Description

Technical Field

[0001] This utility model belongs to the field of new energy battery module technology, and specifically relates to a data acquisition connector fixing base structure and battery. Background Technology

[0002] As a key application area in the new energy field, the safety performance of electric vehicles has attracted much attention. Battery information collection is a core link to ensure the safe operation of electric vehicles, and its reliability directly affects the overall safety status of the vehicle.

[0003] Especially in special application scenarios such as heavy-duty trucks, vehicles often face extremely harsh operating conditions, including but not limited to severe vibrations, frequent impacts, complex temperature changes, and dusty and humid environments. Under such conditions, the fixed reliability of the connectors used for battery information collection (hereinafter referred to as "collection connectors") is particularly important.

[0004] Currently, the industry's method for fixing data acquisition connectors is relatively simple, generally using a hot-riveting process to directly fix them to the battery tray. However, this fixing method reveals significant drawbacks under the aforementioned harsh operating conditions: the structural strength of the hot-riveted connection is insufficient to withstand continuous vibration and impact, easily causing the data acquisition connector to detach from the tray. Once detached, the data acquisition connector will experience irregular shaking inside the battery pack. This not only causes interruptions or anomalies in battery information acquisition, preventing the vehicle from accurately obtaining battery status parameters (such as voltage, temperature, SOC, etc.), affecting the normal control and operation of the entire vehicle; more seriously, the shaking connector may collide or rub against other components inside the battery pack, even causing short circuits, cell damage, and other problems, posing a significant safety hazard and a serious threat to the safety of the vehicle and its occupants.

[0005] Therefore, there is an urgent need for a more reliable and stable fixing structure or method to address the issue of fixing the data acquisition connectors under harsh working conditions such as heavy-duty trucks. This would overcome the shortcomings of existing hot riveting fixing methods, ensure the accuracy and continuity of battery information acquisition, and eliminate potential safety risks.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] like Figure 1As shown, this is a data acquisition connector fixing base structure, which consists of an FPC component 1, a plug-in assembly 2, a reinforcing assembly 3, a base 4, and an end plate 5. The FPC is a flexible printed circuit board. One end of the FPC component 1 is connected to the plug-in assembly 2 to ensure stable signal transmission. The plug-in assembly 2 is integrated onto the surface of the reinforcing assembly 3 by welding, significantly improving the structural strength of the connection. The reinforcing assembly 3 is detachably connected to the base 4, ensuring connection stability and providing convenient operation space for future maintenance and replacement. The base 4 and end plate 5 also adopt a detachable connection structure, simplifying the overall assembly process and allowing for flexible adjustment of component fitting accuracy according to actual usage requirements.

[0049] like Figure 2 As shown, the reinforcing component 3 is composed of a reinforcing plate 301 and double-sided adhesive 302. A reinforcing plate 301 is adhered to both the upper and lower surfaces of the double-sided adhesive 302, forming a stable laminated structure through the adhesive force, significantly enhancing the overall bending resistance and structural rigidity of the component. Additionally, as... Figure 3 As shown, both ends of the reinforcing plate 301 are provided with notches 303 (optionally rectangular notches). The notches 303 are designed to cooperate with the corresponding structure of the base 4, which can not only realize the quick positioning of the reinforcing component 3 and the base 4, but also further improve the stability after connection through the concave-convex interlocking, effectively avoiding displacement or loosening during assembly. This embodiment does not limit the material and size of the reinforcing plate 301. For example, the material of the reinforcing plate 301 is FR4 with a thickness of 1.5mm.

[0050] like Figure 2 As shown, the FPC component 1 includes a first circuit board 101 and a second circuit board 102, wherein the first circuit board 101 is fixed to the surface of one of the reinforcing plates 301 by a plug-in assembly 2, and the second circuit board 102 is fixed to the surface of the other reinforcing plate 301 by a plug-in assembly 2.

[0051] It should be noted that there is a circuit between the first circuit board 101 and the second circuit board 102, which can transmit the information collected from the battery cell to the port of the connector 2 via pins. The FPC component 1 and the connector 2 are soldered together. Alternatively, the connector 2 can be configured as a female connector, which, after being soldered to the FPC component 1, is then plugged into a male connector for information collection.

[0052] Furthermore, in Figure 2In the process, the plug-in assembly 2 is composed of a first plug-in 201 and a second plug-in 202. The pins of the first plug-in 201 pass through the first circuit board 101 and are soldered to the corresponding reinforcing plate 301 to ensure stable conduction of the signal transmission path. The pins of the second plug-in 202 pass through the second circuit board 102 and are also soldered to the corresponding reinforcing plate 301.

[0053] It should be noted that during assembly, the plug-in component 2 and the FPC component 1 can be placed sequentially on the reinforcing plate 301. The welding operation of the pins of the plug-in component 2 allows the FPC component 1 to rigidly connect with the reinforcing plate 301. This design utilizes the high strength of welding to prevent relative displacement between components and ensures signal communication between the FPC component 1 and the plug-in component 2 through the conductivity of the pins. Furthermore, when the reinforcing component 3 is placed into the base 4, the notch 303 on its side will engage with the corresponding structure on the base 4, thereby fixing the reinforcing component 3 in place. The FPC component 1 and the plug-in component 2 integrated on the reinforcing component 3 are also indirectly fixed to the base 4 in this way.

[0054] like Figure 4 As shown, the base 4 can adopt a U-shaped structure design, with a stepped structure 407 symmetrically arranged on its top. This stepped structure 407 can cooperate with the end of the reinforcing plate 301, specifically:

[0055] The vertical section of the stepped structure 407 is fitted with an elastic locking block 403, which engages with the notches 303 at both ends of the reinforcing plate 301, achieving initial fixation of the reinforcing component 3 through elastic locking. To further constrain the position of the reinforcing component 3, an upper stop block 402 is provided at the top of the vertical section of the stepped structure 407, which effectively limits the displacement of the reinforcing component 3 in the vertical direction, preventing up-and-down wobbling after assembly. In this embodiment, there is no specific limitation on how the locking block 403 is detachably assembled with the notch 303. For example, the vertical section of the stepped structure 407 is also provided with an auxiliary hole 405, in which the locking block 403 is placed. This design provides installation space for the locking block 403 and enhances the stability of the elastic deformation of the locking block 403 through the support of the hole wall, extending its service life.

[0056] From the perspective of ease of assembly, the base 4 has a guide opening 401 at the front end of the stepped structure 407. This opening not only provides guidance for the insertion of the reinforcing component 3, but also serves as a pick-and-place opening for later maintenance, greatly improving the efficiency of loading and unloading. The rear end of the stepped structure 407 is provided with a front stop 404, which cooperates with the locking block 403 to restrict the degree of freedom of the reinforcing component 3 in the insertion / removal direction, ensuring that the component will not be displaced by external force during operation.

[0057] Combination Figure 5It is known that the surface of the base 4 facing the end plate 5 is provided with a buckle 406, and correspondingly, the surface of the end plate 5 facing the base 4 is provided with a through hole. During assembly, the buckle 406 can be inserted into the through hole to achieve a detachable connection between the two. To optimize the locking performance of the buckle 406, the buckle 406 is designed as a columnar structure, with an opening gap 4061 (generally 2mm) at its end along the axial direction, dividing the buckle 406 into two symmetrical semi-cylinders; at the same time, a barb 4062 is also provided at the end with the opening gap 4061. When the buckle 406 is inserted into the through hole, the two semi-cylinders will elastically contract due to the opening gap 4061, reducing the diameter of the column, so as to smoothly pass into the through hole of the end plate 5. The barb 4062 forms a mechanical limit with the edge of the through hole after being fully engaged, ensuring the firmness of the connection. This embodiment does not limit the material of the end plate 5. For example, the end plate 5 can be made of ADC12 material.

[0058] It should be noted that the bottom of the base 4 can be a hollow structure, and the buckle 406 can be installed on the inner surface of the hollow structure, so that the buckle 406 protrudes from the base 4. In addition, the opening gap 4061 does not extend through the entire buckle 406; its main purpose is to ensure that the end inserted into the through hole can retract to facilitate insertion into the through hole. Furthermore, the barb 4062 can be provided on one of the semi-cylinders, and the barb 4062 is provided with a chamfer.

[0059] like Figure 6 The image shows a battery that integrates multiple of the aforementioned data acquisition connector mounting base structures, located at... Figure 6 In area A, the battery cell is connected to the end of the FPC component 1 away from the connector 2, so that information collected from the cell can be transmitted to the connector 2 via pins.
