[0028] According to a first aspect of this utility model, a three-phase wire fixing bracket is provided, such as... Figures 1 to 4 As shown, the three-phase wire fixing bracket is used for fixing and auxiliary connection of the three-phase wire body 204. The three-phase wire fixing bracket includes a bracket body 101. In the following description, reference will be made to... Figures 1 to 4 This section describes the detailed structure of the support body 101 of the three-phase line fixing bracket.

[0029] like Figure 1 As shown, in the embodiment, the three-phase wire body 204 can be, for example, a component commonly used in vehicles in the prior art. For ease of description, the three-phase wire body 204 in the embodiment may include a mounting part 205 that is mounted on the bracket body 101. The mounting part 205 is disposed on the wire of the three-phase wire body 204, and the way it is disposed may be, for example, by connecting through an adapter frame.

[0030] Specifically, the support body 101 can be formed into an approximately rectangular plate structure. Guide grooves 102 are provided at both ends of the rectangular plate structure. The guide grooves 102 are used to fix the three-phase wire body 204. The three-phase wire body 204 itself is provided with welding bolts 206 for connection. By inserting the welding bolts 206 into the guide grooves 102 and cooperating with nuts, the three-phase wire body 204 is fixed to the support body 101. To ensure a stable connection, a guide groove 102 is provided at each end of the support body 101. The two guide grooves 102, in conjunction with the two welding bolts 206 of the three-phase wire body 204, ensure a stable connection between the support body 101 and the three-phase wire body 204.

[0031] Furthermore, the bracket body 101 has a fixed end 103 that mates with the vehicle body mounting bracket beam and an mounting end 104 with an opening of a guide groove 102, the mounting end 104 facing away from the fixed end 103. The mounting end 104 and the fixed end 103 can be understood as the two ends of the bracket body 101 in the width direction, which is an approximately cuboid plate structure. The bracket body 101 is fixedly mounted to the vehicle body mounting bracket beam via the fixed end 103, and the guide groove 102 of the bracket body 101 is opened at the mounting end 104. When the three-phase wire body 204 is connected to the bracket body 101, the mounting part 205 of the three-phase wire body 204 is moved from the mounting end 104 toward the fixed end 103 and engaged in the guide groove 102 to achieve installation and fixation.

[0032] The three-phase wire fixing bracket, through the cooperation of the bracket body 101 and the guide grooves 102 at both ends of the bracket body 101, allows the three-phase wire body 204 to be installed and fixed to the bracket body 101. Simultaneously, the two guide grooves 102 at both ends of the bracket body 101, in conjunction with the two welding bolts 206 of the three-phase wire body 204, ensure a stable connection between the bracket body 101 and the three-phase wire body 204. This three-phase wire fixing bracket has a simple overall structure and occupies a small area. Since the guide grooves 102 are located at the ends of the mounting bracket beam facing away from the vehicle body, the three-phase wire body 204 can be directly connected to the bracket body 101 through a snap-fit ​​method. The entire assembly process is simple and convenient, requires no pre-reserved installation space, and can adapt to hybrid vehicle layouts.

[0033] Preferably, such as Figures 1 to 4 As shown, in this embodiment, the opening of the guide groove 102 is formed in a trumpet shape, and the size of the trumpet-shaped opening gradually decreases along the direction in which the opening of the guide groove 102 extends toward the bottom of the guide groove 102. To further facilitate the docking of the three-phase wire body 204 with the bracket body 101, the opening of the guide groove 102 is formed in a trumpet shape. The larger opening size helps the operator to dock the welding bolts 206 of the three-phase wire body 204 with the guide groove 102 of the bracket body 101.

[0034] Preferably, such as Figures 1 to 4 As shown, in this embodiment, the vehicle body mounting bracket beam includes intersecting crossbeams 201 and longitudinal beams 202. The area enclosed by the intersection of the crossbeams 201 and longitudinal beams 202 forms a three-phase wire through-hole 203. The mounting portion 205 of the three-phase wire body 204 is fixedly mounted to the bracket body 101, and the three-phase wire body 204 passes through the three-phase wire through-hole 203. To facilitate the passage of the three-phase wire body 204 through the three-phase wire through-hole 203, the bracket body 101 needs to be positioned close to the three-phase wire through-hole 203. In this embodiment, the bracket body 101 is positioned on the longitudinal beam 202 and close to the crossbeam 201.

[0035] Preferably, in the embodiment, the fixed end 103 of the support body 101 is welded to the longitudinal beam 202. In order to ensure that the thin support body 101 can be stably connected to the longitudinal beam 202, welding is used to achieve a fixed connection.

[0036] Preferably, such as Figures 1 to 4 As shown in the embodiment, in order to enable the support body 101 to be welded to the longitudinal beam 202, welding holes 106 are also provided on the support body 101.

[0037] Preferably, such as Figures 1 to 4 As shown, in this embodiment, a clearance portion 105 is provided at one end of the support body 101 near the crossbeam 201. The clearance portion 105 avoids the end of the crossbeam 201. To avoid interference and facilitate welding of the support body 101, the clearance portion 105 is provided at the end of the support body 101 near the crossbeam 201. The clearance portion 105 is recessed from the end face of the support body 101 toward the direction in which the support body 101 has a guide groove 102. That is, the clearance portion 105 forms a notch on the support body 101, and this notch can be used to avoid the crossbeam 201.

[0038] Preferably, such as Figures 1 to 4 As shown, in this embodiment, if the clearance portion 105 is not considered, the support body 101 can be formed as a symmetrical structure, that is, the two guide grooves 102 provided at both ends of the support body 101 are symmetrically arranged along the centerline of the support body 101. The two symmetrically arranged guide grooves 102 facilitate the connection of the two welding bolts 206 of the three-phase line body 204.

[0039] Preferably, such as Figures 1 to 4 As shown, in this embodiment, to further facilitate the docking of the three-phase line body 204 and the bracket body 101, the length of the bracket body 101 in a first direction corresponds to the length of the mounting portion 205 of the three-phase line body 204. The first direction can be understood as the length direction of the bracket body 101 or the length direction of the crossbeam 201. Furthermore, to ensure that the welding bolt 206 corresponds to the guide groove 102, the welding bolt 206 is positioned on the end face of the mounting portion 205 facing the bracket body 101.

[0040] The assembly process of the three-phase wire fixing bracket is as follows: First, the bracket body 101 is welded to the vehicle mounting bracket beam through the fixing end 103; Second, the setting direction of the welding bolts 206 of the three-phase wire body 204 is checked to ensure that the setting direction of the welding bolts 206 of the three-phase wire body 204 corresponds to the installation direction; Third, the operator pulls the three-phase wire body 204 with one hand to make the welding bolts 206 pass through the guide groove 102 and connect them in place. Then, the nut is used to fix the three-phase wire body 204 to the bracket body 101 in conjunction with the welding bolts 206.

[0041] This three-phase wire fixing bracket, through the cooperation of the bracket body and guide grooves at both ends of the bracket body, allows the three-phase wire body to be installed and fixed to the bracket body. Simultaneously, the two guide grooves at each end of the bracket body, in conjunction with two welding bolts on the three-phase wire body, ensure a stable connection between the bracket body and the three-phase wire body. The overall structure of this three-phase wire fixing bracket is simple and occupies a small area. Because the guide grooves are located at the ends of the mounting bracket beam facing away from the vehicle body, the three-phase wire body can be directly connected to the bracket body through a snap-fit ​​method. The entire assembly process is simple and convenient, requires no pre-reserved installation space, and can adapt to hybrid vehicle layouts.

[0042] In addition, such as Figures 1 to 4 As shown, according to a second aspect of this utility model, a three-phase wire fixing structure is provided, the three-phase wire fixing structure including the three-phase wire fixing bracket as described above. The three-phase wire fixing structure includes a bracket body 101, a three-phase wire body 204, and a vehicle body mounting bracket beam. Through the cooperation of these three components, the three-phase wire body 204 can be stably mounted on the vehicle body mounting bracket beam via the bracket body 101.

[0043] Furthermore, according to a third aspect of the present invention, a vehicle is provided, the vehicle including the three-phase wire fixing structure as described above.

[0044] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them.
