Description

Technical Field

[0001] This utility model relates to the field of toy car technology, and more particularly to a toy car power mechanism. Background Technology

[0002] In existing technologies, some toy cars use the same motor to drive both the front and rear wheels, resulting in significant driving power. However, the motor in such a mechanism is typically placed in the middle of the casing. This means that when two motors are used together, they cannot overlap or be staggered within the toy car. Consequently, the width of the toy car cannot be effectively reduced, leading to increased material costs and hindering economic efficiency. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a toy car power mechanism.

[0004] To achieve the aforementioned objectives, this utility model provides a toy car power mechanism, including a housing, a motor, a front axle, and a rear axle. Both the front and rear axles are driven to rotate by the motor. A locking groove is provided at the rear center of the outer side of the housing, and the motor is fixed in the locking groove. An output gear is tightly fitted and fixed on the output shaft of the motor. Two transmission gear sets are meshed on the output gear. The end gears of the two transmission gear sets are coaxially fixed with the front axle and the rear axle, respectively. The transmission gear set connected to the front axle is arranged in a straight line within the housing, and the transmission gear set connected to the rear axle is arranged in a zigzag line within the housing.

[0005] As a preferred embodiment, the transmission gear set includes a first gear, a second gear, a third gear, a fourth gear, and a fifth gear that are meshed together in sequence. The first gears of the two transmission gear sets are respectively located on both sides of the output gear, the second gears of the two transmission gear sets are arranged on the lower left side of the corresponding first gear, and the fifth gears of the two transmission gear sets are coaxially fixed with the front wheel axle and the rear wheel axle.

[0006] As a preferred embodiment, the first gear, the third gear, and the fourth gear are double gears with the same structure, and the second gear and the fifth gear are single gears with different structures. The large gear of the first gear meshes with the output gear, the second gear meshes with the small gear of the first gear and the large gear of the third gear, the small gear of the third gear meshes with the large gear of the fourth gear, and the small gear of the fourth gear meshes with the fifth gear.

[0007] As a preferred embodiment, the tooth ratio of the double gear is 2:5, the tooth ratio of the large gear of the double gear to the output gear is 3:1, the tooth ratio of the small gear of the double gear to the second gear is 2:6, and the tooth ratio of the small gear of the double gear to the fifth gear is 3:8.

[0008] As a preferred embodiment, the housing includes a detachable and fixed first housing and a second housing, with the output gear and two transmission gear sets arranged and connected between the first housing and the second housing. The locking groove is provided at the rear of the middle of the outer side of the first housing, and the two ends of the second housing are respectively provided with an extension hole through which the front wheel axle and the rear wheel axle can pass.

[0009] As a preferred embodiment, the inner sidewall of the clamping groove is provided with a plurality of protruding ribs at intervals. The protruding ribs are used to clamp and fix the motor, thereby creating a heat dissipation gap between the motor and the bottom wall of the clamping groove.

[0010] As a preferred embodiment, the first housing and the second housing are fixedly connected by at least one of a snap-fit ​​structure, a threaded fastening structure, or an insertion structure.

[0011] Therefore, based on the technical means of this utility model, the effects that this utility model can achieve are briefly described as follows: The toy car power mechanism provided by this utility model meshes with two transmission gear sets, which are respectively fixed coaxially to the front wheel axle and the rear wheel axle, on the output gear. The transmission gear set connected to the front wheel axle is arranged in a straight line within the housing, while the transmission gear set connected to the rear wheel axle is arranged in a zigzag line within the housing. A locking groove is provided at a position slightly rearward from the center of the outer side of the housing, allowing the motor to be locked and fixed within the locking groove. The toy car power mechanism provided by this utility model redesigns the position of the motor and the arrangement of the two transmission gear sets, allowing the motor to be positioned slightly off-center. Furthermore, the arrangement of the two transmission gear sets is more reasonable and better suited to the motor's drive, resulting in relatively stable transmission. When this power mechanism is used in combination, the two motors can be staggered within the toy car, which helps to reduce the width distribution of the toy car, thereby saving material costs and achieving better economic benefits.

The terminology used in this specification of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the present invention.

[0018] Please refer to the following at the same time Figure 1-3 This embodiment provides a toy car power mechanism, including a housing 1, a motor 2, a front wheel axle 3 and a rear wheel axle 4, both of which are driven to rotate by the motor 2.

[0019] The housing 1 includes a detachable and fixed first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are fixedly connected by at least one of a snap-fit ​​structure, a threaded fixing structure, and a mating structure. In this embodiment, the first housing 11 and the second housing 12 are fixed using the above three structures. Specifically, the outer periphery of the first housing 11 is provided with a plurality of snap-fit ​​holes 131, countersunk holes 141, and mating holes 151 at intervals. The outer periphery of the second housing 12 is provided with a corresponding number of snap-fit ​​blocks 132, connecting holes 142, and mating posts 152 at corresponding positions. The snap-fit ​​holes 131 can be snapped onto the snap-fit ​​blocks 132, the countersunk holes 141 and the connecting holes 142 can be tightly fixed by screws or other threaded components, and the mating posts 152 can be inserted into the mating holes 151. Of course, in other embodiments, the first housing 11 and the second housing 12 can be fixed using any one or any two of the above three structures.

[0020] An output gear 51 and two transmission gear sets 2 are arranged and connected between the first housing 11 and the second housing 12. The output gear 51 and the two transmission gear sets 2 are used to drive the motor 2, the front wheel axle 3, and the rear wheel axle 4, so that when the motor 2 starts to rotate, it can simultaneously drive the front wheel axle 3 and the rear wheel axle 4 to rotate. It can be understood that a clamping groove 111 is provided at the rear of the middle of the outer side of the first housing 11. The inner sidewall of the clamping groove 111 is provided with multiple protruding ribs 112 at intervals. The protruding ribs 112 are used to clamp and fix the motor 2, so that there is a heat dissipation gap between the motor 2 and the bottom wall of the clamping groove 111, which helps the motor 2 to dissipate heat. The second housing 12 has an extension hole 121 at each end, through which the front wheel axle 3 and the rear wheel axle 4 can pass, so that the front wheel axle 3 and the rear wheel axle 4 can be rotatably set at both ends of the housing 1, which helps to fix the front wheel and the rear wheel at both ends of the housing 1.

[0021] An output gear 51 is tightly fitted and fixed to the output shaft of motor 2. Two transmission gear sets 52 are meshed on the output gear 51. The end gears of the two transmission gear sets 52 are coaxially fixed to the front wheel axle 3 and the rear wheel axle 4, respectively. The transmission gear set 52 connected to the front wheel axle 3 is arranged in a straight line within the housing 1, while the transmission gear set 52 connected to the rear wheel axle 4 is arranged in a zigzag line within the housing 1. It can be understood that by redesigning the distribution of motor 2 and the arrangement of the two transmission gear sets 52, the distribution of motors on housing 1 is more reasonable, and the arrangement of the two transmission gear sets 52 is more suitable for the positional distribution of motor 2, front wheel axle 3, and rear wheel axle 4. This helps to achieve a more rational and compact overall structure, resulting in higher space utilization and a more compact structure within housing 1.

[0022] In this embodiment, each transmission gear set 52 includes a first gear 521, a second gear 522, a third gear 523, a fourth gear 524, and a fifth gear 525 that are sequentially meshed together. The first gears 521 of the two transmission gear sets 52 are located on either side of the output gear 51, and the second gears 522 of the two transmission gear sets 52 are arranged to the lower left of the corresponding first gear 521. The fifth gears 525 of the two transmission gear sets 52 are coaxially fixed to the front axle 3 and the rear axle 4, respectively. It can be understood that the first gear 521, the third gear 523, and the fourth gear 524 are identical double gears, while the second gear 522 and the fifth gear 525 are different single gears. In this configuration, the large gear of the first gear 521 meshes with the output gear 51; the second gear 522 meshes with the small gear of the first gear 521 and the large gear of the third gear 523; the small gear of the third gear 523 meshes with the large gear of the fourth gear 524; and the small gear of the fourth gear 524 meshes with the fifth gear 525. This arrangement enables the transmission gear set 52 to form a gear set for speed reduction. Obviously, in other embodiments, the transmission gear set 52 can be composed of other numbers of gears meshing sequentially, and the number and structure of single and double gears in the transmission gear set 52 can be adjusted according to requirements.

[0023] In this embodiment, the tooth ratio of the double gear is 2:5, the tooth ratio between the large gear and the output gear 51 is 3:1, the tooth ratio between the small gear and the second gear 522 is 2:6, and the tooth ratio between the small gear and the fifth gear 525 is 3:8. Obviously, in other embodiments, the tooth ratio of the double gear and the tooth ratio between the double gear and other gears can be adjusted as needed.

[0024] 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.
