[0002] The newly developed 300kW high-power range extender uses a high-power generator with a large generator controller. However, the range extender has a compact layout and strict space constraints. Therefore, it is crucial to find a reasonable place for the large generator controller without increasing the overall size of the range extender.

[0003] Current generator controllers are typically mounted on top of the generator using brackets or routed via long cables to a compartment outside the range extender. This arrangement significantly increases the size of the range extender, hindering a compact overall design. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a range extender support leg with mounting holes for a high-power generator controller, which aims to solve the problem that the overall space arrangement of the range extender is not compact after the high-power generator controller is installed.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A range extender support leg with mounting holes for a high-power generator controller includes a controller mounting plate for mounting the generator controller, a fastening back plate fixedly connected to the generator, two transverse plates symmetrically arranged between the lower parts of the controller mounting plate and the fastening back plate, four support reinforcing ribs arranged at the bottom of the transverse plates and forming two supports at the lower part of the fastening back plate, and two base plates respectively arranged between the four support reinforcing ribs; a back plate reinforcing rib is provided between the controller mounting plate, the fastening back plate and the transverse plates; the controller mounting plate is a rectangular frame with an open center; the fastening back plate is an H-shaped frame structure; the upper end of the fastening back plate is inserted into the upper end of the controller mounting plate and welded for fixation.

[0007] A further improvement of the technical solution of the present invention is that: a second bolt through hole is provided at each of the four corners of the controller mounting plate; a horizontal insertion hole for fastening the back plate is provided on each of the upper left and right sides of the controller mounting plate; and a vertical insertion hole for fastening the back plate is also provided on each of the upper left and right sides of the controller mounting plate.

[0008] A further improvement of the technical solution of the present invention is that: the upper end and the left and right sides of the upper part of the fastening back plate are provided with bends that can be inserted into the controller mounting plate.

[0009] A further improvement of the technical solution of the present invention is that: four first bolt through holes are provided on each side of the middle part of the fastening back plate, and the four first bolt through holes are respectively provided on both sides of the back plate reinforcing rib.

[0010] A further improvement of the technical solution of the present invention is that a third bolt through hole is provided on the base plate.

[0011] A further improvement of the technical solution of the present invention is that: an elastic support block is provided under the base plate, and a fixing plate is provided under the elastic support block.

[0012] A further improvement of the technical solution of the present invention is that the controller mounting plate is made of low carbon steel plate and formed by laser cutting.

[0013] A further improvement of the technical solution of the present invention is that the fastening back plate is formed by laser cutting and sheet metal bending.

[0014] A further improvement to the technical solution of the present invention is that the width of the transverse plate must avoid the head of the fastening bolt passing through the first bolt hole.

[0015] A further improvement of the technical solution of the present invention is that: when the fastening back plate is inserted into the controller mounting plate, it must not extend beyond the surface of the controller mounting plate, and welding is performed on the back side of the controller mounting plate.

[0016] The technological advancements achieved by this invention due to the adoption of the above technical solutions are as follows:

[0017] 1. This invention reduces the space requirement of the 300kW range extender by setting a support leg on one side of the generator that can install the generator controller and be fixedly connected to the generator, thereby improving the compactness of the overall structure. It solves the problem of loose layout and large space required in the existing technology of mounting the generator controller on the top of the bracket or arranging the generator controller outside the range extender cabin.

[0018] 2. This invention cleverly arranges a large generator controller while ensuring the support of the entire range extender, reducing the space requirements of the entire range extender and making it more compact. It also reduces the length of the high-voltage transmission cable, making it more energy-efficient and economical. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0027] like Figure 1 As shown, a range extender support leg with mounting holes for a high-power generator controller includes a controller mounting plate 21 for mounting the generator controller, a fastening back plate 22 fixedly connected to the generator 1, two transverse plates 28 symmetrically arranged between the lower parts of the controller mounting plate 21 and the fastening back plate 22, four support reinforcing ribs 210 arranged at the bottom of the transverse plates 28 and the lower part of the fastening back plate 22 to form two supports, and two base plates respectively arranged between the four support reinforcing ribs 210; a back plate reinforcing rib 27 is provided between the controller mounting plate 21, the fastening back plate 22 and the transverse plates 28; the controller mounting plate 21 is a rectangular frame with an open middle; the fastening back plate 22 is an H-shaped frame structure; the upper end of the fastening back plate 22 is inserted into the upper end of the controller mounting plate 21 and welded to fix it.

[0028] Furthermore, a second bolt through hole 25 is provided at each of the four corners of the controller mounting plate 21; a horizontal insertion hole 24 for fastening the back plate is provided on each of the upper left and right sides of the controller mounting plate 21; and a vertical insertion hole 26 for fastening the back plate is also provided on each of the upper left and right sides of the controller mounting plate 21.

[0029] Furthermore, the upper end and both sides of the upper part of the fastening back plate 22 are provided with bends that can be inserted into the controller mounting plate 21.

[0030] Furthermore, four first bolt through holes 23 are provided on each side of the middle part of the back plate 22, and the four first bolt through holes 23 are respectively provided on both sides of the back plate reinforcing rib 27.

[0031] Furthermore, a third bolt through hole 29 is provided on the base plate.

[0032] Furthermore, an elastic support block 3 is provided under the base plate, and a fixing plate is provided under the elastic support block 3.

[0033] Furthermore, the controller mounting plate 21 is made of low-carbon steel plate and is laser-cut.

[0034] Furthermore, the fastening backplate 22 is formed by laser cutting and sheet metal bending.

[0035] Furthermore, the width of the transverse plate 28 must avoid the head of the fastening bolt passing through the first bolt hole 23.

[0036] Furthermore, when the backplate 22 is inserted into the controller mounting plate 21, it must not extend beyond the surface of the controller mounting plate 21, and welding should be performed on the back of the controller mounting plate 22.

[0037] Specifically, such as Figure 1-2As shown, the controller mounting plate 21 is made of low-carbon steel plate and is formed by laser cutting; the fastening back plate 22 is the fastening mounting plate for the generator 1 and the support leg 2, and is formed by laser cutting and sheet metal bending; the first bolt through hole 23 is the bolt through hole for fastening the fastening back plate 22 to the generator; the transverse insertion hole 24 of the fastening back plate indicates that, in order to enhance the reliability of the welding part, the fastening back plate 22 is bent and inserted into the controller mounting plate 21, and must not exceed the surface of the controller mounting plate 21 to avoid affecting the installation of the larger generator controller. Welding is performed on the back of the controller mounting plate 21 to ensure that the welded part between the controller mounting plate 21 and the fastening back plate 22 is securely fastened; the second bolt through hole 25 is the bolt through hole for fastening the controller to the controller mounting plate 21. The back of the controller mounting plate 21 is designed with welding nuts, the controller is close to the controller mounting plate 21, and is fastened to a 4-bolt connection.

By combining vertical and horizontal methods, the fastening reliability of the connection between the controller mounting plate 21 and the fastening backplate 22 is further ensured. The backplate reinforcing ribs 27 are symmetrically arranged on the left and right sides to ensure that the structural strength and rigidity of the support leg 1 meet the actual engineering requirements. The width of the horizontal plate 28 is designed to avoid the head of the fastening bolt passing through the first bolt through hole 23. In order to reduce the torque of the controller on the bolt passing through the first bolt through hole 23, the width of the horizontal plate 28 should be reduced as much as possible to reduce the lever arm. The third bolt through hole 29 is the fastening bolt through hole for the bracket and the elastic support block 3. It is used for the fastening connection between the bracket and the elastic support block 3. Two bracket reinforcing ribs 10 are arranged on the left and right sides of the bracket to strengthen the support performance of the bracket, improve the bracket's resistance to deformation and damage, and increase the reliability of the bracket.
