Problems solved by technology

Among them, the size of the path identification card is uniformly stipulated by the expressway management department. Its total thickness cannot be greater than 5mm, and the casing must meet the waterproof and dustproof requirements. Since the thickness of the battery is a standard thickness, generally about 3.6mm, the path identification card The thickness of the shell cannot be thickened
[0004] Due to the thinner shell thickness of the path identification card in the prior art, during the daily storage process of the path identification card, that is, in daily use, if the temperature inside the car is high, the shell of the path identification card will be convex and bulging. , and due to the thin shell, the bulge change is irreversible
If the shell is bulged and deformed, the route identification card cannot be removed from the route identification card storage device, which will lead to traffic jams at high-speed toll stations and accidents such as traffic accidents

Embodiment 1

[0057] figure 1 It is a schematic diagram of the three-dimensional structure of the path identification card provided by Embodiment 1 of the present invention. figure 2 It is a side structural view of the path identification card provided by Embodiment 1 of the present invention. image 3 It is a side sectional view of the path identification card provided by Embodiment 1 of the present invention. refer to Figure 1 to Figure 3 As shown, this embodiment provides a path identification card.

[0058] The path identification card specifically includes: a casing 1 , a circuit board 3 and a battery 4 , the circuit board 3 and the battery 4 are arranged in the inner cavity of the casing 1 , and the circuit board 3 and the battery 4 are electrically connected. The electronic components in the path identification card are powered by the battery 4 . Wherein, the circuit board 3 may specifically be a printed circuit board (Printed Circuit Board, PCB for short).

[0059] In this em...

Embodiment 2

[0089] Figure 4 It is a top structural view of the path identification card provided by Embodiment 2 of the present invention. refer to Figure 4 As shown, this embodiment provides a path identification card with another structure.

[0090] The difference between the path identification card in this embodiment and the path identification card provided in Embodiment 1 lies in that the location of the through hole 10 is different. In this embodiment, the through hole 10 is specifically opened on the main body surface of the housing 1 . This makes opening of the through hole 10 more convenient.

[0091] Specifically, the through hole 10 is opened on the main body surface 110 of the upper shell 11 and / or the main body surface 120 of the lower shell 12 . That is to say, the through hole 10 can be provided on the main body surface 110 of the upper case 11, or the through hole 10 can be provided on the main body surface 120 of the lower case 12, or, between the main body surface...

Embodiment 3

[0097] This embodiment provides a method for making a path identification card, which is used to make the path identification card provided in Embodiment 1 or Embodiment 2. Wherein, the path identification card includes: a casing 1 , a circuit board 3 and a battery 4 , and the circuit board 3 and the battery 4 are arranged in the casing 1 .

[0098] The method specifically includes:

[0099] Step 1: Apply a sealant 2 on the through hole 10 of the casing 1 at a preset ambient temperature. Wherein, the preset ambient temperature is higher than the storage temperature of the path identification card.

[0100] Step 2: Curing the sealant 2 at the preset ambient temperature, so that the cured sealant 2 can seal the through hole 10 .

[0101] It can be understood that before sealing the casing 1, the circuit board 3, the battery 4 and other components are first put into the casing 1, and then the through hole 10 of the casing 1 is sealed through the sealant 2 at a preset ambient te...

Abstract

The invention provides a path recognition card and a manufacturing method of the path recognition card. The path recognition card comprises a shell, a circuit board and a battery, wherein the circuitboard and the battery are arranged in an inner cavity of the shell; the circuit board is electrically connected with the battery; a through hole for communicating the inner cavity of the shell with the external atmosphere is formed in the shell; the path recognition card is provided with the through hole, the through hole is sealed through the sealant, and the environment temperature of the sealant is higher than the storage temperature of the path recognition card when the sealant seals the through hole, so that the path recognition card not only meets the waterproof and dustproof requirements, but also avoids the condition that the shell bulges outwards in daily use.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a route identification card and a method for making the route identification card. Background technique [0002] In recent years, with the rapid development of expressway construction in my country, the continuous extension of the expressway network and the continuous expansion of the toll area, there may be a variety of driving paths between the entrance and exit of the expressway toll station. In order to be able to accurately calculate the vehicle For tolls, expressway multi-path split recognition has become an inevitable development trend, and path identification cards have emerged as the times require. Specifically, in order to determine the mileage of the vehicle on the expressway, when the vehicle enters the expressway, at the entrance of the expressway, the driver will obtain a piece of information carrying the entrance of the expressway, the entry time ...
