[0028] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0029] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0030] Please refer to Figure 1-7 The shoe-wearing assisting device provided in the embodiment of the present application comprises a storage box 1, a carrying plate 2, a shoe horn 3 and a driving mechanism 4. The carrying plate 2 is used to place shoes, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0031] The storage box 1 has a containing space 1A, and a supporting rod 1B is provided on the storage box 1 .

[0032] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the storage box 1 is roughly in a rectangular parallelepiped structure, with its height direction being the first direction X, its length direction being the second direction Y, and its width direction being the third direction Z.

[0033] The storage box 1 includes two side panels 11 arranged in parallel and spaced apart along a third direction Z, a baffle 12 arranged in parallel and spaced apart along a second direction Y and connecting the two side panels 11, and a bottom panel 13 connected to the side panels 11 and the baffle 12.

[0034] The carrying plate 2 is suspended in the storage box 1 and is parallel to and spaced from the bottom plate 13 . Two opposite sides of the carrying plate 2 along the third direction Z are respectively provided with avoidance openings 2A.

[0035] The shoe horn 3 comprises a shoe horn body 31 suspended on the carrier plate 2 along a first direction X, a driving rod 32 spaced from the carrier plate 2 along a second direction Y, a lifting rod 33 connecting the driving rod 32 and the shoe horn body 31, a transmission member 34 fixed on the storage box 1, and a rack 35 fixed on the carrier plate 2. The transmission member 34 comprises a turntable portion 341 rotatably connected to the driving rod 32, and a gear 343 disposed between the turntable portion 341 and the storage box 1 and meshed with the rack 35 to drive the turntable portion 341 to rotate, wherein the support rod 1B slidably passes through the lifting rod 33 along the first direction X, the driving rod 32 is rotatably connected to the lifting rod 33, and the connection between the turntable portion 341 and the driving rod 32 is spaced from the axis of the turntable portion 341.

[0036] The shape of the shoe horn body 31 matches the shape of the user's heel and the shoe heel, thereby making it easier for the user to put on shoes when using the shoe-wearing auxiliary device without damaging the shoe heel or causing harm to the user's heel.

[0037] The driving mechanism 4 is arranged in the storage box 1. Figure 4 and Figure 6 As shown, two drive mechanisms 4 are provided at intervals along the second direction Y. It is understandable that in other embodiments, three, four, etc. drive mechanisms 4 may also be provided at intervals along the second direction Y.

[0038] The driving mechanism 4 includes a spring 41, a fixed seat 42 fixed in the storage box 1, and a guide column 43 that can move through the fixed seat 42 along the first direction X, a clamping member 44 and a fork 45 that pass through the avoidance opening 2A along the first direction X and are spaced from the guide column 43. The guide column 43 is connected to the supporting plate 2, the spring 41 is sleeved on the guide column 43 and is located between the fixed seat 42 and the supporting plate 2, and the fixed seat 42 or / and the supporting plate 2 abut against the spring 41, the clamping member 44 has a connecting pin 44A, and the end of the guide column 43 away from the supporting plate 2 has a latch 431, the fork 45 has a first slide groove 45A for inserting the connecting pin 44A and a second slide groove 45B for inserting the latch 431, the fork 45 can rotate around an axis, and when the fork 45 rotates, the connecting pin 44A and the latch 431 can slide relative to the first slide groove 45A and the second slide groove 45B respectively to drive the clamping member 44 to move along the third direction Z.

[0039] The shoe-wearing assistive device implements shoe-wearing through the following steps:

[0040] The shoe is placed on the supporting plate 2, and an external force is applied to the supporting plate 2 by the sole of the foot to drive the supporting plate 2 to move along the first direction to a position close to the bottom plate 13. At this time, the supporting plate 2 will sequentially drive the shoe horn body 31 to move upward and compress the spring 41 to make it produce elastic deformation. In this process, the external force applied by the sole of the foot also makes the shoe move backward so that the shoe horn body 31 is suspended above the heel.

[0041] The sole of the foot removes the external force exerted on the supporting plate 2, and the supporting plate 2 moves to the initial position under the elastic force of the spring 41. At this time, the supporting plate 2 drives the shoe horn body 31 to move downward through the rack 35, the transmission member 34, the driving rod 32 and the lifting rod 33 in sequence, so that the shoe horn body 31 is inserted into the shoe and contacts the heel thereof;

[0042] The foot wears into the shoe and applies an external force to the supporting plate 2 through the foot to drive the supporting plate 2 to move along the first direction to a position close to the bottom plate 13. At this time, the supporting plate 2 drives the shoe horn 31 to move upward through the rack 35, the transmission member 34, the driving rod 32 and the lifting rod 33 in sequence so that the shoe horn 31 is pulled out of the shoe to complete the shoe wearing, and the spring 41 is compressed to generate elastic deformation;

[0043] The leg is lifted to separate the shoe and the foot from the supporting plate 2. As the supporting plate 2 loses the external force, the supporting plate 2 moves to the initial position under the elastic force of the spring 41. At this time, the supporting plate 2 drives the shoe horn body 31 to move downward to the initial position through the rack 35, the transmission member 34, the driving rod 32 and the lifting rod 33 in sequence.

[0044] Among them, in the above process, the stability of the movement of the supporting plate 2 can be improved (that is, it can be kept parallel to the base plate 13) by the guiding effect produced by the cooperation of the guide column 43 and the fixing seat 42, thereby reducing the demand for the stability of the movement of the supporting plate 2 by only elastically supporting the supporting plate 2 by the spring 41; at the same time, when the supporting plate 2 moves along the first direction to a position close to the base plate 13, the supporting plate 2 can also drive the clamping member 44 through the guide column 43 and the fork 45 (at this time, the fork 45 rotates, and the connecting pin 44A and the latch pin 431 slide relative to the first slide groove 45A and the second slide groove 45B respectively) to clamp the shoe so that the shoe can be fixed when the foot is wearing the shoe, and when the supporting plate 2 moves along the first direction to a position away from the base plate 13, the clamping member 44 can be driven by the guide column 43 and the fork 45 to release the clamped shoe.

[0045] like Figure 6As shown, a fixing body 21 is fixed on the carrier plate 2, a guide column 43 is connected to the fixing body 21 via a pin 23, and a spring 41 only abuts against a fixing seat 42. In other words, the guide column 43 and the carrier plate 2 are indirectly connected via the pin 23 and the fixing body 21. It is understood that the connection method between the guide column 43 and the carrier plate 2 is not limited thereto, for example, in other embodiments, the guide column 43 and the carrier plate 2 may also be directly connected.

[0046] The shift fork 45 includes a rotating portion 451 and a first portion 453 and a second portion 455 extending from two opposite sides of the rotating portion 451. The first portion 453 is formed with a first slide groove 45A, and the second portion 455 is formed with a second slide groove 45B. One of the fixed seat 42 and the rotating portion 451 is provided with an axial hole 5, and the other is provided with a rotating shaft 6 inserted into the axial hole 5. The axis of the rotating shaft 6 is the rotating axis of the shift fork 45.

[0047] like Figure 3 and Figure 7 As shown, the shaft hole 5 is provided on the rotating portion 451, and the rotating shaft 6 is provided on the fixed seat 42. It can be understood that in other embodiments, the rotation connection between the rotating portion 451 and the fixed seat 42 can also be configured as follows: the rotating shaft 6 is provided on the rotating portion 451, and the shaft hole 5 is provided on the fixed seat 42. In other words, the fixed seat 42 and the rotating portion 451 are provided with the shaft hole 5 on one side, and the rotating shaft 6 inserted into the shaft hole 5 on the other side, and both can realize the rotation of the fork 45 around an axis.

[0048] like Figure 3 and Figure 7 As shown, the shift fork 45 is bent at the rotating portion 451. With such a configuration, when the connecting pin 44A slides relatively with the first slide slot 45A, the force applied by the first portion 453 to the clamping member 44 has a greater component in the third direction Z, thereby providing a greater clamping force.

[0049] like Figure 7 As shown, the fixing seat 42 extends along the third direction Z and is fixed on the side plate 11. A mounting hole 421 is penetrated through the fixing seat 42. The clamping member 44 includes a clamping portion 441 passing through the avoidance opening 2A and a fixing portion 443 connected to the clamping portion 441 and arranged on the fixing seat 42. The connecting pin 44A is arranged on the fixing portion 443. During installation, the first part 453 passes through the mounting hole 421 so that the connecting pin 44A is inserted into the first slide groove 45A.

[0050] like Figure 1 and Figure 2As shown, a mounting groove 423 extending along the third direction Z is formed on the fixing seat 42, the fixing portion 443 is placed in the mounting groove 423, and the mounting hole 421 penetrates the fixing seat 42 on the bottom wall of the mounting groove 423. In this way, the movement of the clamping member 44 can be limited to the third direction Z and prevented from moving in other directions.

[0051] The shoe-wearing assistive device further comprises a push-type switch spring lock buckle 7 and a lock tongue 8 that can be locked with the push-type switch spring lock buckle 7. Figure 6 As shown, the push-type switch spring lock buckle 7 is fixed on the fixing seat 42, and the lock tongue 8 is fixed on the carrier plate 2. It can be understood that in other embodiments, the push-type switch spring lock buckle 7 can also be set to be fixed on the carrier plate 2, and correspondingly, the lock tongue 8 is fixed on the fixing seat 42. In other words, one of the push-type switch spring lock buckle 7 and the lock tongue 8 is fixed on the fixing seat 42, and the other is fixed on the carrier plate 2. In this way, when the carrier plate 2 drops to a preset distance, the push-type switch spring lock buckle 7 and the lock tongue 8 are locked to fix the carrier plate 2 at the preset position, and when the carrier plate 2 needs to rise, the push-type switch spring lock buckle 7 and the lock tongue 8 can be disengaged by applying an external force to the carrier plate 2 again.

[0052] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
