Description

Technical Field

[0001] This utility model relates to the field of battery technology, and more specifically, to a battery stop bracket assembly. Background Technology

[0002] Lithium batteries require real-time monitoring of their status during operation in order to respond promptly and improve battery safety.

[0003] Existing technologies typically monitor battery status using sensors, such as real-time monitoring of critical parameters like internal temperature, pressure, and voltage of lithium-ion batteries. However, some existing technologies involve mounting sensor connectors directly to explosion-proof valves, which compromises the valve's safety. Others indirectly characterize internal temperature by attaching temperature-sensing wires to the outside of the cell, but this method cannot directly and accurately monitor internal battery parameters, and the sensor's internal mounting is not secure. Utility Model Content

[0004] This utility model provides a battery stop bracket assembly. In this solution, on the one hand, the sensor is installed inside the battery, which can directly monitor the internal parameters of the battery; on the other hand, the sensor is fixed in place.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A battery stop bracket assembly includes a stop bracket, a pressure plate assembly, and a sensor mounted inside the stop bracket;

[0007] The sensor includes a monitoring unit and a triggering unit connected together; a pressure plate assembly is provided on the outside of the sensor, the pressure plate assembly includes a first pressure plate and a second pressure plate; the first pressure plate is located on the monitoring unit, and the second pressure plate is located on the triggering unit.

[0008] In this design, the sensor is installed inside the battery. The monitoring unit is used to monitor important parameters such as internal temperature, pressure, and voltage of the lithium-ion battery in real time, while the triggering unit can activate the sensor when needed. A pressure plate assembly is used to fix and protect the sensor, improving its installation stability and providing additional protection.

[0009] As a further improvement, the monitoring unit and the triggering unit are connected by a connecting pin line, so that the triggering unit can activate the monitoring unit for real-time monitoring.

[0010] As a further improvement, a first pin line is also connected to the monitoring unit, and a second pin line is also connected to the trigger unit. After the stop bracket assembly is assembled with the battery, the first and second pin lines are respectively connected to the positive and negative terminals of the battery. On the one hand, the battery itself powers the operation of the sensor, and on the other hand, it can monitor the battery's current and voltage in real time.

[0011] As a further improvement, the stop bracket is also provided with a monitoring unit mounting position and a pin mounting position. The monitoring unit is mounted on the monitoring unit mounting position, and the connecting pin is mounted along the pin mounting position. This provides a corresponding setting position for sensor installation.

[0012] As a further improvement, the pin mounting position is located at the vent hole on the stop bracket.

[0013] As a further improvement, the monitoring unit and the trigger unit are located on both sides of the air vent on the stop frame. This allows sufficient space inside the stop frame for the installation of the monitoring unit and the trigger unit.

[0014] As a further improvement, an injection hole is provided on the stop frame, and a raised step is provided on the inner side of the injection hole; when the sensor is installed on the stop frame, the trigger surface of the trigger part faces the raised step. The raised step can strengthen the structural strength around the injection hole, and the trigger surface of the trigger part faces the raised step, with the sealing pin passing through the injection hole and pressing against the trigger surface of the trigger part.

[0015] Other technical problems that the battery stop bracket assembly of this utility model can solve, other technical features contained in the technical solution, and the advantages brought by these technical features will be further explained in detail with reference to the accompanying drawings.

[0026] Combination Figure 1-4 As shown, this embodiment provides a battery stop bracket assembly, including a stop bracket 1, a pressure plate assembly 3, and a sensor installed inside the stop bracket; the sensor includes a monitoring part 41 and a trigger part 43 connected to each other; the pressure plate assembly 3 is disposed outside the sensor, and the pressure plate assembly 3 includes a first pressure plate 31 and a second pressure plate 33; the first pressure plate 31 is located on the monitoring part 41, and the second pressure plate 33 is located on the trigger part 43.

[0027] It should be noted that the stop bracket 1 is applied to lithium batteries. The side of the stop bracket 1 closest to the battery core is the inner side of the stop bracket 1, and the other side opposite to the inner side is the outer side of the stop bracket 1.

[0028] An electrolyte injection hole 10 is provided on the stop bracket 1 for adding electrolyte into the battery through the electrolyte injection hole 10. Furthermore, a raised step 13 is provided on the inner side of the electrolyte injection hole 10 to improve the strength of the structure around the electrolyte injection hole 10.

[0029] The sensor includes a monitoring unit 41 and a trigger unit 43 connected together. When the sensor is mounted on the stop bracket 1, the trigger surface of the trigger unit 43 faces the raised step 13, so that the trigger surface of the trigger unit 43 faces the outside of the injection hole 10. The monitoring unit 41 of the sensor is used to monitor important parameters such as internal temperature, pressure, and voltage of the lithium-ion battery in real time, and the trigger unit 43 of the sensor is used to turn on the sensor.

[0030] In this application, the stop bracket assembly, firstly, is an independent component, and the stop bracket 1 facilitates the placement of sensor mounting positions. Furthermore, the stop bracket 1 is located closest to the battery core, and the sensor, mounted inside the stop bracket, can directly monitor the internal operating status of the battery.

[0031] See Figure 3 As shown, the sensor includes a monitoring unit 41 and a trigger unit 43, which activates the sensor. During battery assembly, the stop bracket assembly formed by the stop bracket 1 and the sensor is installed first, but the battery is not yet running and the sensor does not need to be activated for monitoring. Only after the battery assembly is complete and electrolyte is injected, and a sealing pin 2 is installed on the injection hole 10, is the battery encapsulated. Because the trigger surface of the trigger unit 43 faces the raised step 13, the trigger surface of the trigger unit 43 faces the outside of the injection hole 10. After the sealing pin 2 is installed on the injection hole 10, the sealing pin 2 passes through the injection hole 10 and presses against the trigger surface of the trigger unit 43. Once the trigger unit 43 is triggered by this pressure, the sensor is activated, and the monitoring unit 41 begins monitoring the battery operation.

[0032] See Figure 2 As shown, the monitoring unit 41 and the trigger unit 43 are connected via a connecting pin line 42. A first pin line 44 is also connected to the monitoring unit 41, and a second pin line 45 is connected to the trigger unit 43. After the stop bracket assembly is assembled with the battery, the first pin line 44 and the second pin line 45 are respectively connected to the positive and negative terminals of the battery. This allows the battery itself to power the sensor and simultaneously monitor the battery's current and voltage in real time. It should be noted that the sensor in this application is a wireless sensor, installed inside the battery, and its monitored data is transmitted wirelessly in real time.

[0033] See Figure 4As shown, the stop frame 1 is also provided with a monitoring unit mounting position 11 and a pin line mounting position 12. The monitoring unit 41 is mounted on the monitoring unit mounting position 11, and the connecting pin line 42 is mounted along the pin line mounting position 12. During installation, it can be fixed by components such as clips.

[0034] See Figure 1 and Figure 2 As shown, the pin mounting position 12 is located at the vent on the stop frame 1. The position of the vent on the stop frame 1 corresponds to the position of the battery's explosion-proof valve, and a fence structure is provided at the vent on the stop frame 1. The pin mounting position 12 is located on the fence structure to avoid affecting the venting of the vent on the stop frame 1.

[0035] Furthermore, the monitoring unit 41 and the trigger unit 43 are located on both sides of the air vent on the stop frame 1. This ensures that there is sufficient space inside the stop frame 1 for the installation of the monitoring unit 41 and the trigger unit 43.

[0036] In this design, the sensor is located inside the stop bracket 1, within the battery. To further protect the sensor, a pressure plate assembly 3 is installed on its outer side. A first pressure plate 31 is located on the monitoring section 41 to protect it, and a second pressure plate 33 is located on the trigger section 43 to protect it. Furthermore, the pressure plate assembly 3 also includes a central pressure plate 32, located on the connecting pin wire 42. The central pressure plate 32 provides positioning and protection for the connecting pin wire 42, and also insulates the connecting pin wire 42 from the battery core. By using the pressure plate assembly 3 to fix and protect the sensor, the sensor's installation stability is improved, and the pressure plate assembly 3 also provides protection for the sensor.

[0037] The pressure plate assembly 3 is fixedly connected to the inner side of the stop frame 1. Specifically, the stop frame 1 is provided with a pair of positioning buckles 14. When the components in the pressure plate assembly 3 are connected to the stop frame, they are fixed between the pair of positioning buckles 14. The pin wire mounting position 12 is in the shape of a slot, which can install and connect the pin wire 42, and the central pressure plate 32 is engaged in the slot of the pin wire mounting position 12.

[0038] The terms “installation,” “setup,” “equipped with,” and “connection” used herein should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0039] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
