Description

Technical Field

[0001] The utility model relates to the technical field of electronic labels, and in particular to an electronic label with a replaceable sensor and waterproof. Background Art

[0002] Electronic waybills refer to the use of electronic screens to display logistics information, replacing paper waybills, and displaying information such as the shipper and the place of shipment. Among them, electronic waybills are often used in cold chain logistics systems. Since they need to work in a low temperature and high humidity environment for a long time, in order to prevent moisture from entering the product and causing damage to the product, the structure needs to be waterproofed. Because it is sometimes only used for positioning, there is no need for external sensors, which makes it convenient to remove external sensors. The sensors described here include but are not limited to: temperature sensors, humidity sensors, pressure sensors, displacement sensors, flow sensors, force sensors, etc. In order to solve the above problems, one approach is to assemble the sensor and the host by directly connecting them with wires, which has poor dust and water resistance and is inconvenient to replace; another approach is to connect the sensor plug to the host socket to facilitate the replacement of the sensor, but the host socket is not a dust and water proof structure, and dust and water vapor can easily enter the product and cause damage to the product.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods.

[0022] like Figure 3-4 , Figure 6 As shown, an embodiment of the utility model provides an electronic waybill with replaceable sensors and is waterproof. In this embodiment, it is used in a cold chain logistics system; it includes a main body 1, which can be plugged with at least one sensor 2, that is, the main body includes at least one socket plugged with the sensor; the sensor includes a main body 201 and a plug 202 connected thereto; in order to be plugged with the sensor, at least one waterproof socket 3 plugged with the plug is provided in the main body 1, and a sealing ring 4 for sealing the contact position between the waterproof socket and the main body 1 is provided on the waterproof socket, and at least one flexible rubber plug 5 for covering the opening of the waterproof socket is provided on the main body.

[0023] Specifically, in this embodiment, Figure 3-5 As shown, the flexible plug 5 includes a flexible flat plate 501, and a flexible plug-in column 502 which is arranged on the surface of the flat plate and is integrally formed with the flat plate and perpendicular to the flexible plug-in column 502; the body 1 is provided with a plug-in hole 101 located on one side of the waterproof socket 3. Here, during assembly, the flexible plug-in column 502 is inserted into the plug-in hole 101, so that the flexible plug 5 and the body 1 are always connected together; in order to prevent the flexible plug 5 from being separated from the body 1, an anti-dropping convex ring (not shown) is provided on the inner wall of the plug-in hole 101, and an undercut portion 502a is provided on the flexible plug-in column 502; when the flexible plug-in column is inserted into the plug-in hole, the undercut portion abuts against the anti-dropping convex ring; since the flexible plug-in column 502 is made of flexible material, it can be deformed during insertion, and when the undercut portion 502a enters the plug-in hole, it returns to its original state and abuts against the anti-dropping convex ring, thereby preventing the flexible plug 5 from falling off.

[0024] In order to connect more sensors 2, the waterproof socket 3, the plug hole 101 and the flexible rubber plug 5 are all two; that is, the body 1 can be connected to two sensors 2. Although it is described in detail in this embodiment that the electronic waybill can be connected to two sensors 2, it is obvious that it can also be connected to different numbers of sensors according to actual needs.

[0025] When the waterproof socket 3 is not in use, in order to seal the waterproof socket, at least one square countersunk hole 102 is provided in the surface of the main body 1 where the waterproof socket 3 is provided, and the opening of the waterproof socket is located in the square countersunk hole; a square flexible sealing body 503 is also provided on the surface of the flexible flat plate 501, which is located on one side of the flexible plug-in column 502 and is adapted to the square countersunk hole; the square flexible sealing body is integrally formed with the flexible flat plate; when the square flexible sealing body 503 is embedded in the square countersunk hole 102, the square flexible sealing body is made of flexible material, and has a waterproof and dustproof effect after interference fit with the square countersunk hole.

[0026] like Figure 1-4 As shown, because other interfaces located on one side of the waterproof socket 3 need to be provided in the main body 1, a first square countersunk hole 103 located on the other side of one of the plug holes 101 and a second square countersunk hole 104 located on the other side of the other plug hole are also provided in the main body 1.

[0027] Specifically, in this embodiment, Figure 3-4 As shown, a TYPE-C interface 105 is provided in the first square counterbore 103 , and a SIM card interface 106 is provided in the second square counterbore 104 .

[0028] like Figure 4-5 As shown, in order to seal the first square countersunk hole 103 and the second square countersunk hole 104, a first flexible sealing body 504 adapted to the first square countersunk hole 103 is provided on the flexible flat plate 501 of one of the flexible rubber plugs 5, and the flexible plugging column 502 is located between the first flexible sealing body and the square flexible sealing body 503 on the flexible rubber plug. A first flexible sealing body 504 adapted to the second square countersunk hole 104 is provided on the flexible flat plate 501 of the other flexible rubber plug 5, and the flexible plugging column 502 is located between the first flexible sealing body and the square flexible sealing body 503 on the flexible rubber plug.

[0029] like Figure 2 As shown, when an external sensor 2 is needed, only half of the flexible rubber plug 5 needs to be uncovered, that is, the part covering the waterproof socket 3, without uncovering the part where the first flexible sealing body 504 is located.

[0030] To sum up, compared with existing similar products, the sensor 2 of the electronic waybill of the utility model is pluggable, and the sensor can be installed or removed as needed. However, when the sensor is not needed, the waterproof socket 3 connected to the sensor can be well sealed, which has the effect of waterproof and dustproof.

[0031] In the above description, it should be noted that the terms "installed", "connected", "connected" and other corresponding terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two components; "provided in" should be understood as "installed in, set in", including fixed installation, movable installation and other installation methods.

[0032] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. The preferred embodiments of the utility model are given in the drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Any equivalent structure made by using the contents of the utility model specification and drawings, directly or indirectly used in other related technical fields, is also within the scope of protection of the utility model patent.
