[0038] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, the orientation words such as 'up' and 'down' generally refer to the up and down of the device in the actual use or working state, and the specific is the direction of the drawing in the drawing; and 'inner' and 'outer' are relative to the outline of the device.

[0039] The Hall sensor bracket is a device specially designed to fix the Hall sensor, and its main purpose is to ensure that the Hall sensor can work stably and reliably in a specific application scenario. The Hall sensor is widely used in various electronic devices, such as automotive electronic systems, motor control, etc., to detect changes in the magnetic field or the position movement of objects, etc. In this way, the horizontal direction occupied by the high-voltage distribution box (hereinafter referred to as PDU) installed with the Hall sensor bracket will be larger, and the space in each direction cannot be fully utilized. Among them, PDU (Power Distribution Unit, high-voltage distribution unit) is a key component in the high-voltage system of new energy vehicles, responsible for power distribution and management in the high-voltage system. PDU not only provides functions such as charging and discharging control, high-voltage component power-on control, circuit overload and short circuit protection, high-voltage sampling, low-voltage control for the whole vehicle, but also plays an important role in protecting and monitoring the operation of the high-voltage system.

[0040] To solve the above problems, in a first aspect, the application provides a Hall sensor assembly, such as Figure 1As shown, the Hall sensor assembly can be applied to a high-voltage power distribution box 300 (referred to as PDU) for monitoring the state of each circuit inside the high-voltage power distribution box 300. The Hall sensor assembly can also be applied to a vehicle, which can specifically include an electric vehicle or a hybrid vehicle. For electric vehicles or hybrid vehicles, the Hall sensor assembly can be used to monitor the current between the battery and the motor.

[0041] Please refer to Figure 2 The Hall sensor assembly includes a Hall sensor 100 and a bracket body 20. The Hall sensor 100 is multiple, and can be used to detect changes in current or magnetic field. In some examples, please refer to Figure 6 The multiple Hall sensors 100 can include a first Hall sensor 11, a second Hall sensor 12, a third Hall sensor 13, and a fourth Hall sensor 14.

[0042] Please refer to Figure 6 The bracket body 20 is provided with a first mounting portion 21 and a second mounting portion 22. At least one Hall sensor is mounted on the first mounting portion 21, and at least one Hall sensor is mounted on the second mounting portion 22. The first mounting portion 21 and the second mounting portion 22 are arranged along a first direction, and the first direction has an angle with the horizontal direction. Thus, the Hall sensor mounted on the first mounting portion 21 and the Hall sensor mounted on the second mounting portion 22 can be arranged along the first direction. Since the first direction has an angle with the horizontal direction, the arrangement direction of the Hall sensor mounted on the first mounting portion 21 and the Hall sensor mounted on the second mounting portion 22 has an angle with the horizontal direction, thereby reducing the occupation of space in the horizontal direction.

[0043] In some examples, the first Hall sensor 11 can be mounted on the first mounting portion 21, and the second Hall sensor 12 can be mounted on the second mounting portion 22.

[0044] The Hall sensor and the first mounting portion 21 are detachably connected, such as screwing, clamping, etc.

[0045] The Hall sensor and the second mounting portion 22 are detachably connected, such as screwing, clamping, etc.

[0046] Please refer to Figure 6 In some embodiments, the bracket body 20 is further provided with a third mounting portion 23, and at least one Hall sensor is mounted on the third mounting portion 23. The third mounting portion 23 and the second mounting portion 22 are arranged along a second direction, and the second direction has an angle with the first direction. In some examples, the third Hall sensor 13 can be mounted on the third mounting portion 23. Thus, the space in the first direction and the second direction can be fully utilized, and the structure of the Hall sensor assembly is more compact.

[0047] Please combine Figure 6 In some embodiments, the first direction is a vertical direction, and the second direction is a horizontal direction. In this way, the Hall sensors mounted on the first mounting portion 21 and the Hall sensors mounted on the second mounting portion 22 can be arranged along the vertical direction, thereby saving space in the horizontal direction.

[0048] Since there are usually more components arranged in the X direction of the vehicle and the Y direction of the vehicle, it is more crowded, and even the space of the passenger compartment may be occupied. It should be noted that in the field of automotive engineering, the X direction of the vehicle, the Y direction of the vehicle, and the Z direction of the vehicle are the basic components of defining the vehicle coordinate system. The X direction of the vehicle usually refers to the length direction of the vehicle, that is, the front-rear direction of the vehicle. The Y direction of the vehicle represents the width direction of the vehicle, that is, the left-right direction of the vehicle. The Z direction of the vehicle represents the vertical direction, that is, the up-down direction of the vehicle. On an ideal flat ground, the X axis and the Y axis of the vehicle coordinate system are both in the horizontal direction, corresponding to the forward direction and the lateral direction of the vehicle, respectively. In this application, when the Hall sensor assembly is applied to a vehicle, by arranging the first mounting portion 21 and the second mounting portion 22 along the first direction, the first direction is a vertical direction, and the Hall sensors mounted on the first mounting portion 21 and the Hall sensors mounted on the second mounting portion are arranged along the vertical direction, thereby saving space in the horizontal direction, that is, saving space in the X direction of the vehicle and the Y direction of the vehicle, and fully utilizing the space in the Z direction of the vehicle.

[0049] When the Hall sensor assembly is applied to a PDU, the PDU provided with the Hall sensor assembly is also more compact in the horizontal direction, occupies less space in the horizontal direction, and improves the space utilization rate of the PDU. Therefore, when the PDU is installed on a vehicle, it can occupy less space in the X direction of the vehicle and the Y direction of the vehicle.

[0050] Please combine Figure 6 In some embodiments, the bracket body 20 further comprises a fourth mounting portion 24, the fourth mounting portion 24 is arranged along the second direction with the first mounting portion 21, and the fourth mounting portion 24 is arranged along the first direction with the third mounting portion 23. In this way, four mounting portions are provided on one bracket body 20, which are the first mounting portion 21, the second mounting portion 22, the third mounting portion 23, and the fourth mounting portion 24, and one or more Hall sensors are provided on each of the four mounting portions. By setting the positions of the four mounting portions, the Hall sensors mounted on the four mounting portions can be arranged along the first direction and the second direction, fully utilizing the space in each direction, and making the Hall sensor assembly compact.

[0051] Please combine Figure 6In some embodiments, the first mounting portion 21 and the fourth mounting portion 24 are symmetrically distributed on two sides of the bracket body 20; and / or the second mounting portion 22 and the third mounting portion 23 are symmetrically distributed on two sides of the bracket body.

[0052] In some examples, the first mounting portion 21 and the fourth mounting portion 24 are symmetrically distributed on two sides of the bracket body 20. Thus, the Hall sensor mounted on the first mounting portion 21 and the Hall sensor mounted on the fourth mounting portion 24 can be symmetrically distributed on two sides of the bracket body 20.

[0053] In some examples, the second mounting portion 22 and the third mounting portion 23 are symmetrically distributed on two sides of the bracket body. Thus, the Hall sensor mounted on the second mounting portion 22 and the Hall sensor mounted on the third mounting portion 23 can be symmetrically distributed on two sides of the bracket body 20.

[0054] In some examples, the first mounting portion 21 and the fourth mounting portion 24 are symmetrically distributed on two sides of the bracket body 20. The second mounting portion 22 and the third mounting portion 23 are symmetrically distributed on two sides of the bracket body. Thus, the Hall sensor mounted on the first mounting portion 21 and the Hall sensor mounted on the fourth mounting portion 24 can be symmetrically distributed on two sides of the bracket body 20. Meanwhile, the Hall sensor mounted on the second mounting portion 22 and the Hall sensor mounted on the third mounting portion 23 can be symmetrically distributed on two sides of the bracket body 20. In addition, the first mounting portion 21 and the second mounting portion 22 are arranged along the first direction, and the fourth mounting portion 24 and the third mounting portion 23 are arranged along the first direction. That is, the four mounting portions are arranged symmetrically in two layers, and the structure is compact.

[0055] In the related art, most of the Hall sensor brackets of high-voltage distribution boxes (hereinafter referred to as PDUs) are single. When there are multiple Hall sensors, the multiple Hall sensors are arranged in the horizontal direction, which occupies a large space in the horizontal direction. The present application provides a Hall sensor assembly which can install multiple Hall sensors on the bracket body and achieve the effect of multiple-in-one. At the same time, the occupation in the horizontal direction is reduced.

[0056] In a second aspect, the present application also provides a high-voltage distribution box 300 for a vehicle, which comprises a box body 310 and the Hall sensor assembly described above. When the Hall sensor assembly is applied to the high-voltage distribution box 300, the high-voltage distribution box 300 provided with the Hall sensor assembly is also more compact in structure in the horizontal direction, occupies less space in the horizontal direction, and improves the space utilization rate of the high-voltage distribution box 300.
