Abstract
Description
Technical Field
[0001] This utility model relates to the field of toy technology, specifically to a toy assembly structure and a toy. Background Technology
[0002] In existing technologies, the assembly of wheels and axles generally uses a shaft-hole mating structure, such as... Figure 3 As shown, adding a plug-like limiting component to the outside of the axle to prevent the wheel from falling off, or making the wheel and axle tightly fitted so that the axle and wheel rotate together, and using a knurled plastic structure to fit the wheel and axle to enhance the tight fit, all these designs have drawbacks. On the one hand, adding limiting components increases the number of parts, making assembly more difficult and uneconomical. On the other hand, using a knurled tight fit between the wheel and axle can lead to wear inside the wheel hole after repeated disassembly and assembly, eventually causing assembly failure, reducing the toy's stability and affecting its lifespan. Utility Model Content

[0005] The first building block has an axle, and the axle is provided with a boss along the circumferential direction;
[0006] The second building block has a hole with a groove that matches the boss, and the shaft can be fitted into the hole and the boss is located in the groove when assembled.
[0007] The boss has a first slope and a second slope on its two sides respectively. The angle between the first slope and the axis of the shaft is smaller than the angle between the second slope and the axis of the shaft. The first slope is closer to the end of the shaft than the second slope.

The slope of the first slope near the shaft end is smaller than that of the second slope far from the shaft end.

[0032] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0033] Example 1:
[0034] To address the problems of numerous parts, cumbersome assembly, and unstable assembly in shaft-hole assembly structures, this utility model provides a toy assembly structure, such as... Figure 1 , Figure 2 As shown, the assembly includes a first block 1 and a second block 2. The first block 1 has a shaft 11 with a boss 111 along the circumferential direction. The second block 2 has a hole 21 with a groove 211 that matches the boss 111. The shaft 11 can be fitted into the hole 21, and when the shaft 11 is in place, the boss 111 is exactly located in the groove 211. The groove 211 limits the boss 111, making the shaft 11 more stable in the hole 21.
[0035] Specifically, a first ramp 112 and a second ramp 113 are respectively provided on both sides of the boss 111. The angle between the first ramp 112 and the axis of the shaft 11 is smaller than the angle between the second ramp 113 and the axis of the shaft 11. That is, the slope of the first ramp 112 is smaller than the slope of the second ramp 113. The first ramp 112 is closer to the end of the shaft 11 than the second ramp 113.
[0036] Furthermore, such as Figure 2 As shown, the above structural design ensures that when the shaft 11 is assembled into the hole 21, the first ramp 112 first contacts the hole wall of the hole 21. The slope of the first ramp 112 is relatively small, so the assembly is relatively easy. When the assembly is in place, the second block 2 must overcome the interference force between the second ramp 113 and the groove wall 211 in order to detach from the first block 1. Since the slope of the second ramp 113 is relatively large, a larger force is required to break free from the interference between the second ramp 113 and the groove wall 211 compared to the assembly. Therefore, this structure increases the stability of the shaft and hole after assembly.
[0037] In this embodiment, the axial cross-sections of the outer surfaces of the first slope 112 and the second slope 113 are both straight lines. The first slope 112 is a ring structure, the second slope 113 is a ring structure, and the groove 211 is also a ring structure. That is, the boss 111 is a structure with the shaft 11 arranged continuously in the circumference.
[0038] like Figure 2 As shown, a connecting structure is also provided between the first slope 112 and the second slope 113. In practical applications, the axial section surface of the outer surface of the connecting structure can be designed as a straight line or a curve, such as an arc. It should be noted that the axial section surface of the outer surface of the connecting structure is the structure after being cut through the axis of shaft 11.
[0039] Furthermore, to facilitate smoother assembly and disassembly and reduce wear, the ends of shafts 11 are all chamfered, which facilitates assembly and prevents damage from sharp edges. Meanwhile, the connections between the first ramp 112, the second ramp 113, and the connecting structure are all smooth transition structures, which also facilitate assembly and protect the toy from damage.
[0040] When the boss 111 is assembled into the groove 211, the groove wall of the groove 211 fits tightly with the connecting structure.
[0041] In practical applications, the number of bosses 111 on shaft 11 can be flexibly designed according to different application scenarios. One boss 111 can be set in the length direction of shaft 11, or multiple bosses 111 can be set at intervals. The number of grooves 211 matches the number of bosses 111 to meet the requirements of firmness after assembly.
[0042] This utility model also provides a toy, including a toy assembly structure. For example, the toy is a toy car. The first building block 1 is a building block with an axle, and the second building block 2 is a wheel. By adopting a toy assembly structure, the toy car reduces the number of parts and improves the overall stability and durability of the toy.
[0043] Example 2:
[0044] Unlike Embodiment 1, the end of the first ramp 112 is directly connected to the end of the second ramp 113, and the axial cross-section of the boss 111 forms a triangular structure.
[0045] When the boss 111 is assembled into the groove 211, the groove wall of the groove 211 is clearance-fitted with the connecting structure.
[0046] In this embodiment, the first ramp 112 is part of the annular structure, and the second ramp 113 is part of the annular structure, that is, the entire boss 111 is a structure with a discontinuous arrangement around the shaft 11.
[0047] The working principle of this utility model is as follows:
[0048] When the shaft 11 is assembled into the hole 21, the first ramp 112 first contacts the hole wall of the hole 21. The slope of the first ramp 112 is small, which can guide the shaft 11 to gradually enter the hole 21, making the assembly easier.
[0049] When the assembly is in place, when the second block 2 and the first block 1 are disassembled, the interference force between the second slope 113 and the groove wall 211 must be overcome. Since the slope of the second slope 113 is relatively large, a larger force is required to break free from the interference between the second slope 113 and the groove wall 211 compared to the assembly. Therefore, under natural conditions, the structure in this utility model is not easy to detach, which increases the stability after the shaft hole is assembled.
