[0026] Please refer to Figures 1 to 8 , an ejection mechanism of a civil aviation electronic device provided in an embodiment of the present application includes a mounting tray 1 and a handheld terminal 2, the mounting tray 1 is provided with a receiving groove 11, a buckle 12, a tongue 3, a button 4 and a push rod 5, the receiving groove 11 is used to embed the handheld terminal 2, the buckle 12 is fixedly arranged in the receiving groove 11, the tongue 3 is slidably arranged at the end opposite to the buckle 12, the tongue 3 extends into the receiving groove 11 after sliding and forms a locking connection with the handheld terminal 2 with the buckle 12, the button 4 is connected to the tongue 3 so as to push the tongue 3 out of the receiving groove 11 under the action of external force, and the push rod 5 can lift the end of the handheld terminal 2 close to the tongue 3 after the tongue 3 exits the receiving groove 11.

[0027] The center of the upper surface of the mounting tray 1 is recessed downward to form a receiving slot 11. This receiving slot 11 is rectangular, and its size and depth are adapted to the handheld terminal 2, allowing the handheld terminal 2 to be fully embedded within the receiving slot 11. The handheld terminal 2 is provided with a latching slot 21 on either side, one of which is arranged along the length of the handheld terminal 2. After the handheld terminal 2 is inserted into the receiving slot 11, the two latching slots 21 cooperate with the latch 12 and the latch tongue 3 to form a latching connection with the handheld terminal 2.

[0028] The buckle 12 is a fixed design, located on one side wall of the receiving slot 11; the tongue 3 is a sliding design, located on the other side wall of the receiving slot 11 and opposite the buckle 12. When placing the handheld terminal 2, one side of the handheld terminal 2 is first placed into the receiving slot 11 so that the slot 21 on that side engages with the buckle 12. Then, the other side of the handheld terminal 2 is pressed into the receiving slot 11 so that the slot 21 on that side engages with the tongue 3, thereby securing the handheld terminal 2 in the receiving slot 11.

[0029] When the handheld terminal 2 needs to be used, the button 4 is pressed to drive the tongue 3 to slide, so that the tongue 3 is withdrawn from the receiving groove 11. Under the lifting force of the push rod 5, the end of the handheld terminal 2 close to the tongue 3 will be pushed upward, so that the side of the handheld terminal 2 protrudes out of the receiving groove 11, thereby making it easier for the user to take the handheld terminal 2.

[0030] According to some embodiments of the present application, a mounting hole is provided on the mounting tray 1, and the mounting hole is connected to the bottom of the accommodating groove 11. The push rod 5 is slidably set in the mounting hole, and a first compression spring 8 is provided in the mounting hole. The first compression spring 8 is used to apply an upward thrust to the push rod 5 to push the push rod 5 to slide upward in the mounting hole, so that the push rod 5 can extend into the accommodating groove 11 to lift the handheld terminal 2.

[0031] The aforementioned mounting hole is vertically arranged, its axis perpendicular to the bottom surface of the receiving slot 11. It is positioned near the latch 3, thereby pushing the handheld terminal 2 toward one end of the latch 3. The lower end of the push rod 5 has an inner hole, into which the upper end of the first compression spring 8 resides. After the latch 3 is withdrawn from the receiving slot 11 by pressing the button 4, the push rod 5 slides along the mounting hole and extends into the receiving slot 11, thereby lifting the handheld terminal 2 upward.

[0032] Because the ejector pin 5 is designed to eject vertically, the first compression spring 8 can be selected with an appropriate Hooke's coefficient based on the weight of the handheld terminal 2 to maintain a suitable ejection speed for the handheld terminal 2. Furthermore, the ejector pin 5 is designed to slide with the mounting hole, making the ejection design of the ejector pin 5 simple and reliable, and effectively preventing the ejector pin 5 from getting stuck.

[0033] According to some embodiments of the present application, an annular protrusion is provided on the end of the push rod 5 away from the accommodating groove 11, and an annular limiting step is provided at the end of the mounting hole that passes through the accommodating groove 11. When the push rod 5 is lifted, axial limitation is achieved by the annular protrusion and the limiting step, thereby preventing the push rod 5 from falling out of the mounting hole when rising.

[0034] The mounting hole has a stepped structure near the end where the push rod 5 extends. This means a stopper step is formed on the inner wall of the mounting hole, and the inner diameter of the stopper step is smaller than the outer diameter of the annular protrusion. As the push rod 5 rises, the annular protrusion at the lower end of the push rod 5 and the stopper step at the upper end of the mounting hole create a thrust stop, preventing the push rod 5 from falling out of the mounting hole during the ascent.

[0035] According to some embodiments of the present application, the mounting tray 1 is provided with a spring seat 7, and the spring seat 7 is provided with a second compression spring 9. The second compression spring 9 is connected to the latch 3 to push the latch 3 into the receiving slot 11. When the latch 3 exits the receiving slot 11, the second compression spring 9 is compressed by the latch 3 to store force.

[0036] Specifically, a fixing hole is provided on the spring seat 7, the size of the fixing hole is adapted to the outer diameter of the second compression spring 9, one end of the second compression spring 9 is provided in the above-mentioned fixing hole to prevent the second compression spring 9 from detaching from the spring seat 7, and the other end of the second compression spring 9 is connected to the tongue 3 to push the tongue 3 into the accommodating groove 11 to cooperate with the slot 21 on the handheld terminal 2.

[0037] According to some embodiments of the present application, the mounting tray 1 is provided with a mounting slot, the button 4 is slidably disposed within the mounting slot, and tongue holes are provided on both sides of the mounting slot, the tongue holes extending through both sides of the mounting slot, and the latch 3 is slidably disposed within the tongue holes. The button 4 can slide within the mounting slot, and since the button 4 is connected to the latch 3, the latch 3 can be driven to move, causing the latch 3 to exit the receiving slot 11, thereby separating the front end of the latch 3 from the latch slot 21 on the handheld terminal 2.

[0038] Specifically, the above-mentioned mounting groove is arranged in the vertical direction, the tongue hole is arranged in the horizontal direction, and the two ends of the tongue hole are set to be through, so that one end of the tongue hole is connected to the accommodating groove 11, so that the front end of the tongue 3 can extend into the accommodating groove 11; after the other end of the tongue hole is penetrated, the tongue 3 can be connected to the second compression spring 9, and the spring force is used to reset the tongue 3.

[0039] According to some embodiments of the present application, the button 4 is provided with a through hole 41 for inserting the latch tongue 3. Matching inclined sliding pairs are provided on both sides of the through hole 41 and the sides of the latch tongue 3. When an external force acts on the button 4, the inclined sliding pairs push the latch tongue 3 out of the receiving slot 11. By designing the latch tongue 3 and the button 4 as an inclined pair linkage structure, under the action of the second compression spring 9, the design of the latch tongue 3 and the button 4 is simple and reliable, and the problem of the latch tongue 3 and the button 4 being stuck can be effectively avoided.

[0040] Specifically, first inclined surfaces 42 are provided on either side of the through-hole 41 of the button 4, and matching second inclined surfaces 32 are provided on either side of the latch 3. These first inclined surfaces 42 and second inclined surfaces 32 form a matching inclined sliding pair. When the button 4 slides downward under the action of an external force, the first inclined surfaces 42 act on the second inclined surfaces 32, pushing the latch 3 to slide, thereby allowing the front end of the latch 3 to exit the receiving slot 11.

[0041] According to some embodiments of the present application, the latch tongue 3 is provided with an axial step 31 in the sliding direction, and the inclined sliding pair is provided on the end surface of the axial step 31. That is, the latch tongue 3 is stepped in the longitudinal direction, and the surface of the axial step 31 facing the front end of the latch tongue 3 is the second inclined surface 32. By providing the axial step 31 on the latch tongue 3, when the second compression spring 9 pushes the latch tongue 3 back under the spring force, the thrust of the axial step 31 on the latch tongue 3 can limit the length by which the front end of the latch tongue 3 extends into the receiving slot 11.

[0042] According to some embodiments of the present application, the end of the tongue 3 extending into the receiving groove 11 has an upper inclined surface 33, and the handheld terminal 2 has a lower inclined surface 22. When the handheld terminal 2 is embedded in the receiving groove 11, the lower inclined surface 22 contacts the upper inclined surface 33 to push the tongue 3 out of the receiving groove 11.

[0043] When placing the handheld terminal 2, one side of the handheld terminal 2 is first placed into the receiving slot 11 so that the slot 21 on that side engages with the buckle 12. Then, the other side of the handheld terminal 2 is pressed into the receiving slot 11 so that the slot 21 on that side engages with the latch 3. During the process of pressing the handheld terminal 2 into the receiving slot 11, the lower inclined surface 22 on the handheld terminal 2 and the upper inclined surface 33 on the latch 3 come into contact and press, compressing the second compression spring 9, thereby pushing the front end of the latch 3 to gradually exit the receiving slot 11.

[0044] When the handheld terminal 2 is fully inserted into the receiving slot 11, the spring force of the second compression spring 9 automatically pushes the latch 3 to reset. At this time, the front end of the latch 3 enters the slot 21 on the handheld terminal 2 to form a fit, thereby preventing the handheld terminal 2 from escaping the receiving slot 11.

[0045] According to some embodiments of the present application, an L-shaped spring clip 6 is provided on the mounting tray 1, one end of the L-shaped spring clip 6 abuts against the lower end of the first compression spring 8, and the first compression spring 8 pushes the push rod 5 to slide upward in the mounting hole, so that the push rod 5 extends into the receiving groove 11 to lift the handheld terminal 2, and the other end of the L-shaped spring clip 6 is connected to the tongue 3 to push the tongue 3 into the receiving groove 11.

[0046] Specifically, the lower end of the first compression spring 8 abuts against the L-shaped spring piece 6 , and a recess for positioning is formed on the L-shaped spring piece 6 , and the lower end of the first compression spring 8 is located in the recess.

[0047] The L-shaped spring piece 6 can be made of stainless steel, and the other end of the L-shaped spring piece 6 abuts against the rear end of the tongue 3. When the button 4 is pressed to make the front end of the tongue 3 exit the receiving slot 11, the end of the L-shaped spring piece 6 will be deformed, and the elastic restoring force of the L-shaped spring piece 6 can be used to restore the tongue 3, even if the front end of the tongue 3 extends into the receiving slot 11.

[0048] In the present application, one end of the second compression spring 9 is disposed on the spring seat 7, and the other end abuts the side of the L-shaped spring clip 6 facing away from the rear end of the latch 3. This allows the second compression spring 9 and the L-shaped spring clip 6 to jointly contribute to the reset of the latch 3 and the button 4. Furthermore, because the latch 3 and the button 4 are designed as a ramp-type linkage structure, the combined action of the second compression spring 9 and the L-shaped spring clip 6 makes the design of the latch 3 and the button 4 simple and reliable, effectively preventing the latch 3 and the button 4 from becoming stuck. Furthermore, the L-shaped spring clip 6 not only secures the first compression spring 8 but also contributes to the reset of the latch 3 and the button 4. This design greatly simplifies the structural design of the ejection mechanism.

[0049] In the present application, the handheld terminal 2 is embedded in the receiving groove 11 on the mounting tray 1, and the handheld terminal 2 is connected by the buckle 12 and the tongue 3. At the same time, by connecting the button 4 with the tongue 3, the tongue 3 can be pushed out of the receiving groove 11 under the action of an external force. The first compression spring 8 can push the push rod 5 into the receiving groove 11 to lift the handheld terminal 2. The second compression spring 9 cooperates with the L-shaped spring piece 6 to reset the tongue 3. The structural design of the pop-up mechanism is simple, which can ensure the pop-up speed of the handheld terminal 2, so that the handheld terminal 2 can be effectively popped out, and at the same time improves the reliability of the pop-up mechanism and avoids the pop-up mechanism from getting stuck.

[0050] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
