Abstract:
A toy car structure in which a power source such as a motor is activated to drive a gear set for driving decorative car doors, engine hood and car light cover bodies of a car body to open or close so as to create versatile operation.

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a toy car structure, and more particularly to a transmission mechanism of a toy car, which is able to drive multiple operation elements to open or close during running of the car body so as to create versatile operation. 
     A conventional toy car is designed with attractive appearance and simple operation (such as running of the car body and sound/light effect) for achieving entertaining effect. However, the transmission mechanism of such toy car is unable to create versatile operations so that the conventional toy car can hardly satisfy the requirement of children. In order to solve this problem, some toy cars are designed with a transmission mechanism which is able to create versatile operations. However, such transmission mechanism is quite complicated so that the cost for the toy car is relatively high and the malfunction possibility of the toy car is increased. 
     SUMMARY OF THE INVENTION 
     It is therefore a primary object of the present invention to provide a toy car which is manufactured at low cost, while able to create versatile operations. 
     The present invention can be best understood through the following description and accompanying drawings wherein:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Please refer to FIGS. 1 and 2. A base seat 3 is disposed on the bottom of a car body 2. A casing 1 is mounted on the base seat 3. A first power source 11 such as a motor is disposed in the casing 1. The first power source 11 via a gear set 12 is drivingly connected with a vertical connecting rotary shaft 12. The bottom end of the rotary shaft 12 extends out of the casing 1 and the car body 2 and connected with a rotary power wheel set 4. Both a transmission gear 131 is fixedly fitted, and a driving wheel 14 is loosely fitted onto the rotary shaft 13 transmission gear 131 meshes with a connecting gear 121. The driving wheel 14 is driven by a second power source 15 to drive a driving gear 16. Two ends of one side of the casing 1 are respectively formed with perforations 17 between which a transverse rack 18 is bridged. The rack 18 is drivingly engaged with the driving gear 16. One end section of the rack 18 is formed with a pushing edge 181 and disposed with an upward extending post 182. The pushing edge 181 serves to drive a driving block 19 disposed outside the casing 1. The driving block 19 is disposed with a pushing projection 191 and a hook section 192 at rear end. Via a resilient member 193, the hook section 192 is hooked on the base seat 3. 
     Referring to FIGS. 3 and 4, the base seat 3 is disposed with a first and a second linking members 31, 32 on two sides of an end section of the casing 1. Each of the first and second linking members 31, 31 has a longer arm and a shorter arm and are mounted at junctures on 33 of the base seat 3 as fulcrums. The end section of the longer arm of the first linking member 31 is disposed with a post 311 and a slot 312 adjacent to the post 311. The post 182 of the end section of the rack 18 extends into the slot 312 to drive the first linking member 31 back and forth. The end section of the longer arm of the second linking member 32 is formed with a slot 321. The post 311 of the first linking member 31 extends into the slot 321 to drive the second linking member. The shorter arm of each of the linking members 31, 32 via a fixing member 34 is connected with a resilient linking member 35. An end section of the resilient linking member 35 clamps a post 361 of a pushing member 36 disposed on the support posts 37 on two sides of the casing 1. At least one pushing member 36 is disposed with an extending short arm formed with a slot 362. The base seat 3 is formed with a guide slot 38 below the slot 362. A guide member 39 is received in the guide slot 38. One end of the guide member 39 is formed with a perforation 391. The other end thereof is disposed with an upward extending post 392 extending into the slot 362. 
     At least one decorative car light cover body 5 is disposed with a downward extending driving arm 51. The bottom end of the driving arm 51 is connected with a beam 53 and connected on the base seat 3 with a fixing seat 30 of the base seat 3 as a fulcrum. The driving arm 51 is disposed with a driving post 52 extending into the perforation 391 of the guide member 39 to be driven thereby to upward move and open or downward move and close the car light cover body 5. The post 52 is disposed with a hook which via a resilient member 54 is hooked on the base seat 3. The base seat 3 is disposed with a decorative car light 55 corresponding to the car light cover body 5. The car body 2 is formed with a through hole 23 corresponding to the car light 55. 
     Each end section of a decorative engine hood 6 is disposed with a projection which serves as a fulcrum 61 and extends into the fixing socket 21 of the car body 2. The hood 6 is disposed with a hook 62 which via a resilient member 63 is hooked on the base seat 3. The hood 6 is disposed with a downward extending pushing member 64 pushed by the pushing projection 191 of the driving block 19. When the driving block 19 is moved back and forth, the engine hood 6 is driven upward and open or downward and closed. 
     One side of a decorative car door 7 is disposed with a pivot shaft 71 which serves as a fulcrum and is disposed in a pivot seat 22 of the car body 2. A hook 72 is disposed on the car door 7 near the pivot shaft 71, which via a resilient member 73 is hooked on the car body 2. When the first and second linking members 31, 32 operate, the pushing member 36 is driven to push the car door 7 to move forward and open or move backward and close. 
     According to the above arrangement, after the first power source 11 is turned on, the gear set 12 is driven to continuously drive the connecting gear 121 for driving the rotary shaft 13 to rotate. At this time, the rotary power wheel set 4 is driven and the toy car can run over when touching the ground. Also, the second power source 15 in the casing 1 drives the driving gear 16 to move the rack 18 back and forth so as to drive the first and second linking members 31, 32 on the casing 1 to swing back and forth. At this time, the pushing member 36 is driven to push outward the car door 7 and open the car door. Also, the pushing member 36 drives the guide member 39 so as to drive the car light cover body 5 up and down and open and close. In addition, when the rack 18 drives the first and second linking members 31, 32, the driving block 19 is also driven to slide back and forth. At this time, the pushing edge 191 of the driving block 19 pushes the pushing member 64 of the engine hood 6 so as to open and close the engine hood 6. 
     The above embodiment is only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiment can be made without departing from the spirit of the present invention.
