Description

Technical Field

[0001] This utility model belongs to the field of automotive battery frame technology, and in particular relates to a fast battery swapping frame for new energy micro-trucks. Background Technology

[0002] With the rapid development of new energy vehicle technology, especially the widespread application of urban delivery vehicles such as mini trucks, battery swapping technology has gradually become one of the important development directions of the industry due to its advantages such as high energy replenishment efficiency and no range anxiety.

[0003] In existing battery swapping systems, batteries are typically mounted under the vehicle chassis or frame using a dedicated frame and secured and removed using bolts, locating pins, or other methods. However, during the installation of the battery into the frame, the lack of an effective guiding mechanism can cause the battery to shift when entering the frame, affecting the precise alignment between the battery and the frame and increasing the difficulty and time of installation. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] This utility model provides a fast battery swapping framework for new energy micro-trucks, including:

[0006] The frame is formed by connecting and enclosing horizontal beams and vertical beams in sequence, and the battery body moves upward from the bottom end of the frame to enter the interior of the frame;

[0007] Several ribs are spaced apart on the inner sidewall of the longitudinal beam. One end of each rib near the battery body has an inclined surface. The width of each rib gradually increases along the direction of entry of the battery body.

[0008] Flexible ribs are spaced apart on the inner sidewall of the crossbeam. Each flexible rib includes a plurality of ribs arranged at intervals along the entry direction of the battery body. The ribs protrude from the inner sidewall of the crossbeam, and the thickness of the plurality of ribs gradually increases along the entry direction of the battery body.

[0009] As a preferred embodiment of the above technical solution, the end face of the second rib near the battery body is an arc-shaped end face.

[0010] As a preferred embodiment of the above technical solution, the crossbeam is further provided with a second connecting hole and a positioning sleeve that mate with the battery body. The positioning sleeve allows the positioning post of the battery body to pass through, and the second connecting hole allows the mounting bolt of the battery body to be inserted and locked by a nut.

[0011] As a preferred embodiment of the above technical solution, the crossbeam is provided with a plurality of connecting brackets that cooperate with the vehicle frame, and the connecting brackets are provided with a plurality of connecting holes.

[0012] As a preferred embodiment of the above technical solution, multiple weight-reducing holes are provided at intervals along the length of both the crossbeam and the longitudinal beam.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) This utility model uses multiple ribs arranged at intervals on the inner side wall of the longitudinal beam. By setting an inclined surface at the end of the rib near the battery body, it helps to guide the battery body to enter the frame correctly and automatically correct its position, reduce offset error, reduce installation difficulty and installation time. In addition, the ribs can also effectively increase the overall rigidity of the frame and ensure the stability of the battery during installation and use. Furthermore, since the ribs are arranged at intervals, they form an air flow channel between the battery body and the longitudinal beam, which is conducive to the heat dissipation of the battery.

[0015] (2) This utility model uses multiple flexible ribs arranged at intervals on the inner side wall of the crossbeam. On the one hand, it plays a buffering and protective role, and on the other hand, it plays a guiding role when the battery body enters the frame. The arc-shaped end face serves as a guide slope, making it easier for the battery body to enter the frame during installation. In addition, multiple protruding ribs of different thicknesses form a "step-like" guide. Ribs of different thicknesses continuously correct the posture of the battery body during the insertion process, improving the installation accuracy of the battery body. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 The diagram shown is a three-dimensional representation of the battery swapping frame in the embodiment. Figure 1 ; Figure 2 What is shown is Figure 1 Enlarged schematic diagram of the structure at point A in the diagram; Figure 3 The diagram shown is a front view of the battery swapping frame in the embodiment.

[0027] This device includes:

[0028] The frame is formed by sequentially connecting and enclosing the crossbeams 10 and the longitudinal beams 20.

[0029] The crossbeam 10 is provided with several connecting brackets 11 that cooperate with the vehicle frame;

[0030] The crossbeam 10 is also provided with a second connection hole 21 that mates with the battery body and a positioning sleeve 22;

[0031] The battery body moves upward from the bottom of the frame and enters the frame. The positioning sleeve 22 allows the positioning post of the battery body to pass through, and the connecting hole 21 allows the mounting bolt of the battery body to be inserted and locked by the nut.

[0032] like Figure 3 As shown, 'a' represents the bottom of the frame, and 'b' represents the top of the frame. Figure 3 The direction indicated by the middle arrow is the installation direction of the battery body. The main body of the battery body is rectangular and matches the shape inside the frame. Extended sides are provided on both sides of the corresponding crossbeam 10, and positioning posts and multiple mounting bolts are provided on the extended sides.

[0033] The battery body is connected to the frame by inserting multiple mounting bolts into the connecting holes 21 of the frame and then tightening them with nuts. The positioning sleeve 22 allows the positioning pins on the battery body to pass through, ensuring the correct placement of the battery body.

[0034] The battery housing is mounted on the frame of the new energy micro-truck via the connecting bracket 11. When the battery housing needs to be replaced, the device can be directly removed from the frame.

[0035] Specifically, the connecting bracket 11 is provided with several connecting holes 12;

[0036] The connection hole 12 allows bolts or other fasteners to be passed through, thereby securely mounting the connection bracket 11 and the entire battery housing to the vehicle frame.

[0037] Multiple weight-reducing holes 30 are also provided at intervals along the length of the crossbeam 10 and the longitudinal beam 20.

[0038] The weight reduction hole 30 can reduce the overall weight of the frame and achieve lightweighting while ensuring structural strength. For new energy vehicles, the overall vehicle weight directly affects the range and energy consumption performance, so lightweighting is an important means to improve performance.

[0039] like Figure 4 , Figure 5 As shown, Figure 4 The diagram shown is a three-dimensional representation of the battery swapping frame in the embodiment. Figure 2 ; Figure 5 The diagram shown is a three-dimensional representation of the battery swapping frame in the embodiment. Figure 3 ;

[0040] Several reinforcing bars 40 are spaced apart on the inner side wall of the longitudinal beam 20.

[0041] Flexible reinforcing bars 50 are spaced apart on the inner side wall of the beam 10.

[0042] like Figure 6 , Figure 7 As shown, Figure 6 What is shown is Figure 5 Enlarged schematic diagram of the structure at point B in the diagram; Figure 7 The diagram shown is a schematic of the buffer rib assembly in the embodiment;

[0043] The end of the rib 40 near the battery body has a slope 41, and the width of the rib 40 gradually increases along the entry direction of the battery body.

[0044] The overall strength of the frame can be improved by setting the ribs 40, and the spaced ribs 40 create a gap between the battery body and the side wall of the longitudinal beam 20, thereby forming an air flow channel, which helps to dissipate the heat of the battery body.

[0045] The inclined surface 41 set on the rib 40 can play a guiding role, guiding the battery body to automatically center when entering the frame, reducing offset error.

[0046] Weight reduction holes 30 are also provided on the rib 40.

[0047] The flexible rib group 50 includes a plurality of ribs 51 arranged sequentially at intervals along the entry direction of the battery body, and the ribs 51 protrude from the inner sidewall of the crossbeam 10.

[0048] The end face of the second rib 51 near the battery body is arc-shaped, and the thickness of multiple second ribs 51 gradually increases along the entry direction of the battery body.

[0049] The flexible rib group 50 creates a gap between the battery body and the side wall of the crossbeam 10, forming an airflow channel that helps dissipate heat from the battery body.

[0050] The flexible rib group 50 also plays a guiding role when the battery body enters the frame. The arc-shaped end face serves as a guide slope, making it easier for the battery body to enter the frame during installation. In addition, multiple protruding ribs 51 of different thicknesses form a "step-like" guide. Ribs 51 of different thicknesses continuously correct the posture of the battery body during the insertion process, improving the installation accuracy of the battery body. Specifically, ribs 51 are made of flexible material, which undergoes elastic deformation when compressed, absorbing impact energy and reducing damage to the battery body.

[0051] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
