DETAILED DESCRIPTION
[0046] In order to make the content of the utility model more easily be clearly understood, below according to specific embodiment and combining with the drawings, the utility model is further detailed.
[0047] Example 1:
[0048] Please refer to Figures 1 to 5 As shown in the figure, the embodiment provides a kind of Hall control panel assembly, comprising: control panel 1, with the detachable adapter of control panel 1 Hall bracket 2, and the Hall element 3 suitable for being embedded in Hall bracket 2.
[0049] Hall bracket 2 includes the bracket body 21 formed with the accommodation cavity for embedding Hall element 3, and the assembly 22 for being detachably assembled with control panel 1 on the side end of bracket body 21;Control panel 1 is equipped with the adapter 11 for being assembled with assembly 22.It is said that the relative position of Hall bracket 2 whole and control panel 1 is determined by the cooperation of assembly 22 and adapter 11.Based on this structure, further, the side end of bracket body 21 equipped with assembly 22 is also equipped with the connecting hole 24 suitable for the pin of Hall element 3 embedded in accommodation cavity to pass through;The pin of Hall element 3 is suitable for being connected with control panel 1 by welding.Such, for the sensing portion 32 of Hall element 3, Hall bracket 2 plays the role of supporting and limiting it, as long as the position of Hall bracket 2 relative to control panel 1 is fixed, the sensing portion 32 of Hall element 3 is not possible to produce relative to control panel 1 Inclination.
[0050] On the basis of the above structure, it needs to be explained that in the first alternative embodiment, the assembling part 22 is a pair of positioning columns protruding from the side end of the bracket body 21, and the positioning columns are located on both sides of the connecting hole 24 respectively; and the adapting part 11 is a pair of positioning holes provided on the control panel 1 and adapted to be inserted into the positioning columns one by one. The drawings of the present embodiment are only shown as an example in this way. Of course, in the second alternative embodiment, the assembling part 22 is a pair of positioning holes recessed in the side end of the bracket body 21, and the positioning holes are located on both sides of the connecting hole 24 respectively; and the adapting part 11 is a pair of positioning columns protruding from the control panel 1 and adapted to be inserted into the positioning holes one by one. In addition, in the third alternative embodiment, the assembling part can be provided with both positioning columns and positioning holes, and the corresponding adapting part 11 is also provided with both positioning holes and positioning columns. Based on this, the specific conditions of the assembling part and the adapting part 11 in the present embodiment are not absolutely limited.
[0051] Next, it also needs to be explained that in order to facilitate the Hall element 3 to be loaded into the accommodating cavity in the bracket body 21, the side end of the bracket body 21 away from the connecting hole 24 is also provided with a mounting port 23 adapted for the Hall element 3 to be embedded in the bracket body 21. The specific shape of the mounting port 23 is not absolutely limited in the present embodiment, as long as it can meet the embedding requirement of the Hall element 3. In this regard, in the process of assembling the Hall element 3 and the Hall bracket 2, the lead 31 of the Hall element 3 first enters the mounting port 23, and as the lead 31 gradually penetrates, finally, the lead 31 of the Hall element 3 extends from the connecting hole 24, thereby facilitating the welding of the lead 31 and the control panel 1.
[0052] In summary, for the Hall control panel assembly of the present embodiment, the cooperation between the Hall element 3 and the control panel 1 not only has the welding of the lead 31 and the control panel 1, but also has the restraint of the Hall bracket 2 to the Hall element 3, and the position of the Hall bracket 2 relative to the control panel 1 is positioned through the cooperation of the assembling part and the adapting part 11, so that the Hall element 3 relative to the control panel 1 will not shake, that is, the use state of the Hall element 3 in the overall Hall control panel assembly can be ensured to be stable and reliable.
[0053] Embodiment 2:
[0054] Please refer to Figures 1 to 8 On the basis of the Hall control panel assembly of the present embodiment, the present embodiment provides an electric motor, at least comprising: a stator and a rotor 5 used in cooperation, and the Hall control panel assembly of the present embodiment connected with the coil skeleton 4 of the stator; wherein the control panel 1 of the Hall control panel assembly is fixedly connected with the coil skeleton 4 to make the Hall bracket 2 distributed between the rotor 5 and the coil skeleton 4.
[0055] On the basis of the above structure, it needs to be explained that from the perspective of the application of the motor in the circulating pump, the motor is generally placed along the axial direction of the rotor 5, and the coil skeleton 4 is located below the rotor 5. For the Hall control board assembly, the position of the Hall bracket 2 relative to the rotor 5 is positioned through the assembly part and the matching part 11. Based on this, the Hall bracket 2 is prevented from tilting away from the rotor 5, that is, the Hall bracket 2 is prevented from falling downward. The bracket body 21 of the Hall bracket 2 is carried on the coil skeleton 4, that is, the coil skeleton 4 plays a role of supporting the Hall bracket 2 from below from the perspective of the use of the circulating pump. Thus, the Hall element 3 can be arranged in the receiving cavity of the Hall bracket 2 in a manner parallel to the axial direction of the rotor 5. In this way, the interference of the Hall element 3 with the rotor 5 can be avoided, and the distance between the Hall element 3 and the rotor 5 can be controlled by precisely controlling the assembly position of the Hall bracket 2 and the control board 1. Thus, the strength of the signal sensed by the Hall element 3 can be enhanced, thereby improving the sensitivity of the Hall element 3 and making the operation of the motor more reliable and stable.
[0056] Next, in conjunction with the drawings, an example of a specific optional case is described. The bracket body 21 includes a transverse portion 211 and a longitudinal portion 212 forming a flat T-shaped structure. The connecting hole 24 is provided in the transverse portion 211 of the bracket body 21, and the mounting port 23 is provided in the longitudinal portion 212 of the bracket body 21. The size of the transverse portion 211 toward the side end of the control board 1 is greater than the size of the longitudinal portion 212 toward the transverse portion 211. In this way, the pins (generally including multiple prongs) of the Hall element 3 can be relatively separated to facilitate welding with the control board 1. Moreover, the bracket body 21 in the flat T-shaped structure can reduce its weight, thereby reducing the weight borne by the coil skeleton 4.
[0057] Based on the above, in an optional embodiment, in order to improve the overall firmness of the bracket body 21, the bracket body 21 further includes a pair of inclined support portions 213 provided between the transverse portion 211 and the longitudinal portion 212 and located on both sides of the longitudinal portion 212. In this structure, it needs to be explained that the receiving cavity penetrates through the transverse portion 211, the longitudinal portion 212, and the inclined support portion 213, and the transverse portion 211, the longitudinal portion 212, and the inclined support portion 213 are integrally processed and formed. In this way, during the process of embedding the Hall element 3 into the Hall bracket 2, the lead 31 of the Hall element 3 starts to be relatively separated under the guidance of the inclined support portion 213. Thus, the alignment efficiency of the lead 31 and the corresponding matching point on the control board 1 is improved, and the overall assembly efficiency of the Hall control board assembly is improved.
[0058] In addition, it is also necessary to point out that, in one implementation, for the Hall element 3 embedded in the bracket body 21, in order to facilitate the adjustment of the sensitivity of the Hall element 3 to the rotor 5, the embodiment is designed as follows: a hollow opening 28 suitable for exposing the sensing part 32 of the Hall element 3 is further arranged on one side wall surface of the bracket body 21 along the depth direction of the accommodating cavity and is in communication with the mounting opening 23. Based on this structure, when the control board 1 and the coil skeleton 4 are assembled in place, the hollow opening 28 of the Hall bracket 2 can face the rotor 5 or face away from the rotor 5, and when the hollow opening 28 faces the rotor, the sensing sensitivity of the Hall element 3 is greater than that when it faces away from the rotor 5. Therefore, combined with the different magnetization conditions of the magnetic ring on the different rotors 5, the orientation of the hollow opening 28 of the Hall bracket 2 in the actual use can be adjusted.
[0059] In summary, for the motor of the embodiment, the Hall element 3 can be located between the coil skeleton 4 of the stator and the rotor 5. Because the Hall element 3 is restrained by the Hall bracket 2, the sensing part 32 of the Hall element 3 can sense the rotor 5 in a direction substantially parallel to the axial direction of the rotor 5, thereby preventing the problem of reduced sensing sensitivity caused by the sensing part 32 of the Hall element 3 deviating from the rotor 5 due to tilting.
[0060] Embodiment 3:
[0061] Please refer to Figures 1 to 8 On the basis of the motor of embodiment 2, the embodiment provides a circulating pump, which comprises: a pump body 6 and the motor of embodiment 2; and a Hall control board assembly arranged at the side end of the coil skeleton 4 away from the pump body 6. This structure can not only improve the compactness of the overall structure of the circulating pump, but also avoid the problem of increased assembly difficulty caused by the interference of the Hall control board assembly when the motor and the pump body 6 are assembled.
