Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery installation structure technology, and in particular to a battery press-fit structure. Background Technology

[0002] Electric vehicles are mainly divided into electric bicycles and electric motorcycles. As consumer demand continues to increase, the battery capacity and specifications of electric vehicles are also increasing, and the existing structure can no longer meet market demand.

[0003] The battery box mounting structure on an electric vehicle uses the battery box frame to limit the battery body in all directions, with pressure strips to prevent the battery from moving around. It can only be equipped with batteries of a specified specification. If the battery specification is changed, the battery box frame will no longer have the function of limiting the battery when the vehicle is in harsh driving conditions. This will cause the battery to swing freely. When the battery swings freely and the positive terminal comes into contact with the pressure strip or the frame, the positive and negative terminals of the battery will be grounded, causing the battery to catch fire and endangering driving safety. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a battery press-fitting structure that is applicable to battery packs of different specifications and installation methods. It provides multi-directional reliable limiters for each type of battery pack to ensure the relative positional stability of the battery during riding and parking.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A battery press-fit structure is used in the battery compartment of an electric vehicle. A high-voltage regulating strip is installed near the front of the battery compartment, a transverse press-fit strip is press-fitted in the middle of the battery compartment, and a limiting plate assembly is configured near the rear of the battery compartment.

[0007] The pressure regulating strip, transverse pressure strip, and limit plate assembly are all detachably connected to the vehicle frame.

[0008] The high-voltage regulating bar is a detachable assembly used to compensate for the height difference between the battery pack and the battery compartment.

[0009] The limiting plate assembly provides limiting force to the battery pack in at least one direction.

[0010] As a further improvement to the above technical solution:

[0011] The voltage regulating bar includes:

[0012] The connecting bracket is detachably connected to the vehicle frame.

[0013] The crossbeam is clamped and connected to the connecting bracket with a snap-fit ​​mechanism, and it abuts against the top of the battery pack.

[0014] The connecting brackets or clamping beams are available in various specifications.

[0015] The connecting bracket has a bent structure, with the bent section facing the battery pack, and the snap-fit ​​connection is located at the end of the bent section.

[0016] Multiple snap-fit ​​connection points are set on the clamping beam to match the connecting bracket.

[0017] The connecting bracket is provided with a first connecting hole, and the frame is provided with a plurality of second connecting holes that are adapted to the first connecting hole; the second connecting holes are arranged in an array in at least one direction.

[0018] A transverse strip consists of two perpendicular steel sections.

[0019] In the limit plate assembly, each limit plate includes:

[0020] The limiting plate is flat against the mounting surface.

[0021] The limiting plate is set perpendicular to the limiting plate and abuts against the side wall of the battery pack.

[0022] The locations where the limit plate is set include:

[0023] It is pressed against the side wall of the battery pack near the rear of the vehicle.

[0024] Or simultaneously, it comes into contact with multiple sidewalls of the battery pack.

[0025] Suitable for battery packs with full-load pressure limit or battery packs partially installed within the battery compartment.

[0026] The beneficial effects of this utility model are as follows:

[0027] This utility model equips the battery compartment with three sets of limiting structures. Among them, the high-voltage strip and the transverse strip are used to press the battery from top to bottom to prevent the battery pack from moving upward and hitting the pedal and supporting the driver. The limiting plate group is connected to the battery fixing plate on the vehicle body to prevent the battery from moving in the front, back and left and right directions when switching between different battery specifications, which could cause the battery terminals to collide with the battery strip, and thus cause the battery to short circuit with the electric vehicle, damage the battery, or cause the electric vehicle to catch fire.

[0028] The high voltage adjustment strip and the transverse pressure strip are detachably connected to the frame, and the limit plate assembly is detachably connected to the battery fixing plate.

[0029] The high-voltage adjustment strip, transverse pressure strip, and limit plate assembly not only restrict battery movement but also effectively fix and limit the battery, thereby preventing short circuits caused by installing batteries of different specifications in electric vehicles, ensuring the lifespan of the pedals and the electric vehicle, and thus extending the service life of the electric vehicle.

[0038] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0039] like Figures 1-4 As shown, the battery press-fit structure of this embodiment is applied to the battery compartment 1 of an electric vehicle. A high-voltage regulating strip 2 is installed near the front of the battery compartment 1, a transverse pressing strip 3 is press-fitted in the middle of the battery compartment 1, and a limiting plate assembly 4 is configured near the rear of the battery compartment 1.

[0040] The high-pressure adjusting strip 2, the transverse pressure strip 3, and the limiting plate assembly 4 are all detachably connected to the vehicle frame.

[0041] The high-voltage regulating strip 2 is a detachable assembly used to compensate for the height difference between the battery pack 5 and the battery compartment 1.

[0042] The limiting plate group 4 provides a limiting force to the battery pack 5 in at least one direction.

[0043] High voltage regulator bar 2 includes:

[0044] Connecting bracket 201 is detachably connected to the vehicle frame.

[0045] The crossbeam 202 is snapped together with the connecting bracket 201 and abuts against the top of the battery pack 5.

[0046] The connecting bracket 201 or the clamping beam 202 is available in various specifications.

[0047] The connecting bracket 201 has a bent structure, with the bent section facing the direction of the battery pack 5, and the buckle connection position is located at the end of the bent section.

[0048] Multiple snap-fit ​​connection points are provided on the clamping beam 202 to match the connecting bracket 201.

[0049] The connecting bracket 201 is provided with a first connecting hole 203, and the frame is provided with a plurality of second connecting holes 101 that are adapted to the first connecting hole 203; the second connecting holes 101 are arranged in an array in at least one direction.

[0050] The transverse pressure strip 3 consists of two mutually perpendicular steel sections.

[0051] In the limit plate group 4, each limit plate includes:

[0052] The limiting plate 401 is flat against the mounting surface.

[0053] The limiting plate 402 is set perpendicular to the limiting plate 401 and abuts against the side wall of the battery pack 5.

[0054] The locations where the limit plate is set include:

[0055] It is in contact with the side wall of battery pack 5 near the rear of the vehicle.

[0056] Or simultaneously abut against multiple sidewalls of battery pack 5.

[0057] It is applicable to battery packs 5 that are fully loaded with pressure-fitted limit devices, or battery packs 5 that are partially installed in battery compartment 1.

[0058] The specific structure and pressing steps of this utility model are as follows:

[0059] like Figure 1 As shown, in one embodiment of this utility model, a plurality of battery packs 5 are arranged in parallel within a cubic battery compartment 1. These battery packs 5 completely fill the battery compartment 1. At this time, the high-voltage regulating strip 2, the transverse pressure strip 3, and the limiting plate group 4 are respectively pressed against the side of the battery compartment 1 near the front of the vehicle, the middle section of the battery compartment 1, and the side of the battery compartment 1 near the rear of the vehicle. The limiting plate group 4 can be used or not, because under this installation condition, the battery packs 5 are fully limited, ensuring that they do not move during driving and parking.

[0060] like Figure 2As shown, in another embodiment of this utility model, a set of battery packs 5 is installed near the left side of the cubic battery compartment 1 according to the orientation shown in the figure. In this case, the high-voltage adjusting strip 2, the transverse pressure strip 3, and the limiting plate group 4 must work together. The high-voltage adjusting strip 2 applies a downward limiting force, the transverse pressure strip 3 applies a downward limiting force, and the limiting plate group 4 provides a limiting force pointing towards the side wall of the battery pack 5. The side wall of the battery compartment 1 also provides a limiting force pointing towards the battery pack 5. The limiting plate group 4 can consist of one or more limiting plates, with a maximum of six limiting plates. The six limiting plates are located at different side walls of the battery pack 5.

[0061] The structure of the high-pressure regulating bar 2 of this utility model is as follows: Figure 3 As shown, the high-voltage regulating bar 2 has a split structure, including a connecting bracket 201 and a clamping crossbeam 202. Most of the connecting bracket 201 is a straight rod parallel to the top surface of the battery pack 5. One end of the rod is securely connected to the vehicle frame, and the other end is bent vertically downwards and fitted with a buckle, which is then snapped into the clamping crossbeam 202. There are multiple mounting points between the vehicle frame and the connecting bracket 201, and also multiple mounting points between the connecting bracket 201 and the clamping crossbeam 202, allowing for multiple mounting methods to maximize the contact area with the top of the battery pack 5. For example, if the battery pack 5 is installed on the left side of the battery compartment 1, the connecting bracket 201 is also installed at a left-side mounting point, and the clamping crossbeam 202 is connected to the connecting bracket 201 via a right-side snap-fit ​​point to maximize the contact area between the clamping crossbeam 202 and the battery pack 5.

[0062] The transverse pressure strip 3 structure of this utility model is as follows: Figure 1 As shown, two perpendicular steel sections are used, with the crossbeam above the battery compartment 1 being detachably mounted to the vehicle frame; and the steel section along the line connecting the front and rear of the vehicle is...

[0063] The limiting plate structure of this utility model is as follows: Figure 4 As shown, it is used in conjunction with the battery mounting plate 6 at the battery compartment 1. The battery mounting plate 6 is connected to the vehicle frame and is located on the outside of the battery pack 5. The limiting plate is connected to the horizontally set battery mounting plate 6 to prevent the battery pack 5 from shifting in the front-back and left-right directions when switching between different battery specifications in the electric vehicle. It also prevents the battery terminals from colliding with the high voltage regulating bar 2 and the transverse pressure bar 3, which could lead to a short circuit between the battery pack 5 and the electric vehicle, damage to the battery pack 5, or fire in the electric vehicle.

[0064] Each limiting plate has mounting holes located on the limiting plate 401. Using fasteners such as screws, the limiting plate 401 is detachably mounted on the battery mounting plate 6.

[0065] The limiting plate 402 of the limiting plate can be a single piece or a door post, as long as it can provide a limiting force against the battery pack 5.

[0066] This invention can effectively limit the use of batteries of various specifications, ensuring the lifespan of the pedals and electric vehicles, thereby extending the overall service life of the electric vehicle.

[0067] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
