Description

Technical Field

[0001] This utility model relates to the field of high-voltage equipment technology, and in particular to a high-voltage equipment and a new energy mining vehicle. Background Technology

[0002] New energy vehicles require various high-voltage devices to meet energy supply and propulsion needs. As vehicle integration demands increase, the arrangement of these devices becomes more compact. Current high-voltage wiring harness layouts lack fixed points at the high-voltage line exits, leading to a chaotic wiring arrangement. Furthermore, the complex high-voltage equipment areas experience significant wiring friction, resulting in insulation wear. This is particularly problematic in mining vehicles operating under complex conditions and experiencing substantial vibrations, where the risk of high-voltage wiring harness damage is high. During operation, disordered movement of the high-voltage wiring harness can easily cause insulation failure, potentially leading to uncontrollable consequences such as overall vehicle insulation failure.

[0003] Therefore, how to reduce the risk of damage to high-voltage wiring harnesses and improve the operational stability of new energy vehicles is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a high-voltage device to reduce the risk of damage to high-voltage wiring harnesses and improve the operational stability of new energy vehicles.

[0005] Another objective of this utility model is to provide a new energy mining vehicle that includes the aforementioned high-voltage equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-voltage device, comprising:

[0008] Equipment bracket, used to support and fix the high-voltage box, from which several high-voltage wire bundles are led out;

[0009] A number of the wire clips are fixedly mounted on the equipment bracket. The wire clips are elastic elements and have an open structure on the side facing away from the equipment bracket so that the high-voltage wire harness can be pressed in and clamped. The number of wire clips is not less than the number of high-voltage wire harnesses.

[0010] Preferably, in the above-mentioned high-voltage equipment, the high-voltage box is provided with a gland to connect the high-voltage wiring harness, and the gland and the wire clamp correspond one-to-one and are coaxially arranged.

[0011] Preferably, the high-voltage equipment further includes a mounting bracket, which is fixed to the equipment bracket and has a plurality of mounting holes, and one end of the line clamp is tapered and is inserted into and fixed in the mounting hole.

[0012] Preferably, in the above-mentioned high-voltage equipment, a preset number of mounting holes are provided on a single mounting bracket, and at least two mounting brackets can be fixed on a single equipment bracket.

[0013] Preferably, in the above-mentioned high-voltage equipment, a locking hole is provided at one end of the line clamp that is inserted into the mounting hole. The locking hole is a through hole structure for the insertion of a locking member of the bent structure. The locking member is inserted into the locking hole to limit and fix the line clamp to the mounting bracket.

[0014] Preferably, in the above-mentioned high-voltage equipment, a rubber gasket is fixedly provided in the area of ​​the line clamp used to contact the high-voltage wire harness.

[0015] Preferably, in the above-mentioned high-voltage equipment, the line clamps are spaced apart and stacked in a first direction, the first direction being the axial direction of the high-voltage wire harness, and a single high-voltage wire harness is connected to at least two line clamps in the first direction.

[0016] Preferably, in the above-mentioned high-voltage equipment, the mounting bracket is fixed to the equipment support by welding or bolting.

[0017] Preferably, in the above-mentioned high-voltage equipment, any two of the high-voltage wire harnesses are arranged in parallel.

[0019] As can be seen from the above technical solution, the high-voltage equipment provided by this utility model has wire clips installed on the equipment bracket used to support the high-voltage box, so as to add fixing points for the high-voltage wire harness near the outlet of the high-voltage box. The wire clips are elastic structures with openings, so that the high-voltage wire harness can be fixed in the wire clips by a convenient pressing action. The wire clips can be installed on the equipment bracket through an assembly connection structure, and the number can be increased or decreased. It is only necessary to ensure that the number of wire clips is not less than the number of high-voltage wire harnesses, so that each high-voltage wire harness has at least one fixing point.

[0026] The core of this utility model lies in disclosing a high-voltage device to reduce the risk of damage to high-voltage wiring harnesses and improve the operational stability of new energy vehicles.

[0027] Another core aspect of this utility model is to provide a new energy mining vehicle that includes the aforementioned high-voltage equipment.

[0028] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention as described in the claims.

[0029] like Figure 1-4As shown, the high-voltage equipment provided in this embodiment includes an equipment bracket 10 and wire clamps 40. The equipment bracket 10 is a rigid structure for connection with the vehicle body, providing a stable mounting plane or fixing structure for the high-voltage box 20. The high-voltage box 20 is fixedly mounted on the equipment bracket 10 and has several high-voltage wire harnesses 30 extending out to meet the electrical connection requirements of the high-voltage box 20. In addition, the equipment bracket 10 is also fixedly equipped with several wire clamps 40. The wire clamps 40 can be fixed using a detachable assembly structure, such as threads or snap-fit ​​buckles, to ensure that an appropriate number of wire clamps 40 are installed according to the number of high-voltage wire harnesses 30 extending from the high-voltage box 20. This avoids redundant wire clamps 40 affecting equipment installation or insufficient wire clamps 40 affecting use.

[0030] Specifically, the line clamp 40 is an elastic element with an opening, and its opening structure is located on the side facing away from the equipment bracket 10. The high-voltage wire can be inserted into the line clamp 40 by pressing it through the opening structure. At the same time, the line clamp 40 clamps the high-voltage wire bundle 30 through elasticity, thereby guiding and fixing the high-voltage wire bundle 30 outside the high-voltage box 20. The number of line clamps 40 can be equal to or greater than the number of high-voltage wire bundles 30, and each high-voltage wire bundle 30 has at least one corresponding line clamp 40 for limiting.

[0031] The high-voltage equipment provided in this embodiment of the utility model has wire clips 40 installed on the equipment bracket 10 for supporting the high-voltage box 20, so as to add fixing points for the high-voltage wire harness 30 near the outlet of the high-voltage box 20. The wire clips 40 are elastic structures with openings, so that the high-voltage wire harness 30 can be fixed in the wire clips 40 by a convenient pressing action. The wire clips 40 can be installed on the equipment bracket 10 through an assembly connection structure, and the number can be increased or decreased, as long as the number of wire clips 40 is not less than the number of high-voltage wire harnesses 30, so that each high-voltage wire harness 30 has at least one fixing point. The above structure provides convenient fixing points for the high-voltage wire harness 30, making the structure of the high-voltage equipment compact and regular, and effectively avoiding safety problems such as wire harness wear and insulation failure caused by vehicle vibration during driving.

[0032] Furthermore, in the high-voltage equipment provided in this embodiment of the present invention, a gland is provided on the high-voltage box 20 to connect the high-voltage cable harness 30. The gland can lock the cable, thereby preventing axial displacement or radial rotation of the cable when it exits from the high-voltage box 20. At the same time, the gland and the clamp 40 correspond one-to-one and are coaxially arranged. It should be noted that the one-to-one correspondence here specifically means that the number of glands and clamps 40 is equal, and the high-voltage cable harness 30 led out from a single gland position is fixed by only one clamp 40.

[0033] The coaxial arrangement of the gland and wire clamp 40 allows the high-voltage wire harness 30 to exit along the axial direction of the gland and wire clamp 40, preventing the wire harness from bending. When multiple glands are arranged in parallel, any two high-voltage wire harnesses 30 can remain parallel, making the arrangement of the high-voltage wire harness 30 more regular and avoiding the stress caused by wire harness bending. This prevents the high-voltage wire harness 30 from being subjected to lateral stress at the exit point, which could cause gaps and damage to waterproofing and dustproofing.

[0034] To improve the assembly efficiency of high-voltage equipment, in some embodiments of this utility model, the high-voltage equipment further includes a mounting bracket 50, which is fixedly connected to the equipment bracket 10. The mounting bracket 50 has several mounting holes 510, and one end of the line clip 40 is tapered and can be inserted into the mounting hole 510 to fix the line clip 40 on the mounting bracket 50. In this structure, the line clip 40 can be pre-installed with the mounting bracket 50 offline to form an integrated structure with multiple line clips 40 on a single mounting bracket 50. When it is necessary to install the line clip 40, the mounting bracket 50 is fixedly connected to the equipment bracket 10 to complete the installation of the line clip 40.

[0035] Based on the above embodiments, in order to improve the modular assembly effect of the line card 40, it is preferable that a single mounting bracket 50 can be provided with a preset number of mounting holes 510. It should be noted that the preset number is set by the operator according to the number of high-voltage wire harnesses 30 commonly used in high-voltage equipment. Preferably, the number of mounting holes 510 provided on a single mounting bracket 50 is half the number of high-voltage wire harnesses 30. At the same time, at least two mounting brackets 50 can be fixed on a single equipment bracket 10. The modular structure of the mounting brackets 50 is easy to store, transport and assemble, and can be set in the concentrated area of ​​the high-voltage wire harnesses 30 to reduce the material usage of the mounting brackets 50.

[0036] Furthermore, in some embodiments of this utility model, in order to improve the installation stability of the wire clip 40 and thus increase the fixing effect of the high-voltage wire harness 30, the wire clip 40 is also provided with a locking hole 410 at one end of its insertion into the mounting hole 510. The locking hole 410 is a through hole structure and cooperates with a locking member. The locking member is set as a bent structure so that it can be inserted into the locking hole 410 after the locking hole 410 passes through the mounting hole 510, so that the locking hole 410 cannot be dislodged from the mounting hole 510, thereby improving the locking effect of the wire clip 40 on the high-voltage wire harness 30 under vehicle operating conditions.

[0037] Furthermore, to prevent damage to the outer structure of the high-voltage wire harness 30 caused by the snap-fit ​​between the wire clip 40 and the high-voltage wire harness 30, it is preferable that a rubber pad is fixedly provided on the annular area of ​​the wire clip 40 for contacting the high-voltage wire harness 30, so as to provide flexible protection for the high-voltage wire harness 30 when snapping it in a flexible contact manner.

[0038] In some embodiments of this utility model, the wire clips 40 are spaced apart and stacked in the first direction. It should be noted that the first direction and the axial direction of the high-voltage wire harness 30 are also the extension direction of the high-voltage wire harness 30 after it is led out of the high-voltage box 20. At the same time, each high-voltage wire harness 30 is connected to at least two wire clips 40 in the first direction. In a long area after the high-voltage wire harness 30 is led out of the high-voltage box 20, it can be locked in position through at least two fixed points, thereby improving the stability of the high-voltage wire harness 30.

[0039] Furthermore, it should be noted that the mounting bracket 50 can be fixed to the equipment bracket 10 by welding or bolting. Welding provides better integration between the mounting bracket 50 and the support bracket, thus improving the stability of the mounting bracket 50 during vehicle operation. Bolting, on the other hand, facilitates easy assembly, inspection, and replacement when convenient assembly of the mounting bracket 50 is required.

[0040] Furthermore, when multiple high-voltage wire harnesses 30 are led out from the high-voltage box 20, any two high-voltage wire harnesses 30 are arranged in parallel to reduce the risk of damage during assembly.

[0041] Furthermore, this utility model embodiment also provides a new energy mining vehicle, which is equipped with the high-voltage equipment provided in any of the above embodiments to improve the stability of its high-voltage wiring harness 30.
