A sensor support for a pouch battery module

Abstract

This invention provides a sensor bracket for a pouch battery module, comprising a bracket body, a snap fastener, and a sensor. The bracket body is disposed between the ends of two adjacent pouch batteries. The bracket body has a snap fastener mounting area, in which the snap fastener is mounted. A snap-fit ​​connection mechanism is provided between the snap fastener and the bracket body. An elastic body is disposed on the snap fastener, and the sensor is disposed between the elastic body and the pouch battery. The snap fastener brings the sensor into contact with the outer surface of the pouch battery. This invention uses a snap fastener to mount the sensor. When the snap fastener is pressed into place, the sensor contacts the outer surface of the pouch battery. Due to the presence of the elastic body, it provides elastic support for the sensor. The elastic force applied by the elastic body to the sensor is moderate, ensuring a tight fit between the sensor and the outer surface of the pouch battery while avoiding excessive pressure that could cause the sensor to sink into the pouch battery and damage it.

Description

Technical Field

[0001] This utility model relates to the field of soft-pack battery technology, and in particular to a sensor bracket for soft-pack battery modules. Background Technology

[0002] In related technologies, a pouch battery module typically consists of multiple pouch batteries and multiple brackets. The brackets are placed between two adjacent pouch batteries and are used to connect the electrodes of the two batteries so that the pouch batteries are connected in series. After connection, there will be a certain gap between the two pouch batteries. Temperature sensors (thermometers) are usually placed in this gap to monitor the temperature of the pouch batteries.

[0003] However, fixing the temperature sensor in this way has several problems: if the temperature sensor is not installed properly and is located between two battery cells, and the squeezing force between the adjacent pouch cells is too large, the temperature sensor may easily fall into the pouch cells under pressure, thus affecting the quality of the battery cells; if the squeezing force between the adjacent pouch cells is too small, the temperature sensor will not be able to stick tightly to the pouch cells, resulting in a large deviation in the temperature measurement data and low accuracy of the measurement results. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a sensor bracket for soft-pack battery modules.

[0005] The purpose of this utility model is achieved through the following technical solution: a sensor bracket for a soft-pack battery module, comprising a bracket body, a snap fastener, and a sensor. The bracket body is disposed between the ends of two adjacent soft-pack batteries. The bracket body is provided with a snap fastener mounting area, and the snap fastener is installed in the snap fastener mounting area. A snap fastener connection mechanism is provided between the snap fastener and the bracket body. An elastic body is provided on the snap fastener, and the sensor is disposed between the elastic body and the soft-pack battery. The sensor is brought into contact with the outer surface of the soft-pack battery through the snap fastener.

[0006] Preferably, the snap-fit ​​connection mechanism includes slots on both sides of the snap-fit ​​mounting area and snap-fit ​​bodies on both sides of the snap-fit ​​corresponding to the slots; when the snap-fit ​​is installed in the snap-fit ​​mounting area on the bracket body, the snap-fit ​​bodies snap into the slots.

[0007] Preferably, the elastomer is made of foam.

[0008] Preferably, a potting channel is formed between the snap and the bracket body, and the sensor cable passes through the potting channel.

[0009] Preferably, the support body is provided with a conductive sheet, and the pouch battery is provided with a first tab and a second tab. In two adjacent pouch batteries, the first tab of one pouch battery and the second tab of the other pouch battery are simultaneously connected to the conductive sheet on the support body.

[0010] Preferably, a limiting groove is provided on one side of the snap fastener mounting area, the length direction of the limiting groove is consistent with the pressing direction of the snap fastener, and a protrusion is provided on the snap fastener, which is engaged in the limiting groove; the pressing stroke of the snap fastener is limited by the cooperation between the protrusion and the limiting groove.

[0011] Preferably, the bracket body has two insertion posts on both sides of one end and insertion holes on both sides of the other end.

[0012] The beneficial effects of this utility model are as follows: This utility model achieves sensor installation through a snap button. When the snap button is pressed into place, the sensor contacts the outer surface of the soft-pack battery. Due to the presence of the elastomer, the elastomer can provide elastic support for the sensor. The elastic force applied by the elastomer to the sensor is moderate, which can ensure that the sensor is tightly attached to the outer surface of the soft-pack battery, and can also avoid excessive pressure on the sensor, which would cause the sensor to fall into the soft-pack battery and damage the soft-pack battery.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] like Figures 1 to 3As shown, a sensor bracket for a pouch battery module includes a bracket body 2, a snap fastener 7, and a sensor 17. The bracket body 2 is disposed between the ends of two adjacent pouch batteries 1. The bracket body 2 has a snap fastener 7 mounting area, and the snap fastener 7 is installed in the snap fastener 7 mounting area. A snap fastening connection mechanism is provided between the snap fastener 7 and the bracket body 2. An elastic body 8 is disposed on the snap fastener 7, and the sensor 17 is disposed between the elastic body 8 and the pouch battery 1. The snap fastener 7 makes the sensor 17 contact the outer surface of the pouch battery 1.

[0019] In this invention, the bracket body 2 is connected to the electrodes on two adjacent soft-pack batteries 1. A certain gap is formed between the ends of the two adjacent soft-pack batteries 1 and the bracket body 2. The sensor 17 is installed in this gap, rather than directly in the gap between the two soft-pack batteries 1. When installing the sensor 17, the sensor 17 is mounted on the elastic body 8, and the snap 7 is pressed into the snap 7 mounting area on the bracket body 2. The snap 7 is fixed to the bracket body 2 through the snap connection mechanism. When the snap 7 is pressed into place, the sensor 17 contacts the outer surface of the soft-pack battery 1. Due to the presence of the elastic body 8, the elastic body 8 can provide elastic support for the sensor 17. The elastic force applied by the elastic body 8 to the sensor 17 is moderate, which can ensure that the sensor 17 is in close contact with the outer surface of the soft-pack battery 1, and can also avoid excessive pressure on the sensor 17, which would cause the sensor 17 to fall into the soft-pack battery 1 and damage the soft-pack battery 1.

[0020] The snap-fit ​​connection mechanism includes slots 11 on both sides of the snap 7 mounting area and snap-fit ​​bodies 10 on both sides of the snap 7 and corresponding to the slots 11. When the snap 7 is installed in the snap 7 mounting area on the bracket body 2, the snap-fit ​​body 10 snaps into the slot 11.

[0021] In this embodiment, the elastomer 8 is made of foam.

[0022] Furthermore, a potting channel 12 is formed between the snap fastener 7 and the bracket body 2, through which the cable 9 of the sensor 17 passes. After the sensor 17 is installed in place, glue is injected into the space where the sensor 17 is located through the potting channel 12, thereby further improving the fixing effect of the sensor 17.

[0023] A conductive sheet 3 is provided on the support body 2, and a first tab 5 and a second tab 6 are provided on the pouch battery 1. In two adjacent pouch batteries 1, the first tab 5 of one pouch battery 1 and the second tab 6 of the other pouch battery 1 are simultaneously connected to the conductive sheet 3 on the support body 2. When the pouch batteries 1 are arranged, in two adjacent pouch batteries 1, the first tab 5 of one pouch battery 1 is aligned with the second tab 6 of the other pouch battery 1 (i.e., the two adjacent pouch batteries 1 are arranged in opposite directions), and the first tab 5 and the second tab 6 of the two adjacent pouch batteries 1 are connected through the conductive sheet 3, thereby forming a series connection of the pouch batteries 1.

[0024] To prevent excessive pressure damage to the pouch battery 1 caused by excessive pressing stroke of the snap 7 during sensor 17 installation, a limiting groove is provided on one side of the snap 7 installation area. The length direction of the limiting groove is consistent with the pressing direction of the snap 7. The snap 7 is provided with a protrusion 14, which engages with the limiting groove. The pressing stroke of the snap 7 is limited by the cooperation between the protrusion 14 and the limiting groove. In this utility model, by providing a limiting groove and the cooperation between the protrusion 14 and the limiting groove, the pressing stroke of the snap 7 is limited. When the snap 7 reaches a certain pressing distance, the protrusion 14 on the snap 7 will move to the bottom of the limiting groove, thereby preventing the snap 7 from being pressed further down and thus avoiding damage to the pouch battery 1.

[0025] The bracket body 2 has two insertion posts 15 on both sides of one end and two insertion holes 16 on both sides of the other end. Two adjacent bracket bodies 2 are arranged in opposite directions. When two adjacent bracket bodies 2 are connected, the insertion post 15 on one bracket body 2 is inserted into the insertion hole 16 on the other bracket body 2. Through the cooperation between the insertion post 15 and the insertion hole 16, a stable connection between adjacent bracket bodies 2 is achieved.

[0026] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
