Description

Technical Field

[0001] This utility model belongs to the field of lithium battery technology and relates to a quick-connect and swappable lithium battery. Background Technology

[0002] Quick-release lithium batteries are widely used in electric vehicles (two-wheeled or three-wheeled). They are quickly assembled and positioned by guide strips on the inner wall of the battery cavity and slots on the battery casing. Most existing technologies use this type of structure. However, due to frequent bumps during riding, the installation gaps in the lithium battery due to the snap-fit ​​method can cause the lithium battery to move around, which can lead to a certain risk of damage and affect the reliability of the power connection. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a quick-installation and battery swapping lithium battery. The technical problem this invention aims to solve is how to improve the reliability of lithium batteries after installation.

[0004] The objective of this utility model can be achieved through the following technical solution: A quick-installation and swapping lithium battery, characterized in that it includes a housing and a locking plate. A slot is respectively opened on two straight sides facing each other on the housing. A clearance groove penetrating the bottom surface of the housing is opened at the bottom of the slot. The locking plate includes a force-bearing part parallel to the bottom surface of the housing and two elastic parts located on both sides of the force-bearing part. The elastic parts are elastic corrugated and located in the corresponding clearance grooves. In the natural state, the two ends of the force-bearing part are located below the bottom surface of the housing.

[0005] Furthermore, the middle part of the force-bearing part is fixedly connected to the bottom surface of the housing by screws.

[0006] Furthermore, the locking plate is made of plastic.

[0007] During the installation of the lithium battery, the battery casing is placed in the battery housing cavity by the matching slot with the corresponding locking strip on the vehicle body and sliding vertically in. Before sliding into the bottom of the battery housing cavity, there is no contact between the two sides of the force-bearing part and the bottom of the battery housing cavity, and the corrugated elastic part is in a natural state, without obstructing the fit between the slot and the locking strip. When the lithium battery casing is about to reach the limit position of the installation, the two ends of the force-bearing part are squeezed between the bottom of the battery housing cavity, causing the elastic part to deform under pressure. The corrugated elastic part contracts, and the overall thickness increases. This forms a gap between the bottom of the slot and the locking strip on the vehicle body, which helps to eliminate the assembly gap, making the lithium battery casing more secure, the assembly position more reliable, eliminating shaking, and improving the safety and reliability of the lithium battery in the assembly state.

[0011] In the diagram, 1 is the housing; 2 is the slot; 3 is the clearance groove; 4 is the force-bearing part; and 5 is the elastic part. Detailed Implementation

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 and Figure 3 The quick-connect lithium battery shown includes a housing 1 and a locking plate. A slot 2 is provided on each of the two flat sides facing each other on the housing 1. A clearance groove 3 penetrating the bottom surface of the housing 1 is provided at the bottom of the slot 2. The locking plate includes a force-bearing part 4 parallel to the bottom surface of the housing 1 and two elastic parts 5 located on both sides of the force-bearing part 4. The elastic parts 5 are elastic corrugated and located in the corresponding clearance groove 3. In the natural state, the two ends of the force-bearing part 4 are located below the bottom surface of the housing 1.

[0014] The middle part of the force-bearing part 4 is fixedly connected to the bottom surface of the housing 1 by screws, and the locking plate is made of plastic.

[0015] When the lithium battery is installed, the slot 2 engages with the corresponding locking strip on the vehicle body, allowing the lithium battery casing 1 to slide vertically into the battery housing cavity. Before sliding into the bottom of the battery housing cavity, there is no contact between the two sides of the force-bearing part 4 and the bottom of the battery housing cavity, and the corrugated elastic part 5 is in its natural state, not hindering the engagement between the slot 2 and the locking strip. When the lithium battery casing 1 is about to reach the installation limit position, the two ends of the force-bearing part 4 are squeezed against the bottom of the battery housing cavity, causing the elastic part 5 to deform under pressure. The corrugated elastic part 5 contracts, increasing its overall thickness, which forms a gap between the bottom of the slot 2 and the locking strip on the vehicle body, thus eliminating the assembly gap, making the lithium battery casing 1 secure, the assembly position more reliable, eliminating shaking, and improving the safety and reliability of the lithium battery in the assembly state.

[0016] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
