Technical Field

[0001] The utility model relates to the technical field of motorcycle accessories, in particular to an air intake device for a motorcycle. Background Art

[0002] The main function of a motorcycle's air intake device is to deliver clean, dry, sufficient and stable air to the engine to meet the engine's needs and prevent impurities, sand and dust in the air from entering the engine's combustion chamber and causing abnormal wear of the engine.

[0003] As restrictions on motorcycles in cities have been tightened, the number of motorcycle users has decreased significantly. Most of the existing motorcycle users are motorcycle enthusiasts, or use their motorcycles for competitions. Traditional motorcycle air intake devices are mostly integrated sealed boxes that use paper filters. Since the operating pressure of racing motorcycle engines is relatively high, the air intake device needs to operate efficiently, which increases the loss rate of the air intake device and requires frequent replacement of the air intake device, increasing the maintenance cost of the motorcycle.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-9 A motorcycle air intake device comprises: a rear bucket 1 and an air intake body 3, a support member 2 is installed at the rear end of the air intake body 3, the support member 2 is installed on the rear bucket 1, a retaining frame 5 is installed on the side of the support member 2 away from the air intake body 3, an air filter sponge 4 is sleeved on the retaining frame 5, and the air filter sponge 4 is located inside the rear bucket 1.

[0028] Among them, the rear bucket 1 includes a bucket body 11, the rear end of the bucket body 11 is concave to form a mud guard groove 12, the inner wall of the mud guard groove 12 is inclined, and a mounting hole 15 is opened at the bottom of the inner wall of the bucket body 11. The mounting hole 15 is installed on the motorcycle with bolts. The rear bucket 1 is mainly used as a supporting part of the air intake body 3. It is installed on the motorcycle through the mounting hole 15 to provide a suspension force for the air intake body 3 to prevent the air intake body 3 from swaying when the motorcycle is started. The mud guard groove 12 is used to block the mud and sand thrown when the motorcycle is started, and divert it out, thereby protecting the internal air filter sponge 4.

[0029] Among them, two protruding drainage cavities 13 are integrally provided at the bottom of the bucket body 11, and the inside of the two drainage cavities 13 are sealed with rubber plugs. When encountering a situation of wading and water ingress, the rubber plugs can be opened to drain water at the position of the bucket body 11 to prevent the incoming water from affecting the air intake.

[0030] Among them, a mounting groove 14 is opened in the front of the bucket body 11, and the support member 2 is engaged in the inner wall of the mounting groove 14. A mounting hole is opened on the edge of the bucket body 11 near the mounting groove 14. The mounting groove 14 provides a snap-fitting space for the installation of the support member 2 and the rear bucket 1, thereby increasing the stability of the support member 2 after installation. At the same time, the air filter sponge 4 can be first connected with the support member 2, and then the air filter sponge 4 can be inserted into the bucket body 11 through the mounting groove 14, so that the support member 2 and the rear bucket 1 are installed, thereby avoiding the situation where the air filter sponge 4 is installed later and causes a gap at the installation location.

[0031] The air filter sponge 4 is made of polyurethane, and the air filter sponge 4 can effectively filter out sand and dust in the air, so that the motorcycle can travel on the road in harsh environment.

[0032] Among them, the retaining frame 5 includes a frame 51, and the frame 51 is formed by welding of stainless steel wire as a whole. A welding ring 52 is welded at the interactive midpoint of the frame 51. A guide tube 53 is integrally provided in the middle of the welding ring 52. A long screw 6 is inserted into the inside of the guide tube 53, and the end of the long screw 6 is installed with the support member 2. The retaining frame 5 is used as the skeleton of the air filter sponge 4, and the air filter sponge 4 is fully opened and covered at the air intake of the motorcycle, so that the air entering the air intake device is filtered.

[0033] Among them, the support member 2 includes a ring piece 21, a middle frame 22 is integrally formed in the middle of the ring piece 21, a hoop groove 23 is opened on one side of the ring piece 21, the front end of the retaining frame 5 is hooped inside the hoop groove 23, and an outer piece 24 is integrally formed on the outer edge of the ring piece 21. The outer piece 24 is installed with the front end of the rear bucket 1 by bolts. The whole support member 2 is made of aluminum alloy CNC processing. By setting the support member 2 as the connecting body of each component, each component can be removed at one time, thereby improving the disassembly and maintenance efficiency of the intake device.

[0034] Among them, the air intake main body 3 includes an air intake box 31, and the whole air intake box 31 is integrally formed by 3D printing. The installation position of the tail end of the air intake box 31 and the support member 2 is coated with sealant. A sleeve hole 32 is opened at the front end of the air intake box 31, and an air guide rubber tube is arranged inside the air intake box 31. The air guide rubber tube is away from the air intake box 31 through the sleeve hole 32 and is connected to the high-pressure common rail throttle of the engine electronic fuel injection system. The front end of the air intake main body 3 is connected to the engine in a probe-type manner. The air intake main body 3 is integrally formed by 3D printing, polished and annealed in a drying oven for 45 minutes to make the material's water absorption and structural density uniform and increase strength. The inner and outer three-layer setting is adopted during printing, and a honeycomb support interval is adopted in the middle to achieve a full waterproof effect, thereby improving the sealing effect of the air intake device.

[0035] Working principle: when installing the air intake device, first use bolts to install the rear bucket 1 on the motorcycle, then install the air intake body 3 on the front side of the support 2, and then cover the air filter sponge 4 on the retaining frame 5, and then use long screws 6 to connect the retaining frame 5 to the air filter sponge 4 and install it on the rear side of the support 2, insert the air intake body 3 on the engine, and install it with the structure on the engine, and finally install the installed support 2 on the front end of the rear bucket 1.
