Description

Technical Field

[0001] The utility model belongs to the technical field of toys, and particularly relates to a toy crawling baby. Background Art

[0002] At present, there are many toy dolls with various shapes on the market, which are deeply loved by children. For example, the utility model with the publication number "CN207126114U" and the name of "Intelligent Crawling Baby" discloses an intelligent crawling baby, which includes a bionic trunk, two bionic legs, a bionic head, a second driving mechanism, and a second transmission mechanism driven by the second driving mechanism. The rear end of the bionic trunk is connected with a bionic buttocks. A first driving mechanism and a first transmission mechanism driven by the first driving mechanism are arranged in the bionic trunk and the bionic buttocks. The first transmission mechanism includes two output cams that can respectively act on the left and right sides of the bionic buttocks to drive the bionic buttocks to swing left and right relative to the bionic trunk. The two bionic legs are respectively connected to the left and right sides of the rear part of the bionic buttocks. By setting independent first and second driving mechanisms and first and second transmission mechanisms to cooperate to realize the movement of the doll, the structure is relatively complex, the cost is high, and a battery is required. After playing for a period of time, the battery needs to be replaced. Therefore, there is a need for a toy crawling baby with a simple structure, low cost, and can be played without a battery on the market. Summary of the Utility Model

[0003] Aiming at the above deficiencies, the purpose of the utility model is to provide a toy crawling baby with reasonable design, driven by a spring, and high interest.

[0004] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0005] A toy crawling baby includes a head, an upper body part, a lower body part, a spring device, a driving wheel, a front wheel, a rear wheel, a connecting seat and a linkage frame. The head is arranged on the upper body part. The connecting seat is arranged at the tail of the upper body part. The lower body part is hinged to the connecting seat.

[0024] Embodiment: Refer to Figures 1 to 9 , this embodiment provides a toy crawling baby, which includes a head 1, an upper body 2, a lower body 3, a spring device 4, a driving wheel 5, a front wheel 6, a rear wheel 7, a connecting seat 8 and a linkage 9.

[0025] The head 1 is arranged at the front position of the upper body 2, and the front wheel 6 is arranged at the front bottom surface of the upper body 2. Specifically, there are two horizontally forward-extending arms 21 on the upper body 2, and a feeding bottle 10 is arranged between the two arms 21. The feeding bottle 10 can be fixed to the bottom surface of the head 1 or on the two arms 21. The front wheel 6 is arranged on the feeding bottle 10 through a wheel axle. Two arms 21 and a feeding bottle decoration are added, and the front wheel 6 is cleverly placed under the feeding bottle 10, which serves as a support point and adds a visual effect to the toy, making the appearance of the toy more vivid and lovely.

[0026] The connecting seat 8 is arranged at the tail of the upper body 2. Specifically, a connecting portion 22 is arranged at the upper edge position of the tail of the upper body 2, and a connecting cavity 81 adapted to the connecting portion 22 is arranged on the connecting seat 8. The connecting portion 22 extends into the connecting cavity 81 and is connected by a hinge shaft. The connecting seat 8 can rotate a certain angle around the hinge shaft to facilitate the arching and sinking movements in cooperation with the lower body 3.

[0027] The lower body 3 is hinged to the connecting seat 8. Specifically, hinge protrusions 82 are symmetrically arranged on both sides of the lower edge of the tail of the connecting seat 8, and hinge concave holes 32 adapted to the hinge protrusions 82 are arranged on the lower body 3. Through the cooperation of the hinge protrusions 82 and the hinge concave holes 32, the lower body 3 can swing up and down, and the connection stability is good. To limit the excessive swing of the lower body 3, an arc surface portion is formed by bending the upper edge of the tail of the connecting seat 8 downward, and a limit clamping protrusion 31 adapted to the arc surface portion is arranged on the upper part of the lower body 3. Through the cooperation of the limit clamping protrusion 31, the stability of the toy during movement is improved.

[0028] The rear wheel 7 is arranged at the bottom surface of the tail of the lower body 3. Preferably, the number of the rear wheels 7 is two, and the lower body 3 has two legs, and the two rear wheels 7 are correspondingly arranged on the two legs. The balance of the toy is improved, and the crawling process looks more natural and smooth, enhancing the simulation degree of the toy.

[0029] The spring device 4 is arranged at the tail of the upper body part 2, and output shafts 41 are arranged on both sides of the spring device 4. Specifically, the spring device 4 includes a gear box 42 and a spring shaft 43, an energy storage spring 44, a driving pawl 45, a first gear 46, a second gear 47, a third gear 48, a first reduction gear 49, a second reduction gear 410 and a reduction component 411 arranged in the gear box 42. The output shaft 41 is located at the lower part of the gear box 42 and extends out of the gear box 42 at both ends. The third gear 48 is fixed at the middle position of the output shaft 41. The driving pawl 45 is fixed on the spring shaft 43. The outer ring end of the energy storage spring 44 is fixed on the gear box 42, and the inner ring end of the energy storage spring 44 is fixed on the driving pawl 45 or the spring shaft 43. The first gear 46 is movably arranged on the spring shaft 43, and a mating cavity 461 is arranged on the surface facing the driving pawl 45. Ratchet teeth 462 adapted to the driving pawl 45 are arranged on the cavity wall of the mating cavity 461. The second gear 47 meshes with the first gear 46 and the third gear 48 respectively. The second gear 47, the first reduction gear 49 and the second reduction gear 410 are meshed in sequence. The reduction component 411 is arranged in the gear box 42 through a rotating shaft at a position corresponding to the second reduction gear 410. On both sides of one end of the reduction component 411, a reduction pawl 4111 that can abut against the second reduction gear 410 during its rotation is symmetrically arranged. By the damping effect generated by the reduction pawl 4111 abutting against the second reduction gear 410, the rotation speed of the second reduction gear 410 can be slowed down, making the crawling action smoother.

[0030] The driving wheel 5 is arranged on the output shaft 41 and exposed from the bottom surface of the upper body part 2. An eccentric shaft 51 is arranged on the driving wheel 5. One end of the linkage 9 is connected to the eccentric shaft 51, and the other end is hinged to the lower body part 3. The hinge point 34 of the linkage 9 and the lower body part 3 is located at the rear side position of the hinge concave hole 32.

[0031] For convenient winding of the spring, a handle 412 is arranged on the spring shaft 43. By turning the handle 412 to rotate several circles for the spring winding action, the energy storage spring 44 stores energy. At this time, although the driving pawl 45 also rotates as the spring shaft 43 rotates, the driving pawl 45 slides with the ratchet teeth 462 of the first gear 46, making the first gear 46 immovable.

[0032] After being wound up, place the present utility model flat on the tabletop. Then, the energy storage spring 44 releases energy to drive the spring shaft 43 to rotate. The spring shaft 43 drives the driving pawl 45 to reverse. At this time, the driving pawl 45 locks with the ratchet teeth 462 of the first gear 46, realizing driving the first gear 46 to rotate. Through the transmission of the second gear 47 and the third gear 48, the driving wheel 5 is further driven to rotate, thereby achieving the purpose of the whole body crawling forward. At the same time, the rear wheel 7 cooperates with the linkage 9 through the eccentric shaft 51 to drive the lower body 3 to continuously arch and sink, which not only enhances the simulation degree of the toy but also makes the crawling process look more natural and smooth, showing better fun. Moreover, without the need for batteries or external energy sources, the power source can be provided through the spring device 4, which is environmentally friendly and can be played at any time and anywhere.
