The lower limb rehabilitation exerciser is used for assisting a patient to carry out walking training, the armrest mechanism which can be held by the patient in the exerciser is mainly improved, other structures of the lower limb rehabilitation exerciser can be realized based on the prior art, and the lower limb rehabilitation exerciser is not detailed here.

Referring to fig. 1 and 2, fig. 1 and 2 are schematic structural views illustrating an armrest mechanism of a lower limb rehabilitation exercise device in a use state and a non-use unfolded state, respectively.

In this embodiment, the armrest mechanism includes a support base 10 and two armrest assemblies, both of which are mounted on the support base 10, and are referred to herein as a left armrest assembly 20a and a right armrest assembly 20b, respectively, for convenience of description and understanding.

Wherein "left" and "right" are defined as left and right sides with respect to left and right hand sides of a patient in normal use on the lower limb rehabilitation exercise machine, as can be understood from fig. 1, the support base 10 is located at the back in normal use of the patient, the side of the support base 10 is referred to as the back, the side of the armrest assembly away from the support base 10 is referred to as the front, and the upper and lower are referred to as the upper and lower in the vertical direction.

In this embodiment, the left armrest assembly 20a and the right armrest assembly 20b have the same composition and are structurally symmetrical with respect to the vertical centerline of the support base 10.

The structure of the one-sided armrest assembly is described below in conjunction with the right armrest assembly 20b shown in fig. 3 and 4, with the structure of the left armrest assembly 20a being understood by reference, and the same reference numerals are used in the figures.

The right armrest assembly 20b includes a support portion 21 and an armrest portion 22, a rear end of the support portion 21 is connected to the support base 10, a rear end of the armrest portion 22 is rotatably connected to a front end of the support portion 21, a rotation center line of the armrest portion is parallel to a vertical direction, such that when the armrest portion 22 rotates around a rotation center of the rear end thereof, the front end thereof can rotate outwardly or inwardly, and a direction away from a center of the support base 10 is defined as outwardly, and correspondingly, a direction close to the center of the support base 10 is defined as inwardly, that is, the armrest portion 22 of the left armrest assembly 20a rotates inwardly toward the side close to the right armrest assembly 20b and rotates outwardly toward the side away from the right armrest assembly 20b, and the armrest portion 22 of the right armrest assembly 20b rotates inwardly toward the side close to the left armrest assembly 20a and rotates outwardly toward the side away from the left armrest assembly 20 a.

Wherein a locking structure is further provided between the support portion 21 and the armrest portion 22 for limiting the relative position between the armrest portion 22 and the support portion 21 in the use condition. The use state refers to a state in which the patient can hold the armrest assembly on the lower limb rehabilitation exercise machine for walking training, and at this time, the armrest portion 22 is in a proper position in the left-right direction with respect to the support portion 21 for the convenience of the patient, and the proper position is set differently according to different training purposes, etc.

As shown in fig. 1, it can be understood that the two armrest assemblies and the support base 10 form a U-shaped structure with a forward opening, and a patient needs to get on or off the device through the opening between the two armrest assemblies, generally speaking, when the left armrest assembly 20a and the right armrest assembly 20b are in use, the two armrest portions 22 are closer in the left-right direction, which is convenient for the patient to hold, but not beneficial for the patient to get on or off the device, after the above armrest assembly is adopted, the armrest portions 22 on both sides can rotate outwards relative to the support portion 21, so as to enlarge the distance between the two armrest portions 22, i.e. increase the opening between the upper and lower devices, as shown in fig. 2, which is convenient for the patient to get on or off the device.

After the patient gets on the equipment, the armrest parts 22 on the two sides are rotated inwards to return to the use state and are locked through the locking structure, so that the armrest parts 22 cannot sway left and right when the patient uses the equipment, the use safety and reliability are ensured, the patient can release the locking of the locking structure after training, the armrest parts 22 are rotated outwards when the patient needs to get off the equipment, and the armrest parts 22 are rotated inwards to the use state and locked after the patient gets off the equipment, so that the armrest parts 22 are prevented from rotating randomly.

In general, the two support portions 21 of the left armrest assembly 20a and the right armrest assembly 20b are disposed in parallel, and each extend in the front-rear direction.

As shown in fig. 3 and 4, in the present solution, the armrest portion 22 of the right armrest assembly 20b includes a holding section 223 far away from the supporting portion 21, and with reference to fig. 1, in the use state, the holding section 223 is inclined upward and inward, and the structure of the armrest portion 22 of the left armrest assembly 20a is consistent with this, so that when a patient faces the holding section 223 on the device, the two holding sections 223 are substantially in a shape of a Chinese character 'ba' in the use state, and are coordinated with the holding direction of the human body, so that the patient has a good experience of holding for a long time, and at the same time, the holding section 223 is designed to be inclined upward, so that the armrest assembly can adapt to patients with different heights within a certain range.

Specifically, the armrest portion 22 further includes a first support means 221 and a second support means 222, the first support means 221, the second support means 222 and the holding section 223 are sequentially connected, the first support means 221 is of a straight line structure and extends in the front-rear direction, the second support means 222 is of a curved structure, and the holding section 223 is in the above-mentioned upward and inward inclined state in the use state due to the curved design of the second support means 222.
