[0033] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Embodiment 1

[0035] See also Figure 1 - Figure 8 , a motor controller housing for new energy vehicles, comprising: a mounting shell 1 and a cover 2 arranged above the mounting shell 1;

[0036] Four square grooves are symmetrically arranged on both sides of the inner wall of the cover 2;

[0037] Four fixed shells 3 are symmetrically fixedly mounted on the bottom of the cover 2, and the four fixed shells 3 are arranged in a rectangular shape;

[0038] A round rod 4 fixedly mounted on the inner wall of the fixed shell 3;

[0039] A clamping member 5 is disposed on the outer wall of the round rod 4, and a protruding portion of the clamping member 5 is clamped with a matching square groove, so as to fix the cover 2 and the mounting shell 1 together;

[0040] A spring 6 is fixedly mounted on one side of the inner wall of the fixed shell 3, and the other end of the spring 6 is connected to the clamping member 5;

[0041] A push rod 7 is fixedly mounted on one side of the clamping member 5 , and the other end of the push rod 7 extends to the outside of the cover 2 .

[0042] When the cam 2 is in the state of being disassembled, the push rod 7 is manually pressed in the direction of the sealing cover 2, so that the push rod 7 pushes the clamping piece 5 on the round rod 4 to slide toward the inner side of the fixed shell 3, and the protruding part of the clamping piece 5 is moved out of the square groove, and then the sealing cover 2 is moved upward to separate the mounting shell 1 from the sealing cover 2. On the contrary, when installing, the push rod 7 is manually pressed in the direction of the sealing cover 2, so that the push rod 7 pushes the clamping piece 5 on the round rod 4 and slides toward the inner side of the fixed shell 3, and then the sealing cover 2 is manually covered on the mounting shell 1, and then, the push rod 7 is manually released, and the squeezed spring 6 is reset while pushing the clamping piece 5 on the round rod 4, and the protruding part of the clamping piece 5 is clamped with the square groove, so that the sealing cover 2 can be stably fixedly connected with the mounting shell 1 without screws, thereby making the disassembly process between the mounting shell 1 and the sealing cover 2 very convenient, and there is no need to use tools such as screwdrivers, thereby avoiding defects such as screw stripping and loosening.

[0043] Furthermore, connecting plates 8 are provided on both sides of the cover 2, and the four push rods 7 are fixedly connected in pairs between the two connecting plates 8.

[0044] Specifically, through the connecting plates 8 on both sides of the cover 2, it enables a person to simultaneously press the four push rods 7 to slide.

[0045] Embodiment 2

[0046] Based on Embodiment 1, in this embodiment: positioning members 9 are provided in the grooves at the four outer corners of the installation shell 1. A first hollow tube 10 is fixedly installed at the bottom of the positioning member 9, and the first hollow tube 10 is inserted into the insertion hole on the installation shell 1. A second hollow tube 11 is fixedly installed at the top of the positioning member 9. A positioning groove 12 is formed on the cover 2, and the second hollow tube 11 is inserted into the positioning groove 12. A fixing component 13 is inserted into the cavity of the second hollow tube 11 and is used to fixedly connect the cover 2 and the installation shell 1.

[0047] The technical solution provided in this embodiment is: by manually inserting the first hollow tube 10 on the positioning member 9 into the insertion hole on the installation shell 1, the positioning member 9 can be connected to the installation shell 1. Then, when a person covers the cover 2 on the installation shell 1, the second hollow tube 11 is inserted into the positioning groove 12, which facilitates the preliminary fixing and limiting of the cover 2, and further enables the clamping member 5 to accurately and quickly insert into the square groove. After that, the fixing component 13 is inserted into the cavity of the second hollow tube 11, which can further improve the fixing effect between the installation shell 1 and the cover 2.

[0048] Furthermore, sealing rings 14 are sleeved on the outer side walls of the first hollow tube 10 and the second hollow tube 11.

[0049] Specifically, through the sealing rings 14, it is beneficial to ensure the sealing performance between the installation shell 1 and the cover 2.

[0050] Furthermore, the insertion hole on the installation shell 1 is T-shaped, the positioning groove 12 is ┴-shaped, and the sealing rings 14 on the first hollow tube 10 and the second hollow tube 11 are respectively located inside the T-shaped insertion hole and the ┴-shaped positioning groove 12.

[0051] Specifically, through the T-shaped and ┴-shaped designs, when the sealing rings 14 are located in the insertion hole and the positioning groove 12, they will neither affect the sealing effect nor prevent the two sides of the positioning member 9 from closely contacting the installation shell 1 and the cover 2, and thus can ensure an aesthetic appearance.

[0052] Furthermore, the fixing component 13 includes an inverted T-shaped rod 1301 inserted into the cavity of the second hollow tube 11. A limiting disk 1302 is fixedly installed at the top of the inverted T-shaped rod 1301, and a threaded rubber sleeve 1303 is sleeved on the outer side wall of the limiting disk 1302.

[0053] Specifically, the inverted T-rod 1301 is manually inserted into the cavity of the second hollow tube 11. During the insertion, under the action of the threaded rubber sleeve 1303, the friction between the inverted T-rod 1301 and the second hollow tube 11 can be increased, and the stability of the inverted T-rod 1301 can be ensured, so that the inverted T-rod 1301 is not easy to slip out of the cavity of the second hollow tube 11, and the inverted T-rod 1301 can be tightly and stably inserted into the cavity of the second hollow tube 11, and then the inserted inverted T-rod 1301 can block the cover 2 on the mounting shell 1 under the action of the limit plate 1302, thereby further improving the fixing effect between the mounting shell 1 and the cover 2.

[0054] It should be further explained that the inverted T-bar 1301 is composed of two bars of different thicknesses, and the limiting plate 1302 is fixedly mounted on the thin bar of the inverted T-bar 1301 , and the threaded rubber sleeve 1303 is sleeved on the thin bar of the inverted T-bar 1301 .

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
