Description

Technical Field

[0001] The utility model relates to the technical field of tractor accessories, in particular to a novel tractor high-voltage box. Background Art

[0002] The tractor high-voltage box is a device designed for tractors. Its main function is to provide high-voltage power to drive the tractor's power system. It is usually installed in the engine compartment of the tractor and connected to the tractor's engine through a high-voltage cable. The tractor high-voltage box is composed of multiple high-voltage batteries. Each battery has a high voltage and capacity, which can provide enough energy to drive the tractor's motor and electrical equipment. After these batteries are combined in series and parallel, they can output high voltage electricity of up to several thousand volts, providing strong power for the tractor's power system. The tractor high-voltage box is an important part of the tractor, providing efficient and reliable power support for the tractor's power system, ensuring the normal operation and safe transportation of the vehicle.

[0003] The high-voltage box of the tractor is generally arranged on both sides of the vehicle. The original layout: the high and low voltage plug-ins are arranged on adjacent surfaces, then at least the side with the plug-in needs to face outward (towards the inside, that is, the side of the beam, and there is no way to perform maintenance later). Since the wiring of the plug-in requires wiring space, and the high-voltage box is arranged in the warehouse, it needs to be closed with a sealing plate, which requires reserving wiring space. The plug-in cannot be too close to the sealing plate, which causes the high-voltage box to be arranged inside (that is, in the direction of the beam), which is not conducive to wiring, causing unnecessary trouble for later maintenance, and causing unnecessary waste of space.

[0004] Therefore, it is necessary to provide a novel tractor high-voltage box to solve the above-mentioned technical problems. Utility Model Content

[0005] The utility model aims to provide a novel high-voltage box for a tractor vehicle, so as to solve the problem in the prior art that the high-voltage and low-voltage plug-ins of the high-voltage box of the tractor vehicle are arranged on adjacent surfaces, which is not conducive to wiring, causes unnecessary troubles for later maintenance, and causes unnecessary waste of space.

[0006] To achieve the above-mentioned purpose, the utility model solves the above-mentioned technical problems as follows: a new type of tractor high-voltage box, including a high-voltage box body, two opposite side surfaces of the high-voltage box body are respectively set as A surface and C surface, and the side surface adjacent to the A surface and the C surface of the high-voltage box body is set as B surface, and a plurality of high and low pressure plug-ins are arranged on the high-voltage box body and the plurality of high and low pressure plug-ins are distributed on the A surface and the C surface.

[0007] As a further scheme of the utility model, the A surface is provided with battery positive 1, battery positive 2, battery negative 1, battery negative 2 and heating, and the C surface is provided with output positive 1, charging positive, output positive 2, output negative 1, charging negative, output negative 2, low-voltage communication, whole vehicle communication, detection port and air-conditioning liquid cooling.

[0009] As a further solution of the utility model, a maintenance switch is provided on the side of the A surface.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: multiple high and low voltage plug-ins on the high voltage box body are arranged on opposite surfaces (surface A and surface C), and by changing the arrangement of the high and low voltage plug-ins, the high voltage wiring harness is changed from single-side outlet to double-side outlet; and the distribution arrangement of high voltage wiring harness plug-ins in different directions is realized. (For example: the high-voltage box-battery high-voltage plug-in is arranged on the A side, and the high-voltage box-all-in-one high-voltage plug-in is arranged on the C side), saving the wiring space reserved for the cover plate, facilitating layout, saving box layout space, facilitating the installation of the high-voltage wire harness, and optimizing the wiring method. It can effectively improve the convenience of the high-voltage box layout and the rationality of the wiring harness direction, and provide the convenience and safety of the vehicle layout; the output positive one, output positive two, output negative one, and output negative two are arranged on the A side, and the battery positive one, battery negative one, battery positive two, and battery negative two are arranged on the C side.

[0018] The present invention will be further described below in conjunction with the embodiments.

[0019] See also Figure 1-4 The utility model provides a new type of tractor high-voltage box, including a high-voltage box body 2, two opposite side surfaces of the high-voltage box body 2 are respectively set as A surface 18 and C surface 19, and the side surface adjacent to the A surface 18 and the C surface 19 of the high-voltage box body 2 is set as B surface. A plurality of high and low voltage plug-ins are arranged on the high-voltage box body 2 and the plurality of high and low voltage plug-ins are distributed on the A surface 18 and the C surface 19; the plurality of high and low voltage plug-ins on the high-voltage box body 2 are arranged on opposite surfaces (A surface 18 and C surface 19), and by changing the arrangement of the high and low voltage plug-ins, the high-voltage wiring harness is changed from single-side outlet to double-side outlet; and the distribution arrangement of high-voltage wiring harness plug-ins with different directions is realized. (For example: the high-voltage box-battery high-voltage plug-in is arranged on the A side 18, and the high-voltage box-all-in-one high-voltage plug-in is arranged on the C side 19), saving the wiring space reserved for the cover plate, facilitating layout, saving box layout space, facilitating the installation of high-voltage wire harnesses, and optimizing the wiring method. It can effectively improve the convenience of high-voltage box layout and the rationality of wire harness direction, and provide layout convenience and safety for the entire vehicle.

[0020] Further as Figure 2 and Figure 3As shown, it is worth specifying that the A surface 18 is provided with a battery positive one 3, a battery positive two 4, a battery negative one 6, a battery negative two 7 and a heater 16, and the C surface 19 is provided with an output positive one 5, a charging positive 8, an output positive two 9, an output negative one 10, a charging negative 11, an output negative two 12, a low-voltage communication 13, a vehicle communication 14, a detection port 15 and an air-conditioning liquid cooling 17; the output positive one 5, the output positive two 9, the output negative one 10, and the output negative two 12 are all high-voltage box outputs to the multi-in-one high-voltage plug-in, and the battery positive one 3, the battery negative one 6, the battery positive two 4, and the battery negative two 7 are all power batteries to high voltage The high-voltage plug-ins of the box were originally arranged on the same panel. Due to the arrangement of the high-voltage box, the arrangement of the plug-ins on adjacent surfaces would make the high-voltage plug-ins connected to the power battery and the all-in-one too compact, and not conducive to the routing of the all-in-one or the power battery, resulting in unnecessary waste of wiring harnesses; the output positive one 5, output positive two 9, output negative one 10, and output negative two 12 are arranged on the A surface 18, and the battery positive one 3, battery negative one 6, battery positive two 4, and battery negative two 7 are arranged on the C surface 19, so that the wires can be output on both sides of the high-voltage box, the routing path is optimized, and the routing method of the high-voltage wiring harness is greatly improved.

[0021] Further as Figure 3 As shown, it is worth specifying that the battery positive 1 3 and the battery negative 1 6 on the A side 18 are adjacent, and the battery positive 2 4 and the battery negative 2 7 are adjacent; the original high-voltage box high-voltage plug-in battery positive 1 3 and the battery positive 2 4 are adjacent, and the battery negative 1 6 and the battery negative 2 7 are adjacent. Since the battery positive 1 3 and the battery positive 2 4 are both positive electrodes, and the battery negative 1 6 and the battery negative 2 7 are both negative electrodes, it is easy for the battery positive 1 3 and the battery positive 2 4 to be misconnected, and the same is true for the battery negative 1 6 and the battery negative 2 7; after optimization, the battery positive 1 3 and the battery negative 1 6 are adjacent, and the battery positive 2 4 and the battery negative 2 7 are adjacent, to prevent misconnection during workshop operation.

[0022] Further as Figure 3 As shown, it is worth explaining in detail that a maintenance switch 1 is arranged on the side of the A surface 18; the two original maintenance switches of the high-voltage box are merged into a maintenance switch 1 of higher specifications, which saves the layout space of the panel and can reduce the length of the A surface 18 and the width of the B surface.

[0023] In summary: the multiple high and low voltage plug-ins on the high voltage box body 2 are arranged on opposite surfaces (on the A surface 18 and the C surface 19). By changing the arrangement of the high and low voltage plug-ins, the high voltage wiring harness is changed from single-side outlet to double-side outlet; the distribution arrangement of high voltage wiring harness plug-ins in different directions is realized. (For example: the high-voltage plug-in of the high-voltage box-battery is arranged on the A side 18, and the high-voltage box-all-in-one high-voltage plug-in is arranged on the C side 19), saving the wiring space reserved by the cover plate, facilitating layout, saving box layout space, facilitating the installation of the high-voltage wire harness, optimizing the wiring method, and effectively improving the convenience of the high-voltage box layout and the rationality of the wiring harness direction, providing the layout convenience and safety of the whole vehicle, and arranging the output positive one 5, output positive two 9, output negative one 10, and output negative two 12 on the A side 18, and the battery positive one 3, battery negative one 6, battery positive two 4, and battery negative two 7 on the C side 19. The wires can be connected on both sides of the high-voltage box to optimize the wiring path, which greatly improves the wiring method of the high-voltage wire harness. After optimization, the battery positive one 3 and the battery negative one 6 are adjacent, and the battery positive two 4 and the battery negative two 7 are adjacent to prevent misplugging during workshop operation, and the original two maintenance switches of the high-voltage box are merged into a high-specification maintenance switch 1, which saves the layout space of the panel and can reduce the length of the A side 18 and the width of the B side.
