Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a fan vehicle with adjustable wind resistance. Background Art

[0002] The fan bike is a kind of aerobic fitness equipment. Its exercise method is to generate power by stepping on the pedals, and at the same time increase the exercise intensity through the air resistance generated by the fan. This exercise method can effectively increase the heart rate and breathing rate, thereby achieving the effect of aerobic exercise. There are two forms of traditional fan bikes that change the air resistance: 1. The speed of the user's riding is generated. The faster the user rides, the greater the resistance, and the slower the user rides, the smaller the resistance; 2. Combination type, which is a combination of non-adjustable wind resistance and adjustable magnetic control resistance. The resistance generated by the above two types is not obvious, and the experience is not good.

[0003] Utility model patent CN206745848U proposes a fan car with adjustable resistance, including two magnets arranged opposite to each other and at a certain distance, and a metal disk arranged in the gap. During the movement, the metal disk cuts the magnetic lines of force in the gap between the two magnets, and the volume of the metal disk in the gap is changed by adjusting the relative position of the metal disk and the magnet, thereby changing the resistance formed by the magnet on the metal disk, so as to achieve the purpose of adjusting the resistance of the fan car by adjusting the magnetic control resistance. Since the adjustment range of the metal disk is limited, and the magnet not only forms a magnetic field in the above-mentioned gap, but also the magnetic lines of force extend outside the magnet, the resistance change of the fan car finally produced by moving the metal disk to adjust the magnetic control resistance is not obvious, which is not a good experience for users. Summary of the invention

[0004] The utility model aims to provide a fan vehicle with adjustable wind resistance, so as to solve the problem that the resistance adjustment of the existing fan vehicles is not obvious.

[0005] To achieve the above purpose, the technical solution of the utility model is: a fan vehicle with adjustable wind resistance, comprising: a vehicle frame, and

[0009] The blades are arranged to rotate on their own, with the rotation of the blades around the blade rotation axis as rotation. The rotation axes of the blades are located in the same plane, and the plane formed by the rotation axes of the blades is perpendicular to the rotation axis of the wind wheel. When the blades rotate on their own, their windward area increases or decreases accordingly, thereby increasing or decreasing the wind resistance.

[0010] And an operating mechanism is arranged in linkage with the blades and is used for driving the blades to rotate under the operation of the user.

[0011] Furthermore, the wind wheel includes a linkage part and a blade connection assembly fixedly connected to the linkage part. The blades are arranged around the wind wheel rotation axis through the blade connection assembly. The linkage part is linked to the pedal. When the pedal moves, the linkage part and the blades revolve to provide wind resistance for the movement. The blade connection assembly is a rotatable structure, so that the blades can rotate under the drive of the operating mechanism.

[0012] Furthermore, the blade connecting assembly includes a connecting sleeve and a rotating member. The outer side of the connecting sleeve is fixedly connected to the linkage member. The connecting sleeve is provided with a connecting hole for accommodating the rotating member. The rotating member is passed through the connecting hole and is rotatably connected to the connecting hole. The rotating member can rotate in the connecting hole with the blade rotation axis as the axis, and the rotating member is fixedly connected to the blade, thereby driving the blade to rotate.

[0013] Furthermore, the operating mechanism includes a sliding member, an operating member and a connecting rod assembly. The sliding member is slidably arranged relative to the wind wheel rotation axis. The operating member is connected to the sliding member and is used to drive the sliding member to slide relative to the wind wheel rotation axis. Each blade is connected to the sliding member through the connecting rod assembly, so that the blades, the sliding member and the connecting rod assembly form a connecting rod slider movement mechanism, so that when the sliding member slides relative to the wind wheel rotation axis, all blades on the wind wheel are driven to rotate simultaneously.

[0014] Furthermore, the connecting rod assembly includes a first connecting rod, a second connecting rod and a third connecting rod, one end of the first connecting rod is fixedly connected to the sliding member, and the other end is hinged to one end of the second connecting rod, the other end of the second connecting rod is hinged to one end of the third connecting rod, and the other end of the third connecting rod is fixedly connected to the blade, with the extension direction of the wind wheel rotation axis as the left and right direction, and the blade rotation axis direction of a single blade as the front and back direction, the sliding member slides in the left and right directions, and the connection point between the first connecting rod and the sliding member is arranged above the blade rotation axis. When the sliding member rotates to the left, it drives the blade to rotate counterclockwise.

[0015] Furthermore, the cross section of the blade is perpendicular to the blade rotation axis, and the cross section is large in the middle and small at both ends, thereby forming an inclined windward surface.

[0016] Furthermore, the cross section of the blade is elongated, and the maximum rotation angle of the blade is 90°.

[0017] Furthermore, the cross section of the blade is perpendicular to the blade rotation axis, and the aspect ratio of the cross section is 2 to 3.

[0018] Furthermore, the wind wheel and the pedal are linked by a belt transmission mechanism.

[0019] Furthermore, each of the handles is provided with a plurality of gripping portions, and the gripping portions are staggered in the front-rear and top-bottom directions.

[0020] The beneficial effects of the utility model are as follows: the utility model provides the user with adjustable motion resistance by arranging each blade to be capable of self-rotation and revolution around the wind wheel rotation axis, wherein the revolution provides wind resistance, the self-rotation adjusts the windward area of ​​the blade, and the wind resistance is adjusted by adjusting the size of the windward area; secondly, the method of adjusting the fan blades can effectively adjust the size of the windward area, and compared with magnetic resistance, the method of adjusting the resistance by adjusting the windward area is more obvious, that is, the resistance adjustment span is larger, and the user experience is better.

DETAILED DESCRIPTION

[0030] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0031] See also Figure 1-4 As shown, the utility model discloses a fan vehicle with adjustable wind resistance, including a frame 1, a pedal 2, a handle 3, a wind wheel 4 and an operating mechanism 5. Two pedals 2 are provided, which are arranged at intervals on the left and right sides of the frame 1, that is, a pedal 2 is provided on the left and right sides of the frame 1 respectively, and the pedal 2 is used for the user to step on and be driven by the user to move. Two handles 3 are provided, and the handles 3 are arranged in linkage with the pedal 2. The two handles 3 are arranged in intervals on the left and right sides of the frame 1, that is, a handle 3 is provided on the left and right sides of the frame 1 respectively, and the handles 3 are linked to the pedal 2 arranged on the same side as the handles 3. The handle 3 is arranged above the pedal 2, and the handle 3 is used for the user to hold and swing back and forth with the movement of the pedal 2. The wind wheel 4 is arranged in linkage with the pedal 2, and rotates with the movement of the pedal 2, thereby providing motion wind resistance. The wind wheel 4 and the pedal 2 are linked by a belt transmission mechanism. In this example, the wind wheel 4 is arranged at the front end of the frame 1, and is located between the two pedals 2 in the left and right directions. In other embodiments, the wind wheel 4 can also be arranged at other positions.

[0032] Each handle 3 is provided with two gripping parts 30, and the two gripping parts 30 are staggered in the front-back and up-down directions, so as to facilitate the selection of the user, thereby increasing the gears of the handle 3. The height and arm length of the user are different, and the position of the gripping part 30 of the handle 3 in the front-back and up-down directions is different, so that the user can choose the gripping part 30 that suits him. In other embodiments, each handle 3 can also be provided with one, three or more gripping parts 30. Providing one gripping part 30 can simplify the structure of the handle and have less impact on the movement of the user. Providing three or more gripping parts 30 can further refine the gears of the handle 3, and the user can more easily find the gear that suits him. However, the gripping part 30 occupies a large space, which will have a certain impact on the movement of the user. Therefore, in this example, two gripping parts 30 are provided on each handle 3 on the basis of taking into account the number and volume of gears.

[0033] The wind wheel 4 is provided with a plurality of blades 41 surrounding the wind wheel rotation axis 401. When the wind wheel 4 rotates, the blades 41 revolve around the wind wheel rotation axis 401. In addition, the blades 41 can also be arranged to rotate, with the rotation of the blades 41 around the blade rotation axis 402 as rotation. The blade rotation axes 402 are located in the same plane, and the plane formed by the blade rotation axes is perpendicular to the wind wheel rotation axis. When the blades rotate, their frontal area increases or decreases accordingly, thereby increasing or decreasing the wind resistance. In other embodiments, the blade rotation axis 402 of each blade 42 can also be on different planes, for example, staggered in the axial direction of the wind wheel rotation axis 401. The operating mechanism 5 is linked to the blade setting, and is used to drive the blades 41 to rotate under the operation of the user. It should be noted that the wind wheel rotation axis 401 and the blade rotation axis 402 described in the utility model are both virtual axes, and do not specifically refer to a certain part.

[0034] See also Figure 4-5 As shown, the wind wheel 4 includes a linkage 42 and a blade connection assembly 43 fixedly connected to the linkage 42, the blade 41 is connected to the blade connection assembly 43, and the blade 42 is arranged around the wind wheel rotation axis 401 through the blade connection assembly 43. The linkage 42 is rotatably arranged relative to the wind wheel rotation axis 401, so the rotation of the linkage 42 can drive the blade 41 to rotate, thereby realizing the revolution of the blade 41 to provide wind resistance for movement. The linkage 42 is linked to the pedal 2, more specifically, the linkage 42 is fixedly connected to the pulley 6 of the belt transmission mechanism, and the linkage 42 and the pulley 6 both rotate around the wind wheel rotation axis 401. When the pedal 2 moves, the pulley 6 and the linkage 42 rotate coaxially, thereby driving the blade 1 to revolve.

[0035] The blade connection assembly 43 is a rotatable structure, so that the blade 41 can rotate under the drive of the operating mechanism 5. Specifically, the blade connection assembly 43 includes a connection sleeve 431 and a rotating member 432. The outer side of the connection sleeve 431 is fixedly connected to the linkage member 42. The connection sleeve 431 is provided with a connection hole for accommodating the rotating member 432. The rotating member 432 is inserted into the connection hole. The connection hole is a round hole. The outer periphery of the rotating member 432 is cylindrical. Therefore, the rotating member 432 forms a rotatable connection with the connection hole. The rotating member 432 can rotate in the connection hole with the blade rotation axis 402 as the axis. The rotating member 432 is fixedly connected to the blade 41, thereby driving the blade 41 to rotate. The rotating member 432 and the blade 41 are connected via a U-shaped connecting plate 433. The blade 41 is clamped by the U-shaped connecting plate 433. The U-shaped connecting plate 433 is also fixedly connected to the rotating member 432. Therefore, when the rotating member 432 rotates, the blade 41 is driven to rotate via the U-shaped connecting plate 433, thereby realizing the self-rotation of the blade 41, thereby achieving the purpose of adjusting the windward area of ​​the blade 41.

[0036] See also Figure 4-5 As shown, the blade 41 extends along the direction of the blade rotation axis 402, and the cross section of the blade 41 is perpendicular to the blade rotation axis 402. The cross section of the blade 41 is slender, so that the change of the windward area during rotation is greater. Therefore, the larger the aspect ratio of the cross section of the blade 41, the larger the adjustable wind resistance span during rotation. However, too large an aspect ratio may cause the blade to withstand too much resistance and be damaged or even broken. Therefore, the aspect ratio of the cross section of the blade 41 is 2 to 3, preferably 2.5. The rotation angle of the blade 41 can be 0 to 360°. Since the cross section of the blade in this example is a symmetrical shape, the maximum rotation angle is 90° to achieve the theoretical wind resistance adjustment span. The cross-sectional shape of the blade 41 is preferably large in the middle and small at both ends, thereby forming an inclined windward surface, which is conducive to air flow and avoids damage to the blade 41.

[0037] However, the shape of the blade 41 is not limited to the shape described in this example. In other embodiments, the shape of the blade 41 can be a curved surface or an asymmetric surface. Accordingly, the maximum rotation angle of the blade 41 is not limited to 90°, as long as the size of the windward area can be changed by rotation.

[0038] See also Figure 3-6 As shown, the operating mechanism 5 includes a sliding member 51, an operating member 52 and a connecting rod assembly 53. The sliding member 51 is slidably arranged relative to the wind wheel rotation axis 401. The operating member 52 is connected to the sliding member 51 and is used to drive the sliding member 51 to slide relative to the wind wheel rotation axis 401. Each blade 41 is connected to the sliding member 51 through the connecting rod assembly 53, so that the blade 41, the sliding member 51 and the connecting rod assembly 53 form a connecting rod slider movement mechanism, so that when the sliding member 51 slides relative to the wind wheel rotation axis 401, all the blades 41 on the wind wheel are driven to rotate simultaneously, forming a linked rotation of the blades 41.

[0039] The sliding member 51 includes a first support 511, a second support 512, a sleeve 513 and a first bearing 514. The pulley 6 is connected to the wind wheel shaft 44 through two second bearings 60. The wind wheel shaft 44 is fixedly connected to the frame 1. The central axis of the wind wheel shaft 44 is the wind wheel rotating axis 401. The sleeve 513 is sleeved outside the wind rotor shaft 44, and the sleeve 513 and the wind rotor shaft 44 are slidably connected. The first support 511 is sleeved outside the sleeve 513 and forms a relatively fixed connection with the sleeve. The first bearing 514 is arranged between the sleeve 513 and the second support 512, and the inner ring of the first bearing 514 is relatively fixedly connected to the sleeve 513, and the outer ring of the first bearing 514 is relatively fixedly connected to the second support 512. Therefore, when the first support 511 is subjected to a force in the left and right directions, the sliding member 51 formed by the first support 511, the second support 512, the sleeve 513 and the first bearing 514 moves left and right relative to the wind rotor shaft 44, that is, the sliding member 51 and the wind rotor rotating shaft 401 form a relatively sliding matching relationship. In addition, the existence of the first bearing 514 allows the second support 512 to not only revolve with the blade 41, but also slide relative to the wind rotor rotating shaft 401 to drive the blade 41 to rotate.

[0040] See also Figure 3-6 As shown, the connecting rod assembly 53 includes a first connecting rod 531, a second connecting rod 532 and a third connecting rod 533. The first connecting rod 531 is a right angle. One end of the first connecting rod 531 is fixedly connected to the sliding member 51, specifically, fixed to the end surface of the sliding member 51, and the other end is hinged to one end of the second connecting rod 532. The other end of the second connecting rod 532 is hinged to one end of the third connecting rod 533. The other end of the third connecting rod 533 is fixedly connected to the blade 41. Figure 4 and Figure 6 In the embodiment, the blade 41 with the blade rotation axis 402 facing the front-to-back direction of the frame is taken as an example for explanation: the extension direction of the wind wheel rotation axis 401 is the left-right direction, which is also the left-right direction of the frame, and the direction of the blade rotation axis 402 of a single blade is the front-to-back direction, which is also the front-to-back direction of the frame. The sliding member 51 slides in the left-to-right direction, and the connection point between the first connecting rod 531 and the sliding member 51 is arranged above the blade rotation axis 402 relative to the blade rotation axis 402. When the sliding member 51 moves along the blade rotation axis 402, the first connecting rod 531 and the sliding member 51 are connected to the blade rotation axis 402. Figure 4 When the blade 41 slides to the left in the direction indicated by the straight arrow, Figure 4 In this example, the sliding member 51 is cylindrical, and there are four blades 41 , so there are also four first connecting rods 531 , which are arranged around the end surface of the sliding member 51 .

[0041] See also Figure 6As shown, the operating mechanism 5 also includes a force transmission member 54, which includes a first force transmission rod 541, a second force transmission rod 542 and a flexible force transmission rope 543. The first force transmission rod 541 is arranged at one end of the flexible force transmission rope 543, and the second force transmission rod 542 is arranged at the other end of the flexible force transmission rope 543. The first force transmission rod 541, the second force transmission rod 542 and the flexible force transmission rope 543 are all covered with a shell. The first force transmission rod 541, the second force transmission rod 542 and the flexible force transmission rope 543 are respectively slidably connected with the shell, and the shell can limit the movement direction of the first force transmission rod 541, the second force transmission rod 542 and the flexible force transmission rope 543 to avoid deformation of the flexible force transmission rope 543 during compression, thereby smoothly transmitting tension and pressure. When the operating member 52 pushes the first force transmission rod 541 in the direction of the flexible force transmission cable, the flexible force transmission cable 543 moves in the direction of the second force transmission rod 542, causing the second force transmission rod 543 to move away from the flexible force transmission cable 543, thereby driving the sliding member 51 to move leftward, causing the blade 41 to rotate counterclockwise. When the operating member 52 pulls the first force transmission rod 541, the flexible force transmission cable 543 is pulled to move in the direction of the first force transmission rod 541, causing the second force transmission rod 543 to move in the direction of the flexible force transmission cable 543, thereby driving the sliding member 51 to move rightward, causing the blade 41 to rotate clockwise.

[0042] The lower end of the force transmission member 54 is connected to the upper end of the first swing rod 551, and the lower end of the first swing rod 551 is coaxially connected to the lower end of the second swing rod 552. The lower end of the first swing rod 551 and the lower end of the second swing rod 552 are both connected to the swing shaft 553. The upper end of the second swing rod 553 is also connected to a pull rod 554, and the other end of the pull rod 554 is fixedly connected to the sliding member 51. When the second force transmission rod 542 moves downward, the first swing rod 551 swings counterclockwise, driving the swing shaft 553 to rotate along the Figure 6 The second swing rod 552 is rotated counterclockwise in the direction indicated by the middle arrow, thereby driving the second swing rod 552 to swing counterclockwise, and then driving the pull rod 554 and the sliding member 51 to move leftward, and finally realizing the counterclockwise rotation of the blade 41. In this example, the force transmission member 54 is a throttle cable, and the operating member 52 is a push handle. The push handle has a self-locking function, that is, it can be automatically locked when pushed to any angle, thereby locking the rotation angle of the blade 41. The specific structures of the throttle cable and the push handle are all existing technologies and will not be repeated here.

[0043] The working process of the utility model is as follows: Figure 2 and 3 As shown, the blades 41 of the wind wheel 4 are in state 1. At this time, the windward area of ​​the blades 41 is the smallest, and the wind resistance provided by the wind wheel is also the smallest. Figure 7 and 8As shown, the operating member 52 is pushed forward, and the force transmission member 54 is forced to move downward, so that the second force transmission rod 542 pushes the first swing rod 551 to swing counterclockwise, driving the second swing rod 552 to swing counterclockwise, and then driving the pull rod 554 and the sliding member 51 to move leftward, so as to realize the counterclockwise rotation of the blade 41 to increase the wind resistance. Among them, the rotation angle of the blade 41 is controlled by the operating member 52. When the wind resistance meets the user's requirements, the user only needs to stop the operating member 52, and the self-locking function of the operating member 52 can lock the angle of the blade 41. When it is necessary to reversely adjust the rotation of the blade 41 to reduce the wind resistance, just push the operating member 52 (push handle) in the reverse direction.
