[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0029] like Figure 1-4As shown, the mobile vehicle of the embodiment of the utility model includes: a body 1, a mobile component 2, a control unit 3 and a ring array sound collection module 4.

[0030] The body 1 includes a first placement area 11. The moving assembly 2 is arranged at the bottom of the body 1, and the moving assembly 2 includes a driving module, a driving motor and a wheel 21. The driving module is electrically connected to the driving motor, and the driving motor is connected to the wheel 21. The control unit 3 is arranged at the top of the body 1, and the control unit 3 is located above the first placement area 11. The control unit 3 includes a control module, and the control module is electrically connected to the driving module. The annular array sound collection module 4 is connected to the control unit 3, and the annular array sound collection module 4 includes a plurality of sound collection holes 41. The plurality of sound collection holes 41 are arranged on the outer peripheral surface of the annular array sound collection module 4 in an annular interval arrangement, and the annular array sound collection module 4 is electrically connected to the control module.

[0031] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the first placement area 11 is used to place the suitcase 100. The moving component 2 is connected to the bottom of the body 1, and the driving module is used to send instructions to the driving motor so as to control the wheels 21 to run or stop through the driving motor. The control unit 3 is arranged above the first placement area 11 to avoid the luggage 100 placed in the first placement area 11 from blocking the control unit 3, which is conducive to the ring array sound collection module 4 on the control unit 3 to collect sound. Multiple sound collection holes 41 are arranged at intervals along the circumference of the ring array sound collection module 4, which facilitates the ring array sound collection module 4 to collect sound information from different directions, further improving the accuracy of sound information collection.

[0032] It can be understood that after the annular array sound collection module 4 collects sound information, it can be transmitted to the control module, the control module can receive the sound information and process it, and after processing the sound information, the control module can transmit the processed information to the drive module so as to control the drive motor through the drive module, thereby controlling the operation or stop of the wheel 21.

[0033] Among them, the annular array sound collection module 4 includes a sound collection module, a sound recognition module, a direction recognition module and an audio signal processing module, so that the annular array sound collection module 4 can be used to perform sound recognition, collection, processing and transmission functions.

[0034] That is to say, the mobile carrier of the embodiment of the utility model places the control unit 3 above the first placement area 11, which avoids objects on the mobile carrier from blocking the control unit 3, thereby facilitating the annular array sound collection module 4 on the control unit 3 to collect sound information.

[0035] Therefore, the mobile vehicle of the embodiment of the utility model can prevent objects such as luggage from blocking the circular array sound collection module, and has the advantage of facilitating the collection of sound information.

[0036] It should be noted that a power source is also provided on one of the body 1 and the mobile assembly 2 to provide power to the electric devices such as the drive motor, the control module and the drive module. Of course, the power source can be a rechargeable power source or a detachable power source.

[0037] The mobile component 2 may also be provided with an obstacle avoidance sensor and an automatic obstacle avoidance drive controller, etc. The obstacle avoidance sensor is electrically connected to the automatic obstacle avoidance drive controller, and the automatic obstacle avoidance drive controller is electrically connected to the drive module. When in use, the obstacle avoidance sensor detects and obtains detection information, and transmits the detection information to the automatic obstacle avoidance drive controller, which then controls the drive motor through the drive controller to realize the automatic avoidance function.

[0038] In some embodiments, Figure 1 and Figure 2 As shown, the number of the sound collecting holes 41 is not less than four, and at least two of the sound collecting holes 41 are arranged along the first direction (such as Figure 1 The front-to-back direction in the figure) is relatively arranged, and at least two sound collecting holes 41 are arranged along the second direction (such as Figure 1 The first direction is perpendicular to the second direction, and the first direction and the second direction are both perpendicular to the height direction of the body 1 (such as Figure 1 The up and down directions in the image are vertical.

[0039] For example, there are four sound collecting holes 41, two of which are arranged opposite to each other in the left-right direction, and the other two are arranged opposite to each other in the front-back direction, which is conducive to collecting sound information from different directions.

[0040] Preferably, if Figure 1 As shown, there are eight sound collection holes 41, and the eight sound collection holes 41 are evenly spaced along the circumference of the annular array sound collection module 4, which is further conducive to collecting sound information from different directions.

[0041] In some embodiments, Figure 1 and 2 As shown, the body 1 includes a first placement table 12, a connecting section 13 and a second placement table 14, the moving component 2 is connected to the first placement table 12, the first placement table 12 and the second placement table 14 are arranged opposite to each other in the up and down directions, the connecting section 13 is connected between the first placement table 12 and the second placement table 14, the first placement table 12, the second placement table 14 and the connecting section 13 define a first placement area 11, and the control unit 3 is connected to the second placement table 14.

[0042] Specifically, Figure 1 As shown, the first placement platform 12 is located below the second placement platform 14, the lower end of the connecting section 13 is connected to the first placement platform 12, the upper end of the connecting section 13 is connected to the second placement platform 14, and the control unit 3 is connected to the second placement platform 14 and located above the second placement platform 14. The upper surface of the first placement platform 12, the wall surface of the connecting section 13, and the lower surface of the second placement platform 14 define the first placement area 11.

[0043] In some embodiments, Figure 1 and Figure 2 As shown, the first placement platform 12 includes a first placement surface 121 and a first annular enclosure 122 . The first placement surface 121 is disposed on a side of the first placement platform 12 adjacent to the second placement platform 14 , and the first annular enclosure 122 surrounds the first placement surface 121 .

[0044] It can be understood that the upper surface of the first placement platform 12 is the first placement surface 121, and the first annular enclosure 122 is arranged around the first placement surface 121, which can be used to block the suitcase 100 placed in the first placement area 11 to prevent the mobile vehicle of the embodiment of the utility model from shaking, causing the suitcase 100 to leave the first placement area 11, thereby improving the safety of the mobile vehicle of the embodiment of the utility model.

[0045] In some embodiments, the first placement surface 121 is a slope whose height gradually increases in a direction away from the connecting section 13 .

[0046] It is understandable that if Figure 1 , Figure 3 and Figure 4 As shown, the height of the first placement surface 121 gradually decreases from the front to the back, so when the suitcase 100 is placed in the first placement area 11, the suitcase 100 is in an inclined state close to the connecting section 13. In other words, when the suitcase 100 or other objects are placed on the first placement surface 121, the suitcase 100 or other objects can lean against the connecting section 13, thereby forming a more stable state, further improving the safety of the mobile vehicle of the embodiment of the utility model.

[0047] In some embodiments, Figure 1-Figure 3 As shown, the second placement platform 14 includes a second placement surface 141 and a second annular enclosure 142 . The second placement surface 141 is arranged on a side of the second placement platform 14 away from the first placement platform 12 , and the second annular enclosure 142 surrounds the second placement surface 141 .

[0048] Specifically, the upper surface of the second placement platform 14 is a second placement surface 141, and the second placement surface 141 is parallel to the horizontal plane so as to place other objects. The second annular enclosure plate 142 is arranged around the second placement surface 141, and can be used to block objects placed on the second placement surface 141 to prevent the objects placed on the second placement surface 141 from falling.

[0049] In some embodiments, Figure 1 and Figure 3 As shown, the second placement platform 14 also includes a placement plate 15, which is connected to the second annular enclosure 142. The placement plate 15, the second placement surface 141 and the second annular enclosure 142 define a second placement area 17. The control unit 3 is connected to the placement plate 15, and the control unit 3 is located above the placement plate 15.

[0050] Specifically, Figure 1 As shown, the lower end of the placement plate 15 is connected to the second annular enclosure 142, and the front wall of the placement plate 15 can be used to place smart products such as a tablet computer 300. The rear wall of the placement plate 15, the second annular enclosure 142 and the second placement surface 141 define a second placement area for placing other objects, thereby increasing the storage space of the mobile vehicle of the embodiment of the utility model.

[0051] In addition, the second placement platform 14 further includes a reinforcing plate 16 and an extension plate, wherein the reinforcing plate 16 is connected between the second annular enclosure plate 142 and the placement plate 15, and the extension plate is connected to the upper end of the placement plate 15 and is located above the second placement area 17. Specifically, Figure 1 As shown, there are two reinforcing plates 16, which are respectively arranged on the left and right sides of the placement plate 15, thereby improving the connection strength of the placement plate 15. The control part 3 is arranged on the upper surface of the extension plate to prevent the objects placed in the second placement area 17 from blocking the control part 3.

[0052] Optionally, the angle between the placement plate 15 and the second placement surface 141 is greater than 0 degrees and less than or equal to 90 degrees. Figure 1 As shown, the angle between the placement plate 15 and the second placement surface 141 can be set according to different operating positions. For example, when the operator needs to operate in front of the mobile vehicle, the upper end of the placement plate 15 is tilted backward; or, when the operator needs to operate at the rear of the mobile vehicle, the upper end of the placement plate 15 is tilted forward to facilitate the operator's operation.

[0053] Preferably, the angle between the placement plate 15 and the second placement surface 141 is greater than or equal to 30 degrees and less than or equal to 60 degrees.

[0054] It should be noted that the surface of the placement board 15 is provided with an anti-slip pad, so that the tablet computer 300 can be placed directly on the placement board 15, or the surface of the placement board 15 is provided with a protrusion, when the tablet computer 300 is placed, the tablet computer 300 can be in contact with the protrusion to ensure the stability of the tablet computer 300.

[0055] In some embodiments, Figure 1 and Figure 2 As shown, the control part 3 also includes a first surface 31 and a second surface 32. The first surface 31 and the second surface 32 are arranged at the upper end of the control part 3. The first surface 31 and the second surface 32 intersect with each other. The first surface 31 and the second surface 32 form a V-shaped groove opening upward, and the angle between the first surface 31 and the second surface 32 is greater than 80 degrees and less than 100 degrees.

[0056] It is understandable that the area of ​​the first surface 31 is larger than that of the second surface 32 , the first surface 31 is used to place objects such as the mobile phone 200 , and the second surface 32 is used to block the mobile phone placed on the first surface 31 to prevent the mobile phone 200 from sliding off.

[0057] Preferably, the angle between the first surface 31 and the second surface 32 is equal to 90 degrees, and the angle between the first surface 31 and the horizontal plane is greater than 0 degrees and less than 45 degrees. In other words, the angle between the first surface 31 and the horizontal plane is smaller than the angle between the second surface 32 and the horizontal plane, so that the inclination angle of objects such as the mobile phone 200 placed on the first surface 31 is smaller, making the placed objects more stable.

[0058] In some embodiments, the control unit 3 also includes a first baffle 33 and a second baffle 34, the extension direction of the V-shaped groove is consistent with the second direction, the first baffle 33 and the second baffle 34 are both connected between the first surface 31 and the second surface 32, the first baffle 33 and the second baffle 34 are relatively arranged along the extension direction of the V-shaped groove, and at least part of the first surface 31, the second surface 32, the first baffle 33 and the second baffle 34 define a third placement area 311.

[0059] Specifically, Figure 1 As shown, the V-shaped groove extends in the left-right direction, the first baffle 31 is arranged on the left side of the V-shaped groove, and the second baffle 32 is arranged on the right side of the V-shaped groove. The first surface 31 can be used to completely define the third placement area 311; or Figure 3 As shown, a portion of the first surface 31 may be used to define a third placement area 311 .

[0060] Preferably, a portion of the first surface 31 is used to define the third placement area 311, that is, another portion of the first surface 31 (the portion of the first surface 31 away from the second surface) extends outward from the third placement area 311, thereby increasing the area for placing the mobile phone 200, which is conducive to placing objects of different sizes.

[0061] In addition, a wireless charging component may be provided on the control unit 3 so as to wirelessly charge a device such as a mobile phone 200 with a wireless charging function placed in the third placement area 31 .
