Description

Technical Field

[0001] This utility model relates to the field of vehicle structural components technology, and in particular to a floor assembly with an inspection port. Background Technology

[0002] Box trucks, containers, or similar enclosed box structures typically use an integral floor assembly. Traditional floor assemblies are generally made by welding or bolting the box frame to a single floor plate. After installation, the floor plate forms a closed load-bearing surface to support the goods or equipment inside the box. This structure is simple in design, has high strength, and can meet the basic load-bearing requirements of daily transportation and use.

[0003] In practice, some problems still exist:

[0004] With the widespread application of electric vehicles, the safety and ease of maintenance of battery packs, as the core power source of the vehicle, are receiving increasing attention. Traditional electric vehicle floor panels usually adopt an integral structure design, with the floor panel fixedly connected to the bottom of the body. The overall structure is sealed and has high strength, but it lacks reserved passages for easy maintenance. This means that when the battery fails or needs to be replaced, maintenance personnel can only operate by disassembling the entire floor panel or side door. The disassembly and assembly process is cumbersome and time-consuming, which seriously affects maintenance efficiency and the normal uptime of the vehicle.

[0005] In addition, the battery fixing method in traditional base plate structures is relatively simple, usually using a straight support beam design, which is difficult to adapt to the diverse specifications of battery packs on the market and cannot meet the installation requirements of different battery sizes. This can easily lead to unstable installation or require repeated design of base plate structures for different battery models, increasing manufacturing costs and design difficulty. At the same time, batteries are prone to safety hazards due to vibration and displacement during vehicle operation, and existing technologies lack effective structural measures to solve this problem. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the aforementioned problems in the prior art, this utility model provides a base plate assembly with an inspection port, which solves the problems of difficult maintenance of electric vehicle batteries, simple fixing structure, and low safety and maintenance efficiency.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the main technical solution adopted by this utility model is as follows:

[0010] A floor assembly with an inspection port includes a body, a connecting floor plate fixedly connected to the bottom end of the body, a load-bearing frame fixedly connected to the bottom end of the connecting floor plate, an inspection port provided in the middle of the load-bearing frame, an inspection sealing plate detachably snapped into the middle of the inspection port, a storage handle installed at the top of the inspection sealing plate, and the size of the inspection sealing plate matching the size of the inspection port.

[0011] A door is hinged to one side of the compartment, and an upward-opening door is also hinged to one side of the compartment. The maximum opening angle of the upward-opening door is 90 degrees, thereby expanding the cargo handling passage.

[0012] A load-bearing frame is fixedly connected to the bottom of the connecting base plate, and rectangular tubes are fixedly connected to the four corners of the top of the load-bearing frame, and the four rectangular tubes are respectively inserted into the uprights of the box body.

[0013] The inner wall of the load-bearing frame is fixedly connected to a crossbeam, and the crossbeam is fixedly connected to a first longitudinal beam. A second longitudinal beam is stacked below the first longitudinal beam, thereby forming a height space for placing the battery pack.

[0014] The bottom end of the connecting base plate is fixedly connected to a U-shaped connector, and the first longitudinal beam and the second longitudinal beam are placed inside the U-shaped connector to provide reinforcement.

[0015] A connecting hinge is provided for the fixed connection between the first longitudinal beam and the cross beam, and a stabilizing member is provided for the connection between the first longitudinal beam and the second longitudinal beam. The connecting hinge and the stabilizing member serve to further tighten the connection.

[0016] The bottom end of the maintenance enclosure plate is fixedly connected with a reinforcing rib, and there are four handles symmetrically located at the top of the maintenance enclosure plate.

[0017] (III) Beneficial Effects

[0018] The beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting up components such as inspection ports, connecting flaps, and handles, a convenient and quick maintenance channel can be provided without affecting the overall strength of the base plate. The maintenance sealing plate is connected to the inspection port by a snap-fit ​​method, so that the base plate still has sealing and protective performance when the electric vehicle is in normal operation. When the battery needs to be inspected, the staff can quickly remove the maintenance sealing plate and directly access the battery through the reserved inspection port. Compared with the traditional one-piece base plate, which must be maintained through the side door or by disassembling the entire base plate, this design significantly reduces the disassembly and assembly steps, saves maintenance time and labor costs, and improves the operation and maintenance efficiency of electric vehicles.

[0020] 2. In this utility model, the special arrangement of the load-bearing frame, the first longitudinal beam, and the second longitudinal beam allows the battery to be reliably secured between the two sets of longitudinal beams. Both the first and second longitudinal beams adopt irregular structures, which can accommodate batteries of different specifications and sizes, avoiding the need for repeated design of the base plate due to differences in battery models. The U-shaped connector and the stabilizing component work together to limit and reinforce the first and second longitudinal beams, ensuring that the battery will not loosen, shift, or vibrate excessively during vehicle operation, significantly improving the reliability and safety of battery fixation. This structure not only optimizes the space utilization of the vehicle base plate but also enhances the adaptability and ease of maintenance of the entire vehicle. Attached Figure Description

[0030] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please refer to Figures 1 to 7As shown, the present invention provides a bottom plate assembly with an inspection port, including a body 2, a connecting bottom plate 3 fixedly connected to the bottom end of the body 2, a load-bearing frame 14 fixedly connected to the bottom end of the connecting bottom plate 3, an inspection port 12 opened in the middle of the load-bearing frame 14, an inspection sealing plate 9 detachably snapped into the middle of the inspection port 12, a storage handle 10 installed at the top of the inspection sealing plate 9, and the size of the inspection sealing plate 9 matches the size of the inspection port 12.

[0032] In actual implementation, the bottom of the body 2 is fixedly connected to the connecting base plate 3 by riveting. The middle of the connecting base plate 3 is pre-opened with an inspection port 12. The inspection port 12 is detachably connected to the inspection sealing plate 9. The inspection sealing plate 9 and the inspection port 12 are matched in size. When the electric vehicle is running, the base plate maintains the overall load-bearing and sealing performance. When the battery needs to be repaired or replaced, the staff can loosen the locking structure and directly remove the inspection sealing plate 9 by pulling the storage handle 10. The battery placed between the longitudinal beams can then be inspected, disassembled or installed through the inspection port 12, which significantly reduces disassembly and assembly time and improves maintenance efficiency and safety.

[0033] Optionally, a hinged top-opening door 1 is provided on one side of the compartment 2. The top-opening door 1 has a maximum opening angle of 90 degrees, thereby expanding the cargo handling passage.

[0034] In actual implementation, when inspecting the battery, staff can first open the compartment door 1 to obtain additional operating space, then grab the handle 10 and easily remove or reinstall the inspection and sealing plate 9. The whole process does not require complicated tools, making it easy for a single person to operate. This improves the flexibility and convenience of inspecting the battery at the bottom of the electric vehicle, reduces working time and labor intensity, and ensures the rapid maintenance needs of the electric vehicle under different working conditions.

[0035] Optionally, rectangular tubes 13 are fixedly connected to the four corners of the top of the load-bearing frame 14, and the four rectangular tubes 13 are respectively inserted into the columns of the box body 2. In actual implementation, this structure allows the load-bearing frame 14 to evenly distribute the load of the bottom plate during operation, the rectangular tubes 13 prevent the load-bearing frame 14 from shifting relative to the box body 2, and the entire bottom plate assembly forms a stable whole, which can adapt to the impact of electric vehicles during driving and load changes, significantly improving the strength and durability of the bottom plate and reducing the frequency of later maintenance.

[0036] Optionally, a crossbeam 6 is fixedly connected to the inner wall of the load-bearing frame 14, and a first longitudinal beam 4 is fixedly connected to the crossbeam 6. A second longitudinal beam 5 is stacked below the first longitudinal beam 4, thus forming a height space for placing the battery pack. A U-shaped connector 11 is fixedly connected to the bottom end of the connecting base plate 3, and the first longitudinal beam 4 and the second longitudinal beam 5 are placed inside the U-shaped connector 11 for reinforcement. In actual implementation, a battery placement space is formed between the two sets of longitudinal beams. During maintenance, staff can directly operate the battery through the inspection port 12. The limiting structure formed by the longitudinal beams and the U-shaped connector 11 keeps the battery stable during driving, reducing the risk of shaking and falling off, and ensuring the safe operation of the electric vehicle.

[0037] Optionally, a connecting plate 7 is used to fix the first longitudinal beam 4 and the cross beam 6, and a stabilizing member 8 is used to connect the first longitudinal beam 4 and the second longitudinal beam 5. The connecting plate 7 and the stabilizing member 8 serve to further tighten the connection. In actual implementation, the connecting plate 7 improves the load-bearing and impact resistance of the longitudinal beams, while the stabilizing member 8 ensures that the spacing and position of the longitudinal beams do not shift. This allows the battery to remain stable under high-frequency vibration and complex operating conditions after it is installed, extending the service life of the battery and the base plate assembly, and improving the overall operational reliability and maintenance convenience of the electric vehicle.

[0038] Optionally, a reinforcing rib 15 is fixedly connected to the bottom end of the maintenance enclosure plate 9, and four handles 10 are symmetrically located at the top of the maintenance enclosure plate 9. In actual implementation, the reinforcing rib 15 fixedly connected to the bottom end of the maintenance enclosure plate 9 forms multiple longitudinal and transverse supports, which can effectively distribute external loads and vibrations, prevent the maintenance enclosure plate 9 from deforming or cracking after frequent disassembly and assembly and long-term load-bearing, ensure that the maintenance enclosure plate 9 continues to maintain its seal and strength, improve the durability of the electric vehicle floor assembly in daily operation and maintenance, reduce the frequency of replacement, and further optimize the later maintenance experience and use safety of electric vehicles.

[0039] Working principle: First, the bottom of the body 2 is riveted to the connecting base plate 3, forming a robust closed structure with the body 2. An inspection port 12 is pre-drilled in the middle of the connecting base plate 3. The inspection port 12 is detachably connected to the inspection sealing plate 9 via a snap-fit ​​structure. The dimensions of the inspection sealing plate 9 match those of the inspection port 12, ensuring good sealing and load-bearing performance when closed. When the electric vehicle is in normal operation, the load-bearing frame 14 and the connecting base plate 3 share the structural load at the bottom. Rectangular tubes 13 are fixed at the four corners of the load-bearing frame 14 and connected to the bottom of the body 2, ensuring the overall structure remains stable under stress. A horizontal... Beam 6 connects to the bottom of the base plate 3 and is connected to a U-shaped connector 11. The first longitudinal beam 4, the U-shaped connector 11, and the second longitudinal beam 5 form a clamping space for placing the battery. When the battery is installed, it is clamped between the two sets of longitudinal beams. The irregularly shaped longitudinal beams can accommodate batteries of different sizes. The U-shaped connector 11 and the stabilizing member 8 together limit the first longitudinal beam 4 and the second longitudinal beam 5 to ensure that the battery does not shift during operation. When the battery needs to be repaired or replaced, the staff only needs to open the inspection sealing plate 9 and can directly disassemble, inspect, and replace the battery through the inspection port 12. The whole process does not require disassembling the entire base plate or lifting the whole vehicle, which greatly improves the convenience and efficiency of maintenance operations.

All standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all adopt conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art.
