Description

Technical Field

[0001] This invention relates to the field of vehicle protection equipment technology, and in particular to a vehicle windshield protection device and vehicle. Background Technology

[0002] With the continuous development of technology, automobiles have become one of the core means of transportation for people's daily travel. Among them, off-road vehicles are favored by outdoor adventurers and off-road enthusiasts due to their strong adaptability to complex off-road conditions. However, off-road vehicles are mostly used in harsh environments such as wilderness and unpaved roads, and are prone to encountering unexpected situations such as flying gravel and scratches from branches during driving. If the windshield is not equipped with an effective protective device, flying gravel and debris can easily hit or scratch the windshield, which may not only affect the driver's visibility but also directly threaten the personal safety of the driver and front passenger, making it difficult to reliably guarantee the safety of the occupants.

[0003] To address the aforementioned technical problems, windshield protection devices have emerged on the market. For example, a windshield protection device for military vehicles disclosed in Chinese invention patent application (publication number: CN111521067A) includes a bulletproof plate, a hinge mechanism and a linkage device connected to the bulletproof plate, and a locking mechanism connected to the linkage device. The locking mechanism is also connected to an electric push rod. The linkage device includes a horizontal pull rod connected to the hinge mechanism, with one end of the horizontal pull rod hinged to a support rod and the other end of the support rod hinged to the locking mechanism. The locking mechanism includes a sleeve for guiding the movement of the electric push rod, a sliding body located inside the sleeve and hinged to the support rod, a latch connecting the sliding body, and an unlocking block hinged to the sliding body. The unlocking block is also connected to the electric push rod. When the bulletproof plate is in the closed state, the electric push rod drives the unlocking block to open the latch, which is engaged in a slot on the side wall of the sleeve. When the bulletproof plate is in the open state, the latch is engaged in a slot on the side wall of the sleeve, thereby automatically opening and closing the aforementioned protection device.

[0004] However, the aforementioned prior art discloses a windshield protection device for military vehicles, which has the following drawbacks: the device includes multiple core components such as a hinge mechanism, a linkage device, a locking mechanism, and an electric push rod. The components need to be linked together through hinges, snap-fits, etc., involving many parts such as tie rods, support rods, sliding bodies, latches, and unlocking blocks. The large number of parts and the complicated assembly relationships not only increase the process difficulty and cost in the manufacturing stage, but also increase the complexity of later installation and debugging. Furthermore, the complex transmission structure requires extremely high machining precision for the parts. Once a component is worn, deformed, or jammed, it can easily cause the automatic switching function of the entire device to fail.

[0005] Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of complex structure, high failure risk and high maintenance cost of the windshield protection device of off-road vehicles in the prior art, and to propose a vehicle windshield protection device and vehicle.

The input end of the worm gear pair is driveably connected to the output shaft of the motor, and the output end of the worm gear pair is driveably connected to the linkage assembly. The linkage assembly is driveably connected to the protective plate. The drive assembly drives the protective plate to open and close relative to the vehicle's windshield via the linkage assembly.

[0008] Furthermore, when the protective panel is in an open state relative to the windshield, the protective panel can be opened to a set angle; when the protective panel is in a closed state relative to the windshield, the protective panel covers the outside of the windshield.

[0009] Furthermore, the connecting rod assembly includes a connecting rod and a crank, the first end of the crank is drivenly connected to the output end of the worm gear pair, the second end of the crank is rotatably connected to the first end of the connecting rod, and the second end of the connecting rod is rotatably connected to the protective plate.

[0010] Furthermore, by definition, the connection point between the first end of the crank and the output end of the worm gear pair is point A, the hinge point between the second end of the crank and the first end of the connecting rod is point B, and the hinge point between the second end of the connecting rod and the protective plate is point C. When the protective plate is in the open state relative to the windshield, points A, B, and C are on the same straight line.

[0011] Furthermore, point A is located between points B and C.

[0012] Furthermore, the windshield frame is provided with a first mounting bracket, the first end of the crank is provided with a first connecting shaft, the second end of the crank is provided with a second connecting shaft, the first connecting shaft is rotatably connected to the first mounting bracket, the first connecting shaft is drively connected to the output end of the worm gear pair, and the second connecting shaft is rotatably connected to the first end of the connecting rod.

[0013] Furthermore, the crank includes a first connecting rod and a second connecting rod arranged opposite to each other. The two ends of the first connecting rod and the second connecting rod are connected by a first connecting shaft and a second connecting shaft, respectively. The first end of the connecting rod is rotatably connected between the first connecting rod and the second connecting rod.

[0014] Furthermore, the connecting rod is provided with a raised portion, which corresponds to and engages with the first connecting shaft.

[0015] Furthermore, the protective device also includes a control switch located inside the vehicle. The control switch is electrically connected to the motor. The control switch can control the drive assembly to move the linkage assembly, thereby driving the protective plate to stop at an open position, a closed position, or any position between the open and closed positions.

[0022] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] In the description of this invention, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, the term "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0027] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Where applicable, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 12 As shown, a vehicle windshield protection device is disclosed. The vehicle includes a windshield frame 100, and the windshield is disposed within the windshield frame 100. The device comprises a protective plate 1, a drive assembly 2, and a linkage assembly 3. The protective plate 1 is hinged to the windshield frame 100. The drive assembly 2 includes a motor 21 and a worm gear pair 22. The input end of the worm gear pair 22 is driveably connected to the output shaft of the motor 21, and the output end of the worm gear pair 22 is driveably connected to the linkage assembly 3. The linkage assembly 3 is driveably connected to the protective plate 1. The drive assembly 2 drives the protective plate 1 to open and close relative to the windshield via the linkage assembly 3. When the protective plate 1 is in an open state relative to the windshield, it can open to a set angle; when the protective plate 1 is in a closed state relative to the windshield, it covers the outside of the windshield. The connecting rod assembly 3 includes a connecting rod 31 and a crank 32. The first end of the crank 32 is connected to the output end of the worm gear pair 22, the second end of the crank 32 is rotatably connected to the first end of the connecting rod 31, and the second end of the connecting rod 31 is rotatably connected to the protective plate 1.

[0030] Based on the above embodiments, the present invention provides a vehicle windshield protection device. The protection device includes a protective plate 1, a drive assembly 2, and a connecting rod assembly 3. The protective plate 1 is hinged to the windshield frame 100. The drive assembly 2 includes a motor 21 and a worm gear pair 22. The input end of the worm gear pair 22 is driveably connected to the output shaft of the motor 21, and the output end of the worm gear pair 22 is driveably connected to the connecting rod assembly 3. The connecting rod assembly 3 is driveably connected to the protective plate 1. The drive assembly 2 drives the protective plate 1 to open and close relative to the windshield through the connecting rod assembly 3. The present invention achieves an organic unity of protective function and usage flexibility by using the motor 21 and the worm gear pair 22 to drive the connecting rod assembly 3 to open and close the protective plate 1. Furthermore, the present invention has a simple structure, which not only reduces the complexity and implementation difficulty of the manufacturing process, but also simplifies the installation process and subsequent maintenance operations.

[0031] In this embodiment, when the protective plate 1 is in a closed state relative to the windshield, it can completely cover the windshield, forming a fully enclosed protective barrier. This barrier can accurately block the impact and scratches from flying debris, branches, and foreign objects in harsh outdoor environments, while effectively preventing external foreign objects from entering the vehicle's interior. This significantly reduces the risk of injury to passengers and ensures driving safety under harsh conditions. When the protective plate 1 is in an open state relative to the windshield, it can be opened to a set angle without affecting the driver's normal driving vision, ensuring the convenience and safety of driving the vehicle under normal road conditions.

[0032] In this embodiment, the protective plate 1 is provided with an observation hole 13, which includes a first strip-shaped hole extending laterally along the protective plate 1 and a second strip-shaped hole extending vertically along the protective plate 1. The observation hole 13 is used to observe the road conditions and surrounding environment to the maximum extent when the protective plate 1 is closed.

[0033] As another preferred embodiment of the present invention, the connection point between the first end of the crank 32 and the output end of the worm gear pair 22 is defined as point A, the hinge point between the second end of the crank 32 and the first end of the connecting rod 31 is defined as point B, and the hinge point between the second end of the connecting rod 31 and the protective plate 1 is defined as point C. When the protective plate 1 is in the open state relative to the windshield, points A, B, and C are on the same straight line. Point A is located between points B and C. In this embodiment, as... Figure 4As shown, when points A, B, and C are on the same straight line, the crank 32 and connecting rod 31 are in a self-locking state to prevent the protective plate 1 from rotating unexpectedly during vehicle operation. Specifically, the torque formula is M=F*L, where M is the driving torque, F is the driving force acting on the crank 32, and L is the lever arm of the driving force about the hinge point B (i.e., the perpendicular distance from the line of action of the driving force to point B). When points A, B, and C are collinear, the direction of the force exerted by the connecting rod 31 on the crank 32 is along the axis of the connecting rod 31 pointing to point B. At this time, the line of action of the driving force F just passes through point B, resulting in a lever arm L=0. According to the torque formula, the driving torque M=F*0=0. Even if the connecting rod 31 applies a force to the crank 32, it cannot generate an effective torque to make the crank 32 rotate around point A. Therefore, the connecting rod assembly 3 is "locked" in the open position, achieving mechanical self-locking. By designing the protective plate 1 such that points A, B, and C are aligned in a straight line when it is in the open position, a reliable locking mechanism is achieved using zero-torque characteristics. This prevents unintended movement of the protective plate 1 under external force, and combines the advantages of simple structure, self-locking stability, and no need for additional locking devices. This structural design allows the protective plate 1 to be reliably locked in the open position, enabling occupants to step onto the roof by stepping on the protective plate 1. Specifically, occupants can step onto the vehicle's hood, then onto the protective plate 1, and finally onto the roof. When it is necessary to release the locked state of the connecting rod assembly 3, the motor 21 applies a lateral offset force to the crank 32 in a direction other than the axis of the connecting rod 31 through the worm gear pair 22. The hinge point B is displaced to break away from the collinear position. At this time, the direction of the force exerted by the connecting rod 31 on the crank 32 no longer passes through the rotation center point A of the crank 32. At this time, the lever arm L>0, the driving torque M=F*L>0, and the effective transmission is restored. The connecting rod assembly 3 can then be released from the locked state and resume normal movement. This structural design does not require an additional unlocking device, taking into account both ease of operation and structural compactness.

[0034] In another preferred embodiment of the present invention, the windshield frame 100 is provided with a first mounting bracket 101, the first end of the crank 32 is provided with a first connecting shaft 321, and the second end of the crank 32 is provided with a second connecting shaft 322. The first connecting shaft 321 is rotatably connected to the first mounting bracket 101, and the first connecting shaft 321 is drively connected to the output end of the worm gear pair 22. The second connecting shaft 322 is rotatably connected to the first end of the connecting rod 31. The crank 32 includes a first connecting shank 323 and a second connecting shank 324 arranged opposite to each other. The two ends of the first connecting shank 323 and the second connecting shank 324 are respectively connected by the first connecting shaft 321 and the second connecting shaft 322. The first end of the connecting rod 31 is rotatably connected between the first connecting shank 323 and the second connecting shank 324. In this embodiment, as shown... Figure 8 and Figure 10As shown, when the motor 21 is working, it drives the worm gear pair 22 to work. The worm gear pair 22 transmits the rotational force of the motor 21 to the crank 32, causing the second connecting shaft 322 of the crank 32 to rotate synchronously with the worm gear pair 22. The first connecting shaft 321 of the crank 32 drives the connecting rod 31 to move. The connecting rod 31 drives the protective plate 1 to rotate relative to the windshield, thereby realizing the opening and closing of the protective plate 1. In this embodiment, the first end of the connecting rod 31 is rotatably connected between the first connecting handle 323 and the second connecting handle 324. This structural design makes the movement of the connecting rod 31 more stable.

[0035] In this embodiment, as Figure 4 , Figure 9 and Figure 10 As shown, the connecting rod 31 is provided with a raised portion 311, which corresponds to and engages with the first connecting shaft 321. The raised portion 311 prevents interference between the connecting rod 31 and the first connecting shaft 321. Simultaneously, it allows the first connecting shaft 321 to be designed as a single piece, eliminating the need for a segmented structure. This integrated design enhances the strength of the first connecting shaft 321 and improves the reliability of the connecting rod assembly 3.

[0036] In this embodiment, as Figure 9 As shown, the connecting rod 31 has hinge holes 312 at both ends, and the connecting rod 31 is hinged to the second connecting shaft 322 and the second mounting part 12 of the protective plate 1 through the hinge holes 312. The connecting rod 31 has several through holes 313. The through holes 313 enable the connecting rod 31 to achieve a lightweight design.

[0037] As another preferred embodiment of the present invention, the protective device further includes a control switch (not shown in the figure) disposed inside the vehicle. The control switch is electrically connected to the motor 21. The control switch is a rotary switch, which can control the drive assembly 2 to drive the linkage assembly 3 to move, thereby driving the protective plate 1 to an open position, a closed position, or any position between the open and closed positions. In this embodiment, the control logic of the control switch is simpler. When the control switch is rotated to a first maximum position in a first direction, the drive assembly 2 and the linkage assembly 3 cooperate to drive the protective plate 1 to the open position; when the control switch is rotated to a second maximum position in a second direction, the drive assembly 2 and the linkage assembly 3 cooperate to drive the protective plate 1 to the closed position; when the control switch is rotated to any position between the first and second maximum positions, the drive assembly 2 and the linkage assembly 3 cooperate to drive the protective plate 1 to any position between the open and closed positions. The first and second directions are arranged in opposite directions, one being clockwise and the other counterclockwise.

[0038] The present invention also provides a vehicle including the aforementioned vehicle windshield protection device, wherein the vehicle windshield protection device has the same structure as the embodiment of the vehicle windshield protection device described above, and will not be described again.

[0039] In another preferred embodiment of the present invention, the windshield frame 100 includes a first window 103 and a second window 104, and the first window 103 and the second window 104 are respectively provided with the protective device. The windshield frame 100 is provided with a second mounting bracket 102, and the protective plate 1 is provided with a first mounting portion 11, the protective plate 1 being hinged to the second mounting bracket 102 via the first mounting portion 11; the protective plate 1 is provided with a second mounting portion 12, the protective plate 1 being hinged to the second end of the connecting rod 31 via the second mounting portion 12. In this embodiment, as... Figure 12 As shown, the first window 103 and the second window 104 are respectively covered with protective plates 1, and can be independently controlled, increasing the flexibility of use.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
