[0034] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0035] Reference Figure 1-10 , an embodiment of an electric elastic band structure of the utility model is proposed:

[0036] A voice-controlled electric elastic band includes a housing and a strap 1. The tail of the strap 1 is fixedly connected to the housing, while the head of the strap 1 extends through the housing. The housing houses a motor assembly 2, a voice control board 3 for controlling the operation of the motor assembly 2, and a battery 31 connected to the voice control board 3. The voice control board 3 has an on / off button 32, and a pressure plate 33 is located on the back of the housing. The pressure plate 33 has a pressing portion 331 extending through the housing and is used to press the on / off button 32. The output end of the motor assembly 2 is in transmission connection with the back of the strap 1 via a transmission assembly 4. The strap 1 is driven by the motor assembly 2 to move linearly in the left-right direction.

[0037] The process for adjusting the tightness of the strap 1 of the present invention is as follows: First, the user applies body pressure to the pressure plate 33 and presses the switch button 32, activating the voice control panel 3. The user then uses voice control to operate the motor assembly 2, which drives the strap 1 in a linear motion in the left and right directions, thereby adjusting the tightness of the strap 1. This utility model can be applied to products such as waist belts and seat belts. When the elastic band is used as a waist belt, the user applies pressure to the pressure plate 33 through the rise and fall of the abdomen. When the elastic band is used as a seat belt, the user applies pressure to the pressure plate 33 through the rise and fall of the chest. The user does not need to use both hands to operate the strap 1, making it suitable for people with disabilities who have difficulty using their hands or have lost their hands.

[0038] When the voice control panel does not receive any instructions within the specified time (usually set to 10~20s), the voice control panel automatically stops working to avoid consuming power and extending the use time of the electric elastic band when the strap tension does not need to be adjusted.

[0039] like Figure 1 As shown, the pressing plate 33 is provided with a first connecting ear 332 and a pressing portion 331 on the side facing the shell, and a hinge shaft 51 extending in the vertical direction is provided in the shell. The first connecting ear 332 passes through the shell and is connected to the hinge shaft 51, so that the pressing plate 33 is installed on the shell.

[0040] like Figure 4 As shown, the housing includes an outer shell 5 and a panel 6 located at the front end of the outer shell 5. The motor assembly 2, voice control board 3, and battery 31 are installed in the outer shell 5. The panel 6 has a pressing portion 61 on the side facing the outer shell 5. The panel 6 is separated from the front end of the outer shell 5 by the pressing portion 61 to form a channel for the strap 1 to pass through.

[0041] like Figure 5 As shown, each of the four corners of panel 6 is provided with a pressing portion 61, two of which are equipped with a second connecting lug 63. The second connecting lug 63 extends into the housing 5 and connects to the hinge shaft 51, allowing the panel 6 to rotate relative to the housing 5. The hinge shaft 51 is protected by a second torsion spring 52. To release the strap 1, the panel 6 is rotated about the hinge shaft 51 and then separated from the housing 5. The second torsion spring 52 is compressed. When the panel 6 is released, the second torsion spring 52 returns the panel 6 to its original position.

[0042] The housing 5 is provided with a lock buckle 7 , and the other two pressing portions 61 of the panel 6 are both provided with third connecting ears 64 . The third connecting ears 64 are provided with locking holes 641 for detachable connection with the lock buckle 7 .

[0043] The lock buckle 7 includes a knob 71 located outside the housing 5 and a rotating shaft 72 located inside the housing 5. A rotating hole is provided in the housing 5, and one end of the rotating shaft 72 is connected to the rotating hole. The other end of the rotating shaft 72 passes through the housing 5 and is connected to the knob 71. The rotating shaft 72 is provided with a buckle 73 for engaging with the locking hole 641 and a first torsion spring 74 located between the buckle 73 and the rotating hole. When the strap 1 is in use, the third connecting ear 64 passes into the housing 5, and the locking hole 641 is connected to the buckle 73, so that the panel 6 is fixed relative to the housing 5 to prevent the strap 1 from being separated from the housing 5. When the strap 1 needs to be untied, the knob 71 is rotated to disengage the buckle 73 from the locking hole 641, and then the third connecting ear 64 is moved out of the housing 5. The first torsion spring 74 is compressed, and then the knob 71 is released, and the first torsion spring 74 resets the lock buckle 7.

[0044] like Figure 1 As shown, the voice control board 3 includes a circuit board 34, a microphone 35 connected to the circuit board 34, and a housing 5 is provided with a sound receiving hole 53 opposite to the microphone 35. The microphone 35 is used to receive voice commands.

[0045] A magnetic charging port 55 is provided on the outer surface of the housing 5 .

[0046] A rack 11 is provided on the back of the strap 1, and the transmission assembly 4 includes a gear 41 and a clutch assembly for transmitting and connecting the output end of the motor assembly 2 and the gear 41; a gear through-hole 54 is provided on the front face of the housing 5, and the gear 41 engages with the rack 11 after passing through the gear through-hole 54; when an external force pulls the strap 1, the clutch assembly is used to reduce the damage of the external force to the motor assembly 2.

[0047] like Figure 6-10 As shown, the clutch assembly includes a fixed ring 42, a moving ring 43 located inside the fixed ring 42, and a clutch output shaft 44; the clutch output shaft 44 passes through the axis of the gear 41 and is in transmission connection with the gear 41; the moving ring 43 includes a connecting shaft portion 431 for transmission connection with the output end of the motor assembly 2, and the connecting shaft portion 431 is provided with at least two transmission portions 432 around the axis of the connecting shaft portion 431, and the interval between adjacent transmission portions 432 is a movable recess 433, and a locking member 45 is provided in the movable recess 433; one end of the clutch output shaft 44 is a transmission end 442, and the transmission end 442 is placed in a rotating shaft groove 434 formed around the transmission portion 432, and the locking member 45 is passed through the movable recess 433 and the rotating shaft groove 434, and the outer periphery of the transmission end 442 is provided with a transmission recess 441 for contact with the locking member 45.

[0048] The distance between the center of the transmission recess 441 and the inner surface of the fixing ring 42 is greater than the width of the locking member 45; and the distance between the transmission recess 441 and the inner surface of the fixing ring 42 gradually decreases from the center to the left and right sides of the transmission recess 441, and the distance between the left and right sides of the transmission recess 441 and the inner surface of the fixing ring 42 is less than the width of the locking member 45. Figure 9 As shown, when the locking member 45 is aligned with the center of the transmission recess 441, the transmission end 442 and the locking member 45 are in a separated state; Figure 10 As shown, when the locking member 45 contacts the left and right sides of the transmission recess 441 , the transmission end 442 and the locking member 45 are in an engaged state.

[0049] When an external force is applied to pull the strap 1, the clutch assembly reduces the power transmitted to the output end of the motor assembly 2 by the gear 41. The process is as follows: When an external force is applied to pull the strap 1, the rack 11 drives the gear 41 and the clutch output shaft 44 to rotate together. The transmission end 442 first rotates to the transmission recess 441 and contacts the locking member 45, causing the power transmitted to the output end of the motor assembly 2 by the gear 41 to be reduced. At this time, the output end of the motor assembly 2 is still not affected by the gear 41, and acts as a buffer. Then, the transmission recess 441 pushes the locking member 45 toward the transmission part 432, further reducing the power transmitted to the output end of the motor assembly 2 by the gear 41. At this time, the output end of the motor assembly 2 is still not affected by the gear 41. If the external force that pulls the strap 1 is small or the external force acts for a short time, the transmission recess 441 will not continue to drive the transmission part 432 to rotate through the locking member 45. If the external force acting on the strap 1 is large or the external force acts for a long time, the transmission recess 441 will continue to drive the transmission part 432 to rotate through the locking member 45. At this time, the motion ring 43 will drive the output end of the motor assembly 2, but the power transmitted to the output end of the motor assembly by the gear 41 has been gradually reduced, thereby reducing the damage to the motor assembly 2 caused by the external force during the process of manually pulling the strap 1.

[0050] The motor assembly 2 includes a motor 21 and a reduction gear box 22 . The output end of the motor 21 is transmission-connected to the coupling portion 431 via the reduction gear box 22 .

[0051] The housing further includes a tail clip 8 for clamping the tail of the belt. The tail clip 8 is hinged to the left or right side of the housing 5 and can rotate relative to the housing 5 .

[0052] The preferred embodiment does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
