[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention.

[0026] Example 1

[0027] Reference Figure 1 to Figure 4 The present embodiment provides a belt-driven two-stage extension mechanism, including a driving component 100, the driving component 100 includes a motor 101, a motor driving wheel 102, a main belt 103 and a primary driving wheel 104, the motor driving wheel 102 is connected to the motor 101, and the main belt 103 connects the motor driving wheel 102 and the primary driving wheel 104; an extension component 200, the extension component 200 includes a main board 201, a primary extension plate 202 and a secondary extension plate 203, and the main board 201, the primary extension plate 202 and the secondary extension plate 203 are connected by a belt.

[0028] The motor 101, the motor driving wheel 102, the main belt 103 and the primary driving wheel 104 are all arranged on the main board 201, and the main board 201 is provided with a supporting structure or a lifting structure to fix it.

[0029] Furthermore, a primary driven wheel 201a is provided on the main board 201, and the primary driven wheel 201a is connected to the primary driving wheel 104 through a first belt 201b; a first slider 201c is provided at the bottom of the main board 201, and a first slide rail 202a is provided on the primary extension plate 202, and the first slide rail 202a is connected to the first slider 201c.

[0030] It should be noted that a slide groove is provided on the first slider 201c, and the first slide rail 202a is inserted into the slide groove. The first slide rail 202a can slide relative to the first slider 201c.

[0031] Furthermore, a first connecting block 202b is provided on one side of the primary extension plate 202, and the first connecting block 202b is connected to the first belt 201b.

[0032] Therefore, when the motor 101 is working, it can drive the main belt 103 and the motor driving wheel 102 to move, thereby causing the first belt 201b to move, the first connecting block 202b to move along the main board 201, and the first extension plate 202 to extend or retract.

[0033] Furthermore, a second slide rail 202c is provided at the bottom of the first extension plate 202, and a second slider 203a is provided on the second extension plate 203, and the second slider 203a is connected to the second slide rail 202c.

[0034] Likewise, a slide groove is provided in the second sliding block 203a, and the second slide rail 202c passes through the slide groove.

[0035] The first-level extension plate 202 is provided with a first-level wheel 202d and a second-level wheel 202e, and the first-level wheel 202d and the second-level wheel 202e are connected by a second belt 202f; a second connecting block 201d is provided on one side of the main board 201, and the second connecting block 201d is connected to the second belt 202f; a third connecting block 203b is provided on one side of the secondary extension plate 203, and the third connecting block 203b is connected to the second belt 202f.

[0036] When the primary extension plate 202 moves relative to the main plate 201, the second connecting block 201d drives the second belt 202f to move, thereby moving the third connecting block 203b, so that the secondary extension plate 203 extends or retracts.

[0037] It should be noted that the second connecting block 201d is arranged on the upper layer of the second belt 202f, and the third connecting block 203b is arranged on the lower layer of the second belt 202f, so that when the second belt 202f moves, the movement directions of the second connecting block 201d and the third connecting block 203b are opposite; and in order to ensure normal movement, the second connecting block 201d and the third connecting block 203b are respectively arranged close to the first secondary wheel 202d and the second secondary wheel 202e.

[0038] In this way, a servo motor can be driven in the forward direction to drive the first belt 201b and the second belt 202f to be linked, so that the first extension plate, the second extension plate, the first extension plate 202 and the second extension plate 203 are extended at the same time. When the motor is reversed, it drives the first belt 201b and the second belt 202f to be linked, so that the first extension plate 202 and the second extension plate 203 are retracted at the same time.

[0039] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
