Description

Technical Field

[0001] This utility model relates to the field of modular battery technology, and in particular to a battery box containing pluggable control components. Background Technology

[0002] With the increasing demand for highly reliable power supplies in fields such as special vehicles and mobile devices, modular battery packs are gradually becoming a core component of power systems due to their scalability, portability, and rapid maintenance capabilities. In existing technologies, modular battery packs typically employ a layered integration design, fixing battery modules and control devices such as the battery management system (BMS) within a housing to meet compact layout requirements. However, this design still has significant drawbacks in terms of assembly efficiency, maintenance flexibility, and functional expandability.

[0003] For example, the prior art disclosed in patent CN219801169U provides a modular battery pack that uses a horizontal support plate inside the casing to divide the space into upper and lower layers. The battery module is fixed to the upper layer, and the BMS is fixed to the lower layer, with installation and replacement completed through a side opening. Although this solution optimizes the wiring space through its layered structure, the following problems still exist:

[0004] 1. Inconvenient maintenance: Both the BMS and the battery module are fixedly installed. If it is necessary to repair or replace the control device, the entire battery pack must be disassembled, exposing the entire battery module and BMS. This method is cumbersome to operate and is prone to damaging the internal structure.

[0005] 2. Limited configuration: The control device and battery module are integrated into the same enclosure, making it impossible to flexibly replace or upgrade the control module according to different scenario requirements (e.g., different BMS versions).

[0006] 3. Space limitations: The layered stacking design means that the BMS and battery module share a side opening, and wiring still needs to be completed in a narrow space during installation, resulting in low operating efficiency. Utility Model Content

[0007] To address the aforementioned technical issues, and more specifically, to enable rapid plug-in / plug-out maintenance, independent configuration, and efficient installation of the control components of the battery module, this invention provides a battery box containing pluggable control components, thereby improving the reliability and scenario adaptability of the power system.

[0011] The supporting isolation component includes a partition plate and a guide groove disposed on the partition plate;

[0012] The pluggable control assembly includes a pull-out T-shaped plate, a positioning base plate fixed on the pull-out T-shaped plate, and a control module;

[0013] The pull-out T-shaped plate is provided with an inlet slide rail, which slides in conjunction with the guide groove, so that the pluggable control component is inserted into the front cavity through the front end slot and fixed, and the control module is electrically connected to the battery in the rear battery assembly cavity.

[0014] This invention separates the front and rear cavities by using a supporting separator, and allows the control components to be independently plugged in and unplugged via a sliding rail. This enables the individual and quick replacement of the control components or battery modules by handling the front and rear cavities separately, avoiding the problem of exposing the entire battery module and BMS, and preventing damage to internal structures that do not require treatment.

[0015] As a preferred embodiment of the aforementioned battery box, the guide groove is configured as a protruding structure of the partition, which is used to guide the slide rail after it is inserted into the guide groove, so that the distance between the slide rail and the partition is adjustable.

[0016] As a preferred embodiment of the aforementioned battery box, after the guide rail is inserted into the guide groove, it is fixed to the threaded hole of the pull-out T-shaped plate by bolts passing through the upper side wall of the box.

[0017] As a preferred embodiment of the aforementioned battery box, at least a portion of the vertical projection of the guide groove's opening overlaps with the slot in the box body, for inserting the guide rail through the slot into the guide groove.

[0018] As a preferred embodiment of the aforementioned battery box, the grooved edge of the front cavity is provided with a sealing strip, and the contact surface between the pull-out T-shaped plate and the groove is provided with a waterproof rubber ring.

[0019] As a preferred embodiment of the aforementioned battery box, the control module includes at least one of a BMS, a power management unit, or a communication module, and is connected to the battery in the rear battery assembly cavity via a plug-in terminal.

[0020] As a preferred embodiment of the above-mentioned battery box, the positioning base plate is provided with heat dissipation holes, and a cooling fan is provided at a corresponding position on the inner wall of the front cavity of the box.

[0021] As a preferred embodiment of the aforementioned battery box, the bottom of the rear battery assembly cavity of the box is provided with a battery fixing buckle, and the battery is pushed into the cavity through a slide rail structure and limited by the buckle.

[0022] As a preferred embodiment of the aforementioned battery box, the front outer wall of the box is provided with a quick-release handle, which is linked to the pull-out T-shaped plate, and the bolt fixing state is unlocked when the handle is pulled.

[0023] As a preferred embodiment of the above-mentioned battery box, an elastic limiting block is provided in the guide groove, and the end of the guide rail of the pull-out T-shaped plate is provided with a groove that engages with the elastic limiting block.

When the control module is connected to the battery in the rear battery assembly cavity by wires, a certain distance can be formed so that a reserved wire is loaded in the front cavity. The reserved wire can be used to plug and replace the control component after the guide rail is pulled out of the groove, avoiding the wire being scratched when plugged in under tension.

[0028] (4) The guide groove of this utility model is set as a protruding structure of the partition. The battery box of this utility model can complete the wiring outside the battery box during installation, which has high operation efficiency.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0037] Example 1

[0038] This embodiment provides a battery box including a pluggable control component 202, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it includes at least a housing 1 and a pluggable control assembly 202, and also includes:

[0039] The front end of the housing 1 is provided with a slot 101, and the interior of the housing 1 is divided into a front cavity and a rear battery assembly cavity by a supporting isolation member 201.

[0040] The supporting isolation member 201 includes a partition plate 20101 and a guide groove 20102 disposed on the partition plate 20101;

[0041] The pluggable control assembly 202 includes a pull-out T-shaped plate 20203, a positioning base plate 20202 fixed on the pull-out T-shaped plate 20203, and a control module 20201;

[0042] The pull-out T-shaped plate 20203 is provided with an inlet slide rail 20204. The inlet slide rail 20204 slides in conjunction with the guide groove 20102, so that the pluggable control component 202 is inserted into the front cavity through the front end slot 101 and fixed, and the control module 20201 is electrically connected to the battery in the rear battery assembly cavity.

[0043] By separating the front and rear cavities with the support separator 201, the control components can be independently plugged in and out using a sliding rail pull-out design. This allows for the separate and quick replacement of the control components or battery modules by handling the front and rear cavities separately, avoiding the problem of exposing the entire battery module and BMS, and preventing damage to internal structures that do not require treatment.

[0044] like Figure 4 As shown, the guide groove 20102 is configured as a protruding structure of the partition 20101, which is used to guide the slide rail 20204 after it is inserted into the guide groove 20102, so that the distance between the slide rail 20204 and the partition 20101 is adjustable.

[0045] The guide groove 20102 is designed as a protruding structure of the partition 20101, creating a certain front-to-back space within the guide groove 20102. After the guide rail 20204 is inserted into the guide groove 20102, the guide rail 20204 can be positioned at a certain distance from the partition 20101 as needed, and this distance is adjustable. When the control module 20201 is connected to the battery in the rear battery assembly cavity via wires, a certain distance can be created to allow for the installation of pre-installed wires in the front cavity. These pre-installed wires can be used for plugging and replacing control components after the guide rail 20204 is pulled out of the slot 101, avoiding damage to the wires caused by plugging them in a taut state.

[0046] In a preferred embodiment, after the guide rail 20204 is inserted into the guide groove 20102, it is fixed to the threaded hole of the pull-out T-shaped plate 20203 by bolts passing through the upper side wall of the housing 1.

[0047] The bolts pass through the mounting holes on the upper side wall of the housing 1 and are fixed to the threaded holes of the pull-out T-shaped plate 20203. Because the bolts pass through the housing 1, the pull-out T-shaped plate 20203 and its control components can rely on the stability of the housing 1 to improve their fixing effect. As a preferred embodiment, the front outer wall of the housing 1 is provided with a quick-release handle. Pulling the handle will release the bolts, facilitating quick disassembly.

[0048] In a preferred embodiment, at least a portion of the vertical projection of the opening of the guide groove 20102 overlaps with the slot 101 of the housing 1, for inserting the guide rail 20204 through the slot 101 into the guide groove 20102. This means that the guide rail 20204 can be inserted vertically into the slot 101 and then into the guide groove 20102, and from a top view, a portion of the guide groove 20102 may be invisible. The portion overlapping the slot 101 of the housing 1 is related to the length of the protrusion of the guide groove 20102 on the partition 20101.

[0049] As a preferred embodiment, the groove 101 of the front cavity is provided with a sealing strip at its edge, and a waterproof rubber ring is provided on the contact surface between the pull-out T-shaped plate 20203 and the groove 101 to improve the protection level.

[0050] As a preferred embodiment, the control module 20201 includes at least one of a BMS, a power management unit, or a communication module, and is connected to the battery in the rear battery assembly cavity via a plug-in terminal.

[0051] As a preferred embodiment, the positioning base plate 20202 is provided with heat dissipation holes, and a heat dissipation fan is provided at a corresponding position on the inner wall of the front cavity of the housing 1.

[0052] As a preferred embodiment, the bottom of the rear battery assembly cavity of the housing 1 is provided with a slide rail structure and a battery fixing buckle. When the modular lithium battery pack is pushed into the cavity along the slide rail, the buckle automatically limits and locks in place.

[0053] As a preferred embodiment, an elastic limiting block is provided in the guide groove 20102, and the end of the guide rail 20204 of the pull-out T-shaped plate 20203 is provided with a groove that engages with the elastic limiting block.

[0054] When the control components are replaced, the pluggable control component 202 is pushed into the slot 101 at the front end of the housing 1, the guide rail 20204 is inserted into the guide groove 20102 and slid to the end, and the elastic limit block engages with the groove to complete the pre-positioning, which helps to make the installation more stable and the fixing effect better during and after installation.

[0055] Compared with the prior art, the beneficial effects of the battery box provided in this embodiment are:

[0056] (1) The front and rear cavities are separated by vertically set support isolation parts. The control components are independently plugged in and unplugged by sliding rail pull-out. The control components or battery modules can be replaced separately and quickly by handling the front and rear cavities separately, avoiding the problem of exposing the entire battery module and BMS, and avoiding the problem of damage to the internal structure that does not need to be handled.

[0057] (2) Due to the physical isolation and quick replacement of the battery and control module in this battery box, this battery box can flexibly replace or upgrade different versions of the control module according to different scenario requirements, and realize configuration diversity; it can adapt to different versions of the control module, meet the diverse needs of special vehicle power cabinets, and the technical effect is significantly better than the existing layered fixed structure.

[0058] (3) The guide groove of this battery box is set as a raised structure of the partition, so that a certain front and back space is formed in the guide groove. After the guide rail is inserted into the guide groove, the guide rail can form a certain distance with the partition as needed, and this distance is adjustable. When the control module is connected to the battery in the rear battery assembly cavity by wires, a certain distance can be formed so that a reserved wire is loaded in the front cavity. The reserved wire can be used to plug and replace the control component after the guide rail is pulled out of the slot, avoiding the wire being scratched when plugged in under tension.

[0059] (4) The guide groove of this battery box is set as a raised structure of the partition. This battery box can complete the wiring outside the battery box during installation, which is highly efficient.

[0060] (5) The physical size of the control component is generally smaller than that of the battery. The front cavity of the battery box used to install the control component can be set according to the physical size of the control component, which is conducive to reducing the overall size of the battery box and saving space.
