Description

Technical Field

[0001] This application relates to the technical field of vehicle escape devices, and more particularly to a vehicle escape device, a seat assembly, and a vehicle. Background Technology

[0002] As a common mode of transportation, automobiles occupy a vital position in the modern transportation system. They not only provide people with convenient travel options but also play an irreplaceable role in various economic and social fields. However, with the continuous increase in car ownership, the incidence of traffic accidents is also rising accordingly, especially in serious collisions, where vehicle safety performance faces severe challenges.

[0003] Existing car door structures have several significant drawbacks. In the event of a collision, especially a side impact, the door lock and hinge areas are easily damaged, rendering the door unable to open and severely hindering passenger escape. Current emergency door opening methods largely rely on external rescue equipment, such as hydraulic shears. However, these devices often suffer from delayed response times in emergencies and may be difficult to use effectively when the vehicle is severely damaged, failing to meet the needs of rapid rescue. Utility Model Content

[0004] This application addresses, to at least some extent, one of the technical problems in the related art.

[0005] Therefore, this application aims to provide a vehicle escape device, seat assembly, and vehicle, which allows for self-rescue by extending a support rod from the base and using a cutting assembly to cut the door when a vehicle accident occurs and the door cannot be opened.

[0006] To achieve the above objectives, in a first aspect, this application provides a vehicle escape device, comprising:

[0007] A base, wherein a receiving cavity is provided on the base;

[0008] A support rod, with a connecting end and a cutting end at its two ends, the connecting end being disposed within the receiving cavity;

[0009] A first movable component is used to adjust the angle of the support rod and the position of the connecting end within the receiving cavity;

[0010] A cutting assembly is disposed at the cutting end of the support rod; the cutting assembly is used to cut the car door.

[0011] In this technical solution, the receiving cavity on the base can accommodate the support rod, ensuring it does not affect occupants in the absence of an accident. The first moving component provides the support rod with flexible adjustment capabilities in space, allowing for precise positioning of both angle and position according to actual cutting needs. The cutting component, acting as the execution part, efficiently completes the cutting task. In the event of a vehicle accident where the doors cannot be opened, the support rod can extend from the base, and the cutting component can be used to cut and achieve self-rescue.

[0012] In some embodiments of this application, the first movable component includes a component disposed at the connection end:

[0013] A connector that is slidably connected to the receiving cavity along the length direction of the receiving cavity;

[0014] A rotary motor, wherein the main body and the rotating shaft of the rotary motor are respectively connected to the connecting end and the connecting member.

[0015] In this technical solution, the sliding capability of the connector along the length of the receiving cavity allows the support rod to be flexibly adjusted in its longitudinal position to adapt to different cutting depths or distances. The rotary motor can adjust the angle of the support rod, thereby adjusting the position of the cutting assembly. This design enables the cutting assembly to be adjusted to the optimal cutting position and angle when facing objects of different shapes and positions.

[0016] In some embodiments of this application, the first moving component includes:

[0017] A first drive motor is disposed within the receiving cavity;

[0018] A drive wheel is disposed within the receiving cavity, and the first drive motor drives the drive wheel to rotate;

[0019] Driven wheel, the driven wheel being disposed within the receiving cavity;

[0020] A timing belt, on which the driving pulley and the driven pulley are fitted;

[0021] The connector is connected to the timing belt.

[0022] In this technical solution, a first drive motor rotates a drive wheel, which in turn moves a synchronous belt, causing the connecting component to move the support rod and the cutting assembly, thus achieving horizontal movement of the cutting assembly. This design allows for automatic adjustment. It not only reduces the complexity and error of manual operation but also improves the efficiency and quality of cutting operations. It solves the problems of traditional vehicle escape devices relying on manual labor and having low adjustment accuracy during position adjustment, providing a more intelligent and precise operating experience for cutting operations.

[0023] In some embodiments of this application, the support rod is a telescopic rod, which includes a sleeve rod and a slide rod slidably connected to the sleeve rod; the ends of the sleeve rod and the slide rod that are far apart from each other are the connecting end and the cutting end, respectively;

[0024] The vehicle escape device also includes a second movable component, which is used to adjust the relative position of the slide bar and the sleeve bar.

[0025] In the technical solution, the telescopic structure of the sleeve and slide bar allows the length of the support rod to be flexibly adjusted according to the actual cutting needs, making it easier to adjust the position of the cutting component and ensuring that the cutting component can be adjusted to the optimal cutting position and angle when facing cutting objects of different shapes and positions.

[0026] In some embodiments of this application, the cutting end is hinged to an adjusting member; the axis of rotation between the cutting end and the adjusting member is a first axis, which is perpendicular to the length direction of the support rod;

[0027] The cutting component is disposed on the adjusting member.

[0028] In this technical solution, the hinged design of the cutting end and the adjusting component provides the cutting assembly with additional flexibility and multi-directional adjustment capabilities. This multi-directional adjustment capability allows the vehicle escape device to easily handle cutting needs at different angles and directions, accurately positioning itself for both straight and curved cuts. Its function is to enhance the adaptability and operational capability of the vehicle escape device in complex cutting environments, enabling the cutting assembly to quickly find the optimal cutting angle and position based on the shape and location of the actual object being cut. This improves the efficiency and success rate of self-rescue.

[0029] In some embodiments of this application, the cutting component includes:

[0030] A cutting seat, which is connected to the adjusting member;

[0031] A second drive motor is disposed on the cutting seat;

[0032] A cutting disc, which is connected to the shaft of the second drive motor.

[0033] In this technical solution, the cutting base serves as a connecting and supporting component, providing a stable mounting foundation for the second drive motor and the cutting disc, ensuring a smooth cutting process. The second drive motor, as the cutting power source, provides strong and stable power output, driving the cutting disc to rotate at high speed for efficient cutting.

[0034] In some embodiments of this application, the adjusting member is hinged to the cutting seat;

[0035] The axis of rotation between the adjusting member and the cutting seat is a second axis; the second axis is perpendicular to both the first axis and the length direction of the support rod.

[0036] In this technical solution, the design further enhances the flexibility and multi-dimensional adjustment capability of the cutting assembly. The second axis is perpendicular to both the first axis and the length direction of the support rod; this multi-axis hinge structure allows the cutting assembly to rotate and position flexibly in three-dimensional space. The cutting assembly can be adjusted not only in the transverse plane but also in the longitudinal plane, thereby finding the optimal cutting position and angle in space.

[0037] In addition, this application also provides a seat assembly, which includes: a seat body and a vehicle escape device as described above;

[0038] The bottom of the seat is provided with a storage space, and the opening of the storage space faces the door closest to the seat.

[0039] The vehicle escape device can be slidably connected to the storage space.

[0040] In this technical solution, the seat assembly, as an important component of the vehicle interior, provides a concealed and easily accessible storage location for vehicle escape devices in its underside storage space. The design, with the opening facing the door closest to the seat, fully considers the need for rapid retrieval in emergencies, enabling the vehicle escape devices to be deployed in the shortest possible time.

[0041] In some embodiments of this application, the storage space is further provided with a pushing device for pushing the vehicle escape device out of the storage space.

[0042] In this technical solution, a pushing device is installed in the storage space of the seat assembly, greatly enhancing the emergency availability and ease of operation of the vehicle escape device. The pushing device can respond quickly in emergencies, smoothly pushing the vehicle escape device out of the storage space, ensuring it can be used immediately. Furthermore, the pushing device can be used to push open the vehicle door, increasing the user's chances of self-rescue.

[0043] In some embodiments of this application, the pushing device includes a push screw and a third drive motor;

[0044] The third drive motor is disposed within the storage space, and the shaft of the third drive motor is connected to the push screw; the push screw is threadedly connected to the base.

[0045] The technical solution employs a pushing device consisting of a push screw and a third drive motor, providing stable and reliable power support for the deployment of the vehicle escape device. The third drive motor, as the power source, provides stable and precise power output, driving the push screw to rotate. The threaded connection between the push screw and the base converts the motor's rotational motion into linear motion, thus enabling the smooth deployment of the vehicle escape device. This structure generates significant thrust, capable of pushing open the car door even when it is deformed, increasing the success rate of self-rescue.

[0046] In addition, this application also provides a vehicle, the vehicle including a body, sensors, doors and a seat assembly as described above, the seat assembly being mounted on the body;

[0047] The door is located near the opening of the storage space on the seat assembly.

[0048] In the technical solution, the seat assembly serves as the carrier of the vehicle escape device. Its stable installation structure ensures the reliability and safety of the escape device during vehicle operation. The layout design of the escape device close to the door allows it to be quickly activated when the door is deformed and cannot be opened normally due to an accident. This allows the device to cut through critical parts such as the door lock and hinges, creating an escape route for passengers.

[0049] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

[0068] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0069] It should be noted that automobiles, as a common mode of transportation, occupy a crucial position in the modern transportation system. They not only provide people with convenient travel options but also play an irreplaceable role in various economic and social fields. However, with the continuous increase in car ownership, the incidence of traffic accidents is also rising accordingly, especially in serious collisions, where vehicle safety performance faces severe challenges.

[0070] Existing car door structures have several significant drawbacks. In the event of a collision, especially a side impact, the door lock and hinge areas are easily damaged, rendering the door unable to open and severely hindering passenger escape. Current emergency door opening methods largely rely on external rescue equipment, such as hydraulic shears. However, these devices often have slow response times in emergencies and may be difficult to use effectively when the vehicle is severely damaged, failing to meet the needs of rapid rescue.

[0071] Based on this, this application proposes a vehicle escape device, a seat assembly, and a vehicle. The device uses a first movable component to adjust the position of a support rod, and a cutting component on the support rod cuts through doors that cannot be opened. This achieves a self-rescue effect and solves the problem of insufficient rapid rescue.

[0072] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0073] Referring to all the accompanying drawings, in one illustrative embodiment of the vehicle escape device of this application, the vehicle escape device includes a base 100. The base 100 serves as the foundation of the vehicle escape device and is used to fix it to the vehicle. It is understood that, in order to facilitate the vehicle escape device in cutting through the vehicle door, the base 100 is preferably positioned close to the vehicle door.

[0074] In some embodiments, the vehicle escape device further includes a support rod 200. The two ends of the support rod 200 are a connecting end and a cutting end, respectively, with the connecting end disposed on the base 100.

[0075] Furthermore, the base 100 has a receiving cavity, and the connecting end is located inside the receiving cavity. The support rod 200 can be stored inside the receiving cavity. In the event of an accident and when the vehicle door cannot be opened, the support rod 200 of the vehicle escape device extends out of the receiving cavity and begins to work.

[0076] In some embodiments, the vehicle escape device further includes a first movable component 300, which is used to adjust the angle of the support rod 200 and the position of the connecting end within the receiving cavity. The position of the support rod 200 can be determined by the first movable component 300, eliminating the need for the occupant to hold it continuously.

[0077] In some embodiments, the vehicle escape device further includes a cutting assembly 500 disposed at the cutting end of the support rod 200; the cutting assembly 500 is used to cut the vehicle door.

[0078] Through the above design, the receiving cavity on the base 100 can accommodate the support rod 200, ensuring it does not affect occupants in the event of an accident. The first moving component 300 provides the support rod 200 with flexible adjustment capabilities in space, allowing for precise positioning of both angle and position according to actual cutting needs. The cutting component 500 serves as the actuating component, efficiently completing the cutting task. In the event of a vehicle accident where the doors cannot be opened, the support rod 200 can be extended from the base 100, and the cutting component 500 can be used for cutting to achieve self-rescue.

[0079] In some embodiments, the first moving component 300 includes a connector 301 disposed at the connecting end, the connector 301 being slidably connected to the receiving cavity along the length direction of the receiving cavity. The sliding capability of the connector 301 along the length direction of the receiving cavity allows the support rod 200 to be flexibly adjusted in the longitudinal position to adapt to different cutting depths or distances.

[0080] In some embodiments, to ensure the angle of the support rod 200 changes so that the cutting assembly 500 extends beyond the receiving cavity, the first moving assembly 300 further includes a rotary motor 302. The main body and shaft of the rotary motor 302 are respectively connected to the connecting end and the connecting member 301. The rotary motor 302 can adjust the angle of the support rod 200, thereby adjusting the position of the cutting assembly 500. This design allows the cutting assembly 500 to be adjusted to the optimal cutting position and angle when facing cutting objects of different shapes and positions.

[0081] Furthermore, the main body of the rotary motor 302 is fixed to the support rod 200. The rotating shaft of the rotary motor 302 is connected to the connector 301. When the rotating shaft of the rotary motor 302 rotates, it will cause the support rod 200 to rotate relative to the base 100.

[0082] In another embodiment, the body of the rotary motor 302 is fixed to the connector 301, and the shaft of the rotary motor 302 is connected to the support rod 200.

[0083] In some embodiments, the sidewall of the receiving cavity is provided with a slide rail, and the connector 301 is provided with a slide groove. The connector 301 achieves a sliding connection through the mating of the slide groove and the slide rail. The slide rail structure can ensure the sliding direction of the connector 301.

[0084] In another embodiment, a slide rail is disposed on the connector 301, and a groove is formed in the side wall of the receiving cavity. When the connector 301 moves, the slide rail slides within the groove.

[0085] In some embodiments, the first moving component 300 further includes: a first drive motor, a driving pulley 303, a driven pulley 304, and a timing belt 305. The first drive motor is disposed within the receiving cavity. The driving pulley 303 is disposed within the receiving cavity, and the first drive motor drives the driving pulley 303 to rotate. The driven pulley 304 is disposed within the receiving cavity. The timing belt 305 is sleeved over the driving pulley 303 and the driven pulley 304. A connecting member 301 is connected to the timing belt 305.

[0086] The first drive motor drives the drive wheel 303 to rotate, which in turn drives the synchronous belt 305 to move, causing the connecting piece 301 to move the support rod 200 and the cutting assembly 500, thus achieving horizontal position movement of the cutting assembly 500. This design can automatically adjust. It not only reduces the complexity and error of manual operation but also improves the efficiency and quality of cutting operations. It solves the problem of traditional vehicle escape devices relying on manual labor and having low adjustment accuracy during position adjustment, providing a more intelligent and precise operating experience for cutting operations.

[0087] In some embodiments, the driving wheel 303 and the driven wheel 304 are gears, and the timing belt 305 is a toothed belt. This combination of gears and toothed belts ensures the accuracy and stability of the transmission, avoids slippage, and allows for precise control of the position adjustment of the cutting assembly 500. Simultaneously, the gear transmission is highly efficient and responds quickly, effectively reducing power loss and ensuring that the vehicle escape device responds quickly and reliably in emergencies, improving the efficiency and quality of the cutting operation and buying valuable time for passengers to save themselves.

[0088] Furthermore, the connector 301 has teeth, which mesh with the timing belt 305. It is worth noting that, to ensure horizontal movement of the connector 301, it must be slidably connected to the receiving cavity via a slide rail and a groove. That is, the connector 301 is limited by the slide rail and groove, and powered by the timing belt 305 driven by the first drive motor.

[0089] Furthermore, the connector 301 is a gear, which is a commonly used standard toothed part. It is low in cost, easy to procure, and saves costs.

[0090] In some embodiments, the connector 301 can be slidably connected to the receiving cavity without the use of slide rails and grooves. The connector 301 is fixed to the timing belt 305, thereby enabling horizontal movement of the connector 301.

[0091] In another embodiment, the first moving component 300 is a pneumatic or hydraulic cylinder. It includes a cylinder body and an output rod, with the cylinder body connected to the base 100 and the output rod connected to the connector 301. Alternatively, the cylinder body is connected to the connector 301, and the output rod is connected to the base 100. Pneumatic or hydraulic cylinders are characterized by high thrust and fast response, ensuring that the cutting component 500 can quickly reach the target position in an emergency, making them particularly suitable for cutting scenarios requiring significant thrust. Their simple and compact structure makes them easy to integrate into the receiving cavity, saving space and offering high reliability, effectively improving the emergency response capability and ease of operation of vehicle escape devices.

[0092] In another embodiment, the first moving component 300 can also be a first screw. The first screw is rotatably connected to the receiving cavity. The connecting member 301 is threadedly connected to the first screw. A first drive motor is used to drive the first screw to rotate. The rotational motion of the first drive motor is converted into the linear motion of the connecting member 301, realizing precise position adjustment of the support rod 200 and the cutting component 500. The screw drive has high precision and stability, ensuring that the cutting component 500 remains stable during movement and meeting the positioning requirements in complex cutting environments.

[0093] In some embodiments, the support rod 200 is a telescopic rod, comprising a sleeve rod 201 and a slide rod 202 slidably connected to the sleeve rod 201; the ends of the sleeve rod 201 and the slide rod 202 that are far apart from each other are the connecting end and the cutting end, respectively. The vehicle escape device also includes a second moving component, which is used to adjust the relative position of the slide rod 202 and the sleeve rod 201. The telescopic structure of the sleeve rod 201 and the slide rod 202 allows the length of the support rod 200 to be flexibly adjusted according to actual cutting needs, making it easier to adjust the position of the cutting component 500 and ensuring that the cutting component 500 can be adjusted to the optimal cutting position and angle when facing cutting objects of different shapes and positions.

[0094] In some embodiments, the second moving component includes a second screw and a second drive motor 502. The second screw is rotatably connected within the sleeve 201, and the slide rod 202 is threadedly connected to the second screw. It is noteworthy that, to ensure the second screw can drive the slide rod 202, neither the sleeve 201 nor the slide rod 202 are shaft-like components, ensuring that the slide rod 202 can only move along the length of the sleeve 201. This design converts the rotational motion of the motor into the linear motion of the slide rod 202, enabling the extension and retraction of the support rod 200 and adjusting the position of the cutting component 500. The threaded connection ensures transmission accuracy and stability, and the structure is compact, highly integrated, and space-saving.

[0095] In another embodiment, the second moving component is a hydraulic cylinder or a pneumatic cylinder. Its cylinder body and piston rod are respectively connected to the sleeve rod 201 and the slide rod 202. Hydraulic or pneumatic drive enables the slide rod 202 to rapidly extend and retract, thereby adjusting the length of the support rod 200 and allowing the cutting component 500 to quickly reach the target position, improving efficiency.

[0096] In some embodiments, the cutting end is hinged to an adjusting member 400; the axis of rotation between the cutting end and the adjusting member 400 is a first axis, which is perpendicular to the length direction of the support rod 200; the cutting assembly 500 is disposed on the adjusting member 400. The hinged design between the cutting end and the adjusting member 400 provides the cutting assembly 500 with additional flexibility and multi-directional adjustment capabilities. This multi-directional adjustment capability allows the vehicle escape device to easily cope with cutting requirements at different angles and directions, accurately positioning itself for both straight and curved cuts. Its function is to enhance the adaptability and operational capability of the vehicle escape device in complex cutting environments, enabling the cutting assembly 500 to quickly find the optimal cutting angle and position based on the shape and location of the actual object being cut, thereby improving the efficiency and success rate of self-rescue.

[0097] In some embodiments, the cutting assembly 500 includes a cutting base 501, a second drive motor 502, and a cutting disc 503. The cutting base 501 is connected to the adjusting member 400. The second drive motor 502 is disposed on the cutting base 501. The cutting disc 503 is connected to the rotating shaft of the second drive motor 502. The cutting base 501, as a connecting and supporting component, provides a stable mounting foundation for the second drive motor 502 and the cutting disc 503, ensuring smooth operation of the cutting process. The second drive motor 502, as a cutting power source, provides strong and stable power output, driving the cutting disc 503 to rotate at high speed, achieving efficient cutting.

[0098] In another embodiment, the cutting assembly 500 is directly a cutting machine, which is fixed to the adjusting member 400. Since the cutting machine is prior art, it will not be described in detail further.

[0099] In some embodiments, the adjusting member 400 is hinged to the cutting base 501; the axis of rotation between the adjusting member 400 and the cutting base 501 is a second axis; the second axis is perpendicular to both the first axis and the length direction of the support rod 200. This design further enhances the flexibility and multi-dimensional adjustment capability of the cutting assembly 500. The second axis being perpendicular to both the first axis and the length direction of the support rod 200, this multi-axis hinge structure allows the cutting assembly 500 to rotate and position flexibly in three-dimensional space. The cutting assembly 500 can be adjusted not only in the transverse plane but also in the longitudinal plane, thereby finding the optimal cutting position and angle in space.

[0100] In some embodiments, the vehicle escape device further includes sensors for detecting the force of a vehicle impact or the magnitude of door deformation. The vehicle escape device is activated to cut when the impact force exceeds a threshold or the door deformation exceeds a threshold.

[0101] In some embodiments, the vehicle escape device further includes a controller for electrical connection with the rotary motor 302, the first drive motor, and the second drive motor 502. When the controller receives a signal from the sensor that exceeds a threshold, the controller controls the operation of the first drive motor, the rotary motor 302, and the second drive motor 502 to achieve automated or semi-automated operation of the vehicle escape device.

[0102] Furthermore, this application also provides a seat assembly, comprising: a seat 600 body and a vehicle escape device as described above; a storage space is provided at the bottom of the seat 600, the opening of which faces the vehicle door nearest to the seat 600; the vehicle escape device is slidably connected to the storage space. As an important component of the vehicle interior, the storage space at the bottom of the seat assembly provides a concealed and easily accessible storage location for the vehicle escape device. The design of the opening facing the vehicle door nearest to the seat 600 fully considers the need for rapid retrieval in emergencies, enabling the vehicle escape device to be used in the shortest possible time.

[0103] In some embodiments, the storage space is further provided with a pushing device 700, which is used to push the vehicle escape device out of the storage space. The placement of the pushing device 700 in the seat assembly's storage space greatly enhances the emergency availability and ease of operation of the vehicle escape device. The pushing device 700 can respond quickly in emergencies, smoothly pushing the vehicle escape device out of the storage space, ensuring that the vehicle escape device can be used immediately. Furthermore, the pushing device 700 can be used to push open the vehicle door, increasing the user's self-rescue success rate.

[0104] In some embodiments, the pushing device 700 includes a pushing screw 701 and a third drive motor 702; the third drive motor 702 is disposed within a storage space, and its shaft is connected to the pushing screw 701; the pushing screw 701 is threadedly connected to the base 100. The pushing device 700, composed of the pushing screw 701 and the third drive motor 702, provides stable and reliable power support for the deployment of the vehicle escape device. The third drive motor 702, as a power source, provides stable and precise power output, driving the pushing screw 701 to rotate. The threaded connection design between the pushing screw 701 and the base 100 converts the motor's rotational motion into linear motion, thereby achieving a smooth deployment of the vehicle escape device. This structure provides significant thrust, enabling the vehicle door to be pushed open even when it is deformed, thus increasing the success rate of self-rescue.

[0105] In another embodiment, the pushing device 700 includes a cylinder or hydraulic cylinder, with its cylinder body and output rod connected to the seat 600 and base 100, respectively. The extension and retraction of the output rod of the cylinder or hydraulic cylinder pushes the vehicle escape device out of the storage space of the seat assembly, allowing it to quickly take place and be easily retrieved by passengers for self-rescue. This design utilizes the high thrust and rapid response characteristics of the cylinder or hydraulic cylinder to ensure that the vehicle escape device can be removed from the storage space and used immediately. Simultaneously, the force of the pushing device 700 helps to open deformed vehicle doors, increasing the success rate of self-rescue. Its structure is simple, highly reliable, and adaptable to the needs of vehicle emergency scenarios.

[0106] In this application, under normal circumstances, the slide bar 202 is housed inside the sleeve bar 201, and the length direction of the sleeve bar 201 is the same as the length direction of the receiving cavity. The sleeve bar 201 and the cutting assembly 500 are completely housed inside the receiving cavity.

[0107] In an emergency, the rotary motor 302 changes the angle of the sleeve 201, causing the cutting assembly 500 to extend outside the receiving cavity. The first drive motor drives the drive wheel 303 to rotate, causing the synchronous belt 305 to move one end of the sleeve 201, bringing the cutting assembly 500 closer to the car door. If the cutting assembly 500 cannot cut the car door, the second moving assembly drives the slide bar 202 to extend from the sleeve 201, allowing the cutting assembly 500 at the end of the slide bar 202 to cut the car door.

[0108] Understandably, the cutting assembly 500 can be selected for its intended use based on the specific situation, primarily for cutting car door sheet metal. The cutting area size is determined according to requirements. Furthermore, in certain special circumstances, such as when a car door is blocked and cannot be opened, the cutting assembly 500 can also be used to cut the car's roof.

[0109] In practical applications, the cutting component 500 is primarily used to cut the sheet metal of car doors. However, it can also be used to cut the lock body of car doors, thereby breaking the lock and allowing the door to be opened.

[0110] Furthermore, this application also provides a vehicle, including a body, sensors, doors, and a seat assembly as described above, the seat assembly being mounted on the body; the doors have openings near storage spaces on the seat assembly. The seat assembly serves as a carrier for the vehicle escape device, and its stable mounting structure ensures the reliability and safety of the escape device during vehicle operation. The layout design of the escape device near the door allows for rapid activation of the escape device in the event of a vehicle accident that causes the door to deform and become unable to open normally, cutting through critical components such as the door lock and hinges to create an escape route for passengers.

[0111] Understandably, this sensor could be the same sensor mentioned in vehicle escape devices.

[0112] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
