[0024] As Figures 1-5 shown, the present embodiment provides a compact driving structure for a slide toy, which comprises a driving device 1 and a slide plate 2 driven by the driving device 1 to move up and down reciprocally, wherein the slide plate 2 is arranged adjacent to a side plate, and the side plate is used to cooperate with the slide plate 2 to realize the conveying of rolling bodies.

[0025] The driving device 1 comprises a housing 11, a motor 12, a gear set 13 and an eccentric wheel 14, wherein the housing 11 is internally provided with a vertical first inner cavity 11a and a second inner cavity 11b, the motor 12 is fixedly connected in the first inner cavity 11a, the gear set 13 is rotationally connected in the second inner cavity 11b, and the eccentric wheel 14 is externally arranged on the housing 11.

[0026] It can be understood that the shape of the first inner cavity 11a is consistent with the shape of the motor 12, and the width of the second inner cavity 11b is slightly larger than the rotating diameter of the largest gear in the gear set 13, so as to ensure that the gear set 13 can normally rotate in the second inner cavity 11b without interfering with the inner wall of the second inner cavity 11b. The above arrangement can improve the utilization rate of the inner cavity of the housing 11, reduce space waste, and further improve the structural compactness of the driving device 1, the size is small, and it is more convenient to install in a small slide toy. Similarly, it can also be installed in a slightly larger size slide toy, and the applicability is higher.

[0027] The housing 11 comprises a first housing 111 and a second housing 112 which are detachably connected. In the embodiment, a first notch 113 is formed in the side end wall of the first housing 111, a second notch 114 is formed in the side end wall of the second housing 112, and the first notch 113 and the second notch 114 can be spliced to form a window 11c. The window 11c is beneficial to heat dissipation, and also facilitates auxiliary operations such as dropwise adding lubricating liquid. It can be understood that the length of the cavity wall of the second inner cavity 11b in the first housing 111 is less than the length of the cavity wall of the second inner cavity 11b in the second housing 112, and the cavity wall of the second inner cavity 11b of the second housing 112 covers the gear set 13. The above arrangement can further reduce the space waste of the housing 11, save production materials, and reduce production cost. In other embodiments, the window 11c can not be provided on the housing 11, and the second inner cavity walls of the first housing 111 and the second housing 112 can have the same length value.

[0028] In the embodiment, two first mounting columns 115 are arranged adjacent to the cavity wall of the second inner cavity 11b in the first housing 111, and the connecting line of the two first mounting columns 115 is perpendicular to the axis of the rotating shaft of the motor 12.

The above arrangement can limit the gears of the gear set 13 to be distributed in a straight line shape perpendicular to the motor 12, so that the width of the second inner cavity 11b can only consider the rotating diameter of the largest gear in the gear set 13, the width limitation of the second inner cavity 11b is shortened, the space waste is reduced, and the structural compactness of the driving device 1 is further improved. In other embodiments, the number of the first mounting column 115 and the second mounting column 116 can be adjusted to three or more than four according to the number of gears of the gear set 13.

[0029] It can be understood that the shell 11 is provided with a first opening 117 and a second opening 118 on the cavity wall of the first inner cavity 11a, the first opening 117 is opened corresponding to the terminal of the motor 12, so that the terminal can be exposed on the shell 11, to facilitate the circuit connection of the motor 12. The second opening 118 is opened corresponding to the body of the motor 12, for increasing the heat dissipation area of the motor 12, and reducing the probability of thermal damage of the motor 12.

[0030] In the embodiment, the shell 11 is provided with a first fixing structure on the outer wall of the first inner cavity 11a and the second inner cavity 11b respectively, and the shell 11 is provided with a second fixing structure in the second inner cavity 11b, and the first fixing structure and the second fixing structure are used to realize the detachable connection of the first shell 111 and the second shell 112. The first fixing structure includes the plug-in column 31 and the plug-in slot 32 arranged between the first shell 111 and the second shell 112, and the second fixing structure includes the fixing column 41 and the counterbore 42 arranged between the first shell 111 and the second shell 112. The plug-in column 31 and the plug-in slot 32 are connected in plug-in cooperation, and the fixing column 41 and the counterbore 42 are connected in detachable fixing by screws or bolts. In other embodiments, only the first fixing structure or the second fixing structure can be arranged between the first shell 111 and the second shell 112, or other detachable connection structures such as buckle structures can be used.

[0031] The gear set 13 is drivingly connected between the motor 12 and the eccentric wheel 14. In the embodiment, the gear set 13 includes a worm gear 131, a variable speed gear 132 and a driving gear 133. The worm gear 131 is fixed on the rotating shaft of the motor 12, and the variable speed gear 132 is engaged with the worm gear 131 and the driving gear 133 respectively. It can be understood that in order to make the final output rotating speed of the gear set 13 applicable to various types of slide toys smoothly, the total transmission ratio of the gear set 13 is set to be greater than 12. In other embodiments, more than one gear can be additionally arranged in the gear set 13.

[0032] It can be understood that the variable speed gear 132 includes a first tooth 1321 and a second tooth 1322 fixed coaxially, the number of teeth of the first tooth 1321 is greater than that of the second tooth 1322, and in the embodiment, the number of teeth of the first tooth 1321 is 26, and the number of teeth of the second tooth 1322 is 12.

In other embodiments, the number of teeth of each gear in the gear set 13 can be adaptively adjusted according to the value of the total transmission ratio.

[0033] An eccentric post 141 is eccentrically provided on the eccentric wheel 14. The post 141 is slidably connected to the elongated hole of the slide plate 2. When the eccentric wheel 14 rotates, the post 141 can reciprocate in the elongated hole, thereby driving the slide plate 2 to reciprocate up and down in the vertical direction.

[0034] Specifically, both the top of the slide plate 2 and the side plate have multi-layered stepped structures 21, and the side end of the slide plate 2 has an elongated hole 22. The multi-layered stepped structures of the slide plate 2 and the side plate correspond one-to-one, and a protruding post 141 is slidably connected within the elongated hole 22. For example... Figure 5 As shown, in this embodiment, each step structure of the slide plate 2 and the side plate is provided with a sliding surface. The sliding surface of the slide plate 2 is inclined to the side plate, and the sliding surface of the side plate is inclined to the slide plate 2. This is so that during the reciprocating movement of the slide plate 2, the rolling body at the lower end can roll to the higher end under the guidance of the sliding surfaces of the slide plate 2 and the side plate until it reaches the top.

[0035] like Figure 6 As shown, in other embodiments, each step structure of the slide plate 2 and the side plate can be configured as an inclined sawtooth shape, so that during the reciprocating movement of the slide plate 2, the rolling body at the lower end can be driven by the sawtooth step at the lower end to move to the higher end until it reaches the top.

[0036] For clarity, certain features described in individual embodiments of the present invention may be used in combination in a single embodiment. Furthermore, various features of the present invention described in individual embodiments may also be used individually or in any suitable form in sub-combinations.
