Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a fitness pump. Background Art

[0002] Fitness pumps are currently popular among athletes as a popular fitness exercise device. Existing fitness pumps are often composed of a motor, a reduction gearbox, and a winding reel. During use, the reduction gearbox rotates at high speed, generating significant vibration and noise that can affect the user's exercise experience. Therefore, it is necessary to isolate the vibration and noise generated by the reduction gearbox to improve the user experience.

[0003] Furthermore, during the use of the fitness pump, due to the loss at the reduction gearbox, the force output by its motor is often not equal to the tension obtained by the user through the pull wire, which affects the control of the motor and the function of the fitness pump. Therefore, it is necessary to measure the tension on the pull wire at the outlet of the pull wire, but the existing technology does not disclose how to measure the tension here, and only the reciprocating pull wire is moving here, and there is a lack of a measuring object that can accurately reflect the tension on the pull wire at the outlet.

[0004] Furthermore, during use, fitness pumps need to be secured at various locations around the user to help them achieve different exercise goals or postures. Therefore, a quick-disassembly device is needed to quickly install and remove the fitness pump. Furthermore, the quick-disassembly device must secure the fitness pump securely and reliably, posing a safety hazard to the user if the pump falls off during exercise. Therefore, fitness pumps require a quick-disassembly device that meets both fast assembly and disassembly requirements and meets safety requirements.

[0005] The information disclosed in this background art is only for understanding the background of the concept of the present invention and therefore it may include information that does not constitute prior art. Utility Model Content

[0006] In response to the above problem or one of the above problems, an object of the present invention is to provide a fitness pump, which is provided with an elastic member inside to isolate the vibration and noise generated by the reduction box, thereby improving the user experience of the fitness pump.

[0007] In response to the above problem or one of the above problems, the second purpose of the present invention is to provide a fitness pump, in which an elastic part is arranged between the motor unit and the outer shell. On the one hand, it effectively isolates the vibration and noise generated by the motor unit as a whole, thereby improving the user experience of the fitness pump; on the other hand, since the elastic part is used to fix the motor unit, the motor unit can produce a slight displacement relative to the outer shell when subjected to external force, forming a measuring object that can accurately reflect the magnitude of the tension exerted on the pull wire at the outlet, creating conditions for accurately measuring the magnitude of the tension exerted on the pull wire at the pull wire outlet, and the structure is simple and practical.

[0008] In response to the above problem or one of the above problems, the third purpose of the present invention is to provide a fitness pump. By setting a quick-release fixing unit, on the one hand, the fitness pump is not easy to fall off, which can meet the stable and reliable safety requirements; on the other hand, the fitness pump can be quickly installed and disassembled, with a simple structure, practicality, and is indeed feasible.

[0009] In order to achieve one of the above purposes, the first technical solution of the present utility model is:

[0010] A fitness pump comprises an outer shell with an inner cavity and a motor unit arranged inside the outer shell; the motor unit is assembled inside the outer shell via an elastic member so that the motor unit can be displaced relative to the outer shell when subjected to an external force and return to its original position after the external force disappears.

[0011] As a preferred technical measure, the outer shell is provided with a cable outlet, and a force sensor is installed at the cable outlet. When the motor unit is subjected to cable tension, the force sensor measures the tension. The force sensor at the cable outlet accurately measures the tension applied to the cable at the outlet, thereby optimizing motor control and better achieving the fitness pump function.

[0012] As a preferred technical measure, the force sensor is a strain gauge pressure sensor including a strain gauge. The strain gauge is mounted at the cable outlet via a strain gauge seat. When the motor unit is subjected to cable tension, the motor unit displaces relative to the outer housing toward the cable outlet, thereby causing the strain gauge to deform. The strain gauge deformation is used to measure the cable tension. With a strain gauge pressure sensor, when subjected to cable tension, the motor unit displaces relative to the outer housing, compressing the strain gauge. The cable tension is then calculated using circuitry.

[0013] As a preferred technical measure: the elastic member is a rubber block, and the motor unit is fixed to the interior of the outer shell by a plurality of rubber blocks distributed around the motor unit. The elastic member is a rubber block distributed around the motor unit, so that the motor unit can be displaced within the outer shell when subjected to external force.

[0014] In order to achieve one of the above purposes, the second technical solution of the utility model is:

[0015] A fitness pump comprises an outer shell with an inner cavity, and a quick-release fixing unit is provided on the outside of the outer shell, and the quick-release fixing unit comprises a square first block and a second block that interlock with each other; the first block is directly fixed to the outer shell, and the circumferential edge of the first block extends outward to form a boss for interlocking; one side of the opposite sides of the second block is provided with a groove that interlocks with the boss, and the other side is provided with a hook groove pressure block that interlocks with the boss and can be opened and closed, when the hook groove pressure block is closed, the first block and the second block are interlocked, and when the hook groove pressure block is opened, the first block and the second block are separated; the other opposite sides of the second block are provided with limit blocks that limit the movement of the first block on the inside of the second block.

[0016] The hook groove pressing block is in a normally closed state. By pressing the hook groove pressing block, the first block can be placed into the second block or taken out from the second block, which realizes the need for quick disassembly and installation of the fitness pump from a fixed point.

[0017] Therefore, by using the quick-release fixing unit of the present invention, on the one hand, the fitness pump is not easy to fall off, which can meet the stable and reliable safety requirements; on the other hand, the fitness pump can be quickly installed and removed, which has a simple structure, is practical, and is indeed feasible.

[0018] As an optimal technical measure: the groove pressing block is rotatably connected to the second block via a rotating shaft, and a torsion spring is provided coaxially with the rotating shaft to keep the groove pressing block in a normally closed state.

[0019] As an optimal technical measure: the quick-release fixing unit includes a safety component; the safety component includes an abutment member with a flat surface provided on the hook groove pressure block, and a safety handle with a sloped surface rotatably provided on the second block; when the safety handle is closed, the flat part of the abutment member abuts against the sloped surface to completely prevent the rotation of the hook groove pressure block.

[0020] The safety assembly serves as a safety device, so that when the safety handle is in the closed state, the hook groove pressure block will never swing under the action of external force, thereby ensuring the absolute fastening of the first block and the second block, thereby ensuring the safety of the fitness pump.

[0024] After continuous exploration and testing, the utility model sets an elastic part between the motor unit and the outer shell. On the one hand, it effectively isolates the vibration and noise generated by the motor unit as a whole, and improves the user experience of the fitness pump; on the other hand, since the elastic part is used to fix the motor unit, the motor unit can produce a slight displacement relative to the outer shell when subjected to external force, forming a measuring object that can accurately reflect the magnitude of the tension on the pull wire at the outlet, creating conditions for accurately measuring the magnitude of the tension on the pull wire at the outlet, and the structure is simple and practical.

[0029] As preferred technical measures:

[0030] The force sensor is a strain gauge pressure sensor, a piezoresistive pressure sensor, a capacitive pressure sensor, or a piezoelectric pressure sensor, and there are one or more force sensors.

[0031] Strain-type pressure sensors mainly measure pressure by measuring the strain of elastic elements; piezoresistive pressure sensors are made of the piezoresistive effect of single-crystal silicon materials and integrated circuits; capacitive pressure sensors mainly use capacitors to convert the measured pressure into a pressure sensor with a changed capacitance value; piezoelectric pressure sensors use the piezoelectric effect, using electrical components and other machinery to convert pressure into electrical quantity, and then perform related measurement work. Technical personnel in this field can flexibly choose the instrument according to actual needs.

[0050] A fitness pump comprises an outer shell 1 with an inner cavity, and a motor unit arranged in the inner cavity of the outer shell 1;

[0051] An elastic member is provided between the fixed end of the motor unit and the inner wall of the outer shell 1 so that when the motor unit is subjected to an external force, it can generate a displacement relative to the outer shell 1 that can be used to measure tension and offset impact force.

[0052] In this embodiment, the outer shell 1 is a square shell or a circular shell or an arc shell or a triangular shell, and its inner cavity is equipped with a force sensor for measuring tension, and the force sensor is arranged adjacent to the motor unit and / or the elastic part; the elastic part is a spring or a rubber block 3 or a hydraulic rod or a pneumatic rod, and the number is one or more; the motor unit is a motor reducer unit 2.

[0053] In this embodiment, the force sensor is a strain gauge pressure sensor, a piezoresistive pressure sensor, a capacitive pressure sensor, or a piezoelectric pressure sensor, and there are one or more force sensors.

[0054] The second specific embodiment of the fitness pump of the present utility model:

The motor unit is a motor reduction box unit 2, which is fixed to the inner portion of the outer housing 1 by elastic members, so that the motor unit can be displaced relative to the outer housing 1 when subjected to an external force and return to its original position after the external force disappears.

[0056] The outer shell 1 is provided with a cable outlet 4, which is equipped with a force sensor. When the motor unit is subjected to tension from the cable 15, the force sensor measures the magnitude of the tension.

[0057] In this embodiment, the force sensor is a strain gauge pressure sensor including a strain gauge 5. The strain gauge 5 is mounted at the cable outlet 4 via a strain gauge seat.

When the hook and groove pressure block 10 is opened, the first block 6 and the second block 7 are separated. The second block 7 has limit blocks 11 on the other opposite sides that restrict the movement of the first block 6 inside the second block 7. The hook and groove pressure block 10 is in a normally closed state. Pressing the hook and groove pressure block 10 can place the first block 6 into or remove it from the second block 7, thus realizing the need for quickly removing and installing the fitness pump from the fixed point.
