Detailed Description

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.

Example 1.

As shown in fig. 1-2, the dual-spindle fixing seat assembly described in this embodiment includes a seat body 1, a main shaft 2 and a secondary shaft 3 are disposed on the seat body 1 and staggered along the length direction of the seat body 1, the main shaft 2 is L-shaped, and has a first section 21 pivoted to the seat body 1 through a first pivot structure 4 and a second section 22 pivoted to an external component; the auxiliary shaft 3 is L-shaped and is provided with a third section 31 fixedly connected with the seat body 1 and a fourth section 32 pivoted with an external part; the length of the first section 21 extending from the surface of the seat body 1 is longer than the length of the third section 31 extending from the surface of the seat body 1; the axis of the second section 22 is parallel to the axis of the fourth section 32, and the circumferential surfaces of the second section 22 and the fourth section 32 are respectively provided with a flat surface 5, and the planes of the two flat surfaces 5 are parallel. In use, as shown in fig. 10, the seat body 1 is assembled on the roof of the vehicle body as required, the main shaft 2 is connected with the spring clips (not shown) in the main sun visor 100 through the flat surface 5 on the second section 22, and the auxiliary shaft 3 is connected with the spring clips in the auxiliary sun visor 200 through the flat surface 5 on the fourth section 32, so that the fixing seat assembly can support the normal function of the sun visor.

In this embodiment, the main shaft 2 and the auxiliary shaft 3 that are staggered along the length direction of the base 1 may be in the arrow direction as shown in fig. 10, that is, the main shaft 2 and the auxiliary shaft 3 are staggered along the advancing direction of the vehicle body at right and left intervals, it should be noted that the staggered arrangement of the main shaft 2 and the auxiliary shaft 3 is staggered along the advancing direction of the vehicle body, and by combining the structural design that the length of the first section 21 extending from the surface of the base 1 is greater than that of the third section 31 extending from the surface of the base 1, different using directions of the main sun visor and the auxiliary sun visor are compatible, so that the two are prevented from interfering or colliding with each other in different using directions, and meanwhile, the design of the lengths of the first section 21 and the third section 31 can ensure that the main sun visor 100 and the auxiliary sun visor 200 can abut against and be attached to the ceiling of the vehicle body when not being used, so as to minimize the storage space. In this embodiment, the difference between the length of the first section 21 extending from the surface of the base 1 and the length of the third section 31 extending from the surface of the base 1 is half of the sum of the average thicknesses of the main sun visor 100 and the auxiliary sun visor, so that the main sun visor 100 can be tightly attached to the auxiliary sun visor 200 when being stored, and the shaking of the sun visor caused by vibration during driving is reduced. In addition, the planes of the two flat surfaces 5 are parallel, so that the resistance of the spring clips is consistent at the initial position (the accommodating and jacking state) of the main sun visor 100 and the auxiliary sun visor 200, and the unstable state caused by vibration or jolt is avoided.

In some embodiments, as shown in fig. 3 and 5, the auxiliary shaft 3 is integrally formed with the base 1 for simplifying the manufacturing and assembling process. The integral molding eliminates the independent assembly step between the auxiliary shaft and the seat body, simplifies the manufacturing and assembly processes, saves time and labor cost and improves the production efficiency.

In some embodiments, as shown in fig. 7 and 8, the auxiliary shaft 3 is pivoted to the base 1 by a second pivoting structure 6, and the second pivoting structure 6 is identical to the first pivoting structure 4 for higher durability and strength. Like this, countershaft 3 can be with main shaft 2 the same, make alone and assemble with pedestal 1, avoided the restriction of disjunctor injection molding, this makes can adopt different materials and processing technology as required in the design of different motorcycle types, satisfies the demand of different pivot intensity, provides higher customization and flexibility, for example: the auxiliary shaft 3 can be injection-molded by embedding PA66-GF30 into a metal core, and the metal core is galvanized by Q235B and is formed by bending, forming, knurling, galvanizing and embedding injection molding, so that the structural strength of the auxiliary shaft is improved, and the requirements of the rotating shaft strength of different vehicle types are met.

In some embodiments, as shown in fig. 5 and 6, for a stable connection, the first pivot structure 4 includes a claw portion 41 integrally formed with the base 1 and a through hole 42 that is in close space communication with the claw portion 41 and is disposed through the base 1, and the first section 21 has a radially contracted portion 211 that passes through the through hole 42 to be matched with the claw portion 41, and a retaining portion 212 that passes over the claw portion 41 and has a radial width greater than that of the radially contracted portion 211. Thus, during assembly, only the first section 21 of the spindle 2 prepared in advance is required to be inserted into the through hole 42 in a high-temperature state of injection molding and demolding of the seat body 1, and as the radial width of the retaining portion 212 is larger than that of the radially-contracted portion 211, the claw portion 41 can be expanded along with the insertion of the first section 21, and at the moment, the retaining portion 212 passes over the claw portion 41, and the claw portion 41 loses the pressing force to restore and clamp the radially-contracted portion 211, so that the spindle 2 can be fixed, the capability of side blocking overturning can be provided for the main sunshade board 100, the connection stability is ensured, and meanwhile, the required functional requirement of the main sunshade board 100 is met, so that necessary support is provided for normal use of the sunshade board.

In some embodiments, as shown in fig. 4, in order to make the installed sun visor occupy a storage space, the base 1 has a mounting plane 11, the axis of the first section 21 is disposed at an angle to the mounting plane 11, and the axis of the third section 31 is perpendicular to the mounting plane 11. With the angle setting design, the turning axis (axis of the second section 22) of the main sun visor 100 can be positioned farther forward (away from the driving side position in the vehicle body), such design can allow a larger width sun visor to be accommodated in the same limited space, provide a larger range of sun shading function, and the mounting plane 11 provides a flat surface, so that the seat body 1 can be better attached to the vehicle body ceiling, ensuring that it will not loosen or move after being mounted.

Specifically, as shown in fig. 1 and 8, the base 1 is provided with a plurality of countersunk screw holes 12, and a protective cover 13 fastened to the surface of the base 1 and covering each countersunk screw hole 12. In the present embodiment, the countersunk screw hole 12 is provided to simplify the installation process, and the screw hole allows the head of the screw to be inserted into the hole, so that the screw does not protrude out of the surface of the seat 1 after installation; the design of the protective cover 13 also enables the countersunk head screw hole 12 to be in a protected state, so that the cover can be disassembled for screw installation or maintenance when needed, and the exposure of possibly existing sharp edges of the seat body 1 can be prevented.

In some embodiments, as shown in fig. 9, for light weight and improved strength, the spindle 2 is injection molded with PA66-GF30 and the metal core 23, and the metal core 23 is a hollow structure with a galvanized knurled outer surface. The PA66-GF30 has good strength and wear resistance, the hollow structure of the metal shaft core 23 can reduce the overall weight while maintaining the strength, the knurling treatment increases the compactness of the metal shaft core 23 and the PA66-GF30 which are integrally molded, the galvanization treatment can increase the durability and the service life of the metal shaft core 23, in addition, the hollow metal shaft core 23 provides more space, and the cosmetic mirror backlight power line on the sun visor can be more easily installed and arranged, so that the circuit arrangement is more concise and effective.

In some embodiments, as shown in fig. 2, in order to improve the structural strength of the base body, the side of the mounting plane 11 of the base body 1 is integrally formed with a reinforcing rib structure 7. The reinforcement structure 7 can effectively promote the compressive capacity of the seat body 1 under the action of pressure or load so as to more uniformly distribute the load and reduce the deformation or damage risk of the seat body 1 under the action of the pressure. In addition, in the embodiment, the seat body 1 can be injection molded by adopting PA66 and POM, and can also be subjected to die casting-polishing-plastic spraying processing by adopting ADC 12-grade aluminum alloy so as to improve the mounting and use strength of the seat body on the double sun visors and the anti-damage strength of the overhead explosion air bag.

The double-rotating-shaft fixing seat assembly provided by the embodiment meets the compatibility of different use directions of the main sun shield and the auxiliary sun shield through structural design, has the beneficial effects of good rotating performance, high durability and stable and reliable storage, greatly improves the use performance of the main sun shield and the auxiliary sun shield, and meets the requirements of high-end vehicle types on configuration and performance.
