Furthermore, this utility model also relates to a new energy heavy-duty truck including the aforementioned chassis-type power battery frame. Background Technology

[0002] New energy heavy-duty trucks, also known as new energy heavy-duty trucks, refer to commercial vehicles powered by new energy sources, possessing significant load-bearing and transportation capabilities. New energy heavy-duty trucks reduce emissions of pollutants such as nitrogen oxides and particulate matter produced by traditional fuel engines. Taking pure electric heavy-duty trucks as an example, they produce no exhaust pollutants during operation, playing a positive role in improving air quality and reducing environmental problems such as smog. This is particularly significant for key pollution emission areas such as logistics transportation and ports around large cities. Due to the development trend of new energy heavy-duty trucks, the demand for power batteries in heavy-duty trucks has been increasing in recent years. Currently, most trucks on the market use rear-mounted battery frames, resulting in a high center of gravity and heavy weight, making the vehicles prone to tilting, and in severe cases, rollovers.

[0003] In conclusion, how to avoid vehicle tilting is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The core of this utility model is to provide a chassis-type power battery frame, which uses high-strength lightweight steel as the material to reduce the overall vehicle weight and the probability of vehicle rollover.

[0035] Another core aspect of this utility model is to provide a new energy heavy truck that includes the aforementioned chassis-type power battery frame.

[0036] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] This application provides a chassis-type power battery frame, including: a vehicle frame 1, a battery frame 2, and a connecting mechanism 3;

[0038] Among them, the frame 1 serves as the base of the power battery frame and is installed on the vehicle body;

[0039] There are two battery frames 2, which are respectively located on both sides of the vehicle frame 1. The battery frames 2 are used to store the power battery and are made of high-strength lightweight steel.

[0040] The connecting mechanism 3 is located between the vehicle frame 1 and the battery frame 2. The connecting mechanism 3 is used to connect the vehicle frame 1 and the battery frame 2.

[0041] Specifically, please refer to the appendix for the structure of frame 1. Figure 1 With appendix Figure 4 On each side of the vehicle frame 1, there is a battery frame 2. The battery frame 2 is a hollow structure used to store new energy batteries. A connecting mechanism 3 is set between the battery frame 2 and the vehicle frame 1. The strength of the frame is ensured by connecting the crossbeam through the connecting mechanism 3, and the power battery can be pre-installed. In addition, the segmented connection can effectively solve the damage to the battery frame 2 caused by the twisting of the vehicle frame 1. Since the battery frame 2 is made of lightweight high-strength steel, the weight of the entire vehicle is reduced after the chassis power battery frame is installed on the vehicle body, thereby reducing the probability of vehicle rollover and improving safety.

[0042] In addition, the battery frame 2 adopts a split left and right structure, which makes it more convenient to transport.

[0043] Based on the above embodiment, the frame 1 includes a left longitudinal beam 4, a right longitudinal beam 5 and two crossbeams 6. The left longitudinal beam 4 and the right longitudinal beam 5 are connected by the two crossbeams 6 to form a rectangular structure. The left longitudinal beam 4 and the right longitudinal beam 5 have the same length and are shorter than the length of the crossbeams 6.

[0044] Specifically, the structure of the left longitudinal beam 4 and the right longitudinal beam 5 can be referred to in the appendix. Figure 1 The two beams are respectively set at both ends of the crossbeam 6 to connect the two crossbeams 6 and improve the overall integration. As for the structure of the left longitudinal beam 4 and the right longitudinal beam 5, the design concept can refer to the existing technology and is not the main improvement point of this application, so it will not be described in detail here.

[0045] In some embodiments, there are six connecting mechanisms 3, and each battery frame 2 is connected to the vehicle frame 1 through three connecting mechanisms 3.

[0046] Specifically, each battery frame 2 is provided with three connecting mechanisms 3 between it and the crossbeam 6 of the vehicle frame 1. The battery frame 2 is a cuboid structure. In order to ensure structural strength, three connecting mechanisms 3 need to be arranged in parallel along the battery frame 2. The connection between the battery frame 2 and the heavy truck frame 1 is provided with an independent connecting mechanism 3, which can enable the battery frame 2 to be pre-installed with the power battery, and also facilitate disassembly and assembly, thus solving the problem of difficult disassembly and assembly of the power battery.

[0047] In some embodiments, the connecting mechanism 3 includes a first plate 7 and a second plate 8, which are arranged in parallel and fixedly connected by reinforcing ribs. The area of ​​the first plate 7 is smaller than that of the second plate 8. The first plate 7 is connected to the vehicle frame 1, and the second plate 8 is connected to the battery frame 2.

[0048] Specifically, the structure of the connecting mechanism 3 can be found in the attached diagram. Figure 9 The relative dimensions of the first section 7 and the second section 8 can be found in the attached diagram. Figure 5 With appendix Figure 7 The structure of the reinforcing ribs can be referenced in the appendix. Figure 6 With appendix Figure 8 The configuration of connecting mechanism 3 can be found in the appendix. Figure 1 Appendix Figure 2 With appendix Figure 3 During installation, since the length of the battery frame 2 in the vertical direction is greater than the length of the frame 1, the smaller first plate 7 needs to be connected to the crossbeam 6 of the frame 1, and the larger second plate 8 needs to be connected to the battery frame 2. Generally speaking, the upper and lower ends of the second plate 8 are aligned with the upper and lower ends of the battery frame 2, respectively, to avoid structural redundancy.

[0049] Based on the above embodiment, the surfaces of the first plate 7 and the second plate 8 are provided with multiple perforations. The first plate 7 is connected to the vehicle frame 1 by a number of high-strength bolts, and the second plate 8 is connected to the battery frame 2 by a number of high-strength bolts.

[0050] Specifically, both the first plate 7 and the second plate 8 have several through holes distributed on their surfaces. The size of the through holes depends on the size of the high-strength bolts. The high-strength bolts are used to connect the connecting mechanism 3 to the frame 1 and the battery frame 2. The high-strength bolts have a high strength grade and can usually withstand large tensile and shear forces. This allows the frame connection to withstand various complex loads during vehicle operation, including the weight of the vehicle itself, the weight of the cargo, and dynamic loads generated by bumps and vibrations during operation. Under the same connection conditions, the high-strength bolts can provide stronger connection strength, ensure the rigidity of the frame connection parts, reduce deformation at the connection points, and thus improve the stability and reliability of the entire frame.

[0051] In some embodiments, the bottom of the frame 1 is provided with a connecting beam 9, and the two ends of the connecting beam 9 are respectively connected to the bottom of the two battery frames 2.

[0052] Specifically, a connecting beam 9 is provided at the bottom of the frame 1. The connecting beam 9 serves to connect and integrate components. Acting as a link, the connecting beam 9 tightly connects the longitudinal beams of the frame 1 and other related components, effectively improving the stability of the two battery frames 2 on both sides of the frame 1, as shown in the attached diagram. Figure 1 As shown, the bottom of the two battery frames 2 on the left and right sides of the frame 1 is provided with three assembled connecting crossbeams 9 for support, ensuring that the frame can be regarded as a whole structure after being installed in the vehicle, thereby improving the overall performance of the frame.

[0053] In some embodiments, the battery frame 2 includes a base plate, a side plate, and a top limiting rod, with the base plate and the side plate fixedly connected and the top limiting rod and the side plate detachably connected.

[0054] Specifically, the structure of battery frame 2 can be found in the attached diagram. Figure 1 The main components of the battery frame 2 are the base plate and the side plate. The base plate supports the new energy battery, and the height of the side plate depends on the height of the new energy battery. The side plate works in conjunction with the top limiting rod to limit the new energy battery and prevent it from shaking during vehicle operation. The top limiting rod and the side plate are detachably connected, preferably by high-strength bolts, to facilitate the installation of the new energy battery. It should be noted that welding is generally not used to connect the top limiting rod and the side plate because when the connection between the top limiting rod and the side plate is required, the new energy battery is already placed inside the battery frame 2, and welding may affect the new energy battery.

[0055] In some embodiments, the left longitudinal beam 4 and the right longitudinal beam 5 are provided with multiple through holes, and the left longitudinal beam 4 and the right longitudinal beam 5 are connected to the vehicle body by high-strength bolts.

[0056] Specifically, the top of the left longitudinal beam 4 and the right longitudinal beam 5 are provided with multiple through holes, which are connected to other structures of the vehicle body by high-strength bolts, making it easy to pre-install new energy batteries.

[0057] Based on the above embodiment, a step frame 10 is provided on the battery frame 2.

[0058] Specifically, step frames 10 are provided on the side panels of the battery frame 2, and multiple step frames 10 are provided to facilitate the installation of new energy batteries by construction personnel and improve the integration of the frame. The step frames 10 on the battery frame 2 solve the problem that the chassis frame occupies the space on both sides of the frame 1 and there is no place to install the steps. Integrating the step frames 10 into the battery frame 2 can also save costs.

[0059] In addition to the aforementioned chassis-type power battery frame, this utility model also provides a new energy heavy truck that includes the chassis-type power battery frame disclosed in the above embodiments. For the structure of other parts of this new energy heavy truck, please refer to the prior art, which will not be repeated here.

[0060] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0061] The above provides a detailed description of the chassis-type power battery frame and new energy heavy truck provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
