[0002] The Hall sensor is a magnetic field sensor made based on the Hall effect, usually used to detect the current. The Hall sensor is widely used in industrial automation technology, detection technology, information processing technology and other fields.

[0003] High-voltage control boxes are commonly used devices in power transmission lines. High-voltage control boxes are generally equipped with specially designed brackets for fixing Hall sensors. When current detection is required, the Hall sensor is fixed in the high-voltage control box through the bracket to achieve current detection by the Hall sensor. The bracket in the high-voltage control box requires a fixed support surface and layout space during installation, which not only makes it difficult to arrange components inside the high-voltage control box, but also causes the high-voltage control box to have larger dimensions, increased weight and cost after the arrangement is completed. At the same time, when the Hall sensor is fixed on the bracket, it is necessary to use screws, cable ties and other parts to assist in installation, which is not only inconvenient to operate, but also increases the assembly process.

[0027] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0028] The terms "first", "second", "third", "fourth" and the like (if any) in the description and claims of the present application are used to distinguish similar objects and not necessarily to describe a particular sequence or order.

[0029] The directional words such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the specification and claims of this application are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional words should not limit the scope of protection requested by this application.

[0030] like Figure 1 and Figure 2 As shown, the Hall sensor fixing member 1 provided in the first embodiment of the present application is used to fix the Hall sensor 2 on the metal member 3, and the Hall sensor 2 is provided with a mounting hole 21 for inserting the Hall sensor fixing member 1. The Hall sensor fixing member 1 is made of elastic material, and the interior of the Hall sensor fixing member 1 is provided with a through groove 11 for inserting the metal member 3 along the axial direction, and the size of the through groove 11 is smaller than the size of the metal member 3. When the metal member 3 is inserted into the through groove 11 by extrusion, the Hall sensor fixing member 1 is elastically deformed and expands outward under the extrusion of the metal member 3, and at the same time, the Hall sensor fixing member 1 forms an extrusion effect on the inner wall of the mounting hole 21 of the Hall sensor 2, so that the outer wall of the Hall sensor fixing member 1 is abutted against the inner wall of the mounting hole 21 of the Hall sensor 2 and fixed.

[0031] Specifically, the metal part 3 can be an electrical connector such as a copper bar or an aluminum bar. The Hall sensor fixing part 1 is an elastic part. When the metal part 3 is inserted into the through groove 11 by extrusion, the Hall sensor fixing part 1 can be elastically deformed and generate an extrusion force and a restoring force. The extrusion force and the restoring force act on the Hall sensor 2 and the metal part 3 respectively, so that the fixation between the metal part 3 and the Hall sensor 2 is more stable. During assembly, the metal part 3 to be detected is inserted into the through groove 11. The metal part 3 can form an extrusion effect on the Hall sensor fixing part 1. At the same time, the Hall sensor fixing part 1 also produces an extrusion effect on the inner wall of the Hall sensor 2, so that the Hall sensor 2, the Hall sensor fixing part 1 and the metal part 3 are fixed to each other, thereby fixing the Hall sensor 2 on the metal part 3; when the Hall sensor 2 needs to be removed from the metal part 3, it is only necessary to pull the metal part 3 out of the through groove 11.

[0032] like Figure 2 As shown, as an embodiment, the Hall sensor fixing member 1 is in a columnar structure to match the shape of the mounting hole 21 of the Hall sensor 2. Specifically, in this embodiment, the Hall sensor fixing member 1 is in a cylindrical structure. Of course, in other embodiments, when the mounting hole 21 of the Hall sensor 2 is in other shapes, the Hall sensor fixing member 1 can also be in other corresponding shapes.

[0033] like Figures 1 to 4 As shown, as an embodiment, a limiting portion 12 is radially protruded on the outer wall of the Hall sensor fixing member 1, and the limiting portion 12 is used to abut against the end of the Hall sensor 2. The limiting portion 12 is used to prevent the Hall sensor fixing member 1 from sliding in the mounting hole 21, and at the same time makes the fixation between the Hall sensor fixing member 1 and the Hall sensor 2 more stable, preventing the Hall sensor fixing member 1 from sliding in the mounting hole 21 during use.

[0034] like Figures 1 to 4 As shown, as an embodiment, the limiting portion 12 includes a first limiting portion 121 and a second limiting portion 122 which are spaced apart from each other, and the first limiting portion 121 and the second limiting portion 122 are respectively arranged corresponding to the two ends of the Hall sensor fixing member 1, and the first limiting portion 121 and the second limiting portion 122 are respectively abutted against the two ends of the Hall sensor 2. Of course, in other embodiments, the limiting portion 12 may be arranged only at one end of the Hall sensor fixing member 1, and the limiting portion 12 may be arranged close to the insertion end of the metal member 3, so as to prevent the Hall sensor fixing member 1 from sliding in the mounting hole 21 when the metal member 3 is inserted into the through slot 11.

[0035] like Figures 2 to 4As shown, as an embodiment, a groove 13 is provided on the outer wall of the Hall sensor fixing member 1, and the groove 13 is located between the first limiting portion 121 and the second limiting portion 122. The Hall sensor 2 is inserted into the groove 13, and the outer wall of the Hall sensor fixing member 1 at the position of the groove 13 abuts against the inner wall of the Hall sensor 2.

[0036] like Figures 1 to 4 As shown, as an embodiment, the first limiting portion 121 and the second limiting portion 122 are two steps, both of which are formed on the outer wall of the Hall sensor fixing member 1, and the two steps are respectively arranged on both sides of the groove 13. The outer diameter size of the Hall sensor fixing member 1 at the position of the groove 13 is not unique, and the outer diameter size can be determined according to the inner diameter size of the mounting hole 21 of the Hall sensor 2. After the metal member 3 is inserted into the through groove 11, the inner wall of the mounting hole 21 of the Hall sensor 2 can be against the bottom wall of the groove 13, and the two steps can clamp the two ends of the Hall sensor 2. Of course, in other embodiments, the limiting portion 12 can also be a protruding structure, a clamp, etc.

[0037] As an implementation manner, the Hall sensor fixing member 1 is made of an insulating and flame-retardant elastic material.

[0038] Specifically, the Hall sensor fixture 1 can be made of insulating and flame-retardant elastic materials such as flame-retardant silicone and flame-retardant rubber. Since it has good insulation performance, when the Hall sensor fixture 1 is installed in the high-voltage control box, there is no need to consider the insulation and electrical clearance issues, and no safety risks will be generated. At the same time, the Hall sensor fixture 1 can meet the flame retardant performance requirements: such as horizontal HB level and vertical V-0 level safety performance requirements.

[0039] like Figure 2 and Figure 4 As shown, as an implementation mode, an uneven structure is provided on the inner wall of the through groove 11 to facilitate the insertion and removal of the metal member 3.

[0040] like Figure 4 As shown, as an embodiment, the uneven structure includes a plurality of spaced protrusions 15, the protrusions 15 are long strip structures extending along the axial direction of the Hall sensor fixing member 1, and a recessed portion 16 is formed between two adjacent protrusions 15. Of course, in other embodiments, the uneven structure may also be other uneven structures, so that the inner wall of the Hall sensor fixing member 1 forms an uneven surface, and the uneven structure may also be a structure such as a convex point or a groove.

[0041] Specifically, since the metal member 3 is generally a long strip structure, and its surface is a planar structure, and since the Hall sensor fixing member 1 is an elastic structure, if the inner wall of the Hall sensor fixing member 1 adopts a planar structure, the metal member 3 will be adsorbed on the inner wall of the Hall sensor fixing member 1, making it difficult for the metal member 3 to be inserted into the through groove 11. By providing a plurality of protrusions 15 on the inner wall of the Hall sensor fixing member 1, the contact area between the metal member 3 and the inner wall of the Hall sensor fixing member 1 is reduced, and the protrusions 15 can play a guiding role when the metal member 3 is inserted, thereby facilitating the insertion of the metal member 3 into the through groove 11.

[0042] like Figure 1 and Figure 2 As shown, as an embodiment, the Hall sensor fixing member 1 includes at least two clamping blocks 14 that are separated from each other. When the at least two clamping blocks 14 are inserted into the mounting hole 21, a gap is formed between the at least two clamping blocks 14, and the through groove 11 is formed by the gap.

[0043] like Figure 1 and Figure 2 As shown, as an embodiment, there are two clamping blocks 14, the two clamping blocks 14 are arranged opposite to each other, the through slot 11 is formed by the gap between the two clamping blocks 14, and the metal member 3 is clamped between the two clamping blocks 14. Of course, in other embodiments, the number of clamping blocks 14 can also be more, such as three, four or more, and the number of clamping blocks 14 can be determined according to actual needs.

[0044] In other embodiments, the Hall sensor fixing member 1 may also include at least two clamping blocks 14 connected to each other, and the clamping blocks 14 are connected through a connecting portion on at least one side of the through slot 11. For example, there are two clamping blocks 14, the two clamping blocks 14 are arranged opposite to each other, and a connecting portion is arranged between the two clamping blocks 14 on one side of the through slot 11 to connect the two clamping blocks 14; or connecting portions are arranged between the two clamping blocks 14 on both sides of the through slot 11 to connect the two clamping blocks 14 (such as Figure 5 As shown). The connecting portion may be made of elastic material, so it does not affect the fixation of the Hall sensor fixing member 1.

[0045] like Figures 2 to 4 As shown in the figure, as an embodiment, the inner wall of each clamping block 14 is provided with a plurality of protrusions 15, and the outer wall of each clamping block 14 is provided with a limit portion 12 and a groove 13. Each clamping block 14 has two sides along a certain radial direction (from Figure 2 From a middle perspective, that is, the top and bottom of the clamping block 14 can be a planar structure or an arc-shaped structure.

[0046] Specifically, since the outer diameter of the Hall sensor fixing member 1 is generally close to the inner diameter of the mounting hole 21 of the Hall sensor 2, and the outer wall of the Hall sensor fixing member 1 is provided with a limiting portion 12, the Hall sensor fixing member 1 can be conveniently installed in the mounting hole 21 of the Hall sensor 2 by separating the Hall sensor fixing member 1 into two clamping blocks 14. Specifically, during installation, the two clamping blocks 14 are first installed in the mounting hole 21 respectively, so that the Hall sensor 2 is stuck in the groove 13 on the clamping blocks 14, and then the metal member 3 to be detected is inserted into the gap between the two clamping blocks 14. When the metal member 3 is inserted into the gap between the two clamping blocks 14, the metal member 3 can squeeze the two clamping blocks 14 at the same time, so that the Hall sensor 2 is fixed on the metal member 3; when the Hall sensor 2 needs to be removed from the metal member 3, it is only necessary to pull the metal member 3 out of the gap between the two clamping blocks 14, and at this time, the two clamping blocks 14 can also be conveniently taken out from the mounting hole 21.

[0047] like Figure 5 As shown, as another embodiment, the Hall sensor fixing member 1 is an integrated structure, and the Hall sensor fixing member 1 is a cylindrical structure. A through groove 11 is provided in the Hall sensor fixing member 1, and the inner walls on opposite sides of the through groove 11 are provided with protrusions 15, and the outer wall of the Hall sensor fixing member 1 is provided with a groove 13 and a limit portion 12. The Hall sensor fixing member 1 of the integrated structure can also achieve the above functions, but it is necessary to pay attention to controlling the size of the limit portion 12 to prevent the Hall sensor fixing member 1 from being difficult to insert into the mounting hole 21 of the Hall sensor 2.

[0048] like Figure 1 and Figure 2 As shown, the first embodiment of the present application also provides a Hall sensor assembly, including a Hall sensor 2 and a metal part 3. The Hall sensor 2 is provided with a mounting hole 21, and the Hall sensor assembly also includes the Hall sensor fixing part 1 mentioned above, the Hall sensor fixing part 1 is inserted into the mounting hole 21, and the metal part 3 is inserted into the through groove 11. The Hall sensor assembly can be used in the field of automotive industry technology, specifically in the power system, body control system, traction control system and anti-lock braking system of the automobile.

[0049] The advantages of the Hall sensor fixing member 1 and the Hall sensor assembly provided by the embodiment of the present application are:

[0050] 1. Good safety performance: The Hall sensor fixture 1 is made of flame-retardant insulating elastic material (such as flame-retardant silicone, flame-retardant rubber, etc.). Since it has good insulation performance, when the Hall sensor fixture 1 is installed in the high-voltage control box, there is no need to consider insulation and electrical clearance issues, and there will be no safety risks. At the same time, the Hall sensor fixture 1 can meet the flame retardant performance requirements: horizontal HB level and vertical V-0 level national standard safety performance requirements.

[0051] 2. Easy installation and disassembly, good parts versatility: The Hall sensor 2 is fixed on the metal part 3 using the Hall sensor fixing part 1, and there is no need to use screws, cable ties and other parts to assist in the installation. It is only necessary to first install the two clamping blocks 14 in the mounting holes 21, and then insert the metal part 3 to be detected into the gap between the two clamping blocks 14 to complete the installation; when the Hall sensor 2 needs to be removed from the metal part 3, it is only necessary to pull the metal part 3 out of the gap between the two clamping blocks 14, so the Hall sensor assembly has the advantages of easy operation and simple installation. At the same time, since the Hall sensor fixing part 1 adopts a standardized design and is molded, the parts have good consistency and stable size. It only needs to specify the thickness of the metal part 3 to be used in all high-voltage control boxes (not shown), and has good universal performance.

[0052] 3. Good fastening performance and high reliability: Since the Hall sensor fixing part 1 is an elastic structure, when the metal part 3 is inserted into the through groove 11, the Hall sensor fixing part 1 can undergo elastic deformation and generate extrusion force and restoring force, which act on the Hall sensor 2 and the metal part 3 respectively, making the fixation between the metal part 3 and the Hall sensor 2 more stable. At the same time, by setting a limiter 12 on the Hall sensor fixing part 1, the limiter 12 can prevent the Hall sensor 2 from sliding on the Hall sensor fixing part 1, making the fixation between the Hall sensor 2 and the Hall sensor fixing part 1 more stable. After experimental testing and actual use verification, the Hall sensor fixing part 1 can ensure the fastening and reliability of the Hall sensor 2, and meet the installation and use requirements of the Hall sensor 2.

[0053] 4. Small size, reduced occupied space: The Hall sensor fixing part 1 has a compact structure and small size, eliminating the bracket for fixing the Hall sensor 2, reducing the internal occupied space of the high-voltage control box, solving the problem of difficult arrangement of components inside the high-voltage control box, and reducing the external dimensions of the high-voltage control box, and can improve the adaptability of the high-voltage control box in the installation and arrangement of the vehicle.

[0054] 5. Simple structure and low cost: The traditional bracket for fixing the Hall sensor 2 needs to be designed and designed according to the specific usage. This process takes a lot of time. At the same time, the bracket needs to go through multiple processes such as sheet metal cutting, bending, welding, and spraying during production, which not only takes a long time, but also has high parts manufacturing costs. The Hall sensor fixing part 1 of this embodiment has a simple structure and adopts a standardized design. It only needs to be designed and molded once, and can be formed once, and can be mass-produced, which greatly reduces the production and manufacturing costs, avoids repeated design, and saves labor costs.

[0055] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
