[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0026] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0027] Example 1

[0028] In this embodiment, a three-dimensional human posture detector is proposed. Figure 1-5 The main body of the detector is composed of a support body 15, and a treading part composed of a first cover 2 and a second cover 9. It should be clarified here that the treading part covers the support body 15, and the treading part can rotate relative to the support body 15. Therefore, the coiled tube 1 surrounding the outer periphery of the support body 15 is set to a cylindrical or curved shape, and the human body posture can be scanned by using multiple scanning heads 6 arranged on the coiled tube 1 during one rotation of the treading part relative to the support body 15.

[0029] The three-dimensional human posture detector provided in this embodiment is not equipped with an active drive device in order to achieve the purpose of using a streamlined configuration. Of course, in order to achieve a balanced scanning effect when used by a single person, a power storage drive component is still configured. For details, please refer to Figure 2-5 An annular cavity for accommodating the elastic rod 5 is formed in the second cover 9 and the support body 15. In this way, the elastic rod 5 is combined with the insertion rod 3 and the second cover 9, and then when the second cover 9 rotates relative to the support body 15, the elastic force of the elastic rod 5 when it is stretched is used to accumulate the torque required for the second cover 9 to rotate in the opposite direction of the rotation of the second cover 9.

[0030] As mentioned above, the elastic rod 5 is a key component for accumulating torque. Of course, after accumulating torque, the accumulated torque needs to be locked. In this case, please continue to refer to Figure 2-5 A ring groove 10 is provided at the second cover 9 , and an elastic member is provided at the top of the ring groove 10 . In addition, there is a pin 7 , which is fixed in the support body 15 , extends into the ring groove 10 and contacts the elastic member during the rotation of the second cover 9 .

[0031] Regarding the elastic member, it extends from the top of the annular groove 10 into the annular groove 10 . It should be noted that the extension amount of the elastic member into the annular groove 10 is adjustable.

[0032] See also Figure 5The elastic member with adjustable extension includes a ball head rod 11 that enters the annular groove 10 along the height direction of the first cover 2 and a roller 4 that protrudes from the top of the first cover 2 and rotates, wherein the cavity where the roller 4 is located is connected to the cavity where the ball head rod 11 is located, and the roller 4 is connected to the ball head rod 11 through a soft rod 12, which is used to pull the ball head rod 11 to the cavity where the ball head rod 11 is located to move when the roller 4 is rotated.

[0033] Further explanation is given, there is a retaining ring 13 at the junction of the cavity where the roller 4 is located and the cavity where the ball head rod 11 is located. For this purpose, a spring 14 is set with the retaining ring 13 as the top, extending toward the ball head rod 11 and contacting the ball head rod 11, which is used to push the ball head rod 11 to quickly reset after rotating the roller 4.

[0034] Of course, in order to better match the ball head rod 11, a ball groove 8 adapted to the ball head rod 11 is opened at the end of the pin 7 facing the top of the annular groove 10. In this way, after the ball head rod 11 is inserted into the ball groove 8, the combination of the first cover 2 and the second cover 9 is made stationary relative to the support body 15.

[0035] From the above content, it can be seen that the key component for accumulating and releasing torque lies in the elastic member, that is, after the torque is fully accumulated, the ball head rod 11 is inserted into the ball groove 8 to prevent the second cover 9 from rotating in the opposite direction relative to the support body 15. On the contrary, when releasing the torque, the roller 4 is rolled by the person's feet, and the roller 4 is used to wrap around the soft rod 12 to pull the ball head rod 11. It can be foreseen that after the ball head rod 11 is pulled, there is no restraint between the second cover 9 and the pin 7. Therefore, the elastic force is released in combination with the elastic rod 5 to make the second cover 9 rotate in the opposite direction, and the process of reverse rotation is the process of rotation when the person is scanning.

[0036] See also Figure 2 and Figure 3 In this embodiment, the corners of the pins 7 on both sides of the ball groove 8 are cut into slopes, whereby the ball head rod 11 enters the ball groove 8 along the slopes.

[0037] In this embodiment, when the torque is released, the pedal part rotates one circle relative to the support body 15 (the person rotates one circle), that is, after the torque is released to exhaustion, the final torque is only used to lift the ball head rod 11 to re-enter the ball groove 8. In this way, it avoids the problem of local defects in imaging or overlapping imaging in some areas caused by insufficient or excessive rotation angles of the person.

[0038] When the elastic rod 5 releases the torque, the rotation speed of the pedal part gradually increases. However, considering the influence of the gradually increasing rotation speed on the scanning accuracy of the scanning head 6, a friction groove is provided on the top edge of the support body 15 ( Figure 2There is an identification mark in it, but no number is used), and an insertion rod 3 combined with the first cover 2 is set in the friction groove, wherein the bottom of the insertion rod 3 directly contacts the bottom of the friction groove. It should be noted that the friction coefficient of the bottom of the friction groove gradually increases starting from the pin 7.

[0039] In the above description of features, it is indicated that the friction coefficient of the bottom of the friction groove gradually increases starting from the pin 7. In this way, the increasing friction force is used to offset part of the torque, so that the pedal part to the support body 15 can rotate at a relatively uniform speed.

[0040] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0041] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
