In addition, the cover plate 12 can be made of plastic, so that the weight of the cover plate can be reduced, and the user experience is better.
In one embodiment, referring to fig. 5, the cover plate 12 is provided with a first mounting hole 121 matching with the connecting member 13; the connecting piece 13 comprises a connecting part 131 and a rotating buckle 132, and the rotating buckle 132 is movably connected with the connecting part 131; with the rotary catch 132 in the first position, the rotary catch 132 can pass through the first mounting hole 121; with the rotary catch 132 in the second position, the rotary catch 132 cannot pass through the first mounting hole 121.
In one embodiment, the first mounting hole 121 has a first size and a second size, the first size being smaller than the second size; the maximum size of the rotary catch 132 is greater than the first size and less than the second size; the minimum size of the rotary buckle is smaller than the first size.
Taking the cover plate shown in fig. 4 as an example, two first mounting holes 121 are opened in the cover plate 12. The first mounting hole 121 has an oblong shape, a first size of the first mounting hole 121, i.e., a width of the first mounting hole 121, and a second size of the first mounting hole 121, i.e., a length of the first mounting hole 121. Accordingly, taking the connector shown in fig. 5 as an example, the shape of the rotary catch 132 of the connector 13 is a diamond. Wherein a minimum dimension (one diagonal of the diamond shape) of the rotary catch 132 is smaller than a first dimension (width of the first mounting hole 121) of the first mounting hole 121, a maximum dimension (the other diagonal of the diamond shape) of the rotary catch 132 is larger than the first dimension (width of the first mounting hole 121) of the first mounting hole 121, and a maximum dimension (the other diagonal of the diamond shape) of the rotary catch 132 is smaller than a second dimension (length of the first mounting hole 121) of the first mounting hole 121. Thus, when the rotary latch 132 rotates to the first position, that is, the maximum size of the rotary latch 132 is parallel to the length direction of the first mounting hole 121, at this time, the rotary latch 132 can pass through the first mounting hole 121; when the rotary latch 132 rotates to the second position, that is, the maximum size of the rotary latch 132 is parallel to the width direction of the first mounting hole 121, the rotary latch 132 cannot pass through the first mounting hole 121, and the rotary latch 132 can latch the cover plate 12 on the positioning chassis 11.
It is understood herein that the first mounting hole may have an oblong, oval, diamond or rectangular shape, and the rotary catch may have an oblong, oval, diamond or rectangular shape. In addition, the shape of the first mounting hole and the shape of the rotary buckle can be the same or different. The shape of the first mounting hole and the shape of the rotary buckle are not limited in the embodiments of the present disclosure.
The operation of the coupling will now be described by way of example with reference to fig. 4 and 5. One end of the connection part 131 is connected with the rotary buckle 132, and the other end of the connection part 131 is provided with a thread. When the cover plate 12 and the positioning chassis 11 are connected by the connecting member 13, the connecting portion 131 passes through the first mounting hole 121 of the cover plate 12 and is connected to the positioning chassis 11 in a fitting manner. Meanwhile, the rotary catch 132 is located on a side of the cover plate 12 facing away from the positioning chassis 11, that is, the rotary catch 132 is located outside the first mounting hole 121. At this time, the rotating buckle 132 can be rotated to clamp the cover plate 12 on the positioning chassis 11. For example, when the rotary latch 132 is rotated to the first position, the longer diagonal line of the rotary latch 132 extends along the width direction of the first mounting hole 121, and the length of the longer diagonal line of the rotary latch 132 is greater than the width of the first mounting hole 121, at this time, the rotary latch 132 is located outside the first mounting hole 121, and the rotary latch 132 cannot pass through the first mounting hole, so that the cover plate 12 is fixed on the positioning chassis 11 by the rotary latch 132. For example, when the rotary latch 132 is rotated to the second position, the shorter diagonal line of the rotary latch 132 extends along the width direction of the first mounting hole 121, the length of the shorter diagonal line of the rotary latch 132 is smaller than the width of the first mounting hole 121, the longer diagonal line of the rotary latch 132 extends along the length direction of the first mounting hole 121, and the length of the longer diagonal line of the rotary latch 132 is smaller than the width of the first mounting hole 121, at this time, the rotary latch 132 can pass through the first mounting hole, so as to achieve the detachment of the cover plate.
In this embodiment, the connecting piece includes connecting portion and rotatory buckle, and rotatory buckle rotates with connecting portion to be connected, rotates when rotatory buckle rotates to the primary importance, and the first mounting hole of rotatory buckle accessible, when rotatory buckle rotates to the second place, and rotatory buckle can not pass through first mounting hole, like this, through rotating rotatory buckle, can realize the fixed of apron and dismantle simple structure, convenient operation.
In this embodiment, the magnetism detection mechanism 20 is used for detecting the magnetism of the first magnetic attraction piece after being magnetized and the magnetic pole direction of the first magnetic attraction piece. The magnetic detection means 20 will be explained below.
For example, referring to fig. 6 and 7, a positioning groove 211 matched with the positioning chassis 11 is formed in the base 21, a plurality of detection holes 212 are formed in the positioning groove 211, the plurality of detection holes 212 and the plurality of accommodating grooves 111 are arranged in a one-to-one correspondence manner, the detection hole 121 is used for placing a detection assembly, and the detection assembly is used for detecting the magnetism and the magnetic pole direction of the first magnetic attraction piece in the accommodating groove. Optionally, as shown in fig. 3 and fig. 6, the plurality of receiving grooves 111 on the positioning chassis 11 are annularly arranged, the plurality of detecting holes 212 on the base 21 are also annularly arranged, and one receiving groove 111 and one detecting hole 212 are correspondingly arranged, that is, when the positioning mechanism 10 is placed in the positioning groove 211 of the base 21, the receiving groove 111 is located above the detecting hole 212, so that the detecting component is located below the first magnetic component to be detected, so as to detect the magnetism and the magnetic pole direction of the first magnetic component in the receiving groove. It should be noted here that, the positioning mechanism 10 is connected to the base 21 in a clamping manner, which facilitates installation of the positioning mechanism, and in the detection process, the positioning mechanism can be prevented from loosening, thereby improving the detection accuracy.
With continued reference to fig. 6, the detecting assembly includes a sensing post 22 and a proximity sensor 23, the sensing post 22 and the proximity sensor 23 are disposed in the detecting hole 212, and the sensing post 22 is located above the proximity sensor. The inductive column 22 has magnetic conductivity, and the inductive column 22 can move up and down along the axial direction of the detection hole 212 under the action of magnetic force. The proximity sensor 23 is used to detect whether the sensing post 22 is approaching, i.e., whether the sensing post 22 is moving without being affected by the magnetic force.
Optionally, the diameter of the sensing post 22 is smaller than the diameter of the sensing hole 212. Illustratively, the diameter of the inductive column 22 may be close to the diameter of the first magnetically attractive element to be detected. Like this, can guarantee that the response post is followed the axial displacement of inspection hole under the effect of the magnetic force of first magnetism piece of inhaling.
Optionally, the distance between the proximity sensor 23 and the positioning chassis 11 is greater than the height of the sensing column 22, that is, in a case where the positioning mechanism is placed in the magnetic detection mechanism, there is a certain gap between the proximity sensor 23 and the positioning chassis 11, so that the sensing column 22 can move along the axial direction of the detection hole, and thus, the detection of the magnetism and the magnetic pole direction of the first magnetic attraction piece can be realized by detecting the position of the sensing column through the proximity sensor.
It should be noted that the inductive column 22 may be made of a material with magnetic conductivity, for example, the material of the inductive column 22 may be stainless iron, and the material of the inductive column is not limited in the embodiment of the disclosure.
Alternatively, the proximity sensor may be a capacitive proximity sensor, an inductive proximity sensor, or an optoelectronic proximity sensor, among others. The disclosed embodiments do not limit the type and model of the proximity sensor.
In this embodiment, since the induction column 22 has magnetic permeability, when the first magnetic attraction piece placed in the positioning mechanism 10 is successfully magnetized, that is, the first magnetic attraction piece has magnetism, the first magnetic attraction piece in the accommodating groove can generate attraction force to the induction column 22, and the induction column 22 is attracted by the first magnetic attraction piece to move upwards, and is far away from the proximity sensor below. When the first magnetic attraction piece placed in the positioning mechanism 10 is magnetized in a leakage manner, that is, the first magnetic attraction piece does not have magnetism, the first magnetic attraction piece in the accommodating groove does not generate attraction force on the induction column 22, and the induction column 22 is close to the proximity sensor 23 under the action of gravity. Based on this, whether the first magnetism piece of inhaling in the positioning mechanism has magnetism can be detected according to the signal of proximity sensor output.
The working principle of the detection assembly is explained by taking fig. 8-10 as an example. As shown in fig. 8, when the first magnetic attraction member is not magnetized, the sensing rod 22 is not lifted, i.e. the proximity sensor 23 can detect the approach of the sensing rod 22. As shown in fig. 9, after the first magnetic attraction member is magnetized, the sensing column 22 is lifted up, that is, the sensing column 22 receives the magnetic force of the first magnetic attraction member, attracts the first magnetic attraction member, and moves upward, which indicates that all the three first magnetic attraction members are magnetized successfully. As shown in fig. 10, after the first magnetic member is magnetized, if the sensing pillars 22 are not all lifted, for example, the sensing pillar 22 in the middle is not lifted, that is, the first magnetic member in the middle is not magnetized. Therefore, the magnetizing condition of each corresponding first magnetic attraction piece can be judged according to the detection result output by each detection assembly.
In one embodiment, the weight of the sensing column 22 can be set according to the magnitude of the magnetic force of the first magnetic member to be detected.
It can be understood that when the magnetic force generated by the first magnetic attraction member is greater than the gravity of the sensing column 22, the sensing column 22 can move upward under the action of the magnetic force of the first magnetic attraction member. Based on this, the weight of the induction column 22 can be designed according to the magnitude of the magnetic force of the first magnetic attraction piece to be magnetized, so as to ensure the accuracy of detection.

In this embodiment, the second magnetic element can be used to detect the magnetic pole direction of the first magnetic element to be magnetized, i.e. to detect the polarity of the first magnetic element to be magnetized. For example, assume that the magnetic pole direction of the first magnetic attraction member after being magnetized is N-pole downward and S-pole upward. In contrast, the magnetic pole direction of the second magnetic member disposed on the upper portion of the induction column 22 is set to be S-pole upward and N-pole downward. In the detection process, if the sensing column 22 is attracted and lifted upwards by the first magnetic member, it indicates that the first magnetic member and the sensing column are attracted to each other, i.e. the magnetic pole direction of the first magnetic member is N-pole downward and S-pole upward. If the sensing column 22 is not attracted by the first magnetic member to be lifted upwards, the first magnetic member and the sensing column repel each other, i.e. the magnetic pole direction of the first magnetic member is N-pole up and S-pole down.
