Description

Technical Field

[0001] This utility model relates to the technical field of motorcycles, and in particular to a battery frame for converting gasoline batteries to electric power. Background Technology

[0002] Traditional gasoline-powered vehicles have irregularly shaped fuel tank compartments with low space utilization and no pre-installed high-voltage wiring harness channels or heat dissipation structures. Directly assembling battery cells into the original fuel tank compartment presents the following drawbacks: Without dedicated mounting points, the battery pack requires additional welding brackets, making the modification process complex and damaging to the vehicle body; The wires are suspended in the air, making them prone to wear and short circuits when the vehicle is bumpy. The arrangement of battery cells is restricted by the "step-sloping surface" at the bottom of the fuel tank, resulting in large gaps and low energy density; Insufficient sealing and heat dissipation lead to a high risk of thermal runaway and a shortened lifespan. Utility Model Content

[0003] Purpose of the invention: The purpose of this utility model is to provide a battery frame for converting oil-to-electric batteries, thereby solving the above-mentioned problems. Technical solution

[0004] A battery frame for converting oil-to-electricity batteries includes an outer shell, an inner cavity for accommodating battery cells, a plurality of fixing brackets on the side wall of the cavity, and a power supply wire on the inner wall of the outer shell. The two ends of the power supply wire are respectively connected to a socket, the socket is fixed and passes through the outer shell, and the power supply wire passes through the fixing bracket.

[0005] Preferably, the accommodating cavity is provided with a stepped groove and an inclined surface, with the stepped groove and the inclined surface facing each other.

[0006] In this embodiment, the stepped grooves and ramps completely replicate the stepped-rammed geometry of the crude oil tank, improving space utilization and allowing the battery cells to be stacked in a "stepped" manner.

[0007] Preferably, the bottom of the outer casing is provided with a mounting cavity corresponding to the stepped groove.

[0008] Preferably, the outer casing also includes a plurality of connecting pieces for connecting the vehicle frame on its peripheral surface, and the connecting pieces are arranged in an array on the peripheral surface of the outer casing.

[0009] It directly utilizes the original fuel tank mounting holes, eliminating the need for welding / drilling, reducing the intensity of modification, and maintaining the original strength of the vehicle body.

[0010] Preferably, the connecting pieces are arranged in pairs, and the connecting pieces are connected to the frame in the same direction.

[0011] Preferably, the outer casing has an opening at the top of the accommodating cavity, and the outer casing has a sealing cap at the opening.

[0012] Preferably, handles are provided on both side walls of the housing.

[0013] Preferably, the inner wall of the outer casing is provided with a through heat dissipation vent, and the heat dissipation vent is provided with a filter screen.

[0014] Beneficial effects: This battery frame is designed for "oil-to-electric" conversion scenarios. It utilizes the irregular space of the original vehicle's fuel tank and features a stepped groove-sloping face matching, an overall top opening, array connecting pieces, and an internal wiring harness fixing bracket. The fixing bracket simultaneously constrains the battery cells and wiring harness, preventing wire shaking and wear, and reducing the risk of short circuits. The plug-and-play interface simplifies on-site wiring for oil-to-electric conversion. Attached Figure Description

[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0017] like Figure 1 , Figure 2 As shown, the battery frame 10 includes a housing 1, which is made of 2 mm thick high-strength aluminum-magnesium alloy plate bent and welded. Its external dimensions are close to the original fuel tank envelope, and it can be directly suspended under the original vehicle longitudinal beam. An accommodating cavity 11 is formed inside the housing 1 to accommodate and position the battery cell module. The top of the housing 1 has an opening 12, and a 10 mm wide sealing step 121 is milled around the opening 12. The sealing cover 13 is pressed against the step 121 with a sealing ring 15 by stainless steel bolts to achieve an IP67 protection rating.

[0018] Several fixing frames 16 are integrally extruded on the left and right side walls of the accommodating cavity 11. The fixing frames 16 are strip-shaped. In this embodiment, there are three fixing frames on each side, corresponding to the mounting holes of commercially available standard long battery cell modules. The power supply wire 17 is made of high-temperature silicone rubber and runs along the inner wall of the outer shell 1. It is fixed to the side of the fixing frame 16 at intervals by high-temperature resistant PPS clips to avoid direct contact with the battery cell. After the two ends of the wire 17 are crimped with copper terminals, they are connected to the quick-connect high-voltage socket 18. The socket 18 is fixed to the side wall of the outer shell 1 by a flange seat. A fluororubber sealing ring is provided between the flange seat and the shell to ensure a seal at the penetration point of the socket 18.

[0019] A stepped groove 19 is integrally cast at the bottom front end of the accommodating cavity 11. The stepped groove 19 is used to support the front aluminum bracket of the battery cell module. A corresponding inclined surface 20 is provided at the rear end, which can slide and cooperate with the rear guide chamfer of the module to achieve "push-in-fall" quick positioning. The stepped groove 19 and the inclined surface 20 are arranged opposite each other, which can form a self-locking mechanism when the vehicle is bumpy to prevent the module from moving back and forth.

[0020] The outer bottom of the outer shell 1 is recessed inward at the position corresponding to the stepped groove 19 to form a mounting cavity 21, which is used to accommodate the motor mechanism of the modified motorcycle and avoid cutting the chassis during modification.

[0021] Three pairs of connecting pieces 22 are punched outwards from each of the left and right sides of the outer shell 1. They are integrally formed from the same material and batch as the outer shell 1, and the surface is milled with waist-shaped holes that are completely consistent with the original vehicle's fuel tank strap mounting holes. The three pairs of connecting pieces 22 are arranged in a longitudinal array along the outer shell 1 to ensure uniform force distribution. Each pair of connecting pieces 22 is parallel vertically and has the same opening direction, all facing outwards from the vehicle, which facilitates rigid connection with the frame longitudinal beams and the original vehicle straps, reusing the original vehicle's force path without the need for additional supports. At the same time, the whole assembly can slide along the side of the frame for easy installation.

[0022] Handles 23 are welded to the middle of the left and right side walls of the outer shell 1. The handles 23 are made of stainless steel round tubes with knurled surfaces, making them easy for one or two people to lift.

[0023] A heat dissipation vent 24 is provided on the rear wall of the outer casing 1. A stainless steel filter 25 is fixed to the inside of the heat dissipation vent 24 by laser welding. This can prevent the intake of gravel and ensure natural cooling of the battery cell. The filter 25 is flush with the inner wall of the casing and does not occupy the space of the accommodating cavity 11.

[0024] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
