Description

Technical Field

[0001] This utility model relates to the field of automotive batteries, specifically a fixed automotive start-stop battery. Background Technology

[0002] Automotive start-stop batteries are commonly used automotive electrical components, and most current start-stop batteries use a lead-acid battery structure. With the rise of new energy batteries, lithium batteries or sodium-lithium batteries are also gradually being used in start-stop battery production. Chinese patent documents CN1835275A and CN215834669U respectively describe the assembly methods of square and round lithium batteries in battery casings, while Chinese patent documents CN210443607U and CN207977430U disclose the installation structures of lithium batteries in battery casings. However, in the above-mentioned lithium battery installation structures, since the battery body is fixed to the bottom surface of the battery cover via terminals, there are no positioning or fixing components for the battery body within the battery casing. In reality, driving or engine operation will cause the battery to vibrate to a certain extent. This vibration will cause the battery body to shake continuously within the battery casing, and may loosen the fixing structure between the battery body and the battery cover, seriously affecting the normal use of the start-stop battery and, in severe cases, shortening the battery's lifespan. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an easy-to-install, stable and reliable internally fixed automotive start-stop battery.

[0004] This utility model provides an internally fixed automotive start-stop battery, mainly comprising a top cover, a housing, and a battery body. The top cover and housing are fixed together in a top-to-bottom arrangement, while the battery body is disposed inside the housing and electrically connected to the outside via the top cover. The top cover also has a clamping part that extends into the housing and connects to the battery body, fixing the battery body within the housing. The housing also has a fixing part, positioned corresponding to the clamping part, and equipped with fixing ribs that press against the clamping part, completely securing the battery body within the housing.

[0005] By optimizing the above structure, four fixing parts are set inside the housing and evenly distributed at the four corners of the housing cavity. Convection cavities are provided between the fixing parts to facilitate heat dissipation from the battery body.

[0006] By optimizing the above structure, the fixing ribs are arranged along the direction in which the clamping part is inserted into the housing, and they are evenly distributed and arranged on the outer surface of the fixing part. The ends of the fixing ribs have guide platforms, which are located at the ends of the fixing ribs near the opening of the housing, to facilitate the clamping part entering the housing.

[0007] By optimizing the above structure, the clamping part includes a fixing plate and a clamping plate. The fixing plate is fixedly connected to the bottom of the top cover, while the clamping plate is located below the fixing plate and corresponds to the position of the battery body.

[0008] By further improving the above structure, a fixing hole is opened on the side of the battery body, and a clamping rib and a connecting hole are provided on the side of the clamping plate that contacts the battery body. The connecting hole corresponds to the fixing hole, and the clamping plate and the battery body are connected together by a connecting pin.

[0009] By further improving the above structure, the clamping plate also has wiring holes. The wiring holes correspond to the positions of the battery body terminals to ensure smooth electrical connection between the battery body and the outside world.

[0010] By optimizing the above structure, the bottom of the casing also has supporting ribs. These ribs support the battery body, increasing the friction between the battery body and the casing, and providing heat dissipation space at the bottom of the battery body.

[0011] The beneficial effects of this utility model of an internally fixed automotive start-stop battery are as follows:

[0012] 1. The start-stop battery of this utility model uses a fixing part inside the casing to connect the battery body within the casing, thereby fixing the battery body between the top cover and the casing. Firstly, this structure allows the battery body to form a fixed whole with the top cover and casing through the fixing part, preventing the battery body from shaking within the casing due to its weight. Secondly, the pressing action of the fixing part on the battery body improves the positional stability between the battery body and the top cover, preventing the battery body from shifting due to vibration and causing loosening of its electrical connection to the outside world, thus improving the stability and reliability of the battery body during operation.

[0013] 2. In the start-stop battery of this utility model, the fixing part is provided with fixing ribs, and there is a convection cavity between the fixing parts, while the bottom of the shell is also provided with supporting ribs. This structure can prevent the inner sidewall of the shell from being tightly attached to the battery body, which is conducive to the heat dissipation of the battery body during operation. In addition, the fixing ribs and supporting ribs can increase the friction between the shell and the battery body, further improving the stability of the connection between the battery body and the shell.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The following embodiments are one or more examples of the new technical solutions of the present utility model, which can achieve the corresponding technical effects and solve the corresponding technical problems, and do not mean that the protection scope of the technical solution only includes the following embodiments.

[0023] according to Figures 1 to 7 As shown, the internally fixed automotive start-stop battery of this utility model mainly includes an upper cover 1, a housing 2, and a battery body 3. The upper cover 1 and the housing 2 are arranged from top to bottom and fixed together. The battery body 3 is located inside the housing 2 and is electrically connected to the outside through the upper cover 1. A clamping part is also provided on the upper cover 1, which is located at the bottom of the upper cover 1 and extends into the housing 2. The clamping part corresponds to the position of the battery body 3 inside the housing 2 and plays a role in clamping and fixing the battery body 3. A fixing part 4 is provided inside the housing 2, which corresponds to the position of the clamping part. The fixing part 4 also has a fixing rib 41, which can press against the clamping part. In this utility model, the fixing part 4, the fixing rib 41, and the housing 2 are manufactured by integral molding. Under the premise of ensuring the working strength of the fixing part 4, it can adopt a hollow cavity structure, that is, there is a cavity 43 between the fixing part 4 and the housing 2. In addition to reducing the weight and manufacturing cost of the housing 2, the cavity 43 also provides a flexible clamping force for fixing the battery body 3. When the fixing part 4 is subjected to the shaking pressure of the battery body 3 during use, it will produce a slight inward deformation in the direction of the housing 2, so as to avoid vibration of the battery body 3 during use due to rigid connection and improve its stability during use. The battery body 3 of this utility model can be either a circular battery pack or a sheet-shaped battery pack.

[0024] In one embodiment of this utility model, four fixing parts 4 are provided inside the housing 2, and are evenly distributed at the four corners of the inner cavity of the housing 2. The fixing parts 4 are located at the four corners of the housing 2, which fully utilizes the structural strength of the corners of the housing 2 to improve the contact strength between the fixing parts 4 and the battery body 3. The even distribution of the fixing parts 4 allows for the application of uniform top pressure on the outer surface of the battery body 3, thereby improving the positional stability of the battery body 3 within the housing 2. A convection cavity 21 is also provided between the fixing parts 4, i.e., the convection cavity 21 is located between adjacent fixing parts 4, so as to leave sufficient heat dissipation space on the outside of the battery body 3 after assembly, improving the safety of the battery body 3 during operation.

[0025] In one embodiment of this utility model, the fixing rib 41 is arranged along the direction in which the clamping part is inserted into the housing 2. This arrangement improves the smoothness of the clamping part entering the housing 2 and prevents jamming between the clamping part and the housing 2 during installation. The fixing rib 41 is evenly distributed on the outer surface of the fixing part 4 to apply a stable top pressure to the outside of the clamping part, making the clamping action of the clamping part on the battery body 3 more stable. The end of the fixing rib 41 also has a guide platform 42, which is located at the end of the fixing rib 41 near the opening of the housing 2. This guide platform 42 is integrally machined onto the fixing rib 41 and serves to guide the clamping part into the housing 2.

[0026] In one embodiment of this utility model, the clamping part includes a fixing plate 51 and a clamping plate 52. The fixing part 4 is located at the bottom of the upper cover 1 and is fixed together with the upper cover 1. The clamping plate 52 extends into the housing 2 and corresponds to the position of the battery body 3. In this embodiment, the fixing plate 51 and the clamping plate 52 are also integrally formed to improve the connection strength between the clamping part and the upper cover 1 and the battery body 3.

[0027] In another embodiment, a fixing hole 31 is formed on the side of the battery body 3, while a connecting hole 54 is formed on the clamping plate 52. The connecting hole 54 is located on the side that contacts the battery body 3 and corresponds to the position of the fixing hole 31. A connecting pin 6 is also provided between the clamping plate 52 and the battery body 3, and the connecting pin 6 can pass through the connecting hole 54 and the fixing hole 31. The fixing hole 31 and the connecting hole 54 are respectively located at the lower part of the battery body 3 and the clamping plate 52. In addition to connecting the clamping plate 52 and the battery body 3, the connecting pin 6 can also form a support structure between the battery body 3 and the clamping plate 52 to improve the positional stability of the battery body 3 within the housing 2. The side of the clamping plate 52 also has a clamping rib 53, which is located on the same side as the connecting hole 54 and is integrally formed with the clamping plate 52 to increase the friction between the clamping plate 52 and the battery body 3 and improve the clamping effect of the clamping plate 52 on the battery body 3.

[0028] In another embodiment, the clamping plate 52 has a wiring hole 55. The wiring hole 55 corresponds to the position of the wiring terminal of the battery body 3, so as to facilitate the electrical connection between the battery body 3 and the outside world.

[0029] In one embodiment of this utility model, the bottom of the housing 2 also has a supporting rib 7. The supporting rib 7 is evenly distributed at the bottom of the housing 2 and protrudes from the inner bottom surface of the housing 2, serving to support the bottom of the battery body 3. In this embodiment, the supporting rib 7 and the housing 2 can be integrally formed, or they can be integrally formed with the fixing rib 41 to reduce processing costs.

[0030] The above specific embodiments are only implementation methods with better technical effects of this utility model. Any structure that is the same as or equivalent to the internal fixed automotive start-stop battery of this utility model is within the protection scope of this utility model.
