All other embodiments that can be derived by a person skilled in the art from the embodiments given herein without making any creative effort fall within the protection scope of the present application.

Referring to fig. 1-4, the application discloses an ultrahigh frequency read-write module, which includes a protective housing, a read-write device 3 and a first shock absorption assembly 4, wherein the protective housing includes a casing 1 and a cover 2, the casing 1 is designed as an internal cavity, and has an opening on one side, the cover 2 is used for covering the opening on the casing 1, the read-write device 3 is installed in the casing 1, the first shock absorption assembly 4 has four groups, three groups of first shock absorption assemblies 4 are installed in the casing 1 and are respectively connected with the left side, the right side and the bottom of the read-write device 3, the remaining group of first shock absorption assemblies 4 are installed on the cover 2 and are connected with the top of the read-write device 3, the first shock absorption assembly 4 includes a first support plate 41 and a first elastic member 42, the first support plate 41 can be connected with the read-write device 3, one end of the first elastic member 42 is connected with the inner wall of the casing 1 or the cover 2, and the other end is connected with the first support plate 41.

The two ends of the first abutting plate 41 are designed to be arc-shaped.

Referring to fig. 2 and fig. 3, four sets of shock absorption assemblies 4 are all installed in the protective housing and are respectively in contact connection with four sides of the read-write device 3, so that the read-write device 3 has certain shock absorption and protection effects in a plane dimension, and because the read-write device 3 is installed in the housing 1 in an insertion manner, both ends of the first abutting plate 41 are designed in an arc surface shape, and the read-write device 3 can abut against the first abutting plates 41 on both sides in the housing 1 when being installed, and because of the arc surface design of the first abutting plates 41, the read-write device 3 can be easily installed in the housing 1 and is clamped and fixed by the first abutting plates 41 of the three sets of shock absorption assemblies 5 in the housing 1.

Furthermore, a bayonet 11 is arranged on one side of the shell 1, a buckle 21 is arranged on the cover body 2 corresponding to the bayonet 11, and when the cover body 2 covers the opening on the shell 1, the buckle 21 is clamped with the bayonet 11.

Specifically, when the cover 2 covers the opening of the housing 1, the buckle 21 is clamped with the bayonet 11 due to its own elastic force, wherein it should be noted that the protective case is entirely made of a plastic material with a certain elastic force, if the protective case is made of other metal materials, the read/write device 3 needs to release a high-frequency magnetic field to work, the protective case made of metal materials is likely to interfere with the magnetic field to a certain extent, which affects the working efficiency of the read/write device 3, and then the metal materials have a larger weight and density than the plastic materials, and are not convenient to move during the use, and finally the metal materials have a higher cost, so the protective case in this embodiment is made of plastic materials, and the end of the buckle 21 is provided with pressing stripes, as shown in fig. 3, so that a user can press the pressing stripes at the end of the buckle 21, make buckle 21 and bayonet 11's one end retract towards lid 2 is inside, when closing the opening part of casing 1 with lid 2 lid, release buckle 21, at this moment, buckle 21 just can kick-back and block into in the bayonet 11 that corresponds for lid 2 is fixed on casing 1.

Furthermore, the reading and writing device 3 is provided with a clamping piece 31, a second shock absorption component 5 is arranged in the shell 1 corresponding to the clamping piece 31, and the reading and writing device 3 is clamped with the second shock absorption component 5 through the clamping piece 31 when being installed in the shell 1.

The second cushioning component 5 includes a limiting member 51, a second abutting plate 52 and a second elastic member 53, the limiting member 51 is installed in the casing 1 and can be clamped with the clamping member 31, the second abutting plate 52 is disposed between the limiting member 51 and the clamping member 31 and cooperates with the limiting member 51 to clamp the clamping member 31, one end of the second elastic member 53 is connected with the inner wall of the casing 1, and the other end is connected with the second abutting plate 52.

Specifically, the read-write device 3 provides a shock absorption and protection effect perpendicular to a plane dimension in a protection shell, except for a shock absorption and protection structure of the plane dimension, the second shock absorption assembly 5 provides a shock absorption and protection effect perpendicular to the plane dimension, wherein as shown in fig. 4, the structures of the clamping member 31 and the limiting member 51 are similar and are both L-shaped structures, and when the clamping member and the limiting member are matched, the clamping member and the limiting member are in a mutual overlapping manner, as shown in fig. 3, the limiting member 51 functions to assist the read-write device 3 to be installed at a middle position of the shell 1, so that the first shock absorption assemblies 4 on two sides of the shell 1 can protect the read-write device 3, but the limiting member 51 is not set up, the read-write device 3 is directly installed therein, once the internal shaking condition caused by collision occurs, the read-write device 3 can have a large shaking reaction therein, although the first elastic member 42 can buffer off a certain shock, but has a large buffering stroke, and may also bring a certain degree of damage to the read-write device 3, therefore, the limit part 51 and the clamping part 31 are connected in an overlapping manner, so that the buffering stroke of the first elastic part 42 is shortened, the ultrahigh frequency read-write module can achieve the protection effect while playing a role in buffering the read-write device 3, as shown in fig. 4, the second buffering component 5 provides buffering and protection effects perpendicular to the plane dimension, namely, the second abutting plate 52 cooperates with the limit part 51 to clamp the clamping part 31 under the action force of the second elastic part 53, so that the read-write device 3 can have multidirectional buffering and protection functions in the protective shell.

Further, the housing 1 is provided with a plurality of heat dissipation holes 6.

Specifically, because the read-write device 3 can generate certain heat in the running process, if the read-write device 3 is overheated, the internal components are easily damaged, and further the working efficiency of the read-write device 3 is reduced. It should also be noted that while the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that a variety of changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the application, the scope of which is defined in the appended claims and their equivalents.
