Description

A kind of modular battery box of linkage self-locking

Technical field

The utility model belongs to electric automobiles, is related to the battery case of electric vehicle, especially a kind of module of linkage self-locking Electrochemical cell box.

Background technique

Currently, the form that the locking of battery case is usual or traditional, i.e., directly produce buttonhole on battery box, locking Installation key is buckled, the locking to battery is achieved in.With the technological innovation of battery case, modular battery box is increasingly substituted This traditional battery case becomes exquisite, and battery capacity is high, but requires stability good, otherwise will affect the use of battery, even It may further result in the dislocation of battery and influence to use.Battery in existing modular battery box still uses traditional structure, It is not very rationally, to cause the stability test in battery case poor.

By the retrieval of publication, following two related patents are found:

1, a kind of modularization single battery box (CN205900647U), including single battery box body, tab fixed block, survey Drum device, insulation top plate；Single battery core top board and lower platen are fixed in the battery case of single battery box body, and tab is solid Determine the lateral surface of block and the mounting of roof plate fixing end that insulate, cell polar ear is fixed on tab fixed block, is surveyed drum device and is mounted on admittedly The medial surface of fixed end.The box body of the battery case is compact to design, safe and reliable, and not only solving single battery, directly assembly is asked in groups Topic, and safety is improved, the energy density of battery pack is improved, the structural complexity of system is reduced, also adds survey Bulging function further improves the safety of single battery core.

2, a kind of modular battery box (CN205531759U) applied to electronic lock, including battery compartment and box cover, it is described Battery compartment front end is provided with box cover spiral-lock component, and the box cover spiral-lock component includes button, sliding block, is fixedly installed below button One circular cone, the sliding block are slidably arranged in battery compartment front end, and the recess with circular cone cooperation is offered in the middle part of sliding block, described Slider end is provided with a convex block, and the battery compartment rear end offers card hole, the box cover rear end by configure detent block with Card hole cooperation is installed on battery compartment rear end, and the front end of lid is provided with a spiral-lock block, and offering on the spiral-lock block can For the button hole of the convex block insertion of slider end, pushing button can be moved forward by circular cone and recess band movable slider, so that convex block It is detached from button hole, can be opened the lid, unlatching is very convenient, facilitates and carries out the operations such as replacement battery, and can be used as a module It is set to inside electronic lock, avoids the color matching and appearance that influence electrical lock panel.

By the comparison of technical characteristic, above-mentioned two patent document structures are complex, are equipped with driving motor etc., Although being improved in terms of the anti-shock steady of battery, higher cost, and it is not identical as the structure of the present utility model application, It will not influence the novelty and creativeness of the present utility model application.

Utility model content

The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide one kind can easily and fast realize pair The modular battery box of battery case linkage locking, to guarantee the stability and cell safety of battery.

The utility model realizes that the technical solution of purpose is:

A kind of modular battery box of linkage self-locking, including box cover and box body are provided with fixed ring in box body two sides, in box It is provided with the locating slot of battery in vivo, box cover hinge is mounted in the side of box body, it is characterised in that: in the box body that box cover opens side Two locking levels are longitudinally provided with, which is the setting that is coaxial docking, and is oriented to and slides in the made half slot of box body It is dynamic；It is coaxially mounted on a holddown spring on the box body of two locking level two side ends, is spaced and is fixed on two locking levels Multiple vertical latch hooks；Be embedded in and one release the button on the box cover of two locking level docking sites, this release the button with below Box body between be symmetrically installed with reset spring, made led in the lower end surface of releasing the button of corresponding two locking level docking sites A press-fitted block is slidably fitted in slot, glut is made in the lower part of the press-fitted block, which snaps in the docking section of two locking levels Position；Be formed with locked groove on the box cover for the latch hook position that corresponding locking level is fixedly mounted with, the locked groove in two locking level left and right displacements, Latch hook locking or release box cover.

Moreover, being equipped with a protection handle on the box body at position of releasing the button.

The advantages and positive effects of the utility model are as follows:

1, opening of this battery case in box cover side, which is equipped with, releases the button, and link a press-fitted block under the button, leads to Cross the made wedge-shaped wedge angle in the press-fitted block lower part, can the locking level bilateral symmetry to two sides be displaced, thus will be packed in lock Fixed pole radially open or be locked on lid by made lock hook, is achieved in the stable position to battery in battery case, together When also guarantee the safety of battery.

2, this battery case is equipped with a protection handle on the box body at position of releasing the button, and is not only conducive to start button Manual operation, while the maloperation of start button can also be protected.

3, this battery case is mounted on reset spring in locking level two sides and on releasing the button, and sets that release the button be normal The self-locking state closed, when avoiding battery case because of replacement or movement caused by battery fall off problem, it is practical and reliable.
