Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

One embodiment of the present invention provides a high-speed serial expansion interface, and the specific structure thereof is shown in fig. 1-4, which mainly includes a main body 1, a serial interface 2 fixedly connected to the front side of the main body 1, and a protection component disposed outside the serial interface 2. In particular, the protection assembly of the present invention includes two protection covers 7, the two protection covers 7 are sleeved outside the serial port 2 and are oppositely disposed, the two protection covers 7 can be kept relatively fixed after being separated from each other, and the external connection terminal 21 inserted onto the serial port 2 is pushed open when the two protection covers 7 are folded together, so as to easily disconnect, save time and labor, and avoid accidental injury.

As a specific implementation structure of the present invention, two sides of the two protective covers 7 are fixedly connected with a connecting member 6, one end of the connecting member 6 is fixedly connected with a moving block 5, two sides of the serial port 2 are provided with sliding rods 3, the sliding rods 3 penetrate through the connecting member 6 and are slidably connected with the connecting member 6, two ends of the sliding rods 3 are fixedly connected with a fixed plate 4, the fixed plate 4 is fixedly connected to one side of the main body 1, a first spring 8 is fixedly connected between the moving block 5 and the fixed plate 4, the first spring 8 is sleeved outside the sliding rods 3, and the moving block 5 and the fixed plate 4 are connected through the first spring 8, so that the moving block 5 is stably moved and can be automatically reset in a later period, one side of each moving block 5, which is far away from each other, is fixedly connected with a. One side of the connecting plate 10 is fixedly connected with a rack 11, the tooth surface of the rack 11 is provided with a one-way limiting claw 14 in a manner of facing the tooth surface, the one-way limiting claw 14 is in meshing contact with the rack 11 so as to limit the movement of the rack 11 in a one-way manner in a natural state, and the one-way limiting claw 14 is in meshing contact with the rack 11 so that the rack 11 can be limited by the one-way limiting claw 14, and the two racks 11 can be prevented from approaching each other in the normal condition and only can move away from each other, namely the rack 11 can move in a one-way manner on the premise that the one-way limiting claw 14; specifically, as shown in fig. 4-5, it should be noted that the supporting plate 13 and the one-way restricting claws 14 in fig. 5 are not connected to the connecting plate 10, but only the visual misalignment caused by the explosion diagram. One end of the one-way limiting claw 14 is fixedly connected with a rotating rod 25, a supporting plate 13 is arranged outside the rotating rod 25 at intervals, the supporting plate 13 is fixedly connected to the main body 1, a torsion spring 12 connected with the supporting plate 13 is sleeved outside the rotating rod 25, the torsion spring 12 can easily twist in the forward twisting direction, so that the one-way limiting claw 14 can easily rotate without blocking the rack 11, but when the torsion spring 12 is reversely twisted, the torsion spring 12 is difficult to rotate in a self-adaptive manner, at the moment, the one-way limiting claw 14 blocks the corresponding movement of the rack 11 (for example, the rack 11 on the upper side cannot move downwards and can be blocked by the one-way limiting claw 14), the rotating rod 25 is prevented from reversely rotating through the torsion spring 12 (the rotating rod 25 rotates forwards when the rack 11 on the upper side moves upwards), thereby the limiting effect of the one-way limiting claw 14 on the rack 11 is, thereby leaving the serial interface 2 exposed to be connected.

The design of the limiting structure of the one-way limiting claw 14 for the rack 11 can be in various forms, except for the structure of the torsion spring 12, a ratchet mechanism 23 can be specifically adopted to replace the torsion spring 12, the effect is better, and the one-way limiting claw is particularly suitable for being used in cooperation with a large serial interface 2 with heavier weight, as shown in fig. 7, the torsion spring 12 of the above embodiment is removed, the rotating rod 25 is directly installed on the ratchet, and the pawl 26 is rotated to be installed on the supporting plate 13. Of course, the torsion spring 12 may not be removed to enhance the one-way restricting effect, but the torsion spring 12 may be connected to the end surface of the ratchet toward the one-way restricting pawl 14 instead of the support plate 13 so that the torsion spring 12 and the ratchet mechanism 23 perform the same function.

Specifically, when the serial interface 2 is inserted and butted, the connecting plate 10 is pushed up and down by a single hand, the pulling rod 9 is pulled by the connecting plate 10, so that the pulling rod 9 pulls the moving blocks 5 at the two sides of the serial interface 2 to move, when the moving blocks 5 move, thereby the two protective covers 7 are driven by the connecting piece 6 to be separated, when the protective covers 7 are separated, the serial interface 2 is exposed, the protection of the serial interface 2 is facilitated, the dustproof treatment of the serial interface 2 when not used at ordinary times is avoided, meanwhile, when the racks 11 are separated from each other, the one-way limiting claw 14 is connected with the torsion spring 12 through the rotating rod 25 to clamp the separated racks 11, which is beneficial to limiting the connecting plate 10, the protective assembly is thus in an open state, in which the external connection terminals 21 are plugged into the serial interface 2, as shown in fig. 6, i.e. the external connection terminals 21 are covered on the interface housing 201.

Referring to fig. 4 and 5 again, the other side of the connecting plate 10 is fixedly connected with a pushing plate 15 opposite to the rack 11 and preferably arranged in a collinear manner, and the lower part of the pushing plate 15 is fixedly connected with an arc-shaped block 16 protruding towards one surface of the one-way limiting claw 14; correspondingly, the upper side and the lower side of the serial interface 2 are respectively provided with a tilting plate 19, and the tilting plate 19 is positioned at the rear side of the protective cover 7. Meanwhile, the seesaw 19 can be connected between the two transverse plates 17 in a front-back rotating manner, and the transverse plates 17 are fixedly connected to the surface of the main body 1; for example, the hinge shaft 22 can be fixed between the two cross plates 17, the tilting plate 19 is hinged between the two cross plates 17 through the hinge shaft 22, and the two cross plates 17 enable the tilting plate 19 to rotate only in the front-rear direction. The top of the transverse plate 17 is fixedly connected with a convex block 20, the convex block 20 and the arc-shaped block 16 are arranged oppositely, so that mutual extrusion of the convex block 20 and the arc-shaped block 16 is facilitated, and one end of the transverse plate 17 separates an external connection terminal 21 from the serial interface 2. A second spring 18 is fixedly connected to a surface of the seesaw plate 19 facing the main body 1, and the second spring 18 is fixedly connected to a side of the main body 1.

The working principle of the embodiment is as follows: when the external connection terminal 21 is plugged into the serial interface 2, the two connecting plates 10 are respectively poked by a forefinger and a thumb through one hand, at the moment, the connecting plates 10 drive the corresponding pulling rods 9 on the one hand, so that the pulling rods 9 pull the corresponding moving blocks 5 on two sides of the serial interface 2 to move and separate, the two protective covers 7 are driven to separate under the guiding action of the sliding rods 3 through the corresponding connecting pieces 6, and finally, the serial interface 2 is completely exposed so as to plug the external connection terminal 21. Meanwhile, the two connecting plates 10 on the other hand also drive the racks 11 on the respective sides to move, so that the upper and lower racks 11 are also away from each other, and the protrusions 20 on the respective sides are gradually separated from the arc blocks 16 in the process of the away-from, so as to release the pressure on the second spring 18 on the tilting plate 19, so that the tilting plate 19 performs lever-motion-like hinged rotation around the hinge shaft 22 under the action of the elastic jacking force of the second spring 18, and the end, close to the serial port 2, of the tilting plate 19 is attached to or close to the surface of the main body 1, or when the serial port 2 has a connecting bottom plate fixed to the surface of the main body 1, the tilting plate is attached to the connecting bottom plate. As shown in fig. 6, when the external connection terminal 21 is inserted into the serial port 2 and needs to be removed after use, the one-way limiting claws 14 are manually rotated to separate the one-way limiting claws 14 from the corresponding racks 11 and release the racks 11, specifically, there are various operation methods, for example, the one-way limiting claw 14 on the upper side can be manually shifted upward to separate the one-way limiting claw 14 from the rack 11, the rack 11 on the upper side is released and moved downward under the elastic force of the second spring 18 to be reset, and the one-way limiting claw 14 on the lower side is similarly operated at the same time, so that the two racks 11 are folded with each other and the serial port 2 is covered again. In addition, in the process that the two racks 11 approach each other and move, each group of the paired protruding blocks 20 is in contact with the arc-shaped block 16 again, the second spring 18 is extruded, the tilting plate 19 makes a lever motion around the hinge shaft 22, so that one end, close to the serial port 2, of the tilting plate 19 tilts towards the side away from the surface of the main body 1, the external connection terminal 21 inserted on the serial port 2 is pushed outwards, the purpose that the external connection terminal 21 is separated from the serial port 2 by the tilting plate 19 is achieved, and compared with the existing process that the external connection terminal 21 is pulled out difficultly, the process is safe and labor-saving.

As another embodiment, as shown in fig. 8, in order to manually and directly rotate the one-way restricting pawl 14 to release the restriction of the rack 11, when only the torsion spring 12 is provided as the restricting member, the end portion of the above-mentioned rotating lever 25 of the one-way restricting pawl 14 may be provided with an L-shaped handle 24 for rotation.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
