When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0031] like Figures 1 to 6 As shown, an induction structure includes an induction power supply 2 and an induction head 1; the induction power supply 2 is provided with an induction power supply magnetic part 21, and the induction head 1 is provided with an induction head magnetic part 11 corresponding to the induction power supply magnetic part 21, and the induction head 1 can be installed on the induction power supply 2 through the induction power supply magnetic part 21 and the induction head magnetic part 11; and also includes a conductive structure 3, the conductive structure 3 includes a first conductive part 22 and a second conductive part 12, the first conductive part 22 is provided on a side of the induction power supply 2 close to the induction head 1, and the second conductive part 12 is provided on a side of the induction head 1 close to the induction power supply 2, when the induction head 1 is installed on the induction power supply 2, the first conductive part 22 and the second conductive part 12 are in contact with each other.

[0032] When assembling the induction structure, the induction power supply 2 is installed on the device served by the induction structure, and then the induction head 1 is adsorbed on the induction power supply by the induction power supply magnetic part 21 and the induction head magnetic part 11 using the principle of magnetic attraction, and then adaptive adjustments are made as needed so that the first conductive part 22 and the second conductive part 12 are in contact with each other, so that the induction power supply 2 can electrically control the induction head 1, and the installation of the induction head 1 on the induction power supply 2 is completed. When the induction element in the induction structure fails and needs to be repaired or replaced, it is only necessary to remove the induction head 1 from the induction power supply 2, and there is no need to disassemble the entire induction structure, which facilitates the repair or replacement of the induction element 15, is conducive to improving the efficiency of induction structure repair, and optimizing the user experience.

[0033] In some specific embodiments, the induction power supply magnetic component 21 and the induction head magnetic component 11 are both magnets, and the polarity of the side of the induction power supply magnetic component 21 facing the induction head 1 is opposite to the polarity of the side of the induction head magnetic component 11 facing the induction power supply 2 .

[0034] Specifically, the magnetic body is a magnet. The magnet provided on the induction power supply 2 has its N pole facing the induction head 1, and the magnet provided on the induction head 1 has its S pole facing the induction power supply 2; or, the magnet provided on the induction power supply 2 has its S pole facing the induction head 1, and the magnet provided on the induction head 1 has its N pole facing the induction power supply 2. The induction head 1 is adsorbed on the induction power supply 2 by utilizing the principle that opposite poles of magnets attract each other.

[0035] In some specific embodiments, the induction power supply magnetic component 21 is a magnet, and the induction head magnetic component 11 is a magnetic material, or the induction head magnetic component 11 is a magnet, and the induction power supply magnetic component 21 is a magnetic material.

[0036] According to the definition, a magnet is a substance or material that can generate a magnetic field, and a magnetic substance is a substance that can generate magnetism under the action of a magnetic field. Specifically, the magnet in this embodiment is a magnet, and the magnetic substance is an iron sheet. By using the principle that a magnetic substance can be magnetized and attracted by a magnet, the magnet attracts the iron sheet, so that the iron sheet is adsorbed on the magnet, thereby enabling the induction head 1 to be adsorbed on the induction power supply 2.

[0037] In some specific embodiments, reference Figures 1 to 3 ,as well as Figure 5 and Figure 6 The inductive power supply 2 includes a power supply electronic control module 241, and at least two first conductive members 22 are provided on the inductive power supply 2, and the two first conductive members 22 are respectively a first positive conductive member 221 and a first negative conductive member 222, and the first positive conductive member 221 and the first negative conductive member 222 are respectively connected to the positive electrode and the negative electrode of the power supply electronic control module 241; the inductive head 1 includes an inductive electronic control module 151, and at least two second conductive members 12 are provided on the inductive head 1, and the two second conductive members 12 are respectively a second positive conductive member 121 and a second negative conductive member 122, and the second positive conductive member 121 and the second negative conductive member 122 are respectively connected to the positive electrode and the negative electrode of the inductive electronic control module 151; the first positive conductive member 221 and the second positive conductive member 121 are in corresponding positions, and the first negative conductive member 222 and the second negative conductive member 122 are in corresponding positions.

[0038] At least two induction power supply magnetic parts 21 are provided on the induction power supply 2, and the two induction power supply magnetic parts 21 are respectively a first induction power supply magnetic part 211 and a second induction power supply magnetic part 212. The N pole of the first induction power supply magnetic part 211 faces the induction head 1, and the S pole of the second induction power supply magnetic part 212 faces the induction head 1; at least two induction head magnetic parts 11 are provided on the induction head 1, and the two induction head magnetic parts 11 are respectively a first induction head magnetic part 111 and a second induction head magnetic part 112. The S pole of the first induction head magnetic part 111 faces the induction power supply 2, and the N pole of the second induction head magnetic part 112 faces the induction power supply 2; the first induction power supply magnetic part 211 corresponds to the first induction head magnetic part 111 in position, and the second induction power supply magnetic part 212 corresponds to the second induction head magnetic part 112 in position.

[0039] Specifically, in this embodiment, the induction power supply magnetic component 21 and the induction head magnetic component 11 are both magnets. Since the N pole of the first induction power supply magnetic component 211 faces the induction head 1, the S pole of the second induction power supply magnetic component 212 faces the induction head 1, the S pole of the first induction head magnetic component 111 faces the induction power supply 2, and the N pole of the second induction head magnetic component 112 faces the induction power supply 2, during installation, only when the first induction power supply magnetic component 211 and the first induction head magnetic component 111 are in corresponding positions, and the second induction power supply magnetic component 212 and the second induction head magnetic component 112 are in corresponding positions, the induction head 1 can be adsorbed on the induction power supply 2, the first positive electrode conductive component 221 and the second positive electrode conductive component 121 are in corresponding positions, and the first negative electrode conductive component 222 and the second negative electrode conductive component 122 are in corresponding positions, and the positive and negative poles between the induction head 1 and the induction power supply 2 are correctly connected.

[0040] During installation, the induction power supply magnetic part 21 and the induction head magnetic part 11 set as above form a "fool-proof structure" to ensure that the positive and negative poles between the induction head 1 and the induction power supply 2 can be correctly connected, which is beneficial to improve the efficiency of installing the induction head 1 on the induction power supply 2, ensure the normal operation of the induction structure, and extend the service life of the induction structure.

[0041] Furthermore, the surface of the induction power supply 2 near the induction head 1 is circular, and the two induction power supply magnetic parts 21 and the two first conductive parts 22 are evenly arranged and staggered around the axis of the surface; correspondingly, the surface of the induction head 1 near the induction power supply 2 is circular, and the two induction head magnetic parts 11 and the two second guide parts 12 are evenly arranged and staggered around the axis of the surface. With such an arrangement, when the induction head 1 is adsorbed, the attraction force on each part of it is relatively even, which is conducive to more stable fixing on the induction power supply 2.

[0042] In some other embodiments, the surface of the induction power supply 2 close to the induction head 1 is circular, and an induction power supply magnetic part 21 is provided on the induction power supply 2, and the induction power supply magnetic part 21 is located on the circumferential side of the axis of the surface; correspondingly, the surface of the induction head 1 close to the induction power supply 2 is circular, and an induction head magnetic part 11 is provided on the induction head 1, and the induction head magnetic part 11 is located on the circumferential side of the axis of the surface. Such an arrangement also has an "anti-fool" effect.

[0043] In some other embodiments, the inductive power supply 2 is provided with more than two inductive power supply magnetic parts 21, and correspondingly, the inductive head 1 is provided with more than two inductive head magnetic parts 11, as long as a "fool-proof structure" can be formed to ensure that the positive and negative poles between the inductive head 1 and the inductive power supply 2 can be correctly connected.

[0044] In some specific embodiments, reference Figures 2 to 4 The induction head 1 includes a second shell 13, and an induction element 15 on which an induction mounting plate 14 is arranged on the inner side of the second shell 13, and the second conductive member 12 is communicatively connected with the induction element 15; the second conductive member 12 includes a conductive column 123 and a spring 124, and a guide column 141 is arranged on the induction mounting plate 14, and the spring 124 and at least part of the conductive column 123 are arranged in the guide column 141, one end of the spring 124 is connected to the conductive column 123, and the other end is connected to the bottom of the guide column 141, and the conductive column 123 can move along the extension direction of the guide column 141; a conductive hole 132 is arranged at one end of the second shell 13 close to the induction power supply 2, and the conductive hole 132 corresponds to the position of the conductive column 123, and the conductive column 123 is penetrated in the conductive hole 132 and can extend out of the conductive hole 132.

[0045] Before the induction head 1 is installed on the induction power supply 2, the conductive column 123 extends out of the conductive hole 132; after the induction head 1 is installed on the induction power supply 2, the conductive column 123 is pressed on the first conductive member 22 and retracted into the conductive hole 132, squeezing the spring 124. Correspondingly, the spring 124 continuously outputs a supporting force to the conductive column 123, so that the conductive column 123 can be in close contact with the first conductive member 22 to ensure the conductive effect.

[0046] In some other embodiments, the second conductive member 12 is in the form of a sheet, plate or other forms, or the second conductive member 12 is a structure composed of multiple components, as long as it can contact the first conductive member 22 after the induction head 1 is installed on the induction power supply 2.

[0047] In some specific embodiments, reference Figure 5The inductive power supply 2 includes a first shell 23, an electric control element 24 is provided on the inner side of the first shell 23, and the first conductive member 22 is communicatively connected with the electric control element 24; the first conductive member 22 is in the shape of a sheet or a plate, and the first conductive member 22 is embedded in the first shell 23, and the surface of the first conductive member 22 close to the inductive head 1 is flush with the surface of the first shell 23 close to the inductive head 1, or the surface of the first conductive member 22 close to the inductive head 1 is recessed relative to the surface of the first shell 23 close to the inductive head 1.

[0048] In some other embodiments, the first conductive member 22 includes a conductive column, or the first conductive member 22 has other shapes, as long as it can contact the second conductive member 12 after the induction head 1 is installed on the induction power supply 2 .

[0049] This embodiment also provides a lamp, referring to Figure 7 and Figure 8 , including the above-mentioned sensing structure.

[0050] In some specific embodiments, reference Figure 7 and Figure 8 The lamp also includes a lamp holder 4 and a lamp cover 5. The induction power supply 2 is arranged in a cavity enclosed by the lamp holder 4 and the lamp cover 5. The lamp cover 5 is provided with a mounting hole 51. The mounting hole 51 corresponds to the position of the induction power supply 2. The induction head 1 partially passes through the mounting hole 51 and is installed on the induction power supply 2. The top 16 of the induction head 1 protrudes from the lamp cover 5.

[0051] Due to the requirement of induction sensitivity, after the induction head 1 is mounted on the induction power supply 2 , the top 16 of the induction head 1 protrudes from the lamp cover 5 .

[0052] When the specifications of the lamp holder 4 and / or the lamp cover 5 of the lamp change, so that the height of the cavity increases or decreases, it is only necessary to replace the induction power supply 2 of the appropriate height. As long as the induction head 1 is installed on the induction power supply 2, its head 16 can protrude from the lamp cover 5, which is conducive to expanding the adaptation range of the induction structure and reducing production costs.

[0053] In some specific embodiments, reference Figure 7 and Figure 8 An induction head limiting member 131 is provided around the induction head 1, and the induction head limiting member 131 is located in the cavity. An induction head limiting portion 52 is provided around the mounting hole 51, and the positions of the induction head limiting member 131 and the induction head limiting portion 52 correspond to each other, so as to limit the induction head 1 from being away from the induction power supply 2.

[0054] Specifically, the induction head stopper 131 is provided with a guide slope, which extends in the direction away from the induction head 1 in the arrangement direction from the induction power supply 2 to the induction head 1, so that the induction head 1 can smoothly pass through the mounting hole 51. The induction head stopper 52 is an annular portion provided on the lamp cover 5 around the mounting hole 51. If an accident occurs, when the induction head 1 is separated from the induction power supply 2 and falls down, the induction head 1 will be clamped on the induction head stopper 52 through the induction head stopper 131 to avoid hitting the user.

[0055] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
