Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to the front engine compartment structure of a vehicle and the vehicle itself. Background Technology

[0002] In daily vehicle use, vehicles may fall into water. After a vehicle falls into water, the front engine compartment, being heavier, may gradually sink into the water, causing water to enter the passenger compartment and posing a danger to the occupants.

[0003] In the prior art, there is a car submersion alarm device, which includes a car body and a pressure sensor on the car body. The pressure sensor is connected to the on-board computer and can sound an alarm after the car has been submerged in water, so as to call for help from the outside world.

[0004] However, while calling the emergency alarm after a vehicle falls into water can call for rescue immediately, it is difficult to slow down the vehicle's sinking speed, which can endanger the lives of the people inside the vehicle before rescue arrives. Utility Model Content

[0005] This utility model provides a front engine compartment structure and a vehicle to solve the problem of how to slow down the sinking speed of a vehicle after it falls into water. To achieve the above objective, the technical solution adopted by this utility model is as follows:

[0006] In a first aspect, this application provides a front engine compartment structure for a vehicle, including an engine compartment body, an engine compartment side beam, and an airbag. The engine compartment body has a receiving cavity; the engine compartment side beam is located in the receiving cavity and is connected to one end of the engine compartment body away from the passenger compartment of the vehicle; the airbag is connected to the lower side of the engine compartment side beam.

[0007] Based on the aforementioned technical means, by installing a side beam within the cabin's accommodating cavity and placing an airbag beneath the side beam, the side beam can support the airbag. Even after the vehicle falls into water, and the pressure difference between the inside and outside of the vehicle causes water to rapidly flood the interior, the airbag can provide buoyancy to prevent the vehicle from sinking quickly, thus providing more rescue time for the occupants and improving their safety. In the event of a collision, the airbag can also be inflated to absorb impact energy, cushioning and protecting components and occupants within the front cabin structure, reducing injury to these components and occupants.

[0008] In one possible implementation, the forward cabin structure further includes a connecting mechanism connected to the cabin side beam, and the airbag is connected to the connecting mechanism.

[0009] Based on the aforementioned technical means, the connecting mechanism connects both the airbag and the cabin side beam, ensuring the long-term reliability of the connection between the airbag and the cabin side beam. Through the design of the connecting mechanism, the airbag can be first connected to the connecting mechanism, and then the connecting mechanism can be fixed to the cabin side beam, facilitating the connection between the airbag and the cabin side beam.

[0010] In one possible implementation, the connecting mechanism includes a first connecting beam and a second connecting beam, which are spaced apart along the length of the vehicle; both the first connecting beam and the second connecting beam are connected between the airbag and the engine compartment side beam.

[0011] According to the above technical means, the first connecting beam and the second connecting beam are arranged at intervals along the length direction of the vehicle, which can fix and support the two ends of the airbag in the length direction of the vehicle, thereby improving the stability of the airbag support. In addition, after the airbag is inflated, it can ensure that the airbag has a certain thickness in the length direction of the vehicle, thus ensuring the cushioning performance of the airbag.

[0012] In one possible implementation, the forward cabin structure also includes an air pump located within a housing cavity and connected to the airbag for inflating the airbag.

[0013] Based on the aforementioned technical means, the containment cavity provides the air pump with a relatively independent and enclosed space, effectively isolating it from dust, oil, moisture, and other impurities in the forward engine compartment. This prevents these substances from entering the air pump and affecting the normal operation of its mechanical components and electrical system, reducing the probability of air pump malfunction due to contamination. The direct connection between the air pump and the airbag shortens the gas transmission path, reducing gas leakage and pressure loss during delivery.

[0014] In one possible implementation, the air pump is located on the side of the airbag closest to the passenger compartment of the vehicle.

[0015] Based on the aforementioned technical means, the air pump is positioned closer to the passenger compartment, effectively utilizing the vehicle's interior space. Compared to placing the air pump on the side of the airbag away from the passenger compartment, placing the air pump closer to the passenger compartment during a collision avoids damage to the air pump, preventing the airbag from inflating. Furthermore, after the airbag inflates, it can also cushion and protect the air pump, preventing damage to it.

[0016] In one possible implementation, the cabin body includes a bottom protective plate, airbags and cabin side beams are located above the bottom protective plate, and the airbags are spaced apart from the bottom protective plate.

[0017] Based on the aforementioned technical means, the airbag is located above and spaced apart from the bottom protective plate. This prevents the bottom protective plate from directly compressing, colliding with, or wearing down the airbag when the vehicle comes into contact with ground debris, stones, or road impacts during driving. The spaced arrangement between the airbag and the bottom protective plate provides sufficient space underneath the airbag, allowing it to fully inflate and improve its cushioning effect, as well as the buoyancy it provides to the vehicle body when it falls into water. The airbag inflates downwards, into the space between the airbag and the bottom protective plate, reducing the space it occupies in the longitudinal direction and facilitating the arrangement of other components in the engine compartment.

[0018] In one possible implementation, the front engine compartment structure also includes a front collision beam and collision sensors. The front collision beam is connected to the engine compartment body and is located on the side of the vehicle where the airbag faces away from the passenger compartment; the collision sensors are connected to the front collision beam and are used to detect collision signals from the vehicle.

[0019] Based on the aforementioned technical means, when a vehicle collision occurs, the obstacle typically impacts the front collision beam, which can initially absorb the collision energy. Collision sensors are directly connected to the front collision beam, detecting physical changes during a collision and transmitting signals promptly. These sensors ensure timely monitoring before a collision, facilitating rapid airbag inflation and ensuring the safety of the occupants.

[0020] In one possible implementation, the forward cabin structure also includes straps and buckles, with the female buckle of the buckle connected to one end of the strap and the male buckle of the buckle connected to the other end of the strap; the airbag has an uninflated state and an inflated state, when the airbag is in the uninflated state, the straps bind the airbag and the male buckle is inserted into the female buckle; when the airbag is in the inflated state, the male buckle is disengaged from the female buckle.

[0021] According to the aforementioned technical means, when the airbag is in an uninflated state, the straps secure it by interlocking male and female buckles. This firmly restrains the folded airbag in a predetermined position within the forward cabin structure, ensuring its stability when not in operation. When the airbag needs to inflate and deploy, the male and female buckles disengage, allowing for a quick and smooth inflation process and deployment to the predetermined shape, thus providing timely protection.

[0022] Secondly, this application also provides a vehicle that includes the front engine compartment structure described in any of the first aspects.

[0023] Since the vehicle provided in this application includes a front engine compartment structure as described in any of the above embodiments, both can solve the same technical problem and achieve the same effect.

[0024] In one possible implementation, the vehicle further includes a wading detection device for detecting the wading depth of the vehicle; and / or a visual detection device for detecting the wading status of the vehicle.

[0025] Based on the aforementioned technologies, the wading detection device can detect the amount and pressure of water around a vehicle and transmit signals promptly. The visual detection device uses cameras and other equipment to capture the wading situation around the vehicle and transmit signals promptly. The combination of the wading detection device and the visual detection device ensures timely monitoring when a vehicle encounters a wading hazard. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0034] With the development of the automotive industry, vehicles have become widely used. Vehicles can be categorized into new energy vehicles and traditional gasoline-powered vehicles. Traditional gasoline-powered vehicles use fossil fuels such as gasoline and diesel as power sources. They generate heat energy by burning fuel in an internal combustion engine, which is then converted into mechanical energy to drive the vehicle. The entire process relies on the combustion reaction of the fuel. New energy vehicles, on the other hand, rely on the electrical energy stored in batteries, which is then converted into mechanical energy by an electric motor to drive the wheels, eliminating the need for fuel combustion.

[0035] The vehicle used in this embodiment is a new energy vehicle. However, the vehicle in this embodiment can also be of different types. For example, the vehicle provided in this embodiment can be a sedan, a sportutility vehicle (SUV), or a multi-purpose vehicle (MPV), etc.

[0036] In some embodiments, see Figure 1 The vehicle in this application includes a vehicle body 10 and a front engine compartment structure 13 mounted on the vehicle body 10. The front engine compartment structure 13 is located in front of the passenger compartment, providing installation and protection space for the core components at the front of the vehicle, reducing the corrosion of internal components by external dust, moisture, and debris, and protecting them from direct impacts from bumps and collisions during driving, thus ensuring the stable operation of various systems. These core components may include motors, battery packs, and wiring. The passenger compartment provides seating space for the driver and passengers.

[0037] In some embodiments, see Figure 1 The vehicle also includes a wading detection device 11, which is used to detect the wading depth of the vehicle.

[0038] Based on this, the wading detection device 11 can detect the amount and pressure of water around the vehicle and transmit signals in a timely manner. This wading detection device ensures timely monitoring when a vehicle encounters a wading hazard.

[0039] For example, the water wading detection device 11 can be a water level pressure sensor. When the vehicle is wading through water, the water level pressure sensor can directly contact the water, detect the water pressure signal, and upload the pressure signal to the central processing unit, which then determines the water depth data.

[0040] Another example is that the wading detection device 11 can be a water level conductive sensor. When the vehicle is wading, the sensor can directly contact the water and determine the water depth by sensing the conductivity of the water. The water level conductive sensor uses the conductivity of water to trigger the corresponding electrical signal when the water level reaches different electrode positions. The electrical signal is then uploaded to the central processing unit, which determines the water depth data.

[0041] Based on this, in some examples, the wading detection device 11 can be installed at the lower end of the vehicle body, such as near the door sill. The number of wading detection devices 11 can be one or more, and when there are multiple wading detection devices 11, the multiple wading detection devices 11 can be arranged at intervals around the vehicle body.

[0042] In other examples, the wading detection device 11 may also be installed in other locations on the vehicle body, such as the bottom of the vehicle body. This application does not specifically limit this.

[0043] In some embodiments, see Figure 1 The vehicle also includes a vision detection device 12, which is used to detect the vehicle's wading conditions.

[0044] Based on this, the visual inspection device 12 can capture the environment around the vehicle to determine whether the vehicle is in a water-crossing environment, thereby detecting the vehicle's water-crossing status. The visual inspection device ensures timely monitoring when the vehicle encounters a water-crossing hazard.

[0045] For example, the visual detection device 12 includes a high-definition camera mounted on the vehicle. The high-definition camera captures image information of the road surface ahead in real time, including visual features of the water accumulation area, such as the reflective effect of the water surface, the boundary contours between the water and surrounding objects, and dynamic features such as ripples and floating objects that may appear in the water area. The image information is uploaded to a central processing unit, which determines whether the vehicle body is in deep water.

[0046] In some examples, the vision sensor 12 can be mounted on the vehicle's rearview mirror; in other examples, the vision sensor 12 can be mounted in other locations on the vehicle, such as the side panel, etc. The number of vision sensors 12 can be one or more.

[0047] In other embodiments, please refer to Figure 1The vehicle also includes a wading detection device 11 and a vision detection device 12. The wading detection device 11 is used to detect the wading depth of the vehicle; the vision detection device 12 is used to detect the wading status of the vehicle.

[0048] Based on this, the vehicle includes both a water wading detection device 11 and a visual detection device 12, which can simultaneously achieve the effect of the above two embodiments, namely, the vehicle includes both a water wading detection device 11 and a visual detection device 12.

[0049] Based on this, the installation height of the water wading detection device 11 can be 100mm to 150mm (such as 100mm, 125mm, 150mm, etc.) above the bottom of the vehicle body to ensure accurate detection of water wading conditions, where the bottom refers to the upper surface of the vehicle body floor.

[0050] In another example, the wading detection device 11 is normally in a dormant state. The wading detection device 11 is connected to a float button, which is activated when the float button is double-clicked. The float button can be located on the vehicle's dashboard, allowing the driver to quickly press it in case of danger.

[0051] Based on this, the floating button is an operating component that can be double-clicked to activate the connected water wading detection device 11, switching the device from a dormant state to a working state, thereby starting the monitoring of the vehicle's water wading status.

[0052] When the vehicle is driving normally and is not at risk of wading, the water-floating button is in standby mode, its circuit maintains a low-power mode and does not actively trigger any commands. At this time, the water wading detection device 11 connected to it is in a dormant state, only maintaining basic circuit connections and not performing real-time detection to reduce vehicle energy consumption.

[0053] When a driver anticipates a potential water wading scenario or perceives a water wading hazard, they can double-click the water wading detection button on the dashboard. The button contains a contact switch, which closes upon two consecutive presses, generating an electrical signal. This signal is rapidly transmitted via a wire to the controller of the water wading detection device 11, serving as an activation command to break the device's dormant state.

[0054] Please see Figure 1 and combined Figure 2 This application provides a front engine compartment structure 13 for a vehicle. The front engine compartment structure 13 includes an engine compartment body 100, an engine compartment side beam 200, and an airbag 300. The engine compartment body 100 has a receiving cavity 101. The engine compartment side beam 200 is disposed in the receiving cavity 101 and connected to the end of the engine compartment body 100 away from the passenger compartment of the vehicle. The airbag 300 is connected to the lower side of the engine compartment side beam 200.

[0055] Based on this, by installing a cabin side beam 200 within the receiving cavity 101 of the cabin body 100, and installing an airbag 300 on the lower side of the cabin side beam 200, the cabin side beam 200 can support the airbag 300. After the vehicle falls into water, even if the pressure difference between the inside and outside of the vehicle causes water to rush into the vehicle quickly, the airbag 300 can still provide buoyancy to the vehicle to prevent it from sinking rapidly, providing more rescue time for the occupants in the passenger compartment and improving their safety.

[0056] When a vehicle collision occurs, the airbag 300 can be inflated to absorb collision energy and buffer and protect the components and occupants inside the front engine compartment structure 13, reducing the damage to the components and occupants inside the front engine compartment structure 13.

[0057] In some embodiments, see Figure 2 The forward cabin structure 13 also includes a connecting mechanism 400, which is connected to the cabin side beam 200, and the airbag 300 is connected to the connecting mechanism 400.

[0058] Based on this, the connecting mechanism 400 connects both the airbag 300 and the cabin side beam 200, ensuring the long-term reliability of the connection between the airbag 300 and the cabin side beam 200. Through the connecting mechanism 400, the airbag 300 can be first connected to the connecting mechanism 400, and then the connecting mechanism 400 can be fixed to the cabin side beam 200, facilitating the connection between the airbag 300 and the cabin side beam 200.

[0059] For example, the connecting mechanism 400 can be connected to the cabin side beam 200 by bolts or snap-fit, ensuring the stability of the connection between the connecting mechanism 400 and the cabin side beam 200.

[0060] The airbag 300 can be connected to the connecting mechanism 400 by means of strapping or adhesive connection.

[0061] In some embodiments, see Figure 2 The connecting mechanism 400 includes a first connecting beam 401 and a second connecting beam 402, which are spaced apart along the length of the vehicle; both the first connecting beam 401 and the second connecting beam 402 are connected between the airbag 300 and the engine compartment side beam 200.

[0062] Based on this, the first connecting beam 401 and the second connecting beam 402 are spaced apart along the length of the vehicle, which can fix and support the two ends of the airbag 300 in the length of the vehicle, thereby improving the stability of the support for the airbag 300. Furthermore, after the airbag 300 is inflated, it can ensure that the airbag 300 has a certain thickness in the length of the vehicle, thus ensuring the cushioning performance of the airbag 300.

[0063] It should be noted that the first connecting beam 401 and the second connecting beam 402 can be flexibly adjusted in length, angle or connection point position according to the size and shape of the airbag 300 and the structural characteristics of the cabin side beam 200, providing more flexible installation and adjustment space for the airbag 300.

[0064] In some embodiments, see Figure 1 and combined Figure 2 The forward cabin structure 13 also includes an air pump 500, which is located in the receiving cavity 101 and connected to the airbag 300 for inflating the airbag 300.

[0065] Based on this, the receiving cavity 101 provides a relatively independent and enclosed space for the air pump 500, which can effectively isolate dust, oil, water vapor and other impurities in the front engine compartment, preventing these substances from entering the air pump 500 and affecting the normal operation of its mechanical components and electrical system, thus reducing the probability of the air pump 500 malfunctioning due to contamination. The air pump 500 is directly connected to the air bag 300, shortening the gas transmission path and reducing gas leakage and pressure loss during the delivery process.

[0066] For example, the air pump 500 can inflate the airbag 300 through an air delivery tube. One end of the air delivery tube is connected to the air outlet of the air pump 500, and the other end is connected to the air inlet of the airbag 300, forming a closed gas delivery channel. When the air pump 500 is started, its internal pump structure generates pressure, compressing the air and delivering it to the airbag 300 through the air delivery tube, thus changing the airbag 300 from an uninflated state to an inflated state. The uninflated state means that the airbag 300 contains almost no air, and in this state, the airbag 300 can be folded or contracted. The inflated state means that the airbag 300 unfolds from the folded state into a structure with a certain shape, containing air inside.

[0067] In another example, the air pump 500 has an air pump control device, such as an air pump controller, that receives signals from the central processing unit. The air pump control device can control whether the air pump 500 is started. If the central processing unit detects that the vehicle is in danger, it sends a command to the air pump control device to start the air pump 500. Upon receiving the signal, the air pump control device controls the air pump 500 to start and inflate the airbag 300.

[0068] In some embodiments, see Figure 2The air pump 500 is located on the side of the airbag 300 near the passenger compartment of the vehicle.

[0069] Based on this, the air pump 500 is located closer to the passenger compartment, effectively utilizing the vehicle's interior space. Compared to the airbag 300 being located on the side away from the passenger compartment, placing the air pump 500 closer to the passenger compartment during a collision avoids damage to the air pump 500, preventing the airbag 300 from inflating. Furthermore, the inflated airbag 300 can cushion and protect the air pump 500, preventing its damage.

[0070] In some examples, the air pump 500 is mounted on the front subframe of the vehicle. The front subframe provides better support for the air pump 500.

[0071] In some embodiments, see Figure 2 The cabin body 100 includes a bottom protective plate 102, an airbag 300 and a cabin side beam 200 located on the upper side of the bottom protective plate 102, and the airbag 300 is spaced apart from the bottom protective plate 102.

[0072] For example, the cabin body 100 also includes a front bulkhead, front fenders, and a cabin top cover. The front bulkhead, front fenders, cabin top cover, and bottom protective plate 102 together constitute a closed or semi-closed cabin space. The bottom edge of the front bulkhead is connected to the end of the bottom protective plate 102 near the passenger compartment. There are two front fenders, which are symmetrically distributed on both sides of the vehicle's width direction and located above the bottom protective plate 102, extending outward along the vehicle's width direction. The front and rear ends of the cabin top cover are connected to the top of the front bulkhead, and the sides overlap with the front fenders.

[0073] Based on this, the airbag 300 is located on the upper side of the bottom protective plate 102, which can prevent the bottom protective plate 102 from directly squeezing, colliding or wearing the airbag 300 when it comes into contact with ground debris, stones or road impacts during vehicle operation.

[0074] The airbag 300 and the bottom protective plate 102 are spaced apart, which can provide enough space under the airbag 300 so that the airbag 300 can fully expand after inflation, thereby improving the cushioning effect of the airbag 300 and the buoyancy provided to the vehicle body when it falls into the water.

[0075] The airbag 300 inflates downwards, that is, into the space between the airbag 300 and the bottom protective plate 102, which can reduce the space occupied in the length direction and facilitate the arrangement of other components in the cabin.

[0076] In some embodiments, see Figure 2The front engine compartment structure 13 also includes a front collision beam 600 and a collision sensor 700. The front collision beam 600 is connected to the engine compartment body 100 and is located on the side of the airbag 300 facing away from the passenger compartment of the vehicle; the collision sensor 700 is connected to the front collision beam 600 and is used to detect collision signals of the vehicle.

[0077] Based on this, when a vehicle collides, the obstacle typically impacts the front collision beam 600, which can initially absorb the collision energy. The collision sensor 700 is directly connected to the front collision beam 600 and can detect the physical changes during a collision, transmitting signals in a timely manner. The collision sensor 700 ensures timely monitoring before a collision, facilitating rapid inflation of the airbag 300 to ensure the safety of the occupants.

[0078] For example, the collision sensor 700 may include sensitive elements such as piezoelectric crystals and strain gauges. The sensitive elements sense the impact force, acceleration, or vibration signal generated by the collision, and upload this data to the central processing unit, which then determines whether an impact has occurred.

[0079] As another example, the collision sensor 700 can be connected to the front collision beam 600 by welding or by snap-fit. The number of collision sensors 700 can be one or more.

[0080] In another embodiment, please refer to Figure 2 The front cabin structure 13 also includes a heat dissipation component 800, which is connected to the cabin body 100 and located between the front collision beam 600 and the airbag 300.

[0081] Based on this, the heat dissipation component 800, through the gap between the front collision beam 600 and the airbag 300, allows air to convect at the heat dissipation component 800 when the vehicle is in motion. The heat dissipation component quickly removes heat through the airflow, effectively maintaining the working temperature of the components requiring heat dissipation within the engine compartment 100 within a reasonable range and ensuring stable performance.

[0082] For example, the heat dissipation component 800 can be connected to the nacelle body 100 by bolts or clips.

[0083] In some examples, the heat dissipation component 800 can be an air-cooled heat dissipation component, which dissipates heat by utilizing the heat exchange between the heat dissipation component and the gas through the synergistic effect of heat conduction and air convection, thereby maintaining the component temperature within a reasonable range.

[0084] In some embodiments, see Figure 2 and combined Figure 3 and Figure 4The forward cabin structure 13 also includes straps and buckles. The female buckle of the buckle is connected to one end of the strap, and the male buckle of the buckle is connected to the other end of the strap. The airbag 300 has an uninflated state and an inflated state. When the airbag 300 is in the uninflated state, the straps bind the airbag 300, and the male buckle is inserted into the female buckle. When the airbag 300 is in the inflated state, the male buckle is disengaged from the female buckle.

[0085] Based on this, when the airbag 300 is in an inflated state, the straps secure it by interlocking the male and female buckles. This firmly restrains the folded airbag 300 within its preset position in the forward cabin structure 13, ensuring its stability when not in operation. When the airbag 300 needs to inflate and deploy, the male and female buckles disengage, allowing for a quick and smooth inflation process and deployment to the predetermined shape, providing timely protection.

[0086] It should be noted that the load-bearing capacity of the male and female buckles of the buckle is much less than the expansion force when the airbag 300 is inflated and deployed. This is so that the male and female buckles will disengage during the inflation of the airbag 300, allowing the straps to automatically untie and ensuring that the airbag 300 can be easily deployed when inflated.

[0087] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
