It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The embodiment of the application provides rehabilitation training equipment. Rehabilitation training devices are devices that help patients develop passive exercises and daily activities to promote patient recovery. The patient can carry out rehabilitation training after wearing the rehabilitation training device as a wearer. The rehabilitation training performed by the wearer can be performed on the lower limb or the upper limb, and the embodiment of the application is not limited to this.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a rehabilitation training device according to an embodiment of the present application. The rehabilitation training device may include a support apparatus 100 and a training aid 500.

In performing the training aid, the training aid 500 may be fastened to the body of the wearer by wearing to assist and drive the wearer to perform rehabilitation training. For example, the auxiliary training device 500 may be worn to one or more of the user's lower limbs, upper limbs, torso, or hips, as the embodiments of the present application are not limited in this regard.

As shown in fig. 1, the support device 100 may be coupled to an auxiliary training device 500 to provide support to the wearer through the auxiliary training device 500 during rehabilitation training of the wearer. The support device 100 may also be unconnected to the training aid 500, the support device 100 being intended for the wearer to rest against to provide support to the wearer. Of course, the support device 100 may also be configured to provide support by being coupled to the auxiliary training device 500, while also being directly supported by the wearer, as the embodiments of the present application are not limited in this respect.

As shown in fig. 1, the support device 100 may include a base frame 10, a support assembly 20, a first adjustment assembly 30, and a battery assembly 40.

Illustratively, the chassis 10 can be placed onto a support surface to provide support force for the entire support device 100. The first adjusting assembly 30 is disposed on the base frame 10 and is connected to the supporting assembly 20. Further, the support assembly 20 may be adjusted to a proper position by the first adjustment assembly 30. The support assembly 20 is capable of providing support to the wearer after being adjusted to the proper position. For example, support assembly 20 can be coupled to auxiliary exercise device 500 and/or be supported by the wearer. The battery assembly 40 is connected to the chassis 10 and is capable of powering the support device 100 or rehabilitation training device.

Referring to fig. 2-6, fig. 2 is a schematic view of a portion of a structure of a supporting device provided in an embodiment of the present application, fig. 3 is a schematic view of a battery taking-out state of the supporting device shown in fig. 2, fig. 4 is a schematic view of a connection structure of a battery compartment, a chassis and a locking mechanism of the supporting device shown in fig. 2, fig. 5 is an exploded view of a battery and a battery compartment of the battery assembly 40 provided in an embodiment of the present application, and fig. 6 is a schematic view of a structure of another view of the battery shown in fig. 5.

As shown in fig. 2 and 3, the battery assembly 40 may include a battery compartment 42 and a battery 43.

Illustratively, the battery compartment 42 is coupled to the chassis 10, and the battery compartment 42 is movable in a first direction relative to the chassis 10. The battery compartment 42 has a first cavity 421, and at least one side outer wall of the battery compartment 42 forming the first cavity 421 has a first opening 422. The battery 43 can be at least partially housed within the first cavity 421 and move with the battery compartment 42. When the battery 43 is at least partially received in the first cavity 421, the battery 43 is capable of supplying power to the rehabilitation training device. The battery 43 is able to pass through the first opening 422 in a second direction to enter or leave the first cavity 421, the first direction and the second direction being different.

It will be appreciated that the battery compartment 42 is coupled to the chassis 10 and is movable in a first direction relative to the chassis 10, and that the battery 43 may be loaded into the battery compartment 42 or unloaded from the battery compartment 42 in a second direction, which is different from the first direction. Therefore, the battery compartment 42 is used as a carrier for the battery 43, and the battery 43 can be installed in the preset position of the chassis 10 after at least two direction changes, or the battery 43 is detached from the preset position of the chassis 10, so that the supporting device 100 can reasonably layout the installation position of the battery 43 according to the actual structure, and finally the supporting device 100 and the whole rehabilitation training device have more compact structure and less occupied space.

In a first embodiment where battery 43 powers the rehabilitation training device: the battery 43 is provided with a second power connection 431; when the battery 43 is at least partially accommodated in the battery compartment 42, the battery 43 is electrically connected to the rehabilitation training device through the second power connector 431.

For example, the battery assembly 40 further includes a first power connector 41 provided on the battery compartment 42, the first power connector 41 being capable of moving synchronously with the battery compartment 42, and the first power connector 41 being electrically connected to the rehabilitation training device at all times. When the battery 43 is at least partially accommodated in the battery compartment 42, the second power connector 431 is electrically connected to the first power connector 41. Because the battery 43 and the first power connector 41 all follow the movement of the battery compartment 42, when the battery 43 is at least partially accommodated in the battery compartment 42, even if the battery compartment 42 moves, the battery 43 can be always electrically connected with the rehabilitation training device through the second power connector 431, so that the battery 43 can supply power to the rehabilitation training device.

In a second embodiment where battery 43 powers the rehabilitation training device: the battery 43 is provided with a second power connector 431, and when the battery compartment 42 is moved to the first position, the battery 43 follows the movement of the battery compartment 42 and is electrically connected to the rehabilitation training device through the second power connector 431.

For example, the battery assembly 40 further includes a first power connector 41 movably connected with the battery compartment 42, the first power connector 41 is fixed with the chassis 10, and the first power connector 41 is always electrically connected with the rehabilitation training device. Therefore, when the battery compartment 42 moves to the first position, the battery 43 follows the battery compartment 42 to move to the second power connector 431 to be electrically connected with the first power connector 41, and the battery 43 is further electrically connected with the rehabilitation training device through the second power connector 431. When the battery compartment 42 is moved to the second position, the battery 43 follows the movement of the battery compartment 42 to the second power connection 431 to be separated from the first power connection 41, and the battery 43 stops supplying power to the rehabilitation training device through the second power connection 431.

It should be noted that, the above-mentioned battery 43 supplies power for the rehabilitation training device, the battery 43 may supply power for the whole rehabilitation training device alone, the battery 43 may supply power for the supporting device 100 of the rehabilitation training device alone, the battery 43 may cooperate with other power sources to supply power for the supporting device 100 or other electric parts of the rehabilitation training device together, which is not limited in this embodiment of the present application, so long as the technical scheme that the battery 43 can supply power for at least part of the electric elements of the rehabilitation training device is within the scope of the embodiment of the present application. Hereinafter, the battery 43 can supply power to at least part of the electrically powered elements of the rehabilitation training device or to the entire rehabilitation training device, simply referred to as the battery supplying power to the rehabilitation training device.

Alternatively, the first direction may be perpendicular to the supporting surface, the second direction is perpendicular to the supporting surface, and the second direction is perpendicular to the first direction, or the first direction may be parallel to the supporting surface, the second direction is perpendicular to the supporting surface, and the second direction is perpendicular to the first direction, or the first direction is perpendicular to the supporting surface, the second direction is perpendicular to the second supporting surface, and the second direction is inclined to the first direction, where of course, the first direction and the second direction may be parabolic, involute, etc., which is not limited in this application, as long as the different technical schemes of the first direction and the second direction are all within the protection scope of the application.

In the following, taking the example that the first direction is approximately parallel to the supporting surface and the second direction is approximately perpendicular to the supporting surface, the working principle of the technical solution of the embodiment of the present application is further explained and illustrated in combination with the replacement procedure of the battery 43:

first, when the battery compartment 42 is in the second position, the first opening 422 of the battery compartment 42 is located on a side of the battery compartment 42 facing away from the support surface. Also, the first opening 422 and the chassis 10 are offset from each other in the first direction, i.e., the direction parallel to the supporting surface, such that the first opening 422 is not shielded by the chassis 10 and the first power connector 41 and the second power connector 431 are separated. At this time, the battery 43 in the battery compartment 42 may be taken out from the battery compartment 42 after passing through the first opening 422 in the second direction, and another battery 43 may be placed in the battery compartment 42 after passing through the first opening 422 in the second direction.

The battery compartment 42 is then moved in a first direction such that the battery compartment 42 is moved to a first position. When the battery compartment 42 is in the first position, the first opening 422 can be at least partially obscured by the chassis 10 to restrict the second battery 43 from passing through the first opening 422 in the second direction. At this time, the first power connector 41 and the second power connector 431 are connected so that the battery 43 can supply power to the rehabilitation training device.

It can be seen that, in the embodiment of the present application, the battery assembly 40 may implement the battery 43 taking and placing into the battery compartment 42 through the first opening 422, and then the battery 43 may be quickly moved by the battery compartment 42 to connect or disconnect the first power connector 41 and the second power connector 431.

It will be appreciated that the battery compartment 42 is coupled to the chassis 10 and is movable in a first direction, and that the battery may be loaded into the battery compartment 42 or unloaded from the battery compartment 42 in a second direction, which is different from the first direction. Therefore, the battery 43 can be installed in the preset position of the chassis 10 after at least two direction changes by taking the battery compartment 42 as the carrier of the battery 43, or the battery 43 is taken out from the preset position of the chassis 10, so that the chassis 10 can reasonably layout the installation position of the battery 43 according to the actual structure, and finally the chassis 10, the supporting device 100 and even the whole rehabilitation training device have more compact structure and less occupied space.

It will be further appreciated that, since the battery 43 is removably disposed on the chassis 10, the battery 43 can be replaced by the above-described battery replacement method when the battery assembly 40 is depleted. On the other hand, the manner of replacing the different batteries 43 can avoid the same battery 43 from being charged and discharged, and further, the service life of the battery 43 is reduced, the safety factor is reduced, and the like. On the other hand, if the battery 43 needs to be charged for reuse, the manner of replacing the different battery 43 can also avoid the need to wait for the battery 43 to be charged and occupy a longer rehabilitation training time.

The battery assembly 40 according to the embodiment of the present application will be described in further detail with reference to the accompanying drawings.

As shown in fig. 5, to facilitate taking the battery 43, the battery 43 may be provided with a grip structure 432. The holding structure 432 may be a handle including a protrusion with respect to the battery 43, and when the battery 43 is placed in the battery compartment 42, the handle may be disposed through the first opening 422 and partially outside the battery compartment 42, so as to facilitate the user to take out the battery 43. Of course, the holding structure 432 may be other structures that are convenient for the user to hold, which is not limited in this embodiment of the present application, for example, the holding structure 432 may be a flexible belt disposed on the battery 43. When the battery 43 is placed in the battery compartment 42, a portion of the flexible belt body passes through the first opening 422 and is located outside the battery compartment 42, so that a user can conveniently take out the battery 43.

In an embodiment of the present application, as shown in fig. 6, the battery 43 may have a first surface 433, a second surface 434, and a third surface 435 connected in sequence. The first surface 433 and the third surface 435 are disposed opposite. A gripping structure 432 is provided on the first surface 433 for a user to lift the cell 43. A second power connector 431 is disposed on the second surface 434 and/or the third surface 435.

In the first implementation of the second power connector 431 of the battery 43 provided in the embodiment of the present application: the side walls of the battery compartment 42 forming the first cavity 421 may include a first side wall 423 remote from the chassis 10 in a first direction. I.e. the first side wall 423 is horizontally displaced from the chassis 10. The second surface 434 is located on a side of the battery 43 remote from the first sidewall 423. Therefore, when the battery compartment 42 and the battery 43 are pushed in the first direction, the second power connector 431 of the battery 43 may be directly plugged into the first power connector 41 to achieve connection, or the second power connector 431 of the battery 43 may be directly separated from the first power connector 41.

In some embodiments, the second power connector 431 is convex with respect to the second surface 434, and when the battery compartment 42 is in the second position, a clearance space for movement of the second power connector 431 in the second direction may be reserved in the first cavity 421 of the battery compartment 42 in order to enable the second power connector 431 to also pass through the first opening 422 in the second direction to fit into the battery compartment 42.

Alternatively, as shown in fig. 6, the second surface 434 may be provided with a first recess 436, and the second power connector 431 is disposed within the first recess 436. Further, the second power connector 431 may be fixedly connected to a sidewall forming the first recess 436. Accordingly, as shown in fig. 7, the side wall of the battery compartment 42 forming the first cavity 421 is provided with a third opening 424 corresponding to the first recess 436. The third opening 424 may be in communication with the first opening 422. Alternatively, the third opening 424 may be two openings independent from the first opening 422. When the battery compartment 42 is located at the first position, the first power connector 41 is disposed through the third opening 424 and connected to the second power connector 431.

It will be appreciated that, in the case where the second power connector 431 is disposed in the first recess 436, there is no need to reserve a space for the second power connector 431 to move in the second direction in the battery compartment 42, compared to the case where the second power connector 431 protrudes outwardly relative to the second surface 434, so that the space occupied by the battery compartment 42 can be saved, or the battery 43 with a larger capacity can be disposed in the limited space of the first cavity 421 of the battery compartment 42.

In a second implementation of the second power connection 431 of the battery 43 provided in the examples of the present application: a second power connection 431 may be provided on the third surface 435. In use, the third surface 435 is the side of the battery 43 facing the support surface. The outer wall of the battery compartment 42 forming the first cavity 421 may be formed with a second opening towards the support surface. When the battery compartment 42 is located at the second position, after the user holds the holding structure 432 to place the battery 43 in the battery compartment 42 from top to bottom along the second direction, if the second power connector 431 is protruded with respect to the third surface 435, the second power connector 431 may be disposed through the second opening. Next, when the user pushes the battery compartment 42 and the battery 43 into the bottom of the chassis 10 in the first direction to the first position in synchronization, the first power connector 41 is connected to the second power connector 431 located outside the battery compartment 42.

Alternatively, the second power connector 431 may also be countersunk into the third surface 435. For example, the third surface 435 may also be provided with a first recess 436, and when the battery compartment 42 is moved to the first position, a second drive mechanism on the chassis 10 may drive the first power connector 41 through the second opening such that the first power connector 41 is connected to the second power connector 431.

Of course, the battery 43 may also have a second power connector 431 on both the second surface 434 and the third surface 435. Accordingly, a plurality of first power connectors 41 may be disposed on the chassis 10, and the plurality of first power connectors 41 and the plurality of second power connectors 431 are matched one by one. Alternatively, the plurality of first power connectors 41 may be connected to the same second power connector 431, or one first power connector 41 may be connected to the plurality of second power connectors 431, or one of the plurality of first power connectors 41 may be matched to one second power connector 431 on the battery 43, which is not limited in the embodiment of the present application. Thus, the battery 43 may power the rehabilitation training device as a whole through multiple channels, or the battery 43 may power different electrical components of the rehabilitation training device through multiple channels.

It is to be understood that the connection manner of the first power connector 41 and the second power connector 431 is not limited in the embodiment of the present application. For example, the first power connector 41 may be directly connected to the second power connector 431 by plugging and magnetically attracting. Alternatively, the second power connector 431 may be indirectly connected to the first power connector 41 through a functional circuit module such as a boost circuit, a current stabilizing circuit, etc. in the battery compartment 42, or a common circuit.

It is further understood that the manner in which the first power connector 41 supplies power to the rehabilitation training device is not limited in this embodiment. For example, the first power connector 41 may be directly contacted with and connected to a power line on the rehabilitation training device, or the first power connector 41 may indirectly supply power to the rehabilitation training device through other functional circuit modules or a common circuit.

Alternatively, as shown in fig. 5, the battery 43 may include an indicator feature 437. The indication structure 437 provided on the battery 43 can facilitate the user to view information of the battery 43, etc., and the specific structure of the indication structure 437 is not limited in this application.

For example, as shown in fig. 6, the indicator structure 437 may include an indicator light 4371. The indicator light 4371 is used to display the status of the battery 43. For example, the indication lamps 4371 may be provided in plurality, and the remaining power of the battery 43 may be displayed by lighting the indication lamps 4371 of different numbers and/or colors. Of course, the indicator 4371 may at least display the battery loss, the service life, whether the battery 43 is in a normal working state, and the like, which is not limited in the embodiment of the present application.

The indicator light 4371 is offset from the chassis 10 in the first direction. Thus, when the battery compartment 42 is in the first position and the second position, neither the chassis 10 obscures the indicator light 4371. Therefore, the user can directly observe the indicator 4371 to know the state of the battery 43 when the battery 43 is powered. Of course, in order to make it more convenient for the user to observe the indicator light 4371, the indicator light 4371 may be provided on the first surface 433 so that the user can clearly observe the indicator light 4371 with his/her head down.

For example, as shown in fig. 6, the indication structure 437 may include an indication flag 4372. For example, the indication mark 4372 may be a mounting direction mark provided on the surface of the battery 43. The user can know the assembly and disassembly modes of the batteries 43 in the battery assembly 40 through the indication marks 4372.

Alternatively, the first surface 433 of the battery 43 may abut against the chassis 10 when the battery compartment 42 is in the first position. Further, embodiments of the present application may limit movement of the battery assembly 40 through the chassis 10 so that the battery 43 may be more stably disposed within the battery compartment 42. Finally, the first power connector 41 and the second power connector 431 of the embodiment of the present application may be more firmly connected during the operation of the battery 43.

As shown in fig. 6, battery 43 may also include a third power connector 438, third power connector 438 being capable of charging battery 43 and/or powering the rehabilitation training device.

The third power connector 438 is offset from the chassis 10 in the first direction. Thus, when the battery compartment 42 is in both the first and second positions, the chassis 10 does not block the third power connector 438. So that a user can directly connect an external power source to the third power connector 438 without moving the battery compartment 42 and removing the battery 43.

Of course, in order to allow a user to more conveniently connect an external power source to the third power connector 438, the third power connector 438 may be provided on the first surface 433.

In the present embodiment, the battery 43 may further include an energy storage module capable of storing and outputting electric energy.

The third power connector 438, the energy storage module, and the second power connector 431 may be sequentially connected in series to form a path. Therefore, when the energy storage module needs to be charged, the third power connector 438 is connected to the external power supply, and the energy storage module is disconnected from the second power connector 431. At this time, the external power source only charges the energy storage module through the third power connector 438, and the energy storage module does not supply power to the rehabilitation training device through the second power connector 431, so as to avoid the battery 43 from being charged and discharged, and further improve the service life of the energy storage module.

The third power connector 438 may also be directly connected in series with the second power connector 431 to form another path. Therefore, during the process of charging the energy storage module, the third power connector 438 is connected to the external power, the third power connector 438 is connected to the second power connector 431, and the energy storage module is disconnected from the second power connector 431. At this time, the third power connector 438 may supply power to the rehabilitation training device through the second power connector 431, and the third power connector 438 may charge the energy storage module through another path. It is understood that the energy storage module only supplies power and does not supply power, so that the service life of the energy storage module can be prolonged. On the other hand, the charging of the energy storage module does not affect the third power connection 438 to power the rehabilitation training device through the second power connection 431.

The battery 43 and/or the battery compartment 42 may be provided with a guiding structure. The guiding structure can comprise a guide post and a guide sleeve which are matched with each other, a guide rail pair which is matched with each other, and the like. It is understood that the specific structure of the guiding structure is not limited in the embodiment of the present application, and the technical solution that the battery 43 can be inserted into the battery compartment 42 after passing through the first opening 422 along the preset direction is within the scope of protection of the present application.

As illustrated in fig. 5 and 6, the guide structure may include a first fool-proof portion 441 provided on the battery 43 and a second fool-proof portion 442 provided on a side wall of the battery compartment 42 forming the first cavity 421. The first fool-proof portion 441 may be formed by asymmetrically disposing opposite ends of the battery 43. For example, it is possible that the batteries 43 are asymmetrically arranged along both ends in a direction parallel to the support surface to form the first fool-proof portion 441. It will be appreciated that by providing the first fool-proof portion 441, the battery 43 can be prevented from being mounted erroneously when the battery 43 is mounted in the battery compartment 42, and further, the battery 43 and other parts are interfered to be damaged during the process of pushing the battery compartment 42 to the first position.

For example, as shown in fig. 5, the guide structure may include a guide slope 443. For example, the side walls forming the battery compartment 42 include guide ramps 443. The guide slope 443 is inclined toward the center of the first chamber 421 in a direction approaching the bottom surface of the battery compartment 42. Thus, the first opening 422 is made to gradually decrease in cross section in a direction approaching the first chamber 421. During the process of loading the battery 43 into the battery compartment 42, the battery 43 can slide along the guiding inclined plane 443 to realize centering, and finally, the battery 43 passes through the first opening 422 along the preset direction and is placed in the correct position of the battery compartment 42.

Referring to fig. 7 and 8, the battery compartment 42 is slidably coupled to the chassis 10. In the embodiment of the present application, the sliding connection may be directly formed between the battery compartment 42 and the chassis 10, or may be indirectly formed, and the manner of sliding connection between the battery compartment 42 and the chassis 10 is not limited in the embodiment of the present application.

Illustratively, as shown in fig. 8, fig. 7 is an assembled schematic view of the battery compartment and the chassis of the supporting device shown in fig. 2, and fig. 8 is a sectional view of the assembled schematic view of the battery compartment and the chassis of the supporting device shown in fig. 7 along the direction P-P. The battery assembly 40 may include a mounting member 45, and the mounting member 45 is fixedly coupled to the chassis 10. The mounting member 45 has mounted thereon a first guide rail 47 arranged in a first direction. A first slider 48 is slidably mounted on the first guide rail 47, and the first slider 48 is fixedly connected with the battery compartment 42. Thus, an indirect sliding connection is achieved between the chassis 10 and the battery compartment 42 via the mounting member 45, the first rail 47 and the first slider 48. Of course, in the embodiment of the present application, the mounting member 45 may be fixedly connected to the battery compartment 42, and the mounting member 45 may be slidably connected to the chassis 10, which is not limited in the embodiment of the present application.

Next, taking the supporting surface as the ground, the first direction as the horizontal direction, and the second direction as the vertical direction as an example, the working principle of the battery assembly 40 provided in the embodiment of the present application will be further explained.

When the chassis 10 is generally low relative to the ground, and the first power connector 41 is hidden between the chassis 10 and the ground, it is difficult for a medical staff or the like to observe and determine the specific position of the first power connector 41. Therefore, it is also difficult for the user to accurately push the battery 43 into the correct position between the chassis 10 and the support surface to connect the first power connector 41 and the second power connector 431.

As shown in fig. 5, the first opening 422 of the battery compartment 42 is disposed on a side of the battery compartment 42 facing away from the ground, so that a user can put the battery 43 into the battery compartment 42 connected to the chassis 10 from top to bottom along the second direction, and push the battery compartment 42 into the space between the chassis 10 and the ground along the horizontal direction to complete the installation. On the one hand, for the battery 43 with a part of heavy weight, the battery 43 is put into the battery compartment 42 from top to bottom in a light and labor-saving manner. On the other hand, the battery assembly 40 in the embodiment of the present application can be used as a carrier for the transfer motion in the installation process of the battery 43, so that the battery 43 can be conveniently connected with the first power connector 41 which is concealed on the chassis 10.

In order to enable the battery compartment 42 to slide in a preset direction relative to the chassis 10, the battery compartment 42 is prevented from being separated from the chassis 10, or the battery compartment 42 is prevented from interfering with other parts of the rehabilitation training device due to wrong travel during the sliding process. In embodiments of the present application, the battery assembly 40 may further include a limiting structure 46, and the limiting structure 46 may be directly or indirectly disposed on the battery compartment 42 and/or the chassis 10 to limit the travel of the relative sliding movement of the battery compartment 42 and the chassis 10.

As illustrated in fig. 8, the limiting structure 46 may include first limiting portions 461 disposed at both ends of the first rail 47 in the first direction, and thus indirectly disposed on the chassis 10. When the battery compartment 42 slides to the first position, the first slider 48 abuts against one of the first limiting portions 461 to limit the continued movement of the battery compartment 42 in the first direction toward the chassis 10. When the battery compartment 42 slides to the second position, the first slider 48 abuts against the other first stopper 461 to restrict the battery compartment 42 from continuing to move in the first direction away from the chassis 10.

For example, the limit structure 46 may include a second limit feature 462 formed on the battery compartment 42. When the battery compartment 42 slides to the first position, the first guide rail 47 abuts against the second stopper 462 to restrict the battery compartment 42 from continuing to move in the first direction toward the chassis 10.

Alternatively, as shown in fig. 4, to provide for the efficiency of assembly of the rehabilitation training device. A quick-positioning structure 111 may be provided on the chassis 10 that mates with the mount 45. Illustratively, the chassis 10 may include a plurality of rails 11. The quick positioning structure 111 may be a positioning boss, a positioning counter, a positioning groove, etc. provided on the cross bar 11. Therefore, in the assembly process, the mounting piece 45 can be placed at the quick positioning structure 111 to realize quick positioning of the mounting piece 45 and the underframe 10, and then the mounting piece 45 and the underframe 10 are locked and fixed in a threaded manner.

In the embodiment of the present application, as shown in fig. 4, the first power connector 41 may be fixedly connected to the mounting member 45, so that the first power connector 41 may be indirectly disposed in the battery compartment 42. The mounting member 45 is fixedly connected to the chassis 10 and slidably connected to the battery compartment 42. Thus, as the battery compartment 42 moves relative to the chassis 10, the battery compartment 42 also moves relative to the first power connector 41.

To prevent relative movement of the battery compartment 42 and the chassis 10 during operation of the rehabilitation training device, as shown in fig. 2, from causing the first power connector 41 and the second power connector 431 to separate, the battery assembly 40 may further include a locking mechanism 49, the locking mechanism 49 locking the battery compartment 42 to the first position.

Illustratively, the locking mechanism 49 includes a cover 491 and a catch 492. One end of the cover 491 is rotatably connected to the mounting member 45 for indirect rotational mounting to the chassis 10. The catch 492 is at least partially disposed on the battery compartment 42. When the battery compartment 42 is moved to the first position, the other end of the cover 491 can be rotated to the position of the battery compartment 42 and locked and fixed with the lock catch 492, so that the battery compartment 42 is locked and fixed with the chassis 10.

Alternatively, as shown in fig. 2, the locking mechanism 49 may also lock the battery 43 with the battery compartment 42 when the locking mechanism 49 locks the battery compartment 42 to the first position.

Illustratively, the cover 491 at least partially covers the first opening 422 of the battery compartment 42. Thus, embodiments of the present application may at least partially close the first opening 422 by the cover 491 to limit the battery 43 from exiting the battery compartment 42. It can be seen that in the embodiment of the present application, the user can simultaneously complete the two actions of locking the battery compartment 42 with the chassis 10 and locking the battery compartment 42 with the battery 43 by operating the cover plate 491, thereby simplifying the locking action of the battery assembly 40 as a whole.

Alternatively, as shown in fig. 4, the catch 492 may include a first locking element 4921 and a second locking element 4922. The first locking member 4921 is provided on the battery compartment 42 and the second locking member 4922 is provided on the cover 491. The second locking member 4922 may be locked with the first locking member 4921. For example, the first locking member 4921 is a protrusion formed on the cover 491, and the second locking member 4922 is a link assembly that can be snapped onto the protrusion.

It should be understood that the specific structure of the locking mechanism 49 is not limited in this embodiment, as long as the structure capable of locking the battery compartment 42 and the chassis 10 is within the scope of the embodiment of this application, for example, the locking mechanism 49 may further include a magnetic component, a snap connection component, and the like.

Alternatively, as shown in fig. 2, the chassis 10 may include two crossbars 11. The two crossbars 11 may be arranged substantially in parallel. The ends of the two crossbars 11 on the same side are connected by a carrier 12.

In the present embodiment, at least one battery assembly 40 may be provided on each rail 11. Illustratively, one battery assembly 40 is provided on each crossbar 11, with two battery assemblies 40 being disposed opposite each other. Alternatively, two or three battery packs 40 may be provided on each of the two crossbars 11, which is not limited in the embodiment of the present application.

It will be appreciated that when a plurality of battery packs 40 are provided on the chassis 10, one of the batteries 43 may be used as a main battery 43 to supply power to the rehabilitation training device, the other battery 43 may be used as a sub-battery 43 to be standby or be charged after being taken out, or both batteries 43 may be used to supply power to the rehabilitation training device at the same time, which is not limited in the embodiment of the present application.

In the embodiment of the present application, the battery 43 of each battery assembly 40 may further be connected with a detection module, where the detection module is used to detect whether the current output of the battery 43 is normal. All detection modules are connected with a second control module.

The second control module is configured to: when one of the detection modules detects that the current output of the corresponding battery 43 is abnormal, the control module can cut off the circuit output of the battery 43 and switch to the other battery 43 to supply power for the rehabilitation training device.

It can be seen that the plurality of battery assemblies 40 provided on the chassis 10 not only reduces the limit of the battery capacity of the battery 43 on the use of the rehabilitation training device, but also reduces the risk of the battery 43 failure to the rehabilitation training device.

It will be appreciated that by providing a plurality of battery packs 40 on the chassis 10, a user may also charge several or all of the battery packs 40 at the same time according to the actual situation, so that the charging speed of the battery packs is increased by one to several times without changing the sum of the battery capacities. Of course, the center of gravity of the whole supporting device 100 can be adjusted by reasonably distributing a plurality of battery assemblies 40. In addition, in the case of inconvenient battery accommodation, the weight of the battery assembly 40 may be reduced to facilitate the user to take out the discharge cell 43.

Alternatively, as shown in fig. 2, each cross bar 11 is provided with a roller 13, wherein at least one cross bar 11 is provided with two rollers 13. And then the chassis 10 is placed on the supporting surface through the rollers 13 which are not arranged in a collinear manner, so that the chassis 10 can synchronously advance with a wearer in the forward process of wearing the rehabilitation training device by the wearer, and further the real-time support of the chassis 10 on the wearer in the rehabilitation training process is realized.

Wherein, a power source may be connected to a portion of the roller 13 so as to drive the supporting device 100 as an auxiliary power and the wearer to travel during the wearer's travel.

Wherein, a steering mechanism 14 may be connected to a part of the rollers 13, so that the supporting device 100 is driven to steer by the steering mechanism 14 during the running process of the wearer, so as to assist the wearer to complete the steering action.

It will be appreciated that as shown in fig. 1, the first adjustment assembly 30 is coupled to the chassis 10. The first adjusting component 30 may be a sliding table cylinder, a linear motor, a gear rack transmission mechanism, etc., and the specific structure of the first adjusting component 30 is not limited in this embodiment.

Alternatively, the support assembly 20 may be disposed above the chassis 10. The support assembly 20 may be a handrail that is coupled to the first adjustment assembly 30. Thus, the first adjustment assembly 30 can adjust the armrest to a predetermined position so that the wearer can more comfortably hold the armrest. Of course, the sensor can be arranged at the supporting part of the wearer on the armrest, and when the hands of the user contact the sensor, the body data such as heart rate of the wearer can be collected through the sensor, so that the rehabilitation training device can provide more proper rehabilitation training according to the body state of the wearer.

Of course, the support device 100 may further include a post provided on the base frame 10, with the support assembly 20 or the first adjustment assembly 30 being connected to the post, and indirectly connected to the base frame 10 through the post. In the present embodiment, the supporting component 20 or the first adjusting component 30 is indirectly connected to the chassis 10 through the upright, and also belongs to the case that the supporting component 20 or the first adjusting component 30 is connected to the chassis 10.

Alternatively, as shown in fig. 1, the support assembly 20 may include a first connection member 21, a second adjustment structure 22, and a second connection member 23.

The first connecting part 21 is illustratively connected to the first adjusting assembly 30, so that the height of the first connecting part in the second direction, i.e. perpendicular to the supporting surface, can be adjusted by the first adjusting assembly 30. The first connection part 21 is connected to the first adjustment assembly 30 by the second adjustment structure 22. Thus, the position of the second connection member 23 in the direction parallel to the support surface can be adjusted by the second adjustment structure 22. Further, when the second connection member 23 is connected with the auxiliary training device 500, the position of the second connection member 23 can be adjusted from a plurality of directions by the cooperation of the first adjustment assembly 30 and the second adjustment structure 22, so that the second connection member 23 can support the auxiliary training device 500 at a proper position to provide a supporting force for the user.

It will be appreciated that in order to allow the natural movement of the body of the wearer during rehabilitation training, the auxiliary training device 500 may be moved relative to the support device 100 following the change in posture of the patient's body, and the auxiliary training device 500 may be configured to be movable within a preset range relative to the support device 100 when the second connection member 23 is adjusted to the set position. For example, the first connecting member 21 and/or the second connecting member 23 may be locally elastically deformed, so that the auxiliary training device 500 and the supporting device 100 can relatively move within a preset range through the elastic deformation of the second connecting member 23, and of course, the second connecting member 23 may also be connected to the auxiliary training device 500 through a universal joint or the like, which is not limited in the embodiment of the present application.

For example, as shown in fig. 1, auxiliary training device 500 may include a lower limb activity assembly 51 and a torso immobilization assembly 52. The lower limb movement assembly 51 can assist the lower limb of the wearer in lower limb gait rehabilitation training. Torso securing assembly 52 is capable of being worn about the torso of a wearer. At this point, support device 100 may be coupled to lower limb activity assembly 51 and/or torso fixation assembly 52, thereby providing support for a wearer wearing exoskeleton apparatus by support device 100.
