Description

Technical Field

[0001] This invention relates to the field of vehicle safety technology, and in particular to a triangular window rear pillar structure and a vehicle. Background Technology

[0002] Currently, some MPV models on the market, due to their weight, are prone to inward bending and deformation of the A-pillar, a key load-bearing component of the front structure, in frontal or offset collisions. This can lead to direct impact between the driver's head and chest and the A-pillar, seriously threatening occupant safety. To meet collision safety requirements, an additional pillar is usually added behind the front quarter window as a load-bearing structure. In this case, the quarter window area is supported by two pillars, resulting in a larger blind spot, especially when turning, which can obstruct the driver's view to some extent.

[0003] To address the above issues, existing technologies generally employ a solution that reduces the cross-sectional area of ​​the A-pillar while simultaneously increasing the strength of the A-pillar material. However, this solution still cannot effectively solve the problem of a large blind spot. There are also solutions that use cameras to increase the field of vision, but these solutions would increase the research and development costs and complexity of automobiles. Summary of the Invention

[0004] The main objective of this invention is to propose a triangular window rear pillar structure and vehicle, aiming to provide a triangular window rear pillar structure that is simple in structure, low in cost, and can effectively reduce blind spots.

[0005] To achieve the above objectives, the present invention proposes a rear column structure for a triangular window, comprising: The column body is movably disposed in the window frame of the triangular window along the first direction, so that it has a concealed position for being hidden inside the window frame of the triangular window and a supporting position for being extended out of the window frame of the triangular window during its movement. The mating part is provided in the window frame of the triangular window and is disposed opposite to the column body in the first direction, so as to mate with the column body when the column body moves to the support position; The first drive unit is driven to be connected to the column body; Collision sensors are used to provide pre-collision signals for the vehicle; and, A control device, electrically connected to the collision sensor and the first drive unit, is used to control the first drive unit to operate when a pre-collision signal is received, so that the column body moves to the support position.

[0006] In one embodiment, the first driving part includes a pop-out member and a locking member. The pop-out member always acts on the column body with a pop-out force that moves toward the support position. The locking member is electrically connected to the control device and has a locked state and an unlocked state, so as to lock the column body in the concealed position in the locked state.

[0007] In one embodiment, the ejector is configured as a spring, and the end of the spring is connected to the end of the column body; The locking element is a first electromagnet, which is installed inside the window frame of the triangular window and is electrically connected to the control device. An adsorption plate is fixedly provided on the column body so that when the column body is in a concealed position, the magnetic adsorption plate corresponds to the first electromagnet. By energizing the first electromagnet, the first electromagnet attracts the magnetic adsorption plate, thereby locking the column body in the concealed position.

[0008] In one embodiment, the rear pillar structure of the triangular window further includes a second electromagnet. The second electromagnet is disposed within the window frame of the triangular window and spaced apart from the first electromagnet in a first direction, so that when the pillar body is in the supported position, the magnetic attracting piece corresponds to the second electromagnet. The second electromagnet is electrically connected to the control device. By energizing the second electromagnet, the second electromagnet attracts the magnetic attracting piece, thereby locking the pillar body in the supported position.

[0009] In one embodiment, the mating part is movably disposed on the window frame of the triangular window along a first direction, so that it has a first position for being hidden inside the window frame of the triangular window and a second position for cooperating with the column body during its movement. The rear pillar structure of the triangular window also includes a second driving part, which is drivenly connected to the mating part and electrically connected to the control device.

[0010] In one embodiment, the second driving unit includes: A transmission rack extends along a first direction and is fixedly connected to the mating part, so as to drive the mating part to move along the first direction; A transmission gear meshes with the transmission rack to drive the transmission rack to move in a first direction when rotated; and, The motor is electrically connected to the control device and driven by the transmission gear.

[0011] In one embodiment, the rear column structure of the triangular window further includes two buffer portions, which are respectively disposed at two ends opposite to the mating portion and the column body.

[0012] In one embodiment, the travel distance of the column body from the concealed position to the supported position is between 200mm and 400mm, and the travel time is less than 50ms.

[0013] In one embodiment, the collision sensor is configured as one of an accelerometer, a millimeter-wave radar, and a camera.

[0014] The present invention also proposes a vehicle including the above-described triangular window rear pillar structure, the triangular window rear pillar structure comprising: The column body is movably disposed in the window frame of the triangular window along the first direction, so that it has a concealed position for being hidden inside the window frame of the triangular window and a supporting position for being extended out of the window frame of the triangular window during its movement. The mating part is provided in the window frame of the triangular window and is disposed opposite to the column body in the first direction, so as to mate with the column body when the column body moves to the support position; The first drive unit is driven to be connected to the column body; Collision sensors are used to provide pre-collision signals for the vehicle; and, A control device, electrically connected to the collision sensor and the drive unit, is used to control the first drive unit to operate when a pre-collision signal is received, so that the column body moves to the support position.

[0015] The technical solution provided by this invention improves the overall structure's impact resistance by movably mounting the pillar body within the window frame of the triangular window, allowing it to be concealed within the window frame or extend beyond it to connect the upper and lower frames, depending on the actual situation. Specifically, by providing a mating part relative to the pillar body in a first direction, the pillar body is limited by the mating part when it moves to the support position, forming a support structure. By incorporating the collision sensor, control device, and first drive unit, the pillar body can quickly move to the support position and engage with the mating part when the vehicle issues a pre-collision signal, ensuring the vehicle meets collision requirements before impact. When the vehicle does not receive a pre-collision signal, the pillar body is concealed within the triangular window frame, significantly reducing the driver's blind spot and resolving the conflict between the safety support and obstructed view of the rear pillar.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0023] Currently, some MPV models on the market, due to their weight, are prone to inward bending and deformation of the A-pillar, a key load-bearing component of the front structure, in frontal or offset collisions. This can lead to direct impact between the driver's head and chest and the A-pillar, seriously threatening occupant safety. To meet collision safety requirements, an additional pillar is usually added behind the front quarter window as a load-bearing structure. In this case, the quarter window area is supported by two pillars, resulting in a larger blind spot, especially when turning, which can obstruct the driver's view to some extent.

[0024] To address the above issues, existing technologies generally employ a solution that reduces the cross-sectional area of ​​the A-pillar while simultaneously increasing the strength of the A-pillar material. However, this solution still cannot effectively solve the problem of a large blind spot. There are also solutions that use cameras to increase the field of vision, but these solutions would increase the research and development costs and complexity of automobiles.

[0025] Therefore, the main objective of this invention is to propose a triangular window rear pillar structure and vehicle, which aims to provide a triangular window rear pillar structure that is simple in structure, low in cost, and can effectively reduce blind spots.

[0026] Please refer to Figure 1 This invention proposes a rear pillar structure 100 for a triangular window, comprising a pillar body 1, a mating part 2, a first driving part 3, a collision sensor, and a control device. The pillar body 1 is movably disposed on the window frame 201 of the triangular window 200 along a first direction, having a concealed position for hiding within the window frame 201 of the triangular window 200 and a supporting position for extending out of the window frame 201 of the triangular window 200 during its movement stroke. The mating part 2 is disposed on the window frame 201 of the triangular window 200 and is disposed opposite to the pillar body 1 in the first direction, so as to cooperate with the pillar body 1 when the pillar body 1 moves to the supporting position. The first driving part 3 is drivenly connected to the pillar body 1. The collision sensor is used to feed back a pre-collision signal of the vehicle. The control device is electrically connected to the collision sensor and the driving part, and is used to control the first driving part 3 to work when a pre-collision signal is received, so that the pillar body 1 moves to the supporting position.

[0027] The technical solution provided by this invention improves the overall structure's impact resistance by movably setting the pillar body 1 within the window frame 201 of the triangular window 200. This allows it to be either hidden within the window frame 201 or extend beyond it to connect the upper and lower window frames 201, depending on the actual situation. Specifically, by providing the mating part 2 relative to the pillar body 1 in a first direction, the pillar body 1 is limited by the mating part 2 when it moves to the support position, forming a support structure. By incorporating the collision sensor, control device, and first drive unit 3, when the vehicle issues a pre-collision signal, the pillar body 1 can quickly move to the support position and engage with the mating part 2, ensuring the vehicle meets collision requirements before a collision. When the vehicle does not receive a pre-collision signal, the pillar body 1 is hidden inside the window frame 201 of the triangular window 200, significantly reducing the driver's blind spot and resolving the conflict between the safety support of the rear pillar and obstructed vision.

[0028] It should be noted that the triangular window 200 is a small, usually triangular, fixed glass located above the front door of the vehicle, between the A-pillar (the pillars on both sides of the windshield) and the front door glass. Its main function is to expand the field of vision and reduce blind spots. The window frame 201 of the triangular window 200 is composed of the longitudinal beam of the roof and the front door panel. It can be understood that in this solution, the window frame 201 of the triangular window 200 has two mounting channels for the pillar body 1 and the mating part 2 to be installed respectively, and has two openings arranged opposite to each other in the first direction, so that the pillar body 1 can extend out and mate with the mating part 2 on the other side.

[0029] It is worth mentioning that the first direction refers to the extension direction of the pillar behind the triangular window in conventional vehicles. The pillar body 1 in this invention moves along the first direction to form a rear pillar extending along the first direction.

[0030] It is understood that the pre-collision signal is a warning signal indicating that the vehicle is about to be collided with. This invention does not limit the specific implementation of the collision sensor; it can be an accelerometer that issues a pre-collision signal when the vehicle's acceleration is abnormal; it can be millimeter-wave radar that issues a pre-collision signal when the radar detects an object rapidly approaching the vehicle; or it can be a camera that detects an approaching object through image recognition to determine whether a pre-collision signal should be issued. Of course, multiple collision sensors can be used in combination to more comprehensively determine whether the vehicle is in a pre-collision state.

[0031] It should also be noted that this solution does not limit the specific implementation of the mating part 2. In one embodiment provided by the present invention, the mating part 2 is configured as a mating block, and the mating block has a mating groove on the side facing the column body 1. The depth direction of the mating groove is a first direction, and it conforms to the shape of the column body 1. This configuration results in a simple structure and a tight fit. In another embodiment of the present invention, the mating part 2 is configured as a protrusion, and the column body 1 has a snap-fit ​​groove on the side facing the protrusion, which conforms to the shape of the protrusion.

[0032] To reduce damage caused by the mating of the column body 1 and the mating part 2, in one embodiment of the present invention, the rear column structure 100 of the triangular window further includes two buffer parts, which are respectively disposed at the two opposite ends of the mating part 2 and the column body 1. Since the column body 1 has a fast response speed, the mating of the column body 1 and the mating part 2 usually causes a significant impact on both. By providing two buffer parts, the damage caused by the impact can be minimized, thereby improving the lifespan of the device.

[0033] It should be emphasized that the travel distance of the column body 1 from the concealed position to the supported position is between 200mm and 400mm, and the travel time is less than 50ms. By limiting the travel distance and travel time of the column body 1, it is ensured that the column body 1 can cooperate with the mating part 2 before a collision occurs, so that the vehicle can meet the collision safety requirements before the collision, thereby improving the safety of this device.

[0034] To achieve rapid response of the column body 1, in one embodiment of the present invention, the first driving part 3 includes a pop-out member and a locking member. The pop-out member always acts with a popping force on the column body 1 moving towards the support position. The locking member is electrically connected to the control device and has a locked state and an unlocked state, so as to lock the column body 1 in the concealed position in the locked state. With this configuration, when the locking member switches to the unlocked state, the column body 1 will quickly receive an acceleration in the first direction to achieve a rapid response effect.

[0035] It should be noted that this solution does not limit the specific implementation of the pop-out component and the locking component. In a preferred embodiment of this solution, the pop-out component is a spring 31, the end of which is connected to the end of the column body 1; the locking component is a first electromagnet 32, which is installed inside the window frame 201 of the triangular window 200 and electrically connected to the control device; a magnetic suction piece 11 is fixedly installed on the column body 1 so that when the column body 1 is in a concealed position, the magnetic suction piece 11 corresponds to the first electromagnet 32. By energizing the first electromagnet 32, the first electromagnet 32 ​​attracts the magnetic suction piece 11, thereby locking the column body 1 in the concealed position. With this configuration, the switching between the locked and unlocked states can be achieved simply by switching the power on and off, improving the response speed. Furthermore, using the spring 31 as the pop-out component structure is simpler and easier to implement.

[0036] In another embodiment of the present invention, the pop-out component is a magnet, and a magnetic block is provided on the side of the column structure away from the mating part 2. The magnetic block and the magnet repel each other. The locking component is a locking block that is movably disposed along the width direction of the column body 1. A locking groove is provided on the column body 1. In the locked state, the locking block moves to engage with the locking groove. In the locked state, the locking block moves away from the column body 1 and does not interfere with the column body 1. With this configuration, the overall structure is relatively simple and easy to control.

[0037] To enhance the strength of the pillar body 1 when in the supported position, in one embodiment of the present invention, the pillar structure 100 behind the triangular window further includes a second electromagnet 4. The second electromagnet 4 is disposed within the window frame 201 of the triangular window 200 and spaced apart from the first electromagnet 32 ​​in a first direction. When the pillar body 1 is in the supported position, the magnetic attracting piece 11 corresponds to the second electromagnet 4. The second electromagnet 4 is electrically connected to the control device. By energizing the second electromagnet 4, the second electromagnet 4 attracts the magnetic attracting piece 11, thereby locking the pillar body 1 in the supported position. With this configuration, when the control device receives a pre-collision signal, it controls the first electromagnet 32 ​​to be de-energized and the second electromagnet 4 to be energized, thereby realizing the detachment of the pillar body 1 from the hidden position to its fixed position. The entire process relies on electrical signal transmission, resulting in a fast response speed while enhancing the strength of the pillar body 1 when in the supported position, ensuring that the vehicle meets collision safety standards.

[0038] In another embodiment, magnetic suction parts that can attract each other are provided on the two ends of the column body 1 and the mating part 2 that cooperate with each other, so that after the column body 1 and the mating part 2 cooperate with each other, they are fixed by the two magnetic suction parts, thereby strengthening the overall strength of the structure. With this arrangement, the structure is simpler.

[0039] To further improve the response speed, in one embodiment of the present invention, the mating part 2 is movably disposed in the window frame 201 of the triangular window 200 along a first direction, so that it has a first position for being hidden within the window frame 201 of the triangular window 200 and a second position for cooperating with the column body 1 during its movement stroke; the rear column structure 100 of the triangular window also includes a second driving part 5, which is drivenly connected to the mating part 2 and electrically connected to the control device. With this configuration, by driving the mating part 2 to move, the movement stroke of the column body 1 can be greatly shortened, thereby indirectly shortening the response time of the column body 1 to the support position and improving the response speed of the device. It should also be noted that this solution does not limit the specific implementation of the second driving unit 5. In one embodiment provided by the present invention, the second driving unit 5 includes a transmission rack, a transmission gear, and a motor. The transmission rack extends along a first direction and is fixedly connected to the mating part 2 to drive the mating part 2 to move along the first direction. The transmission gear meshes with the transmission rack to drive the transmission rack to move along the first direction when rotating. The motor is electrically connected to the control device and is driven by the transmission gear. With this configuration, when the mating part 2 needs to be reset, it is only necessary to control the motor to rotate in the opposite direction, so that the mating part 2 returns to the second position. The structure is simple and easy to assemble. Furthermore, since the motor has a self-locking property, no additional locking component is needed to achieve the positioning of the mating part 2 in the first or second position.

[0040] In another embodiment of the present invention, the second driving part 5 is configured as a second spring and a third electromagnet, with the end of the second spring connected to the end of the mating part 2; the third electromagnet is used to be installed inside the window frame 201 of the triangular window 200 and is electrically connected to the control device; a second magnetic absorbing piece is fixedly provided on the mating part, so that when the mating part 2 is in the first position, the second magnetic absorbing piece corresponds to the third electromagnet, and by energizing the third electromagnet, the third electromagnet attracts the second magnetic absorbing piece, so that the mating part 2 is locked in the first position. With this configuration, the mating part 2 will achieve an outward pop-out acceleration at the instant the third electromagnet is de-energized, improving the response speed, and the second spring is used as the main driving device for the movement of the mating part 2, making the structure simpler and easier to implement.

[0041] The present invention also proposes a vehicle, the vehicle including the above-mentioned triangular window rear pillar structure 100. Since the vehicle includes the triangular window rear pillar structure 100, the specific structure of the triangular window rear pillar structure 100 refers to the above embodiments. Since the triangular window rear pillar structure 100 of this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0042] Furthermore, the vehicle in question is an MPV, which stands for Multi-Purpose Vehicle. It is also commonly referred to as a multi-purpose passenger vehicle or a van, primarily designed for passenger use, emphasizing spatial flexibility and ride comfort. These vehicles typically have a high body and robust A-pillars (using high-strength steel or hot-formed steel to meet collision safety requirements), resulting in a significant blind spot on the driver's side. Therefore, MPVs often feature a triangular window 200 to mitigate this blind spot issue. This invention, by incorporating the triangular window rear pillar structure 100 into an MPV, further improves the blind spot problem. Moreover, the structure is simple, does not significantly increase vehicle manufacturing costs, and is easy to promote.

[0043] The above are merely exemplary embodiments of the present invention and do not limit the scope of the patent of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
