Description
Technical Field
[0001] The utility model belongs to the technical field of simulated surfing practice equipment and relates to a surfing simulator. Background Art
[0002] Surfing is a good way of physical exercise, which can stimulate the cardiovascular system and the blood circulation of the whole body to achieve good fitness effects. However, this sport has strict requirements on objective conditions such as time and place and safety factors. Not everyone can fully enjoy the fun and fitness effects brought by surfing. Therefore, various functional surfing simulators have been produced on the market, which can improve body balance, coordination and kinesthetic sense, improve core strength and stability, effectively prevent injuries, and provide shaping training for users.
[0003] The existing surfing simulators on the market generally include four drive wheels and a surfboard arranged on the drive wheels. The four drive wheels are divided into two groups in pairs. The four fixing points on the left and right sides of the surfboard are respectively fixedly connected with the four drive wheels. The four drive wheels are driven by a motor to rotate synchronously, and at the same time, the surfboard can be driven to rise and fall back and forth and up and down. The user can stand on the surfboard to simulate surfing.
[0004] Such surfing simulators have the following disadvantages:
[0005] 1. Generally, the motor and the four drive wheels are connected by chain drive. However, the chains of the existing surfing simulators do not have a tensioning mechanism. If the chain is loose, it will cause tooth skipping, resulting in the surfboard shaking, poor acceleration, increased fuel consumption, and in severe cases, the motor may not be able to start.
[0006] 2. Among the four drive wheels, two drive wheels are coaxially arranged and fixedly connected by a transmission shaft. The two ends of this transmission shaft are respectively fixedly connected with the two drive wheels in the same group, and the middle part of the transmission shaft is connected with the surfboard. The two ends of the transmission shaft of the existing surfing simulator are welded and fixed to the drive wheels after installation. This welding fixing method will cause torsion at the two ends of the transmission shaft after the drive wheels rotate due to the installation position error, resulting in the vibration or even movement of the whole machine. Content of the Utility Model
[0007] The purpose of the utility model is to provide a surfing simulator with a tensioning mechanism for the above problems existing in the existing surfing simulators.
[0008] The purpose of the utility model can be realized by the following technical solutions:
[0009] A surfing simulator, comprising a base, a surfboard and a transmission assembly arranged on the base. Two groups of transmission assemblies are arranged symmetrically at intervals on the left and right. The transmission assembly includes two transmission wheels, and the left and right sides of the surfboard are respectively fixedly connected to each transmission wheel. One of the two transmission wheels in one group of transmission assemblies is drivingly connected through a first chain. A motor is further provided on the base, and the motor is drivingly connected to one of the transmission wheels in this transmission assembly through a second chain.
[0010] It is characterized in that a plurality of tensioning mechanisms are further provided on the base for tensioning the first chain and the second chain respectively. The tensioning mechanism includes a swing arm and a tensioning wheel. One end of the swing arm is rotatably arranged on the base, and the tensioning wheel is rotatably arranged at the other end of the swing arm. The tensioning mechanism further includes a limiting component, and the limiting component is used to limit the swing arm to swing in a single direction towards pressing the first chain or the second chain.
[0011] In the above-mentioned surfing simulator, the tensioning mechanism further includes a spring. One end of the spring is fixedly arranged on the base, and the other end is fixedly connected to the swing arm. The spring pulls the swing arm to make the tensioning wheel always elastically press on the first chain or the second chain.
[0012] In the above-mentioned surfing simulator, the limiting component includes a one-way bearing. A bearing seat is fixedly arranged on the base, and one end of the swing arm is rotatably arranged on the bearing seat through the one-way bearing. The swing arm can only swing in a single direction towards pressing the first chain or the second chain around the one-way axis.
[0013] In the above-mentioned surfing simulator, sprockets one are respectively fixedly arranged on the two transmission wheels in the transmission assembly drivingly connected to the motor. The sprockets one are coaxially arranged with the transmission wheels. The first chain is wound around the two sprockets one in this transmission assembly in a closed loop. A sprocket two is fixedly arranged on the output end of the motor, and a sprocket three is also fixedly arranged on the transmission wheel drivingly connected to the motor. The first chain is wound around the sprocket two and the sprocket three in a closed loop.
[0014] In the above-mentioned surfing simulator, between the two transmission wheels arranged coaxially in the two groups of transmission assemblies, they are fixedly connected through a transmission shaft. One end of the transmission shaft is fixedly welded to one of the transmission wheels, and the other end of the transmission shaft is movably connected to the other coaxial transmission wheel through a copper sleeve. The copper sleeve is fixedly arranged on the transmission wheel, and the transmission shaft is inserted into the inner hole of the copper sleeve.
[0015] In the above-mentioned surfing simulator, the tensioning wheel is made of rubber material.
[0016] In the above-mentioned surfing simulator, the outer edge of the tensioning wheel is embedded between the link plates of the first chain or the second chain.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] 1. A tensioning mechanism is added, and the one-way bearing design allows the swing arm to swing only in the direction of the chain compression, so that the chain is always in a tensioned state to prevent the chain from loosening;
[0019] 2. One end of the transmission shaft is welded and fixed, and the other end is fixed by a copper sleeve. However, there is still a certain gap between the transmission shaft and the copper sleeve to allow a small displacement of the transmission shaft to avoid vibration or movement caused by welding the two ends.
[0020] 3. The tension wheel is made of rubber material, which can achieve a silent effect and reduce the noise when the machine is running; by embedding the outer edge of the tension wheel between the chain plates of the chain, it can prevent the tension wheel from detaching from the chain during chain operation.

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0027] like Figure 1 and Figure 2 As shown, a surfing simulator described in the utility model comprises a base 1, a surfboard 2 and a transmission assembly arranged on the base 1, two groups of transmission assemblies are spaced apart and symmetrically arranged on the left and right sides, the transmission assembly comprises two transmission wheels 3, and the left and right sides of the surfboard 2 are respectively fixedly connected to the transmission wheels 3; the two transmission wheels 3 in one group of transmission assemblies are connected by a chain 1 4, and a motor 6 is further provided on the base 1, and the motor 6 is connected to one of the transmission wheels 3 in the transmission assembly by a chain 2 5.
[0028] like Figure 3As shown, a number of tensioning mechanisms are also provided on the base 1 for tensioning the first chain 4 and the second chain 5 respectively. The tensioning mechanism includes a swing arm 7 and a tensioning wheel 8. One end of the swing arm 7 is rotatably arranged on the base 1, and the tensioning wheel 8 is rotatably arranged at the other end of the swing arm 7. The tensioning mechanism also includes a spring 14. One end of the spring 14 is fixedly arranged on the base 1, and the other end is fixedly connected to the swing arm 7. The spring 14 pulls the swing arm 7 so that the tensioning wheel 8 is always elastically pressed against the first chain 4 or the second chain 5.
[0029] The tensioning mechanism also includes a limiting component, which is used to limit the swing of the swing arm 7 in a single direction towards pressing the first chain 4 or the second chain 5. The limiting component includes a one-way bearing. A bearing seat 15 is fixedly arranged on the base 1, and one end of the swing arm 7 is rotatably arranged on the bearing seat 15 through the one-way bearing. The swing arm 7 can only swing in a single direction towards pressing the first chain 4 or the second chain 5 around the one-way axis.
[0030] On two transmission wheels 3 in the transmission component connected to the motor in a transmission manner, a first sprocket 9 is respectively fixedly arranged. The first sprocket 9 is arranged coaxially with the transmission wheel 3. The first chain 4 is closed and wound around the two first sprockets 9 of the transmission component; a second sprocket 10 is fixedly arranged on the output end of the motor 6, and a third sprocket 11 is also fixedly arranged on the transmission wheel 3 connected to the motor 6 in a transmission manner. The first chain 4 is closed and wound around the second sprocket 10 and the third sprocket 11.
[0031] As Figure 4 shown, between two transmission wheels 3 arranged coaxially in two groups of transmission components, they are fixedly connected by a transmission shaft 12. One end of the transmission shaft 12 is fixedly welded to one of the transmission wheels 3, and the other end of the transmission shaft 12 is movably connected to the other transmission wheel 3 arranged coaxially through a copper sleeve 13. The copper sleeve 13 is fixedly arranged on the transmission wheel 3, and the transmission shaft 12 is inserted into the inner hole of the copper sleeve 13. One end of the transmission shaft 12 is fixedly welded, and the other end is fixedly fitted through the copper sleeve 13. However, there is still a certain gap between the transmission shaft 12 and the copper sleeve 13, which can allow a small displacement of the transmission shaft 12 to avoid vibration or movement caused by welding both ends dead.
[0032] The tensioning wheel 8 is made of rubber material, which can achieve the effect of noise reduction and reduce the noise during the operation of the machine. The outer edge of the tensioning wheel 8 is embedded between the link plates of the first chain 4 or the second chain 5 and abuts against the bush of the chain, which can prevent the tensioning wheel 8 from separating from the chain during the operation of the chain.
