In this embodiment, the quick-release connection hole 411 is substantially in the shape of a four-leaf clover.

[0033] Furthermore, if Figure 4-Figure 5 As shown, the voice component 1 also includes a speaker 12, a voice recognition circuit board 13 and a microphone 14 arranged in the protective shell 11. The speaker 12 and the microphone 14 are electrically connected to the voice recognition circuit board 13. The speaker 12 is used to play sound externally, the microphone 14 is used to pick up external sound, and the voice recognition circuit board 13 is used to recognize and process the sound picked up by the microphone 14.

[0034] Furthermore, if Figure 4-Figure 5 As shown, the protective shell 11 includes a front shell 111 and a rear shell 112 connected to the front shell 111, and the front shell 111 and the rear shell 112 are connected by screws or snap-on. The speaker 12 is installed on the front shell 111, and a plurality of limiting protrusions are arranged circumferentially in the front shell 111. The speaker 12 is fixed within the range formed by the plurality of limiting protrusions. The front side of the front shell 111 is provided with a plurality of sound output holes 1111 for outputting the sound of the speaker 12. The microphone 14 is installed on the voice recognition circuit board 13. The front side and left side of the front shell 111 are provided with pickup holes 1112 corresponding to the positions of the microphone 14. The pickup holes 1112 are provided to facilitate the pickup to pick up external sounds.

[0035] In this embodiment, the voice recognition circuit board 13 is provided with a data interface, and the front shell 111 is provided with an opening for leaking out the data interface to facilitate the connection between an external data line and the data interface.

[0036] Furthermore, if Figure 1-Figure 2As shown, the body shell includes a front shell 41, a middle shell 42 and a rear shell 43. The front shell 41 is connected to the front end of the middle shell 42, and the rear shell 43 is connected to the rear end of the middle shell 42. The bottom of the front shell 41 is provided with a quick-release connection hole 411. In this embodiment, the quick-release connection hole 411 is set on the bottom plate of the front shell 41. When the quick-release connector 5 is installed, the hanging part of the quick-release connector 5 is firstly inserted into the quick-release connection hole 411 so that the first extension part 52 and the second extension part 53 of the quick-release connector 5 are located above the inner side surface of the bottom plate of the front shell 41, and then the quick-release connector 5 is horizontally rotated until the first extension part 52 and the second extension part 53 are rotated to the position where they can abut against the inner side surface of the bottom plate of the front shell 41, and then the first extension part 52 and the second extension part 53 are released. Under the action of gravity, the first extension part 52 and the second extension part 53 contact and abut against the inner side surface of the bottom plate, so that the voice component 1 is suspended on the body shell.

[0037] The advantage of setting the quick-release connection hole 411 on the bottom plate of the front shell 41 is that since the voice component 1 is in a suspended state, the voice component 1 can maintain a relatively stable state when not affected by external forces.

[0038] Preferably, in order to further improve the stability of the voice component 1 after suspension, a first limiting groove and a second limiting groove are provided on the inner side surface of the bottom plate at a position that can abut against the first extension part 52 and the second extension part 53. The first limiting groove is used to limit the first extension part 52, and the second limiting groove is used to limit the second extension part 53. One side of the first limiting groove and the second limiting groove is flush with the side wall of the quick-release connecting hole 411, so that the first limiting groove has a gap that allows the first extension part 52 to enter, and the second limiting groove has a gap that allows the second extension part 53 to enter. When installing the quick-release connector 5, first, insert the hanging part of the quick-release connector 5 into the quick-release connecting hole 411 so that the first extension part 52 and the second extension part 53 of the quick-release connector 5 are located above the inner side of the bottom plate, and then rotate the quick-release connector 5 horizontally until the first extension part 52 corresponds to the position of the first limiting groove, and the second extension part 53 corresponds to the position of the second limiting groove. Then, release the hand, and the first extension part 52 and the second extension part 53 enter the first limiting groove and the second limiting groove respectively under the action of gravity. The first limiting groove and the second limiting groove can limit the first extension part 52 and the second extension part 53 in the horizontal direction, thereby improving the stability of the voice component 1 after suspension.

[0039] Furthermore, if Figure 1-Figure 2As shown, the head structure 2 includes a head shell, and a main control board arranged in the head shell, the main control board is responsible for the overall control of the robot dog, the head shell is connected to the top of the front section shell 41, and the voice recognition circuit board 13 can be connected to the main control board in a wireless or wired manner; the leg structure 3 includes a profiling left front leg 31, a profiling left rear leg 32, a profiling right front leg 33 and a profiling right rear leg 34, the profiling left front leg 31 and the profiling right front leg 33 are respectively connected to the left and right sides of the front section shell 41, and the profiling left rear leg 32 and the profiling right rear leg 34 are respectively connected to the left and right sides of the rear section shell 43. The profiling left front leg 31, the profiling left rear leg 32, the profiling right front leg 33 and the profiling right rear leg 34 are symmetrically arranged in pairs, which improves the stability of the robot dog when walking and makes it less likely to fall.

[0040] Specifically, the left front leg 31, the left rear leg 32, the right front leg 33 and the right rear leg 34 all include hip shoulders, thighs and calves, and they can all be moved by using the configured steering gear.

[0041] In this embodiment, the head shell is in the shape of an inverted quadrangular pyramid, extending from the front to the rear and with a gradually increasing cross-sectional area to imitate the head shape of a reptile. A head bracket is fixedly connected to the head shell by screws. The head bracket is in a square shape with a hollow structure in the middle. The four sides of the head bracket are tightly fitted to the inner wall of the head shell. The hollow structure of the head bracket tends to constitute an installation area for installing the main control board. The back side of the main control board is fixed in the hollow structure of the head bracket. A camera electrically connected to the main control board is installed on the front side of the head shell. The head shell is connected to the top plate of the front shell 41 by a servo configured therefor. When the servo of the head shell works, it drives the head shell to perform horizontal rotation relative to the front shell 41.

[0042] In this embodiment, the rear plate of the rear section shell 43 is provided with a tail structure, and the tail structure includes a tail shell. The tail shell can be fixed or configured with a servo so that it swings relative to the rear section shell 43 under the power of the servo.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
