Description

Technical Field

[0001] This invention relates to the field of vehicle protection technology, and in particular to an integrated driver protection device for preventing falling objects and rollovers in mining vehicles. Background Technology

[0002] Mining area water sprinkler trucks are specialized vehicles, and compared to other large machinery, their body structure offers limited protection for drivers and passengers. Operating in mining areas exposes them to complex terrain, road conditions, and various large quarrying and transport machinery, increasing the risk of accidents such as vehicle rollovers, overturning, and being struck by falling rocks. Traditional mining area water sprinkler trucks rely solely on the cab for occupant protection, generally lacking additional specialized protective devices against falling rocks or rollovers, posing a safety hazard. Furthermore, with the increasing depletion of traditional petroleum resources, using clean and efficient electricity as a substitute aligns with the low-carbon and green development strategies advocated by countries worldwide. In the field of new energy vehicles, the application of similar protective devices is limited both domestically and internationally.

[0003] Traditional mining vehicles with fuel-powered engines have their protective devices fixed at the bottom of the chassis, with only two pillars supporting the anti-falling object structure above the cab. This results in poor overall stability, lack of anti-rollover function, and weak protective capabilities.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated driver protection device that integrates a falling object protection device and a rollover protection device into one unit, thereby improving the vehicle's protective function.

[0006] To achieve the above objectives / to solve the above technical problems, the present invention is implemented using the following technical solution: An integrated driver protection device includes: a connecting mechanism, an anti-rollover frame, and an anti-falling object mechanism installed sequentially from bottom to top. The connecting mechanism is used to fix the anti-rollover frame to the vehicle frame assembly. The anti-falling object mechanism is connected to the anti-rollover frame through a fixing mechanism and is located on the side of the anti-rollover frame closer to the driver's cab. The anti-rollover frame consists of several horizontal and vertical beams connected together to form a multi-layer rectangular frame.

[0007] The connecting mechanism secures the roll cage to the vehicle frame assembly with bolts, ensuring its stability. The falling object protection mechanism is fixed to the roll cage via a fixing mechanism, protecting the cab. This allows the protective device to function as both a rollover and falling object protection system. Specifically designed to meet rollover protection requirements, the roll cage is wider and taller, achieving the same width as the cab and exceeding its overall height. This ensures the protective device receives the impact first during a rollover, preventing injuries to the driver and passengers caused by cab deformation. Furthermore, the multi-layered rectangular frame, composed of several crossbeams and longitudinal beams, allows space in each layer to house components such as the vehicle's battery and high-voltage distribution box. This integrated roll cage improves overall vehicle space utilization while maintaining protective functionality.

[0008] Furthermore, the connecting mechanism includes a bottom sub-beam and connecting plates. The upper end of the bottom sub-beam is fastened to the roll cage, and the lower end of the bottom sub-beam is fastened to the frame assembly via connecting plates. Three connecting plates are arranged longitudinally along the bottom sub-beam.

[0009] The rollover frame is connected to the vehicle frame assembly via bolts through connecting plates. The bottom sub-beam is welded and fixed to the bottom of the rollover frame as a connecting component. The upper part of the connecting plate is connected to the bottom sub-beam, and the lower part is connected to the vehicle frame assembly. To ensure the stress stability of the protective device, three connecting plates are arranged longitudinally with symmetrical structures on opposite sides. This design fully ensures the overall stability of the protective device during vehicle braking and acceleration.

[0010] Furthermore, the connecting plate has flanges on both sides.

[0011] The connecting plate is formed by bending 8mm thick high-strength steel in one piece, with flanges on both sides, which greatly enhances its resistance to bending deformation and helps resist lateral impact.

[0012] Furthermore, the anti-rollover frame is provided with X-shaped diagonal braces on the left and right sides, and front diagonal braces on the front and rear sides.

[0013] To ensure the stability of the protective device during accidental rollover and turning of the vehicle, the anti-rollover frame is equipped with multiple front diagonal braces on both the front and rear sides, and a set of X-shaped diagonal braces on both the left and right sides. The front diagonal braces, longitudinal beams and transverse beams form a triangular support structure, which improves the overall strength of the anti-rollover frame and enhances its bending and torsional resistance.

[0014] Furthermore, a central column and longitudinal load-bearing diagonal brace are provided on the side of the anti-roll frame near the cab. One end of the central column is fastened to the crossbeam at the bottom of the anti-roll frame, and the other end is fastened to the crossbeam at the top of the anti-roll frame. One end of the longitudinal load-bearing diagonal brace is firmly connected to the middle column, and the other end is firmly connected to the bottom sub-beam. The longitudinal load-bearing diagonal brace and the middle column form a triangular support structure.

[0015] The central column supports the fall arrestor mechanism. To ensure the longitudinal stability of the fall arrestor mechanism under impact from falling objects, as well as during emergency braking and acceleration, the longitudinal load-bearing diagonal brace and the central column form a triangular support structure, improving overall stability. To ensure strength, both the central column and the longitudinal load-bearing diagonal brace are made of large-size, high-thickness rectangular steel with a yield strength of over 700 MPa.

[0016] Furthermore, the fall protection mechanism includes a protective frame and a fall protection structural beam, with the protective frame and the fall protection structural beam being securely connected. The fixing mechanism includes a front upright plate and a rear upright plate. The upper parts of the front upright plate and the rear upright plate are screwed to both sides of the fall arrest structure beam, and the lower parts of the front upright plate and the rear upright plate are connected to the central column by bolts.

[0017] The gaps between the beams of the protective frame are rationally designed to effectively prevent accidental injuries caused by small falling objects sliding onto the cab roof. The connection between the fall arrest mechanism and the anti-rollover frame is a critical load-bearing area requiring high connection strength. A specially designed fixing mechanism secures the fall arrest mechanism. The fall arrest mechanism is clamped and fixed by front and rear uprights. To ensure strength, both front and rear uprights are machined from 8mm thick high-strength steel. The upper parts of the front and rear uprights are bolted to the front and rear sides of the fall arrest structure beam, allowing the front and rear walls of the fall arrest structure beam to be directly fixed to the front and rear uprights respectively. The lower parts of the front and rear uprights are bolted to the front and rear sides of the central column, thus firmly connecting the fall arrest mechanism to the anti-rollover frame.

[0018] Furthermore, the anti-falling object structural beam is provided with an assembly groove, and a plug-welded reinforcing plate is provided in the assembly groove.

[0019] The assembly slot provides a fixing space for installing the front and rear uprights, facilitating the tightening of bolts so that the front and rear walls of the fall arrest structure beam are directly fixed to the front and rear uprights, respectively. Since the fall arrest structure beam is a large-sized square tube profile with a hollow internal structure, multiple welded reinforcing plates are installed inside the fall arrest structure beam to prevent compression deformation of its upper and lower walls when tightening bolts, thereby increasing its structural strength.

[0020] Furthermore, the multi-layer rectangular frame contains multiple horizontal partitions, which divide the interior of the anti-rollover frame into multiple independent placement spaces.

[0021] The independent storage spaces created by the horizontal partitions can be used to store vehicle components such as power batteries, high-voltage distribution boxes, and water tanks, allowing the rollover frame to meet other functional requirements while preventing rollovers.

[0022] Furthermore, the anti-rollover frame also includes a stress transition beam, one end of which is fastened to the rear upright plate, and the other end is fastened to a crossbeam on the side away from the rear upright plate. Several skin fixing beams are provided above the anti-rollover frame.

[0023] Considering the longitudinal force transmission, a force transition beam is designed at the end of the roll cage near the falling object protection mechanism. This beam transfers the force from the front to the rear of the protective device. The structure is bolted to the rear upright plate, thus ensuring the longitudinal stability of the protective device. To facilitate the fixing of the top skin, several skin fixing beams are provided on the top of the roll cage.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. The anti-falling object mechanism and the anti-rollover frame are combined together by a fixing mechanism, so that the protective device has the functions of anti-rollover and anti-falling object. The anti-rollover frame is a multi-layer rectangular frame composed of several cross beams and longitudinal beams. The space of each layer can be used to place the vehicle's battery and high-voltage distribution box and other components. While ensuring the protective function, the integrated anti-rollover frame can improve the utilization rate of the vehicle space and realize multiple uses of one item.

[0025] 2. The anti-rollover frame is equipped with front diagonal braces on the front and rear sides and X-shaped diagonal braces on the left and right sides, forming a stable triangular support structure with the crossbeams and longitudinal beams, which significantly improves the overall bending and torsional resistance. The central column and the longitudinal load-bearing diagonal braces also form a triangular support, ensuring the longitudinal stability of the anti-falling object mechanism during impact, emergency braking, and acceleration. The anti-falling object structural beam of the anti-falling object mechanism is fixed to the central column by front and rear upright plates, and the anti-falling object structural beam is reinforced with plug welded plates to prevent compression deformation, resulting in high connection strength.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present application or its application or use. Example 1

[0030] like Figure 1 As shown, this embodiment provides an integrated driver protection device. The protection device is installed on the vehicle frame assembly 1 and includes: a connecting mechanism 2, an anti-rollover frame 3, and an anti-falling object mechanism 4 installed sequentially from bottom to top. The connecting mechanism 2 is used to fix the anti-rollover frame 3 on the vehicle frame assembly 1. The anti-falling object mechanism 4 is connected to the anti-rollover frame 3 through a fixing mechanism 5. The anti-falling object mechanism 4 is located on the side of the anti-rollover frame 3 near the driver's cab. The anti-rollover frame 3 is a multi-layer rectangular frame formed by connecting several crossbeams 31 and longitudinal beams 32.

[0031] The connecting mechanism 2 is used to fix the rollover frame 3 to the frame assembly 1 with bolts, so that the rollover frame 3 remains stable. The anti-falling object mechanism 4 is fixed to the rollover frame 3 through the fixing mechanism 5 to protect the cab, so that the protective device has both rollover and falling object prevention functions. In order to meet the rollover protection requirements, the rollover frame 3 has been specially widened and heightened so that the protective device is the same width as the cab and the overall height exceeds that of the cab. The purpose is to ensure that the protective device is impacted first during the rollover, thereby avoiding personal injury accidents to the driver and passengers caused by the deformation of the cab. In addition, the multi-layer rectangular frame composed of several crossbeams 31 and longitudinal beams 32 can be used to place the vehicle's battery and high-voltage distribution box and other components in each layer. While ensuring the protective function, the integrated rollover frame 3 can improve the overall space utilization of the vehicle.

[0032] like Figure 2 , Figure 7 As shown, the connecting mechanism 2 includes a bottom sub-beam 21 and a connecting plate 22. The upper end of the bottom sub-beam 21 is fastened to the anti-rollover frame 3, and the lower end of the bottom sub-beam 21 is fastened to the frame assembly 1 through the connecting plate 22. Three connecting plates 22 are arranged along the longitudinal direction of the bottom sub-beam 21.

[0033] The rollover frame 3 is connected to the frame assembly 1 by bolts through the connecting plate 22. The bottom sub-beam 21 is welded and fixed to the bottom of the rollover frame 3. As a connecting component, the upper part of the connecting plate 22 is connected to the bottom sub-beam 21, and the lower part is connected to the frame assembly 1. In order to ensure the stress stability of the protective device, the connecting plate 22 is arranged in three longitudinal sections with symmetrical structure on opposite sides. This design fully ensures the overall stability of the protective device during vehicle braking and acceleration.

[0034] like Figure 7 As shown, the connecting plate 22 has flanges on both sides.

[0035] The connecting plate 22 is formed by bending 8mm thick high-strength steel in one piece, and has flanges on both sides, which greatly enhances the resistance to bending deformation and helps resist lateral impact.

[0036] like Figures 3-5 As shown, the anti-rollover frame 3 has X-shaped diagonal braces 33 on the left and right sides, and front diagonal braces 34 on the front and rear sides.

[0037] To ensure the stability of the protective device during accidental rollover and turning of the vehicle, the anti-rollover frame 3 is equipped with multiple front diagonal braces 34 on both the front and rear sides, and a set of X-shaped diagonal braces 33 on both the left and right sides. The front diagonal braces 34, longitudinal beams 32 and transverse beams 31 form a triangular support structure, which improves the overall strength of the anti-rollover frame 3 and enhances its bending and torsional resistance.

[0038] like Figure 3As shown, a central column 36 and a longitudinal force-bearing diagonal brace 37 are provided on the side of the anti-rollover frame 3 near the cab. One end of the central column 36 is fastened to the crossbeam 31 at the bottom of the anti-rollover frame 3, and the other end is fastened to the crossbeam 31 at the top of the anti-rollover frame 3. One end of the longitudinal load-bearing diagonal brace 37 is fastened to the middle column 36, and the other end is fastened to the bottom sub-beam 21. The longitudinal load-bearing diagonal brace 37 and the middle column 36 form a triangular support structure.

[0039] The central column 36 is used to support the fall arrest mechanism 4. To ensure the longitudinal stability of the fall arrest mechanism 4 under impact from falling objects, as well as during emergency braking and acceleration, the longitudinal load-bearing diagonal brace 37 and the central column 36 form a triangular support structure, which improves the overall stability. To ensure strength, both the central column 36 and the longitudinal load-bearing diagonal brace 37 are made of large-size, high-thickness rectangular steel with a yield strength of over 700 MPa.

[0040] like Figure 6 As shown, the anti-falling object mechanism 4 includes a protective frame 41 and an anti-falling object structural beam 42, and the protective frame 41 and the anti-falling object structural beam 42 are fastened together. like Figure 7 As shown, the fixing mechanism 5 includes a front upright plate 51 and a rear upright plate 52. The upper parts of the front upright plate 51 and the rear upright plate 52 are screwed to both sides of the anti-falling object structure beam 42, and the lower parts of the front upright plate 51 and the rear upright plate 52 are connected to the central column 36 by bolts.

[0041] The gaps between the beams of the protective frame 41 are rationally designed to effectively prevent accidental injuries caused by small falling objects sliding onto the cab roof. The connection between the anti-falling object mechanism 4 and the anti-rollover frame 3 is a critical load-bearing area requiring high connection strength. A specially designed fixing mechanism 5 secures the anti-falling object mechanism 4. The anti-falling object mechanism 4 is clamped and fixed by the front upright plate 51 and the rear upright plate 52. To ensure its strength, both the front and rear upright plates are machined from 8mm thick high-strength steel. The upper parts of the front upright plate 51 and the rear upright plate 52 are bolted to the front and rear sides of the anti-falling object structural beam 42, allowing the front and rear walls of the anti-falling object structural beam 42 to be directly fixed to the front and rear upright plates respectively. The lower parts of the front upright plate 51 and the rear upright plate 52 are bolted to the front and rear sides of the central column 36, thus firmly connecting the anti-falling object mechanism 4 to the anti-rollover frame 3.

[0042] like Figure 6 As shown, an assembly groove 421 is provided on the anti-falling object structural beam 42, and a plug-welded reinforcing plate 422 is provided in the assembly groove 421.

[0043] The assembly slot 421 provides a fixing space for installing the front upright plate 51 and the rear upright plate 52, which facilitates the tightening of bolts, so that the front and rear walls of the anti-falling object structural beam 42 are directly fixed to the front upright plate 51 and the rear upright plate 52, respectively. Since the anti-falling object structural beam 42 is a large-size square tube profile with a hollow internal structure, in order to prevent the upper and lower walls from being compressed and deformed when tightening the bolts, multiple plug-welded reinforcing plates 422 are installed inside the anti-falling object structural beam 42 to increase its structural strength.

[0044] like Figure 5 As shown, the multi-layer rectangular frame has multiple horizontal partitions, which divide the interior of the anti-rollover frame 3 into multiple independent placement spaces.

[0045] The independent storage space created by the horizontal partition can be used to store vehicle components such as power batteries, high-voltage distribution boxes, and water tanks, allowing the rollover frame 3 to meet other functional requirements while preventing rollover.

[0046] like Figure 7 As shown, the anti-rollover frame 3 also includes a stress transition beam 35. One end of the stress transition beam 35 is fastened to the rear upright plate 52, and the other end is fastened to the crossbeam 31 on the side away from the rear upright plate 52. Several skin fixing beams 38 are provided on the top of the anti-rollover frame 3.

[0047] Considering the longitudinal force transmission, a force transition beam 35 is designed on one end of the anti-rollover frame 3 near the falling object protection mechanism 4. This structure can transfer the force from the front to the rear of the protective device. This structure is fixed to the rear upright plate 52 by bolts, thus ensuring the longitudinal stability of the protective device. To cooperate with the top skin fixing, several skin fixing beams 38 are provided on the top of the anti-rollover frame 3. Example 2

[0048] In order to protect the driver and passengers while taking into account other functional requirements, alarm indicator lights and lights can be installed on the protective frame 41 of the anti-falling object mechanism 4; for easy charging, the charging gun assembly is installed at the bottom of the anti-rollover frame 3.

[0049] For pure electric special-purpose vehicles, this invention fixes the anti-falling object structure 4 to the top of the protective device with screws, resulting in a compact and stable arrangement. While providing anti-falling object and anti-rollover functions, the protective device can also house components such as a power battery pack, high-voltage distribution box, charging gun assembly, and expansion tank, achieving multiple uses in one device.
