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.

[0051] In the motor controller system, the busbar copper busbar connects the high-voltage input connector and the busbar. Before the filter component is set up separately, the power distribution and fuse also need to be set up separately before the filter component. The space utilization rate is low and the number of parts is large, resulting in high cost of the motor controller.

[0052] Based on the above problems, the utility model proposes a fuse assembly, a motor controller and a vehicle, aiming to reduce the number of parts and thus reduce the cost of the motor controller.

[0053] See also Figure 1 , Figure 2 In one embodiment of the utility model, the fuse assembly 100 includes a bracket 10, a busbar copper bar 20, a distribution cable 30 and a fuse 40; the busbar copper bar 20 is integrated in the bracket 10, and includes a copper bar positive electrode 21 and a copper bar negative electrode 22; the distribution cable 30 is integrated in the bracket 10, and includes a cable positive electrode 31 and a cable negative electrode 32, the cable positive electrode 31 is connected to the copper bar positive electrode 21, and the cable negative electrode 32 is connected to the copper bar negative electrode 22; the fuse 40 is integrated in the bracket 10, and connected to the copper bar positive electrode 21.

[0054] The technical solution of the present invention integrates the busbar copper bar 20, the distribution cable 30 and the fuse 40 on the same bracket 10, thereby effectively improving the space utilization, reducing the number of parts, and thus effectively reducing the cost of the motor controller.

[0055] As some examples, the positive electrode 31 of the cable can be connected to the positive electrode 21 of the copper busbar by using a rivet nut 50, and the negative electrode 32 of the cable can also be connected to the negative electrode 22 of the copper busbar by using a rivet nut 50; similarly, the fuse 40 can also be connected to the positive electrode 21 of the copper busbar by using a rivet nut 50.

[0056] As some examples, the bracket 10 may be provided with one or at least two insert nuts 60, so as to connect the fuse assembly 100 to the housing through the insert nuts 60, so as to ensure the installation reliability of the fuse assembly 100. It should be noted that when at least two insert nuts 60 are provided on the bracket 10, the distribution of the at least two insert nuts 60 is not specifically limited, as long as the busbar copper bar 20, the distribution cable 30 and the fuse 40 are avoided.

[0057] As some exemplary embodiments, the bracket 10 may be a plastic part, and the material cost is relatively low.

[0058] In actual application, the busbar copper bar 20 can be integrated on the first surface 11 of the bracket 10, or on the second surface 12 of the bracket 10, or at least partially embedded in the bracket 10. Similarly, the distribution cable 30 and the fuse 40 can be integrated on the first surface 11 of the bracket 10, or on the second surface 12 of the bracket 10, or at least partially embedded in the bracket 10.

[0059] In actual application, the fuse 40 can be directly connected to the copper busbar positive electrode 21 , or an intermediate connection structure (such as the fuse 40 ) can be used to connect to the copper busbar positive electrode 21 .

[0060] As some exemplary embodiments, the first surface 11 and the second surface 12 of the bracket 10 may be the front side and the back side of the bracket 10 respectively.

[0061] See also Figure 1 , Figure 2 In one embodiment of the utility model, the bracket 10 is provided with a first surface 11 and a second surface 12, the busbar copper bar 20 is partially embedded in the bracket 10 and partially extends to the first surface 11, the distribution cable 30 is provided on the first surface 11, and the fuse 40 is provided on the second surface 12.

[0062] Such an arrangement can make the busbar copper bar 20 reasonably utilize the internal space of the bracket 10 and the space on the first side 11, and the distribution cable 30 reasonably utilize the space on the first side 11 of the bracket 10, while the fuse 40 reasonably utilizes the space on the second side 12 of the bracket 10, and can avoid mutual interference between the distribution cable 30 and the fuse 40, solve the problem of mutual occupation of space, and make the occupied space of the fuse assembly 100 smaller, which is beneficial to the arrangement of the fuse assembly 100 in the motor controller and can also meet the requirements of high vibration levels.

[0063] See also Figure 1 In one embodiment of the utility model, the first surface 11 is provided with a first limiting groove 111 and a second limiting groove 112 , the positive electrode 31 of the cable is clamped in the first limiting groove 111 , and the negative electrode 32 of the cable is clamped in the second limiting groove 112 .

[0064] In this way, by clamping the cable positive electrode 31 at the first limiting groove 111 and clamping the cable negative electrode 32 at the second limiting groove 112, the cable positive electrode 31 and the cable negative electrode 32 can be limited to prevent the cable positive electrode 31 and the cable negative electrode 32 from rotating during assembly, thereby affecting the reliability of installation.

[0065] It should be noted that the positions of the first limiting groove 111 and the second limiting groove 112 are not specifically limited. Optionally, in order to reasonably utilize the space of the bracket 10, the first limiting groove 111 can be set corresponding to the copper busbar positive electrode 21 so that the cable positive electrode 31 is closer to the copper busbar positive electrode 21, and the second limiting groove 112 can be set corresponding to the copper busbar negative electrode 22 so that the cable negative electrode 31 is closer to the copper busbar negative electrode 22.

[0067] See also Figure 1 In one embodiment of the utility model, the first surface 11 is provided with two second limiting ribs 114 arranged opposite to each other, and a second limiting groove 112 is formed between the two second limiting ribs 114; in this way, the design of the second limiting rib 114 can not only limit the negative electrode 32 of the cable, but also strengthen the bracket 10, which can improve the plastic flow during the injection molding of the bracket 10 to avoid injection molding defects.

[0068] See also Figure 2 In one embodiment of the present invention, the second surface 12 is provided with a mounting groove 121 , and the fuse 40 is disposed in the mounting groove 121 .

[0069] In this way, by installing the fuse 40 in the installation groove 121 of the second surface 12 of the bracket 10, the installation reliability of the fuse 40 can be improved.

[0070] It should be noted that the position of the installation slot 121 is not specifically limited. Optionally, in order to reasonably utilize the space of the bracket 10 , the installation slot 121 can be arranged corresponding to the copper busbar positive electrode 21 so that the fuse 40 is closer to the copper busbar positive electrode 21 .

[0071] See also Figures 3 to 6In one embodiment of the utility model, the copper busbar positive electrode 21 includes a positive input terminal 211, a first connecting section 212 and a positive output terminal 213; the positive input terminal 211 is arranged close to the second surface 12; the side of one end of the first connecting section 212 is close to the second surface 12 and connected to the positive input terminal 211, and the side of the other end is close to the first surface 11; one end of the positive output terminal 213 forms a positive bending portion 2131 and is connected to the side of the first connecting section 212 close to the first surface 11, and the other end extends to the first surface 11.

[0072] Such an arrangement can make the arrangement of the positive electrode input terminal 211, the first connecting section 212 and the positive electrode output terminal 213 of the copper busbar positive electrode 21 more reasonable, so as to fully utilize the space of the bracket 10 and facilitate subsequent connection.

[0073] As some examples, the positive electrode input terminal 211, the first connection section 212 and the positive electrode output terminal 213 may be an integrally formed structure, which can not only ensure connection reliability but also simplify the preparation process.

[0074] See also Figures 3 to 6 In one embodiment of the utility model, the negative electrode 22 of the copper busbar includes a negative electrode input terminal 221, a second connecting section 222, a third connecting section 223 and a negative electrode output terminal 224; the negative electrode input terminal 221 is arranged close to the second surface 12; one end of the second connecting section 222 is connected to the negative electrode input terminal 221, and the other end is inclined toward the first surface 11; one end of the third connecting section 223 is connected to an end of the second connecting section 222 away from the negative electrode input terminal 221; one end of the negative electrode output terminal 224 forms a negative electrode bending portion 2241 and is connected to an end of the third connecting section 223 away from the second connecting section 222, and the other end extends to the first surface 11.

[0075] Such an arrangement can make the arrangement of the negative electrode input terminal 221, the second connecting section 222, the third connecting section 223 and the negative electrode output terminal 224 of the copper bar negative electrode 22 more reasonable, so as to fully utilize the space of the bracket 10 and facilitate subsequent connection.

[0076] As some examples, the negative electrode input terminal 221, the second connection segment 222, the third connection segment 223 and the negative electrode output terminal 224 may be an integrally formed structure, which can not only ensure connection reliability but also simplify the preparation process.

[0077] See also Figure 5 , Figure 6 In one embodiment of the present invention, the positive electrode 31 of the cable is connected to the positive electrode 21 of the copper busbar through a fuse 40 .

[0078] Such an arrangement allows the fuse 40 to act as a bridge, so that the cable positive electrode 31 is arranged on the side of the fuse 40 away from the copper bus positive electrode 21, which can avoid mutual interference between the cable positive electrode 31 and the cable negative electrode 32, making the overall layout of the fuse assembly 100 more reasonable and occupying less space.

[0079] In actual application, the cable positive electrode 31 may be directly connected to the fuse 40 , or may be indirectly connected to the fuse 40 through a connection structure.

[0080] See also Figure 5 , Figure 6 In one embodiment of the present invention, the power distribution cable 30 further includes a connector 33 , and the positive electrode 31 of the cable is connected to the fuse 40 via the connector 33 .

[0081] In this configuration, since the cable positive electrode 31 is disposed on the first surface 11 of the bracket 10 and the fuse 40 is disposed on the second surface 12 of the bracket 10 , the configuration of the connector 33 can make the cable positive electrode 31 more smoothly connected to the fuse 40 .

[0082] In actual application, the shape of the connecting member 33 includes but is not limited to a sheet-shaped, linear, block-shaped or other structural member.

[0083] Furthermore, the connector 33 may be embedded in the bracket 10 or installed on the outside of the bracket 10 , as long as the connection between the positive electrode 31 of the cable and the fuse 40 can be achieved.

[0084] See also Figure 5 , Figure 6 In one embodiment of the present invention, the connecting member 33 is embedded in the bracket 10 .

[0085] In this way, by embedding the connector 33 inside the bracket 10 , the installation reliability of the connector 33 can be improved, so as to improve the connection reliability between the connector 33 and the positive electrode 31 of the cable and the fuse 40 .

[0086] See also Figure 5 , Figure 6 In one embodiment of the present invention, the first end 41 of the fuse 40 is connected to the positive electrode 21 of the copper busbar, and the second end 42 of the fuse 40 is connected to the connecting piece 33 .

[0087] In this configuration, by connecting the copper busbar positive electrode 21 to the first end 41 of the fuse 40, and connecting the cable positive electrode 31 to the second end 42 of the fuse 40 through the connector 33, mutual interference between the cable positive electrode 31 and the cable negative electrode 32 can be better avoided, so that the overall layout of the fuse assembly 100 is more reasonable and less space is occupied.

[0088] See also Figure 5 , Figure 6 In one embodiment of the present invention, the first end 41 is connected to the copper busbar positive electrode 21 through a first bending piece 411 , and the second end 42 is connected to the connecting member 33 through a second bending piece 421 .

[0089] With such arrangement, during the assembly process, a first bending piece 411 can be connected to the first end 41 of the fuse 40, and then the copper busbar positive electrode 21 can be connected to the first bending piece 411, which makes it easier to achieve the connection between the fuse 40 and the copper busbar positive electrode 21; similarly, a second bending piece 421 can be connected to the second end 42 of the fuse 40, and then the connector 33 can be connected to the second bending piece 421, which makes it easier to achieve the connection between the fuse 40 and the connector 33.

[0092] See also Figure 6 In one embodiment of the utility model, the connecting member 33 includes a first connecting piece 331, a second connecting piece 332 and a third connecting piece 333; the first connecting piece 331 is connected to the positive electrode 31 of the cable; one end of the second connecting piece 332 is connected to the first connecting piece 331 and is set at an angle to the first connecting piece 331; the third connecting piece 333 is connected to one end of the second connecting piece 332 away from the first connecting piece 331 and is set at an angle to the second connecting piece 332, and the third connecting piece 333 is connected to the second bending piece 421.

[0093] Such a configuration can make the arrangement of the first connecting piece 331, the second connecting piece 332 and the third connecting piece 333 of the connecting member 33 more reasonable, so as to make full use of the space of the bracket 10, and at the same time facilitate the connection between the connecting member 33 and the positive electrode 31 of the cable through the first connecting member 33, and facilitate the connection between the connecting member 33 and the second bending piece 421 through the third connecting piece 333.

[0094] As some exemplary examples, the first connecting piece 331 , the second connecting piece 332 and the third connecting piece 333 may be an integrally formed structure, which can not only ensure connection reliability but also simplify the preparation process.

[0098] With such arrangement, during the assembly process, the cable can be clamped on the harness claw 122 so as to limit the cable by the harness claw 122 , thereby preventing the cable from shaking in the whole machine.
