Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a hood and a vehicle. Background Technology

[0002] Currently, automatic emergency braking (AEB) is widely used in passenger cars. However, when AEB is applied, the front of the car often tilts downwards. This tilting motion causes the point of support for the pedestrian to shift downwards during a collision, increasing the impact intensity of the pedestrian's upper body hitting the hood and ultimately aggravating the pedestrian's collision injuries.

[0003] In existing technology, to prevent pedestrians from sustaining further injuries during a collision, a lifting device is typically installed inside the engine compartment. The principle is that after a collision, when the front of the vehicle tilts downwards, the lifting device explodes, raising the front of the engine hood a certain distance upon impact. This increases the point of impact support for pedestrians, reducing the intensity of the collision between the pedestrian and the engine hood, thus protecting the pedestrian.

[0004] However, conventional lifting devices usually require additional space in the cabin. Due to the compact layout of components in the cabin, reserving space for the installation of lifting devices will affect the normal arrangement of other structures in the cabin. Utility Model Content

[0005] In view of this, the present invention provides a hood and carrier to solve the problem that when arranging a lifting device, it is necessary to reserve installation space for the lifting device in the cabin, which affects the normal arrangement of other structures in the cabin.

[0006] In a first aspect, this application provides a hood, comprising: a hood body, a hood lock, and a lifting device. The hood lock is for engaging with a locking hook on a vehicle body; the lifting device has a first end and a second end, the first end and the second end being adapted to move in a relatively distant direction when the lifting device is activated, the first end being connected to the hood body, and the second end being connected to the hood lock.

[0007] Beneficial effects: By installing a lifting device between the hood lock and the hood body, no installation space needs to be reserved in the engine compartment, allowing other structures in the engine compartment to be arranged normally. Furthermore, when the lifting device is activated, the front of the hood can be raised relative to the vehicle body without separating the hood lock and the locking hook, protecting pedestrians while preventing damage to the hood lock and the locking hook.

[0008] In one alternative embodiment, the lifting device includes a lifting unit, with the first end and the second end being opposite ends of the lifting unit; a detonator is connected to the lifting unit and is used to introduce a detonating medium into the lifting unit.

[0009] Beneficial effects: The detonator and the lifting device are connected. By introducing the detonating medium into the lifting device through the detonator, the first and second ends of the lifting device can be moved away from each other. In addition, the introduction of the detonating medium enables the lifting device to quickly respond to the lifting of the cover, effectively protecting pedestrians.

[0010] In one optional embodiment, the lifting device includes a housing having an opening and including a bottom wall and side walls; a piston slidably disposed within the housing, dividing the housing into a first cavity near the bottom wall and a second cavity near the opening; the housing having a connecting hole communicating with the first cavity, and the detonator communicating with the connecting hole; and an end cap disposed at the opening; wherein the bottom wall forms a first end of the lifting device, and the end cap forms a second end of the lifting device.

[0011] Beneficial effects: The piston is slidably installed inside the housing. After the detonating medium of the detonator enters the first chamber, it pushes the piston to move axially along the housing. The piston drives the end cover, which can move rapidly relative to the housing, thereby enabling the cover to respond quickly and lift up, effectively protecting pedestrians.

[0012] In one alternative embodiment, a resilient pusher is further provided between the piston and the end cap.

[0013] Beneficial effects: The elastic pusher connects the piston and the end cap, allowing the piston to move along the housing and drive the end cap to move, achieving relatively synchronized displacement and improving the lifting response speed of the cover. Furthermore, in the event of a pedestrian collision with the cover, the elastic pusher, in conjunction with the piston's movement relative to the housing, absorbs impact energy, reducing rigid collisions and further protecting pedestrians.

[0014] In one optional embodiment, a first limiting structure and a second limiting structure are provided at intervals on the inner surface of the sidewall. The first limiting structure is used to limit the movement of the piston toward the opening, and the second limiting structure is used to limit the movement of the piston toward the bottom wall. The connecting hole is located between the second limiting structure and the bottom wall.

[0015] Beneficial effects: A first limiting structure is provided on the inner surface of the side wall to limit the piston. When the lifting device is activated, the first limiting structure blocks the piston, preventing it from detaching from the housing, thereby limiting the lifting height of the enclosure and protecting pedestrians. A second limiting structure is provided on the inner surface of the side wall to limit the piston. When the lifting device is not activated, a first cavity exists between the piston and the bottom wall, preventing the piston from blocking the connecting hole on the housing. This allows the detonator to deliver the detonating medium into the housing through the connecting hole, ensuring the normal operation of both the lifting device and the detonator.

[0016] In one alternative embodiment, the end cap includes a connecting plate and a positioning plate connected to each other, the positioning plate extending into the opening, the connecting plate being located axially outside the housing, the connecting plate being used to connect to the cover, and the cover further including a connecting structure for connecting the side wall and the positioning plate.

[0017] Beneficial effects: The positioning disc extends into the opening, achieving radial positioning through its cooperation with the housing. The connecting disc is located outside the housing and connects to the cover, providing an axial mounting reference surface for the end cover. Furthermore, the positioning disc and the connecting disc are connected by a connecting structure, which limits the end cover's position. When the lifting device is not activated, the end cover and housing remain relatively fixed. When the lifting device is activated, the limitation on the end cover is released, allowing the end cover to move relative to the housing. This ensures that the cover can connect to the vehicle body during normal use and can be lifted relative to the vehicle body after a collision with a pedestrian.

[0018] In one optional embodiment, a first connecting hole is provided on the side wall near the opening, and a second connecting hole is provided on the side surface of the positioning disk. The connecting structure includes a connecting pin, which passes through the first connecting hole and the second connecting hole.

[0019] Beneficial effects: The connecting pins connect the sidewall and the positioning plate, ensuring the connection strength between the shell and the positioning plate during normal use. Upon impact with a pedestrian, the connecting pins break under the action of the piston, allowing the end cap to easily lift the shell. Furthermore, the connecting pins are simple in structure, low in cost, and easy to replace, reducing the operating cost of the lifting device.

[0020] In one alternative embodiment, the hood lock includes a base having a first side close to the hood and a second side away from the hood, a first end of the lifting device being connected to the first side of the base; and a locking part being disposed on the second side of the base.

[0021] Beneficial effects: The lifting device and the locking mechanism are respectively located on both sides of the base. After the lifting device is activated, the connection between the locking mechanism and the locking hook on the vehicle body is not affected. Under the premise that the locking mechanism and the locking hook do not separate, pedestrians are protected while avoiding damage to the hood lock and the locking hook. In addition, the fact that the lifting device and the locking mechanism are respectively located on both sides of the base can also reduce the lateral area occupied, making the installation structure of the hood lock and the lifting device compact.

[0022] In an alternative embodiment, a decorative cover is further included, which is connected to the base, the latching portion passes through the decorative cover, and the decorative cover covers the base and the lifting device.

[0023] Beneficial effects: The decorative cover is used to cover the base and lifting device, protecting the lifting device from dust, moisture or oil stains, and the decorative cover can enhance the appearance of the machine cover lock.

[0024] Secondly, this application provides a vehicle including the aforementioned hood.

[0025] Beneficial effects: When mounted on a vehicle, the cover can be lifted upwards to protect pedestrians after a collision, reducing their impact injuries. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] The following is combined Figures 1 to 7 This describes an embodiment of the present application.

[0047] According to an embodiment of this application, in a first aspect, a hood is provided, including a hood body 1, a hood lock 2, and a lifting device 3. The hood lock 2 is used to cooperate with a locking hook on a vehicle body; the lifting device 3 has a first end 301 and a second end 302, the first end 301 and the second end 302 being adapted to move in a relatively distant direction when the lifting device 3 is activated, the first end 301 being connected to the hood body 1, and the second end 302 being connected to the hood lock 2.

[0048] In this embodiment, as Figure 1 As shown, the hood lock 2 is located at the front of the hood 1. The hood lock 2 and the locking hook on the vehicle body have a locked state and an unlocked state. In the locked state, the hood lock 2 and the locking hook are connected, so that the hood 1 and the vehicle body are connected and locked. In the unlocked state, the hood lock 2 is released from the connection with the locking hook, so that the hood 1 can be opened relative to the vehicle body.

[0049] The lifting device 3 is located between the hood lock 2 and the hood 1. When the vehicle is in normal use and does not collide with a pedestrian, the lifting device 3 serves as a connecting device to connect the hood 1 and the hood lock 2. After the vehicle collides with a pedestrian, the lifting device 3 is activated, and the first end 301 and the second end 302 of the lifting device 3 move away from each other. At this time, the hood lock 2 and the lock hook remain connected. Therefore, the second end 302 of the lifting device 3 is used as the fixed end, and the first end 301 is used as the movable end. The first end 301 is connected to the hood 1 to lift the hood 1.

[0050] Those skilled in the art will understand that the distance by which the cover 1 is lifted is the distance by which the first end 301 and the second end 302 of the lifting device 3 are relatively far apart from each other.

[0051] In this way, by setting a lifting device 3 between the hood lock 2 and the hood body 1, that is, integrating the lifting device 3 between the hood lock 2 and the hood body 1, no installation space needs to be reserved in the engine compartment for the lifting device 3, thus allowing other structures in the engine compartment to be arranged normally. Moreover, when the lifting device 3 is activated, the front part of the hood body 1 can be raised relative to the vehicle body without separating the hood lock 2 and the locking hook, protecting pedestrians while preventing damage to the hood lock 2 and the locking hook.

[0052] In one specific embodiment, a sensor and a controller (not shown in the figure) are installed on the vehicle body. The sensor is used to detect a collision between a pedestrian and the vehicle; the controller is communicatively connected to the sensor and the lifting device 3. After receiving pedestrian collision information from the sensor, the controller controls the lifting device 3 to lift the front of the cover 1. In this way, by using the sensor and controller in cooperation, the lifting device 3 can be self-activated after a pedestrian collision, shortening the response time of the lifting device 3 and reducing the risk of pedestrian injury.

[0053] Optionally, the hood provided in this application can be used on new energy vehicles, fuel vehicles, or hybrid vehicles. For new energy vehicles, the lifting device 3 is positioned between the hood body 1 and the hood lock 2, without occupying the engine compartment space at the front of the vehicle body used for accommodating structures such as motors. For fuel vehicles, the lifting device 3 is positioned between the hood body 1 and the hood lock 2, without occupying the engine compartment space at the front of the vehicle body used for accommodating structures such as engines.

[0054] In one embodiment, the lifting device 3 includes a lifting unit 31, with a first end 301 and a second end 302 being the two opposite ends of the lifting unit 31; an initiator 32 is connected to the lifting unit 31 and is used to introduce an initiating medium into the lifting unit 31.

[0055] In this embodiment, as Figure 1 , Figure 2As shown, the lifting device 31 is used to connect the cover 1 and the machine cover lock 2. The first end 301 of the lifting device 31 is connected to the cover 1, the second end 302 of the lifting device 31 is connected to the machine cover lock 2, and the detonator 32 is connected to the lifting device 31 to provide driving force for the movement of the first end 301 of the lifting device 31 relative to the second end 302.

[0056] The detonator 32 is preferably a gas-type detonator, which has the advantage of fast response speed. When the lifting device 3 is activated, the detonator 32 is activated, delivering the detonating medium into the lifting device 31. The detonating medium drives the first end 301 of the lifting device 31 to move, thereby enabling the lifting device 31 to quickly respond to lifting the cover 1. The detonating medium is preferably a high-pressure gas medium.

[0057] Specifically, such as Figure 6 As shown, the detonator 32 includes a detonator body 321, a detonating agent wiring harness 322, and an exhaust pipe 323. The detonator body 321 is filled with an initiating medium. The detonating agent wiring harness 322 is connected to the initiating medium and can be ignited under the control of the controller. When a pedestrian is hit, the controller sends a signal to the detonating agent wiring harness 322 and ignites it. The detonating agent wiring harness 322 ignites the initiating medium, which is then sent into the lifting device 31 through the exhaust pipe 323, thereby moving the first end 301 of the lifting device 31 to lift the cover 1.

[0058] Preferably, such as Figure 1 As shown, the detonator 32 is disposed outside the lifting device 31 and located on one side of the lifting device 31. The detonator 32 and the lifting device 31 are arranged side by side on the hood lock 2. In this way, with both the lifting device 31 and the detonator 32 arranged between the hood lock 2 and the hood 1, the axial length of the lifting device 31 is reduced, thereby reducing the axial space occupied by the lifting device 3 between the hood 1 and the hood lock 2, making the connection structure between the hood lock 2 and the hood 1 more compact.

[0059] Furthermore, such as Figure 1 As shown, a binding structure is provided around the outer periphery of the lifting device 31 and the detonator 32. The binding structure can be set as a clamp 8, which is used to fix the detonator 32 to the outer wall of the lifting device 31. In this way, the lifting device 31 and the detonator 32 are relatively fixed, which facilitates the installation of the detonator 32.

[0060] Optionally, in addition to the gas-type detonator described above, the detonator 32 can also be configured as an electromagnetic detonator. When the lifting device 3 is activated, the detonator 32 is energized, and the first end 301 of the lifting device 31 can move under energization to lift the cover 1.

[0061] Of course, in addition to the above-mentioned configuration, the detonator 32 can also be other types of detonation devices. After colliding with a pedestrian, the detonator 32 can enable the first end 301 of the lifting device 31 to move quickly in response.

[0062] In one embodiment, the lifting device 31 includes a housing 311, a piston 312, and an end cap 316. The housing 311 has an opening and includes a bottom wall 3111 and a side wall 3112. The piston 312 is slidably disposed within the housing 311, dividing the housing 311 into a first cavity 313 near the bottom wall 3111 and a second cavity 314 near the opening. A connecting hole 315 is provided on the housing 311, communicating with the first cavity 313, and the detonator 32 communicates with the connecting hole 315. The end cap 316 is disposed at the opening. Further, the bottom wall 3111 forms a first end 301 of the lifting device 31, and the end cap 316 forms a second end 302 of the lifting device 31.

[0063] In this embodiment, as Figure 3 As shown, the housing 311 has a bottom wall 3111 and a side wall 3112. The bottom wall 3111 is connected to the hood lock 2, so that the housing 311 is fixed on the hood lock 2. The end cover 316 is connected to the cover 1. Driving the end cover 316 to move upward relative to the housing 311 can drive the cover 1 to rise. A piston 312 is provided inside the housing 311. The piston 312 is limited by the side wall 3112, so that the piston 312 slides along the side wall 3112 and can maintain a general seal between the piston 312 and the side wall 3112, preventing the gas medium entering the first cavity 313 from passing through the gap between the piston 312 and the side wall 3112 and affecting the driving effect of the piston 312 on the end cover 316.

[0064] Among them, such as Figure 3 As shown, a connecting hole 315 is provided on the housing 311. The connecting hole 315 is provided on the bottom wall 3111 and / or the side wall 3112 of the housing 311. The connecting hole 315 is preferably provided on the side wall 3112 so that the connecting hole 315 can be connected to the exhaust pipe 323 of the detonator 32.

[0065] Under the above configuration, after the detonator 32 is activated, the detonating medium of the detonator 32 enters the first cavity 313 and pushes the piston 312 to move upward along the axial direction of the housing 311. The piston 312 drives the end cover 316, so that the end cover 316 can move rapidly relative to the housing 311, thereby causing the cover 1 to respond quickly and rise, effectively protecting pedestrians.

[0066] In one embodiment, a resilient pusher 317 is also provided between the piston 312 and the end cap 316.

[0067] In this embodiment, as Figure 3 , Figure 4 As shown, the elastic pusher 317 is used to connect the piston 312 and the end cap 316, so that when the piston 312 moves along the housing 311, it can drive the end cap 316 to move through the elastic pusher 317, so that the two can achieve relatively synchronous displacement and improve the response speed of the end cap 316.

[0068] The elastic pusher 317 is preferably a spring, with its two ends fixed to the piston 312 and the end cap 316, respectively. When the lifting device 3 is not activated, the end cap 316 compresses the spring, keeping it in a compressed state. Thus, after the detonator 32 is detonated, the elastic pusher 317 releases from its compressed state, pushing the end cap 316 relative to the housing 311, further increasing the ejection speed of the end cap 316, thereby further increasing the lifting speed of the housing 1, enabling the housing 1 to quickly respond to the lifting action and protect pedestrians.

[0069] In addition, after the cover 1 is lifted and the pedestrian collides with the cover 1, the elastic pusher 317 and piston 312 are compressed and retracted under the impact of the pedestrian's upper torso, which absorbs energy and protects the pedestrian's upper torso and head from the impact, further reducing the damage to the pedestrian.

[0070] In some embodiments not shown, the spring may be omitted, and the gas in the second chamber 314 may be rapidly compressed after the piston moves, using the high-pressure gas to drive the end cap 316 to move, thereby lifting the cover 1. However, in this embodiment, it cannot provide further cushioning after a collision (because there is no spring).

[0071] In one embodiment, a first limiting structure 4 and a second limiting structure 5 are provided at intervals on the inner surface of the sidewall 3112. The first limiting structure 4 is used to limit the movement of the piston 312 toward the opening, and the second limiting structure 5 is used to limit the movement of the piston 312 toward the bottom wall 3111. The connecting hole 315 is located between the second limiting structure 5 and the bottom wall 3111.

[0072] In this embodiment, as Figure 3 As shown, a first limiting structure 4 is provided on the inner surface of the side wall 3112 near the opening. The first limiting structure 4 is used to limit the piston 312, so that when the lifting device 31 is activated, the first limiting structure 4 blocks the piston 312, preventing the piston 312 from separating from the housing 311 and preventing the spring from losing its buffering effect.

[0073] Meanwhile, by changing the position of the first limiting structure 4 on the side wall 3112, the rising height of the cover 1 after the collision can be changed to better protect pedestrians.

[0074] Optionally, the first limiting structure 4 is configured as one or more combinations of a protruding post, protruding ring, or protrusion protruding from the inner surface of the sidewall 3112. For example, the first limiting structure 4 is configured as a protruding post, which can be a pin passing through the sidewall 3112, with one end disposed inside the housing 311 and the other end disposed outside the housing 311. The portion of the pin disposed inside the housing 311 restricts the piston 312 from continuing to move toward the opening of the housing 311. When the first limiting structure 4 is configured as a combination of multiple protruding posts, protruding rings, or protrusions, the end face of the combined structure closest to the piston 312 is preferably flush with the piston to synchronously limit the movement of the piston 312 toward the opening.

[0075] Optionally, multiple first limiting structures 4 can be provided, with multiple first limiting structures 4 located at the same height of the side wall 3112 and distributed at intervals along the circumference. By providing multiple first limiting structures 4, multiple points of the piston 312 can be limited, while also being able to withstand greater impact forces and prevent the piston 312 from dislodging from the housing 311.

[0076] In this embodiment, a second limiting structure 5 is provided on the inner surface of the side wall 3112 near the bottom wall 3111. The second limiting structure 5 is used to limit the piston 312. When an elastic pusher 317 is provided between the end cap 316 and the piston 312, the second limiting structure 5 limits the piston 312, which keeps the elastic pusher 317 in a compressed state. At the same time, in the unactivated state of the lifting device 3, there is a first cavity 313 between the piston 312 and the bottom wall 3111, which prevents the piston 312 from blocking the connecting hole 315 on the housing 311. This allows the detonator 32 to send the detonating medium into the housing 311 through the connecting hole 315. The detonating medium pushes the piston 312 to move along the housing 311, so that both the lifting device 31 and the detonator 32 can operate normally.

[0077] Optionally, the second limiting structure 5 is configured as one or more combinations of a protruding post, a protruding ring, or a protrusion protruding from the inner surface of the sidewall 3112. For example, the second limiting structure 5 is configured as a protruding ring, which protrudes from the surface of the sidewall 3112 and forms a stepped surface, allowing a portion of the piston 312 to overlap the stepped surface, thus restricting the piston 312 from moving towards the bottom wall 3111. Furthermore, when the first limiting structure 4 is configured as a combination of multiple protruding posts, protruding rings, or protrusions, the end face of the combined structure closest to the piston 312 is preferably flush with the piston to synchronously limit the movement of the piston 312 towards the bottom wall 3111.

[0078] In one embodiment, the end cap 316 includes a connecting plate 3161 and a positioning plate 3162 connected to each other. The positioning plate 3162 extends into the opening, and the connecting plate 3161 is located on the axial outer side of the housing 311. The connecting plate 3161 is used to connect with the cover 1. The cover also includes a connecting structure for connecting the side wall 3112 and the positioning plate 3162.

[0079] In this embodiment, from Figure 3 and Figure 4 As can be seen, the outer diameter of the positioning disk 3162 is smaller than the outer diameter of the connecting disk 3161. The outer diameter of the positioning disk 3162 is adapted to the inner diameter of the opening (slightly smaller), so the positioning disk 3162 can be inserted into the housing 311. The outer diameter of the connecting disk 3161 is larger than the inner diameter of the opening, so the connecting disk 3161 is limited to the axial outer side of the housing 311.

[0080] In this embodiment, as Figure 3 , Figure 4 As shown, the outer peripheral wall of the positioning disk 3162 and the side wall 3112 of the housing 311 are slidably fitted. The top of the positioning disk 3162 is fixed with a connecting disk 3161. The connecting disk 3161 provides an axial mounting reference surface for the end cover 316. The connecting disk 3161 is preferably connected to the reinforcing beam on the cover 1 to improve the connection strength between the end cover 316 and the cover 1.

[0081] The connecting disc 3161 and the cover 1 can be one or more combinations of fastener connection, welding or bonding.

[0082] A connecting structure is provided between the positioning disk 3162 and the side wall 3112. When the lifting device 31 is not activated, the connecting structure is used to restrict the movement of the positioning disk 3162 relative to the side wall 3112, thereby restricting the movement of the end cover 316 relative to the housing 311 and preventing the end cover 316 from lifting the cover 1. At this time, the function of the connecting structure is to normally connect the cover lock 2 and the cover 1.

[0083] After the lifting device 31 is activated, the end cover 316 is driven by the piston 312 through the elastic pusher 317. This driving force is greater than the strength of the connecting structure itself, causing the connecting structure to be destroyed and releasing the restriction on the end cover 316, thereby realizing the movement of the end cover 316 relative to the housing 311 and lifting the cover 1.

[0084] In one embodiment, a first connecting hole 318 is provided on the side wall 3112 near the opening, and a second connecting hole 319 is provided on the side surface of the positioning disk 3162. The connecting structure includes a connecting pin 6, which passes through the first connecting hole 318 and the second connecting hole 319.

[0085] In this embodiment, as Figure 3 , Figure 5As shown, the preferred connection structure is a connecting pin 6, with one end of the connecting pin 6 passing through a first connecting hole 318 on the side wall 3112 and extending into a second connecting hole 319 on the positioning disk 3162. When the lifter 31 is not activated, the connecting pin 6 connects the side wall 3112 and the positioning disk 3162, ensuring the connection strength between the housing 311 and the positioning disk 3162 during normal use. After the lifter 31 is activated, the piston 312 applies a driving force to the end cover 316 via the elastic pusher 317. This driving force is greater than the strength of the connecting pin 6 itself, causing the connecting pin 6 to break and release the end cover 316. Using the connecting pin 6 to connect the side wall 3112 and the positioning disk 3162 results in a simple structure, low cost, and easy replacement, reducing the operating cost of the lifting device 3.

[0086] Preferably, multiple connecting pins 6 are provided and evenly arranged circumferentially along the side wall 3112. In this way, the connection strength between the side wall 3112 and the positioning plate 3162 can be improved by using multiple connecting pins 6.

[0087] In one embodiment, the hood lock 2 includes a base 21 having a first side close to the hood 1 and a second side away from the hood 1, the first end 301 of the lifting device 3 being connected to the first side of the base 21; and a latch 22 being disposed on the second side of the base 21.

[0088] In this embodiment, as Figure 1 As shown, the base 21 has a first side and a second side facing each other. The lifting device 3 and the locking part 22 are respectively arranged on both sides of the base 21. After the lifting device 3 is activated, the connection between the locking part 22 and the locking hook part on the vehicle body is not affected. Under the premise that the locking part 22 and the locking hook part are not separated, pedestrians are protected while avoiding damage to the hood lock 2 and the locking hook part. Moreover, the lifting device 3 and the locking part 22 are respectively arranged on both sides of the base 21, which can also reduce the lateral area occupied, making the installation structure of the hood lock 2 and the lifting device 3 more compact.

[0089] Understandably, the latch 22 on the engine hood lock 2 is usually set as a U-shaped structure, and the hook part on the vehicle body is usually set as a hook-shaped structure. The U-shaped structure and the hook-shaped structure work together to connect the latch 22 and the hook part.

[0090] Furthermore, such as Figure 7 As shown, the base 21 is also provided with at least one first mounting hole 23 and multiple second mounting holes 24. A mounting bolt 25 passes through the first mounting hole 23, and the locking part 22 is fixed to the surface of the base 21 by the mounting bolt 25.

[0091] Preferably, such as Figure 2 , Figure 3As shown, bolt holes 320 are provided on the bottom wall 3111. One end of the mounting bolt 25 passes through the first mounting hole 23 and extends into the bolt hole 320. In this way, the locking part 22 and the lifting device 31 are fixed to the base 21 by the mounting bolt 25, which facilitates the assembly of the locking part 22 and the lifting device 31 with the base 21.

[0092] In one embodiment, a decorative cover 7 is also included, which is connected to the base 21, with a latch 22 passing through the decorative cover 7, and the decorative cover 7 covers the base 21 and the lifting device 3.

[0093] In this embodiment, as Figure 1 , Figure 2 As shown, the decorative cover 7 is provided with a fixing hole that matches the second mounting hole 24. By inserting bolts into the fixing hole and the second mounting hole 24, the decorative cover 7 is fixed to the base 21. The end of the decorative cover away from the base 21 is preferably in contact with the cover body 1. The decorative cover 7 is used to cover the base 21 and the lifting device 3, protect the lifting device 3, and prevent dust, water vapor or oil stains from contacting the lifting device 3. In addition, the setting of the decorative cover 7 makes the lifting device invisible to the user, improves the aesthetics of the cover lock 2, and can also prevent the explosive structure from being accidentally triggered.

[0094] Secondly, this application provides a vehicle including the aforementioned hood.

[0095] Alternatively, the vehicle may be a vehicle or a low-altitude aircraft.

[0096] Alternatively, the vehicle can be a gasoline-powered car or a new energy electric vehicle.

[0097] In this embodiment, the cover is mounted on the vehicle. After a collision with a pedestrian, the cover can be lifted upwards to protect the pedestrian and reduce the pedestrian's collision damage.

[0098] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
