Description

Technical Field

[0001] The utility model relates to a locking device for a resistance motor which can prevent a traction part of a sports equipment from being pulled out arbitrarily and unable to be retracted when the equipment is stopped and stationary. Background Art

[0002] Common sports equipment currently uses a motor shaft to generate resistance when rotating and retracting, and uses the resistance as a weight load source for gravity training to exercise muscles in various parts of the body. For example, in common rope pulling training, when the power of the motor is turned off, the shaft stops rotating and retracting. Once the rope is pulled by hand, the rope will lose the power to retract and return to its original position, which will cause obstacles and troubles in use.

[0003] The new patent case No. M632778 "Drawstring resistance mechanism for fitness equipment" announced by Taiwan, China on October 1, 2022, discloses: it includes a drive unit, a drawstring and a brake unit. The drive unit has a motor and a reel connected to the motor. The drawstring is connected to the reel at one end so that the drawstring can be pulled by the reel and wound around the reel. The brake unit has a brake member adjacent to the reel. When the brake member is in the brake position, it abuts against the reel, so that the reel cannot rotate when the motor is turned off. When the brake member is in the release position, it leaves the reel, so that the reel can be driven by the motor to rotate. In this way, the drawstring resistance mechanism can prevent the drawstring from being easily pulled out after the motor is turned off.

[0004] The prior patent mainly uses friction to prevent the drawstring from being pulled out, and when the force pulling the drawstring is greater than the friction, the drawstring will also be pulled out. Especially after long-term use, the brake end of the brake unit will be worn, so the friction is weakened and it is not possible to effectively fix the drawstring to prevent it from being pulled out, so it is not ideal in use. Utility Model Content

[0005] In order to solve the defect that the resistance motor of the conventional sports equipment cannot effectively retract and fix the pull rope, the purpose of the utility model is to provide an electric locking structure of the resistance motor of the sports equipment.

[0006] The utility model provides an electric locking structure of a resistance motor of sports equipment, comprising: a frame; a resistance motor, fixed to the frame, the resistance motor having an output shaft for outputting a resistance; a rotating disk, fixed to the output shaft; a locking disk, fixed to the output shaft, the locking disk being provided with a plurality of locking spaces; a traction member, wound around the rotating disk, for pulling the rotating disk to overcome the resistance; a locking bolt, movably arranged on the frame; an electric control element, connected to the locking bolt; a power storage unit, electrically connected to the electric control element; when the resistance motor is stationary, the electric control element selectively drives the locking bolt to make the locking bolt disengage from or extend into any of the locking spaces to release or restrict the output shaft, thereby unlocking or locking the resistance motor.

[0007] The electric control element is a control motor or a solenoid valve.

[0008] A control disk is fixed to an axis of the control motor, and the control disk is connected to the lock bolt through a cable to drive the lock bolt to be separated from or extended into the locking space.

[0009] The above-mentioned locking bolt is arranged in a fixing seat, which is fixed to the frame. A stop portion is arranged on the peripheral ring of the locking bolt. A return spring is sleeved on a rear edge section of the locking bolt located on the stop portion. The return spring elastically presses between the stop portion and the inner wall of the fixing seat.

[0010] The cable comprises a first cable and two second cables, one end of the first cable is connected to the control panel, one end of the two second cables is respectively connected to the rear edge sections of the two locking bolts, and the other end of the first cable and the other end of the two second cables are respectively connected to a linkage block.

[0011] The locking bolt is arranged parallel to the output shaft.

[0012] The locking plate is independently combined with the rotating plate, or is integrally formed with the rotating plate.

[0013] The locking space is a hollow slot hole arranged in the axial direction of the locking disk, or a groove arranged on the circumference of the locking disk.

[0014] The locking space is centered on the output shaft and is arranged in a ring on the locking plate.

[0015] The traction member is a cable, a webbing or a pull rope.

[0016] The above technical features have the following advantages:

[0017] 1. The lock bolt is mainly made use of the elastic restoring force released by the reset spring to move the lock bolt out and get stuck in any locking space on the locking plate. The locking plate is clamped by the lock bolt to limit the rotation of the output shaft, so as to form a locked state for the resistance motor, thereby preventing the traction member from being pulled out arbitrarily.

[0018] 2. When the resistance motor of the sports equipment is stopped and stationary, the winding traction member will not be pulled out at will, resulting in the disadvantage of being unable to be retracted. At the same time, it will not cause obstruction and trouble due to being pulled out.

[0019] 3. By using a single set of electric control components and the linkage action of the linkage block, one set of first cable members can be linked to drive more than two sets of second cable members, thereby effectively simplifying the number of linkage components and making the overall structure simple.

[0020] 4. The power required to drive the electronic control components is supplied by a small current storage unit, so it is extremely energy-saving when used. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In the following embodiments of the present invention, if left, right, front, back, up, down, etc. are mentioned, they are based on the operator A (see Figure 7 ) Sitting on the sitting and lying part 11 of the frame 1 of the present invention, the operator A stands upright with his upper body and his eyes looking straight ahead. The relative position recognized by this directional term is only for the convenience of describing the embodiments of the present invention and does not limit the spatial form of the present invention.

[0031] See also Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the utility model includes: a frame 1, a resistance motor 2, a rotating disk 3, a locking disk 4, a traction member 5, a locking bolt 6, an electric control element 7 and a storage unit 8, wherein:

[0032] A frame 1 extends along a horizontal direction X, and the frame 1 is provided with a sitting or lying portion 11. The sitting or lying portion 11 extends along the horizontal direction X, and the sitting or lying portion 11 comprises a first cushion 111 and a second cushion 112, and the first cushion 111 and the second cushion 112 are multi-stage adjustable for lifting and positioning.

[0033] A resistance motor 2 is fixed to the frame 1. The resistance motor 2 has an output shaft 21 for outputting a resistance. The embodiment of the utility model is provided with two sets of the resistance motors 2, and the two resistance motors 2 are arranged at one end of the frame 1 in opposite directions.

[0034] A rotating disk 3, such as Figure 4 As shown, it is fixed to the output shaft 21 of the resistance motor 2.

[0035] A locking plate 4 is fixed to the output shaft 21 of the resistance motor 2. The locking plate 4 can be independently combined with the side of the rotating plate 3, or integrally formed with the side of the rotating plate 3. Figure 4 As shown, the side of the locking plate 4 is provided with a plurality of locking spaces 41, and the plurality of locking spaces 41 are provided in the hollow slots in the axial direction of the locking plate 4, or in the grooves on the circumference of the locking plate 4. Moreover, the plurality of locking spaces 41 are arranged in a ring on the locking plate 4 with the output shaft 21 as the center.

[0036] A traction member 5 is provided, one end of which is wound around the rotating disk 3 and the other end of which is connected to a handle 51. The traction member 5 is a pull rope, a webbing or a pull cord, which can be held by hand on the handle 51. The rotating disk 3 is pulled by the traction member 5, and force can be applied to the traction member 5 to overcome the aforementioned resistance, thereby achieving the effect of gravity training.

[0037] A lock bolt 6, such as Figure 5 As shown, it is arranged in a fixing seat 61, a stopper 62 is arranged on the periphery of the lock bolt 6, a return spring 64 is sleeved on a rear edge section 63 of the lock bolt 6 located on the stopper 62, and the return spring 64 elastically presses between the stopper 62 and the inner wall of the fixing seat 61. The fixing seat 61 is fixed to the frame 1, so that the lock bolt 6 is arranged parallel to the output shaft 21.

[0038] An electric control element 7 is connected to the lock bolt 6. The electric control element 7 is a control motor or a solenoid valve. The present utility model embodiment uses the control motor as an example. Figure 6 As shown, a control disk 72 is fixed to an axis 71 of the electric control element 7, and the control disk 72 is connected to the lock bolt 6 through a cable 73. The cable 73 includes a first cable 731 and two second cables 732. One end of the first cable 731 is connected to the control disk 72, one end of the second cable 732 is connected to the rear edge section 63 of the lock bolt 6, and the other end of the first cable 731 and the other end of the second cable 732 are respectively connected to a linkage block 74. Since the embodiment of the utility model is provided with two groups of the resistance motor 2, two groups of the rotating disk 3, the locking disk 4, the traction member 5 and the lock bolt 6 are also provided, which can be pulled by the left and right hands together or separately as gravity training. The two lock bolts 6 can be connected to the two second cables 732 respectively. The first cable 731 and the two second cables 732 are respectively a steel cable. When the resistance motor 2 is stationary, the electric control element 7 can selectively drive the lock bolt 6 to disengage from or extend into any of the locking spaces 41 , thereby releasing or restricting the output shaft 21 , thereby unlocking or locking the resistance motor 2 .

[0039] A power storage unit 8 is fixed to the frame 1. The power storage unit 8 is electrically connected to the electric control element 7 to supply the electric power required when the electric control element 7 is powered on and started.

[0040] When using, Figure 1 , Figure 2 and Figure 3As shown, first, the electric control element 7 and the resistance motor 2 are started. The electric control element 7 is started by powering on. The power storage unit 8 can supply power to the electric control element 7, so that the axis 71 of the electric control element 7 starts to rotate to generate a pulling force, thereby driving the control plate 72 to retract the first cable 731. Then, the first cable 731 links the two second cables 732 through the linking block 74, as shown in FIG. Figure 4 and Figure 5 As shown, the two second ropes 732 can be used to pull the lock bolt 6 respectively, so that the stopper 62 of the lock bolt 6 elastically compresses the return spring 64, thereby accumulating an elastic restoring force, so that the lock bolt 6 is retracted into the fixed seat 61. In this way, the lock bolt 6 is withdrawn from any of the locking spaces 41 of the locking plate 4, thereby releasing the output shaft 21, so as to form an unlocked state for the resistance motor 2. At the same time, after the resistance motor 2 is started, the output shaft 21 of the resistance motor 2 can output a resistance, and the resistance is fed back to the handle 51 through the traction member 5. Figure 7 As shown, at this time, a user A can sit on the sitting and lying part 11, and then hold the handle 51 with one or both hands, and then pull the traction member 5 to overcome the resistance, so as to perform gravity training on the hands.

[0041] When no training is required, such as Figure 1 , Figure 2 and Figure 3 As shown, the electric control element 7 and the resistance motor 2 can be turned off to interrupt the power storage unit 8 from supplying power to the electric control element 7. By stopping the electric control element 7 after power failure, the axis 71 of the electric control element 7 stops rotating to output the pulling force. After the pulling force disappears, the control plate 72 is no longer driven, and the first cable 731 is relaxed. At the same time, the two second cables 732 are linked and relaxed through the linkage block 74. Since the second cable 732 is no longer affected by the pulling force, it will no longer pull the lock bolt 6. The lock bolt 6 can release the elastic restoring force through the reset spring 64, as shown in FIG. Figure 8 As shown, the locking bolt 6 can be moved out of the fixing seat 61 and inserted into any of the locking spaces 41 on the locking plate 4. The locking plate 4 is clamped by the locking bolt 6 to limit the rotation of the output shaft 21, so as to form a locked state for the resistance motor 2. In this way, the output shaft 21 of the resistance motor 2 cannot rotate, and even if the resistance motor 2 does not output the resistance, the user A cannot pull the traction member 5 by holding the handle 51. Therefore, when the resistance motor 2 is stopped and stationary, the traction member 5 will not be pulled out at will, and the disadvantage of being unable to be retracted will not occur, and at the same time, it will not cause obstacles and troubles due to being pulled out.

[0042] like Figure 6As shown, the utility model uses a single set of the electric control element 7 at the same time, and through the linkage of the linkage block 74, the first cable member 731 of one set can be linked to more than two sets of the second cable members 732. Therefore, the number of linkage components can be effectively simplified, so that the overall structure can be simple. And the power storage unit 8 with a small current supplies the power required for the operation of the electric control element 7, so it is extremely energy-saving when used, and it is also quite easy to operate.

[0043] Based on the description of the above embodiments, one should be able to fully understand the operation, use and effects of the present invention. The above embodiments are only preferred embodiments of the present invention and should not be used to limit the scope of implementation of the present invention. That is, simple equivalent changes and modifications made according to the contents of the present invention specification are all within the scope of the present invention.
