Description

Technical Field

[0001] This application relates to the field of battery frame technology for new energy sweeper vehicles, and for example, to a novel battery frame structure for a new energy sweeper vehicle. Background Technology

[0002] Currently, most new energy sweeper trucks on the market use a side-mounted battery frame structure, located on the left and right sides of the vehicle. Due to limited chassis space, this structure cannot further expand the battery capacity, directly resulting in a limited driving range (see attached). Figure 1 (As shown).

[0003] Existing new energy sweeper trucks have limited chassis space, and to prevent the risk of battery scratches due to low battery placement, a ground clearance of about 300mm is usually required. Therefore, the space available for battery placement is limited, and only four battery packs with a size of about 970*550*240mm (each pack has a capacity of about 35 kWh) can be installed.

[0004] In daily work applications, the existing new energy sweeper vehicles have a daily driving range of about 200km. With the current battery pack arrangement, the battery capacity can only provide a driving range of about 120-140km, which cannot meet the requirements of all-weather work and greatly affects work efficiency. Utility Model Content

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides a novel battery frame structure for a new energy sweeper vehicle. Without changing the existing hanging battery frame arrangement, a new battery frame structure is developed that can be arranged on the upper surface of the vehicle frame to expand the battery pack, thereby increasing the driving range.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A novel battery frame structure for a new energy sweeper truck includes a new battery frame, which mainly consists of a frame, protective plates, and a bracket. The frame is located between the front water tank and the chassis of the sweeper truck. A chassis is located at the rear of the sweeper truck, through which the front and rear water tanks are mounted for ground sweeping. The frame is a square frame structure, with its bottom fixedly connected to the top side of the chassis. The front water tank of the sweeper truck is fixedly mounted on the top side of the frame. The interior of the frame is used to house the new battery pack. The frame containing the new battery pack is fixed by the front water tank and the chassis. The new battery pack is connected in series with the original battery pack to power the sweeper truck. A bracket for housing the new battery pack is provided inside the frame, and the bracket is fixedly connected to the frame. The new battery pack is located on the top side of the bracket and is supported and fixed by the bracket. Protective plates are fixedly installed on both sides of the frame, which increase the protection of the new battery pack. To protect the vehicle from the impact of the water truck's start-stop cycle over extended periods, preventing the newly added battery pack from loosening, and to enhance the overall stability of the frame, several reinforcing rods are fixed to the outer side of each guard plate. The top of each reinforcing rod is fixedly connected to the side wall of the guard plate, and the bottom is fixedly connected to the corresponding top side of the vehicle frame with screws, thus achieving a fixed connection between the frame and the vehicle frame. Two sets of opposing first support arms are located on one side of the bottom of the frame, and two sets of opposing second support arms are located on the other side. The bottom ends of the first and second support arms are respectively fixedly connected to the side wall of the corresponding vehicle frame with bolts, further increasing the stability between the frame and the vehicle frame and ensuring sufficient support strength. The addition of a battery frame expands the space for the battery pack, thereby increasing the sweeper's range. The frame structure facilitates ventilation and heat dissipation, effectively preventing battery performance degradation.

[0009] Furthermore, the new battery pack has a side block on its side, which contacts the side of the bracket and is fixedly connected by screws. The new battery pack is fixed by the cooperation between the side block and the bracket.

[0010] Furthermore, the bracket includes crossbars and longitudinal bars. There are four longitudinal bars divided into two groups. Four crossbars are fixed at equal intervals between each group of longitudinal bars. The longitudinal bars and crossbars are combined to form two frame structures. Each frame structure can support one additional battery pack, so the bracket can support at least two additional battery packs.

[0011] Furthermore, two sets of median plates are fixedly installed at equal intervals at the bottom of the frame. The median plates correspond to the positions of the crossbars in the middle of the bracket. The distance between the two sets of median plates is adapted to the width of the frame. Each median plate includes a bent strip and a connecting bend. The cross-section of the bent strip and the connecting bend is a 90° bent structure. The top side of the bent strip is connected to the bottom side of the two sets of connecting bends by fixing screws. The sides of the connecting bends are fixedly connected to the sides of the corresponding crossbars by fixing screws, thereby further increasing the stability of the bracket. The sides of the bent strips are all fixedly connected to the corresponding sidewalls of the frame by fastening bolts, further making the connection between the frame and the frame more stable.

[0012] Furthermore, each of the protective plates is provided with several heat dissipation holes to increase ventilation and heat dissipation.

[0013] Furthermore, several connecting screw holes are provided on both sides of the top of the frame, and fixing screws are inserted into the connecting screw holes. The frame is fixedly connected to the bottom of the front water tank by fixing screws, thereby realizing the connection between the frame and the front water tank.

[0014] The present disclosure provides a novel battery frame structure for a new energy sweeper vehicle, which can achieve the following technical effects:

[0015] 1): This utility model expands the battery pack arrangement space by adding a battery frame, thereby accommodating the new battery pack and improving the range of the sweeper. The frame structure facilitates ventilation and heat dissipation, which can effectively prevent the battery performance from deteriorating.

[0016] 2): The frame of this utility model is connected to the vehicle frame and the front water tank by screws or bolts, which supports the maintenance or replacement of the battery in the future;

[0017] 3) This utility model has a simple structure, good assembly, low maintenance and manufacturing costs, high reliability, good interchangeability, and practical value.

[0032] A novel battery frame structure for a new energy sweeper vehicle includes a new battery frame 1, which mainly consists of a frame 17, a protective plate 11, and a bracket 3. The frame 17 is located between the front water tank 6 and the frame 4 of the sweeper vehicle 7. The frame 4 is located at the rear of the sweeper vehicle 7, through which the front water tank 6 and the rear water tank are mounted for ground sweeping. The frame 17 is a square frame structure and its bottom is fixedly connected to the top side of the frame 4. The front water tank 6 of the sweeper vehicle 7 is fixedly mounted on the frame 17. On the top side, the interior of the frame 17 is used to house the new battery pack 2. The frame 17, which houses the new battery pack 2, is fixed by the front water tank 6 and the frame 4 of the sweeper vehicle 7. The new battery pack 2 is connected in series with the original battery pack to power the sweeper vehicle 7. Several connecting screw holes 13 are opened on both sides of the top of the frame 17. Fixing screws 9 are inserted into the connecting screw holes 13. The frame 17 is fixedly connected to the bottom of the front water tank 6 by fixing screws 9, thus realizing the connection between the frame 17 and the front water tank 6.

[0033] The inner side of the frame 17 is provided with a bracket 3 for placing the new battery pack 2. The bracket 3 is fixedly connected to the frame 17. The new battery pack 2 is placed on the top side of the bracket 3. The bracket 3 supports and fixes the new battery pack 2. The side of the new battery pack 2 is provided with a side block 21. The side block 21 contacts the side of the bracket 3 and is fixedly connected by screws. The new battery pack 2 is fixed by the cooperation of the side block 21 and the bracket 3. The bracket 3 includes a horizontal bar 31 and a vertical bar 32. There are four vertical bars 32 divided into two groups. Four horizontal bars 31 are fixed at equal intervals between each group of vertical bars 32. The vertical bars 32 and the horizontal bars 31 are combined to form two frame structures. Each frame structure can support one new battery pack 2. Therefore, the bracket 3 can support at least two groups of new battery packs 2.

[0034] Two sets of interface plates 8 are fixedly and equidistantly at the bottom of the frame 17. The interface plates 8 correspond to the positions of the crossbars 31 in the middle of the bracket 3. The distance between the two sets of interface plates 8 is adapted to the width of the frame 4. Each interface plate 8 includes a bent strip 81 and a connecting bend 82. The cross-sections of the bent strip 81 and the connecting bend 82 are both 90° bent. The top side of the bent strip 81 is connected to the bottom side of the two sets of connecting bends 82 by fixing screws 9. The sides of the connecting bends 82 are fixedly connected to the sides of the corresponding crossbars 31 by fixing screws 9, thereby further increasing the stability of the bracket 3. The sides of the bent strip 81 are fixedly connected to the corresponding side wall of the frame 4 by fastening bolts 83, further making the connection between the frame 17 and the frame 4 more stable.

[0035] Both sides of the frame 17 are fixedly equipped with protective plates 11. These plates enhance protection for the new battery pack 2, preventing it from loosening after prolonged periods of starting and stopping due to the impact of the water truck. They also improve the overall stability of the frame 17. Each protective plate 11 has several ventilation holes 12 for increased airflow and heat dissipation. Several reinforcing rods 16 are fixedly installed on the outer side of each protective plate 11. The top of each reinforcing rod 16 is fixedly connected to the side wall of the protective plate 11, and the bottom is fixedly connected to the top side of the corresponding vehicle frame 4 with screws, thus achieving a fixed connection between the frame 17 and the vehicle frame 4. The bottom of the frame 17 has two sets of opposing first support arms 14 on one side and two sets of opposing second support arms 15 on the other side. The bottom ends of the first support arms 14 and the second support arms 15 are respectively fixed to the side wall of the corresponding vehicle frame 4 by bolts, thereby further increasing the stability between the frame 17 and the vehicle frame 4 and ensuring that the frame 17 has sufficient support strength. The addition of the battery frame 1 expands the space for the battery pack, thereby accommodating the new battery pack 2 and improving the range of the sweeper 7. The frame structure of the frame 17 facilitates ventilation and heat dissipation, which can effectively prevent the battery performance from degrading.
