[0020] Figure 4 This is a schematic diagram of the exploded structure of the supporting handrail in this utility model. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See Figures 1 to 4 As shown, a transfer cart support structure includes a frame 1. The bottom of the frame 1 is provided with a plurality of casters 2 for moving the transfer cart. The frame 1 includes a base frame 3 and a single lifting column 4 connected to the central axis of the base frame 3. The movable end of the lifting column 4 is connected to a support armrest 5, and a single-board seat cushion 6 is connected to the support armrest 5 and placed below it.

[0023] This moving vehicle uses a single lifting column 4 to support the support armrest 5 and seat 6, so that the frame 1 does not need to add a corresponding mounting frame structure, reducing the complexity of the frame 1 structure and making the frame 1 structure simpler.

[0024] In addition, the height of the armrest and seat 6 can be adjusted at the same time by using the lifting column 4, without having to operate the two parts separately, making it more convenient to use.

[0025] Furthermore, after the user sits down, the lifting column 4 is positioned between the two legs, while the outer side of the legs has more lateral movement space, which can improve the user's riding comfort and reduce the restriction on the legs.

[0026] In this embodiment, the left and right sides of the seat cushion 6 are provided with hanging connectors that are connected to the support armrest 5; the hanging connectors include a number of spaced flexible strips 7, and the seat cushion 6 is suspended below the support armrest 5 by the flexible strips 7.

[0027] When the support armrest 5 can be folded, the seat cushion 6 is connected to the support armrest 5 by a flexible strap 7, which can save space when folded. Moreover, the flexible connection between the seat cushion 6 and the support armrest 5 can also play a certain role in shock absorption and cushioning during the use of the transfer vehicle, which can improve the comfort of the user.

[0028] The length of the flexible strip 7 on each side gradually decreases as it moves away from the lifting column 4. The seat cushion 6 is inclinedly connected to the lower part of the support armrest 5 by flexible strips 7 of different lengths. When the user rides the transfer vehicle, the user will face the side of the lifting column 4. Therefore, the inclined seat cushion 6 can prevent the user's buttocks from sliding backward and play a role in the stability of the ride.

[0029] One end of the flexible band 7 is connected to the seat cushion 6, and the other end of the flexible band 7 is connected to a buckle 71. A lock 72 is hung on one side of the support armrest 5 corresponding to the buckle 71. Through the buckle 71 and the lock 72, the seat cushion 6 can be detachably installed on the support armrest 5. This structure allows the seat cushion 6 to be completely removed and placed under the user's buttocks.

[0030] The supporting armrest 5 has a "U" shaped structure, including a middle section 51 and two armrests 52. The middle section 51 is connected to the lifting column 4, and the two armrests 52 are symmetrically connected to both ends of the middle section 51 and extend laterally towards the front of the lifting column 4. The seat cushion 6 is connected to the armrests 52. The supporting armrest 5 has sufficient strength to support the user. The "U" shaped supporting armrest 5 is simple in overall design and occupies little space when folded. The armrests 52 can support the seat cushion while maintaining the function of an armrest.

[0031] The support armrest 5 has two handles 53 arranged on the left and right at the front and rear positions between the lifting column 4 and the seat cushion 6. The two handles 53 are mainly convenient for users. When users need to get up or lift their buttocks, they can hold the handles 53 to help them use their arms to support their body.

[0032] The rear side of the lifting column 4 is provided with a tube bracket 8, and the middle section 51 of the support handrail 5 is rotatably connected to the tube bracket 8; the front side of the lifting column 4 is fixedly provided with a support structure, and the handrail 52 rests on the upper side of the support structure when in use.

[0033] This structure allows the support armrest 5 to fold, so that it can be flipped backwards to the rear of the lifting column 4 when stored, which can reduce the lateral space occupied. When unfolded, the support structure can support the support armrest 5, so that the support armrest 5 remains in a lateral state relative to the lifting column 4.

[0034] In this embodiment, the support structure includes a support crossbar 9, with tube clamps 91 at both ends of the support crossbar 9 that elastically or with interference grip the handrail 52. A connecting block 92 connected to the lifting column 4 is fixed in the middle of the support crossbar 9. The connecting block 92 has an arc that fits the surface of the lifting column 4, making the connection more secure.

[0035] The two handles 53 mentioned above are fixed to the support crossbar 9 on the left and right sides, and the handles 53 are also covered with anti-slip grip sleeves 531, which also have an anti-slip effect.

[0036] The lifting column 4 includes a fixed column 41, a movable column 42, and a push rod body 43 with a motor. The fixed column 41 is vertically fixed on the frame 1. The movable column 42 is sleeved on the fixed column 41. The support armrest 5 is connected to the top of the movable column 42. The push rod body 43 is vertically arranged inside the movable column 42, and its telescopic push rod is connected to the bottom end of the fixed column 41.

[0037] The seat cushion 6 is made of a rigid board, and a defecation port 601 is provided in the middle of the board; the defecation port 601 allows the user to defecate while sitting on the transfer cart, reducing the user's transfer process and improving the convenience of the transfer cart.

[0038] The support armrest 5 is fitted with several elastic armrest gloves 54. The elastic armrest gloves 54 are mainly fitted on the support armrest 5 except for the connection positions of the tube clamp 8, the tube clamp 91, and the lock 72. The elastic armrest gloves 54 on the middle section 51 play an anti-slip role when the caregiver pushes the transfer cart, while the elastic armrest gloves 54 on the handrail 52 can insulate the cold metal material when the user's arm is placed on the support armrest 5, and the soft elastic armrest gloves 54 improve the comfort of the handrest.
