Description

Technical Field

[0001] This disclosure relates to the technical field of fitness training equipment, and in particular to a leg training bed. Background Technology

[0002] A leg training bed is a bed-shaped fitness training device used to assist users in performing leg exercises. Leg training beds are widely used in gyms, hotel leisure centers, sports training centers, rehabilitation centers, parks, and local hospitals.

[0003] The related technology of leg training bed includes a main body and a leg slide assembly. The leg slide assembly is slidably connected to the main body. A spring is provided between the leg slide assembly and the main body. The user's legs are used to push against the leg slide assembly, so that the leg slide assembly slides relative to the main body to perform leg training. That is, the user's legs perform leg training by overcoming the interaction force between the leg slide assembly and the spring, such as Chinese patent with patent number CN202311016449.2.

[0004] However, because the user's legs are used to push against the leg slide assembly, which slides relative to the main body of the device for leg training, the user's legs overcome the interaction force between the leg slide assembly and the spring to train their legs. The thrust generated by the legs is used to overcome the force generated by the spring, which makes it more strenuous for the user to perform leg training. This makes it more difficult for the user's legs to compress the spring through the leg slide assembly, resulting in more intense movements and a higher training intensity for the user during leg training. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a leg training bed that allows users to perform leg training with lower intensity.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A leg training bed, comprising:

[0008] The main body of the bed has an installation cavity and a sliding groove, and the installation cavity is connected to the sliding groove.

[0009] A training drive device is located inside the mounting cavity and connected to the bed body;

[0010] The leg support assembly is connected to the power output end of the training drive device via the sliding groove. The training drive device is used to drive the leg support assembly to reciprocate relative to the bed body along the extension direction of the sliding groove, so that the leg support assembly reciprocates relative to the bed body.

[0011] In one embodiment, the training drive device includes a fixed base, a training drive mechanism, and a sliding part. The training drive mechanism is mounted on the fixed base. The fixed base has a connecting groove that communicates with both the mounting cavity and the sliding groove. A portion of the sliding part is located within the connecting groove and is slidably connected to the fixed base. The sliding part is connected to the power output end of the training drive mechanism, which drives the sliding part to reciprocate relative to the fixed base. The sliding part is connected to the leg support assembly, and the fixed base is connected to the bed body.

[0012] In one embodiment, the training drive mechanism includes a training drive motor and a connecting screw. The connecting screw is located in the connecting groove and rotatably connected to the fixed base. The training drive motor is mounted on the fixed base, and the power output end of the training drive motor is connected to the connecting screw. The training drive motor is used to drive the connecting screw to rotate relative to the fixed base. The sliding part has an internal threaded hole communicating with the connecting groove. The connecting screw passes through the internal threaded hole and is screwed to the sliding part.

[0013] In one embodiment, the training drive mechanism further includes a belt drive assembly, which includes a drive pulley, a transmission belt, and a driven pulley. The drive pulley is mounted on the power shaft of the training drive motor, the driven pulley is sleeved on the connecting screw, and the transmission belt is respectively sleeved on the drive pulley and the driven pulley.

[0014] In one embodiment, the leg support assembly includes a support body and a connecting part connected together, the support body being located outside the sliding groove, and the connecting part being connected to the sliding part through the sliding groove.

[0015] In one embodiment, the supporting body includes a foot pedal and an extension connected together, with one end of the extension opposite to the foot pedal connected to the connecting part.

[0016] In one embodiment, the connecting portion is welded to the sliding portion.

[0017] In one embodiment, the leg training bed further includes a control display component connected to the bed body, and the training drive motor is electrically connected to the control display component.

[0018] In one embodiment, the leg training bed further includes a first position sensor and a second position sensor. The first position sensor is connected to one end of the fixed base, and the second position sensor is connected to the other end of the fixed base. The sliding part is provided with a sensing plate, and the sensing plate, the first position sensor, and the second position sensor are all electrically connected to the control and display component. When the sliding part slides relative to the fixed base to a first position, the first position sensor senses the sensing plate. When the sliding part slides relative to the fixed base to a second position, the second position sensor senses the sensing plate.

[0019] In one embodiment, the control display component includes a touch display and a mounting base. The touch display is connected to the mounting base, and the mounting base is connected to the bed body. The training drive motor, the sensing plate, the first position sensor, and the second position sensor are all electrically connected to the touch display.

[0020] Compared with the prior art, this disclosure has at least the following advantages:

[0021] 1. Since the main body of the bed is for the user to lie flat, the leg support component is used to support the legs so that the user's legs can be placed on the leg support component. The training drive device is used to drive the leg support component to reciprocate relative to the main body of the bed along the extension direction of the sliding groove. This reciprocating motion of the leg support component relative to the main body of the bed causes the user's legs to repeatedly flex and extend with the reciprocating motion of the leg support component. This allows the user's legs to repeatedly extend and retract along the extension direction of the sliding groove, thereby completing the user's leg training.

[0022] 2. Because the training drive device is used to drive the leg support component to reciprocate relative to the main body of the bed along the extension direction of the sliding groove, so that the user's legs repeatedly flex and extend with the reciprocating motion of the leg support component, and the user's legs repeatedly extend and retract along the extension direction of the sliding groove, compared with the existing leg training beds, the leg training bed disclosed herein avoids the problem that the user's legs have difficulty compressing the spring through the leg slide component in the existing technology, so that the user does not have to exert effort when performing leg training, and the user's legs can more easily push the leg support component under the action of the training drive device, so that the user's movement is gentler when performing leg training, and thus the training intensity is lower.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figures 1 to 5 As shown, a leg training bed 10 of one embodiment includes a bed body 100, a training drive device 200, and a leg support assembly 300. The bed body 100 has an installation cavity 110 and a sliding groove 120, and the installation cavity 110 and the sliding groove 120 are connected. The training drive device 200 is located in the installation cavity 110 and connected to the bed body 100. The leg support assembly 300 is connected to the power output end of the training drive device 200 through the sliding groove 120. The training drive device 200 is used to drive the leg support assembly 300 to reciprocate relative to the bed body 100 along the extension direction of the sliding groove 120, so that the leg support assembly 300 reciprocates relative to the bed body 100.

[0033] In this embodiment, the bed body 100 is used for the user to lie flat. The leg support assembly 300 is used to support the user's legs. The leg support assembly 300 is connected to the power output end of the training drive device 200 through a sliding groove 120, that is, a part of the leg support assembly 300 extends into the mounting cavity 110 through the sliding groove 120 and is connected to the power output end of the training drive device 200.

[0034] The aforementioned leg training bed 10, with the bed body 100 for the user to lie flat, and the leg support component 300 for supporting the legs, allows the user's legs to be placed on the leg support component 300. The training drive device 200 drives the leg support component 300 to reciprocate relative to the bed body 100 along the extension direction of the sliding groove 120, so that the leg support component 300 reciprocates relative to the bed body 100, causing the user's legs to repeatedly flex and extend with the reciprocating movement of the leg support component 300, thereby causing the user's legs to repeatedly extend and retract along the extension direction of the sliding groove 120, thus completing the user's leg training.

[0035] Since the training drive device 200 is used to drive the leg support component 300 to reciprocate relative to the bed body 100 along the extension direction of the sliding groove 120, so that the user's legs repeatedly flex and extend with the reciprocating motion of the leg support component 300, and the user's legs repeatedly extend and retract along the extension direction of the sliding groove 120, compared with the leg training bed 10 of the prior art, the leg training bed 10 disclosed herein avoids the problem that the user's legs are difficult to compress the spring through the leg slide component in the prior art, so that the user does not have to exert effort when performing leg training, and the user's legs can more easily push the leg support component 300 under the action of the training drive device 200, so that the user's movement is gentler when performing leg training, and thus the training intensity is lower.

[0036] like Figures 1 to 5As shown, in one embodiment, the training drive device 200 includes a fixed base 210, a training drive mechanism 220, and a sliding part 230. The training drive mechanism 220 is installed on the fixed base 210. The fixed base 210 has a connecting groove 211, which communicates with the mounting cavity 110 and the sliding groove 120 respectively. Part of the sliding part 230 is located in the connecting groove 211 and is slidably connected to the fixed base 210. The sliding part 230 is connected to the power output end of the training drive mechanism 220. The training drive mechanism 220 is used to drive the sliding part 230 to slide back and forth relative to the fixed base 210. The sliding part 230 is connected to the leg support assembly 300, and the fixed base 210 is connected to the bed body 100. In this embodiment, the training drive mechanism 220 is used to drive the sliding part 230 to slide back and forth relative to the fixed base 210. The sliding part 230 is connected to the leg support assembly 300 so that the sliding part 230 drives the leg support assembly 300 to slide back and forth relative to the fixed base 210, thereby improving the sliding performance of the leg support assembly 300.

[0037] like Figures 2 to 5 As shown, in one embodiment, the training drive mechanism 220 includes a training drive motor 221 and a connecting screw 222. The connecting screw 222 is located in the connecting groove 211 and rotatably connected to the fixed base 210. The training drive motor 221 is mounted on the fixed base 210, and the power output end of the training drive motor 221 is connected to the connecting screw 222. The training drive motor 221 is used to drive the connecting screw 222 to rotate relative to the fixed base 210. The sliding part 230 has an internal threaded hole 231 communicating with the connecting groove 211. The connecting screw 222 passes through the internal threaded hole 231 and is screwed to the sliding part 230. In this embodiment, the training drive motor 221 drives the connecting screw 222 to rotate relative to the fixed base 210 via the belt drive assembly 223. When the training drive motor 221 is working, it drives the connecting screw 222 to rotate, thereby causing the sliding part 230 to slide within the connecting groove 211. This, in turn, causes the leg support assembly 300 to slide back and forth along the extension direction of the sliding groove 120, making it easy for the leg training bed 10 to meet the requirements of automated training. In this embodiment, the training drive motor 221 is a servo motor.

[0038] like Figures 4 to 5As shown, in one embodiment, the training drive mechanism 220 further includes a belt drive assembly 223. The belt drive assembly 223 includes a drive wheel 2231, a transmission belt 2232, and a driven wheel 2233. The drive wheel 2231 is mounted on the power shaft of the training drive motor 221, and the driven wheel 2233 is sleeved on the connecting screw 222. The transmission belt 2232 is respectively sleeved on the drive wheel 2231 and the driven wheel 2233, so that the training drive motor 221 drives the connecting screw 222 to rotate relative to the fixed base 210 through the drive wheel 2231, the transmission belt 2232, and the driven wheel 2233, thereby making the transmission reliability of the training drive mechanism 220 high.

[0039] It is understood that in other embodiments, the training drive motor 221 is not limited to driving the connecting screw 222 to rotate relative to the fixed base 210 via the belt drive assembly 223. For example, the training drive motor 221 drives the connecting screw 222 to rotate relative to the fixed base 210 via a gear assembly. Alternatively, the power shaft of the training drive motor 221 may be connected to the connecting screw 222 via a coupling to drive the connecting screw 222 to rotate relative to the fixed base 210.

[0040] like Figures 1 to 3 As shown, in one embodiment, the leg support assembly 300 includes a support body 310 and a connecting part 320 connected together. The support body 310 is located outside the sliding groove 120, and the connecting part 320 is connected to the sliding part 230 through the sliding groove 120. In this embodiment, the support body 310 has a support groove 311, which is adapted to fit the user's foot to facilitate the placement of the user's foot; the connecting part 320 is connected to the sliding part 230 through the sliding groove 120, that is, the connecting part 320 extends into the mounting cavity 110 through the sliding groove 120 and is connected to the sliding part 230, so that the connection between the connecting part 320 and the sliding part 230 is convenient.

[0041] like Figure 1 and Figure 3 As shown, in one embodiment, the support body 310 includes a foot pedal 312 and an extension 313 connected together. One end of the extension 313, away from the foot pedal 312, is connected to a connecting portion 320. In this embodiment, the foot pedal 312 and the extension 313 are integrally formed, resulting in high structural strength between them. The extension 313 is welded to the connecting portion 320, resulting in high connection strength between them. Furthermore, the support body 310 is L-shaped, allowing it to better support the user's legs.

[0042] like Figure 3As shown, in one embodiment, the connecting portion 320 is welded to the sliding portion 230, so that the connection strength between the connecting portion 320 and the sliding portion 230 is better.

[0043] like Figures 1 to 2 As shown, in one embodiment, the leg training bed 10 further includes a control display component 400, which is connected to the bed body 100, and the training drive motor 221 is electrically connected to the control display component 400. In this embodiment, the training drive motor 221 is electrically connected to the control display component 400 so that the user can set the drive parameters of the training drive motor 221 according to the user's needs, making it easier for the user to adjust the training intensity during leg training.

[0044] like Figures 2 to 4 As shown, in one embodiment, the leg training bed 10 further includes a first position sensor 500 and a second position sensor 600. The first position sensor 500 is connected to one end of the fixed base 210, and the second position sensor 600 is connected to the other end of the fixed base 210. The sliding part 230 is provided with a sensing plate 232. The sensing plate 232, the first position sensor 500, and the second position sensor 600 are all electrically connected to the control and display component 400. When the sliding part 230 slides relative to the fixed base 210 to the first position, the first position sensor 500 senses the sensing plate 232. 32. At this time, the sliding part 230 is located in the first stroke position. When the sliding part 230 slides to the second position relative to the fixed base 210, the second position sensor 600 senses the sensing plate 232. At this time, the sliding part 230 is located in the second stroke position, so that the sliding part 230 slides back and forth between the first stroke position and the second stroke position under the action of the training drive mechanism 220. This causes the sliding part 230 to drive the leg support component 300 to slide back and forth between the first stroke position and the second stroke position, thereby making the limiting effect of the training drive device 200 on the leg support component 300 better.

[0045] It should be noted that the method of controlling the training drive motor 221 by the control display component 400, the working principle between the first position sensor 500 and the sensing plate 232, and the working principle between the second position sensor 600 and the sensing plate 232 are all existing technologies. This disclosure only protects the connection relationship and position relationship of the above-mentioned components.

[0046] like Figures 1 to 4As shown, in one embodiment, the control display assembly 400 includes a touch display 410 and a mounting base 420. The touch display 410 is connected to the mounting base 420, which is connected to the bed body 100. The training drive motor 221, the sensing plate 232, the first position sensor 500, and the second position sensor 600 are all electrically connected to the touch display 410. In this embodiment, the mounting base 420 is welded to the bed body 100, resulting in a strong connection between the mounting base 420 and the bed body 100.

[0047] like Figures 1 to 2 As shown, in one embodiment, the leg training bed 10 also includes a guardrail assembly 700, which is connected to the bed body 100 to prevent the user from falling off the bed body 100, so that the guardrail assembly 700 provides better protection for the user.

[0048] like Figures 1 to 2 As shown, in one embodiment, the bed body 100 is provided with a waist sleeve 130, which is used to wrap around the user's waist and play a good role in limiting the user's waist, further preventing the user from falling off the bed body 100.

[0049] like Figures 1 to 2 As shown, in one embodiment, the leg training bed 10 also includes a headrest 800, which is connected to the bed body 100. The lumbar support 130 is located between the headrest 800 and the leg support component 300. The user's head is used to press against the headrest 800, which makes the user more comfortable during leg training.

[0050] Compared with the prior art, this disclosure has at least the following advantages:

[0051] 1. Since the bed body 100 is for the user to lie flat, the leg support component 300 is used to support the legs so that the user's legs can be placed on the leg support component 300. The training drive device 200 is used to drive the leg support component 300 to reciprocate relative to the bed body 100 along the extension direction of the sliding groove 120, so that the leg support component 300 reciprocates relative to the bed body 100, and the user's legs repeatedly flex and extend with the reciprocating movement of the leg support component 300, thereby making the user's legs repeatedly extend and retract along the extension direction of the sliding groove 120, thus completing the user's leg training.

[0052] 2. Since the training drive device 200 is used to drive the leg support component 300 to reciprocate relative to the bed body 100 along the extension direction of the sliding groove 120, so that the user's legs repeatedly flex and extend with the reciprocating motion of the leg support component 300, and the user's legs repeatedly extend and retract along the extension direction of the sliding groove 120, compared with the leg training bed 10 of the prior art, the leg training bed 10 disclosed herein avoids the problem that the user's legs are difficult to compress the spring through the leg slide component in the prior art, so that the user is less effort when performing leg training, and the user's legs can more easily push the leg support component 300 under the action of the training drive device 200, so that the user's movement is gentler when performing leg training, and thus the training intensity is lower.

[0053] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
