[0030] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application, and the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those skilled in the art without creative work on the basis of the embodiments of the present application shall belong to the protection scope of the present application.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, a height adjustment mechanism for a wearable device is located between a back unit 2 and a waist unit 3, and includes an upper back plate 11 for mounting the back unit 2, a telescopic frame is provided on the side of the upper back plate 11 facing away from the human body, and a recessed portion 211 for accommodating the telescopic frame is provided on the shell 21 of the back unit 2.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, the telescopic frame includes two guide blocks 12 of identical structure and symmetrical arrangement, and the upper end of the guide block 12 is fixedly connected to the upper back plate 11 by screws. The inner side surface of the guide block 12 (the inner side is the side opposite to the two guide blocks 12) is provided with a guide groove penetrating the guide block 12 in the vertical direction. A connecting rod 13 is provided between the two guide blocks 12, and the two ends of the connecting rod 13 are respectively inserted into the guide groove. Under the guiding action of the guide groove, the connecting rod 13 can slide up and down relative to the guide block 12. The lower end of the connecting rod 13 is fixedly connected to the waist unit 3 in a detachable manner. Both guide blocks 12 are provided with a locking mechanism 14 for fixing the connecting rod 13.

[0033] As a specific implementation, the waist unit 3 described in this embodiment is provided with an insertion port, the lower end of the connecting rod 13 is inserted into the insertion port, and is fixedly connected to the waist unit 3 by a tightening bolt.

[0034] like Figure 5 , Figure 6 and Figure 7 As shown, the locking mechanism 14 includes a mounting block 141, and the mounting block 141 is fixedly connected to the guide block 12 by screws. The mounting block 141 is provided with a guide hole that penetrates the mounting block 141 along a sliding direction perpendicular to the connecting rod 13, and a limiting column that can slide axially along the guide hole is provided in the guide hole, and a spring 143 is provided between the mounting block 141 and the limiting column to prevent the guide column from moving away from the guide block 12. The outer end of the limiting column (the end facing away from the guide block 12 is the outer end) extends to the outside of the mounting block 141, and is rotatably connected to the adjustment block 145 through the hinge shaft 144. The adjustment block 145 includes a first positioning surface and a second positioning surface, and the distance M from the first positioning surface to the hinge shaft 144 is greater than the distance N from the second positioning surface to the hinge shaft 144. The guide block 12 is provided with an avoidance hole allowing the limit column to pass through, and the connecting rod 13 is provided with a plurality of limit holes 131 matched with the limit column in the vertical direction.

[0035] like Figure 6As shown, when the first positioning surface is pressed against the mounting block 141 under the elastic force of the spring 143, the inner end of the limit column (the end facing the connecting rod 13 is the inner end) is separated from the connecting rod 13. At this time, the locking mechanism 14 is in an open state, and the connecting rod 13 can slide up and down relative to the guide block 12, so as to adjust the height. When the height is adjusted to a suitable height, a limit hole 131 on the connecting rod 13 is aligned with the avoidance hole on the guide block 12, and then the adjustment block 145 is rotated so that the second positioning surface of the adjustment block 145 faces the guide block 12, and then the hand is released, as shown in FIG. Figure 7 As shown, at this time, the second positioning surface of the adjustment block 145 will be pressed against the mounting block 141 under the elastic force of the spring 143, and the inner end of the limiting column (with the end facing the connecting rod 13 as the inner end) will pass through the avoidance hole on the guide block 12 and be inserted into the limiting hole 131 of the connecting rod 13. The locking mechanism 14 is in a locked state, and the connecting rod 13 cannot slide up and down relative to the guide block 12.

[0036] No matter the locking mechanism 14 is in the open or locked state, the spring 143 is in the compressed state, so that the position of the adjustment block 145 can be maintained and will not be randomly changed due to vibration, accidental touch, etc.

[0037] As a specific implementation, in this embodiment, a plug-in boss is provided on one side of the mounting block 141 facing the guide block 12 , and the plug-in boss is inserted into the avoidance hole and is positioned and matched with the avoidance hole.

[0038] Furthermore, in order to improve the structural strength, e.g. Figure 4 and Figure 5 As shown, a connecting plate 15 is provided between the two guide blocks 12 below the upper back plate 11, and both ends of the connecting plate 15 are fixedly connected to the guide blocks 12 by screws. Preferably, both ends of the connecting plate 15 are fixedly connected to the lower end of the guide block 12 by screws, and two connecting plates 15 are provided between the two guide blocks 12, and the two connecting plates 15 are respectively located on both sides of the connecting rod 13.

[0039] Furthermore, if Figure 4As shown, a lower limit stopper 132 is provided on the connecting rod 13 above the connecting plate 15, and the lower limit stopper 132 determines the lower limit position of the connecting rod 13 moving downward relative to the guide block 12. By providing the lower limit stopper 132 and cooperating with the connecting plate 15, it is possible to prevent the connecting rod 13 from slipping out of the guide groove when the height is adjusted. An upper limit stopper 121 is provided at the upper end portion of the guide block 12, and one end of the upper limit stopper 121 extends into the guide groove. The upper limit stopper 121 determines the limit position of the connecting rod 13 moving upward relative to the guide block 12. Exemplarily, the upper limit stopper 121 and the lower limit stopper 132 are both screws.

[0040] Furthermore, if Figure 5 A cover plate 16 is provided between the two guide blocks 12 on the side facing the human body, and both ends of the cover plate 16 are fixedly connected to the guide blocks 12 by screws. An observation port 161 is provided on the cover plate 16, and a gear mark for indicating the height gear is provided on the connecting rod 13. When adjusting the height, the operator can judge the gear height by viewing the gear mark displayed in the observation port 161, so that the operator can select a suitable gear height according to his own size.

[0041] As a specific implementation method, Figure 6 and Figure 7 As shown, the limiting column described in this embodiment includes a first shaft section 1421 and a second shaft section 1422 in a direction away from the connecting rod 13, the diameter of the first shaft section 1421 is greater than the diameter of the second shaft section 1422, and a first step surface is formed between the first shaft section 1421 and the second shaft section 1422. The guide hole for accommodating the limiting column includes a first hole section and a second hole section in a direction away from the connecting rod 13, the diameter of the first hole section is greater than the diameter of the second hole section, and a second step surface is formed between the first hole section and the second hole section. The spring 143 is located in the first hole section and is sleeved on the second shaft section 1422 of the limiting column, one end of the spring 143 abuts on the first step surface, and the other end of the spring 143 abuts on the second step surface.

[0042] Preferably, the diameter of the first shaft segment 1421 matches that of the first hole segment, and forms a sliding fit; the diameter of the second shaft segment 1422 matches that of the second hole segment, and forms a sliding fit.

[0043] Furthermore, if Figure 4 and Figure 5As shown, connecting baffles 1411 are respectively provided on both sides of the adjusting block 145 on the mounting block 141, and at least one of the connecting baffles 1411 is fixedly connected to the mounting block 141 in a detachable manner. The hinge shaft 144 is located between the two connecting baffles 1411, and under the limiting effect of the two connecting baffles 1411, the hinge shaft 144 cannot escape from the hinge hole. Even if the spring 143 is in an extreme compression state, the hinge shaft 144 is still restricted between the two connecting baffles 1411 and cannot escape from the hinge hole. The adjusting block 145 is clamped between the two connecting baffles 1411, and the two connecting baffles 1411 limit the freedom of the adjusting block 145 to rotate around the axis of the limiting column.

[0044] As a specific implementation, in this embodiment, one of the connecting baffles 1411 and the mounting block 141 is an integrated structure, and the other connecting baffle 1411 is fixedly connected to the mounting block 141 by screws. This can not only limit the hinge shaft 144 to prevent the hinge shaft 144 from falling out of the hinge hole, but also facilitate installation and removal.

[0045] Furthermore, the connecting rod 13 is a hollow tube, and the inside is hollow for routing wires, which not only enables the wires to be built-in without being exposed, ensuring beauty, but also reduces the risk of wire damage. The connecting rod 13 is made of a light-weight, high-strength carbon fiber material, ensuring structural stability while reducing weight.

[0046] like Figure 8 As shown, by arranging the height gear adjustment mechanism on the back unit 2 and the waist unit 3, when the height gear adjustment mechanism is adjusted, the height distance between the waist unit 3 and the back unit 2 can be changed to meet the wearing needs of people of different heights, ensure that the back unit 2 always fits against the back of the human body, and the waist unit 3 always fits against the waist of the human body, thereby ensuring wearing comfort.
