Description
Technical Field
[0001] The utility model belongs to the technical field of packaging tools, and in particular relates to a power battery pressing device. Background Art
[0002] With the support of national policies for the new energy vehicle industry, the development of new energy vehicles has achieved unprecedented development. The automotive power battery pack, also known as the power battery module or power battery pack, is the core component of new energy vehicles (such as electric vehicles and hybrid vehicles). Its main function is to store and provide the electrical energy required by the vehicle to ensure the normal operation of the vehicle;
[0003] During transportation, specific packaging carriers and quick clamping self-locking devices are required to ensure the safety of the battery pack. The quick clamping self-locking device plays a vital role in the entire transportation safety process of the power battery pack. Currently, the packaging carriers used for power battery packs are very different. Traditional clamps are often used, but they have the following shortcomings: the clamps require a large space, the clamping locking force is relatively small, and the operation is difficult, which increases the transportation cost and safety hazards to a certain extent;
[0004] In order to solve the above problems, a power battery pressing device is proposed in the present application. Utility Model Content
[0005] The purpose of the utility model is to provide a power battery pressing device to solve the problems raised in the above-mentioned background technology.
[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model is a power battery pressing device, comprising a bottom plate and also comprising:
[0008] The locking sleeve is fixed to the upper end of the bottom plate. The inner cavity of the locking sleeve can stably support the locking column and limit its vertical movement. The upper end of the locking sleeve can position the locking column, the clamping piece, and the locking screw to ensure stability after clamping;
[0009] The pipe sleeve is fixed on the top of the outer side of the locking sleeve, and the pipe sleeve forms a barrier at the upper end of the outer side of the locking sleeve to prevent the locking screw from shaking outward after being inserted, thereby improving the clamping stability of the clamping piece;
[0010] A lock cylinder, which is rotatably arranged inside the lock sleeve and can also slide vertically inside the lock sleeve. In order to facilitate the adjustment of the angle of the pressing member, the lock cylinder can slide vertically and stably inside the lock sleeve and can also rotate;
[0011] A pressing piece, which is fixed to the upper end of the lock column and consists of a rotating plate and a pressing plate. The rotating plate is connected to the lock column and the locking screw, and the pressing plate acts on the battery;
[0012] A locking screw, wherein the locking screw is fixed on the pressing piece and is engaged with the top of the locking sleeve to limit the rotation of the locking column and the pressing piece to achieve circumferential locking;
[0013] A shell, wherein the shell is fixed on the bottom plate, and one side of the shell is in contact with the lock sleeve and the pipe sleeve, and the shell is fixed to the bottom plate by bolts;
[0014] A locking plate, which is inserted between the housing and the lock sleeve and slides horizontally. The locking plate can lock the vertical movement of the lock column with the lock sleeve, thereby providing a stable pressing force;
[0015] A sealing plate is located at one side of the shell and can seal the locking column and the locking plate at the same time.
[0016] Furthermore, the lock sleeve is provided with a square groove for inserting the front end of the locking plate, and the upper end of the lock sleeve is provided with a plurality of countersunk holes distributed in a circumference. A reset spring is arranged between the lock column and the base plate, and the locking screw is automatically disengaged from the countersunk hole through the reset spring. In this scheme, the square groove is used to support the horizontal sliding of the locking plate, and also limits the movable direction of the locking plate. After the locking plate passes through the square groove and is inserted into the lock column, the vertical direction of the lock column can be reliably locked, thereby ensuring the clamping effect of the clamping piece. The plurality of countersunk holes can lock the clamping piece in multiple directions, which is more flexible to use.
[0017] Furthermore, the lock column is provided with a limiting groove for the movement of the front end of the locking plate, and the upper end of the lock column with the limiting groove is also provided with a locking groove, and the front end of the locking plate can be inserted into the locking groove and move in the limiting groove. In this scheme, the limiting groove and the locking groove are both provided in a ring shape. When the front section of the locking plate is engaged with it, it will not affect the rotation of the lock column inside the lock sleeve, thereby facilitating the direction adjustment of the clamping part, and has high flexibility. At the same time, the limiting groove can also play a limiting role in the lock column after the lock column and the lock sleeve are assembled. The limiting groove limits the vertical movement range of the lock column, avoids the lock column from detaching from the top of the lock sleeve after assembly, and achieves a linkage locking effect.
[0018] Furthermore, a first step and a second step are sequentially formed on one side of the locking plate away from the locking column, and an assembly hole for the locking plate to pass through is opened in the shell. In this solution, the locking plate can completely pass through the shell through the assembly hole, which facilitates assembly and subsequent maintenance work, and then the stability of the locking plate is guaranteed under the action of the sealing plate.
[0019] Furthermore, a self-locking spring is arranged between the first step and the inner side of the sealing plate, the front end of the locking plate is inserted into the locking groove through the self-locking spring, and a pull ring is arranged at the rear end of the locking plate. In this scheme, the self-locking spring is fitted on the first step from one end of the locking plate, and then limited by the sealing plate at the fitted end, which can facilitate the assembly and subsequent maintenance of the self-locking spring, and has a simple structure and is easy to form.
[0020] Furthermore, the sealing plate is provided with an active hole for the locking plate to set the second step part to move, and a distance for limiting the movement of the front end of the locking plate between the limiting groove and the locking groove is formed between the second step and the sealing plate. In this solution, the active hole is limited to the movement of the second step position, which provides space for the locking plate to move while limiting the range of movement, thereby facilitating the reliable use of the locking plate.
[0021] Furthermore, the inner side of the tube sleeve blocks the outer side of the countersunk hole of the locking sleeve, and the outer upper end of the lock column blocks the inner side of the countersunk hole of the locking sleeve. The matching parts of the locking sleeve, tube sleeve and lock column in this solution can facilitate the opening of the countersunk hole and ensure the reliability of the locking screw after insertion.
[0022] Furthermore, the locking plate is a flat rectangular shape, the first step and the second step are integrally formed on the side of the locking plate, the upper and lower surfaces of the locking plate are flat, and the front end of the locking plate is provided with an arc groove that matches the locking groove. The shape of the locking plate in this solution is simple, and there is no complicated processing procedure, which reduces the processing difficulty and cost.
[0023] Furthermore, the clamping piece is fixed above the locking column by bolts, and the locking column and the clamping piece are distributed vertically, the locking screw is fixed to the clamping piece by bolts, and the locking screw passes through the lower end of the clamping piece. In this solution, a screw is fixed to the upper end of the locking column, and the clamping piece is fixed to the upper end of the locking column by the screw and the bolt. A through hole for the locking screw to pass through is provided in the clamping piece, and the locking screw is fixed to the clamping piece by bolts. The height and depth of the locking screw of the clamping piece can be adjusted by bolts to adapt to the clamping of battery packs of different heights, and it has higher flexibility.
[0024] The utility model has the following beneficial effects:
[0025] The utility model provides a locking column in a vertical direction, then a limiting groove is provided on the locking column, and then a locking plate in a horizontal direction is inserted into the limiting groove, so the utility model has the advantages of simple structure, strong pressing force and convenient operation.
[0026] The utility model can complete the locking after the overall assembly only by fixing the sealing plate with the shell through the bolts on the sealing plate, and all the components of the device can be easily disassembled, which is convenient for later maintenance and replacement.
[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
