[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a UAV data transmission device that facilitates the replacement of probes, including a UAV 1, a gimbal 2 at the lower end of the UAV 1, the gimbal 2 being connected to a probe 3 via a quick-change assembly 4, the quick-change assembly 4 including a first connector 41, a second connector 42 and a sliding sleeve 43, the first connector 41 including a base 411 and a connecting post 412, the sliding sleeve 43 being slidably fitted on the base 411, the connecting post 412 having a slot 413 with a retaining bead 414 inside the slot 413, the second connector 42 including a pin 421 with a slot 422 with the retaining bead 414 embedded in the slot 422, and the sliding sleeve 43 including a pressure sleeve 431.

[0026] Use screws to install the first connector 41 onto the gimbal 2, and use screws to install the second connector 42 onto the housing of the probe 3. When installing the probe 3, simply insert the second connector 42 of the probe 3 into the first connector 41 of the gimbal 2 to achieve a fixed connection between the second connector 42 and the first connector 41, that is, to achieve a fixed connection between the gimbal 2 of the UAV 1 and the probe 3. When replacing the probe 3, simply install the corresponding second connector 42 on another set of probe 3 housings.

[0027] The first connector 41 and the second connector 42 together constitute the quick-change assembly 4, such as Figure 1 and Figure 2 As shown, the first connector 41 and the second connector 42 can be quickly connected and quickly disconnected. The quick-change component 4 improves the efficiency of assembling and disassembling the probe 3, and facilitates the replacement of different types of probe 3.

[0028] A spring 415 is fitted onto the connecting post 412. One end of the spring 415 is fixedly connected to the base 411, and the other end of the spring 415 is fixedly connected to the pressure sleeve 431. In the initial state, the position of the sliding sleeve 43 is as follows: Figure 1 As shown, the pressure sleeve 431 of the sliding sleeve 43 presses the retaining bead 414, and the retaining bead 414 retracts into the groove 413.

[0029] The locking bead 414 is connected to the slot 413 by an elastic element 418. The locking bead 414 and the slot 413 are elastically connected, and the locking bead 414 can move within the slot 413. The elastic element 418 prevents the locking bead 414 from falling out.

[0030] The connecting post 412 includes a insertion hole 419, the pin 421 of the second connector 42 is embedded in the insertion hole 419 of the connecting post 412, and the slot 422 of the connecting post 412 is aligned with the bead 414.

[0031] When a certain external force is applied to the sliding sleeve 43, the spring 415 is compressed, and the sliding sleeve 43 slides along the base 411. The pressure sleeve 431 of the sliding sleeve 43 is removed, and at this time, the retaining bead 414 can move in the slot 413 under the action of the external force. The pin 421 of the second connector 42 is inserted into the insertion hole 419 of the connecting post 412. The pin 421 first contacts the retaining bead 414, and during the continuous movement, the external force is applied to the retaining bead 414, causing the retaining bead 414 to move outward. When the retaining groove 422 of the pin 421... When the ball is moved to the side of the retaining bead 414, the retaining bead 414 is inserted into the slot 422 of the pin 421 under the elastic force of the elastic element 418, achieving initial fixation. When the external force applied to the sliding sleeve 43 is released, the spring 415 rebounds, driving the sliding sleeve 43 to slide back to its original position. The pressure sleeve 431 of the sliding sleeve 43 re-presses the retaining bead 414, limiting the retaining bead 414, so that the retaining bead 414 is inserted into the slot 422 and fixed between the retaining bead 414 and the slot 422. At this time, the assembly of the first connector 41 and the second connector 42 is completed.

[0032] When separating the first connector 41 and the second connector 42, apply a certain external force to the sliding sleeve 43. The sliding sleeve 43 slides to avoid the lock ball 414, and then apply a certain external force to the second connector 42 to pull out the pin 421 of the second connector 42.

[0033] When assembling the first connector 41 and the second connector 42, the operation steps are to slide the sliding sleeve 43, insert the pin 421, and finally loosen the sliding sleeve 43. When disassembling the first connector 41 and the second connector 42, the operation steps are to slide the sliding sleeve 43, pull out the pin 421, and finally loosen the sliding sleeve 43. The quick-change component 4 is easy to install and remove, which simplifies the assembly steps between the gimbal 2 and the probe 3. There is no need to repeatedly install and remove screws, and the replacement of the probe 3 is convenient.

[0034] The base 411 has a first mounting plate 416 at one end, and the first mounting plate 416 has multiple sets of first mounting holes 417, which are evenly distributed along the circumference of the first mounting plate 416.

[0035] The first mounting plate 416 of the first connector 41 is fixed to the gimbal 2 by screws, making it easy to install and remove the first connector 41.

[0036] One end of the pin 421 is provided with an arc portion 423 to guide the pin 421 to enter accurately.

[0037] The other end of the pin 421 is provided with a second mounting plate 424, and the second mounting plate 424 has multiple sets of second mounting holes 425, which are evenly distributed along the circumference of the second mounting plate 424.

[0038] The second mounting plate 424 of the second connector 42 is fixed to the housing of the probe head 3 by screws, making it easy to install and remove the second connector 42.

[0039] Working principle: In use, screws are used to install the first connector 41 onto the gimbal 2, and screws are used to install the second connector 42 onto the housing of the probe 3. When installing the probe 3, the second connector 42 of the probe 3 is inserted into the first connector 41 of the gimbal 2, thus achieving a fixed connection between the second connector 42 and the first connector 41, that is, achieving a fixed connection between the gimbal 2 of the UAV 1 and the probe 3. When replacing the probe 3, the corresponding second connector 42 is installed on another set of probe 3 housings. When assembling the first connector 41 and the second connector 42, the operation steps are: slide the sliding sleeve 43, insert the pin 421, and finally loosen the sliding sleeve 43. When separating the first connector 41 and the second connector 42, the operation steps are: slide the sliding sleeve 43, pull out the pin 421, and finally loosen the sliding sleeve 43. This simplifies the assembly steps between the gimbal 2 and the probe 3, eliminating the need for repeated screw installation and removal, and making the replacement of the probe 3 convenient.
