Detailed Implementation

[0039] Battery mounting racks are used to support the batteries of heavy-duty trucks. Heavy-duty trucks refer to commercial vehicles with a gross vehicle weight exceeding 11-12 tons, including tractor-trailers, dump trucks, dump trucks, and cement mixer trucks. During battery swapping, the depleted battery pack is lifted and removed from the heavy-duty truck using fully or semi-automatic battery swapping stations, and replaced with a fully charged battery pack. This allows electric heavy-duty trucks to refuel as quickly as refueling a gasoline vehicle, eliminating range anxiety and charging time concerns. The battery pack needs to be secured within the mounting rack not only to hold it in place but also to facilitate the overall lifting of the battery pack.

[0040] As mentioned in the background section, existing battery mounting brackets lack frame support, resulting in low modal stability, severe swaying, and low pitch stability, leading to frequent cracking failures.

[0041] In view of this, the embodiments of this application provide a battery mounting bracket and electrical equipment, suitable for swapping batteries in heavy-duty trucks. The inclined first and second support structures can effectively resist torques and impacts from different directions, improving the stability of the battery mounting bracket, avoiding swaying of the battery mounting bracket, and reducing the risk of cracking. The mounting frame, the inclined first support structure, and the inclined second support structure together form a stable structure, enhancing the overall rigidity of the battery mounting bracket and effectively solving the problem of easy deformation of the battery frame structure. The mobility of the second support structure facilitates the installation of the battery pack and improves assembly efficiency.

[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0043] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0044] This application provides a battery mounting bracket, including a mounting frame 100, a first support structure 200, and a second support structure 300.

[0045] The mounting frame 100 has an opening on one side along the first direction, so that the battery can be moved into or out of the mounting frame 100 along the first direction through the opening.

[0046] The first support structure 200 is disposed on the mounting frame 100. The first support structure 200 and the opening are disposed opposite to each other along the first direction. The first support structure 200 is disposed at an angle relative to the mounting frame 100.

[0047] The second support structure 300 is movably disposed on the mounting frame 100. The second support structure 300 can close or open the opening. The second support structure 300 is inclined relative to the mounting frame 100.

[0048] It is known that the mounting frame 100 is one of the main load-bearing structures, and the opening provided on one side along the first direction is used to move the mounting package in and out, which facilitates the installation during the battery pack assembly stage.

[0049] It should be noted that the first direction can be understood as... Figure 1 The mounting frame 100 is installed along its length.

[0050] The first support structure 200 is inclined relative to the mounting frame 100. This fixed inclination angle makes it a static diagonal brace, which effectively decomposes the longitudinal force along the first direction into compressive and tensile stresses on the mounting frame 100, preventing the mounting frame 100 from tilting back and forth, thereby resisting deformation with higher efficiency.

[0051] The second support structure 300 provides similar support to the first support structure 200 for the mounting frame, supporting the mounting frame 100 from the other side. By integrating mobility, the second support structure 300 can also serve as an access point for the battery pack installation. When the second support structure 300 is fixed to the mounting frame 100, it ensures the stability of the battery pack within the battery mounting bracket.

[0052] The mounting frame 100, the inclined first support structure 200, and the inclined second support structure 300 together form a stable spatial truss structure, which enhances the overall rigidity of the battery mounting bracket and effectively solves the problem of easy deformation of the battery frame structure. The inclined first support structure 200 and second support structure 300 can efficiently resist torque and impact from different directions, improve the stability of the battery mounting bracket, avoid the swaying phenomenon of the battery mounting bracket, and reduce the risk of cracking of the battery mounting bracket. The mobility of the second support structure 300 facilitates the installation of the battery pack and improves assembly efficiency.

[0053] refer to Figure 2 In some possible implementations, the mounting frame 100 includes a support column 101 arranged in the height direction and a crossbeam 102 arranged in the horizontal direction, with a connection angle 103 formed between the support column 101 and the crossbeam 102.

[0054] The second support structure 300 includes at least one second support rod 310, which is inclined and has a connecting angle 103 at each end.

[0055] Understandably, the mounting frame 100 consists of support columns 101 arranged along the height direction and crossbeams 102 arranged along the horizontal direction. These two types of components are connected at intersections (perpendicularly), naturally forming a connection angle 103 at the connection point. In structural mechanics, the connection angle 103 is the critical node where stress is most concentrated when the frame is subjected to bending moment and torsional loads, and it is also the part most prone to plastic deformation or cracking. Therefore, strengthening the connection angle 103 is the most effective way to improve the stiffness and stability of the entire mounting frame 100.

[0056] The two ends of the second support rod 310 are directly connected to the two connecting corners 103. This connection method makes the second support rod 310 a typical diagonal stiffener (or tie rod / compression rod), which transforms the shear force and bending moment originally borne by the support column 101 and the crossbeam 102 and acting on the connecting corners 103 into the axial tension or compression force inside the second support rod 310, thereby preventing the mounting frame 100 from swaying and suppressing deformation and vibration.

[0057] Therefore, the mounting frame 100 clearly defines the main load-bearing components through the support columns 101 and the crossbeams 102, and directly strengthens the key stress point connection angle 103 through the second support rod 310, changing the frame's stress mode from bending resistance to more efficient tensile and compressive resistance, thereby significantly improving the structural rigidity and modal characteristics of the entire battery mounting frame and effectively suppressing the swaying and deformation generated during heavy truck operation; the second support rod 310, as a diagonal brace, transforms the complex load acting on the connection angle 103 into axial force, enhancing the stability against pitching and torsion, and reducing the risk of frequent cracking failures caused by stress concentration at the connection angle 103 and other locations; without significantly increasing weight and complexity, the battery mounting frame significantly improves the reliability and durability of bearing the huge weight of the heavy truck battery pack by optimizing the force flow transmission path.

[0058] refer to Figure 4 In some possible implementations, the second support structure 300 is provided with a mounting part 320, which is located at the connection corner 103, connected to the support column 101, and connected to the crossbeam 102.

[0059] The second support rod 310 is provided with multiple locking elements 330, and the end of the second support rod 310 can be connected to the mounting part 320 through the multiple locking elements 330.

[0060] Understandably, the second support structure 300 is connected to the connection angle 103 through an independent mounting part 320. The mounting part 320 is configured to connect to both the support column 101 and the crossbeam 102 simultaneously, which is equivalent to acting as an efficient load transition interface. The mounting part 320 effectively disperses and redistributes the concentrated axial force transmitted from the second support rod 310 before it enters the stress concentration point of the mounting frame 100, the connection angle 103, so that it acts on the two core load-bearing components, the support column 101 and the crossbeam 102, thereby optimizing the stress state at the connection angle 103 and preventing fatigue cracking caused by excessive local stress.

[0061] Specifically, the mounting part 320 can be a triangular connecting piece.

[0062] Specifically, the locking element 330 can be a bolt.

[0063] In the continuous high-intensity vibration environment of heavy trucks, bolt preload decay and connection loosening are the main failure modes. Multiple locking parts 330 are used to form a redundant mechanical connection system, which can jointly bear the alternating tensile and compressive loads from the second support rod 310 and effectively resist the shear force that causes relative slippage of the connection surface. This ensures that the connection interface between the second support rod 310 and the mounting frame 100 remains tight and reliable under long-term vibration, maintaining its designed support function.

[0064] During use, the battery pack can be pushed into the second support structure 300 mounting position. After multiple battery packs are assembled, the second support rod 310 is connected to the support column 101 and the crossbeam 102 using the mounting part 320, and the mounting part 320 is fixed using the locking part 330.

[0065] When the battery pack needs to be replaced, the locking part 330 can be removed, the mounting part 320 can be loosened from fixing the second support rod 310, the second support rod 310 can be removed, and the battery pack can be taken out from the opening.

[0066] By simultaneously connecting the support column 101 and the crossbeam 102 through the mounting part 320, the load transmitted by the second support rod 310 is distributed to the main structure of the mounting frame 100, significantly reducing stress concentration at the connection angle 103 and improving the fatigue life of this key node. By using multiple locking parts 330 for connection, a highly reliable vibration-resistant connection interface is established, ensuring that the second support rod 310 can play its diagonal bracing role for a long time and stably, working together with the first support structure 200 to jointly ensure the overall stability and load-bearing capacity of the battery mounting frame.

[0067] In some possible implementations, there are multiple second support rods 310, and multiple second support rods 320 are arranged in a cross pattern.

[0068] Understandably, by intersecting multiple second support rods 310, a stable grid-like or truss-like support system is formed. The intersecting second support rods 310 divide the side of the mounting frame 100 into a series of continuous triangular units. Mechanically, a triangular structure is a geometrically invariant system with extremely high stability. Each second support rod 310 not only resists axial force on its own but also supports each other with the intersecting second support rods 310, jointly converting local surface deformations of the mounting frame 100 (such as bulging or denting) into axial tension and compression of the rods, thereby efficiently resisting lateral loads and solving the problem of battery mounting bracket swaying.

[0069] The multiple intersecting second support rods 310 provide multiple parallel paths for force transmission. When the mounting frame 100 is subjected to local impact or asymmetrical load, the force can be quickly distributed to more surrounding support columns 101 and beams 102 through the intersecting grid, avoiding excessive concentration of force on a single component and improving the reliability of the entire battery mounting frame.

[0070] In some possible implementations, the first support structure 200 includes a plurality of first support rods 210, which are inclined and intersecting.

[0071] Similarly, multiple first support rods 210 are arranged in a cross configuration, dividing the side of the mounting frame 100 into a series of continuous triangular units. Each first support rod 210 not only resists axial force on its own but also supports another first support rod 210 that is crossing it, jointly converting local surface deformations (such as bulging or denting) of the mounting frame 100 into axial tension and compression of the rods, thereby effectively resisting lateral loads and solving the problem of battery mounting bracket swaying. It can also distribute the load of the mounting frame 100 to the surrounding support columns 101 and crossbeams 102, improving the overall reliability of the battery mounting bracket.

[0072] In some possible implementations, the mounting frame 100 includes a first frame 110 and a second frame 120 disposed on both sides of the first frame 110 along a first direction, with an opening formed on the side of the second frame 120 away from the first frame 110.

[0073] The first support structure 200 is disposed on the first frame 110, and the second support structure 300 is connected to the second frame 120.

[0074] refer to Figure 3 The dashed box a contains one of the first frames 110, and the dashed box b contains one of the second frames 120.

[0075] It can be understood that the battery mounting rack is structurally divided into a central main body area (first frame 110) and two side channel areas (second frame 120). The second frame 120 has an opening on the side away from the first frame 110, which is dedicated to the insertion and removal of the battery pack. The first frame 110, as the central main body, has the core function of providing main load-bearing and support.

[0076] The first frame 110 serves as the core load-bearing base, bearing the main weight of the battery pack and the main dynamic loads during driving. Therefore, placing the first support structure 200 on the first frame 110 directly reinforces the core load-bearing area. The cross arrangement of the first support rods 210 enhances the rigidity and stability of the first frame 110 itself, ensuring that the main load-bearing base is robust and reliable, and effectively resisting deformation and vibration caused by the weight of the battery pack.

[0077] Connecting the second support structure 300 to the second frame 120 reinforces the side passage area. The mobility of the second support structure 300 serves the opening and closing function of the opening. The multiple second support rods 310 are arranged in a cross pattern to provide lateral support to the side passage area (second frame 120) when the opening is closed, firmly connecting it to the central main body (first frame 110) to resist swaying and prevent cracking of the side due to structural weakness.

[0078] By dividing the mounting frame 100 into a first frame 110 and a second frame 120, the functional zoning and load path are optimized, the rigidity and deformation resistance of the battery mounting bracket are enhanced, and the stability of the load-bearing capacity is ensured.

[0079] In some possible implementations, a third support structure 400 is also included, which is disposed on the second frame 120.

[0080] The third support structure 400 includes at least one third support rod 410, which is inclined and its two ends are respectively connected to a connecting angle 103 of a second frame 120.

[0081] The third support structure 400 is specifically designed for the second frame 120, enhancing its stiffness and stability and preventing local instability or excessive deformation under load due to structural weakness. The third support rod 410 incorporates multiple small triangular stabilizing units within the second frame 120. By directly connecting the third support rod 410 to the connecting angle 103, the forces acting on the second frame 120 (especially the torsional and bending resistance weakened by the opening) can be efficiently converted into axial forces within the third support rod 410. This significantly enhances the in-plane stiffness and deformation resistance of the second frame 120 locally, enabling it to better coordinate with the first frame 110 and more reliably transmit forces from the second support structure 300.

[0082] In some possible implementations, the first frame 110 is provided with a water tank and a plurality of connecting pipes, which are arranged sequentially at intervals along the height direction, and the water tank can supply coolant to the battery through the connecting pipes.

[0083] The first frame 110 serves as the main load-bearing base for the battery mounting bracket. Its structural strength and spatial position are relatively stable. Placing the water tank on the first frame 110 utilizes the inherent high rigidity and protection of this area, avoiding the structural complexity and additional weight caused by setting up a separate mounting point for the thermal management system. This integrates the load-bearing function and the heat dissipation function in physical space, achieving the integration of the architecture.

[0084] Multiple connecting pipes are arranged at intervals along the height direction, which can be connected to the cooling channels of multi-layer cells or modules inside the battery pack to achieve uniform distribution of coolant in the vertical direction of the battery pack.

[0085] By integrating the water tank and multiple connecting pipes onto the reinforced first frame 110, the stability of the core load-bearing structure is fully utilized, providing a reliable installation foundation for the thermal management system and ensuring the long-term sealing and operational reliability of the coolant transmission interface. The layout of the connecting pipes spaced apart along the height direction facilitates the uniform distribution of coolant and efficient heat exchange within the vertical space of the battery pack, improving the overall performance of the battery pack's thermal management. The integrated design optimizes the spatial layout, avoids additional structures, and achieves lightweighting and functional centralization.

[0086] refer to Figure 5 In a possible implementation, the first frame 110 is provided with a guide structure 130, which extends along a first direction.

[0087] The guide structure 130 is provided with a guide opening 131, and in the first direction, the width of the guide opening 131 gradually decreases along the direction close to the first frame 110.

[0088] The guide structure 130 forms a flared guide shape. By utilizing the converging inclined surface, the large lateral positional tolerance of the battery pack at the entrance is automatically and smoothly corrected to a very small positional tolerance at the exit through sliding contact, ensuring that even if there is a certain positioning deviation in the hoisting equipment, the battery pack can be forcibly guided to the preset position.

[0089] By setting a guide structure 130 with a tapered guide opening 131 on the first frame 110, an efficient and reliable alignment function is provided for the battery pack installation process, which significantly reduces the requirements for the positioning accuracy of the hoisting equipment and improves the success rate and efficiency of battery pack installation.

[0090] Specifically, the guide structure 130 consists of opposing guide plates, which can be made of elastic metal. The elastic deformation effectively buffers and absorbs the impact during battery pack hoisting, reducing the risk of damage to the battery pack casing and the guide structure 130 itself, thus improving the equipment's durability. Simultaneously, the continuous restoring force provided by the elastic metal enhances the correction and alignment effect of the battery pack, ensuring positioning accuracy and guaranteeing that the guide structure 130 maintains reliable performance even after long-term repeated use.

[0091] refer to Figure 6 In some embodiments, a lifting ring mounting block 500 is also provided on the top of the mounting frame 100. The lifting ring mounting block 500 is embedded in the mounting frame 100, and the lifting ring 600 can be threadedly connected to the lifting ring mounting block 500. By providing a detachable lifting ring 600, it is convenient to lift the battery mounting bracket.

[0092] During battery pack installation, as the hoisting equipment moves the battery pack toward the mounting frame 100, the battery pack first enters the wider guide port 131. Even with lateral deviation, the side of the battery pack will contact the tapered slope of the guide port 131. As the battery pack is continuously pushed in along the first direction, the inclined guide surface generates a lateral force, automatically guiding and correcting the position of the battery pack, ensuring it continuously aligns with the battery pack mounting holes. When the battery pack is finally pushed into place, the battery mounting holes on the battery pack automatically align with the shelf mounting holes on the first frame 110, facilitating subsequent locking operations by installers or automated equipment, thus completing a fast and precise installation.
