[0034] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0035] As Figure 1 、 Figure 2 shown, a new energy mining vehicle distribution box support assembly includes a high-voltage box support 201, a plurality of fixing members 202, a plurality of wire harness supports 204, and a porous wire clamp 205 used in cooperation therewith; the high-voltage box support 201 is used for assembling a high-voltage distribution box 207, the high-voltage box support 201 is arranged on the top surface of the frame gantry beam 203, and the width of the high-voltage box support 201 is greater than the width of the frame gantry beam 203, providing a storage space for the wire harness extending from the high-voltage distribution box 207; a plurality of fixing members 202 are respectively arranged on the front and rear side surfaces of the frame gantry beam 203 for fixing the high-voltage box support 201 on the frame gantry beam 203; a plurality of wire harness supports 204 and the porous wire clamp 205 used in cooperation therewith are respectively arranged on the front and rear side surfaces of the high-voltage box support 201 to fix and store the wire harness extending from the high-voltage distribution box 207, improving the space utilization rate and reducing the maintenance and installation costs at the same time.

[0036] The above high-voltage box support will be further described below.

[0037] As Figure 1 、 Figure 2As shown, the high-voltage box bracket 201 is a U-shaped frame formed by welding two cross beams and two longitudinal beams. The two cross beams are overlapped on the frame gantry beam 203, and the two longitudinal beams are respectively located at the front upper and rear upper parts of the frame gantry beam 203; multiple mounting holes are provided on the cross beams and longitudinal beams.

[0038] A further solution is that during the actual operation of the mine car, due to the vibration and impact generated during the operation, the high-voltage box bracket 201 faces a huge risk of breaking, so a reinforcing beam 206 is added to the center of the high-voltage box bracket 201, and the reinforcing beam 206 does not directly contact the frame gantry beam 203, but only serves to reinforce the high-voltage box bracket 201 to prevent the vibration from being transmitted to the high-voltage distribution box 207. Figure 3 As shown, after adding a reinforcing crossbeam 206, the high-voltage box bracket 201 forms a Japanese-shaped frame.

[0039] Continue to refer to Figure 3 As shown, a fixing piece 202 is installed at each end of each crossbeam, and the high-voltage box bracket 201 is fixed to the frame gantry beam 203 through two fixing pieces 202 on the front and rear sides of the frame gantry beam 203; the two ends of the wiring harness bracket 204 on the front side of the frame gantry beam 203 and below the high-voltage box bracket 201 are respectively connected to the two fixing pieces 202 on the front side of the frame gantry beam 203; the two ends of the wiring harness bracket 204 on the rear side of the frame gantry beam 203 and below the high-voltage box bracket 201 are respectively connected to the two fixing pieces 202 on the rear side of the frame gantry beam 203.

[0040] The above-mentioned fixing member is further described below.

[0041] like Figure 4 As shown, the fixing member 202 is composed of a right-angle bent plate and a support plate fixed to the inner side of the right-angle bent plate; the top plate of the right-angle bent plate is provided with at least one mounting hole, which is fixed to the crossbeam by bolts and nuts; the side plate of the right-angle bent plate is provided with at least one mounting hole, which is fixed to the threaded seat on the side of the frame gantry beam 203 by bolts; the support plate is provided with at least one mounting hole, which is fixed to the wire harness bracket 204 by bolts and nuts. The high-voltage box bracket 201 is fixed to the side of the frame gantry beam 203 by the fixing member 202, which reduces the overall height and improves the space utilization.

[0042] The above-mentioned wire harness bracket and multi-hole wire clamp are further described below.

[0043] like Figure 5As shown in the figure, the wire harness bracket 204 includes a cross bar and two side plates. Each end of the cross bar is provided with a first mounting hole, and a plurality of second mounting holes are provided between the two first mounting holes; the two side plates are respectively located at both ends of the cross bar. One end of the side plate is connected to the end of the cross bar through bolts and nuts, and the other end of the side plate is connected to the fixing member through bolts and nuts.

[0044] As Figure 5 shown in the figure, the multi-hole wire clamp 205 is provided with a plurality of third mounting holes corresponding to the second mounting holes one by one. The multi-hole wire clamp 205 is fixed on the cross bar through a plurality of bolts and nuts; a plurality of arc-shaped grooves for clamping the wire harness are arranged at intervals on the side surface of the multi-hole wire clamp 205 facing the cross bar.

[0045] In a further solution, when wire harnesses extend from the left and right side surfaces of the high-voltage distribution box 207, the multi-hole wire clamps are installed on the side plates.

[0046] In a further solution, as Figure 1 、 Figure 2 shown in the figure, a plurality of double shock pads 208 are arranged between the high-voltage distribution box 207 and the high-voltage box bracket 201.

[0047] In summary, the high-voltage box bracket is connected to the side surface of the vehicle frame gantry beam through the fixing member using bolts. The vehicle frame gantry beam is a part of the whole vehicle frame, and its strength is much higher than that of the traditional bracket, which improves the strength of the high-voltage box bracket assembly. At the same time, the width of the vehicle frame gantry beam is smaller than that of the high-voltage box bracket, providing a storage space for the numerous wire harnesses extending from the high-voltage distribution box, increasing the connection between the wire harness bracket and the fixing member. The wire harness bracket and the multi-hole wire clamp together fix and store the high-voltage box wire harness, improving the space utilization rate and reducing the maintenance and installation costs.

[0048] During the actual operation of the mine car, due to the vibrations and impacts generated during the operation, the high-voltage box bracket faces a huge risk of fracture. Therefore, a reinforcing cross beam is added in the center of the high-voltage box bracket, and the reinforcing cross beam does not directly contact the vehicle frame gantry beam, but only serves to reinforce the high-voltage box bracket frame to prevent the vibrations from being transmitted to the high-voltage distribution box.

[0049] The structure of the high-voltage distribution box bracket assembly proposed by the present utility model optimizes the layout compared with the existing structure. The high-voltage box bracket is integrated into the side of the vehicle frame, improving its structural strength, optimizing the space utilization rate, providing a space for accommodating the high-voltage wire harness, and integrating the wire harness bracket on the bracket to store the high-voltage wire harness, making the wire harness planning more reasonable and reducing the difficulty of wire harness assembly and fixing and the maintenance difficulty.

[0050] The present utility model also provides a new energy mine car, including a vehicle frame gantry beam and a high-voltage distribution box. The above-mentioned new energy mine car distribution box bracket assembly is installed on the vehicle frame gantry beam, and the high-voltage distribution box is installed on the new energy mine car distribution box bracket assembly.
