Specific embodiments

[0020] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0021] Embodiment:

[0022] Referring to Figures 1 to 4 , a folding vehicle capable of saving floor space disclosed by the present utility model includes two side plates 1. The center of the side plate 1 is provided with an opening. The left and right sides of the opening in the center of the side plate 1 form two fixed columns 2. The upper half of the outer surface of the fixed column 2 is fixedly sleeved with a fixed block 3. The lower half of the outer surface of the fixed column 2 is slidably sleeved with a slider 4. The side wall of the fixed block 3 is hinged with a connecting rod 5. One end of the connecting rod 5 far from the corresponding fixed block 3 is hinged with the corresponding slider 4. The middle parts of the corresponding two connecting rods 5 are rotatably connected by a pin shaft. A locking part 6 is arranged inside the side plate 1. The lower halves of the two side plates 1 are connected by a scissor extension mechanism 7.

[0023] In this embodiment, when the folding vehicle needs to be stored, the distance between the two side plates 1 decreases, the connecting rod 5 rotates, and drives the slider 4 to move downward. When the folding vehicle needs to be unfolded, the distance between the two side plates 1 increases, the connecting rod 5 rotates, and drives the slider 4 to move upward. Therefore, only by limiting the slider 4 after the folding vehicle is completely stored or unfolded, the extension or contraction deformation of the folding vehicle can be restricted.

[0024] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, the locking part 6 includes an upper cavity 61 opened on the upper half of the side plate 1. The bottom wall of the upper cavity 61 is provided with two vertical cavities 62. The two vertical cavities 62 are respectively located inside the corresponding two fixed columns 2. A moving plate 63 is arranged above the side plate 1. The bottom of the moving plate 63 is fixedly connected with a plurality of first rods 64. The first rods 64 slidably pass through the top wall of the side plate 1, and the bottom ends of the first rods 64 are fixedly connected with the sliding plate 65. A plurality of springs 66 are fixedly connected between the sliding plate 65 and the bottom wall of the upper cavity 61. A locking unit 67 is arranged inside the vertical cavity 62.

[0025] In this embodiment, the sliding plate 65 is slidably connected to the upper cavity 61. When it is necessary to adjust the state of the folding bike, press downward to move. The first rod 64 drives the sliding plate 65 to move downward, and the spring 66 is compressed.

[0026] In a further preferred embodiment of the present utility model, as Figure 4 shown, the locking unit 67 includes a second rod 671 fixedly connected to the bottom of the sliding plate 65. The bottom end of the second rod 671 is fixedly connected with a straight rack 672. The straight rack 672 is located in the corresponding vertical cavity 62. Two screw sleeves 673 are rotatably connected to the inner side wall of the vertical cavity 62. A gear 674 is fixedly connected to the outer peripheral surface of the screw sleeve 673. The gear 674 meshes with the straight rack 672. A screw rod 675 is threadedly connected to the screw sleeve 673. One end of the screw rod 675 located outside the screw sleeve 673 is fixedly connected with a clamping block 676. The clamping block 676 slides through the inner side wall of the vertical cavity 62 and partially extends outside the fixing column 2.

[0027] In this embodiment, when the spring 66 is in a natural state, the clamping block 676 partially extends outside the fixing column 2.

[0028] When the sliding plate 65 moves downward, the straight rack 672 is driven to move downward through the second rod 671. The straight rack 672 drives the gear 674 to rotate. The gear 674 drives the screw sleeve 673 to rotate. The screw sleeve 673 drives the screw rod 675 and the clamping block 676 to move horizontally. The part of the clamping block 676 located outside the fixing column 2 enters the fixing column 2. At this time, the slider 4 can slide, so the state of the folding bike can be adjusted.

[0029] Further, when the straight rack 672 moves downward and contacts the inner bottom wall of the vertical cavity 62, the clamping block 676 does not protrude from the fixing column 2 at all, and at this time, part of the clamping block 676 is still located inside the inner side wall of the vertical cavity 62 and does not completely enter the vertical cavity 62.

[0030] When the folding bike is in the unfolded state, the corresponding clamping block 676 is in contact with the bottom surface of the slider 4. When the folding bike is in the stored state, the corresponding clamping block 676 is in contact with the top surface of the slider 4.

[0031] In a further preferred embodiment of the present utility model, as Figure 3 shown, the side wall of the fixing column 2 is fixedly connected with an upper limit plate 8 and a lower limit plate 9 from top to bottom in sequence.

[0032] In this embodiment, the upper limit plate 8 and the lower limit plate 9 are used to limit the slider 4, helping the staff to clearly know whether the slider 4 has moved to the appropriate position. When the folding bike is fully unfolded, the slider 4 is in contact with the bottom surface of the upper limit plate 8. When the folding bike is fully stored, the slider 4 is in contact with the top surface of the lower limit plate 9.

[0033] In a further preferred embodiment of the present utility model, as Figure 1As shown, there is a storage cloth bag 10 with an open top between two side plates 1, and the upper half of the side wall of the storage cloth bag 10 is connected to the upper half of the side wall of the side plate 1.

[0034] In this embodiment, when there is no storage cloth bag 10, the device can only carry some large items, and directly placing large items on the scissor extension mechanism 7 will cause deformation of the scissor extension mechanism 7. After the storage cloth bag 10 is installed on the two side plates 1, it can store and transport some small-sized items without directly pressing on the scissor extension mechanism 7, improving the service life of the scissor extension mechanism 7.

[0035] The storage cloth bag 10 can be folded without hindering the extension and folding of the folding cart.

[0036] In a further preferred embodiment of the present utility model, as Figure 1 shown, the storage cloth bag 10 is adhesively bonded to the side plate 1 through Velcro.

[0037] In this embodiment, the viscosity of the Velcro should be relatively large to support the storage cloth bag 10 and the internal items, and prevent loosening between the storage cloth bag 10 and the side plate 1. The storage cloth bag 10 is connected to the side plate 1 through Velcro, which is convenient for replacing the storage cloth bag 10.

[0038] The implementation principle of the above embodiment is as follows:

[0039] When the folding cart is in the storage state and needs to be unfolded, the staff presses two moving plates 63 and pulls the two side plates 1 outwards at the same time. The moving plate 63 drives the block 676 to retract into the fixed column 2, and the slider 4 can move upwards. When the distance between the two side plates 1 reaches the maximum, that is, when the folding cart is fully unfolded, the slider 4 contacts the upper limit plate 8. At this time, release the moving plate 63. Under the restoring force of the spring 66, the block 676 extends out of the fixed column 2 and contacts the bottom surface of the slider 4. Under the restriction of the upper limit plate 8 and the block 676, the slider 4 can no longer move vertically, so the folding cart cannot be deformed either.

[0040] When wanting to store the folding cart, the staff presses two moving plates 63 and presses the two side plates 1 inwards at the same time. When the slider 4 moves to contact the lower limit plate 9, release the moving plate 63. The block 676 extends out of the fixed column 2 and contacts the top surface of the slider 4, and the slider 4 can no longer move vertically.

[0041] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
