[0013] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0014] Reference Figure 1 and Figure 2 This invention provides a positioning device for a drone after it loses contact, comprising a drone body 1, a positioning device body 2 mounted on the bottom of the drone body 1, and the positioning device body 2 connected to the drone body 1 via an anti-theft assembly module.

[0015] The positioning device body 2 includes a shell 21. The opening of the shell 21 is magnetically connected to a cover plate 22. The shell 21 is made of transparent and light-transmitting material. The controller, collision sensor, GPS / GPRS positioning device, strobe light and buzzer are installed inside the shell 21. The controller is electrically connected to the collision sensor, GPS / GPRS positioning device, strobe light and buzzer. The controller, collision sensor, GPS / GPRS positioning device, strobe light and buzzer are all electrically connected to the power supply in the UAV body 1. The controller, collision sensor, GPS / GPRS positioning device, strobe light and buzzer are all existing technologies of the UAV body 1 and will not be described in detail here.

[0016] After a crash or collision, the collision sensor receives a collision command, the controller transmits the command, the high-decibel buzzer alarm activates, emitting a sharp alarm intermittently, the sound can be clearly heard within 1000 meters; the strobe light illuminates, clearly visible within 500 meters at night; the GPS / GPRS positioning device starts working, sending location information to mobile phones, tablets and other terminals, and the location information is displayed on the APP.

[0017] By installing anti-theft assembly modules, disassembly can be prevented without damage, thus achieving the purpose of theft prevention and avoiding losses to users.

[0018] Reference Figure 1 and Figures 3-6The anti-theft assembly module includes an upper seat 4 fixedly connected to the bottom wall of the drone body 1 and a connecting block 3 fixedly connected to the positioning device body 2. The other side of the connecting block 3 is fixedly connected to a lower seat 5. A stop unit is installed between the upper seat 4 and the lower seat 5. Several inclined walls A41 and several constraint seats 6 that move along the inclined walls A41 are installed on the upper seat 4. The constraint seats 6 and inclined walls A41 are paired with each other. A constraint opening is reserved on the inner surface of the lower seat 5. A drive unit is installed on the lower seat 5. During the process of the upper seat 4 being inserted into the lower seat 5 along orientation A and being securely assembled, the drive unit drives the constraint seats 6 to move along the inclined walls A41 towards orientations B and C. Orientation B is opposite to orientation A, and the angle between orientation C and orientation A is ninety degrees. Orientation C is... Approaching the lower seat 5, the constraint seat 6 moves along direction C into the constraint opening. The upper seat 4 moves along direction B to separate from the lower seat 5. The upper seat 4 and the lower seat 5 are assembled via the stop unit. After the upper seat 4 and the lower seat 5 are assembled, the constraint seat 6 moves one section to the end of the constraint opening with the cooperation of the drive unit. After the upper seat 4 and the lower seat 5 are fastened together via the stop unit, the constraint seat 6 immediately connects with the constraint opening. Through the cooperation of the constraint seat 6, the upper seat 4, and the lower seat 5, a stable fastening structure is formed on the inside. With the cooperation of the stop unit and the constraint seat 6, the upper seat 4 and the lower seat 5 can achieve the purpose of stable assembly, achieve the purpose of anti-unlocking, and thus achieve anti-theft.

[0019] The constraint seat 6 has a pre-installed inclined wall B61. With the cooperation of the drive unit, the constraint seat 6 moves along the inclined wall A41 via the inclined wall B61. Through the cooperation of several inclined walls, the smoothness of the movement of the constraint seat 6 can be enhanced, so that the drive unit can provide a driving force to the constraint seat 6, which can make the constraint seat 6 move along the orientation B and orientation C until it moves into the constraint opening. This reduces the number of driving parts and reduces manufacturing costs.

[0020] The upper seat 4 has reserved openings for movement, the number of which is equal to the number of inclined walls A41. Inclined walls A41 are installed in the corresponding openings. The openings can guide and constrain the movement of the constraint seat 6, ensuring that the constraint seat 6 moves along the inclined walls A41, guaranteeing the accuracy of the movement of the constraint seat 6, and enhancing the stability of the entire structure. A constraint platform 45 is installed at the opening of the opening. The constraint platform 45 constrains the constraint seat 6 to move away from the upper seat 4, and can constrain the constraint seat 6 to prevent it from falling off during the assembly of the upper seat 4 and the lower seat 5, thus enhancing the stability of the constraint seat 6.

[0021] There are two pairs of variable ports, and the two pairs of variable ports are arranged at equal intervals on the peripheral wall of the upper seat 4. There are two pairs of restraint seats 6. Through the variable ports reserved at equal intervals on the peripheral wall of the upper seat 4, the force between the restraint seat 6, the upper seat 4 and the lower seat 5 is evenly transmitted to the upper seat 4 and the lower seat 5, so that the action borne by the upper seat 4 is uniform and the action borne by the lower seat 5 is uniform, enhancing the stability and reliability of the entire structure.

[0022] Refer to Figure 7 , the restraint seat 6 is in a "丄" - shaped structure. The restraint seat 6 includes a variable end 62 and a restraint end 63 that are fixedly connected to each other. The transverse span of the restraint end 63 is smaller than the transverse span of the variable end ⑥2. An inclined wall B61 is reserved on the variable end 62. The restraint platform 45 includes a pair of square platforms arranged on the upper seat 4. The transverse span of the restraint end 63 is smaller than the distance between the pair of square platforms. The transverse span of the variable end 62 is greater than the distance between the pair of square platforms. The pair of square platforms restrain the variable end 62 from crossing over the pair of square platforms, so that the variable end 62 can move between the square platform and the inclined wall A41. The square platform restrains the variable end 62 from crossing over, and the restraint end 63 can pass through the gap between the pair of fixing parts. Then, when the restraint seat 6 moves in the direction B, the restraint end 63 can move to the end of the restraint port.

[0023] The restraint port can include the following two structures: Structure A: The number of restraint ports is equal to the number of restraint seats 6. The restraint ports and the restraint seats 6 are arranged in pairs with each other, and the number of restraint ports is two pairs; <^ Structure B: The restraint port is a circular restraint port 51, which enables the upper seat 4 to be inserted into the lower seat 5 from any direction. The restraint seat 6 can move into the restraint port 51, preventing the upper seat 4 from being adjusted according to the positions of the restraint port and the restraint seat 6 before being inserted into the lower seat 5, ensuring the rapid assembly of the upper seat 4 and the lower seat 5.

[0024] The stop unit can include the following two structures: [[ID=~16]] Structure A: The stop unit includes an insertion port 42 reserved on the upper seat 4 and a stop hook 52 arranged on the lower seat 5. Through the locking structure between the insertion port 42 and the stop hook 52, after the upper seat 4 is inserted into the lower seat 5, only by applying a downward pressing force on the upper end of the upper seat 4, the stop hook 52 can pass through the insertion port 42 in the forward direction to achieve connection. Under the cooperation of the stop hook 52 and the insertion port 42, the stop hook 52 cannot pass through the insertion port 42 in the reverse direction, so that the stop hook 52 and the insertion port 42 cannot be separated, realizing the assembly of the upper seat 4 and the lower seat 5; Structure B: The stop unit includes a buckle block arranged on the upper seat 4 and a hook body arranged on the inner surface of the lower seat 5. Through the buckling structure between the hook body and the buckle block, after the buckle block moves forward to the bottom of the hook body, under the restraint of the hook body, the buckle block cannot move backward to the top of the hook body, so that the buckle block and the hook body cannot be separated, realizing the assembly of the upper seat 4 and the lower seat 5.

[0025] A detachable blocking ring 43 is installed on the upper seat 4. A constraint seat 6 is installed between the blocking ring 43 and the upper seat 4. The blocking ring 43 constrains the constraint seat 6 to move in the direction A. An insert 42 is reserved on the blocking ring 43. The blocking ring 43 and the upper seat 4 are locked together by screws. The blocking ring 43 constrains the constraint seat 6 to prevent the constraint seat 6 from moving in the direction A and separating from the upper seat 4. The installation of the detachable blocking ring 43 not only makes the processing of the upper seat 4 easier and reduces processing costs, but also makes the assembly of the constraint seat 6 easier, facilitating the rapid assembly of the entire structure. A detachable ring 53 is installed on the lower seat 5. A stop hook 52 is installed on the ring 53, which also makes the processing of the lower seat 5 easier and reduces processing costs.

[0026] The drive unit and the stop hook 52 can be two different parts or the same part. In this embodiment, the drive unit and the stop hook 52 are the same part. The upper end of the stop hook 52 passes through the interlocking interface 42 and presses against the constraint seat 6. With the upper seat 4 and the lower seat 5 firmly assembled, the performance of the drive unit is completed through the stop hook 52, which improves the utilization rate of the stop hook 52 and can reduce the number of parts and the area occupied by the entire structure.

[0027] The inner surface of the lower seat 5 has several guide openings 54. A guide platform A55, cooperating with the guide openings 54, is installed on the ring 53. Through the cooperation of the guide openings 54 and the guide platform A55, the assembly speed of the ring 53 and the lower seat 5 is ensured. A guide platform B44, cooperating with the guide openings 54, is installed on the upper seat 4. Through the cooperation of the guide openings 54 and the guide platform B44, the assembly speed of the stop hook 52 and the insertion interface 42, as well as the assembly speed of the upper seat 4 and the lower seat 5, are ensured. There are two pairs of guide openings 54, arranged at equal intervals.

[0028] Reference Figures 8-10 During assembly, first place the constraint seat 6 into the variable opening. The inclined walls B61 and A41 on the constraint seat 6 are aligned, held in place by the blocking ring 43 and secured with screws, thus assembling the upper seat 4 and the constraint seat 6. Following the guide opening 54 and guide platform A55, place the ring 53 into the lower seat 5. Following the guide opening 54 and guide platform B44, insert the upper seat 4 into the lower seat 5 along orientation A, applying pressure to the upper end of the upper seat 4 towards orientation A. The stop hook 52 passes through the insertion interface 42. 2. With the cooperation of the interlocking interface 42, the shape changes and opens towards position C, and the constraint seat 6 is pressed towards position B. The constraint seat 6 moves along the inclined wall A41 towards positions B and C, and moves into the constraint opening to form a snap. The stop hook 52 returns to position C until the stop hook 52 and the interlocking interface 42 are engaged with each other, and the top of the stop hook 52 presses against the constraint seat 6, thus forming an assembly structure that is engaged from the inside. It cannot be disassembled without damage, thereby achieving the purpose of anti-theft.

[0029] The upper seat 4 and the lower seat 5 are assembled via the stop unit. Once the upper seat 4 and the lower seat 5 are assembled and locked via the stop unit, the constraint seat 6 immediately engages with the constraint port. Through the cooperation of the constraint seat 6, the upper seat 4, and the lower seat 5, a solid fastening structure is formed on the inside. With the cooperation of the stop unit and the constraint seat 6, the upper seat 4 and the lower seat 5 can be reliably assembled, which can prevent disassembly without damage and achieve the purpose of theft prevention. Furthermore, the overall structure is relatively simple and requires less processing costs. The variable port can guide and constrain the movement of the constraint seat 6, ensuring that the constraint seat 6 moves along the inclined wall A41, ensuring the accuracy of the constraint seat 6's movement, and enhancing the reliability and stability of the entire structure. The constraint platform 45 can constrain and tighten the constraint seat 6 to prevent it from accidentally falling off during the assembly of the upper seat 4 and the lower seat 5, thus enhancing the stability of the constraint seat 6. The restraint port 51 allows the upper seat 4 to be inserted into the lower seat 5 from any position, and the constraint seat 6 can be moved into the restraint port 51 to prevent the upper seat 4 from having to be inserted into the lower seat 5 according to the following conditions before insertion. The orientation adjustment of the constraint port and constraint seat 6 ensures the assembly speed of the upper seat 4 and the lower seat 5; the installation of the detachable barrier ring 43 not only simplifies the preparation of the upper seat 4 and reduces processing costs, but also simplifies the assembly of the constraint seat 6, thereby increasing the assembly speed of the entire structure; the installation of the detachable ring 53 simplifies the processing of the lower seat 5 and reduces locking processing costs; through the cooperation of the guide port 54, guide table A55 and guide table B44, the assembly speed of the ring 53 and the lower seat 5 can be ensured, the assembly speed of the stop hook 52 and the insertion interface 42 can be increased, and the assembly speed of the upper seat 4 and the lower seat 5 can also be increased.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
