[0002] Existing backpacks provide convenience for people to carry items when traveling, but they still have the following defects: due to the weight of the items in the backpack, the backpacker's shoulders, back and waist are under pressure. Over time, the backpacker will feel uncomfortable, easily fatigued and painful, which is harmful to the user's health. With the advancement of technology, backpacks with massage functions have been designed based on traditional backpacks. For example, the utility model patent with authorization announcement number CN216908545U provides a massage backpack back system. However, since there is only one massage head on the shoulder strap and the massage head is relatively large in size, when the backpack is actually carried, when massage is not needed, the massage head will cause the user's shoulders to rub, which increases the discomfort. Therefore, further improvement is needed. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention is further described below through specific implementation methods.

[0025] Example 1

[0026] like Figures 1 to 3 As shown, the utility model describes an expandable massage strap, comprising a strap body 1 and a massage vibrator 2, wherein the strap body 1 is provided with a accommodating cavity 11, a placement bag 3 is fixedly provided in the accommodating cavity 11, and the massage vibrator 2 is arranged in the placement bag 3, and the strap body 1 is provided with an expansion device 4, which is used to expand the volume of the accommodating cavity 11. When massage is required, the volume of the accommodating cavity 11 is not expanded so that the strap body 1 applies force to the massage vibrator 2. When massage is not required, the volume of the accommodating cavity 11 can be expanded so that the strap body 1 does not apply force to the massage vibrator 2.

[0027] By setting the expansion device 4, the volume of the accommodating chamber 11 can be expanded accordingly, thereby changing the force applied by the shoulder strap body 1 to the massage vibrator 2 during use. When massage is required, the volume of the accommodating chamber 11 is not expanded by the expansion device 4. At this time, the massage vibrator 2 is compressed by the shoulder strap body 1 and is in a force-bearing position between the shoulder strap body 1 and the user's shoulder, so that the shoulder strap body 1 applies force to the massage vibrator 2, and then by controlling the massage vibrator 2 to vibrate, the massage function can be achieved. When massage is not required, the volume of the accommodating chamber 11 can be expanded by the expansion device 4. At this time, the massage vibrator 2 is no longer compressed by the shoulder strap body 1 and is no longer in a force-bearing position between the shoulder strap body 1 and the user's shoulder, so that the shoulder strap body 1 no longer applies force to the massage vibrator 2. Therefore, the problem of the massage vibrator 2 causing the user's shoulder to rub can be effectively alleviated, thereby greatly reducing discomfort.

[0028] Correspondingly, a placement cavity open upward is provided in the placement bag 3, and the placement cavity is adapted to the massage vibrator 2. The massage vibrator 2 is detachably arranged in the placement cavity, and the massage vibrator 2 is flat. Preferably, the placement bag 3 is elastic and tightly clamped on the outer periphery of the massage vibrator 2 to ensure that the massage vibrator 2 is stable and convenient in the placement bag 3. In addition, by adopting the flat massage vibrator 2, it is also beneficial to reduce the discomfort caused by the shoulder.

[0029] Correspondingly, the expansion device 4 includes a first connecting member 41, and an expansion port 12 arranged along the length direction of the strap body 1 is provided in the middle of the front side of the strap body 1, the expansion port 12 is communicated with the accommodating cavity 11 and corresponds to the massage vibrator 2, and the upper and lower ends of the expansion port 12 extend to the upper and lower ends of the accommodating cavity 11 respectively. The first connecting member 41 is provided at the expansion port 12 of the strap body 1 and is used to close or open the expansion port 12. Preferably, the first connecting member 41 is a first zipper. As a result, when the first zipper is closed, the expansion port 12 is in a closed state to increase the massage effect. When the user does not need massage or wants to relieve the problem of massage on the shoulders, the user can open the first zipper to make the expansion port 12 open. The expansion port 12 is in the expanded state, thereby expanding the accommodating cavity 11 to a certain extent and releasing the force applied by the shoulder strap body 1 to the massage vibrator 2. At this time, the massage vibrator 2 can effectively alleviate the problem of the user's shoulders being rubbed by the user, thereby greatly reducing the discomfort. In addition, by controlling the opening and closing degree of the first zipper, the massage intensity can also be adjusted to a certain extent. The adjustment of the massage intensity is simple and quick, and the user can easily adjust the massage intensity to reduce the discomfort. In addition, through the setting of the expansion port 12 and the first zipper, the massage vibrator 2 can also be quickly disassembled and assembled, which is convenient for the user to maintain. In other embodiments, the first connecting member 41 can also be a first Velcro, a first button or a first snap.

[0030] The expandable massage strap also includes a control main board, a function control board and a power supply device. The massage vibrator 2, the function control board and the power supply device are electrically connected to the control main board through cables. The cables between the control main board and the massage vibrator 2 and the cables between the control main board and the function control board are provided with quick-release connectors that can disconnect the cables to facilitate the control of the massage vibrator 2 to operate.

[0031] Example 2

Preferably, the second connecting piece 43 is a second zipper, so that when the second zipper is closed, the accommodating cavity 11 is in a non-expanded state, and the sealing piece 44 can exert a certain degree of pressure on the massage vibrator 2. The second zipper 44 can be used to expand the accommodating cavity 11 to a certain extent, and release the force exerted by the shoulder strap body 1 and the sealing piece 44 on the massage vibrator 2. At this time, the sealing piece 44 will not exert corresponding force on the massage vibrator 2, which can effectively alleviate the problem of the massage vibrator 2 causing the user to rub the shoulder, thereby greatly reducing the discomfort. In this example, the accommodating cavity 11 is always in a closed state and the massage vibrator 2 is not exposed to the outside. In addition, by controlling the opening and closing degree of the second zipper, the massage intensity can be adjusted to a certain extent. The adjustment of the massage intensity is simple and quick, and the user can easily adjust the massage intensity to reduce discomfort. In other embodiments, the second connecting member 43 can also be a second Velcro, a second button or a second snap.

[0033] In addition, the sealing piece 44 is also provided with a take-in and put-out port, and the sealing piece 44 is fixedly provided with a third connecting member 45 at the take-in and put-out port. The third connecting member 45 is used to close or open the take-in and put-out port. Preferably, the third connecting member 45 is a third zipper. Through the setting of the take-in and put-out port and the third zipper, the massage vibrator 2 can also be quickly disassembled and assembled, which is convenient for users to perform maintenance.
