[0031] Embodiment 1

[0032] See also Figure 1-Figure 3 , which is a schematic structural diagram of a locking device provided in an embodiment of the present utility model, the locking device comprises a supporting mechanism 100, a connecting mechanism 300 provided on the supporting mechanism 100, and a clamping mechanism 200 provided on the connecting mechanism 300, wherein:

[0033] In order to support the handheld terminal 400, realize convenient disassembly and assembly, and provide reliable clamping capability, the support mechanism 100 includes a bottom plate 110 and an elastic pad 120 arranged on the bottom plate 110. The bottom plate 110 is arranged in the same shape as the handheld terminal 400, and its size is slightly larger than the handheld terminal 400. One end of the bottom plate 110 is a square right-angle end, and the other end is set to an M shape. The square right-angle end and the M-shaped end are both used to install the support mechanism 100 and the clamping mechanism 200 to fix the handheld terminal 400 on the bottom plate 110. In this embodiment, the bottom plate 110 is designed to be lightweight, and a square hole is opened on the bottom plate 110. Elastic pads 120 are arranged on both sides of the square hole and between the two square holes, so that when the handheld terminal 400 is clamped on the bottom plate 110, the buffering effect of the elastic pad 120 can reduce the vibration of the handheld terminal 400, thereby reducing the risk of the handheld terminal 400 falling. In addition, the bottom plate 110 is provided with a plurality of screw holes, which can be connected to a dashboard or other parts of the vehicle by bolts or other connection methods, thereby fixing the handheld terminal 400.

[0034] In order to clamp the handheld terminal 400 on the bottom plate 110, the clamping mechanism 200 includes a first clamping assembly 210 respectively arranged at the square right-angle end of the bottom plate 110, and a second clamping assembly 220 arranged on the M-shaped end of the bottom plate 110, and the first clamping assembly 210 and the second clamping assembly 220 are connected to the bottom plate 110 through a connecting mechanism 300. The first clamping assembly 210 includes a clamping member 211 and an elastic member 215 arranged on the clamping member 211, and the clamping member 211 includes a connecting portion 212 and a clamping portion 213, and the clamping portion 213 is connected to the first connecting assembly 310 on both sides thereof through the connecting portion 212. The first mounting ears 214 are symmetrically arranged on both sides of the connecting portion 212, and the two ends of the elastic member 215 are used to abut against the inner side of the first mounting ears 214 on both sides.

[0035] In order to enable the first clamping assembly 210 to be rotatably connected to the first connecting assembly 310, the first connecting assembly 310 includes an L-shaped bracket 311 symmetrically arranged on both sides of the clamping member 211, and a first connecting shaft 312 extending from the L-shaped bracket 311 to the clamping member 211. One end of the L-shaped bracket 311 is fixed to the end face of the bottom plate 110, and the first connecting shaft 312 is simultaneously passed through the first mounting ear 214 and the elastic member 215, and the two ends of the elastic member 215 are respectively against the end face of the clamping member 211 and the end face of the bottom plate 110. This technology is a prior art and is not described in detail. It is worth noting that a raised rib is provided at the top of the clamping portion 213 to play an anti-slip role when unlocking the handheld terminal 400, and the clamping portion 213 is in the shape of a lock hook to fix the handheld terminal 400 on the bottom plate 110.

[0036] Further, in order to cooperate with the first clamping assembly 210, a second clamping assembly 220 and a second connecting assembly 320 are provided at the M-shaped end of the bottom plate 110. The second clamping assembly 220 includes a support plate 221 and at least one positioning pin 222 provided on the support plate 221. The positioning pin 222 is used to penetrate into the handheld terminal 400 to position the handheld terminal 400, and its top is designed as an inclined surface for precise positioning. In addition, second mounting ears 223 are provided on both sides of the support plate 221 to connect the second connecting assembly 320 symmetrically provided on both sides of the support plate 221.

[0037] The second connection assembly 320 includes a limit plate 321 connected to the side of the bottom plate 110 and a second connection shaft 322 provided on the limit plate 321. When the limit plate 321 is fixed to the side of the bottom plate 110 by screwing, the second connection shaft 322 is just inserted into the second mounting ear 223, and the abutment plate 221 can rotate around the second connection shaft 322. In addition, a washer 330 is provided between the bottom plate 110 and the limit plate 321 to reduce the wear between the bottom plate 110 and the limit plate 321.

[0038] It is worth emphasizing that since the limit plates 321 are arranged on both sides of the base plate 110 and their height is higher than the base plate 110, when the handheld terminal 400 rests on the rest plate 221, both sides of the handheld terminal 400 rest on the limit plates 321 respectively to limit the shaking of the handheld terminal 400 in the horizontal direction.

[0039] When fixing the handheld terminal 400, the two sides of the handheld terminal 400 are held by hand, and the bottom of the terminal is directly opposite to the positioning pin 222 and then continues to move closer. After contact, the handheld terminal 400 is easily inserted into the handheld terminal 400 under the guidance of the top inclined surface of the positioning pin 222. The upper part of the handheld terminal 400 is held and pressure is applied. The handheld terminal 400 rotates around the second connecting shaft 322 along with the abutment plate 221, and the top of the handheld terminal 400 approaches the clamping member 211. When the top of the handheld terminal 400 contacts the clamping member 211, the applied pressure causes the clamping member 211 to overcome the resilience of the elastic member 215 and rotate around the first connecting shaft 312 provided on the L-shaped bracket 311 until the hook portion at the end of the clamping portion 213 moves to the clamping slot portion at the top of the handheld terminal 400. At this time, the clamping member 211 is reset under the resilience of the elastic member 215, and the clamping portion 213 is clamped into the clamping slot at the top of the handheld terminal 400. At this time, the handheld terminal 400 is locked and secure.

[0040] When taking out the handheld terminal 400, hold both sides of the terminal and extend your fingers to squeeze the raised ribs of the clamping part 213. Under the action of pressure, the clamping part 211 overcomes the resilience of the elastic part 215 and rotates around the first connecting shaft 312 provided on the L-shaped bracket 311 until the clamping part 213 is separated from the clamping slot at the top of the handheld terminal 400. Keep the finger movement and rotate the handheld terminal 400 outward. When the top of the terminal leaves the range of the clamping part 211, you can release your fingers. At this time, the handheld terminal 400 can be easily taken out.

[0041] In summary, according to a locking device proposed by the utility model, by pressing one end of the handheld terminal against the second clamping component and then rotating the first clamping component to clamp the handheld terminal on the bottom plate, the purpose of convenient disassembly and assembly is achieved, and since an elastic pad is provided on the bottom plate, the handheld terminal is prevented from falling off due to strong vibration. Specifically, the first clamping component and the second clamping component are respectively connected to the two ends of the bottom plate through the first connecting component and the second connecting component. Since the first clamping component is rotatably connected to the first connecting component, when one end of the handheld terminal is pressed against the second clamping component, the first clamping component is rotated to clamp the handheld terminal. The elastic pad on the bottom plate can also effectively reduce the vibration of the handheld terminal to prevent it from falling. The second connecting component provided on both sides of the bottom plate can also limit the shaking of the handheld terminal in the horizontal direction. The first clamping component and the second clamping component are connected to the bottom plate through the connecting mechanism, and the shaking of the handheld terminal in the horizontal direction is limited by the second connecting component, which improves the clamping ability of the handheld terminal. At the same time, the rotation locking function of the first clamping component also provides convenient disassembly and assembly capabilities.
