[0019] The embodiments of the present application will be described in detail below with reference to the drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the scope of protection of the present application.

[0020] Combined with Figure 1 and Figure 2 As shown, the power distribution unit according to a specific embodiment of the present application includes a support frame 1 and a current sensor 2. The current sensor 2 is fixed to the support frame 1 through two connection points 3, and the two connection points 3 are a left connection point and a right connection point respectively. At least two protrusions 4 are provided at the support frame 1. The protrusions 4 are used to abut against the current sensor 2. Specifically, the protrusions 4 abut against the housing of the current sensor 2 and provide support. The protrusions 4 are arranged on both sides with respect to the connection line of the connection points 3, that is, two protrusions 4 are respectively provided on both sides with respect to the connection line of the connection points 3. Of course, the number of protrusions can also be other numbers, for example, one protrusion is respectively provided on both sides with respect to the connection line of the connection points 3.

[0021] In this technical solution according to the present application, protrusions 4 are respectively provided on both sides of the wire connecting the connection points 3 for fixing the current sensor 2 to abut against the current sensor 2, thereby reducing the vibration of the current sensor 2 about the wire of the connection points 3, and thus avoiding damage to the electronic components in the current sensor 2. The electronic components in the current sensor 2 include, for example, coils, circuit boards, and chip capacitors.

[0022] In the embodiment shown in the figure, the current sensor 2 is fixed to the support frame 1 through two threaded connection points 3. The extending direction of the threaded connection member is as shown by the dashed line in Figure 1 . Of course, the current sensor can also be fixed to the support frame 1 by other connection methods. The wire connecting the two threaded connection points 3 is in a horizontal plane, that is, substantially flush with the horizontal line. The protrusions 4 are respectively arranged above and below the wire connecting the two threaded connection points 3.

[0023] In an embodiment not shown, the current sensor is fixed to the support frame through a plurality of connection points. The plurality of connection points may be arranged along the same straight line or the wires between the plurality of connection points form a plurality of straight lines. In the case where the wires between the plurality of connection points form a plurality of straight lines, the protrusions are arranged on both sides of one or more of the wires connecting the connection points to reduce the vibration of the current sensor.

[0024] The support frame 1 includes reinforcing ribs 11, and the reinforcing ribs 11 are used to increase the strength and stiffness of the support frame 1. The protrusions 4 are provided on the reinforcing ribs 11. Thus, the required length of the protrusions can be shortened, and the strength of the protrusions provided on the reinforcing ribs can be ensured compared to separately provided protrusions.

[0025] Exemplarily, the support frame 1 is used to carry the input unit of the power distribution unit, and the input unit includes a copper busbar 5, and the copper busbar 5 serves as a carrier for input current. The current sensor 2 at least partially surrounds the copper busbar 5 to measure the magnitude of the input current.

[0026] Of course, the support frame 1 can also be used to carry other functional modules of the power distribution unit, such as an output unit. Correspondingly, the current sensor 2 can also be used to measure other parameters, such as the magnitude of the output current.

[0027] The protrusion 4 can be made of one or more of metal, rubber, and plastic. The protrusion 4 can be integrally molded with the support frame 1 from the same material, such as plastic, by one injection molding. The protrusion 4 is, for example, in interference fit with the housing of the current sensor 2 with an interference amount of 0.5 mm - 1 mm, so that the protrusion 4 can reliably abut against the current sensor 2 without damaging the current sensor 2. The protrusion 4 made of other materials, for example, can also be integrally molded with the support frame 1. If the protrusion 4 is made of metal or rubber, the high-frequency vibration of the current sensor 2 can be effectively suppressed. Exemplarily, the protrusion 4 is configured to be generally semi-circular, with a height of 1 mm, a radius of 1 mm, and a fillet of 0.5 mm.

[0028] Combined Figure 2 As shown, the support frame 1 according to a specific embodiment of the present application includes at least two connection points 3 for fixing a current sensor. At least two protrusions 4 are provided at the support frame 1, and the protrusions 4 are used to abut against the current sensor. The protrusions 4 are arranged on both sides with respect to the connection line of the connection points 3.

[0029] In this technical solution, the protrusions 4 are respectively provided on both sides of the connection line of the connection points 3 for fixing the current sensor to abut against the current sensor, thereby reducing the vibration of the current sensor with respect to the connection line of the connection points 3, and thus avoiding damage to the electronic components in the current sensor.

[0030] The present application further includes a vehicle equipped with the power distribution unit according to any one or more of the foregoing embodiments. Therefore, the technical features and the technical effects thereof are corresponding to the foregoing description, and thus will not be elaborated herein.
