Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts technology, and in particular to aircraft handlebars and tricycles. Background Technology

[0002] With the development of the recreational tricycle industry, the design of tricycle handlebars has also undergone significant changes. The application of aircraft handlebar design elements to electric tricycle handlebars has greatly improved the riding experience. However, while adopting aircraft handlebars enhances the product's appearance and provides riders with a better riding experience, it also brings certain drawbacks to electric tricycle manufacturers.

[0003] Currently, there are two main types of aircraft handlebar installation. One type is where the aircraft handlebar is directly integrated with the vehicle. This type of aircraft handlebar is not easy to disassemble and will result in a higher overall vehicle height at the time of manufacture, requiring a taller packaging box and filler, which increases packaging and transportation costs. Another option is to use detachable handlebars. Detachable handlebars mainly come in two types. One type is a split design with an opening at the top, allowing for installation and removal from the top. However, this requires disassembling the dashboard first, then reinstalling the handlebars, a process involving wiring and dashboard manipulation, making it relatively complex. The other type uses an integrated design, but the installation method with the vehicle is altered. The handlebar's fixed axle connects to the vehicle's stem axle, and openings are provided on the vehicle body corresponding to the connection points. Installation and removal only require disassembling the fixed door at the opening on the vehicle body, then installing and removing the fixed axle and stem axle. However, since different vehicle models have different body shells, using the same handlebar requires designing suitable openings for different body shells, resulting in low versatility. Therefore, there is an urgent need for a new type of handlebar and tricycle to solve these technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide an airplane handle and a tricycle to solve the problems existing in the prior art, making the airplane handle more versatile and easy to install and disassemble.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides an aircraft handle, including an aircraft handle body, an aircraft handle shell, and a fixed shaft. The aircraft handle body is fixedly connected to the fixed shaft. The aircraft handle shell is wrapped around the outside of the aircraft handle body and fixedly connected to the aircraft handle body. An operating hole is provided on the aircraft handle shell. The fixed shaft is detachably connected to the handlebar shaft of a vehicle through a fastener. The fastener can be installed and removed through the operating hole.

[0007] In some embodiments, the aircraft fuselage includes a main shell and a fixed door. The main shell is wrapped around the outside of the aircraft fuselage body and fixedly connected to the aircraft fuselage body. An operating hole is provided on the main shell, and the fixed door is detachably connected to the operating hole.

[0008] In some embodiments, a sleeve is also included, which is sleeved outside the fixed shaft, and the fixed shaft is sleeved outside the handlebar shaft, and the fixing member can fix the sleeve, the fixed shaft and the handlebar shaft.

[0009] In some embodiments, the fastener is a bolt, and the sleeve, the fixed shaft, and the handlebar shaft are all provided with bolt holes for the bolt to pass through. The bolt can pass through the sleeve, the fixed shaft, and the handlebar shaft and be locked by a nut.

[0010] In some embodiments, the fixed door is snapped into the main housing, a slot is provided on the main housing around the operating hole, and a buckle is provided on the edge of the fixed door, the buckle being able to snap into the slot.

[0011] In some embodiments, the main housing and the fixed door are connected by screws. Both the main housing and the fixed door are provided with threaded holes. The screws pass through the threaded holes on the fixed door and the threaded holes on the main housing in sequence to connect the main housing and the fixed door.

[0012] In some embodiments, the main housing includes a first housing and a second housing, which are detachably connected. The first housing is located above the second housing and is used to mount an instrument panel. The second housing can accommodate the fixed shaft.

[0013] In some embodiments, a reinforcing plate and a reinforcing pad are also included. The reinforcing plate is semi-cylindrical, and the reinforcing pad is cylindrical. The reinforcing plate is disposed between the fixed shaft and the sleeve. The reinforcing plate has a receiving hole. The two ends of the reinforcing pad are respectively located in the bolt hole of the sleeve and the receiving hole of the reinforcing plate. The reinforcing pad is used to support the bolt hole of the sleeve and the receiving hole of the reinforcing plate.

[0014] In some embodiments, the inner wall of the sleeve is provided with a limiting groove, and the circumferential end of the reinforcing piece can be engaged in the limiting groove.

[0015] This utility model also provides a tricycle, including a handlebar axle and an airplane handle as described above.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] This utility model provides an aircraft handlebar with an outer shell that wraps around and is fixedly connected to the main body of the aircraft handlebar. An operating hole is provided on the outer shell, and the fixed shaft is detachably connected to the vehicle's handlebar shaft via a fastener. The fastener can be installed and removed through the operating hole. When the aircraft handlebar needs to be removed from the vehicle for transport, a disassembly tool is inserted into the operating hole to remove the fastener. After removal, the fixed shaft and handlebar shaft are no longer connected, and the aircraft handlebar can be directly removed from the vehicle. When the aircraft handlebar needs to be installed on the vehicle, the fastener is installed through the operating hole, achieving a fixed connection between the fixed shaft and handlebar shaft. The aircraft handlebar can be disassembled from the vehicle, reducing packaging and transportation costs, and is easy to assemble and disassemble. Furthermore, by creating a hole in the outer shell of the aircraft handlebar itself, and using the operating hole for assembly and disassembly, holes in the vehicle body are avoided. One aircraft handlebar can be used on various vehicle models, improving its versatility. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this utility model is to provide an airplane handle and a tricycle to solve the problems existing in the prior art, making the airplane handle more versatile and easy to install and disassemble.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 1-3 As shown, this utility model provides an airplane handlebar, including an airplane handlebar body, an airplane handlebar housing 1, and a fixed shaft 3. The airplane handlebar body is fixedly connected to the fixed shaft 3. The airplane handlebar housing 1 is wrapped around the airplane handlebar body and fixedly connected to it. An operating hole is provided on the airplane handlebar housing 1. The fixed shaft 3 is detachably connected to the vehicle's handlebar shaft 2 via a fastener, and the fastener can be installed and removed through the operating hole. When the airplane handlebar needs to be removed from the vehicle for transportation, a disassembly tool is inserted into the operating hole to disassemble the fastener. After the fastener is disassembled, the fixed shaft 3 is no longer connected to the handlebar shaft 2, and the airplane handlebar can be directly removed from the vehicle. When the airplane handlebar needs to be installed on the vehicle, the fastener is installed through the operating hole, achieving a fixed connection between the fixed shaft 3 and the handlebar shaft 2. The airplane handlebar can be disassembled relative to the vehicle, reducing packaging and transportation costs, and is easy to assemble and disassemble. Furthermore, by making holes in the outer shell of the aircraft handlebar itself and using the operating holes on the outer shell 1 for disassembly and assembly, the need to make holes in the vehicle body is avoided. One type of aircraft handlebar can be used in vehicles of various models, thus improving the versatility of the aircraft handlebar.

[0028] In some embodiments, the aircraft handlebar housing 1 includes a main housing 11 and a fixed door 12. The main housing 11 covers the outside of the aircraft handlebar body and is fixedly connected to the aircraft handlebar body. An operating hole is provided on the main housing 11, and the fixed door 12 is detachably connected to the operating hole. The fixed door 12 can be detachably covered outside the operating hole, effectively preventing rainwater, dust, mud, and other debris from entering the aircraft handlebar when not being disassembled. For example, when the vehicle is driving in rainy weather or on muddy roads, the fixed door 12 can prevent the operating hole from becoming a water inlet channel, avoiding rust on the fasteners or corrosion of the main components, and extending the service life of the aircraft handlebar. After the fixed door 12 is fitted and connected to the main housing 11, it can keep the surface of the aircraft handlebar housing 1 flat, avoiding appearance defects caused by exposed operating holes. For example, the fixed door 12 uses the same material and color as the main housing 11, and when closed, it almost blends into the housing, enhancing the overall aesthetics and design of the vehicle.

[0029] In some embodiments, the aircraft handlebar also includes a sleeve 5, which is sleeved outside the fixed shaft 3, and the fixed shaft 3 is sleeved outside the handlebar shaft 2. A fastener can fix the sleeve 5, the fixed shaft 3, and the handlebar shaft 2, and the three components are coaxially arranged. The combined rigidity of the three-layer nested structure of the sleeve 5, the fixed shaft 3, and the handlebar shaft 2 is greater than that of a single fixed shaft 3 connection, effectively resisting the torque and bending force experienced by the aircraft handlebar. For example, in the event of a vehicle collision, the cooperation between the sleeve 5 and the fixed shaft 3 can absorb some of the impact force, reduce the probability of handlebar deformation, protect core components, and the sleeve 5 plays a certain reinforcing role.

[0030] In some embodiments, the fastener is a bolt 4. The sleeve 5, the fixed shaft 3, and the handlebar shaft 2 all have bolt holes for the bolt 4 to pass through. The bolt 4 can pass through the sleeve 5, the fixed shaft 3, and the handlebar shaft 2 and is locked in place by a nut. After the bolt 4 passes through the bolt holes in the sleeve 5, the fixed shaft 3, and the handlebar shaft 2, the axial preload is generated by tightening the nut, tightly fitting the three-layer structure together. This rigid connection effectively resists vibrations, torques, and impacts during riding, preventing the handlebars from loosening. For example, vibrations caused by road bumps during high-speed riding are offset by the preload of the bolt 4, ensuring long-term stability of the connection. The length of the bolt 4 can be selected based on the total thickness of the sleeve 5, the fixed shaft 3, and the handlebar shaft 2.

[0031] In some embodiments, the fixed door 12 is snapped into the main housing 11. A slot 113 is provided on the main housing 11 around the operating hole, and a buckle is provided on the edge of the fixed door 12, which can engage with the slot 113. The fixed door 12 is secured by the snap-fit ​​structure of the buckle and the slot 113, allowing for assembly and disassembly without the need for screwdrivers, wrenches, or other tools. The slot 113 may have a barb or bevel structure inside, which, when engaged, creates a locking effect, preventing the fixed door 12 from accidentally falling off due to vehicle vibration. The fitting gap between the snap-fit ​​fixed door 12 and the main housing 11 can be controlled within a small range, resulting in almost no visible seam and enhancing the overall quality of the aircraft handle.

[0032] In some embodiments, the main housing 11 and the fixed door 12 are connected by screws. Both the main housing 11 and the fixed door 12 have threaded holes. The screws pass through the threaded holes on the fixed door 12 and the main housing 11 in sequence to connect the main housing 11 and the fixed door 12. After the screws pass through the threaded holes of the fixed door 12 and the main housing 11, they are tightened to form a rigid mechanical connection, which can effectively resist vibration, impact, and torsional forces. A rubber sealing ring can be installed between the fixed door 12 and the main housing 11 during screw connection. After the screws are tightened, the sealing ring is deformed by pressure, filling the gaps. The installation of the sealing ring can effectively prevent rainwater and mud from entering, protecting the internal fasteners from rusting.

[0033] In some embodiments, the main housing 11 includes a first housing 111 and a second housing 112, which are detachably connected. The first housing 111 is located above the second housing 112 and is used to mount the instrument panel. The second housing 112 can accommodate the fixing shaft 3. The first housing 111 is specifically used to mount the instrument panel (such as a speedometer or battery display), while the second housing 112 is responsible for accommodating the fixing shaft 3, thus separating the functions of control display and mechanical connection. For example, the instrument panel's circuit wiring can be independently laid out within the first housing 111 to avoid interference with the mechanical structure of the second housing 112 and improve assembly efficiency. The first housing 111 and the second housing 112 are detachably connected (e.g., by snap-fit ​​or screw connection). During maintenance, the first housing 111 can be disassembled separately to inspect the instrument panel, or the second housing 112 can be disassembled to maintain the fixing shaft 3. For example, if the instrument panel malfunctions, it is not necessary to disassemble the entire aircraft; only the first housing 111 needs to be removed to replace the display screen. The first shell 111 can be designed in various specifications (such as round instruments and rectangular displays) according to the dashboard size of different car models, while the fixed shaft 3 of the second shell 112 remains universal. For example, when a car manufacturer launches a new model, it only needs to replace the mold of the first shell 111, and the second shell 112 can be reused, reducing modification costs.

[0034] In some embodiments, the aircraft handle also includes a reinforcing plate 6 and a reinforcing pad. The reinforcing plate 6 is semi-cylindrical, and the reinforcing pad is cylindrical. The reinforcing plate 6 is disposed between the fixed shaft 3 and the sleeve 5, and has a receiving hole. The two ends of the reinforcing pad are respectively located in the bolt 4 hole of the sleeve 5 and the receiving hole of the reinforcing plate 6. The reinforcing pad is used to support the bolt 4 hole of the sleeve 5 and the receiving hole of the reinforcing plate 6. The semi-cylindrical shape of the reinforcing plate 6 fits between the fixed shaft 3 and the sleeve 5. When the bolt 4 passes through, it can evenly distribute the preload of the bolt 4 to the circumferential surface of the fixed shaft 3, avoiding stress concentration near the bolt 4 hole. The two ends of the reinforcing pad are respectively embedded in the bolt 4 hole of the sleeve 5 and the receiving hole of the reinforcing plate 6, forming a rigid support column. When the bolt 4 is tightened, the reinforcing pad can prevent the hole wall from undergoing plastic deformation (such as ellipticization) due to pressure, ensuring that the bolt 4 hole maintains its circular accuracy over a long period of time. The reinforcing plate 6 and the reinforcing pad are usually made of high-strength metal, which can withstand higher contact pressure and friction cycles compared to the plastic fixed shaft 3 and sleeve 5.

[0035] In some embodiments, the inner wall of the sleeve 5 is provided with a limiting groove 7, and the circumferential end of the reinforcing piece 6 can be engaged in the limiting groove 7. The position and shape of the limiting groove 7 are unique, and the reinforcing piece 6 can only be engaged in a specific direction to avoid misalignment of the bolt holes 4 due to incorrect installation. After the reinforcing piece 6 is engaged in the limiting groove 7, its circumferential degree of freedom is locked, and it cannot rotate relative to the sleeve 5. When the aircraft is subjected to steering torque, the reinforcing piece 6 can evenly transmit the force to the inner wall of the sleeve 5, avoiding uneven wear of the bolt holes 4 due to the slippage of the reinforcing piece 6.

[0036] Example 2

[0037] This utility model also provides a tricycle, including a handlebar axle 2 and the airplane handlebar in Embodiment 1, which makes the airplane handlebar more versatile and easy to install and disassemble.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
