It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0043] The shoe sole metal detection device and security inspection equipment provided by the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0044] refer to Figure 1-Figure 17 The embodiment of the present application provides a sole metal detection device 100, which may include a base assembly 110, a metal detection assembly 120 and a pedal assembly 130. The metal detection assembly 120 may be arranged on the base assembly 110, and the pedal assembly 130 may be arranged above the metal detection assembly 120 and connected to the base assembly 110, that is, the metal detection assembly 120 is arranged in a space enclosed by the pedal assembly 130 and the base assembly 110. The base assembly 110 may support and fix the metal detection assembly 120 and the pedal assembly 130, and the pedal assembly 130 is used for the detected person to step on. After the detected person stands on the pedal assembly 130, the detection member 121 of the metal detection assembly 120 may perform metal detection on the sole of the detected person.

[0045] The metal detection assembly 120 may include a detection member 121, which may detect metal on the sole of the detected person using the principle of electromagnetic induction, and a clearance groove 134 may be provided at the bottom of the pedal assembly 130, and at least a portion of the detection member 121 is located in the clearance groove 134. In this way, the distance between the detection member 121 and the top of the pedal assembly 130 may be reduced, and the distance between the detection member 121 and the sole may be reduced, thereby improving the detection performance of the detection member 121, and thereby improving the detection accuracy of the sole metal detection device 100.

[0046] In an optional embodiment of the present application, Figure 8-Figure 10 As shown, the metal detection assembly 120 may also include a coil fixing seat 122, and the coil fixing seat 122 may be connected to the base assembly 110. The top of the coil fixing seat 122 may be provided with a mounting groove 1221 and an annular boss 1222. The annular boss 1222 may be arranged around the mounting groove 1221. At least a portion of the detection member 121 may be located in the mounting groove 1221, and the detection member 121 may be connected to the annular boss 1222. In this way, since the annular boss 1222 protrudes from the coil fixing seat 122, it is convenient to connect the detection member 121 to the annular boss 1222, thereby facilitating the installation of the detection member 121 on the coil fixing seat 122.

[0047] And, if Figure 3-Figure 6 As shown, at least part of the annular boss 1222 can be located in the clearance groove 134. In this way, it can be ensured that at least part of the detection member 121 is located in the clearance groove 134, thereby reducing the distance between the detection member 121 and the top of the pedal assembly 130.

[0048] In other embodiments, the top of the coil fixing seat 122 may only be provided with a mounting groove 1221, and at least a portion of the detection member 121 is located in the mounting groove 1221. In this way, if the detection member 121 is connected to the coil fixing seat 122, the detection member 121 can be connected to the groove wall or groove bottom of the mounting groove 1221.

[0049] In an optional embodiment, the annular boss 1222 can enclose a limiting groove, the limiting groove is located above the mounting groove 1221 and communicates with the mounting groove 1221, the first part of the detection member 121 can be located in the mounting groove 1221, and the second part of the detection member 121 can be located in the limiting groove. Optionally, the width of the limiting groove here is greater than the width of the mounting groove 1221, and the limiting function can be achieved by the bottom wall of the limiting groove. In this way, the annular boss 1222 can limit the detection member 121 to prevent the detection member 121 from moving relative to the mounting groove 1221.

[0050] In other embodiments, the annular boss 1222 is not disposed on the top of the coil fixing seat 122 , or the space enclosed by the annular boss 1222 does not have a limiting function.

[0051] In an optional embodiment, if Figure 8-Figure 10 As shown, the detection component 121 may include a detection coil 1211 and a coil cover 1212, the detection coil 1211 may be located in the installation groove 1221, and the coil cover 1212 may cover the top of the detection coil 1211, so that the coil cover 1212 may protect the detection coil 1211; and the coil cover 1212 may be connected to the annular boss 1222, and the coil cover 1212 may be located in the limiting groove, so that, on the one hand, it can be avoided that the coil cover 1212 moves and cannot cover the detection coil 1211 during the use of the sole metal detection device 100, and on the other hand, the coil cover 1212 is located in the limiting groove, which is beneficial to reducing the volume of the metal detection assembly 120.

[0052] In addition, if Figure 3 and Figure 4 As shown, the coil cover plate 1212 can be located in the clearance groove 134, or, as shown in FIG. Figure 5 and Figure 6 As shown, at least part of the coil cover plate 1212 and the detection coil 1211 can be located in the clearance groove 134. In this way, the distance between the detection member 121 and the top of the pedal assembly 130 can be reduced.

[0053] In other embodiments, the detection member 121 may only include the detection coil 1211 , the first portion of the detection coil 1211 may be located in the mounting groove 1221 , and the second portion of the detection coil 1211 may be located in the limiting groove.

[0054] In an optional embodiment of the present application, the pedal assembly 130 and the coil holder 122 may be non-metallic structures. In this way, the pedal assembly 130 and the coil holder 122 will not affect the detection performance of the detector 121. Of course, in other embodiments, at least part of the pedal assembly 130 and / or the coil holder 122 may also be a metal structure, so that the strength of the pedal assembly 130 and / or the coil holder 122 can be improved.

[0055] In an optional embodiment of the present application, the shoe sole metal detection device 100 may include at least two detection members 121, the bottom of the pedal assembly 130 may be provided with at least two clearance grooves 134, at least part of each detection member 121 is located in each clearance groove 134 in a one-to-one correspondence, and the top of the pedal assembly 130 may be provided with at least two station indication areas 135, each clearance groove 134 is located below each station indication area 135 in a one-to-one correspondence. In this way, the shoe sole metal detection device 100 can detect two soles of the same detected person or the soles of multiple detected persons at the same time.

[0058] In other embodiments, the sole metal detection device 100 may include only one detection member 121, the bottom of the pedal assembly 130 may be provided with only one clearance groove 134, and the top of the pedal assembly 130 may be provided with a standing position indication area 135. The person being detected may stand on one foot in the standing position indication area 135 during the detection, and the two soles of the person being detected may be detected alternately.

[0059] In an optional embodiment of the present application, the sole metal detection device 100 may further include a control assembly 123, which may be disposed between one group of adjacent detection members 121, and each detection member 121 is electrically connected to the control assembly 123. In this way, it is convenient to connect the detection member 121 with the control assembly 123, and the space between adjacent detection members 121 can be fully utilized, which is conducive to reducing the width or length of the metal detection assembly 120. Further optionally, the control assembly 123 may be centrally disposed between one group of adjacent detection members 121, so as to facilitate the connection between the control assembly 123 and the detection member 121.

[0060] Alternatively, if Fig. 9 and Fig.10 As shown, the shoe sole metal detection device 100 may include two detection members 121 , and the control component 123 is disposed between the two detection members 121 . The control component 123 may be electrically connected to the two detection members 121 , respectively.

[0061] In other embodiments, the control component 123 may be disposed on the side of the detection member 121 , so that a space for disposing the control component 123 needs to be reserved on the coil fixing seat 122 .

[0062] In an optional embodiment, if Figure 8 As shown, the control component 123 may include a control circuit board 1231 and a power adapter 1232 electrically connected to the control circuit board 1231. The control circuit board 1231 may be electrically connected to each detection element 121, and the power adapter 1232 may be used to connect to an external power source to provide electrical energy to the detection coil 1211.

[0063] Optionally, a fixing groove 1223 may also be provided on the top of the coil fixing seat 122, and the fixing groove 1223 may be located between a group of adjacent detection members 121, that is, the fixing groove 1223 may be located between a group of adjacent installation grooves 1221, the control component 123 may be arranged in the fixing groove 1223, and the installation groove 1221 may be provided with a notch connected to the fixing groove 1223, and the notch may be used for a wire connected to the control circuit board 1231 to pass through and then be electrically connected to the detection coil 1211 of the detection member 121.

[0064] Furthermore, a fixing cover plate 1233 may be provided at the notch of the fixing groove 1223, and the fixing cover plate 1233 may close the fixing groove 1223 to close the control assembly 123 in the fixing groove 1223. In this way, the fixing cover plate 1233 may protect the control assembly 123.

[0065] In an optional embodiment of the present application, Figure 2 As shown, a shock absorbing assembly 140 can be arranged between the metal detection assembly 120 and the base assembly 110. The shock absorbing assembly 140 can absorb the vibration generated when the person being detected steps on the pedal assembly 130, thereby preventing the shaking and vibration of the sole metal detection device 100 from affecting the detection element 121.

[0066] Optionally, the shock absorbing assembly 140 may be a shock absorbing foam or a shock absorbing spring, or other forms of shock absorbing components.

[0067] In this embodiment, the metal detection assembly 120 is provided with a shock absorbing assembly 140 between two edges of the metal detection assembly 120 that are opposite to each other along its length direction and the base assembly 110. In this way, the force balance of the metal detection assembly 120 can be ensured.

[0068] In other embodiments, the shock absorbing assembly 140 is not disposed between the metal detecting assembly 120 and the base assembly 110 .

[0069] In an optional embodiment, a gap may be left between the metal detection assembly 120 and the pedal assembly 130 , so as to prevent the pedal assembly 130 from being deformed and squeezing the detection member 121 when the person being detected steps on the pedal assembly 130 , thereby preventing the detection member 121 from being deformed and damaged.

[0070] Here, the height of the gap between the metal detection assembly 120 and the pedal assembly 130 may be about 2 mm.

[0071] Of course, in order to improve the strength of the pedal assembly 130 , the metal detection assembly 120 may be in contact with the pedal assembly 130 , that is, there is no gap between the metal detection assembly 120 and the pedal assembly 130 , so that the metal detection assembly 120 may play a certain supporting role on the pedal assembly 130 .

[0072] In an optional embodiment of the present application, Fig.14 and Fig.15 As shown, the base assembly 110 may include a mounting frame and at least two parallel support rods 115, the pedal assembly 130 may be connected to the mounting frame, the mounting frame may enclose a mounting space 119, the metal detection assembly 120 may be located in the mounting space 119, and each support rod 115 may be located in the mounting space 119 and connected to the mounting frame, and the two opposite edges of the metal detection assembly 120 along its own length direction may be respectively connected to one group of adjacent support rods 115. In this way, the metal detection assembly 120 can be fixed in the mounting space 119, thereby preventing the metal detection assembly 120 from being offset in position and causing the detection performance of the sole metal detection device 100 to be reduced.

[0073] In other embodiments, the base assembly 110 may only include a mounting frame, which encloses an installation space 119 , and the metal detection assembly 120 may be placed in the installation space 119 . In this way, the metal detection assembly 120 is not fixedly connected to the base assembly 110 .

[0074] Alternatively, if Fig.14 As shown, a groove 1151 may be provided on the support rod 115 , the shock absorbing assembly 140 may be disposed in the groove 1151 , and the top end of the shock absorbing assembly 140 may contact the metal detecting assembly 120 .

[0075] In addition, in order to prevent the metal detection assembly 120 from shaking or misalignment, the support rod 115 is connected to the coil fixing seat 122 of the metal detection assembly 120 via a positioning pin 118 .

[0076] In an optional embodiment, the support rods 115 may be slidably connected or detachably connected to the mounting frame so that two adjacent support rods 115 may be moved closer to or farther from each other. In this way, the positions of the support rods 115 may be adjusted according to the size of the metal detection assembly 120, so that the base assembly 110 may be adapted to metal detection assemblies 120 of different sizes.

[0077] In other embodiments, the support rod 115 is fixedly connected to the installation frame, and the position of the support rod 115 remains fixed.

[0079] Here, both ends of each support rod 115 may be connected to the first fixing rod 111 and the second fixing rod 112 , respectively.

[0080] Furthermore, the third fixing rod 113 and the fourth fixing rod 114 can be spaced apart from the adjacent support rod 115, and both the third fixing rod 113 and the fourth fixing rod 114 can be metal rods. In this way, the strength of the mounting frame can be improved, and since the third fixing rod 113 and the fourth fixing rod 114 are spaced apart from the adjacent support rod 115, the interference or influence of the metal rod on the detection of the detection member 121 can be reduced.

[0081] In other embodiments, the first fixing rod 111 , the second fixing rod 112 , the third fixing rod 113 , and the fourth fixing rod 114 are all metal rods.

[0082] Optionally, the first fixing rod 111 and the second fixing rod 112 can be made of POM (Polyformaldehyde) material. Since POM has high strength, rigidity, good elasticity, and good wear resistance, the strength of the first fixing rod 111 and the second fixing rod 112 can be higher, thereby improving the strength of the installation frame.

[0083] In some embodiments, a wire threading groove and a wire routing groove may be provided on the installation frame, and the wire threading groove is connected with the wire routing groove. The power cord may pass through the wire threading groove and the wire routing groove in sequence and then be electrically connected to the control component 123.

Both ends of the first reinforcing rod 116 and both ends of the second reinforcing rod 117 may be respectively connected to a group of adjacent support rods 115. The two edges of the metal detection assembly 120 along its own width direction are respectively located above the first reinforcing rod 116 and the second reinforcing rod 117 and are respectively in contact with the first reinforcing rod 116 and the second reinforcing rod 117. In this way, the first reinforcing rod 116 and the second reinforcing rod 117 can support the metal detection assembly 120.
