Description
Technical Field
[0001] This utility model belongs to the technical field of electric toy accessories, specifically the swing mechanism for electric toys. Background Technology
[0002] Electric toys are motorized toys driven by miniature electric motors. Most of them use batteries as their power source, converting electrical energy into mechanical energy to achieve movement. They combine entertainment and interactivity and are an important part of the children's toy market.
[0003] In some toy types such as bobblehead toys, rocking cars, and dancing robot toys, it is necessary for the toy to make periodic reciprocating rocking motions. In this case, a rocking mechanism needs to be installed inside the toy to make the toy parts rock. Existing rocking mechanisms include crank-connecting rod structures, cam-pull rod structures, gear and rack structures, etc. By driving the crank, cam, and gear to rotate through the motor, the toy parts can be made to swing. However, the swing arm connection of the rocking mechanism is usually mounted on a fixed shaft. When the swing arm rotates, it will generate a lot of friction with the shaft, which will cause wear between the swing arm and the shaft.
[0004] Therefore, this utility model provides a rocking mechanism for electric toys. Utility Model Content
[0005] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a rocking mechanism for electric toys is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The swing mechanism for electric toys of this utility model includes a shell, a cover plate fixed to the shell by screws, a motor installed inside the shell, a fixing component and a limiting component provided inside the shell, a turntable installed at the output end of the motor, a fixing rod fixedly connected to the turntable, the fixing rod and the turntable having an eccentric structure, a rotating shaft fixedly connected to the shell, a swing arm rotatably connected to the rotating shaft, anti-wear components provided on both the fixing rod and the swing arm, a sliding groove provided on the swing arm, a clamping component provided on the rotating shaft, and a vibration damping component provided on the motor. Through the above structure, the motor drives the turntable and the fixing rod to rotate, which in turn drives the swing arm to perform reciprocating swinging motion outside the shell. By integrating the entire mechanism onto the shell, the overall structure can be made more compact and space occupancy can be reduced.
[0007] Preferably, the anti-wear component includes two sets of bearings, which are respectively installed in the middle of the fixed rod and inside the swing arm. A pair of slots are provided in the bearings, and a pair of retaining strips are provided on the rotating shaft and the fixed rod respectively. The slots and retaining strips are interference fit. With the above structure, the two sets of bearings are respectively installed on the fixed rod and the swing arm, which can reduce the friction between the fixed rod and the slide groove and the friction between the swing arm and the rotating shaft, thereby reducing the situation of excessive wear caused by friction.
[0008] Preferably, the clamping assembly includes a baffle plate, which is fixedly connected to the side wall of the rotating shaft. A pressure cap is connected to the end of the rotating shaft by screws. Both the side wall of the baffle plate and the pressure cap are fixedly connected with a protrusion. Through the above structure, the protrusion contacts the inner ring of the bearing, so that there is a gap between the swing arm and the baffle plate and the pressure cap when the swing arm is fixed on the rotating shaft, thereby reducing the wear caused by friction between the side wall of the swing arm and the baffle plate and the pressure cap when the swing arm rotates.
[0009] Preferably, the fixing component includes a fixing ring disposed inside the housing, and a pressure plate is provided on the side wall of the cover plate. Through the above structure, the fixing ring and the pressure plate are fixed by compression to install the motor inside the housing, which can improve the convenience of motor installation.
[0010] Preferably, the limiting component includes a positioning tube disposed inside the housing, and a positioning rod is provided on the side wall of the cover plate. The positioning tube and the positioning rod have rectangular cross-sections. Through the above structure, the positioning tube and the positioning rod limit the position between the housing and the cover plate, which can improve the convenience of aligning the housing and the cover plate, thereby improving the installation efficiency between the housing and the cover plate.
[0011] Preferably, the vibration damping component includes a high-elasticity silicone sleeve, which is fitted onto the outside of the motor. With the above structure, the high-elasticity silicone sleeve is located between the motor and the fixed ring, and its elastic material can play a certain role in vibration damping.
[0012] Preferably, the fixing ring has multiple through slots that are evenly distributed on the fixing ring. With the above structure, the multiple through slots on the fixing ring can help dissipate the heat generated during the operation of the motor.
[0013] The beneficial effects of this utility model are as follows: 1. The rocking mechanism for electric toys described in this utility model drives the turntable and the fixed rod to rotate via a motor, which in turn drives the swing arm to perform reciprocating rocking motion outside the outer shell. By integrating the entire mechanism onto the outer shell, the overall structure can be made more compact and space occupancy can be reduced.
[0014] 2. The rocking mechanism for electric toys described in this utility model is mounted on the fixed rod and the rocking arm respectively by two sets of bearings. This reduces the friction between the fixed rod and the slide groove and the friction between the rocking arm and the rotating shaft, thereby reducing the wear caused by friction.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Specific implementation examples are given below.
[0020] like Figures 1 to 5As shown in the embodiment of this utility model, the rocking mechanism for an electric toy includes a housing 1, a cover plate 11 fixed to the housing 1 by screws, a motor 12 installed inside the housing 1, a fixing component and a limiting component provided inside the housing 1, a turntable 13 installed at the output end of the motor 12, a fixing rod 14 fixedly connected to the turntable 13, the fixing rod 14 and the turntable 13 having an eccentric structure, a rotating shaft 15 fixedly connected to the housing 1, a swing arm 16 rotatably connected to the rotating shaft 15, anti-wear components provided on both the fixing rod 14 and the swing arm 16, a sliding groove 17 provided on the swing arm 16, a clamping component provided on the rotating shaft 15, and a clamping component provided on the motor 12. In operation, the vibration damping assembly involves installing the motor 12 in a fixed assembly inside the housing 1, then fixing the cover plate 11 to the housing 1 with screws, connecting the turntable 13 to the output end of the motor 12, and then mounting the swing arm 16 on the rotating shaft 15 and fitting the slide groove 17 onto the fixed rod 14. The motor 12 drives the turntable 13 and the fixed rod 14 to rotate. When the fixed rod 14 makes an eccentric motion, it drives the swing arm 16 to make a reciprocating swing motion. Through the above structure, the motor 12 drives the turntable 13 and the fixed rod 14 to rotate, which in turn drives the swing arm 16 to make a reciprocating swing motion outside the housing 1. By integrating the entire mechanism onto the housing 1, the overall structure can be made more compact and space occupancy can be reduced.
[0021] like Figure 4 and Figure 5 As shown, the anti-wear component includes two sets of bearings 2, which are respectively installed in the middle of the fixed rod 14 and inside the swing arm 16. A pair of slots 21 are provided in the bearing 2. A pair of retaining strips 22 are respectively provided on the rotating shaft 15 and the fixed rod 14. The slots 21 and retaining strips 22 are interference fit. During operation, the two sets of bearings 2 are respectively installed on the fixed rod 14 and the swing arm 16. Then, the bearings 2 on the swing arm 16 are installed on the rotating shaft 15. When the fixed rod 14 rotates, it will drive the bearings 2 on its surface to rotate in the inner wall of the slide groove 17. At this time, the friction between the fixed rod 14 and the slide groove 17 can be reduced. When the swing arm 16 rotates, it will drive the bearings 2 inside it to rotate, thereby reducing the friction between the swing arm 16 and the rotating shaft 15. Through the above structure, the two sets of bearings 2 are respectively installed on the fixed rod 14 and the swing arm 16. At this time, the friction between the fixed rod 14 and the slide groove 17 and the friction between the swing arm 16 and the rotating shaft 15 can be reduced, thereby reducing the situation of excessive wear caused by friction.
[0022] like Figure 5As shown, the clamping assembly includes a baffle 3, which is fixed to the side wall of the rotating shaft 15. The end of the rotating shaft 15 is connected to a pressure cap 31 by screws. Both the side walls of the baffle 3 and the pressure cap 31 are fixed with protrusions 32. During operation, when the bearing 2 inside the swing arm 16 is installed on the rotating shaft 15, the bearing 2 is first put on the rotating shaft 15, and then the pressure cap 31 is fixed to the end of the rotating shaft 15 by screws. At this time, the inner ring of the bearing 2 will contact the side wall of the protrusion 32, and the swing arm 16 will be lowered and fixed on the rotating shaft 15 by the clamping action of the baffle 3, the pressure cap 31 and the protrusion 32. Through the above structure, the protrusion 32 contacts the inner ring of the bearing 2, so that there is a gap between the swing arm 16 and the baffle 3 and the pressure cap 31 when it is fixed on the rotating shaft 15, thereby reducing the wear caused by friction between the side wall of the swing arm 16 and the baffle 3 and the pressure cap 31 when it rotates.
[0023] like Figure 2 and Figure 3 As shown, the fixing component includes a fixing ring 4, which is disposed inside the outer casing 1. The side wall of the cover plate 11 is provided with a pressure plate 41. During operation, the motor 12 is inserted into the fixing ring 4. At this time, the vibration damping component on the surface of the motor 12 is tightly fitted with the inner wall of the fixing ring 4. Then, the cover plate 11 is fixed to the outer casing 1 with screws. At this time, the pressure plate 41 on the cover plate 11 will press down on the bottom of the motor 12, thus fixing the motor 12 inside the fixing ring 4. Through the above structure, the fixing ring 4 and the pressure plate 41 are fixed by compression to install the motor 12 inside the outer casing 1, which can improve the convenience of motor 12 during installation.
[0024] like Figure 2 and Figure 3 As shown, the limiting component includes a positioning tube 5, which is disposed inside the outer shell 1. The cover plate 11 has a positioning rod 51 on its side wall. The positioning tube 5 and the positioning rod 51 have rectangular cross-sections. During operation, when connecting the outer shell 1 and the cover plate 11, the positioning rod 51 and the positioning tube 5 are aligned and inserted. This fixes the position between the outer shell 1 and the cover plate 11 and aligns the screw holes on the cover plate 11 with the studs inside the outer shell 1. Through the above structure, the positioning tube 5 and the positioning rod 51 limit the position between the outer shell 1 and the cover plate 11, which improves the convenience of aligning the outer shell 1 and the cover plate 11 and thus improves the installation efficiency between the outer shell 1 and the cover plate 11.
[0025] like Figure 4 As shown, the vibration damping component includes a high-elasticity silicone sleeve 6, which is fitted onto the outside of the motor 12. During operation, the high-elasticity silicone sleeve 6 is fitted onto the outside of the motor 12. After the motor 12 is installed inside the fixing ring 4, the high-elasticity silicone sleeve 6 is in close contact with the inner wall of the fixing ring 4. Through the above structure, the high-elasticity silicone sleeve 6 is located between the motor 12 and the fixing ring 4, and its elastic material can play a certain role in vibration damping.
[0026] like Figure 4 As shown, the fixed ring 4 has multiple through slots 7, which are evenly distributed on the fixed ring 4. When the motor 12 rotates and generates heat, some of the heat will be dissipated from the through slots 7 on the fixed ring 4. Through the above structure, the multiple through slots 7 on the fixed ring 4 can help dissipate the heat generated by the motor 12 during operation.
[0027] Working principle: The motor 12 is installed in the fixed assembly inside the housing 1. Then, the cover plate 11 is fixed to the housing 1 with screws. The turntable 13 is connected to the output end of the motor 12. The swing arm 16 is installed on the rotating shaft 15 and the slide groove 17 is fitted onto the fixed rod 14. The motor 12 drives the turntable 13 and the fixed rod 14 to rotate. When the fixed rod 14 makes an eccentric motion, it will drive the swing arm 16 to make a reciprocating swing motion. Two sets of bearings 2 are installed on the fixed rod 14 and the swing arm 16 respectively. Then, the bearings 2 on the swing arm 16 are installed on the rotating shaft 15. When the fixed rod 14 rotates, it will drive the bearings 2 on its surface to rotate on the inner wall of the slide groove 17. This can reduce the friction between the fixed rod 14 and the slide groove 17. When the swing arm 16 rotates, it will drive the bearings 2 inside it to rotate, thereby reducing the friction between the swing arm 16 and the rotating shaft 15. When the bearings 2 inside the swing arm 16 are installed on the rotating shaft 15, the bearings 2 are first fitted onto the rotating shaft 15, and then the pressure cap 31 is connected to the rotating shaft 15. 5. The end is fixed with screws. At this time, the inner ring of bearing 2 will contact the side wall of the protrusion 32. Under the clamping action of the baffle 3, the pressure cap 31 and the protrusion 32, the swing arm 16 is lowered and fixed on the rotating shaft 15. The motor 12 is inserted into the fixing ring 4. At this time, the vibration damping component on the surface of the motor 12 is tightly fitted with the inner wall of the fixing ring 4. Then, the cover plate 11 is fixed to the outer shell 1 with screws. At this time, the pressure plate 41 on the cover plate 11 will press down on the bottom of the motor 12. At this time, the motor 12 can be fixed in the fixing ring 4. When connecting the outer shell 1 to the cover plate 11, the positioning rod 51 is aligned with the positioning tube 5 and inserted. At this time, the position between the outer shell 1 and the cover plate 11 can be fixed, and the screw holes on the cover plate 11 can be aligned with the studs inside the outer shell 1. The high-elastic silicone sleeve 6 is put on the outside of the motor 12. After the motor 12 is installed in the fixing ring 4, the high-elastic silicone sleeve 6 is in close contact with the inner wall of the fixing ring 4. When the motor 12 rotates and generates heat, some of the heat will be dissipated from the through groove 7 on the fixing ring 4.
