The existence of the waterproof groove changes the flow path of the liquid on the surface of the first shell, and when the liquid flows through the side of the first shell away from the screen, the liquid is blocked and guided by the waterproof groove, so that the liquid is difficult to directly pass through the waterproof groove and enter the placement area, and the waterproof groove plays a role in buffering and blocking the external liquid to a certain extent.

Description

Technical Field

[0001] This application relates to the field of vehicle displays, and more particularly to a motorcycle display with a novel fixed structure. Background Technology

[0002] A motorcycle infotainment system is an intelligent electronic device integrated into a motorcycle. Its main function is to provide riders with comprehensive services such as navigation, entertainment, communication, vehicle status monitoring, and safety assistance. It interacts with users through a touchscreen, voice control, or physical buttons, and combines technologies such as GPS, Bluetooth, and 4G / 5G networks to enhance the convenience, safety, and entertainment of riding.

[0003] During motorcycle riding, the motorcycle infotainment system serves as a crucial information display component, providing riders with key data such as speed, RPM, and fuel level, greatly enhancing the convenience and safety of the ride. However, some motorcycle infotainment systems currently on the market have significant structural design flaws, particularly in their poor waterproofing performance.

[0004] Specifically, some motorcycle infotainment systems lack effective waterproofing. Their casing designs are often quite simple, and the connections between components lack necessary sealing measures. In real-world motorcycle use, riders face various complex weather conditions, such as heavy rain and snow, and may also encounter flooded roads. Under these circumstances, external liquids can easily enter the display through gaps in the casing and at joints.

[0005] Once external liquids enter the motorcycle's infotainment system, they can cause serious damage to its delicate internal components. The circuit boards, chips, and other components inside the display are extremely sensitive to moisture. Moisture can lead to short circuits, component corrosion, and other problems, affecting the normal operation of the display and potentially causing it to be completely destroyed, unable to provide the rider with critical information. This not only affects the convenience of riding but also poses a potential threat to riding safety.

[0006] Therefore, how to design a motorcycle infotainment system with a novel fixed structure and good waterproof performance to effectively prevent external liquids from entering the display and protect internal components from damage has become a pressing technical problem in the current motorcycle infotainment system field. Utility Model Content

[0007] In view of this, it is necessary to provide a motorcycle display with a new type of fixed structure to solve the problem that some motorcycle display systems do not have an effective waterproof structure, and external liquids can easily enter the display through gaps in the display casing, joints and other parts.

[0008] Embodiments of this application provide a motorcycle engine with a novel fixed structure, comprising: Screen; A first housing, the screen is disposed on the first housing, a first sealing ring is provided between the screen and the first housing, and a waterproof groove is provided on the side of the first housing away from the screen; The second housing is located on the side of the first housing away from the screen. A placement area is formed between the second housing and the first housing. The second housing is provided with a waterproof structure corresponding to the waterproof groove. The waterproof structure is located inside the waterproof groove and prevents external water from entering the placement area.

[0009] In at least one embodiment of this application, the first housing is provided with a memory card slot and a cover plate covering the memory card slot, and a second sealing ring is provided between the cover plate and the memory card slot.

[0010] In at least one embodiment of this application, the cover plate is bolted to the first housing.

[0011] In at least one embodiment of this application, the motorcycle engine with the novel fixed structure further includes a power socket disposed on the second housing and a power plug electrically connected to the power socket, the power plug covering the power socket, and a third sealing ring being provided between the power plug and the power socket.

[0012] In at least one embodiment of this application, the power plug includes a positioning part and a contact part, the positioning part is disposed on the power socket, the third sealing ring is disposed between the power socket and the positioning part, the power socket is electrically connected to the power socket, and the power socket is provided with a fourth sealing ring, the fourth sealing ring preventing external water from entering the placement area.

[0013] In at least one embodiment of this application, the power socket and the power plug are electrically connected via a Type-C interface.

[0014] In at least one embodiment of this application, the first housing and the second housing are bolted together.

[0015] In at least one embodiment of this application, the motorcycle engine with the novel fixed structure further includes a circuit board electrically connected to the screen, the circuit board being located within the placement area.

[0016] In at least one embodiment of this application, the power plug is bolted to the second housing.

[0017] The motorcycle head unit with the novel fixed structure described above forms a reliable sealing barrier at the connection interface between the screen and the first housing by setting a first sealing ring between them. When external liquid comes into contact with the motorcycle head unit, the first sealing ring effectively prevents the liquid from seeping into the display from the gap between the screen and the first housing. Simultaneously, a waterproof groove is formed on the side of the first housing away from the screen, providing dedicated space for the subsequent waterproof structure. The presence of the waterproof groove alters the flow path of the liquid on the surface of the first housing. When the liquid flows across the side of the first housing away from the screen, it is blocked and guided by the waterproof groove, making it difficult for the liquid to directly cross the groove and enter the placement area, thus buffering and blocking external liquids to a certain extent.

Detailed Implementation

[0020] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0021] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0022] Embodiments of this application provide a motorcycle engine with a novel fixed structure, comprising: Screen; A first housing, the screen is disposed on the first housing, a first sealing ring is provided between the screen and the first housing, and a waterproof groove is provided on the side of the first housing away from the screen; The second housing is located on the side of the first housing opposite to the screen, forming a placement area between the second housing and the first housing. The second housing has a waterproof structure corresponding to the waterproof groove, located within the waterproof groove. This waterproof structure prevents external water from entering the placement area. The motorcycle engine with the novel fixing structure described above, by setting a first sealing ring between the screen and the first housing, forms a reliable sealing barrier at the connection interface between the screen and the first housing. When external liquid comes into contact with the motorcycle engine with the novel fixing structure, the first sealing ring effectively prevents the liquid from seeping into the display from the connection gap between the screen and the first housing. Simultaneously, the waterproof groove on the side of the first housing opposite to the screen provides dedicated space for the subsequent waterproof structure. The presence of the waterproof groove alters the flow path of the liquid on the surface of the first housing. When the liquid flows through the side of the first housing opposite to the screen, it is blocked and guided by the waterproof groove, making it difficult for the liquid to directly cross the waterproof groove and enter the placement area, thus buffering and blocking external liquids to a certain extent.

[0023] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please see Figures 1-7 Embodiments of this application provide a motorcycle engine 100 with a novel fixed structure, comprising: Screen 1; A first housing 2, a screen 1 is disposed on the first housing 2, a first sealing ring 4 is provided between the screen 1 and the first housing 2, and a waterproof groove 21 is provided on the side of the first housing 2 away from the screen 1. The second housing 3 is located on the side of the first housing 2 away from the screen 1. A placement area A is formed between the second housing 3 and the first housing 2. The second housing 3 is provided with a waterproof structure 31 corresponding to the waterproof groove 21. The waterproof structure 31 is located inside the waterproof groove 21 and prevents external water from entering the placement area A.

[0025] Specifically, screen 1, as an information display component of the motorcycle's infotainment system 100 with a novel fixed structure, is used to present key riding information such as speed, RPM, fuel level, and mileage to the rider, helping them understand the motorcycle's operating status in a timely manner. It provides intuitive and clear visual information, improving riding safety and convenience. The method of displaying this riding information through screen 1 is an existing method in the industry. The first housing 2 serves as the mounting carrier for screen 1, providing physical support and protection. Simultaneously, the waterproof groove 21 and the first sealing ring 4 on it together constitute an important part of the waterproof system, firmly fixing screen 1 and preventing damage due to vibration during motorcycle operation. Through cooperation with other waterproof structures 31, it effectively prevents external water from entering the display, protecting internal components. The first sealing ring 4 between the screen 1 and the first housing 2 forms a seal at the connection interface between the screen 1 and the first housing 2, filling the gap between them. When external liquids (such as rainwater, splashing water, etc.) come into contact with the motorcycle engine 100 with the novel fixed structure, the first sealing ring 4 can effectively prevent liquids from seeping into the display from the connection gap between the screen 1 and the first housing 2, avoiding problems such as internal circuit short circuits or component corrosion caused by liquid intrusion, thus improving the waterproof performance of the display. The waterproof groove 21 on the side of the first housing 2 away from the screen 1 changes the flow path of liquids on the surface of the first housing 2, providing space for the subsequent waterproof structure 31 to accommodate and function. When liquids flow through the side of the first housing 2 away from the screen 1, the waterproof groove 21 blocks and guides the liquids, making it difficult for the liquids to directly cross the waterproof groove 21 and enter the placement area A, thus buffering and blocking external liquids to a certain extent, further enhancing the waterproof effect. The second housing 3 cooperates with the first housing 2 to form the placement area A, which is used to accommodate various internal components of the motorcycle engine 100 with the novel fixed structure, such as circuit boards 9, chips, sensors, etc. Meanwhile, the waterproof structure 31 on it corresponds to the waterproof groove 21 of the first housing 2, together forming a waterproof barrier, concentrating the internal components in the placement area A for easy management and maintenance. In conjunction with the waterproof structure 31 of the first housing 2, it effectively prevents external water from entering the placement area A, protecting the internal components from liquid damage. The placement area A formed between the second housing 3 and the first housing 2 provides a relatively independent and enclosed space for the internal components of the motorcycle engine 100 with its novel fixing structure, protecting these components from external environmental interference and damage, and concentrating the internal components for overall protection and management. Furthermore, in conjunction with other waterproof structures 31, it ensures that the components in the placement area A can function normally even in harsh environments.The waterproof structure 31 on the second housing 3, corresponding to the waterproof groove 21, fits tightly with the waterproof groove 21 on the first housing 2 to form a complete waterproof system, blocking external water from entering the placement area A. The waterproof structure 31 can take various forms, such as rubber sealing strips, raised ribs, etc., which can fit tightly against the inner wall of the waterproof groove 21 and effectively fill any gaps that may exist, thereby ensuring that external water cannot enter the placement area A and protecting the internal components from liquid damage.

[0026] In one specific example, the first housing 2 is provided with a memory card slot 22 and a cover plate 23 covering the memory card slot 22, and a second sealing ring 5 is provided between the cover plate 23 and the memory card slot 22.

[0027] Specifically, the first housing 2 is an important component of the motorcycle infotainment system 100 with a novel fixed structure. It provides structural support and protection for the entire display and serves as the basic platform for installing the memory card slot 22, cover plate 23, and other related components. The memory card slot 22, located on the first housing 2, is an opening structure for inserting a memory card. The memory card slot 22 typically has a specific shape and size to accommodate memory cards of corresponding specifications, such as common SD cards and TF cards. It contains metal contacts for contacting the metal contacts of the memory card to achieve data read and write transmission. The cover plate 23 covers the memory card slot 22, and its shape matches the memory card slot 22. It is generally installed on the first housing 2 by bolts or other fixing methods. The function of the cover plate 23 is to seal the memory card slot 22, preventing dust, moisture, and other external substances from entering the slot. The second sealing ring 5 is located between the cover plate 23 and the memory card slot 22, and is usually made of elastic and sealing materials such as rubber. Its shape conforms to the contact surfaces of the cover plate 23 and the memory card slot 22, allowing them to fit tightly together and provide a seal. Besides serving as the mounting base, the first housing 2 also protects components such as the memory card slot 22 and the cover plate 23 from damage caused by collisions, vibrations, or other external forces during motorcycle operation. The memory card slot 22 provides data storage and transmission functions. By inserting a memory card, the motorcycle's infotainment system 100 with its novel fixed structure can record various data during riding, such as mileage, speed, and time, facilitating subsequent viewing and analysis by the user. Simultaneously, data from the display can be exported to other devices for further processing. The cover plate 23 primarily functions to seal and protect the memory card slot 22. When the memory card is not inserted or removed, the cover plate 23 prevents dust, moisture, small insects, etc., from entering the slot, avoiding damage to the memory card and the slot, and ensuring the stability and reliability of data transmission. The second sealing ring 5 further enhances the sealing effect of the cover plate 23 on the memory card slot 22. It can fill the tiny gap between the cover plate 23 and the memory card slot 22, preventing liquid substances such as water and moisture from seeping into the slot, preventing the memory card and slot from short circuits and corrosion due to moisture, and improving the waterproof performance of the entire structure.

[0028] In one specific example, the cover plate 23 is bolted to the first housing 2.

[0029] Specifically, bolted connections are a common type of detachable connection that uses standard components such as bolts, nuts, and washers to tightly fasten two or more connected parts together. They are widely used in mechanical structures and equipment assembly, offering advantages such as reliable connection and convenient assembly and disassembly. In the scenario where the cover plate 23 is bolted to the first housing 2, the connected parts include the cover plate 23 and the first housing 2. The cover plate 23 is used to enclose structures such as the memory card slot 22, protecting internal components and providing dust and water resistance; the first housing 2 is the main support structure of the motorcycle engine 100 with its novel fixing structure, providing a mounting base for other components. A connecting bolt generally consists of two parts: a head and a shank. The head comes in different shapes, such as hexagonal or round, and is used for tightening with tools. The shank has external threads for mating with a nut to achieve the connection. The nut matches the bolt's shank and has internal threads. By screwing it onto the bolt, it clamps the cover plate 23 and the first housing 2. Washers are usually placed between the bolt head or the nut and the connected parts to increase the contact area, distribute pressure, prevent loosening, and protect the surface of the connected parts. The connection process of the cover plate 23 to the first housing 2 involves determining a suitable connection position on the cover plate 23 and the first housing 2, and then using a drilling tool (such as a drill press) to drill a through hole at the corresponding position that matches the bolt diameter. The size and position of the hole need to be precisely controlled to ensure the accuracy and reliability of the connection. The washer is placed on the bolt's shank, and then the bolt is passed through the through hole on the cover plate 23 and the first housing 2. A nut is installed on the other end of the bolt, and a suitable tool (such as a wrench) is used to gradually tighten the nut. During tightening, it is important to apply force evenly to avoid uneven stress on the bolts. Simultaneously, ensure that the tightening torque meets design requirements to guarantee the strength of the connection. Bolted connections can withstand significant tensile and shear forces. Through proper bolt layout and torque control, a tight connection between the cover plate 23 and the first housing 2 can be ensured, preventing loosening and maintaining a stable connection even under vibrations and impacts generated during motorcycle operation.

[0030] In one specific example, the motorcycle engine 100 with the novel fixed structure also includes a power socket 32 ​​disposed on the second housing 3 and a power plug 8 electrically connected to the power socket 32. The power plug 8 covers the power socket 32, and a third sealing ring 6 is provided between the power plug 8 and the power socket 32.

[0031] Specifically, the second housing 3 is an important component of the motorcycle engine 100 with a novel fixed structure. It is installed at a specific location within the motorcycle engine 100, providing a fixed mounting location for the power socket 32. In the motorcycle engine 100 with the novel fixed structure, the second housing 3 not only supports the power socket 32 ​​but also protects the internal circuitry and components to a certain extent, preventing them from being subjected to external physical impacts and damage. For example, during motorcycle operation, the second housing 3 must withstand vibrations and impacts, providing a stable operating environment for the internal components. The second housing 3 is typically made of high-strength, wear-resistant plastic or metal materials. Plastic materials have advantages such as light weight, low cost, and good insulation, meeting general protection requirements; metal materials have higher strength and can better resist external impacts, making them suitable for scenarios with higher protection requirements. Regardless of the material, the second housing 3 must possess a certain degree of rigidity and toughness to adapt to the complex operating environment of the motorcycle. The power socket 32 ​​is located on the second housing 3, serving as the interface for connecting the motorcycle engine 100 with the novel fixed structure to an external power source, used to receive electrical energy from the motorcycle battery or other power supply devices. It specifies the specifications and standards for power connections, ensuring that only compliant power plugs 8 can be inserted, thus guaranteeing the safe transmission of electrical energy. For example, the size of the socket, the number of pins, and their spacing are strictly regulated to prevent misinsertion and short circuits. The power socket 32 ​​generally has a specific geometric shape, such as rectangular or circular. It contains multiple metal conductive plates or contacts, the arrangement and specifications of which are determined by the design of the power plug 8. The conductive plates are typically made of highly conductive metals, such as copper, and their surfaces are treated to improve corrosion resistance and conductivity. For example, the surface of the copper conductive plate may be plated with nickel or other metals to enhance its oxidation resistance. The power plug 8 matches the power socket 32 ​​and is responsible for introducing electrical energy from an external power source into the motorcycle engine 100, which has a novel fixed structure. When power is needed, the power plug 8 is accurately inserted into the power socket 32 ​​to allow electrical energy transmission. It needs to have good conductivity and stable connection performance to ensure that there is no loosening or poor contact during motorcycle operation. For example, when the motorcycle is moving bumpily, the power plug 8 must maintain a reliable connection with the power socket 32 ​​to ensure the monitor can operate continuously and stably. One end of the power plug 8 has pins that correspond to the conductive plates or contacts inside the power socket 32. The shape and size of the pins need to be precisely designed to ensure a tight contact when inserted into the power socket 32, reducing contact resistance. The other end connects to the power cord. The material and specifications of the power cord are determined according to the transmitted current and voltage, and it is usually made of multi-strand copper core wire with an outer insulating material. For example, the insulation layer of the power cord may be made of polyvinyl chloride (PVC), which has good insulation properties and aging resistance.The third sealing ring 6 is located between the power plug 8 and the power socket 32. Its main function is to seal, filling the tiny gaps between them and preventing the infiltration of liquids such as moisture and humidity. This prevents short circuits and corrosion caused by dampness, thus improving the waterproof performance of the power connection. It also helps prevent dust and other solid particles from entering, protecting the internal structure of the power socket 32 ​​and the plug. The third sealing ring 6 is typically made of elastic and sealing materials such as rubber or silicone. Its shape matches the contact surfaces of the plug and socket, allowing for a tight fit and forming a sealed barrier. The surface of the sealing ring is usually specially treated to improve its wear resistance and sealing performance. For example, silicone sealing rings may have a matte finish to reduce the coefficient of friction and enhance the sealing effect.

[0032] In a specific example, the power plug 8 includes a positioning part 81 and a contact part 82. The positioning part 81 covers the power socket 32. A third sealing ring 6 is disposed between the power socket 32 ​​and the positioning part 81. The power socket 32 ​​is electrically connected to the power socket 32. A fourth sealing ring 7 is provided on the power socket 32. The fourth sealing ring 7 prevents external water from entering the placement area A.

[0033] Specifically, the positioning part 81 plays a crucial role in the process of inserting the power plug 8 into the power socket 32. It acts like a precise navigation system, ensuring the plug is inserted accurately. When the power plug 8 is brought close to the power socket 32 ​​for insertion, the positioning part 81, with its specific shape and structure, guides the plug into the correct direction and position. Some positioning parts 81 may be designed with protrusions or grooves that match the corresponding structures on the power socket 32, thus preventing the plug from being inserted crookedly or at an angle. If the plug is inserted crookedly, it may lead to poor contact, affecting the normal transmission of power, and may even damage the plug or socket. After the plug is successfully inserted into the power socket 32, the positioning part 81 also plays a role in stabilizing the connection. In daily life, electrical appliances may be affected by various external forces, such as slight shaking or pulling. The positioning part 81 can prevent the plug from loosening or falling off due to these external forces, ensuring a tight connection between the plug and the socket, thereby ensuring the stability of power transmission. For example, when moving some electrical appliances, the positioning part 81 can prevent the plug from disconnecting due to shaking, avoiding sudden power outages. The positioning part 81 acts like a lid, completely or partially covering the outside of the power socket 32. This assembly method not only enhances the stability of the connection between the plug and the socket but also protects the contact parts 82 inside the power socket 32 ​​to a certain extent. When the positioning part 81 is placed on the power socket 32, the third sealing ring 6 is compressed by both, causing it to deform and tightly fill the gap, forming an effective sealing barrier. This barrier prevents external liquids such as water and moisture from entering the device through the gap between the power socket 32 ​​and the positioning part 81. When the power plug 8 is inserted into the power socket 32, the contact parts 82 on the plug come into contact with the conductive components inside the socket, forming a complete electrical path. During this process, factors such as the contact pressure and contact area between the contact parts 82 and the conductive components affect the quality of the electrical connection. The fourth sealing ring 7 is usually installed at the part where the power socket 32 ​​connects to the device housing or on the outer periphery of the socket. Sealing at this location is crucial for preventing external water, dust, etc., from entering the device. Unlike the third sealing ring 6, which primarily seals the connection between the positioning part 81 and the power socket 32, the fourth sealing ring 7 primarily seals the connection between the power socket 32 ​​and the device casing. It prevents external water from entering the device along the outer surface of the power socket 32, further enhancing the device's waterproof performance. The placement area A can be understood as the area inside the electrical equipment used to house important electronic components such as the power plug 8 and circuit board 9. These electronic components have high environmental requirements and need to be kept dry and clean to ensure their proper functioning. If external water enters placement area A, it may cause short circuits or damage to the electronic components, thus affecting the performance of the entire electrical device. For example, water entering the electronic components on circuit board 9 may cause electrical faults, leading to the device failing to start or malfunctioning.The third sealing ring 6 and the fourth sealing ring 7 can be made of rubber.

[0034] In one specific example, the power socket 32 ​​and the power plug 8 are electrically connected via a Type-C interface.

[0035] Specifically, the Type-C interface is a new type of Universal Serial Bus (USB) interface with a unique appearance and electrical characteristics. Its interface shape is a symmetrical oval, allowing insertion from either side. This design solves the problem of needing to distinguish between the front and back of the traditional USB interface, making it more convenient to use. In the power connection scenario of the motorcycle infotainment system 100 with its new fixed structure, the power socket 32 ​​and the power plug 8 are electrically connected using the Type-C interface. This means that both have physical structures and electrical parameters that match the Type-C interface, enabling stable and efficient power transmission. When the power plug 8 is inserted into the power socket 32, the metal contacts of the Type-C interface will make contact with each other. The Type-C interface has multiple pins, including power pins (such as the VBUS pin for power transmission), ground pins (GND), and data transmission pins. In the power connection, the power pins and ground pins are mainly used to establish the power transmission path. From an electrical perspective, the circuitry on the power socket 32 ​​side adjusts the electrical energy from the external power source (such as a motorcycle battery) to a voltage and current level suitable for the operation of the motorcycle infotainment system 100 with its novel fixed structure, and then transmits it to the power plug 8 via the power pins of the Type-C interface. Upon receiving the electrical energy, the power plug 8 then transmits it to the internal circuitry of the motorcycle infotainment system 100 with its novel fixed structure, powering various functional modules of the display (such as the display screen, processor, and sensors). For users and maintenance personnel of the motorcycle infotainment system 100 with its novel fixed structure, the reversible nature of the Type-C interface greatly improves operational convenience. Regardless of the environment in which power is connected, there is no need to spend time identifying the correct orientation of the interface; the power plug 8 can be quickly and accurately inserted into the power socket 32, reducing the risk of connection failure or interface damage due to incorrect insertion.

[0036] In one specific example, the first housing 2 and the second housing 3 are bolted together.

[0037] Specifically, bolted connections rely primarily on the mechanical engagement of bolts and nuts. A bolt typically consists of a head and a shank, with external threads on the shank; the nut has internal threads. After the bolt is passed through pre-drilled connection holes in the first housing 2 and the second housing 3, the nut is screwed on and tightened. The internal threads of the nut mesh with the external threads of the bolt. During tightening, the nut exerts an axial tensile force on the bolt, while the bolt also applies pressure to the first housing 2 and the second housing 3, ensuring a tight fit between the two housings. After the bolt is tightened, friction is generated between the threads of the bolt and nut, and between the bolt head or the nut and the housing surface. This friction prevents relative rotation between the bolt and nut, thus ensuring the stability of the connection. As long as the friction is sufficiently large, the bolted connection will not loosen under normal operating loads, reliably transmitting force and maintaining the relative position of the two housings.

[0038] In one specific example, the motorcycle vehicle unit 100 with the novel fixed structure also includes a circuit board 9, which is electrically connected to the screen 1 and is located in the placement area A.

[0039] Specifically, the circuit board 9 of the motorcycle infotainment system 100 with its novel fixed structure is the core control component of the entire display system, integrating various key electronic components. For example, the microprocessor (MCU) acts as the "brain" of the circuit board 9, processing data from various motorcycle sensors, such as speed sensors, RPM sensors, and fuel level sensors, and performing calculations and analyses on this data according to preset programs. In addition to the microprocessor, the circuit board 9 also contains a graphics processing unit (GPU), which converts the data processed by the microprocessor into image signals suitable for display on the screen 1. Furthermore, the circuit board 9 includes a power management module for regulating and filtering the input power, providing stable and appropriate voltage and current to the various components on the circuit board 9 and the screen 1, ensuring the normal operation of the entire display system. The electrical connection between the circuit board 9 and the screen 1 enables data transmission and power supply. The circuit board 9 transmits processed image signals and control signals to the screen 1 through specific lines, while simultaneously providing the screen 1 with the necessary power. Only after receiving these signals and power can the screen 1 display the corresponding images and information.

[0040] Common connection methods include the following: A ribbon cable can be used to connect the circuit board 9 to the screen 1, which is a relatively common connection method. A ribbon cable is a flat cable with multiple wires; one end connects to the ribbon cable interface on the circuit board 9, and the other end connects to the corresponding interface on the screen 1. Ribbon cables have the advantages of good flexibility and small footprint, allowing for convenient wiring inside the motorcycle's main unit 100 with its novel fixed structure. They can also withstand a certain degree of bending and vibration, making them suitable for the complex environment during motorcycle operation. The flexible circuit board 9 is a circuit board 9 made of a flexible substrate, featuring bendability and foldability. Similar to the ribbon cable, the flexible circuit board 9 can also connect the circuit board 9 and the screen 1 to achieve signal and power transmission. The connection of the flexible circuit board 9 is more reliable, reducing the problem of loosening due to vibration, and it can better adapt to the compact space layout inside the motorcycle's main unit 100 with its novel fixed structure. Given the limited internal space of the motorcycle's main unit 100 with its novel fixed structure, placing the circuit board 9 in a specific placement area A can make reasonable use of space and avoid interference between the circuit board 9 and other components. Placement area A is usually designed according to the size and shape of circuit board 9, which can ensure that circuit board 9 is installed firmly, while leaving enough space for other components (such as heat dissipation devices, connecting cables, etc.), making the internal layout of the entire display more compact and reasonable.

[0041] In one specific example, the power plug 8 is bolted to the second housing 3.

[0042] Specifically, the power plug 8 is the component used to connect the electric motorcycle to an external power source. It typically has two or three prongs, each corresponding to different voltage and current transmission functions. The plug's outer shell is generally made of insulating material, such as plastic, to prevent electric shock. Inside the plug, there is a metal conductive plate for contacting the conductive part of the external power socket to achieve power transmission. The second housing 3 is the external protective structure for the electric motorcycle's display or related electrical equipment. It not only protects the internal electronic components from external environmental influences (such as dust, moisture, and impacts) but also provides a mounting location for components such as the power plug 8. The second housing 3 is usually made of metal or high-strength plastic, possessing a certain degree of mechanical strength and durability. The bolts used to connect the power plug 8 and the second housing 3 need to be selected based on factors such as the stress on the connection point, space size, and ease of installation and disassembly. Common bolt types include hexagonal head bolts and countersunk head bolts. The diameter and length of the bolts must be determined according to the dimensions of the connecting holes on the power plug 8 and the second housing 3 to ensure that the bolts can securely pass through the connecting holes and be tightened. Connecting holes matching the bolts need to be machined on the power plug 8 and the second housing 3. The diameter of the connecting hole should be slightly larger than the nominal diameter of the bolt to ensure that the bolt can pass through smoothly, but not too large, so as not to affect the firmness of the connection. The position of the connecting hole must be precise to ensure that the power plug 8 and the second housing 3 can be correctly aligned after connection and meet the requirements of electrical connection and mechanical fixation. Pass the bolt through the connecting hole on the power plug 8 and the second housing 3, and then install a nut on the other end of the bolt. Use a suitable tool (such as a wrench) to tighten the nut to generate sufficient preload to tightly connect the power plug 8 and the second housing 3 together. When tightening the nut, pay attention to the tightening force to avoid overtightening, which may damage the bolt or housing, and undertightening, which may cause the connection to loosen. The bolted connection can provide a large connection force and can withstand various forces and vibrations that the power plug 8 is subjected to during operation. Electric motorcycles will generate bumps and vibrations during operation. The bolted connection can ensure that the power plug 8 is always firmly fixed to the second housing 3 and will not loosen or fall off due to vibration, thereby ensuring stable power transmission.
