Description

TECHNICAL FIELD

[0001] The present application relates to the field of motorcycle technology, in particular to a motorcycle. BACKGROUND

[0002] With the transformation of fuel motorcycles to electric motorcycles, electric motorcycles are becoming more and more popular. Compared with fuel motorcycles, electric motorcycles no longer need fuel tanks, but instead use batteries to provide energy for motorcycles. In the prior art, once the battery is installed, it is difficult to disassemble. Most batteries are fixedly installed on the electric motorcycle. When the battery needs to be disassembled, the structure fixing the battery needs to be damaged. Therefore, the charging of the battery is basically in the state of the whole electric motorcycle. However, in actual application, it is found that the charging of the electric motorcycle is limited by the parking position of the motorcycle. For some newly established communities, the charging convenience of electric motorcycles has been taken into account, and the parking area for electric motorcycles is demarcated, and charging structures are set up in the parking area to facilitate the charging of electric motorcycles parked in the parking area. However, there are still many old communities and old buildings without dedicated electric motorcycle charging areas, resulting in many people having to move the entire electric motorcycle to the door for charging. However, this method increases the difficulty of moving the electric motorcycle due to the weight of the electric motorcycle itself and the housing conditions, making the charging of the electric motorcycle very troublesome.

[0003] In addition, in the transformation of fuel motorcycles to electric motorcycles, there are schemes that directly design the original fuel tank position as the battery fixing installation position. For example, a high-performance electric motorcycle chassis structure with patent publication number CN211167255U. In this patent technology, the battery is placed in the fuel tank position of the fuel motorcycle. This method reasonably utilizes the space of the canceled fuel tank position. However, because the battery structure is square, large in size and heavy in weight, it is placed on the mounting beam (i.e. the supporting beam) at the bottom of the frame of CN211167255U. There is no protective pipe on the side of the battery near the bottom of the frame, so that once the electric motorcycle tips over, the battery is easily impacted with the ground. When the battery is subjected to excessive impact, it may cause safety hazards.

[0004] In addition, because the battery on the electric motorcycle is heavy, the overall weight of the electric motorcycle is heavier. Under the same road conditions and driving conditions, the vibration of the frame of the electric motorcycle is more intense, affecting the strength of the frame of the electric motorcycle. SUMMARY

[0017] The principles and advantages of the present application are as follows:

[0018] 1、The battery on the motorcycle is placed in the battery accommodating box, and after the lock hook and the lock ring of the battery fixing assembly are buckled tightly, the transverse section of the pressing plate presses the battery in the battery accommodating box, so that the battery is limited by the battery accommodating box from all around and is pressed tightly from the top by the battery fixing assembly, so that the battery will not loosen during driving of the motorcycle. When the motorcycle needs to be charged, the connection relationship between the battery and other electrical elements is released, and the rotating handle is rotated, so that the rotating handle is close to the lock ring, the rotation of the rotating handle releases the buckling state of the lock ring and the lock hook, then the lock hook and the pressing plate with the lock ring are taken off from the through slot of the mounting plate, then the plug inserted on the battery is taken off, finally the battery pack with the handle is lifted up, and the battery can be taken out, which is convenient for transferring the battery to a suitable position for charging. Compared with the prior art of transferring the entire motorcycle, the present scheme only needs to simply and quickly release the connection between the lock hook and the lock ring of the battery fixing assembly and the connection between the lock hook and the mounting plate, so that the battery can be disassembled, so as to facilitate charging of the battery, and the charging difficulty of the motorcycle is greatly reduced.

[0019] 2、When the battery on the motorcycle is disassembled, only the pressing plate and the lock hook need to be operated, and the pressing plate and the lock hook are movably connected to the through slot of the mounting plate, so that the disassembly and assembly of the entire battery do not need to use auxiliary tools, and the operation of disassembly and assembly of the battery is simple and convenient.

[0020] 3、The U-shaped structure of the rotating handle cooperates with the lock column with the lock hole, so that the rotating handle is not only a driving structure for driving the lock ring to rotate and buckle tightly, but also can hang a padlock after the lock buckle is connected with the lock hook, so as to realize the anti-theft function of the battery.

[0021] 4、The design of the buckle ring and the connecting leg of the lock ring makes it possible to adjust the position of the lock ring by screwing the connecting leg when the relative positions and sizes of the two mounting plates on the motorcycle are deviated in size after long-term use of the same motorcycle or different motorcycles, so that the lock ring can always be buckled tightly with the lock hook, and the pressing force of the pressing plate on the battery fixing assembly on the battery can be ensured; the present scheme reduces the manufacturing process requirements of the mounting plate and the battery accommodating box, and also meets the needs of users to adjust the position of the lock ring after the relative positions of the two mounting plates change slightly after long-term use of the motorcycle, so that the battery fixing assembly can still be adjusted to the state of pressing the battery with the pressing plate after long-term use of the motorcycle, and the installation stability of the battery can be ensured even after multiple disassembly and assembly and long-term use on the motorcycle.

[0022] 5、In the present application, the battery accommodating box can be shielded by the decoration assembly, so as to ensure the appearance beauty of the motorcycle, and the first barrier for taking out the battery is formed by the cover of the decoration assembly.

[0023] 6、The motorcycle of the present application is equipped with a 220V charging seat for charging gun, a household 220V charging seat and a socket capable of connecting to the household 220V power supply system on the battery, which facilitates the charging of the motorcycle using household electricity and also facilitates the charging of the motorcycle on the charging pile, ensuring that the motorcycle can be charged anywhere with power supply, greatly improving the charging convenience of the invented motorcycle.

[0024] 7、The present application sets an upper cross beam with an elliptical cross section on the frame, which has a larger cross-sectional area under the condition that the short axis of the elliptical upper cross beam is basically the same as the diameter of the circular tube, so that the strength of the upper cross beam is higher, and meanwhile, one end of the upper cross beam is connected to the head tube, and the other end is connected to the end of the supporting beam, and the end of the supporting beam is connected to the shock absorber mounting seat, and the shock absorber is mounted on the shock absorber mounting seat, when the head tube bears the impact from the front wheel, the vibration generated by the frame can be quickly transmitted to the shock absorber mounted at the end of the supporting beam through the upper cross beam, and the vibration can also be quickly transmitted to other parts of the frame from the lower cross beam, so that the vibration caused by the impact is dispersed to various positions of the frame, and the energy caused by the vibration can be quickly absorbed by the shock absorber, greatly improving the shock absorption performance of the motorcycle.

[0025] 8、The setting of the elliptical upper cross beam of the present application makes the other tubes connected to the upper cross beam in the vertical direction have a larger connection contact area, which on the one hand is conducive to increasing the connection strength of the upper cross beam and the other tubes connected in the vertical direction, and on the other hand, based on the larger contact area with other tubes, the vibration generated by the frame is also easier to be transmitted to other parts of the frame, further improving the strength and shock absorption performance of the frame.

[0026] 9、The left and right supports with upper and lower cross beams of the present application are located on both sides of the battery, so that the upper and lower cross beams simultaneously protect the side of the battery, ensuring that the battery will not be directly impacted after the motorcycle is overturned, reducing the safety hazard caused by the vehicle overturning; in addition, the bottom support tube and the rear side support tube are fixedly connected between the left support and the right support, which on the one hand forms direct support for the battery containing box, and on the other hand also forms protection for the bottom and rear side of the battery; in addition, the rear side support tube simultaneously supports the rear side connecting plate and the rear side connecting piece, improving the connection strength and support strength of the rear side support tube to the battery containing box.

[0027] 10、In the present application, the number of motor suspension mounting pieces is multiple, and different motor suspension mounting pieces are connected to the motor at different heights, plus the setting of the diagonally outward inclined motor suspension mounting piece, so that after the motor is installed on the frame, the front, rear, left, right, upper and lower positions of the motor are all limited, ensuring the stability of the motor installation and reducing the generation of vibration.

[0028] 11、The battery accommodating box is arranged at the left upper portion of the frame, the motor is arranged at the right lower portion of the frame, and the battery accommodating box is arranged obliquely, so that the space directly below the battery accommodating box is occupied by the controller installed on the controller installation frame, the controller and the battery generate a large amount of heat, the upper and lower positions of the battery accommodating box and the controller are arranged, so that the battery and the controller can directly contact the airflow generated in the running process, the rationality of space utilization is considered, and the battery and the controller can be better cooled; no obstruction is arranged at the rear of the frame, so that the motor can also be quickly cooled during the driving of the motorcycle, the stability of long-term work of the motor, the battery and the controller is ensured, and the service life of the motor, the battery and the controller is improved. Meanwhile, the obliquely arranged battery accommodating box guides the wind flowing through the frame, avoids that high-speed airflow impacts the complex space below the motorcycle seat, is beneficial to reducing wind resistance and wind noise, and is beneficial to heat dissipation.

[0044] The basic implementation examples are as follows: Figures 1 to 13 As shown.

[0045] Combination Figures 1 to 5 A motorcycle includes a frame and a battery housing 10, a motor 40, a controller 50, and a converter 60 for charging a battery 70 mounted on the frame. The battery housing 10 has an opening at the top and is used to install the battery 70.

[0046] The frame is provided with a household 220V charging seat 20 and a 220V charging seat 30 for a charging gun. The battery 70 is provided with a socket, and a plug is connected to the socket. The plug integrates a connecting line for connecting the battery 70 with other electrical components of the electric motorcycle. The socket is located at the top of the battery 70 and can be connected to a household 220V power supply system. The frame is fixed with a decorative assembly for shielding the outside of the frame. The decorative assembly includes a left decorative part, a right decorative part, and a cover 90. The left and right decorative parts are located on both sides of the cover 90. The cover 90 is rotatably connected to the frame and located above the battery 70. The rotation center of the cover 90 is located at one end close to the motorcycle head. The cover 90 forms the upper surface of the motorcycle. A cover 90 lock is arranged between the free end of the cover 90 and the frame. In this embodiment, the cover 90 lock can be unlocked by rotating a key, and the unlocked cover 90 can be rotated and opened to the state shown in FIG. 2.

[0047] In combination Figures 6 to 9 The frame includes a frame and a battery containing box 10 mounted on the frame. The frame includes a head pipe 1, a left support 2, a right support 3, and a rear support 4. The left and right supports 2 and 3 are located between the head pipe 1 and the rear support 4 and are symmetrical about the head pipe 1. The left and right supports 2 and 3 are fixedly welded with the head pipe 1 and the rear support 4. Decorative plates are fixed on the left and right supports 2 and 3. The household 220V charging seat 20 and the 220V charging seat 30 for the charging gun are mounted on the two decorative plates, respectively. The decorative plates are made of aluminum alloy. The battery containing box 10 is used for containing the battery 70. The top of the battery containing box 10 is open. Heat dissipation holes 101 are formed on the front side and the left and right sides of the battery containing box 10. The battery containing box 10 is located in the space enclosed by the head pipe 1, the left support 2, and the right support 3. The front, rear, left, and right sides of the battery containing box 10 are surrounded by the frame, thereby protecting the battery 70 in the battery containing box 10 and ensuring that the battery 70 will not be directly impacted when the motorcycle is overturned, thereby reducing the safety hazard caused by the motorcycle overturning.

[0048] The left and right supports 2 and 3 each include an upper cross beam 22, a lower cross beam 23, and a supporting beam 21. The upper and lower cross beams 22 and 23 are bent at one end welded with the head pipe 1. The bent sections of the upper and lower cross beams 22 and 23 are close to each other and form a V shape. The upper cross beam 22 is located on the left and right sides of the battery containing box 10. The cross section of the upper cross beam 22 is oval, i.e., the upper cross beam 22 is an oval pipe. The long axis of the oval cross section of the upper cross beam 22 is in the vertical direction, and the short axis of the oval cross section of the upper cross beam 22 is in the horizontal direction. The lower cross beam 23 and the supporting beam 21 are both circular pipes.

[0049] The right end of the upper cross beam 22 connected with the supporting beam 21 is processed with a deformation groove 221 penetrating the short shaft direction of the upper cross beam 22. Through the deformation groove 221, the length of the upper cross beam 22 in the long axis direction can be shortened by the deformation groove 221, which facilitates the lap joint and fixation of the upper cross beam 22 and the supporting beam 21 and improves the connection stability of the two. In addition, the setting of the deformation groove 221 enables the impact energy borne by the upper cross beam 22 to be released on the deformation groove 221.

[0050] The upper cross beam 22 and the lower cross beam 23 are welded with a reinforcing piece one 24 and a reinforcing piece two 25. The interval of the reinforcing piece one 24 and the reinforcing piece two 25 at the end connected with the upper cross beam 22 is smaller than the interval at the end connected with the lower cross beam 23.

[0051] The supporting beam 21 adopts an integral structure. The projection of the supporting beam 21 to the side of the motorcycle is in a U shape. The right end of the supporting beam 21 is bent to form an L-shaped connecting section 211. The two L-shaped connecting sections 211 are close to each other. The L-shaped connecting sections 211 of the left and right frames are combined in a U shape. The upper cross beam 22 is welded with the corresponding L-shaped connecting section 211. The two L-shaped connecting sections 211 are welded with a shock absorber mounting seat 8. The shock absorber mounting seat 8 is used to install a shock absorber.

[0052] The setting of the upper cross beam 22, the lower cross beam 23, the supporting beam 21 and the shock absorber mounting seat makes the overall strength of the frame higher. At the same time, the vibration caused by the impact on the front wheel of the motorcycle during the driving of the motorcycle can be quickly transmitted along the upper cross beam 22 to the shock absorber installed at the end of the supporting beam 21. The vibration is quickly transmitted from the lower cross beam 23 to the supporting beam 21, the reinforcing piece one 24 and the reinforcing piece two 25 and other parts, which greatly improves the shock absorption performance of the frame. At the same time, the setting of the elliptical tube of the upper cross beam 22 makes the contact length with other parts lapped with the upper cross beam 22 longer. The vibration generated by the upper cross beam 22 can also be quickly transmitted along the parts connected therewith, such as the reinforcing piece one 24 and the reinforcing piece two 25, to other parts of the frame, so that the entire frame can bear the vibration more evenly, further improving the shock absorption performance of the frame.

[0053] In combination Figures 6 to 11 The left support 2 and the right support 3 are fixedly connected with a bottom support pipe 5 and a rear side support pipe 6. The battery containing box 10 is placed above the bottom support pipe 5 and is fixedly connected with the bottom support pipe 5. The rear side support pipe 6 is located at the rear side of the battery containing box 10 and is fixedly connected with the rear side of the battery containing box 10.

[0054] Specifically, the bottom of the battery accommodating box 10 is bent with a bottom connecting plate 102 at the hole wall edge opposite to the heat dissipation hole 101, and the bottom connecting plate 102 is fixedly connected with the bottom supporting pipe 5 through the bottom connecting piece 51 arranged therebetween; the bottom connecting piece 51 is in a U shape, the belly of the bottom connecting piece 51 is attached to the bottom connecting plate 102, and one wing of the bottom connecting piece 51 is attached to the lower surface of the bottom of the battery accommodating box 10, so that the bottom supporting pipe 5 has sufficient supporting strength for the bottom of the battery accommodating box 10, and meanwhile, the arrangement of the bottom connecting plate 102 is equivalent to a fin on the battery accommodating box 10, which is beneficial to improve the heat dissipation capacity of the battery accommodating box 10.

[0055] The rear side of the battery accommodating box 10 is welded with a rear side connecting plate 103, the rear side connecting plate 103 is fixedly connected with the rear side supporting pipe 6 through the rear side connecting piece 61, and the rear side connecting plate 103 and the rear side connecting piece 61 are both machined with an arc-shaped contact bottom surface, the rear side connecting plate 103 and the rear side connecting piece 61 are erected above the rear side supporting pipe 6 through the arc-shaped contact bottom surface, and the arc-shaped contact bottom surface is in a U shape along the projection of the cross section of the rear side supporting pipe 6. The rear side supporting pipe 6 supports the rear side connecting plate 103 and the rear side connecting piece 61 at the same time, so as to improve the connecting strength and supporting strength of the rear side supporting pipe 6 for the battery accommodating box 10; in addition, the arc-shaped contact bottom surface is in a U shape along the projection of the cross section of the rear side supporting pipe 6, so that the rear side supporting pipe 6 forms limiting in the front-rear direction and the up-down height space for the battery accommodating box 10 on the basis of ensuring the supporting strength of the battery accommodating box 10, thereby ensuring the stability of the battery accommodating box 10 during the formation of the motorcycle.

[0056] The rear side supporting pipe 6 is fixedly connected between the lower cross beams 23 of the left support 2 and the right support 3, and the two lower cross beams 23 are welded with end supporting pipes 7 at the right ends, the end supporting pipes 7 extend to the outer side of the lower cross beams 23 and are welded with the corresponding supporting beams 21 at both ends.

[0057] The bottom supporting pipe 5 is welded at the left side of the two supporting beams 21. The left end of the supporting beam 21 is welded with the lower cross beam 23.

Among the four motor suspension mounts 212, three are welded to the bottom of the frame, and the remaining one motor suspension mount 212 is installed at a position higher than the center axis of the motor 40 of the frame, and the remaining one motor suspension mount 212 is a reinforcing connector, which includes a fixed lug and an adjusting connector 2121, the fixed lug is welded to the front end standing section of the U-shaped support beam 21 near the head tube 1, and the adjusting connector 2121 is provided with mounting holes and a waist-shaped hole 2122, and the adjusting connector 2121 is fixedly connected to the motor 40 and the fixed lug through the mounting holes and the waist-shaped hole 2122 by screws or bolts. The three motor suspension mounts 212 welded to the bottom of the frame define the installation plane of the motor 40, and the motor suspension mount 212 with the adjusting connector 2121 facilitates the fixed connection of the other three motor suspension mounts 212 after the motor 40 is placed on the frame. After the three motor suspension mounts 212 at the bottom of the frame are fixedly connected to the motor 40, the adjusting connector 2121 is rotated to be fixedly connected to the motor 40. The multiple motor suspension mounts 212 at different heights make the installation of the motor 40 simple and stable, and the waist-shaped hole 2122 of the adjusting connector 2121 can reduce the process requirements of the motor 40 installation and the production cost of the motorcycle.
