[0034] The present utility model provides a heel detection assembly.

[0035] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, the heel detection assembly 100 includes a mounting member 110 and an imaging module 120. The mounting member 110 has a first end 111 and a second end 112 which are oppositely arranged. A connecting portion 113 for connecting with the sole detection assembly 210 is provided at the first end 111 of the mounting member 110. A limiting groove 111a is formed at the second end 112 of the mounting member 110. The bottom of the imaging module 120 is limit-mounted in the limiting groove 111a and abuts against the groove wall. The imaging module 120 includes a lens 121 for shooting. The lens 121 protrudes outside the limiting groove 111a. An imaging interval is provided between the first end 111 and the second end 112. The optical axis of the lens 121 faces the imaging interval and is inclined upward, that is, the optical axis of the lens 121 forms an angle with the upper surface of the mounting member 110, so as to perform point-position shooting on the calcaneus of the foot to be measured on the sole detection assembly 210 outside the imaging interval.

[0036] It can be understood that after the mounting member 110 is connected to the plantar detection component 210 through the connecting portion 113, the camera module 120 on the mounting member 110 can be positioned and connected to the plantar detection component 210. When a person stands on the plantar detection component 210 with their back to the heel detection component 100, the plantar detection component 210 can detect conditions such as inversion and eversion of the sole. Since there is a certain distance between the first end portion 111 and the second end portion 112, the upwardly inclined lens 121 can clearly capture an image of the human heel portion through the imaging interval. After obtaining the image, it can be transmitted to the computer terminal, and the set points of the heel can be automatically recognized through artificial intelligence technology, or the eversion angle of the heel can be measured by manually marking points. Combining the data such as the inversion and eversion of the sole measured by the plantar detection component 210, a comprehensive detection of the human foot bone structure can be carried out in all directions to obtain more accurate and comprehensive data, so that professionals can give reasonable correction plans.

[0037] In one embodiment, the connecting portion 113 is recessed in a direction away from the plantar detection component 210 to form a mounting notch 113a, and one side of the plantar detection component 210 is limited and abutted within the mounting notch 113a.

[0038] As Figure 1 and Figure 6 shown, in an embodiment of the present utility model, the mounting member 110 is an overall plate-like structure. The connecting portion 113 extends from the first end portion 111 of the mounting member 110 in a direction away from the second end portion 112. The middle position of the connecting portion 113 is recessed in a direction close to the first end portion 111 to form a mounting notch 113a. The outer shape of the plantar detection component 210 is also a plate-like structure. The shape of the mounting notch 113a matches the outer shape of the plantar detection component 210. One side edge of the plantar detection component 210 abuts against the first end portion 111 of the mounting member 110, and the two adjacent sides of this side edge are respectively limited and abutted against the connecting portions 113 at both ends of the mounting member 110. The camera module 120 can be positioned and connected to the plantar detection component 210 through the mounting member 110, so that the lens 121 has a suitable photographing position and shooting angle, ensuring the clarity of the photographed image of the heel portion.

[0039] It can be understood that in this embodiment, through the positioning of the connecting portion 113, it is convenient for the heel detection component 100 and the plantar detection component 210 to be spliced and separated. During use, the assembly is simple and fast, and when stored, the separation does not occupy space, with high practicality. It should be noted that in some other embodiments of the present utility model, the connecting portion 113 can adopt structures such as buckles and slide rails to dock with the plantar detection component 210, as long as the positioning of the camera module 120 can be achieved, and specific limitations are not made here.

[0040] In one embodiment, the camera module 120 further includes a fixing block 122, a circuit board 123, and a light-transmitting plate 124. The fixing block 122 is connected to the mounting member 110. A receiving groove 122a is provided on the side of the fixing block 122 facing the imaging area. The light-transmitting plate 124 covers the opening of the receiving groove 122a. The circuit board 123 is disposed in the receiving groove 122a. The lens 121 is provided on the circuit board 123 and is aligned with the light-transmitting plate 124.

[0041] As Figures 1 to 3 shown, in an embodiment of the present invention, the camera module 120 includes a fixing block 122, a circuit board 123, and a light-transmitting plate 124. The shape of the fixing block 122 fits the shape of the limiting groove 111a on the mounting member 110, and the top of the fixing block 122 protrudes from the limiting groove 111a. A receiving groove 122a is formed by the side of the fixing block 122 facing the imaging area recessing away from the first end 111. The circuit board 123 is fixed in the receiving groove 122a. The lens 121 is installed on the side of the circuit board 123 facing the imaging area. The light-transmitting plate 124 is covered on the opening of the receiving groove 122a. External light can reach the lens 121 through the light-transmitting plate 124. The lower end of the fixing block 122 is attached to the bottom wall of the limiting groove 111a. The light-transmitting plate 124 covering the opening makes the receiving groove 122a form a relatively enclosed space to protect the circuit board 123 and the lens 121 in the receiving groove 122a. It should be noted that the light-transmitting plate 124 can be a glass plate or a transparent acrylic plate, etc., which can be selected according to requirements to ensure that the lens 121 can clearly capture the heel part of the human body, and no specific limitation is made here.

[0042] In one embodiment, an air flow channel 122b is further provided on the fixing block 122; a first through hole 110a is provided through the mounting member 110, and a second through hole 124a is provided through the light-transmitting plate 124. The second through hole 124a, the receiving groove 122a, the air flow channel 122b, and the first through hole 110a are sequentially connected;

[0043] And / or, the air flow channel 122b communicates with the bottom wall of the receiving groove 122a. A boss 1221 is provided at a position on the bottom wall of the receiving groove 122a away from the air flow channel 122b. The side of the circuit board 123 facing away from the lens 121 abuts against the boss 1221, so as to form a gap between the circuit board 123 and the bottom wall of the receiving groove 122a.

[0044] As Figures 3 to 5As shown in the figure, in an embodiment of the present utility model, an air flow channel 122b is provided at the bottom of the fixed block 122, and a first through hole 110a is penetratingly provided at the bottom wall of the limiting groove 111a of the mounting member 110. The air flow channel 122b communicates the accommodating groove 122a with the through hole, and the number of the first through holes 110a is two. The lens 121 generates heat during operation, and external air can enter the accommodating groove 122a along the air flow channel 122b from the two first through holes 110a to dissipate heat from the lens 121. Further, a second through hole 124a is provided at the upper end of the light-transmitting plate 124, and the second through hole 124a communicates with the accommodating groove 122a. The heat generated by the lens 121 causes the gas in the accommodating groove 122a to heat up and flow upward, that is, the air in the accommodating groove 122a can carry heat and flow out to the outside through the second through hole 124a. Cooperating with the air intake of the air flow channel 122b and the first through hole 110a, heat dissipation of the circuit board 123 and the lens 121 can be achieved, and the components in the camera module 120 can be prevented from being damaged due to accumulated heat inside the camera module 120.

[0045] Please refer to Figure 3 , further, in order to improve the heat dissipation effect, convex platforms 1221 are provided at both ends of the bottom wall of the accommodating groove 122a away from the air flow channel 122b. Threaded holes are provided on the convex platforms 1221. Screws are used to pass through the circuit board 123 and screw into the threaded holes to fix both ends of the side of the circuit board 123 facing away from the lens 121 on the two convex platforms 1221. The surface of the convex platform 1221 has a certain distance from the bottom wall of the accommodating groove 122a, so that a gap is formed between the circuit board 123 and the bottom wall of the accommodating groove 122a, which can be used for air flow to pass through and take away heat, further improving the heat dissipation effect of the camera module 120. The surface of the convex platform 1221 in contact with the circuit board 123 is set as an inclined surface, which is convenient for adjusting the shooting direction of the lens 121. The following specifically describes this structure.

[0046] In an embodiment, the heel detection component 100 further includes a cover plate 130. The cover plate 130 is provided on the side of the mounting member 110 away from the imaging interval. The cover plate 130 and the mounting member 110 enclose an accommodating cavity 130a, and the accommodating cavity 130a is used for installing a splitter. A wire routing groove 110b extending from the accommodating cavity 130a to the camera module 120 is provided on the mounting member 110 for the camera module 120 to connect to the splitter and externally connect devices through the splitter.

[0047] As Figure 2As shown, in an embodiment of the present utility model, the heel detection component 100 further includes a cover plate 130 disposed on the mounting member 110. The cover plate 130 is located at a position on the mounting member 110 away from the imaging interval to prevent the lens 121 from being blocked. A receiving cavity 130a is formed by enclosing the upper surface of the cover plate 130 and the mounting member 110. The receiving cavity 130a is used for placing a splitter. The mounting member 110 is further provided with a wiring groove 110b communicating from the receiving cavity 130a to the limiting groove 111a. One end of the wiring is connected to the circuit board 123 of the imaging module 120, and the other end of the wiring extends along the wiring groove 110b into the receiving cavity 130a to connect to the splitter. The splitter is connected to the sole detection component 210 and the computer through two wirings respectively. One wiring is used to transmit the photos taken by the lens 121 to the computer, and the other wiring is used to synchronize the measurements of the sole detection component 210 and the heel detection component 100, which can improve the detection efficiency. The heel detection component 100 is further provided with a stop strip 140. The stop strip 140 is used to block the wiring groove 110b extending from the limiting groove 111a to the cover plate 130, so as to keep the upper surface of the mounting member 110 flat and improve the overall aesthetics.

[0048] In one embodiment, the cover plate 130 is provided with a flange 131. The flange 131 extends along the second end 112 of the mounting member 110 to the side, and a wire passing hole 131a communicating the receiving cavity 130a with the outside is penetrated through the flange 131.

[0049] As Figure 2 and Figure 6 As shown, in an embodiment of the present utility model, the cover plate 130 is provided with a flange 131. The flange 131 extends from the second end 112 of the mounting member 110 through the side to the direction close to the first end 111. A wire passing hole 131a is penetrated through the position of the flange 131 close to the receiving cavity 130a. Two wirings on the splitter respectively pass through the two wire passing holes 131a to connect to the sole detection component 210 and the computer. It can be understood that the wire passing hole 131a and the interface 211 of the sole detection component 210 are arranged on the same side, which can keep the appearance of the two coordinated and consistent, and at the same time facilitate wiring management. Further, in order to prevent the wiring from being worn by the flange 131, a collar 132 is further provided at the wire passing hole 131a. The collar 132 can be made of materials such as plastic or rubber, and no specific limitation is made here.

[0050] In one embodiment, the distance between the lens 121 and the first end 111 is L1, and the distance L1 satisfies: 200 ≤ L1 ≤ 400 mm;

[0051] And / or, an angle α is formed between the optical axis of the lens 121 and the upper surface of the mounting member 110, and the angle α satisfies: 31.5° ≤ α ≤ 41.5°.

[0052] AsFigure 4 As shown, in an embodiment of the present utility model, in order to improve the clarity of photo shooting, the distance between the lens 121 and the first end 111 of the mounting member 110 is defined as L1, and L1 is greater than or equal to 200 mm and less than or equal to 400 mm, that is, L1 can be 200 mm, 300 mm or 400 mm, or any value within the above range; and the angle between the optical axis of the lens 121 and the upper surface of the mounting member 110 is α, and this angle α is greater than or equal to 31.5° and less than or equal to 41.5°, that is, L1 can be 31.5°, 36.5° or 41.5°, or any value within the above range. The distance L1 and the angle α can be adjusted according to actual needs and are not specifically limited herein.

[0053] In addition, a plurality of circular grooves 110c are provided at the bottom of the mounting member 110 for pasting the foot pads 150. In this embodiment, the number of foot pads 150 is 4 and they are respectively arranged at the four corners of the mounting member 110. In some other embodiments of the present utility model, the number of foot pads 150 is not specifically limited and can be set according to actual situations.

[0054] The present utility model also proposes a plantar pressure device accessory 200, which includes a plantar detection component 210 and a heel detection component 100. The specific structure of the heel detection component 100 refers to the above embodiment. Since this plantar pressure device accessory 200 adopts all the technical solutions of the above all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments and will not be elaborated herein one by one. Among them, the plantar measurement component is arranged on the side of the first end 111 of the heel detection component 100 away from the imaging module 120, so as to form an imaging interval between the imaging module 120 and the plantar detection component 210, facilitating the lens 121 to take pictures.

At least a part of the sole detection component 210 is limited and abutted within the mounting notch 113a. The first end portion 111 is used to abut against the side of the sole detection component 210, so as to fix the distance between the camera module 120 and the sole detection component 210. The two connecting portions 113 respectively abut against two adjacent sides of the side of the sole detection component 210 to limit the lateral movement of the sole detection component 210 along the first end portion 111, and avoid incorrect imaging of the foot to be measured.

[0057] In an embodiment, a standing area 210a is provided on the sole detection component 210. A sensor is provided below the standing area 210a inside the sole detection component 210. The camera module 120 is disposed on the side of the imaging interval away from the standing area 210a.

The sole detection component 210 is the sole pressure plate. Sensors (not shown) are arranged corresponding to the foot shape below the standing area 210a for detecting the pressure points of the sole of the foot, and further judging whether there is inversion or eversion of the sole of the foot. In addition, the sensors can also detect other data such as body weight. Professionals can analyze based on the comprehensively obtained data and give correction suggestions according to the analysis results.

[0059] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
