Description

Magnetic resistance brake device

Technical Field

The present invention relates to a brake device for exercise equipment, and more particularly to a reluctance brake device in which a plurality of electromagnet assemblies are disposed adjacent to each other inside or outside a magnetic conductive ring.

Background

Modern people are leisure, compact and busy, and therefore are not available for outdoor sports. In recent years, most people tend to go to a gymnasium or sports center adjacent to a home instead to achieve the purpose of fitness and exercise by using fitness sports equipment (such as a flywheel bike, a treadmill or a step machine). In terms of the flywheel vehicle, a magnetic conduction piece is mainly sleeved on a flywheel connected with a vehicle body, and a plurality of magnetic resistance mechanisms are arranged on the outer periphery of the magnetic conduction piece to serve as loads for applying force during movement. When a user steps on a pedal of the flywheel vehicle to drive the flywheel to rotate, the magnetic force line between the magnetic conduction piece and the magnetic resistance mechanism is changed, so that the magnetic resistance mechanism generates braking force to prevent the flywheel from rotating, and the user needs to apply more force on the pedal to drive the flywheel to achieve the exercise effect of load training.

However, the existing reluctance mechanisms are all arranged on the flywheel support frame and are configured outside the flywheel frame, which not only causes the overall volume of the fitness exercise equipment to be too large, but also reduces the number of the reluctance mechanisms for reducing the volume, but also reduces the brake resistance to the flywheel.

Therefore, how to maintain the exercise equipment in a small volume and maintain sufficient braking resistance is an earnest desire of people, and is also an objective and direction for the related manufacturers to make efforts to develop and break through.

SUMMERY OF THE UTILITY MODEL

Therefore, an object of the present invention is to provide a reluctance brake apparatus, which is configured with a whole magnetic conductive ring on a rotating tray to replace the conventional magnetic conductive member, so as to increase the magnetic flux. In addition, the inner electromagnet assembly is arranged in the inner accommodating space of the magnetic conduction ring, and the outer electromagnet assembly can be arranged on the outer peripheral surface of the magnetic conduction ring, so that the braking resistance is greatly enhanced, and the number of the arranged outer electromagnet assemblies can be reduced even by the inner electromagnet assembly, so that the volume of the reluctance braking device is reduced.

It should be understood, however, that these implementation details are not to be interpreted as limiting the utility model. That is, in some embodiments of the utility model, these implementation details are not necessary. In addition, some conventional structures and elements are shown in simplified schematic form in the drawings for the sake of simplicity; and repeated elements will likely be referred to using the same reference numerals.

In addition, when an element (or a unit or a module, etc.) is "connected" to another element, it can mean that the element is directly connected to the other element or that the element is indirectly connected to the other element, i.e., that there is another element between the element and the other element. When an element is explicitly connected/coupled to another element, it means that there is no other element between the element and the other element. The terms first, second, third and the like are used for describing different elements only, and the elements themselves are not limited, so that the first element can be also called the second element. And the combination of elements/units/circuits herein is not a commonly known, conventional or existing combination in this field, and cannot be easily determined by a person skilled in the art whether the combination is easily accomplished by the person skilled in the art based on whether the elements/units/circuits are existing.

Referring to fig. 1, 2 and 3 together, fig. 1 is a front perspective view of a reluctance brake device 100 according to a first embodiment of the present invention; FIG. 2 is a rear perspective view of a reluctance brake device 100 according to a first embodiment of the present invention; FIG. 3 is an exploded view of the reluctance brake apparatus 100 of FIG. 1. As shown in fig. 1 to 3, the reluctance braking device 100 may be a part of a mechanism of an exercise apparatus (e.g., a flywheel, a treadmill, or a treadmill), and the reluctance braking device 100 includes a supporting member 110, a transmission shaft 120, a first cover 130, a rotating tray 140, a magnetic ring 150, a second cover 160, and at least one inner electromagnet member 170.

The supporting assembly 110 includes two supporting bases 111 disposed oppositely, and each supporting base 111 includes a shaft hole 1113. The transmission shaft 120 is pivoted to the shaft hole 1113 of each support seat 111. The first cover 130 is fixedly connected to one of the supporting bases 111 and is sleeved on the transmission shaft 120. The rotating tray 140 includes a through hole 141, and the transmission shaft 120 is disposed through the through hole 141. The magnetic ring 150 is disposed at one side of the rotating tray 140 and has an inner accommodating space 151. The second cover 160 is fixedly connected to the other support seat 111 and is sleeved with the rotating tray 140. The at least one inner electromagnet assembly 170 is disposed on the second cover 160 and located between the magnetic conductive ring 150 and the second cover 160, and the at least one inner electromagnet assembly 170 is located in the inner accommodating space 151. When the transmission shaft 120 is driven to rotate and is connected to drive the rotating tray 140 and the magnetic conductive ring 150 to rotate synchronously, the at least one inner electromagnet assembly 170 generates a reverse resistance relative to the rotation direction of the magnetic conductive ring 150.

Therefore, when the transmission shaft 120 is connected to drive the rotating tray 140 and the magnetic conductive ring 150 to rotate synchronously, the reluctance brake device 100 of the present invention can utilize the reverse resistance provided by the at least one inner electromagnet assembly 170 disposed in the magnetic conductive ring 150 to achieve the braking effect.

Specifically, the support assembly 110 may further include two connection assemblies 112. Each support seat 111 includes a first fixing portion 1111 and a second fixing portion 1112, wherein the first fixing portion 1111 is disposed with the shaft hole 1113, and the second fixing portion 1112 is vertically connected to the first fixing portion 1111. The second fixing portion 1112 is screwed to a frame body of the exercise device (not shown) to fix the supporting base 111 to the exercise device. Each connecting element 112 connects between two supporting bases 111, and includes a hexagon socket head cap screw 1121, a sleeve 1122, and a nut. Specifically, the hexagon socket screw 1121 passes through the positioning hole of the two first fixing portions 1111, and the sleeve 1122 is sleeved on the hexagon socket screw 1121 and located between the two first fixing portions 1111. The two support bases 111 are integrated by using a nut to lock one end of the socket head cap screw 1121.

In the first embodiment, the number of the at least one inner electromagnetic assemblies 170 is two, and each inner electromagnetic assembly 170 may include a brake core 171, a bobbin 172, an electromagnetic coil 173, and an input line 174. The brake core 171 may be a T-shaped core or a silicon steel member, one end of which is locked on the second cover 160, and the other end of which has a gap with the inner edge surface of the magnetic ring 150, wherein the gap may be 0.2 mm, but the utility model is not limited thereto. The winding bracket 172 is sleeved on the brake core 171. The solenoid 173 surrounds the bobbin 172 and is electrically connected to an input line 174. Input line 174 draws current from an external device and transmits the current to solenoid coil 173, thereby causing solenoid coil 173 to generate a magnetic field according to the principles of current magnetic effect. As the magnetic ring 150 rotates, the magnetic flux of the magnetic field experienced by the magnetic ring 150 increases over time. An induced current (i.e. eddy current) is formed according to the faraday's law of electromagnetic induction, and the induced current generates an induced magnetic field according to lenz's law to resist the magnetic flux of the magnetic field. The magnetic field of the inner electromagnet assembly 170 and the induced magnetic field of the rotating flux ring 150 are opposite in direction and repel each other. Therefore, the inner electromagnet assembly 170 will apply a reverse resistance to the rotating magnetic conductive ring 150 to brake the magnetic conductive ring 150, thereby providing the exercise effect of load training to the exercise equipment. In addition, in other embodiments, the number of the at least one inner electromagnet assembly may be multiple, and the inner electromagnet assemblies are uniformly distributed and locked on the second cover. Therefore, the reverse resistance generated by each internal electromagnet assembly can be uniformly applied to the magnetic conduction ring.

Referring to fig. 1-3 and 4 together, fig. 4 is a cross-sectional view of the reluctance brake apparatus 100 of fig. 1 along the cross-sectional line 4-4. As shown in fig. 1 to 4, the rotating tray 140 may further include a tray body 142 and a protrusion 143. The tray body 142 is fixed to the magnetic ring 150 by screws. The protrusion 143 is disposed on one side of the tray body 142 for fixedly connecting the magnetic conductive ring 150 and is accommodated in the second cover 160, and the through hole 141 penetrates through the tray body 142 and the protrusion 143.

In the first embodiment, the second cover 160 may include a die casting 161, a first positioning portion 162 and a second positioning portion 163. The first positioning portion 162 is disposed on one side of the die casting 161 and penetrates the other support seat 111. The second positioning portion 163 is disposed at the other side of the die cast 161 and is sleeved on the protrusion 143 of the rotating tray 140. In detail, the die casting 161, the first positioning portion 162 and the second positioning portion 163 are integrally formed, wherein the die casting 161 may have a circular shape, and an end surface of the die casting connected with the first positioning portion 162 is screwed to the other support seat 111.

In addition, the inner edge surface of the rotating tray 140 has a first groove 144, and the first groove 144 is connected to the through hole 141. The outer peripheral surface of the transmission shaft 120 has a second groove 121 and a third groove 122. The first groove 144 of the rotating tray 140 and the second groove 121 of the driving shaft 120 are aligned with each other. Specifically, reluctance brake device 100 may further comprise two

square keys

180a, 180b and a pulley 190. The pulley 190 is sleeved and fixed on one end of the transmission shaft 120 and has a fourth groove 191. The third groove 122 of the driving shaft 120 and the fourth groove 191 of the pulley 190 are aligned with each other. It should be noted that the square key 180a is accommodated between the third groove 122 and the fourth groove 191, and the square key 180b is accommodated between the first groove 144 and the second groove 121. When the user steps on the pedals of the exercise apparatus, the pedals are rotated via the belt driving pulley 190. Then, the belt pulley 190 is connected to drive the square key 180a, so that the square key 180a pushes against the transmission shaft 120 and drives the transmission shaft 120 to rotate synchronously; similarly, the transmission shaft 120 is connected to drive the square key 180b, so that the square key 180b pushes against the rotating tray 140 and drives the rotating tray 140 to rotate synchronously. Therefore, through the structural configuration of the belt pulley 190, the transmission shaft 120, the rotating tray 140 and the two

square keys

180a and 180b, the magnetic ring 150 can be linked and driven to rotate. Therefore, the present invention improves the magnetic flux received by the rotating tray 140 by disposing the magnetic ring 150 to replace the magnetic conductive member or the magnetic conductive sheet connected to the conventional flywheel.

Furthermore, the first cap 130 may include a first position-limiting groove 131, and the second cap 160 includes a second position-limiting groove 164. The reluctance brake device 100 may further include two C-shaped retaining rings 123 and two ball bearings 124. The two C-shaped retaining rings 123 are respectively embedded in the first limiting groove 131 and the second limiting groove 164. The two ball bearings 124 are respectively sleeved at two ends of the transmission shaft 120 and are adjacent to the two C-shaped retaining rings 123. Since the two ball bearings 124 sleeved on the transmission shaft 120 are respectively clamped by the two C-shaped retaining rings 123, the two ball bearings 124 are respectively limited inside the first cover 130 and the second cover 160. Thereby, the transmission shaft 120 is positioned on the two support seats 111 through the first sleeve cover 130 and the second sleeve cover 160.

Referring to fig. 5 and 6 together, fig. 5 is a perspective view of a reluctance braking device 200 according to a second embodiment of the present invention; FIG. 6 is an exploded view of magnetoresistive braking device 200 of FIG. 5. As shown in fig. 5 and 6, reluctance braking device 200 includes a supporting member 210, a transmission shaft 220, a first cover 230, a rotating tray 240, a magnetic ring 250, a second cover (not shown), at least one inner electromagnet member (not shown), and at least one outer electromagnet member 270. Specifically, except for supporting element 210 and at least one outer electromagnet element 270, other corresponding elements of reluctance brake device 200 of the second embodiment and reluctance brake device 100 of the first embodiment are the same, and therefore the structural configuration thereof is not repeated.

It should be noted that the second embodiment is different from the first embodiment in that the supporting member 210 includes two supporting bases 211 and a plurality of connecting members 212 disposed oppositely. The connecting elements 212 are disposed between the two supporting bases 211, and each connecting element 212 may include a socket head cap screw 2121 and two sleeves 2122. In addition, the magnetic ring 250 has an inner space (not shown) and an outer peripheral surface 252. At least one outer electromagnet assembly 270 is disposed between the two support bases 211 and adjacent to the outer peripheral surface 252 of the magnetic conductive ring 250. In this second embodiment, the number of outer electromagnet assemblies 270 is one, and may include a brake core 271, a bobbin 272, an electromagnetic coil 273 and an input line 274. The brake core 271 may be a core in a shape of a Chinese character 'shan' and has a gap with the outer peripheral surface 252 of the magnetic conductive ring 250, wherein the gap may be 0.2 mm, but the utility model is not limited thereto.

Specifically, the hexagon socket head cap screw 2121 is inserted into the fixing hole of the brake core 271. One of the sleeves 2122 is located between one side of the brake core 271 and one of the supporting bases 211, the other sleeve 2122 is located between the other side of the brake core 271 and the other supporting base 211, and both sleeves 2122 are sleeved on the socket head cap screws 2121. Therefore, the outer electromagnet assembly 270 can be fixedly connected between the two support bases 111 by locking one end of the socket cap screw 2121 with a nut. The winding bracket 272 is sleeved on the brake core 271. The electromagnetic coil 273 is disposed around the bobbin bracket 272 and electrically connected to the input line 274 to receive current and generate a magnetic field.

When the transmission shaft 220 is connected to drive the rotating tray 240 and the magnetic conductive ring 250 to rotate synchronously, any one of the at least one inner electromagnet assembly located in the inner accommodating space of the magnetic conductive ring 250 and the outer electromagnet assembly 270 located on the outer peripheral surface 252 of the adjacent magnetic conductive ring 250 generates a reverse resistance relative to the rotation direction of the magnetic conductive ring 250. Therefore, the inner electromagnet assembly and the outer electromagnet assembly 270 of the reluctance braking device 200 of the present invention can provide reverse resistance at the same time, so as to provide a larger braking resistance.

Referring to fig. 7 and 8 together, fig. 7 is a perspective view illustrating a reluctance braking device 300 according to a third embodiment of the present invention; FIG. 8 is a perspective view of second cover 360 of reluctance brake apparatus 300 of FIG. 7, wherein the left and right sides of FIG. 8 are viewed from different angles.

Specifically, except for second cover 360, other corresponding elements of reluctance brake device 300 of the third embodiment and reluctance brake device 200 of the second embodiment are the same, and therefore the configuration thereof is not repeated.

It should be noted that the third embodiment is different from the second embodiment in that the second cover 360 may further include a die casting 361, a first positioning portion 362 and a second positioning portion 363. The first positioning portion 362 is disposed on one side of the die casting 361 and penetrates through one of the supporting seats 311 of the supporting assembly 310. The second positioning part 363 is disposed on the other side of the die casting 361 and sleeved on the rotating tray 340. In detail, the die casting 361, the first positioning portion 362 and the second positioning portion 363 are integrally formed, wherein the die casting 361 may have a cross shape and the inner electromagnet assembly 370a is fastened thereto by screws. In addition, the second cover 360 may further include a plurality of fins 3631, and the fins 3631 are disposed around the second positioning portion 363. The inner electromagnet assembly 370a is disposed on two of the fins 3631 and connected to the end face of the die casting 361.

In other embodiments, the numbers of the inner electromagnet assemblies and the outer electromagnet assemblies of the reluctance brake device in the first to third embodiments of the disclosure can be selected according to the requirements of different exercise equipments or other devices. In addition, the die casting can be a frame body with any shape, and the brake iron core of each inner electromagnet assembly is arranged on the die casting.

In summary, the present invention has the following advantages: first, the inner electromagnet assembly and the outer electromagnet assembly can provide reverse resistance relative to the rotation direction of the magnetic conductive ring, so that the maximum brake resistance can be achieved under the condition of small volume. Secondly, the utility model replaces the magnetic conduction piece or the magnetic conduction sheet connected with the existing flywheel by arranging the magnetic conduction ring on the rotating tray so as to improve the received magnetic flux.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the utility model.
