Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and more specifically, it relates to an electrical control box and an electric loader. Background Technology

[0002] Compared to gasoline-powered vehicles, electric vehicles have more and more complex electrical components and parts. In addition, the space occupied by the power battery is larger than that of the engine, making the internal space of electric vehicles very limited, which brings inconvenience to the installation and maintenance of electrical components. The battery is the core component that ensures the starting of the equipment and the power supply, and it requires frequent maintenance. Moreover, the special structure of the battery makes the current installation and fixing structure relatively complex.

[0003] Currently, electrical components in electric vehicles are installed in different locations throughout the vehicle according to their functions; the battery is placed separately in the battery box and either mounted on the side or placed in the trunk, which presents the following problems: (1) The installation locations of the electrical components are relatively scattered, making it inconvenient to repair when problems occur; (2) The battery installation structure is complex and inconvenient to install; (3) Due to the dispersed arrangement of electrical components and batteries, the overall space utilization rate of the vehicle is relatively small. Utility Model Content

[0004] The purpose of this utility model is to provide an electrical control box and an electric loader, which aims to solve the problems of inconvenient installation and maintenance and low space utilization caused by the current scattered layout of electrical components in vehicles and the scattered layout of batteries and electrical components.

[0005] Firstly, to achieve the above objectives, the technical solution adopted by this utility model is: to provide an electrical control box, comprising: The electrical control box body includes at least one openable side panel and / or top cover and a partition plate disposed within the electrical control box body, the partition plate dividing the electrical control box body into a battery mounting cavity and an electrical component mounting cavity; A storage battery is installed within the battery mounting cavity and positioned by a first positioning structure within the battery mounting cavity; and The controller is installed inside the electrical component mounting cavity and positioned by a second positioning structure inside the electrical component mounting cavity.

[0006] Compared with the prior art, the beneficial effects of the electrical control box provided by this utility model are as follows: (1) Electrical components are easy to inspect, faults can be easily and quickly eliminated, and repairs can be carried out quickly. By integrating electrical components and batteries scattered throughout the vehicle into a single electrical control box, when a fault occurs in the vehicle's electrical control, the control box can be opened first. Without moving the components, the electrical components inside can be inspected one by one, thus eliminating most electrical faults. This allows for quick troubleshooting and timely repair, reducing troubleshooting time and avoiding the time-consuming and labor-intensive process of inspecting different parts of the vehicle.

[0007] During maintenance, the top cover or side panel of the electrical control box can be opened to facilitate the maintenance of the electrical components inside the box.

[0008] (2) The battery is easy to install. The battery and electrical components are integrated into the electrical control box and installed in the battery mounting cavity, which is separated from the control box by a partition plate. The battery does not interfere with the electrical components installed in the control box. There is no need to set up an external mounting structure for the battery. During installation, the battery can be positioned in the control box by the first positioning structure set in the battery mounting cavity, making installation simple and convenient.

[0009] (3) Due to the centralized arrangement of electrical components, especially the centralized arrangement of batteries, the space occupied in the whole vehicle due to the dispersed arrangement is greatly reduced, which can effectively improve the space utilization of the whole vehicle. Moreover, after the centralization, the corresponding lines can be organized and routed in a centralized manner, which can also save space and facilitate maintenance and installation.

[0010] In conjunction with the first aspect, in one possible implementation, the partition plate is parallel to the upper cover plate so that the battery mounting cavity and the electrical component mounting cavity are arranged vertically. The first positioning structure is disposed on the top of the partition plate; the battery is mounted on the partition plate, and the top cover is detachably mounted on the side plate; At least one of the side plates is provided with an inspection window at the position corresponding to the electrical component mounting cavity, and the inspection window is provided with a removable side cover plate.

[0011] The above-mentioned technical solution is a preferred arrangement method. By having the partition plate parallel to the upper cover plate, the battery mounting cavity and the electrical component mounting cavity are arranged vertically. Then, the battery can be installed on the partition plate, and a maintenance window is provided on the side plate to facilitate the maintenance of the electrical components in the cavity and improve the convenience of maintenance.

[0012] In conjunction with the first aspect, in one possible implementation, the first positioning structure includes: A positioning corner plate located at the corner of the battery is fixed to the partition plate; A limiting block positioned on the side of the battery is fixed to the partition plate; and The upper pressure plate is pressed against the battery via a connecting rod connected to the limiting block.

[0013] In the above technical solution, the positioning angle plate, limiting block, connecting rod and upper pressure plate can restrict the battery in different directions, so that the battery can be installed in the main body of the electrical control box. This method of installing the battery does not require any installation structure on the outside of the battery, such as the ear plate, bolt holes and other structures for installation and fixing on the outside of the battery, which also simplifies the structure of the battery itself.

[0014] In conjunction with the first aspect, in one possible implementation, an installation space is formed between the upper pressure plate and the upper cover plate, and a chassis power distribution box, a DC contactor, and a chassis fuse box are installed on the upper pressure plate.

[0015] The above technical solution makes full use of the space between the battery and the top cover to integrate the chassis power distribution box, DC contactor and chassis fuse box. Of course, according to the layout of the electrical components in the whole machine, corresponding electrical components can also be installed on the upper pressure plate, and it is not limited to the chassis power distribution box, DC contactor and chassis fuse box installed.

[0016] In conjunction with the first aspect, in one possible implementation, the upper pressure plate is provided with a plurality of support bends for mounting different electrical components.

[0017] In the above technical solution, the support bend plate can maintain a certain gap between the installed electrical components and the upper pressure plate, which plays a certain role in heat dissipation of the electrical components and avoids heat transfer between the battery and the electrical components, thus affecting the sensitivity of the electrical components.

[0018] In conjunction with the first aspect, in one possible implementation, a rubber pad is provided between the upper pressure plate and the battery.

[0019] In the above technical solution, by placing a rubber pad between the battery and the upper pressure plate, the hard-hard contact between the battery and the upper pressure plate is transformed into a soft-hard contact, avoiding the risk of damage to the battery when the upper pressure plate is pressed down. At the same time, the rubber pad also has the function of insulation and heat insulation between the battery and electrical components, which can prevent mutual interference between the battery and electrical components.

[0020] In conjunction with the first aspect, in one possible implementation, the second positioning structure includes: The support block fixed to the side plate; and A support plate that is positioned between the partition plate and the base plate of the electrical control box body; The controller is divided into a central controller and a vehicle controller. The central controller is mounted on the support plate, and the vehicle controller is mounted on the support block.

[0021] In the above technical solution, the second positioning structure positions and supports the electrical components installed in the electrical component mounting cavity. In this application, the central controller and the vehicle controller are centrally installed, and the status of the controller inside the cavity can be observed through the corresponding inspection window on the side panel. By installing the controllers separately and creating gaps between them, mutual interference of heat and signals between the different controllers is reduced.

[0022] The support plate, which is positioned between the partition plate and the base plate, also serves to support the battery and enhance the overall strength of the electrical control box.

[0023] In conjunction with the first aspect, in one possible implementation, the support plate has flanges on opposite sides, with the upper and lower ends of the flanges respectively supported by the partition plate and the base plate. The flanges on both sides of the support plate further enhance its supporting strength.

[0024] In conjunction with the first aspect, in one possible implementation, the outer side of the side plate is provided with a wing plate for connection with the vehicle body frame.

[0025] In the above technical solution, the wing plate facilitates the installation of the electrical control box on the vehicle.

[0026] Secondly, this utility model embodiment also provides an electric loader, including the aforementioned electrical control box; wherein the electrical control box is mounted on the rear frame of the electric loader.

[0027] The electric loader provided in this application integrates electrical components and batteries into a single electrical control box. In the event of an electrical fault, the control box can be opened to inspect and repair each component individually. This facilitates inspection, allows for quick fault location identification and timely repair, reduces troubleshooting time, and avoids the time-consuming and labor-intensive process of repairing different parts of the vehicle. Furthermore, the battery is directly installed within the control box, making installation simple and convenient. In particular, integrating electrical components and batteries into a single control box reduces the space occupied within the vehicle and improves the utilization rate of the interior space.

Detailed Implementation

[0030] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Electric loaders require numerous electrical components, which are typically distributed near the controlled mechanism and thus scattered throughout the machine. During inspection and maintenance, each component must be opened and closed individually, wasting time and space. Furthermore, this dispersed arrangement consumes considerable internal space, and the separately installed battery is inconvenient and also occupies limited space. To optimize the internal space of the electric loader and improve troubleshooting efficiency, this application proposes integrating electrical components and the battery into a single control box. This allows for centralized inspection, one-time installation, and improved space utilization. See the implementation method below for details.

[0033] Please refer to the following: Figures 1 to 8 As shown, the electrical control box 1 provided by this utility model will now be described. The electrical control box 1 includes: an electrical control box body 3, a storage battery 11, and a controller. The electrical control box body 3 includes at least one openable side panel and / or top cover 7 and a partition plate 15 disposed within the electrical control box body 3. The partition plate 15 divides the electrical control box body 3 into a battery mounting cavity and an electrical component mounting cavity. The storage battery 11 is installed in the battery mounting cavity and positioned by a first positioning structure within the battery mounting cavity. The controller is installed in the electrical component mounting cavity and positioned by a second positioning structure within the electrical component mounting cavity.

[0034] The electrical control box 1 provided by this utility model has the following advantages compared with the prior art: (1) Electrical components are easy to inspect, faults can be easily and quickly eliminated, and repairs can be carried out quickly. Some electrical components and batteries 11, which are scattered in different locations of the vehicle, are integrated into an electrical control box 1. When the electrical control of the vehicle fails, the electrical control box 1 can be opened first. Without moving the components, the electrical components in the electrical control box 1 can be checked one by one. This can eliminate most electrical faults, quickly locate the fault, and repair it in time, reducing the time spent on troubleshooting and repairing the vehicle and avoiding the time-consuming and laborious problems caused by repairing the vehicle in different locations.

[0035] The side panel or top cover 7 that can be opened facilitates the inspection of electrical components inside the electrical control box 1. During maintenance, the top cover 7 or side panel of the electrical control box 1 can be opened to facilitate the maintenance of electrical components inside the electrical control box 1.

[0036] (2) Battery 11 is easy to install The battery 11 is integrated with the electrical components in the electrical control box 1 and installed in the battery mounting cavity that is separated from the electrical control box 1 by the partition plate 15. It does not interfere with the electrical components installed in the electrical control box 1. There is no need to set up an external mounting structure for the battery 11. During installation, the battery 11 can be positioned in the electrical control box 1 by the first positioning structure set in the battery mounting cavity, which makes the installation simple and convenient.

[0037] (3) Due to the centralized arrangement of electrical components, especially the centralized arrangement of the storage battery 11, the space occupied in the whole vehicle due to the dispersed arrangement is greatly reduced, which can effectively improve the space utilization of the whole vehicle. Moreover, after the centralization, the corresponding lines can be centrally organized and routed, which can also save space and facilitate inspection and installation.

[0038] The electrical control box body 3 of this application includes a side enclosure surrounding the four sides. The side enclosure has four side plates connected in sequence to form a closed enclosure, a bottom plate 18 fixed to the lower end of the side plates, and an upper cover plate 7 fixed to the upper end of the side plates. Optionally, the side enclosure is formed by welding or bolting the four side plates in sequence, or by bending sheet metal to form a semi-closed enclosure with three sides closed and one side open. An openable side plate is fixed at the opening (the electrical control box body 3 shown in the figure of this application has this structure).

[0039] For ease of inspection, an openable side panel or top cover 7 is provided; the following are possible interpretations for the electrical control box body 3 including at least one openable side panel and / or top cover 7: When the partition plate 15 is fixed inside the side plate parallel to the upper cover plate 7, separating the battery mounting cavity and the electrical component mounting cavity into an upper and lower arrangement, one side plate can be opened while the upper cover plate 7 is fixed. During inspection, the movable side plate can be opened to inspect the electrical components, and it also facilitates the installation and replacement of electrical components and the battery 11.

[0040] When the partition plate 15 is vertically fixed between the upper cover plate 7 and the bottom plate 18, the battery mounting cavity and the electrical component mounting cavity are separated into left and right or front and back arrangements. At this time, the upper cover plate 7 is opened and the side plate can be fixed. When inspecting, opening the upper cover plate 7 allows both mounting cavities to be seen at the same time, which facilitates inspection, installation and replacement.

[0041] Regardless of the arrangement of the battery mounting cavity and the electrical component mounting cavity, the design allows the top cover 7 to be opened and one of the side panels to be opened, enabling inspection of the battery 11 and electrical components inside the electrical control box body 3 from different angles.

[0042] Therefore, the purpose of the openable side panel and top cover 7 is that when a fault occurs, it is not necessary to remove the electrical control box 1 from the whole machine. The inspection and replacement operations can be carried out simply and conveniently by opening the side panel and top cover 7.

[0043] In the above scheme, the upper cover plate 7 can be fastened to the side plate with bolts, and the bolts can be removed, thus allowing the upper cover plate 7 to be opened; the upper cover plate 7 can also be fastened to the side plate by snap-fitting. In this case, snap-fitting claws can be provided around the upper cover plate 7, and snap-fitting holes can be provided on the inner or outer side of the upper end of the side plate. The opening side plate can be fastened by bolts, snap-fitting, or other methods to facilitate disassembly and opening; the opening side plate and the fixed side plate can be connected by hinges, and then fastened on the opposite side by bolts or snap-fitting.

[0044] As a preferred method of opening, an inspection window can be opened on the side panel, and a side cover plate 8 can be installed on the inspection window by bolts or clips. During maintenance, the side cover plate 8 can simply be removed.

[0045] It should still be noted that electric loaders have a large number of electrical components, which cannot all be arranged in the electrical control box body 3. However, in terms of design, the electrical components located near the battery 11 can be integrated into the electrical control box body 3 based on the design location of the battery 11. This is the case in this application, where the controller and the battery 11 are integrated into one electrical control box body 3. Alternatively, the electrical components of the whole machine can be integrated according to function, area, etc. For example, the electrical components of the whole machine can be integrated into several electrical control box bodies 3, which can realize rapid maintenance and improve the effective utilization of space.

[0046] In some embodiments, the following is combined with Figure 1 The embodiment shown is a preferred configuration of the electrical control box 1 and its internal electrical components and battery 11. In this embodiment, the partition plate 15 is parallel to the upper cover plate 7 so that the battery mounting cavity and the electrical component mounting cavity are arranged vertically. At this time, the upper cover plate 7 is fixed to the side plate by bolts. A nut seat 22 is fixed to the inner side of the upper end of the side plate. The nut seat 22 is provided with a threaded hole. The bolt passes through the through hole on the upper cover plate 7 and is screwed into the threaded hole, so that the upper cover plate 7 can be fixed to the side plate.

[0047] The position of the first positioning structure is determined by the position of the partition plate 15, that is, the first positioning structure is set on the partition plate 15; the battery 11 is installed on the partition plate 15, and the upper cover plate 7 is detachably installed on the side plate; the battery 11 is positioned on the partition plate 15 by the first positioning structure, and there is a gap between the battery 11 and the side plate. On the one hand, it is convenient for installation, wiring and maintenance, and on the other hand, it also provides space for heat dissipation when the battery 11 is working.

[0048] At least one side panel has an inspection window located at the position corresponding to the electrical component mounting cavity, and the inspection window is equipped with a removable side cover plate 8. For example, this application has inspection windows on two side panels respectively (see...). Figure 4 This allows for easy inspection and maintenance of electrical components inside the cavity from different angles. Furthermore, the arrangement of various electrical components within the cavity facilitates targeted inspection and maintenance of different components, thus enhancing the convenience of maintenance.

[0049] The above embodiments provide a preferred arrangement of the battery mounting cavity and the electrical component mounting cavity. In the preceding discussion, the arrangement of the battery mounting cavity and the electrical component mounting cavity in a left-right manner was also given.

[0050] In some embodiments, the first positioning structure is referred to Figure 2 , Figures 5 to 8 As shown, it includes: a positioning angle plate 13, a limiting block 14, and an upper pressure plate 5.

[0051] The positioning angle plate 13 is fixed on the partition plate 15 and positioned at the corner of the battery 11 to limit the battery 11 in the front, back, left and right directions. In this application, positioning angle plates 13 are provided at all four corners of the battery 11 to ensure that the battery 11 will not shake inside the electrical control box body 3 when the whole machine vibrates and bumps.

[0052] The limiting block 14 is fixed on the partition plate 15 and positioned on the side of the battery 11, which can further limit the battery 11 in the front, back, left and right directions; the limiting block 14 also provides a supporting base for the upper pressure plate 5.

[0053] Specifically, the upper pressure plate 5 is pressed against the battery 11 by the connecting rod 12 connected to the limiting block 14, and the upper pressure plate 5 limits the battery 11 to the partition plate 15. In this way, the positioning angle plate 13, the limiting block 14, the connecting rod 12 and the upper pressure plate 5 can restrict the battery 11 in different directions, so that the battery 11 can be installed in the electrical control box body 3. This method of installing the battery 11 does not require any installation structure on the outside of the battery 11, such as the ear plate, bolt holes and other structures for installation and fixing on the outside of the battery 11, which also simplifies the structure of the battery 11 itself.

[0054] The connecting rod 12 can be a double-ended bolt. The lower end of the connecting rod 12 is screwed onto the limiting block 14, and the upper end passes through the through hole on the upper pressure plate 5. Then, the fixing nut 6 is tightened.

[0055] When installing the battery 11, simply place the battery 11 into the frame formed by the positioning angle plate 13 and the limiting block 14, then place the upper pressure plate 5 on top of the battery 11 and let the connecting rod 12 pass through the through hole on the upper pressure plate 5, and then lock it with a nut or snap ring. There is no need for the upper cover plate 7 to limit the battery 11.

[0056] This method of installing the battery 11 through the first positioning structure makes the installation of the battery 11 more convenient.

[0057] In some embodiments, based on the above structure, combined with Figure 2 As shown, the upper pressure plate 5 and the upper cover plate 7 form an installation space, and the chassis distribution box 23, DC contactor 25 and chassis fuse box 26 are installed on the upper pressure plate 5.

[0058] The above technical solution makes full use of the space between the battery 11 and the upper cover 7 to integrate the chassis distribution box 23, DC contactor 25 and chassis fuse box 26. Of course, according to the arrangement of electrical components in the whole machine, corresponding electrical components can also be installed on the upper pressure plate 5, and are not limited to the chassis distribution box 23, DC contactor 25 and chassis fuse box 26 installed.

[0059] In some embodiments, see Figure 2 , Figures 5 to 8 As shown, the upper pressure plate 5 is provided with multiple support plates 24 for installing different electrical components. The support plates 24 can maintain a certain gap between the installed electrical components and the upper pressure plate 5, which plays a certain role in heat dissipation of the electrical components and also avoids heat transfer between the battery 11 and the electrical components, thus affecting the sensitivity of the electrical components.

[0060] In this application, the chassis distribution box 23, DC contactor 25 and chassis fuse box 26 are respectively installed on different support bends 24, and they will not be in direct contact with each other, which reduces the mutual influence of heat between different components, ensures the flow capacity of hot air, and improves the heat dissipation effect of the electrical control box 1.

[0061] As is well known, temperature has a significant impact on the sensitivity and service life of electrical components. In the design structure of this application, the heat dissipation performance of electrical components and battery 11 is fully considered. By leaving gaps around battery 11 and gaps between electrical components and battery 11, the mutual influence of heat between different components is reduced, the heat dissipation effect of electrical control box 1 is improved, the failure of electrical components is reduced, and the sensitivity of electrical components is ensured.

[0062] In some embodiments, combined with Figure 7 and Figure 8 As shown, a rubber pad 4 is provided between the upper pressure plate 5 and the battery 11.

[0063] In the above technical solution, by setting a rubber pad 4 between the battery 11 and the upper pressure plate 5, the hard-hard contact between the battery 11 and the upper pressure plate 5 is converted into a soft-hard contact, avoiding the risk of damage to the battery 11 when the upper pressure plate 5 is pressed. At the same time, the rubber pad 4 also has the function of insulation and heat insulation between the battery 11 and the electrical components, which can avoid mutual interference between the battery 11 and the electrical components.

[0064] The rubber pad 4 mentioned above can be made of rubber with a thickness of 4-8 mm, for example, rubber pad 4 is 5 mm, 6 mm, 7 mm, etc.

[0065] In some embodiments, the second positioning structure is combined with Figure 2 , Figures 4 to 8 The understanding includes: the support block 16 fixed on the side plate, and the support plate 20 supported between the partition plate 15 and the base plate 18 of the electrical control box body 3; the controller is divided into a central controller 21 and a vehicle controller 17, the central controller 21 is installed on the support plate 20, and the vehicle controller 17 is installed on the support block 16.

[0066] The second positioning structure positions and supports the electrical components installed within the electrical component mounting cavity. In this application, the central controller 21 and the vehicle controller 17 are primarily installed together, and the status of the controllers within the cavity can be observed through the corresponding inspection windows on the side panel. By installing the controllers separately and creating gaps between them, mutual interference in heat and signals between the different controllers is reduced. Simultaneously, the reserved gaps also provide space for wiring.

[0067] Among them, the support plate 20, which is supported between the partition plate 15 and the bottom plate 18, also has the function of supporting the battery 11 and improving the overall strength of the electrical control box body 3.

[0068] Preferably, two support blocks 16 are provided on the side panel, and the vehicle controller 17 is fixed to the side panel by screws.

[0069] Optionally, multiple wiring bends 19 are also provided on the base plate 18 to provide structural support for the straightening and organization of the wire harness. For example, the wire harness can be constrained by passing it through the gap formed between the wiring bend 19 and the base plate 18.

[0070] In some embodiments, see Figures 6 to 8 As shown, the support plate 20 has flanges on both sides, and the upper and lower ends of the flanges are supported on the partition plate 15 and the base plate 18, respectively. The flanges provided on both sides of the support plate 20 can further enhance the support strength of the support plate 20.

[0071] After the electrical control box 1 is assembled, it needs to be installed on the vehicle. Therefore, the outer side of the electrical control box body 3 needs to be provided with an installation structure that facilitates fixing it to the vehicle body. The installation structure of this application is set as follows.

[0072] In some embodiments, see Figure 3 and Figure 4 As shown, a wing plate 10 for connecting to the vehicle body frame is provided on the outer side of the side plate. The wing plate 10 is provided with mounting holes, and the electrical control box 1 can be mounted on the vehicle by bolts.

[0073] Based on the same inventive concept, this application also provides an electric loader, including the aforementioned electrical control box 1; wherein, the electrical control box 1 is mounted on the rear frame 2 of the electric loader, see [link to relevant documentation]. Figure 1 As shown.

[0074] The electric loader provided in this application integrates electrical components and the battery 11 into a single electrical control box 1. In the event of an electrical fault, the control box 1 can be opened to inspect each component individually, making inspection convenient and enabling quick troubleshooting and timely repair. This reduces troubleshooting and repair time and avoids the time-consuming and labor-intensive problems caused by repairing different parts of the vehicle. Furthermore, the battery 11 is directly installed in the control box 1, making installation simple and convenient. In particular, integrating electrical components and the battery 11 into a single control box 1 reduces the space occupied within the vehicle and improves the utilization rate of the vehicle's interior space.

[0075] For example, the electrical control box 1 is installed in the space between the right side walkway and the rear frame 2 of the electric loader. The electrical control box 1 is hung on the side of the rear frame 2 via the wing plate 10. On the right side walkway, a plurality of support columns 9 are provided on the side plate of the electrical control box body 3. The center of the support column 9 is provided with a threaded hole. The electrical control box 1 is fastened between the right side walkway and the rear frame 2 by bolts connected to the support column 9.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
