Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a front hood lock mounting structure, a front hood system, and a vehicle. Background Technology

[0002] The vehicle front hood system includes the hood and the hood lock. The hood lock locks the front end of the hood to the front of the vehicle body. The height difference between the front end of the hood and the front of the vehicle body needs to meet aesthetic requirements, which is currently usually achieved by adjusting the hood lock's latch height, buffer pad height, or the hood lock's mounting dimensions.

[0003] Due to limitations imposed by the installation environment of the front hood lock, such as the diameter of the front hood lock hole, the specifications of the connectors, the fixing structure of the front hood lock buckle, and the closing force of the door, the existing technology cannot provide a larger adjustment range for the installation size of the front hood lock. This affects the further adjustment of the height difference between the front of the front hood and the front of the vehicle body, and consequently affects the aesthetic matching between the front of the front hood and the front of the vehicle body. Utility Model Content

[0004] In view of this, the embodiments of this application provide a front cover lock mounting structure, a front cover system and a vehicle, which solves the problem of small adjustment range of the existing front cover lock mounting dimensions and improves the aesthetics of the vehicle.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] In one aspect, embodiments of this application provide a front cover lock mounting structure.

[0007] The front cover lock mounting structure provided in this application embodiment includes:

[0008] A fastener, the fastener being installed in the engine compartment of a vehicle;

[0009] Front cover lock, the front cover lock having a through hole;

[0010] A connector having an axially connected reduced-diameter section and a connecting section, at least a portion of the reduced-diameter section being disposed within the through hole, and a gap being present between the circumferential outer wall of the reduced-diameter section and the wall of the through hole; the diameter of the reduced-diameter section being smaller than the diameter of the connecting section; and the connecting section being connected to the fastener.

[0011] The front hood lock mounting structure of this embodiment uses a fixing member for installation within the vehicle's engine compartment, providing a support platform for the front hood lock. The front hood lock has a through hole through which a connector passes. The connector connects to the fixing member, mounting the front hood lock onto the fixing member, thus installing the front hood lock within the engine compartment. The connector has a reduced-diameter section and a connecting section. The reduced-diameter section is located within the through hole, and there is a gap between the circumferential outer wall of the reduced-diameter section and the wall of the through hole. The diameter of the reduced-diameter section is smaller than the diameter of the connecting section, reducing the diameter of the connecting part that mates with the through hole and increasing the gap between the circumferential outer wall of the reduced-diameter section and the wall of the through hole. This increases the range of adjustment of the front hood lock within the through hole along the vehicle's height direction. Thus, with a fixed diameter and other factors, the installation height of the front hood lock on the vehicle can be adjusted by moving the front hood lock within the through hole along the vehicle's height direction. The current hood lock installation structure is applied to vehicles. After the hood is installed on the engine compartment and locked with the hood lock, there is still a certain adjustment margin for the height difference between the front end of the hood and the front end of the vehicle body. This increases the adjustment range of the height difference between the front end of the hood and the front end of the vehicle body, so that the height difference between the front end of the hood and the front end of the vehicle body can meet the design requirements of different vehicles, and thus meet the aesthetic requirements of matching the front end of the hood with the front end of the vehicle body.

[0012] In one possible implementation of this application, the gap between the circumferential outer wall of the reduced diameter section and the wall of the through hole is equal along the circumferential direction of the connector.

[0013] In one possible implementation of this application, the diameter of the reduced-diameter section is equal at all locations along the axial direction of the connector.

[0014] In one possible implementation of this application, the reduced diameter section is coaxially arranged with the through hole.

[0015] In one possible implementation of this application, the ratio of the difference between the diameter of the connecting segment and the diameter of the reduced-diameter segment to the diameter of the connecting segment is the reduction amount of the reduced-diameter segment, and the reduction amount is greater than or equal to 20% and less than or equal to 25%.

[0016] In one possible implementation of this application, the connector further has a fixed end along the axial direction, the fixed end being located on the side of the reduced diameter section opposite to the connecting section;

[0017] The reduced diameter section, the fixed end, and the connecting section form an annular groove in the circumferential direction of the connector, and the circumferential outer wall of the reduced diameter section forms the bottom wall of the annular groove.

[0018] In one possible implementation of this application, the front cover lock contacts the fixed end on the side facing the reduced diameter section to limit the position of the connector relative to the front cover lock in the axial direction.

[0019] In one possible implementation of this application, the reduced diameter section is arc-shapedly connected to at least one of the connecting section and the fixed end.

[0020] Secondly, embodiments of this application provide a front cover system, including:

[0021] A front cover, which is used to cover the engine compartment of a vehicle, has a front end and a rear end in the length direction, and the rear end is used to be movably connected to the body of the vehicle to open or close the engine compartment when in motion.

[0022] The front cover lock mounting structure provided in any of the embodiments of the first aspect above is disposed in the cabin and is opposite to and connected to the front end.

[0023] The front hood system provided in this application, since including the front hood lock mounting structure provided in any embodiment of this application, has the same effect: when the front hood lock mounting structure is applied to a vehicle, and after the front hood is mounted on the engine compartment and locked with the front hood lock, there is still a certain adjustment margin for the height difference between the front end of the front hood and the front end of the vehicle body. This increases the adjustment range of the height difference between the front end of the front hood and the front end of the vehicle body, so that the height difference between the front end of the front hood and the front end of the vehicle body can meet the design requirements of different vehicles, thereby satisfying the aesthetic requirements of matching the front end of the front hood with the front end of the vehicle body.

[0024] Thirdly, embodiments of this application provide a vehicle, including:

[0025] The vehicle body includes an engine compartment;

[0026] The front cover system provided in the second aspect above, wherein the front cover lock mounting structure of the front cover system is located inside the engine compartment and connected to the vehicle body; the front cover of the front cover system is mounted on the engine compartment and is movably connected to the vehicle body.

[0027] This application provides a vehicle that includes the front hood system provided in the second aspect above. The front hood system includes the front hood lock mounting structure provided in any embodiment of this application. Therefore, it has the same effect: when the front hood lock mounting structure is applied to the vehicle and the front hood is mounted on the engine compartment and locked with the front hood lock, the height difference between the front end of the front hood and the front end of the vehicle body still has a certain adjustment margin, thereby increasing the height difference adjustment range between the front end of the front hood and the front end of the vehicle body. This allows the height difference between the front end of the front hood and the front end of the vehicle body to meet the design requirements of different vehicles, thereby satisfying the aesthetic requirements of matching the front end of the front hood with the front end of the vehicle body.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0042] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0043] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0044] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0045] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0046] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0047] This application provides a vehicle embodiment. It should be noted that this application embodiment does not limit the vehicle type. For example, the vehicle in this application embodiment can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles.

[0048] The vehicle provided in this application includes a body and a front hood system. The body has an engine compartment. The front hood system includes a front hood and a front hood locking mounting structure. The front hood is mounted on the engine compartment.

[0049] In the vehicle's longitudinal direction, the engine compartment is located at the front of the body and houses the vehicle's powertrain, such as the engine and transmission. The front hood is a sheet metal component that covers the engine compartment. The front hood has a front end and a rear end. The rear end connects to the vehicle body. Using the connection point between the rear end of the front hood and the vehicle body as a fulcrum, the front hood moves around this fulcrum to open or close the engine compartment.

[0050] The front hood lock mounting structure is located inside the engine compartment and connected to the vehicle body. The front hood lock mounting structure is positioned opposite and can connect to the front end of the front hood. When the front hood lock mounting structure locks the front end of the front hood to the vehicle body, a complete body system is formed.

[0051] For example, the front cover is mounted on the cabin, and the rear end of the front cover can be connected to the vehicle body via a hinge. The front cover can rotate about the hinge axis to control the opening and closing of the cabin through the movement of the front cover.

[0052] The front hood lock mounting structure is located inside the engine compartment. For example, it can be installed on the upper front bulkhead assembly, the front longitudinal beam extension plate, or other similar locations. The front hood lock 200b is opposite the front end of the front hood, which has a latch. When the front hood moves downwards, the latch also moves downwards until it contacts and locks with the front hood lock 200b. At this point, the front hood is locked by the front hood lock 200b.

[0053] In vehicle design, the front end of the hood needs to create a smooth transition with the front of the vehicle body, such as the upper edge of the front bumper or the upper edge of the headlights, to meet aesthetic requirements. In terms of vehicle height, if the hood is too high, a noticeable step is created between the hood and the upper edge of the front bumper or headlights, which does not meet aesthetic requirements. If the hood is too low, a recess is created between the hood and the upper edge of the front bumper or headlights, which also does not meet aesthetic requirements.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 A schematic diagram of the front cover lock mounting structure provided for related technologies. Figure 2 A cross-sectional view (AA) of the front cover lock mounting structure provided for related technologies. Figure 3 A structural schematic diagram of the connector provided for related technologies.

[0055] In related technologies, the height difference between the front end of the front hood and the front end of the vehicle body is usually adjusted by adjusting the installation height of the front hood latch, the height of the front hood buffer pad, and the installation adjustment amount of the front hood lock 200a.

[0056] Specifically, the hood latch is located inside the hood and connects to the hood lock. The mounting height of the hood latch determines the height of the hood when closed. Raising the latch position increases the hood's closed position, widening the gap between the front of the hood and the front of the vehicle, resulting in a greater height difference. Lowering the latch position lowers the hood's closed position, narrowing the gap between the front of the hood and the front of the vehicle, resulting in a smaller height difference. However, the structure and installation relationship between the latch and the hood are usually fixed and cannot be adjusted.

[0057] The front hood buffer pad is installed inside the front hood or on the upper panel of the front bulkhead to support the front end of the hood. Increasing the height of the buffer pad increases the gap between the front end of the hood and the front end of the vehicle, resulting in a greater height difference. Conversely, decreasing the height of the buffer pad decreases the gap between the front end of the hood and the front end of the vehicle, resulting in a smaller height difference. In vehicles, the height of the front hood buffer pad is usually fixed and cannot be adjusted.

[0058] The front hood lock 200a is mounted on the vehicle body. Specifically, the front hood lock 200a has a through hole 210a, through which a connector 300a passes and connects to the fixing member 100, thus mounting the front hood lock 200a on the vehicle body. Adjusting the installation adjustment range of the front hood lock 200a is key; when the front hood lock 200a moves upward, the connection point with the front hood latch moves upward, thereby raising the front end of the front hood and increasing the gap between the front end of the front hood and the front end of the vehicle body, resulting in a larger height difference. When the front hood lock 200a moves downward, the connection point with the front hood latch moves downward, thereby lowering the front end of the front hood and decreasing the gap between the front end of the front hood and the front end of the vehicle body, resulting in a smaller height difference. However, since the hole diameter of the front hood lock 200a cannot be adjusted, the installation adjustment range of the front hood lock 200a is limited by the specifications of the connector 300a, and cannot meet the needs for larger installation adjustment ranges.

[0059] Therefore, when the front cover latch and the front cover structure are fixed, the height difference between the front end of the front cover and the front end of the vehicle body cannot be adjusted. Due to the installation environment of the front cover lock 200a, such as the size of the hole of the front cover lock 200a, the specification requirements of the connector 300a, and the force required to open and close the front cover, the adjustment of the installation adjustment of the front cover lock 200a can only be adjusted within a small range, which cannot meet the needs of a larger range of adjustment and makes it difficult to meet the aesthetic requirements of matching the front end of the front cover with the front end of the vehicle body.

[0060] Given that the structure and installation environment of the front hood lock 200a cannot be adjusted, how to achieve a wider range of adjustment for the distance between the front end of the front hood and the front end of the vehicle body is a technical problem that urgently needs to be solved.

[0061] In view of this, the present application provides a front cover lock mounting structure, in which the connector 300b has a reduced diameter section 310 and a connecting section 320. The reduced diameter section 310 is disposed within the through hole 210b, and there is a gap between the circumferential outer wall of the reduced diameter section 310 and the hole wall of the through hole 210b. The diameter of the reduced diameter section 310 is smaller than the diameter of the connecting section 320. By reducing a portion of the diameter of the connector 300b that mates with the through hole 210b, the gap between the circumferential outer wall of the reduced diameter section 310 and the hole wall of the through hole 210b is significantly increased, thereby improving the installation adjustment range of the front cover lock 200b, and further increasing the adjustment range of the distance between the front end of the front cover and the front end of the vehicle body, thus meeting the aesthetic requirements for matching the front end of the front cover with the front end of the vehicle body.

[0062] The front cover lock mounting structure provided in this application will be further described below with reference to the accompanying drawings and embodiments.

[0063] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, Figure 4 This is an assembly diagram of the front cover lock mounting structure provided in an embodiment of this application. Figure 5 This is a schematic diagram of the front cover lock mounting structure provided in an embodiment of this application. Figure 6 This is a BB cross-sectional view of the front cover lock mounting structure provided in an embodiment of this application. Figure 7 This is a schematic diagram of the connector provided in an embodiment of this application.

[0064] This application provides a front hood lock mounting structure including a fixing member 100, a front hood lock 200b, and a connecting member 300b. The fixing member 100 is located inside the engine compartment of the vehicle. The front hood lock 200b has a through hole 210b. The connecting member 300b includes a connecting section 320 and a reduced diameter section 310. The connecting section 320 is connected to the fixing member 100, and the reduced diameter section 310 is engaged with the through hole 210b to fix the front hood lock 200b inside the engine compartment.

[0065] At least a portion of the reduced diameter section 310 is disposed within the through hole 210b, and a gap exists between the circumferential outer wall of the reduced diameter section 310 and the wall of the through hole 210b. The diameter of the reduced diameter section 310 is smaller than the diameter of the connecting section 320. The connecting member 300b passes through the through hole 210b of the front cover lock 200b, at least a portion of the reduced diameter section 310 is located within the through hole 210b, and the connecting section 320 can pass through the through hole 210b and is located outside the through hole 210b on the side of the front cover lock 200b closest to the fixing member 100. The connecting section 320 is connected to the fixing member 100 to secure the front cover lock 200b within the cabin. Since there is a gap between the circumferential outer wall of the reduced diameter section 310 and the wall of the through hole 210b, and the diameter of the reduced diameter section 310 is smaller than the diameter of the connecting section 320, the diameter of the part of the connecting piece 300b that mates with the through hole 210b is reduced, and the gap between the circumferential outer wall of the reduced diameter section 310 and the wall of the through hole 210b is increased.

[0066] When the structure and installation environment of the front cover lock 200b cannot be adjusted, this application reduces the diameter of the connecting part 300b that mates with the through hole 210b by making the diameter of the reduced diameter section 310 smaller than the diameter of the connecting section 320. This increases the gap between the circumferential outer wall of the reduced diameter section 310 and the hole wall of the through hole 210b, thereby increasing the installation adjustment range of the front cover lock 200b and the adjustment range of the distance between the front end of the front cover and the front end of the vehicle body, thus meeting the aesthetic requirements for matching the front end of the front cover with the front end of the vehicle body.

[0067] Furthermore, the diameter of the connecting section 320 is larger than that of the reduced diameter section 310. While increasing the gap between the circumferential outer wall of the reduced diameter section 310 and the hole wall of the through hole 210b, the connection strength between the connector 300b and the fastener 100 is still guaranteed, thus ensuring the stability of the connection.

[0068] The front hood lock mounting structure of this application embodiment provides a support platform for the front hood lock 200b when the structure and installation environment of the front hood lock 200b cannot be adjusted. The fastener 100 is installed inside the vehicle's engine compartment, allowing the front hood lock 200b to be mounted on the fastener 100. The front hood lock 200b has a through hole 210b through which a connector 300b passes. The connector 300b connects to the fastener 100, mounting the front hood lock 200b onto the fastener 100, thereby installing the front hood lock 200b inside the engine compartment. The connector 300b has a reduced diameter section 310 and a connecting section 320. The reduced diameter section 310 is located inside the through hole 210b, and there is a gap between the circumferential outer wall of the reduced diameter section 310 and the hole wall of the through hole 210b. The diameter of the reduced diameter section 310 is smaller than the diameter of the connecting section 320, which reduces the diameter of the portion of the connector 300b that mates with the through hole 210b. This increases the gap between the circumferential outer wall of the reduced diameter section 310 and the hole wall of the through hole 210b, thereby increasing the installation adjustment range of the front cover lock 200b within the through hole 210b along the vehicle height direction. Thus, with a fixed hole diameter and other factors, the installation height of the front cover lock 200b on the vehicle can be adjusted by moving the front cover lock 200b within the through hole 210b along the vehicle height direction. The current cover lock installation structure is applied to vehicles. After the front cover of the vehicle is installed on the engine compartment and locked with the front cover lock 200b, there is still a certain adjustment margin for the height difference between the front end of the front cover and the front end of the vehicle body. This increases the adjustment range of the height difference between the front end of the front cover and the front end of the vehicle body, so that the height difference between the front end of the front cover and the front end of the vehicle body can meet the design requirements of different vehicles, and thus meet the aesthetic requirements of matching the front end of the front cover with the front end of the vehicle body.

[0069] It should be noted that the requirements for the height difference design between the front end of the hood and the front end of the vehicle body vary depending on the vehicle model, and will not be elaborated further in this application.

[0070] Wherein, at least a portion of the reduced diameter section 310 is provided within the through hole 210b, meaning that the reduced diameter section 310 can be entirely provided within the through hole 210b, or a portion of the reduced diameter section 310 can be located within the through hole 210b, with the portion of the reduced diameter section 310 extending along the extension direction of the through hole 210b and connecting with the connecting section 320.

[0071] Furthermore, the connecting segment 320 is connected to the fixing member 100, and the connecting segment 320 passes through the fixing member 100. The connecting segment 320 may have threads, and the fixing member 100 may have threaded holes. The connecting segment 320 can be directly connected to the fixing member 100 through the threaded engagement with the threaded holes. Alternatively, the connecting segment 320 may pass through the fixing member 100 and be connected to the fixing member 100 by a locking member, such as a nut.

[0072] In some embodiments of this application, along the circumferential direction of the connector 300b, the gap between the circumferential outer wall of the reduced diameter section 310 and the hole wall of the through hole 210b is equal, thereby ensuring that the front cover lock 200b has the same range of adjustment in the upward movement direction X or the downward movement direction Y in the vehicle height direction.

[0073] In some embodiments of this application, the diameter of the reduced diameter section 310 is equal at various locations along the axial direction of the connector 300b. Exemplarily, the reduced diameter section 310 may be a cylindrical structure with the same diameter at each part, further ensuring that the gap between the circumferential outer wall of the reduced diameter section 310 and the wall of the through hole 210b is equal.

[0074] In some embodiments of this application, the reduced diameter section 310 is coaxially arranged with the through hole 210b. By sharing a central axis with the through hole 210b, the reduced diameter section 310 is centered in the through hole 210b, further ensuring that the gap between the circumferential outer wall of the reduced diameter section 310 and the hole wall of the through hole 210b is equal, so that the front cover lock 200b has the same range of adjustment in the upward movement direction X or the downward movement direction Y in the vehicle height direction.

[0075] In related technologies, the connector 300a is eccentrically positioned within the through hole 210a, resulting in varying gaps between the outer circumferential wall of the connector 300a and the wall of the through hole 210a. This can lead to a limitation in the adjustment range of the side with the smaller gap when adjusting the installation position of the front cover lock 200a. Therefore, by ensuring equal gaps between the outer circumferential wall of the reduced diameter section 310 and the wall of the through hole 210b, the adjustment range of the front cover lock 200b within the through hole 210b along the vehicle height direction is consistent, allowing for greater freedom of adjustment.

[0076] In some embodiments of this application, the difference between the diameter of the connecting section 320 and the diameter of the reduced diameter section 310 is the ratio of the diameter of the connecting section 320 to the diameter of the reduced diameter section 310, and the reduced diameter is greater than or equal to 20% and less than or equal to 25%.

[0077] For example, when the diameter of the through hole 210b is 10mm, the diameter of the part of the connector 300b that mates with the through hole 210b in the related technology is 8mm. The diameter of the reduced diameter section 310 provided in this application can be 6mm, so that the single-sided gap increases from 1mm to 2mm, and the connector 300b has a total adjustment space of 4mm in the vertical direction of the vehicle.

[0078] When the diameter of the through hole 210b is 12mm, the diameter of the part of the connector 300b that mates with the through hole 210b in the related technology is 10mm. The diameter of the reduced diameter section 310 provided in this application can be 8mm, so that the single-sided gap increases from 1mm to 2mm, and the connector 300b has a total adjustment space of 4mm in the vertical direction of the vehicle height.

[0079] When the reduction in diameter is greater than or equal to 20% and less than or equal to 25%, for example, the reduction in diameter can be 20%, 21%, 22%, 22.5%, 23%, 24%, and 25%, etc. This not only increases the gap between the circumferential outer wall of the reduction section 310 and the hole wall of the through hole 210b by reducing the diameter of the reduction section 310, thus improving the installation adjustment range of the front cover lock 200b in the through hole 210b along the vehicle height direction, but also ensures the rigidity and strength of the connector 300b, enabling it to provide a stable connection for the front cover lock 200b.

[0080] In some embodiments of this application, the connector 300b further has a fixed end 330 along its axial direction, located on the side of the reduced diameter section 310 opposite to the connecting section 320. The reduced diameter section 310, the fixed end 330, and the connecting end form an annular groove 340 in the circumferential direction of the connector 300b, and the circumferential outer wall of the reduced diameter section 310 forms the bottom wall of the annular groove 340. One end of the reduced diameter section 310 is connected to the connecting section 320, and the other end is connected to the fixed end 330. The diameter of the reduced diameter section 310 is smaller than that of the connecting section 320 and the fixed end 330.

[0081] The front cover lock 200b contacts the fixed end 330 on the side facing the reduced diameter section 310 to restrict the axial position of the connector 300b relative to the front cover lock 200b. For example, the fixed end 330 may be a flange.

[0082] Specifically, when the connector 300b passes through the through hole 210b, the connecting section 320 passes through the through hole 210b and connects with the fixing member 100. At least a portion of the reduced diameter section 310 is located within the through hole 210b and mates with it. The fixing end 330 is located on the side of the front cover lock 200b facing away from the fixing member 100, that is, the front cover lock 200b contacts the side of the fixing end 330 facing the reduced diameter section 310. The contact between the front cover lock 200b and the side of the fixing end 330 facing the reduced diameter section 310 creates a mechanical stop between the fixing member 100 and the side of the front cover lock 200b facing away from the fixing member 100, thereby preventing the connector 300b from axially disengaging from the through hole 210b and providing axial positioning and limiting for the connector 300b.

[0083] In some embodiments of this application, the reduced diameter section 310 is arc-shapedly connected to at least one of the connecting section 320 and the fixed end 330.

[0084] For example, the connection between the reduced diameter section 310 and the connecting section 320 adopts an arc-shaped connection. Along the axial extension direction of the connector 300b, the diameter of the end where the reduced diameter section 310 connects to the connecting section 320 gradually increases until it is the same as the diameter of the connecting section 320. Furthermore, the outer wall of the cross-section of the reduced diameter section 310 in the axial direction is arc-shaped, thus achieving an arc-shaped connection. By adopting an arc-shaped connection at the connection between the reduced diameter section 310 and the connecting section 320, stress concentration can be avoided, cracks can be prevented at the connection between the reduced diameter section 310 and the connecting section 320, and the impact resistance and fatigue life of the connector 300b can be enhanced.

[0085] Alternatively, the reduced diameter section 310 and the fixed end 330 can be connected in the same way. The reduced diameter section 310 can also be connected to the connecting section 320 and the fixed end 330 using an arc-shaped connection.

[0086] Furthermore, at least one of the reducing section and the connecting section 320 and the fixed end 330 can also be tapered. The axial cross-section of the reducing section 310 is tapered, and the tapered connection can also avoid stress concentration.

[0087] Based on this, this application also provides a front cover system. The system includes a front cover and a front cover locking mounting structure provided in any embodiment of this application.

[0088] The front cover is used to cover the engine compartment of a vehicle. The front cover has a front end and a rear end along its length. The rear end is used to connect to the vehicle body to open or close the engine compartment during movement. A front cover locking mounting structure is located inside the engine compartment and is opposite to and connected to the front end.

[0089] The structure of the front cover and the front cover lock mounting structure, as well as their connection with the vehicle body, have been described above and will not be repeated here.

[0090] The front hood system provided in this application, since including the front hood lock mounting structure provided in any embodiment of this application, has the same effect: when the front hood lock mounting structure is applied to a vehicle, and after the front hood is mounted on the engine compartment and locked with the front hood lock 200b, there is still a certain adjustment margin for the height difference between the front end of the front hood and the front end of the vehicle body. This increases the adjustment range of the height difference between the front end of the front hood and the front end of the vehicle body, so that the height difference between the front end of the front hood and the front end of the vehicle body can meet the design requirements of different vehicles, thereby satisfying the aesthetic requirements of matching the front end of the front hood with the front end of the vehicle body.

[0091] Furthermore, this application also provides a vehicle. The vehicle includes a body, an engine compartment, and a front hood system provided in any embodiment of this application. The front hood system has a front hood lock mounting structure located within the engine compartment and connected to the body. The front hood system is mounted on the engine compartment and movably connected to the body. The structures of the engine compartment and the front hood system have been described above and will not be repeated here.

[0092] This application provides a vehicle including a front hood system provided in any embodiment of this application. Since the system includes the front hood lock mounting structure provided in any embodiment of this application, it has the same effect. That is, when the front hood lock mounting structure is applied to the vehicle, and the front hood of the vehicle is mounted on the engine compartment and locked with the front hood lock 200b, the height difference between the front end of the front hood and the front end of the vehicle body still has a certain adjustment margin, thereby increasing the height difference adjustment range between the front end of the front hood and the front end of the vehicle body, so that the height difference between the front end of the front hood and the front end of the vehicle body can meet the design requirements of different vehicles, and thus meet the aesthetic requirements of matching the front end of the front hood with the front end of the vehicle body.

The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
