The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, and therefore only serve as examples, and cannot limit the protection scope of the utility model.

[0054] First of all, it needs to be pointed out that in the following description, some orientation words involved in the technical scheme of the utility model, such as the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like, are all analogically interpreted according to the orientation of the normal parts in the rear assembly of the non-road mine truck, and only serve to facilitate the description of the utility model and simplify the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a specific orientation, structure and operation, and therefore cannot be understood as limiting the utility model.

[0055] In addition, the terms "first" and "second" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features, and therefore the features limited by "first" and "second" can explicitly or implicitly include one or more of the features.

[0056] In this application, unless otherwise explicitly specified and limited, the terms "mounting" and "connection" should be interpreted broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be direct connection, or indirect connection through intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0057] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0058] Example:

[0059] like Figure 1 As shown in the figure, this application discloses a rear assembly for a non-road mining truck. Under the premise of ensuring vehicle driving safety, the rear lighting configuration is improved, thereby optimizing the rear installation space, improving the utilization efficiency of the lights, and reducing the overall vehicle cost. Its specific structure includes: a rear crossbeam 1, an integrated light group 2, and a control circuit 3.

[0060] The rear end face of the tail beam 1 is provided with a functional area 101 and lamp hole areas 102 distributed on both sides of the functional area 101; the functional area 101 is used to install other tail components or to make specific functional layouts (such as installing tow hooks for trailers); each lamp hole area 102 includes two reserved holes 1021 arranged laterally, which are used to install turn signals and brake lights respectively.

[0061] The integrated lamp assembly 2 includes several integrated lamps 21, which are arranged laterally at intervals on the top of the tail beam 1. The number is preferably two, so as to balance the lighting effect and production cost, but it is not limited to this and can also be three, four or other.

[0062] It should be noted that the integrated light 21 combines the functions of a reversing light and a rear light, thus achieving two uses with one light. This reduces the number of taillights, improves the utilization of the rear installation space, and lowers the overall vehicle cost.

[0063] Control circuit 3 is used to control the on / off state of integrated lamp group 2, such as... Figure 6 As shown, the device includes a headlight power supply 31, a rearlight switch 32, a reverse switch 33, a diode 34, and a buzzer 35, specifically configured as follows:

[0064] The negative terminal of the vehicle light power supply 31 is connected to the output terminal of the integrated lamp group 2 to provide electrical energy;

[0065] One end of the rear light switch 32 is connected to the positive terminal of the vehicle light power supply 31, and the other end is connected to the input terminal of the integrated lamp group 2, for turning the rear light function on and off.

[0066] One end of the reversing switch 33 is connected to the positive terminal of the headlight power supply 31 and is used to turn the reversing lights on and off.

[0067] The anode of diode 34 is connected to the other end of reverse switch 33, and the cathode is connected to the input terminal of integrated lamp group 2, in order to prevent the buzzer 35 from being activated when the rear light switch 32 is closed;

[0068] The anode end of the buzzer 35 is connected with the other end of the reverse switch 33, and the cathode end is connected with the negative end of the vehicle lamp power supply 31, for emitting a warning sound when reversing.

[0069] The working principle of the above technical solution is shown as follows:

[0070] When the rear light function needs to be enabled, the rear light switch 32 is closed, so that the vehicle lamp power supply 31, the rear light switch 32 and the integrated lamp group 2 form a closed loop, so that the integrated lamp group 2 is lit, and due to the setting of the diode 34, the current cannot pass through the buzzer 35, thereby avoiding the buzzer 35 from sounding;

[0071] When the reverse light function needs to be enabled, the reverse switch 33 is closed, so that the vehicle lamp power supply 31, the reverse switch 33, the diode 34 and the integrated lamp group 2 form a closed loop, so that the integrated lamp group 2 is lit, and the current also passes through the buzzer 35, so that the buzzer 35 emits a warning sound.

[0072] The application integrates the functions of the reverse light and the rear light on the integrated lamp group 2, and redesigns the control circuit 3, thereby ensuring that the two functions do not interfere with each other, achieving one lamp with two functions, improving the lamp usage rate, reducing the number of tail lamps, thereby reducing the overall vehicle cost, and without the need to set a reserved hole 1021 for installing the reverse light in the lamp hole area 102, thereby optimizing the tail mounting space, forming a functional area 101 in the middle of the rear end face of the tail cross beam 1, which can facilitate the installation or layout of specific functions of other tail components.

[0073] In some embodiments, as shown in Figures 1 to 3 two side plates 4 are vertically arranged and symmetrically mounted on the left and right ends of the tail cross beam 1.

[0074] Specifically, by setting the side plates 4, the area of the left and right ends of the tail cross beam 1 is increased, thereby facilitating the installation and fixation with the mine truck longitudinal beam, thereby improving the connection stability.

[0075] Specifically, by setting the side plates 4, the structural strength of the tail of the mine truck is enhanced, which makes the tail structure more stable and can withstand greater external impact, thereby improving the anti-impact ability of the whole vehicle.

[0076] Specifically, the side plates 4 and the tail cross beam 1 together form a closed tail space, which plays a role in protecting the internal components, can shield and protect the tail internal components such as lamps and electrical circuits, and prevent them from being eroded and damaged by the external environment, thereby facilitating the installation and arrangement of the lamps and other components.

[0077] In summary, by adding the side plates 4, the connection stability and structural strength are improved, and the internal components are protected

[0078] In some embodiments, such as Figures 1 to 3 As shown, it includes: a combined lamp frame 5, which corresponds one-to-one with the lamp hole area 102 and is installed on the rear end face of the tail beam 1, which can ensure that the installed lamps can be fully protected.

[0079] By setting up the combined light frame 5, it is possible to block impacts and corrosion from the rear, so that the light fixtures installed in the light hole area 102 are protected from damage. Its modular design makes it easy to disassemble and assemble when maintenance or repair is required.

[0080] In some embodiments, such as Figure 4 As shown, the cross-section of the tail beam 1 is I-shaped, which not only enhances the strength and rigidity, but also optimizes the tail space layout, providing convenience for the installation of components such as lamps and electrical circuits. It is mainly composed of two parts: inner folding plate 11 and outer folding plate 12.

[0081] The inner fold plate 11 has a concave cross-section, which improves bending resistance, increases structural strength, provides more installation space for internal components, and the opening faces the head of the off-road mining truck, thereby improving structural regularity.

[0082] The outer folding plate 12 has a concave cross-section and is located on the back of the inner folding plate 11, thus cooperating with the inner folding plate 11 to form the I-shaped structure of the tail beam 1, thereby enhancing the overall strength and rigidity of the tail beam 1 and enabling it to withstand greater external forces; in addition, the concave space it forms also provides a stable installation platform for components such as the combined lamp frame 5.

[0083] The above-mentioned structural design of the tail beam 1 significantly enhances the structural strength and rigidity, optimizes the tail space layout, facilitates installation, maintenance and repair, improves structural regularity, and can work together with other components to provide a stable, compact and regular support and installation platform for the tail of the mining truck.

[0084] Based on the above embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the combined light frame 5 includes: a protective plate 51 and a grille cover 52.

[0085] The protective plate 51 has an L-shaped cross-section and is composed of vertical plates 511 and horizontal bars 512;

[0086] The horizontal bar 512 is located on the inner top surface of the outer folding plate 12 and can fit tightly with the outer folding plate 12, thereby enhancing the connection strength between the protective plate 51 and the outer folding plate 12 and improving the installation stability of the combined lamp frame 5. The vertical plate 511 has two lamp position holes 5111 that correspond one-to-one with the reserved hole 1021, ensuring that the vertical plate 511 can be accurately fitted onto the lamp, thereby improving the convenience, accuracy and stability of the installation.

[0087] The grating cover 52 is arranged on the outer side of the vertical plate 511 and covers the lamp position hole 5111. It does not interfere with the lighting of the lamp, and can effectively prevent larger external objects from hitting the lamp, thereby protecting the lamp from damage.

[0088] Through the above design of the combined lamp frame 5, the protection effect is guaranteed, the lamp frame structure is simplified, the manufacturing cost is reduced, and the convenience, accuracy and stability of installation are good.

[0089] In the embodiment, as shown in Figure 1 and Figure 2 It also includes a flexible pad 6 made of soft and elastic material such as rubber, which is arranged one by one between the horizontal bar 512 and the inner top surface of the outer flap 12.

[0090] By adding the flexible pad 6, the impact force from the outside can be effectively absorbed and dispersed, reducing the influence of these external forces on the combined lamp frame 5, thereby reducing the noise generated by the vibration of the combined lamp frame 5, and improving the overall stability of the combined lamp frame 5, preventing it from loosening or shifting during driving.

[0091] In the embodiment, as shown in Figures 1 to 3 The adjacent integrated lamps 21, horizontal bars 512 and outer flaps 12 are connected by the same bolt and nut assembly.

[0092] Through the above setting, the assembly process is simplified, and the structural stability between the components is enhanced, ensuring the overall strength and reliability of the tail assembly, and the components can be easily disassembled and assembled when maintenance or repair is required.

[0093] In the embodiment, as shown in Figure 3 The tail cross beam 1 also includes a support plate 13 which is vertically arranged on the inner side of the inner flap 11 and is arranged in transverse intervals.

[0094] For example, the support plate 13 is provided as two pieces and separates the functional area 101 and the lamp hole area 102.

[0095] By providing the support plate 13, the structural strength of the tail cross beam 1 is enhanced, and the internal space is reasonably divided to facilitate the arrangement and installation of the internal components, optimize the space utilization of the tail cross beam 1, and improve the compactness and installation efficiency of the structure.

[0096] In some embodiments, as shown in Figure 3 A plurality of first mounting holes 41 are provided on the side plate 4, which can realize stable installation of the side plate 4 by cooperating with fasteners such as bolts and nuts, and provide flexible installation options, which can be selected according to actual needs to ensure the stability and reliability of the connection,

[0097] In some embodiments, as shown in Figure 4 The functional area 101 has a plurality of second mounting holes 1011, which cooperate with bolts, nuts, etc. fasteners, to achieve quick disassembly and firm fixation of functional components (such as traction hooks).

[0098] In some embodiments, as shown in Figure 4 The outer flaps 12 have a plurality of third mounting holes 121 arranged transversely and spaced apart on the top surface, which facilitate connection and fixation with other components, especially with the horizontal bars 512 and the integrated lamp 21. The horizontal bars 512 have a plurality of fourth mounting holes 5121 arranged transversely and spaced apart on the top surface, which are used to achieve bolt connection of the horizontal bars 512 with the outer flaps 12.

[0099] By providing the third mounting holes 121 and the fourth mounting holes 5121, flexible installation options are provided, which can be selected according to actual needs, ensuring uniform and reasonable layout, improving the convenience and efficiency of installation, and also providing convenience for future functional expansion.
