Description

Technical Field

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

[0002] With the increasing popularity of private cars, car accidents are also increasing year by year, such as vehicles catching fire or falling into water, but rescue is often hindered by a window.

[0003] In existing technologies, the window is usually opened by shattering it to give people trapped inside a chance to survive. However, the fragments generated by shattering the window can injure people. When a vehicle falls into water, the shattering can cause water to enter the vehicle quickly and depressurize it. Moreover, shattered windows can cause passengers to panic and make it easier to lose their chance to escape. Furthermore, when the vehicle is repaired later, the glass needs to be replaced, which is costly. Summary of the Invention

[0004] The main objective of this invention is to provide a window structure, door, and vehicle that is safe and has low maintenance costs when the vehicle is stuck or in an emergency.

[0005] To achieve the above objectives, the present invention proposes a vehicle window structure, the vehicle window structure comprising:

[0006] Mounting rack;

[0007] The glass assembly is movably mounted on the mounting bracket in the vertical direction;

[0008] A drive mechanism for driving the glass assembly to move up and down includes a winch and a pull rope. The winch is rotatably mounted on the mounting frame. One end of the pull rope is wound around the winch, and the other end is fixedly connected to the glass assembly. The winch drives the glass assembly to move up and down during the winding and unwinding of the pull rope. The drive mechanism also includes a drive wheel and a driven wheel. The winch is coaxially connected to the drive wheel. A locking element is provided between the drive wheel and the driven wheel to lock the driven wheel to the drive wheel. Both the drive wheel and the driven wheel are rotatably mounted on the mounting frame. The drive wheel has a locked state fixed relative to the mounting frame and a driven state rotating relative to the mounting frame. The driven wheel has a fixed state fixed relative to the drive wheel and an unlocked state rotating relative to the drive wheel.

[0009] An unlocking mechanism is used to switch the driven wheel from the fixed state to the unlocked state when the driving wheel is in the locked state.

[0010] In one embodiment, the driving wheel and the driven wheel are coaxially connected, and the locking member includes a shear pin, one end of which is fixed to the driving wheel and the other end of which is fixed to the driven wheel;

[0011] The unlocking mechanism is used to drive the driven wheel to rotate relative to the driving wheel when the driving wheel is in the locked state, so that the driven wheel switches from the fixed state to the unlocked state.

[0012] In one embodiment, the unlocking mechanism includes an unlocking part, and a mating part is provided circumferentially on the driven wheel. The unlocking part is movably arranged along the tangential direction of the driven wheel so as to engage with the mating part during its active stroke and drive the driven wheel to rotate.

[0013] In one embodiment, the unlocking part includes a plurality of balls, and the mating part includes a plurality of grooves recessed into the peripheral side of the driven wheel and spaced apart along its circumference.

[0014] The unlocking mechanism includes a sleeve, a stop, and a driving device. The sleeve has an outlet end facing the groove. The sleeve contains a plurality of balls. The stop is located at the outlet end of the sleeve. The driving device drives the plurality of balls to move toward the outlet end of the sleeve and open the stop, so that each ball can engage with a corresponding groove.

[0015] In one embodiment, the window structure further includes a detection device and a control device, the control device being electrically connected to the detection device and the drive device, and used to control the operation of the drive device according to the detection device.

[0016] In one embodiment, the stop portion includes a damping plate; and / or,

[0017] The stop portion includes a movable stop plate, which can open and close the outlet end of the sleeve during its active stroke.

[0018] In one embodiment, the drive wheel includes a gear;

[0019] The drive mechanism further includes a drive motor, which has a drive shaft and a lead screw that meshes with the gear.

[0020] In one embodiment, the window structure further includes a return spring disposed between the mounting bracket and the glass assembly.

[0021] The present invention also proposes a vehicle door, including a window structure, the window structure comprising:

[0022] Mounting rack;

[0023] The glass assembly is movably mounted on the mounting bracket in the vertical direction;

[0024] A drive mechanism for driving the glass assembly to move up and down includes a winch and a pull rope. The winch is rotatably mounted on the mounting frame. One end of the pull rope is wound around the winch, and the other end is fixedly connected to the glass assembly. The winch drives the glass assembly to move up and down during the winding and unwinding of the pull rope. The drive mechanism also includes a drive wheel and a driven wheel. The winch is coaxially connected to the drive wheel. A locking element is provided between the drive wheel and the driven wheel to lock the driven wheel to the drive wheel. Both the drive wheel and the driven wheel are rotatably mounted on the mounting frame. The drive wheel has a locked state fixed relative to the mounting frame and a driven state rotating relative to the mounting frame. The driven wheel has a fixed state fixed relative to the drive wheel and an unlocked state rotating relative to the drive wheel.

[0025] An unlocking mechanism is used to switch the driven wheel from the fixed state to the unlocked state when the driving wheel is in the locked state.

[0026] The present invention also proposes a vehicle that includes the aforementioned door.

[0027] In the technical solution of this invention, the mounting bracket is used to fix the inner panel and outer panel of the car door. The glass assembly is movably mounted on the mounting bracket in the vertical direction. When the glass assembly moves upward, the window is closed; when it moves downward, the window is opened. The drive mechanism drives the pull rope to move up and down during winding and unwinding via a rotatable winch, thereby realizing the vertical movement of the glass assembly. Because a locking element is provided between the driving wheel and the driven wheel, during normal use of the glass assembly's vertical movement, simply driving the driving wheel to rotate in the forward and reverse directions will cause the locking element to drive the driven wheel to rotate, thereby realizing the winding and unwinding of the winch. When the drive wheel is in the locked state, the glass assembly is positioned to close and cover the window. In an emergency, when the glass assembly closes the window, the driven wheel is switched from the fixed state to the unlocked state by the unlocking mechanism, allowing the driven wheel to rotate relative to the mounting bracket. The winch is fixed to the driven wheel and can therefore rotate freely along its axis of rotation, providing freedom for the downward movement of the glass assembly. The glass assembly moves downward due to its own gravity, and the window can be opened at will, providing a safe and low-maintenance window structure in case of vehicle entrapment or emergency.

[0039] With the increasing popularity of private cars, car accidents are also increasing year by year, such as vehicle fires or cars falling into water. However, rescue efforts are often hampered by a broken window. Current technology typically involves breaking the window to create a chance for survival for those trapped inside. However, the shards from the broken window can cause injury; when a vehicle falls into water, the breakage can cause rapid flooding and depressurization, and shattered windows can cause panic among occupants, making escape more difficult. Furthermore, subsequent vehicle repairs require replacing the glass, resulting in high maintenance costs.

[0040] This invention proposes a window structure that provides a safe and cost-effective window structure in case the vehicle is stuck or in an emergency.

[0041] Please see Figure 1 and Figure 2In one embodiment of the present invention, the window structure 100 includes a mounting bracket 1, a glass assembly 2, a drive mechanism, and an unlocking mechanism 8. The glass assembly 2 is movably mounted on the mounting bracket 1 in a vertical direction. The drive mechanism is used to drive the glass assembly 2 to move up and down. The drive mechanism includes a winch 3 and a pull rope 4. The winch 3 is rotatably mounted on the mounting bracket 1. One end of the pull rope 4 is wound around the winch 3, and the other end is fixedly connected to the glass assembly 2. The winch 3 is used to drive the glass assembly 2 to move up and down during the stroke of winding and unwinding the pull rope 4. The drive mechanism also includes a driving wheel 5 and a driven wheel 6. The driving wheel 5 is connected to the driven wheel 8. The winch 3 is connected to the shaft, and a locking member 7 is provided between the driving wheel 5 and the driven wheel 6. The locking member 7 is used to lock the driven wheel 6 to the driving wheel 5. The driving wheel 5 and the driven wheel 6 are rotatably mounted on the mounting frame 1. The driving wheel 5 has a locked state fixed relative to the mounting frame 1 and a driving state that rotates relative to the mounting frame 1. The driven wheel 6 has a fixed state fixed relative to the driving wheel 5 and an unlocked state that rotates relative to the driving wheel 5. The unlocking mechanism 8 is used to switch the driven wheel 6 from the fixed state to the unlocked state when the driving wheel 5 is in the locked state.

[0042] In the technical solution of this invention, the mounting bracket 1 is used to fix the inner panel and outer panel of the car door. The glass assembly 2 is movably mounted on the mounting bracket 1 in the vertical direction. When the glass assembly 2 moves upward, the window is closed; when it moves downward, the window is opened. The drive mechanism drives the pull rope 4 to move up and down during winding and unwinding via a rotatable winch 3, thereby realizing the vertical movement of the glass assembly 2. Because a locking member 7 is provided between the driving wheel 5 and the driven wheel 6, during normal use of the glass assembly 2, only the forward and reverse rotation of the driving wheel 5 is needed to drive the driven wheel 6 to rotate, thereby realizing the winding of the winch 3. When the drive wheel 5 is in the locked state, the glass assembly 2 is positioned to close and cover the window. In an emergency, when the glass assembly 2 closes the window, the driven wheel 6 is switched from the fixed state to the unlocked state by the unlocking mechanism 8, so that the driven wheel 6 can rotate relative to the mounting bracket 1. The winch 3 is fixed to the driven wheel 6 and can therefore rotate freely along its rotation axis, providing freedom for the downward movement of the glass assembly 2. The glass assembly 2 moves downward due to its own gravity, and the window can be opened at will, providing a safe and low-maintenance window structure 100 in case of vehicle entrapment or emergency.

[0043] Specifically, please refer to Figure 3In this embodiment, the driving wheel 5 and the driven wheel 6 are coaxially connected. The locking member 7 includes a shear pin, one end of which is fixed to the driving wheel 5 and the other end of which is fixed to the driven wheel 6. The unlocking mechanism 8 is used to drive the driven wheel 6 to rotate relative to the driving wheel 5 when the driving wheel 5 is in the locked state, so that the driven wheel 6 switches from the fixed state to the unlocked state.

[0044] Thus, the driving wheel 5 and the driven wheel 6 are fixedly connected by the shear pin. When the driving wheel 5 rotates, it can drive the driven wheel 6 to rotate synchronously. Therefore, when the driving wheel 5 rotates, the driven wheel 6 can drive the winch 3 to work, realizing the lifting and lowering of the glass assembly 2. When the driving wheel 5 stops rotating, the driven wheel 6 stops rotating, and the winch 3 does not rotate relative to the mounting frame 1. Ultimately, the glass assembly 2 has no upward driving force, and the glass assembly 2 is restricted by the pull rope 4 and cannot move downward.

[0045] When the unlocking mechanism 8 is in the locked state of the driving wheel 5, it drives the driven wheel 6 to rotate relative to the driving wheel 5. Due to the constraint of the shear pin, the shear pin breaks when the driving force is sufficient. The driven wheel 6 is no longer affected by the constraint of the driving wheel 5, so that the driven wheel 6 switches from the fixed state to the unlocked state. Due to the gravity of the glass component 2, one end of the pull rope 4 will move downward. The winch 3 is also unrestrained and rotates along with it to achieve unwinding. The glass component 2 is no longer restrained by the pull rope 4, making it easier for users or rescuers to move the glass component 2 downward and open the window.

[0046] Specifically, please refer to Figure 3 and Figure 4 In this embodiment, the unlocking mechanism 8 includes an unlocking part, and a mating part is provided on the circumference of the driven wheel 6. The unlocking part is movably configured along the tangential direction of the driven wheel 6 so as to cooperate with the mating part during its active stroke and drive the driven wheel 6 to rotate.

[0047] By moving the unlocking part along the tangential direction of the driven wheel 6, the driven wheel 6 can be pushed to rotate, causing the shear pin to be subjected to shearing force and break.

[0048] Specifically, in this embodiment, the unlocking part includes a plurality of balls 81, and the mating part includes a plurality of grooves 6a recessed in the peripheral side of the driven wheel 6 and spaced apart along its circumference; the unlocking mechanism 8 includes a sleeve 82, a stop part 83, and a driving device 84. The sleeve 82 has an outlet end facing the groove 6a, and the plurality of balls 81 are disposed inside the sleeve 82. The stop part 83 is disposed at the outlet end of the sleeve 82, and the driving device 84 is used to drive the plurality of balls 81 to move toward the outlet end of the sleeve 82 and open the stop part 83, so that each ball 81 can engage with a corresponding groove 6a.

[0049] It is understood that the stop portion 83 includes a damping plate; and / or, the stop portion 83 includes a movable stop plate that can open and close the outlet end of the sleeve 82 during its active stroke.

[0050] Thus, during normal use, the plurality of balls 81 are housed within the sleeve 82, the stop 83 stops at the outlet end of the sleeve 82, the drive device 84 is not in operation, and the driving wheel 5 and the driven wheel 6 are fixed by the shear pin. When it is necessary to unlock the glass assembly 2, the drive device 84 drives the plurality of balls 81 to move toward the outlet end of the sleeve 82, the stop 83 is opened by external force, and the plurality of balls 81 can move from inside the sleeve 82 toward the groove 6a. However, the direction of movement of the balls 81 is along the tangential direction of the driven wheel 6. Thus, when the subsequent balls 81 continue to move toward the outlet end of the sleeve 82, they abut against the balls 81 housed in the groove 6a, pushing the driven wheel 6 so that the driven wheel 6 has a tendency to rotate relative to the driving wheel 5. When the abutting force is large enough, the shear pin is cut by the end faces of the driving wheel 5 and the driven wheel 6 approaching each other, thereby achieving unlocking.

[0051] Please see Figure 4 When the driven wheel 6 rotates counterclockwise, it drives the winch to rotate counterclockwise, thereby raising the glass assembly 2. Furthermore, when the ball bearing 81 continues to move toward the driven wheel 6, it drives the driven wheel 6 to continue to drive the winch 3 to rotate clockwise. At this time, the rope wrapped around the winch 3 drives the glass assembly 2 to descend a portion of the distance to open the window.

[0052] It is understood that the driving device 84 can be driven by a motor push rod, or other driving structures. Preferably, the driving device 84 can be set as a gunpowder charging device, which generates a sufficiently large driving force under the push of gas, so that the shearing pin can be quickly sheared.

[0053] Furthermore, in this embodiment, the window structure 100 also includes a detection device and a control device. The control device is electrically connected to the detection device and the drive device 84, and is used to control the operation of the drive device 84 according to the detection device. It is understood that the detection device is used to detect situations where the vehicle is in a dangerous condition, such as high temperature, high water pressure, or collision. The detection device can be configured as a temperature sensor, a water pressure sensor, or a collision sensor, etc. When the vehicle encounters risks such as collision, fire, or flooding, the control device identifies the detection signal and issues a gas filling command to the propellant filler, causing the gas to push the ball bearing 81 downwards.

[0054] Specifically, please refer to Figure 4 In this embodiment, the driving wheel 5 includes a gear; the driving mechanism further includes a driving motor 9, which has a driving shaft on which a lead screw 10 meshes with the gear. Thus, when the driving motor 9 is working, the lead screw 10 meshes with the gear, forming a lead screw 10 transmission mechanism. When the driving motor 9 stops working, the lead screw 10 not only cannot drive the gear to rotate, but also, through the meshing of its teeth, restricts the relative rotation of the gear, locking the driving wheel 5. This allows the driving wheel 5 to switch between the driving state and the locked state.

[0055] Furthermore, to ensure unrestricted vertical movement of the glass assembly 2 and prevent interference, in this embodiment, the mounting bracket 1 is provided with a vertically extending guide rail. The glass assembly 2 includes glass and a slider 21 fixed to the glass. The slider 21 is provided with a vertically extending groove, and the slider 21 slides in cooperation with the guide rail through the groove. Thus, when the glass assembly 2 moves vertically, the slider 21 cooperates with the guide rail, making the movement of the glass assembly 2 smoother.

[0056] Furthermore, in this embodiment, the window structure 100 also includes a return spring disposed between the mounting bracket 1 and the glass assembly 2. When the glass assembly 2 moves upward, the return spring is stretched. After the winch 3 and the driven wheel 6 are unlocked from the driving wheel 5, the return spring returns to its original deformation, driving the glass assembly 2 downward, ensuring the continuous rotation of the winch 3. This maximizes the window opening area for rescue and escape.

[0057] The present invention also proposes a car door, which includes a car door body and a window structure 100. The specific structure of the window structure 100 is as described in the above embodiments. Since the car door 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.

Since the 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.
