[0026] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0027] This embodiment proposes a vehicle-mounted keyboard flipping device, the overall structure of which is as follows: Figure 1As shown, it includes a key ring 1, a locking pin 2, a right L-shaped plate 3, a lock body 4, a compression spring 5, a nut 6, a keyboard pressure plate 7, a pin 8, a left L-shaped plate 9, a keyboard bracket 10, a fixing bolt 11, and a keyboard 12.
[0028] The keyboard pressure plates 7 are formed by Z-shaped bending, and the bottom and side edges of the keyboard 12 are fixedly connected to the six keyboard pressure plates 7. The keyboard bracket 10 is fixedly connected to each keyboard pressure plate 7 by multiple fixing bolts 11, so that the side edges of the keyboard 12 are bonded to the inner surface of the keyboard bracket 10, clamping the keyboard 12 between the keyboard bracket 10 and the keyboard pressure plates 7. The keyboard pressure plates 7 and the keyboard bracket 10 can be adjusted according to the external dimensions of the keyboard 12.
[0029] Two pins 8 are welded to the left side of the keyboard tray 10; one pin 8 serves as a rotating pin, and the other as a sliding pin. One pin 8 is welded to the right side of the keyboard tray 10, also serving as a rotating pin, and a lock body mounting hole is machined to the side of the right-side pin 8. The two rotating pins are coaxially aligned, and the left-side sliding pin is coaxially aligned with the lock body mounting hole. A lock body 4 is welded to the inner side of the lock body mounting hole, and a through stepped hole is machined in the center of the lock body 4.
[0030] The bottom plates of the right L-shaped plate 3 and the left L-shaped plate 9 are provided with mounting holes (one or more). The right L-shaped plate 3 and the left L-shaped plate 9 are fixed to the seats or interior panels of the vehicle using bolts through the mounting holes to ensure the stability of the keyboard structure during flipping. The side plates of the right L-shaped plate 3 and the left L-shaped plate 9 are respectively provided with rotating pin limit holes and sliding holes. The two left and right rotating pin limit holes are used to insert the left and right rotating pins of the keyboard bracket 10, and the keyboard 12 can rotate around the two rotating pins with the keyboard bracket 10.
[0031] The sliding hole of the left L-shaped plate 9 is used to insert the left sliding pin of the keyboard bracket 10. When the keyboard 12 rotates around the rotating pin, the left sliding pin slides in the sliding hole of the left L-shaped plate 9. The sliding hole of the right L-shaped plate 3 is used to insert the locking pin 2, and locking pin limiting holes are machined at both ends of the sliding hole. When the locking pin 2 is fully inserted into the stepped hole of the lock body 4, the limiting cylindrical surface on the locking pin 2 cooperates with the locking pin limiting hole, limiting the locking pin 2 at one of the locking pin limiting holes, thereby fixing the keyboard 12 at the current rotation termination position. When the locking pin 2 is pulled out from the stepped hole of the lock body 4, the limiting cylindrical surface of the locking pin 2 disengages from the locking pin limiting hole, and when the keyboard 12 rotates around the rotating pin, the locking pin 2 can slide in the sliding hole.
[0032] The outer end of the locking pin 2 is connected to the key ring 1, and the inner end of the locking pin 2 is inserted into the stepped hole of the lock body 4 and connected to the nut 6 located in the stepped hole through external threads. The compression spring 5 is sleeved on the pin of the locking pin 2 located in the lock body 4, and the two ends of the compression spring 5 abut against the stepped surface of the stepped hole and the nut 6 respectively, forming an actuator, such as... Figure 4 As shown. The locking pin 2 has a limiting cylindrical surface that mates with the locking pin limiting hole. When the key ring 1 is pulled, it causes the locking pin 2 and nut 6 to tighten the compression spring 5. At this time, the limiting cylindrical surface of the locking pin 2 disengages from the locking pin limiting hole, allowing the keyboard 12 to be rotated to a suitable position, realizing the conversion between the keyboard 12's stored and opened positions. The locking pin 2 slides to the corresponding locking pin limiting hole as the keyboard 12 is rotated. After releasing the key ring 1, the limiting cylindrical surface of the locking pin 2 engages with the locking pin limiting hole, fixing the keyboard 12 in the rotation termination position, as shown. Figure 5 and 6 As shown in the image, keyboard 12 frees up more space when flipped and stored.
[0033] In this embodiment, the right L-shaped plate 3, the keyboard pressure plate 7, the left L-shaped plate 9, and the keyboard bracket 10 are all made of thin steel plate with a thickness of 3mm.
[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
