and width of 30mm-40mm, or a cavity with a width of 10mm-20mm.

[0055] Optionally, a connecting hole is formed on the side wall of the first receiving cavity 111, which connects to the drainage cavity 15. The connecting hole is arranged opposite to the wire outlet hole 118. The connecting hole is mainly used for installing wire harness. Specifically, a waterproof wire guide coil is also installed in the connecting hole to prevent water from entering the first receiving cavity 111, thereby further improving the safety of the battery device.

[0056] According to some embodiments of this utility model, such as Figures 5-6 As shown, the first housing 11 further includes a first partition 112, which divides the first receiving cavity 111 into a first cavity 113 and a second cavity 114. The first cavity 113 is configured for installing a power supply device, and the second cavity 114 is configured for arranging wiring harnesses. The second cavity 114 is directly opposite the mounting slot 14 in the vertical direction. This design facilitates layout, reduces the use of wiring harnesses, and improves the overall neatness of the assembled battery device, reducing the risk of short circuits caused by messy wiring harnesses. This, in turn, enhances the ease of maintenance and reliability of the battery device.

[0057] For example Figure 6 As shown, the first partition 112 is U-shaped, and its two ends are connected to the rear sidewall of the first receiving cavity 111 respectively. The interior of the first partition 112 defines the second cavity 114, and the exterior of the second partition 116 and the inner peripheral wall of the first receiving cavity 111 define the first cavity 113.

[0058] Optionally, a third connecting part extending vertically is connected to the middle of the rear sidewall of the second cavity 114. The third connecting part is formed as a cylindrical structure tangent to the rear sidewall. A threaded hole is formed at the top of the third connecting part to connect a bolt for pressing the sealing strip.

[0059] According to some embodiments of this utility model, such as Figure 6 As shown, the first cavity 113 has two sidewalls spaced apart in the left-right direction, which are called first sidewalls 115. Multiple limiting ribs 1151 are formed at the ends of the two first sidewalls 115 furthest from the second cavity 114. This means that the battery device will not be installed flush against the wall, and a certain gap will be created between it and the inner wall of the first cavity 113. Thus, when the height of the battery device is higher than the height of the first receiving cavity 111, interference between the battery device and the sealing groove 122 of the first housing 11 can be effectively avoided, thereby improving the sealing performance between the first housing 11 and the second housing 12.

[0060] For example, the number of limiting ribs 1151 can be two, three or more.

[0061] According to some embodiments of this utility model, such as Figures 5-6As shown, the first housing 11 further includes a second partition 116 and a third partition 117. The second partition 116 and the third partition 117 are arranged within the first cavity 113 and spaced apart in the left-right direction. The second partition 116 and the third partition 117 divide the first cavity 113 into a first mounting area 1131, a second mounting area 1132, and a third mounting area 1133. The first mounting area 1131 and the third mounting area 1133 are respectively arranged on both sides of the second mounting area 1132 in the left-right direction. The first mounting area 1131 is configured to fix the PCB circuit board, the second mounting area 1132 is configured to fix the battery, and the third mounting area 1133 is configured to fix the battery protection board. Specifically, when assembling the battery device, the battery, circuit board, and control board can be installed according to the preset areas, which can improve the assembly speed of the battery device; at the same time, it can also isolate the circuit board from the battery, thereby effectively avoiding the problem of short circuit in the battery device caused by contact between the circuit board and the battery.

[0062] For example Figure 6 As shown, there are two second partitions 116, which are respectively connected to the two inner walls of the first cavity 113 in the front-back direction and are arranged opposite to each other in the front-back direction. The two second partitions 116 and the adjacent first side wall 115 define a first mounting area 1131. There are also two third partitions 117, which are respectively connected to the two inner walls of the first space in the front-back direction and are arranged opposite to each other in the front-back direction. The two third partitions 117 and the adjacent first side wall 115 define a third mounting area 1133. The two second partitions 116 and the two third partitions 117 define a second mounting area 1132.

[0063] Optionally, the cross-sectional dimensions of the second partition 116 and the third partition 117 gradually increase in the vertical direction. That is, the width of the first partition 112 and the second partition 116 gradually changes linearly from top to bottom, and the overall cross-section is trapezoidal. This can improve the installation stability of the second partition 116 and the third partition 117. At the same time, the top of the second partition 116 and the third partition 117 is rounded, which can effectively improve the safety of other components during internal installation.

[0064] According to some embodiments of this utility model, such as Figure 13As shown, the power supply box 100 also includes a substrate 40, on which a plurality of matrix-arranged mounting holes 41 are arranged. The substrate 40 is fixed within the first mounting area 1131 and is configured to fix the PCB circuit board. It should be noted that in the prior art, the PCB circuit board is usually fixed to the housing by studs at the bottom of the power supply box. However, the specifications of the studs and the PCB board, such as hole diameter and thread structure, are prone to mismatch, leading to assembly difficulties. Conventionally, this requires re-drilling holes or redesigning the PCB board for adaptation, resulting in high rework costs and poor reliability. In this embodiment, the PCB circuit board is fixed within the first housing 11 by the substrate 40, and the plurality of mounting holes 41 formed on the substrate 40 allow the substrate 40 to easily adapt to circuit boards of different sizes. This increases the adaptability of the power supply box 100, reduces the installation difficulty of the PCB board and the power supply box 100, thereby increasing the assembly speed of the entire battery device, reducing the production cost of the entire battery device, and improving the reliability of the battery device.

[0065] Optionally, the holes at the four corners of the array and at both ends of the central axis are filled with solid areas. This can meet the requirements of injection mold manufacturing, prevent ejector pin interference, and improve the success rate of substrate 40 preparation.

[0066] According to some embodiments of this utility model, such as Figures 1-3 As shown, the upper surface of the top wall 13 is formed as an upwardly convex arc surface. In this way, when water falls on the top wall 13, the top wall 13 can quickly guide the water flow naturally from the high point to the edge, thereby realizing the surface hydrophobic function of the power box 100.

[0067] Optionally, when the protective cover 20 is closed, the upper surface of the protective cover 20 and the upper surface of the top wall 13 form a continuous arc surface, which makes the entire power box 100 visually coordinated and aesthetically pleasing.

[0068] According to some embodiments of this utility model, such as Figures 1-3 As shown, the top wall 13 and bottom wall of the enclosure 10 have extended edges 16 extending circumferentially around the enclosure 10. One end of the extended edge 16 is connected to the enclosure 10, and the other end extends toward the side away from the receiving cavity. A drainage channel is formed between the two extended edges 16. In this way, when the power box 100 is installed horizontally, the extended edge 16 of the top wall 13 can shield the lower part of the entire power box 100, thereby reducing the risk of rainwater entering through the gaps in the power box 100. When the power box 100 is installed vertically, the drainage channel formed between the extended edges 16 of the top wall 13 and the bottom wall can prevent water accumulation while ensuring that the drainage path is controllable.

[0069] Optionally, the extended edge 16 is seamlessly connected to the peripheral wall by a smooth, rounded corner to enhance the overall aesthetics of the power supply box 100.

[0070] The battery device according to a second aspect of the present invention includes: a power supply box 100, a power supply device, and electrical components according to a first aspect of the present invention. The power supply device is arranged in a receiving cavity and includes: a battery, a battery protection board, and a PCB circuit board. The electrical components are disposed in a mounting groove 14 and installed at the position of the electrical component mounting hole 141, and are connected to the power supply device.

[0071] The power supply box 100 is a component that provides installation space and protection for power supply devices and electrical components, which can improve the safety and service life of power supply devices and electrical components. The power supply device is a generator or power supply device that can supply power to other components so that they can work normally. The electrical components are mainly used to control or display the working status of the power supply device. For example, the electrical components can be switches, displays, etc.

[0072] It should be noted that the power supply box 100 can be made of PC / ABS material. The excellent weather resistance of PC / ABS allows the power supply box 100 to withstand ultraviolet radiation, temperature fluctuations, and environmental humidity. Even when used outdoors or in environments with varying conditions, it can maintain structural integrity and appearance stability for a long time, ensuring a long service life and reliability. Furthermore, the power supply box 100 has certain flame-retardant properties, for example, it can meet UL94 V-0 flame-retardant standards. This enhances the safety of the power supply box 100 and effectively reduces the risk of fire caused by electrical faults.

[0073] The vehicle according to this utility model improves the overall performance of the battery device by providing the power box 100 described in the first aspect.

[0074] According to some embodiments of this utility model, there are multiple electrical component mounting holes 141, which are arranged at intervals along the left-right direction. The electrical components include a switch and multiple indicator lights, each corresponding to and fixed to one of the mounting holes 141. The switch controls the opening and closing of the battery device; the indicator lights display the operating status of the battery device, allowing the user to intuitively observe its working status and promptly detect and repair any problems, thereby reducing other issues caused by damage.

[0075] It should be noted that multiple indicator lights can have the same or different functions. For example, multiple indicator lights can include fault indicator lights, normal operation indicator lights, activity level indicator lights, etc. There are no restrictions here.

[0076] Optional, for example Figures 9-11As shown, there are four electrical component mounting holes 141. The four electrical component mounting holes 141 include a switch mounting hole and three indicator light mounting holes. That is, there are three indicator lights in this embodiment. The three indicator lights are used to display the power supply status, working activity and fault alarm, or to display the working mode and charging status of the battery device. This setting not only ensures the clear communication of the basic status, but also reserves the space for flexible adjustment for different industries or customer needs. It can adapt to diverse application scenarios without changing the physical structure, thereby further improving versatility.
