Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0027] In the prior art, the traditional outboard engine head cover usually adopts a fixed closed structure or a split bolt connection design, resulting in poor accessibility of the internal chamber. When replacing the battery or maintaining the electronic components, the operator needs to disassemble the entire head cover or loosen multiple fasteners with tools, which has operation risks in the ship swaying environment. Some improved schemes try to set small size hatches on the side, but due to space layout, battery taking and placing are difficult and sealing performance is difficult to guarantee. Electric outboard engines generally place the battery compartment inside the main shell, and the user needs to disassemble the head cover and then operate in the engine compartment, which has the risk of cable interference and connector damage.

[0028] To solve the above problems, the inventors found that the main contradiction of the traditional structure is that operation convenience and structural reliability are difficult to balance. By analyzing the battery replacement scene in the ship environment, it is realized that the opening design in the vertical direction can effectively utilize the space height, and the flip opening and closing structure can avoid tool dependence. Further research found that integrating the display function in the openable component can not only simplify the operation steps, but also realize real-time acquisition of state information. Based on this, the head cover is divided into a fixed cover shell and a movable flip cover, and a large size opening is realized by rotating connection. Embodiments

[0029] As Figures 1-4As shown, the application proposes a flip type front screen display outboard engine head cover, including cover shell 1 and flip cover 2; cover shell 1 is used for fixed connection on the upper end of outboard engine main shell, and the inner part forms cover shell chamber 11 which is communicated with the inner part of outboard engine main shell, and the upper end of cover shell chamber 11 is provided with chamber opening 111; flip cover 2 is rotationally connected to the side wall of chamber opening 111, and opens or closes chamber opening 111 through flip movement. Among them, cover shell 1 refers to the shell structure fixedly connected with the main shell of outboard engine, which can be manufactured by injection molding process, and the inner chamber is communicated with the inner part of the main shell to form a continuous space for accommodating battery 8 and electronic components. Flip cover 2 refers to the movable part covering chamber opening 111, which can be rotationally connected with cover shell 1 through hinge or shaft, and forms a vertical access channel in the open state. Chamber opening 111 refers to the through structure provided on the top of cover shell 1, which can be designed as rectangular or trapezoidal profile, and the opening area can cover the maximum cross-sectional dimension of battery 8, which is convenient for battery 8 to enter and exit without obstacles.

[0030] Specifically, cover shell 1 is fixed on the upper end of outboard engine main shell by bolt or clamping method, forming an expanded space communicated with the inner part of the main shell. The rear end of flip cover 2 is connected to the edge of chamber opening 111 through a shaft, and the front end is kept closed by a lock mechanism. When the battery 8 needs to be replaced, the flip cover 2 is flipped up after the front end lock is released, so that the chamber opening 111 is completely exposed. At this time, the battery 8 can be directly taken out along the vertical direction, avoiding the interference of horizontal movement in the traditional structure. When the flip cover 2 is closed, its edge forms a sealing contact surface with the chamber opening 111, which realizes leakage protection through waterproof rubber strip. Through the above technical scheme, the application realizes the tool-free quick opening of the battery compartment, and the operation steps are simplified from multiple disassembly actions of the traditional structure to a single flip action. The vertical opening design makes the battery 8 taking and placing process without inclination or rotation, reducing the operation risk in the ship sway environment. The rotation connection structure of flip cover 2 and cover shell 1 avoids the loss of separated parts, while maintaining the overall waterproof performance. The display screen 7 integrated on the surface of flip cover 2 can still display real-time data in the open state, which is convenient for users to monitor the equipment status when replacing the battery 8.

[0031] In specific embodiments, the rear end of the cover 2 is hingedly connected to the shell 1, and the front end of the cover 2 is detachably connected to the shell 1 by a buckle structure. The rear end hinge refers to a rotatable connection between the cover 2 and the shell 1 through a rotating shaft or hinge, which can be achieved by a pin shaft cooperating with a hinge seat, so that the cover 2 can rotate around the fixed axis to avoid positional deviation caused by overall displacement. The buckle structure refers to a component that achieves quick connection and separation through mechanical interlocking, which can be achieved by a combination of an elastic hook 3 and a card mouth 21, and the locking force is generated by elastic deformation to complete the closing and opening of the cover 2 without the aid of tools. Specifically, the rotating support point formed by the rear end hinge provides a stable motion trajectory for the cover 2, ensuring the alignment accuracy between the cover 2 and the shell 1 during opening and closing; the front end buckle structure keeps the hook 3 and the card mouth 21 in a locked state through the pre-tightening force of the elastic part 4, forming a rigid constraint during closing to prevent accidental disconnection in a vibrating environment. In the opening operation, only the external force is applied to the buckle to release the interlocking, and the cover 2 can be opened by rotating around the rear end hinge shaft. The entire process does not require disassembly of bolts or use of tools. The cooperation of the rear end hinge and the front end buckle forms a double fixation mechanism, which not only maintains the structural stability in the closed state, but also reduces the wear and tear of components caused by frequent operation.

[0032] As shown in Figure 2 and 3 , the hook 3 is movably arranged on the inner side of the front end of the shell 1, the hook 3 is connected to the elastic part 4 and the lever 5 extending to the outer side of the front end of the shell 1, and the card mouth 21 is arranged on the inner side of the front end of the cover 2. When the hook 3 is inserted into the card mouth 21, the cover 2 achieves the closure of the chamber opening 111. The hook 3 refers to a movable component with locking function, which can be realized by metal stamping or injection molding, and its horizontal movement trajectory is constrained by the guide groove inside the shell 1. The elastic part 4 refers to an element that provides a restoring force, which can be realized by a coil spring or a spring sheet, and is used to maintain the hook 3 in the locked position without external force. The lever 5 refers to an operating component linked with the hook 3, which can be realized in the form of a rod or a push button, and the exposed part is provided with anti-slip patterns to enhance the operation convenience. The card mouth 21 refers to a groove matched with the shape of the hook 3, which can be realized by milling or mold forming, and its depth size is greater than the height of the protruding part of the hook 3 to ensure the stability of the engagement.

[0033] Further, the upper end of the hook 3 is provided with a slope 31, which is pressed and guided by the cover 2 during the closing process of the cover 2, and is clamped into the card slot 21. The slope 31 refers to the inclined guide surface arranged on the top of the hook 3, which can be realized by a metal or plastic slope structure with an inclination angle of 15-45 degrees. The slope 31 is in contact with the closing track of the cover 2, and is used to convert the vertical downward pressure into horizontal displacement driving force. The horizontal movement refers to the displacement of the hook 3 in the direction parallel to the front end surface of the housing 1, which can be realized by the cooperation of the slide rail arranged on the bottom of the hook 3 and the slide groove on the inner side of the housing 1.

[0034] Specifically, when the cover 2 is closed downward, the front end edge of the cover 2 first contacts the slope 31 of the hook 3. As the cover 2 continues to press downward, the slope 31 and the cover 2 generate interaction force on the contact surface, forcing the hook 3 to move horizontally along the slide groove away from the cover 2. At this time, the elastic component 4 connected to the hook 3 is compressed to store energy, and when the cover 2 is completely closed, the card slot 21 moves to the position aligned with the hook 3. The elastic component 4 releases the stored energy to push the hook 3 to move reversely horizontally, so that the end of the hook 3 is accurately embedded into the card slot 21 to form a lock. During this process, the slope 31 structure automatically corrects the positional deviation between the cover 2 and the hook 3, and the self-alignment locking can be completed without manual intervention. At this time, the vertical displacement of the cover 2 is blocked by the hook 3, and the horizontal displacement is limited by the friction between the hook 3 and the side wall of the card slot 21, so as to resist accidental opening caused by ship vibration. When it is needed to open, the hook 3 is driven to disengage from the card slot 21 by pulling the lever 5 outward, and the cover 2 can be opened after the lock is released. Through the above technical solution, the problem of accidental opening of the cover 2 in the ship vibration environment is effectively solved, and the quick opening and closing of single-handed operation is realized. The cooperation of the hook 3 and the elastic component 4 does not need to be maintained by continuous external force in the locked state, avoiding the problem of power dependence of the traditional electromagnetic lock. The external design of the lever 5 makes the unlocking operation without the intervention of tools, which significantly improves the replacement and maintenance efficiency of the battery 8.

[0035] Through the above technical solution, the self-alignment function of the locking mechanism during the closing process of the cover 2 is realized, and the misalignment problem of the hook 3 and the card slot 21 caused by assembly error or environmental vibration is effectively solved. Only single pressing of the cover 2 is needed during operation to complete the locking, avoiding the operation steps of repeatedly adjusting the position of the hook 3, and reducing the friction loss between the locking components through the mechanical self-locking mechanism, which significantly improves the closing efficiency and long-term use reliability of the outboard motor battery compartment cover.

[0036] As Figure 3 and 4As shown, the rear end of the flip cover 2 is connected with the shell 1 through the turnover frame 6, and the turnover frame 6 comprises an L-shaped hinged arm 61, the lower end of the L-shaped hinged arm 61 is rotatably connected with the inner side of the rear end of the shell 1, and the upper end is fixedly connected with the rear end of the flip cover 2. Wherein, the turnover frame 6 refers to a mechanical linkage assembly connecting the flip cover 2 and the shell 1, which can be realized by metal stamping parts or injection molded parts, and its function is to convert the turnover action of the flip cover 2 into the rotary motion of the hinged arm, avoiding the linear friction of the traditional straight arm hinge. Wherein, the L-shaped hinged arm 61 refers to a rigid connecting piece with a spatial bending shape, which can be realized by a steel plate bent at 90 degrees, and its function is to disperse the stress at the hinged part by lengthening the rotation path, and to provide multiple rotation fulcrums for the opening of the flip cover 2. Wherein, the rotary connection refers to an assembly method that allows the part to rotate around the axis, which can be realized by a pin shaft and a shaft sleeve cooperation structure, and its function is to provide a stable rotation axis for the L-shaped hinged arm 61, so that the flip cover 2 moves along the predetermined track. Specifically, the lower end of the L-shaped hinged arm 61 forms a rotary pair with the inner side of the rear end of the shell 1 through a pin shaft, and the upper end is rigidly connected with the rear end of the flip cover 2 through bolts or welding. When the flip cover 2 is opened, the L-shaped hinged arm 61 rotates around the lower end pin shaft, and the bending part forms a lever effect, so that the flip cover 2 generates an increasing resistance during the opening process, avoiding sudden falling due to gravity. The L-shaped structure of the hinged arm forms a spatial limit when the flip cover 2 is fully opened, and maintains the open state through geometric self-locking.

[0037] Further, an arc-shaped positioning groove 611 is arranged at the lower end of the L-shaped hinged arm 61, and a positioning column 12 is arranged inside the shell 1; when the flip cover 2 is fully opened, the arc-shaped positioning groove 611 is clamped with the positioning column 12 to maintain the open state. Wherein, the L-shaped hinged arm 61 refers to a connecting part with a vertical turning structure, which can be realized by metal stamping parts or injection molded parts, and the lower end is connected with the shell 1 through a rotating shaft, and the upper end is fixed with the flip cover 2, forming the fulcrum of the turnover motion. Wherein, the arc-shaped positioning groove 611 refers to a curved groove opened at the lower end of the hinged arm, which can be realized by milling or mold forming, and its arc is matched with the opening track of the flip cover 2, used for clamping with the positioning column 12 at a certain angle. Wherein, the positioning column 12 refers to a protruding structure fixed inside the shell 1, which can be realized by bolts or welding parts, and its position corresponds to the terminal point of the track of the arc-shaped positioning groove 611, used for limiting the rotation range of the hinged arm. Specifically, when the flip cover 2 is lifted to the fully open position, the L-shaped hinged arm 61 rotates with the flip cover 2 to drive the arc-shaped positioning groove 611 to move along the predetermined path. When the arc-shaped positioning groove 611 moves to the position aligned with the positioning column 12, the positioning column 12 is embedded in the groove, preventing the hinged arm from continuing to rotate through mechanical interference. At this time, the opening angle of the flip cover 2 is locked and cannot be closed automatically under the action of gravity or external vibration. The curved shape of the arc-shaped positioning groove 611 allows the hinged arm to smoothly transition during rotation, and only forms a rigid clamping with the positioning column 12 when fully opened, avoiding accidental jamming during the movement process.

[0038] As Figure 1 shown, the display screen 7 is embedded in the front end face of the cover 1, and the display screen 7 is used to display at least one of the battery 8 state, the outboard motor operating parameter, the power, the gear and the speed. Among them, the front end face of the cover 1 embedded display screen 7 refers to the display module is directly integrated in the front area of the head cover, which can be achieved by using embedded installation structure, for example, when the cover 1 is injection molded, the installation groove is reserved, and the display screen 7 is fitted with the groove by the waterproof rubber ring. This layout makes the display screen 7 in the user's direct vision range, avoiding the obstruction of the view when the flip cover 2 is opened and closed. Among them, the display information contains at least one of the battery 8 state, the operating parameter, the power, the gear and the speed, which means that the display screen 7 supports multiple types of data integrated display, which can be achieved by using programmable control chip, for example, through CAN bus to receive the real-time data output by the outboard motor control unit, and after processing, the display screen 7 is driven to update the display content. This design replaces the single function display mode of traditional separate type indicator light. Specifically, the display screen 7 is fixedly installed on the non-moving area of the front end face of the cover 1, and the display interface thereof faces outward. When the flip cover 2 is in the closed state, the user can directly observe the battery 8 remaining power percentage, the current speed value and other parameters displayed by the display screen 7, without the need to open the flip cover 2 to obtain the key information. During the battery 8 replacement process when the flip cover 2 is opened, the display screen 7 continuously displays the outboard motor operating state, avoiding the parameter monitoring blind area caused by the interruption of operation. The embedded installation mode of the display screen 7 makes it flush with the surface of the cover 1, reducing the sensitivity of the external protruding structure to water flow impact. Embodiment

[0039] As Figure 5 shown, an outboard motor includes an outboard motor shell 9 and a battery 8, the outboard motor shell 9 includes an outboard motor main shell and a flip cover with front display, the outboard motor head cover adopts the scheme recorded in embodiment 1, the outboard motor main shell and the head cover inside jointly form a battery compartment, and the battery 8 is detachably accommodated in the battery compartment. When the flip cover 2 is opened, the battery 8 is taken out through the cavity opening 111. The flip cover with front display of the outboard motor head cover refers to the structure of the cover body integrating the display screen 7 and the flip cover, which can realize the rotary motion of the flip cover 2 by using hinge connection or shaft mechanism. The structure directly exposes the opening of the battery compartment through the opening operation of the flip cover 2. Among them, the battery compartment is jointly formed by the outboard motor main shell and the head cover inside, which means that the butt joint surface of the main shell and the head cover realizes continuous cavity structure through the sealing ring. Specifically, it can be achieved by using concave-convex embedded edge cooperation waterproof rubber strip. This design eliminates the assembly gap of the traditional split type structure, and ensures the airtightness of the battery compartment. Among them, the cavity opening 111 takes out the battery 8, which means that the battery 8 moves vertically along the direction of gravity, and the taking-out path can be achieved by the vertical channel formed after the flip cover 2 is opened. The size of the channel matches the shape of the battery 8, avoiding the cable bending caused by lateral movement.

[0040] Specifically, when the flip cover 2 is in the closed state, the continuous cavity formed by the head cover and the main shell completely wraps the battery 8, and the display screen 7 displays the state parameters of the battery 8 in real time. When operating, only the buckle restraint at the front end of the flip cover 2 is released and flipped upward, and the cavity opening 111 is completely exposed, at which time the battery 8 can be directly extracted or placed in the vertical direction. The flip cover 2 is arranged in parallel with the battery 8 extraction and placement path, so that the opening size is maximized and the battery 8 attitude does not need to be adjusted. The guide groove arranged on the inner wall of the battery compartment cooperates with the protruding structure on the side surface of the battery 8, further ensuring the accurate alignment of the battery 8 and the cable interface during extraction and placement. Compared with the prior art, the traditional outboard engine needs to disassemble the entire head cover or operate the independent hatch to extract and place the battery 8, and the structure of the present solution opens the battery compartment opening through the flip cover 2 linkage, which simplifies the operation steps to a single flip action. The lateral opening hatch in the prior art causes difficulty in extracting and placing the battery 8 due to space limitations, and the present solution uses a vertical opening to make the movement trajectory of the battery 8 consistent with the direction of gravity, which not only reduces the operation difficulty but also avoids stress on the cable. In addition, the assembly surface of the traditional split head cover and the main shell is prone to water seepage, and the present solution effectively improves the waterproof reliability through the integrated battery compartment structure and multiple seals when the flip cover 2 is closed.

[0041] Further, the upper end of the battery 8 is provided with a handle 81. The handle 81 refers to a gripping structure arranged on the top of the battery 8, which can be implemented in a ring shape, a U shape or a T shape, and the material can be hard plastic or metal, which is fixed on the battery 8 shell by embedding or bolt connection. The width and height of the handle 81 can be adjusted according to the size of the battery 8, and the surface can be provided with anti-slip lines or covered with soft material to enhance the friction. This structure forms a stable force point during the vertical extraction and placement of the battery 8, avoiding the battery 8 from slipping due to the rocking of the ship. When the flip cover 2 is opened, the operator directly grips the battery 8 through the handle 81 to move in the vertical direction. The installation position of the handle 81 is aligned with the center of gravity of the battery 8, ensuring that the battery 8 remains balanced during the lifting process. The distance between the top of the handle 81 and the inner wall of the flip cover 2 is designed to be greater than the thickness of the palm, so that the operator can complete the gripping action without having to put his hand into the cavity. When the ship is rocking, the anti-slip surface of the handle 81 increases the contact area with the fingers, disperses the impact load through multi-point force, and prevents the battery 8 from being separated from the grip due to inertia. The arc-shaped edge of the handle 81 can guide the palm to naturally fit, adapting to different gripping angles.
