Description

Technical Field

[0001] This utility model relates to the field of electric vehicle communication technology, specifically a waterproof electric vehicle mutual recognition module. Background Technology

[0002] The electric vehicle mutual recognition module is a key technical component in the intelligent and networked development of electric vehicles. Its core function is to realize safe identity recognition, data interaction and collaborative control between electric vehicles of different brands and models or between electric vehicles and external devices.

[0003] In existing technologies, mutual recognition modules typically adopt an integrated design, with the main structure being a box. Inside the box, a highly integrated identification chip is fixedly installed to store key data such as the vehicle's unique identification information and digital authentication certificate. It also has a built-in high-performance encryption algorithm engine that can encrypt interactive data in real time to ensure the security of the communication process.

[0004] The chip is electrically connected to external devices via multiple flexible wires, which must pass through pre-drilled wire holes at both ends of the housing. However, with prolonged use, material aging and deformation due to temperature cycling gradually create sealing gaps, allowing rainwater to seep into the housing along the wire surfaces. This directly corrodes the chip and surrounding circuitry, leading to serious problems such as communication interruptions, data loss, and even overall module failure, severely limiting the reliability and lifespan of the electric vehicle interoperability module. Therefore, we propose a waterproof electric vehicle interoperability module to effectively address these shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof electric vehicle mutual recognition module to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a waterproof electric vehicle mutual recognition module, including a box body, with a plurality of first wire holes opened on the left and right side walls of the box body, and two partitions fixed vertically inside the box body, the two partitions being symmetrically distributed on the left and right side walls of the box body, with a plurality of second wire holes opened on the partitions, and a waterproof cavity being formed between the partitions and the side walls of the box body, the waterproof cavity being used to prevent rainwater from passing through the second wire holes and entering the interior of the box body.

[0007] Optionally, a plurality of the first wire holes are at the same horizontal height, and a plurality of the second wire holes are at the same horizontal height, wherein the height of the second wire holes is higher than the height of the first wire holes.

[0008] Optionally, a drainage hole is provided at the bottom of the box, and the drainage hole is connected to the waterproof cavity.

[0009] Optionally, the box body includes a lower shell and an upper shell, the upper shell being detachably connected to the top of the lower shell, the lower shell having a U-shaped cross-section, and the upper shell having a U-shaped cross-section.

[0010] Optionally, the partition includes a lower plate and an upper plate, the lower plate being fixedly connected to the bottom wall of the lower housing, and the upper plate being fixedly connected to the top wall of the upper housing, with the lower plate and the upper plate slidingly engaged vertically.

[0011] Optionally, both the first wire hole and the second wire hole are circular through holes with the same diameter. The center of the first wire hole is located at the junction of the lower shell sidewall and the upper shell sidewall, and the center of the second wire hole is located at the junction of the lower plate and the upper plate.

[0012] Optionally, a sealing ring is fixedly provided on the inner wall of both the first wire hole and the second wire hole. The sealing ring is annular and is composed of two semi-circular bodies.

[0013] Compared with the prior art, this utility model provides a waterproof electric vehicle mutual recognition module, which has the following beneficial effects:

[0014] 1. This utility model sets a partition inside the box, which cooperates with the side wall of the box to form a waterproof cavity. Water enters the waterproof cavity after passing through the first wire hole, and the water that enters the waterproof cavity will be discharged through the drainage hole at the bottom. This makes it difficult for rainwater to pass through the second wire hole and enter the box to affect electronic components such as chips, thus extending the service life of the device.

[0015] 2. In this utility model, the second wire hole on the partition plate is at a higher height than the first wire hole. Therefore, the side of the wire closer to the first wire hole is lower, making it difficult for rainwater to flow from bottom to top to the second wire hole, further making it difficult for rainwater to enter the box and improving the waterproof effect.

[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4 A waterproof electric vehicle interoperability module includes a housing 1. The left and right side walls of the housing 1 have several first wire holes 2 for wires to pass through. Two partitions 3 are vertically fixed inside the housing 1, symmetrically distributed near the left and right side walls. Each partition 3 has several second wire holes 4 for wires to pass through. A waterproof cavity 5 is formed between the partitions 3 and the side walls of the housing 1. This waterproof cavity 5 prevents rainwater from passing through the second wire holes 4 and entering the housing 1. Therefore, when rainwater passes through the first wire holes 2, it enters the waterproof cavity 5, making it difficult for rainwater to pass through the second wire holes 4 and affect electronic components such as chips.

[0023] The partition 3 and the inner wall of the box 1 are fixedly connected to each other so that there is no gap between the partition 3 and the box 1, thus preventing rainwater from seeping in.

[0024] Furthermore, several first wire holes 2 are at the same horizontal height, and several second wire holes 4 are at the same horizontal height, with the second wire holes 4 located at a higher height than the first wire holes 2. Therefore, when the wire passes through the first wire holes 2 and the second wire holes 4, the side of the wire closer to the first wire hole 2 is at a lower height than the side closer to the second wire hole 4, making it difficult for rainwater to flow upwards along the wire, and thus making it difficult for rainwater to reach the position of the second wire holes 4, further improving the waterproof effect of the device.

[0025] In order to allow water entering the waterproof cavity 5 to drain out, a drain hole 6 is provided at the bottom of the box body 1 in this application. The drain hole 6 is connected to the waterproof cavity 5 so that water in the waterproof cavity 5 can be discharged to the outside of the box body 1 through the drain hole 6.

[0026] In this embodiment, the box body 1 includes a lower shell 101 and an upper shell 102. The upper shell 102 is detachably connected to the top of the lower shell 101. The lower shell 101 has a U-shaped cross-section, and the upper shell 102 has a U-shaped cross-section.

[0027] like Figure 2 As shown, the inner side wall of the lower housing 101 is provided with a sliding groove for the side wall of the upper housing 102 to slide into. When the upper housing 102 slides into the sliding groove, the upper housing 102 and the sliding groove are sealed together. The facing surfaces of the lower housing 101 and the upper housing 102 are also sealed together to prevent rainwater from seeping in from the connection between the lower housing 101 and the upper housing 102.

[0028] On the other hand, the lower housing 101 and the upper housing 102 can be detachably connected by buckles on the side or by magnetic attraction, ensuring the airtightness of the box 1.

[0029] Furthermore, the partition 3 includes a lower plate 301 and an upper plate 302. The lower plate 301 is fixedly connected to the bottom wall of the lower housing 101, and the upper plate 302 is fixedly connected to the top wall of the upper housing 102. The lower plate 301 and the upper plate 302 slide together vertically.

[0030] The lower plate 301 is fixedly connected to the front and rear side walls of the box 1, and the upper plate 302 slides vertically into the inner side of the lower plate 301. When the upper plate 302 is fully slidably embedded into the inner side of the lower plate 301, the upper plate 302 and the lower plate 301 are sealed together. Furthermore, when the upper shell 102 and the lower shell 101 are connected together, the lower plate 301 and the upper plate 302 are also connected together simultaneously, thereby completing the assembly operation of the box 1.

[0031] It should be noted that both the first wire hole 2 and the second wire hole 4 are circular through holes with equal diameters. The center of the first wire hole 2 is located at the junction of the side wall of the lower housing 101 and the side wall of the upper housing 102, while the center of the second wire hole 4 is located at the junction of the lower plate 301 and the upper plate 302. Therefore, when the lower housing 101 and the upper housing 102, and the lower plate 301 and the upper plate 302 are separated, both the first wire hole 2 and the second wire hole 4 will be divided into two arc-shaped grooves. The upper arc-shaped groove of the first wire hole 2 is located on the side wall of the upper housing 102, and the lower arc-shaped groove is located on the side wall of the lower housing 101. Similarly, the upper arc-shaped groove of the second wire hole 4 is located on the upper plate 302, and the lower arc-shaped groove is located on the lower plate 301.

[0032] Furthermore, a sealing ring 7 is fixedly provided on the inner wall of both the first wire hole 2 and the second wire hole 4. The sealing ring 7 is annular and is composed of two semi-arc bodies.

[0033] The sealing ring 7 is fixed to the hole walls of the first wire hole 2 and the second wire hole 4 by bonding or other connection methods. When the lower housing 101 and the upper housing 102 are combined, the sealing ring 7 in the first wire hole 2 and the second wire hole 4 can squeeze the wire, thereby sealing the sealing ring 7 and the wire, and further preventing rainwater from penetrating into the box 1.

[0034] like Figure 4 As shown, several wires pass through wire holes on the left and right side walls of the housing 1 and extend into the interior of the housing 1 to connect with the electronic chip inside the housing 1. One end of several wires located on the outside of the housing 1 is connected to a CAN bus interface, an RS-485 interface, and other mutual recognition module interfaces to connect with devices or systems using other communication protocols and expand the communication range.

[0035] The working principle and usage process of this utility model are as follows: First, during installation, the wires can be passed through the first wire hole 2 and the second wire hole 4 on the lower housing 101 to connect the wires to the electronic chip inside the box 1. Then, the upper housing 102 is assembled vertically aligned with the top of the lower housing 101, so that the side wall of the upper housing 102 and the side wall of the lower housing 101 are aligned, and the upper plate 302 and the lower plate 301 are aligned. At this time, the sealing rings 7 in the first wire hole 2 and the second wire hole 4 can squeeze and fix the wires to achieve a good sealing effect. After the assembly is completed, rainwater will have difficulty entering the box 1. Even if rainwater enters the box 1, it will first enter the waterproof cavity 5 through the first wire hole 2 and then be discharged by the drainage hole 6 in the waterproof cavity 5. It will be difficult for rainwater to pass through the second wire hole 4 and enter the box 1 to affect the electronic chip and other components.
