Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle accessories, and specifically relates to a motorcycle frame. Background Art

[0002] The frame of a motorcycle is an important part of the vehicle structure. It not only supports all the main components of the motorcycle, such as the engine, fuel tank, seat, suspension system, and wheels, but also plays a key role in the vehicle's controllability, stability, and safety. Therefore, the design and material selection of the motorcycle frame directly affect the performance and durability of the motorcycle.

[0003] There are various types of motorcycle frames, such as double-beam frames, diamond frames, unitary frames, spine frames, and perimeter frames, etc. The most common one is the double-beam frame, which is composed of two parallel or nearly parallel main beams, usually welded with steel pipes. This kind of frame can provide good rigidity and stability and is suitable for most types of motorcycles.

[0004] For example, the patent with the publication number CN220054036U discloses a motorcycle frame, which includes a frame body. The frame body is composed of a head pipe, a cross-seat beam assembly, a front frame assembly, a rear frame assembly, a rear-wheel connecting frame, and a tail-seat connecting frame. The rear-wheel connecting frame is connected to the rear frame assembly through a connecting unit one, the tail-seat connecting frame is connected to the rear frame assembly through several studs, the front frame assembly is composed of two front pipes connected to the above-mentioned head pipe, the cross-seat beam assembly is composed of two cross beams, two connecting brackets one are arranged on the head pipe, the rear frame assembly is composed of two rear pipes, and both ends of the two rear pipes are respectively connected to the corresponding front pipes and cross beams mentioned above; it has the advantages of reducing the welding connection method and improving the structural stability.

[0005] However, the motorcycle frame in the above technology still has the following problems:

[0006] Although reducing the welding points makes some structures more stable, during the engine overhaul of the motorcycle, since the engine is inside the double beams of the frame, when installing and disassembling the engine, due to the limited space for placing the engine between the frame and the double beams, and the engine is generally heavy, it brings great inconvenience to the overhaul work of the motorcycle. Content of the Utility Model

[0007] Aiming at the deficiencies of the prior art, the utility model provides a motorcycle frame, for example: the engine can be quickly lowered from the double beams, and at the same time, it is convenient to align the engine with the gap between the double beams and complete the installation, making the overhaul work of the motorcycle more convenient.

[0008] To achieve the above object, the present utility model provides the following technical solution: A motorcycle frame includes a frame body, and a double beam is provided at the bottom of the frame body. A positioning plate is fixedly connected to the double beam, and a telescopic plate is slidably connected to the positioning plate. One end of the telescopic plate is connected to a baffle plate.

[0009] Further, there are two telescopic plates, and the two telescopic plates are symmetrically arranged. Both telescopic plates are fixedly connected to the baffle plate.

[0010] Further, two T-shaped chutes are opened on one side of the positioning plate close to the two telescopic plates. A sliding assembly is connected in each of the two T-shaped chutes. The two sliding assemblies are respectively connected to one end of the two telescopic plates away from the baffle plate and close to the positioning plate.

[0011] Further, one end of each of the two T-shaped chutes close to the baffle plate is a through setting. Four flipping blocks are fixedly connected to one end of the positioning plate close to the baffle plate. The four flipping blocks respectively correspond to both sides of the two T-shaped chutes.

[0012] Further, flipping grooves are opened on one side of adjacent two flipping blocks adjacent to each other. One side of a plurality of flipping grooves close to the positioning plate is communicated with the adjacent T-shaped chute. The sliding assembly is slidably connected to the adjacent T-shaped chute and flipping groove.

[0013] Further, the sliding assembly includes a connecting block and two symmetrically arranged flipping shafts. The connecting block is fixedly connected to one end of the telescopic plate away from the baffle plate and close to the positioning plate. The two flipping shafts are respectively fixedly connected to both sides of the connecting block. The connecting block is located between adjacent two flipping blocks and is slidably connected to the T-shaped chute. Both flipping shafts are located in the T-shaped chute and are slidably connected to the T-shaped chute. The two flipping shafts are respectively rotatably connected to the flipping grooves in the adjacent two flipping blocks.

[0014] Further, the baffle plate is an arc-shaped plate, and one end of the baffle plate away from the telescopic plate bends and extends inward.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] For this kind of motorcycle frame, by arranging a positioning plate and a telescopic plate on the double beam, with the assistance of the telescopic plate, the engine on the double beam of the motorcycle can be more easily drawn out from the double beam, and at the same time, it is convenient to quickly and accurately install the engine back into the double beam after maintenance, improving the maintenance efficiency of the motorcycle.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Please refer to Figure 1 - Figure 5 , a motorcycle frame, including a frame body 1, a double beam 2 is provided at the bottom of the frame body 1, a positioning plate 3 is fixedly connected to the double beam 2, a telescopic plate 4 is slidably connected to the positioning plate 3, and a baffle 5 is connected to one end of the telescopic plate 4.

[0025] As Figure 1 - Figure 5 shown, a motorcycle frame in the present invention is similar to the existing motorcycle frame structure. For example, a motorcycle frame disclosed in the patent with the publication number CN220054036U. The main improvement of the present invention is to facilitate the maintenance personnel to disassemble and install the motorcycle engine more quickly and improve the maintenance efficiency. As Figures 1 to 5 shown, when the motorcycle frame in the present invention is in use, the telescopic plate 4 is slid out from the positioning plate 3, and then the motorcycle engine to be installed on the double beam 2 is placed on the telescopic plate 4. Then, by pushing the baffle 5, the telescopic plate 4 and the engine are pushed inward to the double beam 2, so as to move the engine above the double beam 2 and inside the frame body 1, realizing the rapid installation of the motorcycle engine. Then, the engine is fixedly installed with the various fixing components inside the frame body 1, avoiding the inconvenience of manually lifting the engine for installation. At the same time, when disassembling the engine, the reverse operation can be performed, so as to more stably slide the engine out of the frame body 1, avoiding the scraping damage that may be caused by pulling and moving the heavy engine from the double beam 2.

[0026] AsFigure 1 - Figure 5 As shown in Figure 5 , there are two telescopic plates 4, and the two telescopic plates 4 are symmetrically arranged. Both of the two telescopic plates 4 are fixedly connected to the baffle 5. By providing two telescopic plates 4, support is provided on both sides of the positioning plate 3, so that after the engine is placed on the telescopic plates 4, the forces on both sides are more uniform, avoiding the engine from tilting. At the same time, there is a gap between the two telescopic plates 4, which facilitates fine-tuning the position of the engine on the two telescopic plates 4 through the middle gap when placing the engine, preventing the engine from tilting and being unable to slide into the inner side of the vehicle frame body 1.

[0027] As Figure 3 - Figure 5 As shown in Figure 5 , two T-shaped sliding grooves 301 are provided on one side of the positioning plate 3 close to the two telescopic plates 4. Sliding components are connected in both of the two T-shaped sliding grooves 301, and the two sliding components are respectively connected to one end of the two telescopic plates 4 away from the baffle 5 and close to the positioning plate 3. By the sliding of the sliding components in the T-shaped sliding grooves 301, the sliding of the telescopic plates 4 on the positioning plate 3 is more stable, and the situation of side-sliding and dislocation of the telescopic plates 4 will not occur.

[0028] As Figure 1 - Figure 5 As shown in Figure 5 , one end of both of the two T-shaped sliding grooves 301 close to the baffle 5 is provided in a penetrating manner. Four flipping blocks 6 are fixedly connected to one end of the positioning plate 3 close to the baffle 5, and the four flipping blocks 6 respectively correspond to both sides of the two T-shaped sliding grooves 301. By making the end of the T-shaped sliding groove 301 penetrate and communicate with the flipping block 6, when the sliding component moves to the position of the flipping block 6, it can be flipped by a certain angle, so that the telescopic plate 4 can be flipped downward at the end of the positioning plate 3, making it more convenient to move the engine onto the telescopic plate 4, and the baffle 5 blocks the telescopic plate 4.

[0029] As Figure 5 As shown in Figure 5 , flipping grooves 601 are provided on one side of adjacent two flipping blocks 6 adjacent to each other. One side of several flipping grooves 601 close to the positioning plate 3 is communicated with the adjacent T-shaped sliding groove 301, and the sliding component is slidably connected to the adjacent T-shaped sliding groove 301 and the flipping groove 601. After the sliding component moves to the penetrating position of the T-shaped sliding groove 301, it can move into the flipping groove 601 to realize the angular flipping of the telescopic plate 4.

[0030] As Figure 3 - Figure 5As shown, the sliding assembly includes a connecting block 7 and two symmetrically arranged turning shafts 8. The connecting block 7 is fixedly connected to the end of the telescopic plate 4 away from the baffle 5 and on the side close to the positioning plate 3. The two turning shafts 8 are respectively fixedly connected to both sides of the connecting block 7. The connecting block 7 is located between two adjacent turning blocks 6 and is slidably connected to the T-shaped chute 301. Both turning shafts 8 are located in the T-shaped chute 301 and are slidably connected to the T-shaped chute 301. The two turning shafts 8 are respectively rotatably connected to the turning grooves 601 in two adjacent turning blocks 6. Through the sliding of the connecting block 7 and the two turning shafts 8 in the T-shaped chute 301, the telescopic plate 4 can slide within a certain range on the positioning plate 3. At the same time, when the two turning shafts 8 move from the T-shaped chute 301 into the turning grooves 601, the telescopic plate 4 can rotate at a certain angle in the turning grooves 601 through the connecting block 7 and the two turning shafts 8, and the baffle 5 at the end abuts against the ground. At this time, the two telescopic plates 4 are at an inclined angle with the ground. At this time, the engine can be moved onto the telescopic plate 4. Subsequently, the engine is lifted upward through the baffle 5 and the telescopic plate 4. When it is at a position higher than the positioning plate 3, it is pushed inward towards the inside of the vehicle frame body 1, so as to smoothly push the telescopic plate 4 and the engine to slide above the double beam 2, completing the rapid installation of the engine.

[0031] As Figure 1 - Figure 4 shown, the baffle 5 is an arc-shaped plate, and the end of the baffle 5 away from the telescopic plate 4 bends inward and extends. The baffle 5 is designed to be arc-shaped and bend inward and extend. After the installation of the engine is completed, the top corners of the baffle 5 will not protrude beyond the scope of the vehicle frame body 1, thus avoiding scratching and hurting the users by the top corners of the baffle 5.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
