[0026] Please refer to Figure 1 and Figure 2 The embodiment provides a new energy heavy truck chassis 100, which comprises a frame 110, a cabin frame 120 arranged at the front end of the frame 110, and suspension support members 130 symmetrically arranged on both sides of the frame 110 along the width direction of the frame 110. The suspension support member 130 is a vertically extending rigid support structure, the lower end of the suspension support member 130 is connected with the side wall of the frame 110, and the upper end of the cabin frame 120 and the suspension support member 130 is connected by plug-in and locking. The brake module, the cooling unit, the control module and the steering module are integrated and installed through the cabin frame 120.

[0027] Specifically, the frame 110 is used as the basic load-bearing structure of the chassis, and is used for supporting the weight of the whole vehicle and the installation of various components; the cabin frame 120 is arranged at the front end of the frame 110, and is used for integrated installation of the brake module, the cooling unit, the control module and the steering module. Through the integrated installation mode, the multiple modules originally installed separately can be pre-assembled on the cabin frame 120, so that the subsequent installation process on the frame 110 is reduced; the suspension support members 130 are symmetrically arranged on both sides of the frame 110 along the width direction of the frame 110, and the suspension support member 130 is a vertically extending rigid support structure, the lower end of which is fixedly connected with the side wall of the frame 110, and the upper end of the cabin frame 120 and the suspension support member 130 is connected by plug-in and locking. In the assembly process, the operator only needs to plug and position the cabin frame 120 pre-integrated with various modules with the suspension support members 130 on both sides, and then lock and fix to complete the installation, without the need for positioning and fixing operation on multiple separate connection points. This connection mode simplifies the assembly process, reduces the number of positioning adjustment and fasteners, significantly shortens the assembly time, greatly improves the installation efficiency of the cabin frame 120, and further meets the high requirements of large-scale production of new energy heavy trucks on production rhythm.

[0028] The new energy heavy truck chassis 100 provided in the application comprises a frame 110, a cabin frame 120 arranged at the front end of the frame 110, and suspension support members 130 symmetrically arranged on both sides of the frame 110 along the width direction of the frame 110. The suspension support members 130 are rigid support structures extending vertically, the lower ends of the suspension support members 130 are connected with the side walls of the frame 110, and the cabin frame 120 and the upper ends of the suspension support members 130 are connected through plug-in and locking. The brake module, the cooling module, the control module and the steering module are integrated and arranged on the cabin frame 120. By arranging the suspension support members 130 symmetrically along the width direction of the frame 110, the connection between the cabin frame 120 and the frame 110 is converted into the plug-in and locking connection between the cabin frame 120 and the upper ends of the suspension support members 130, thereby greatly reducing the number of connection points, and the connection points are concentrated on the suspension support members 130 on both sides of the frame 110, thereby avoiding the problem of scattered connection points. At the same time, the plug-in cooperation can realize the accurate positioning of the cabin frame 120 and the suspension support members 130, thereby ensuring the accuracy of the connection position, and further locking and fixing can further enhance the firmness of the connection, thereby effectively avoiding the loosening or damage of the connection due to vibration or bumping during driving, ensuring the stability and reliability of the chassis structure, and further improving the driving safety of the vehicle.

[0029] In an embodiment of the application, as shown in Figure 1 and Figure 2 , the frame 110 comprises longitudinal beams 111 and cross beams 112 to form a rectangular frame, the cross beams 112 are connected with the longitudinal beams 111 through connecting members, and the suspension support members 130 are connected to the outer sides of the longitudinal beams 111.

[0030] The suspension support members 130 are connected to the outer sides of the longitudinal beams 111, specifically, the lower ends of the suspension support members 130 are arranged in close contact with the outer side walls of the longitudinal beams 111 and are fixed with the longitudinal beams 111 through welding or fastener connection. The outer side of the longitudinal beam 111 is a non-core load-bearing area, and the suspension support member 130 is connected to the outer side of the longitudinal beam 111, which can not only avoid occupying the space on the inner side of the longitudinal beam 111 for installing the cabin frame 120, but also enable the suspension support member 130 to stably support the cabin frame 120 from the outer side of the longitudinal beam 111, thereby ensuring the transverse balance of the cabin frame 120 after installation, and facilitating the installation and maintenance of the suspension support member 130 by the operator from the outer side of the frame 110.

[0031] In an embodiment of the application, as shown in Figure 1 and Figure 2 , a plurality of first mounting holes are arranged on the longitudinal beams 111, the lower ends of the suspension support members 130 are provided with a plurality of second mounting holes 131 corresponding to the first mounting holes, and the suspension support members 130 and the longitudinal beams 111 are connected through fasteners passing through the first mounting holes and the second mounting holes 131.

[0032] In the connecting process, the second mounting hole 131 at the lower end of the suspension support 130 is aligned with the first mounting hole on the longitudinal beam 111, and then a fastener (such as a high-strength bolt, a nut assembly) is passed through the aligned first mounting hole and the second mounting hole 131, and the fixed connection of the suspension support 130 and the longitudinal beam 111 is achieved by tightening the fastener. If the first mounting hole is a threaded hole, the bolt can be directly screwed through the second mounting hole 131 and screwed with the first mounting hole; if it is a light hole, the bolt needs to be screwed through the two holes, and then fixed by a nut. At the same time, a gasket can be arranged between the fastener and the mounting hole to enhance the anti-loosening performance and wear resistance of the connection.

[0033] In an embodiment of the present application, as shown in Figure 1 and Figure 2 The upper end of the suspension support 130 is provided with a positioning column 132, and the cabin frame 120 is provided with a positioning hole matched with the positioning column 132, and the cabin frame 120 is matched with the positioning column 132 through the positioning hole.

[0034] Specifically, the positioning column 132 is fixedly arranged at the upper end of the suspension support 130 in the vertical direction, and the positioning column 132 can be a regular shape such as a cylindrical shape or a square column shape, and is made of high-strength steel material consistent with the suspension support 130, and is fixed with the suspension support 130 by welding or one-piece forming process to ensure that the positioning column 132 has sufficient rigidity and carrying capacity. Correspondingly, the bottom or side of the cabin frame 120 is provided with a positioning hole matched with the number, shape and size of the positioning column 132. When installing the cabin frame 120, first align the positioning hole on the cabin frame 120 with the positioning column 132 at the upper end of the suspension support 130, then put the positioning hole into the positioning column 132, and then lock the cabin frame 120 through the positioning column 132 and the positioning hole. The positioning column 132 is locked to further lock and fix the cabin frame 120 and the suspension support 130, and the whole installation process is completed.

[0035] In an embodiment of the present application, as shown in Figure 1 and Figure 2 The cabin frame 120 has a first mounting layer and a second mounting layer, and the first mounting layer is located above the second mounting layer. The brake module and the cooling unit are installed on the second mounting layer, and the control module, the steering module and the battery module are installed on the first mounting layer.

[0036] The double-layer mounting structure layer-arranges the originally dispersed multiple modules, fully utilizes the longitudinal space of the cabin frame 120, avoids the crowding arrangement of the modules in the same plane, reduces the space interference between the components, makes the internal layout of the cabin frame 120 more compact and orderly, and adapts to the limited installation space at the front end of the new energy heavy truck chassis 100.

[0037] In an embodiment of the present application, as shown in Figure 1 and Figure 2 The cabin frame 120 includes a connecting plate 121, and a first auxiliary frame 122 and a second auxiliary frame 123 connected below the connecting plate 121, the first auxiliary frame 122 and the second auxiliary frame 123 are bolted to the connecting plate 121, the connecting plate 121 is a first mounting layer, and the first auxiliary frame 122 and the second auxiliary frame 123 are a second mounting layer.

[0038] Specifically, the upper ends of the first auxiliary frame 122 and the second auxiliary frame 123 are fixedly connected to the lower surface of the connecting plate 121 by bolts. Specifically, threaded holes are arranged on the lower surface of the connecting plate 121 corresponding to the positions of the first auxiliary frame 122 and the second auxiliary frame 123, and through holes matched with the threaded holes are arranged on the upper ends of the first auxiliary frame 122 and the second auxiliary frame 123. The bolts are inserted through the through holes and matched with the threaded holes to achieve detachable connection of the three. This assembled structure facilitates the production of the cabin frame 120. The connecting plate 121, the first auxiliary frame 122 and the second auxiliary frame 123 can be machined respectively and then assembled. Meanwhile, the connecting plate 121 as the first mounting layer can have the control module, the steering module and the battery module mounted thereon directly. The first auxiliary frame 122 and the second auxiliary frame 123 as the second mounting layer can have the brake module and the cooling unit mounted in the frames thereof respectively, such as fixing the brake module on the first auxiliary frame 122 and fixing the cooling unit on the second auxiliary frame 123.

[0039] In an embodiment of the present application, as shown in Figure 1 and Figure 2 The connecting plate 121 is connected with the suspension support 130 through the reinforcing arms 124.

[0040] Specifically, the reinforcing arms 124 are arranged on the both side edges of the connecting plate 121 and extend outward in the horizontal direction, and the reinforcing arms 124 are integrally formed with the connecting plate 121 (such as being made by cutting and bending a plate material) or are fixed on the both sides of the connecting plate 121 by welding. The length of the reinforcing arms 124 is determined according to the position of the suspension support 130 to ensure that the free ends of the reinforcing arms 124 can extend above the suspension support 130.

[0041] The connecting plate 121 is connected with the suspension support 130 through the reinforcing arms 124. Specifically, positioning holes are arranged on the free ends of the reinforcing arms 124, and the positioning holes are inserted and matched with the positioning columns 132 of the suspension support 130.

[0042] In an embodiment of the present application, as shown in Figure 1 and Figure 2As shown, the connecting plate 121 is provided with a plurality of positioning portions, through which the control module, the steering module and the battery module are respectively installed.

[0043] The positioning portions provide clear installation references for the modules, and the operator can quickly place the modules at the preset positions through the positioning portions, without repeated measurement and adjustment, thereby greatly shortening the installation and positioning time of the modules on the connecting plate 121 and improving the overall assembly efficiency.

[0044] In an embodiment of the present application, as shown in Figure 1 and Figure 2 The material of the cabin frame 120 is magnesium alloy.

[0045] The density of magnesium alloy is much lower than that of traditional steel and aluminum alloy, and the weight of the cabin frame 120 made of magnesium alloy is greatly reduced, thereby reducing the overall curb weight of the new energy heavy-duty truck. Under the same battery capacity, the reduction of the curb weight can reduce the energy consumption during the driving of the vehicle, effectively improve the cruising range of the new energy heavy-duty truck, alleviate the problem of “range anxiety”, and adapt to the demand of long-distance transportation scenarios.

[0046] The present application also discloses a vehicle comprising the new energy heavy-duty truck chassis 100 in the foregoing embodiments. The vehicle comprises the same structure and advantages as the new energy heavy-duty truck chassis 100 in the foregoing embodiments. The structure and advantages of the new energy heavy-duty truck chassis 100 have been described in detail in the foregoing embodiments, and will not be repeated here.

[0047] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
