[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be understood that, in the description of this utility model, unless otherwise expressly specified and limited, the term "plural" means two or more; the terms "first," "second," ... are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated; the terms "installation" and "connection" should be interpreted broadly, for example, "connection" can be a fixed connection, a detachable connection, or an integral connection, and can be a direct connection or an indirect connection through an intermediate medium; the terms "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation or be constructed in a specific orientation.

[0025] See Figure 1 In some embodiments, the disclosed wall-climbing photography robot includes a wall-climbing robot body 10 and a gimbal camera 20 mounted on the wall-climbing robot body 10. The wall-climbing robot body 10 is provided with two drive modules to drive the wall-climbing photography robot to move.

[0026] Combination Figures 2 to 5 As shown, in some embodiments, the drive module 30 includes a mounting base 31, a drive motor (not shown), a drive wheel 32, a driven wheel 33, and a tensioning wheel 34. The drive motor is fixedly mounted on the outer side of the mounting base 31. The drive wheel 32 is rotatably disposed in the mounting base 31 and connected to the shaft of the drive motor to drive the drive wheel 33. The driven wheel 33 is rotatably disposed in the mounting base 31 and connected to the drive wheel 32 via a synchronous belt 35. The tensioning wheel 34 is rotatably disposed in the mounting base 31 and presses down to tension the synchronous belt 35. By using the tensioning wheel 34, during use, the tensioning wheel 34 can press down to tension the synchronous belt 35, increasing the contact area between the synchronous belt 35 and the wall surface, improving the performance stability of the drive module 30, and making it suitable for more complex operating environments.

[0027] In the embodiment shown in the accompanying drawings, the mounting base 31 is designed as a cover-shaped mounting base with an accommodating space 310, comprising a left housing 311 and a right housing 312 detachably assembled to the left housing 311. The mounting base 31 is composed of detachably assembled left and right housings 311 and 312, facilitating the assembly, disassembly, and maintenance of the drive module 30. Connection methods such as screw connections and snap-fit ​​connections can be used to achieve the detachable assembly of the left housing 311 and the right housing 312.

[0028] The drive motor can be fixed to the side of the mounting base 31 using fasteners such as screws. Preferably, the drive motor is a worm gear reducer motor with a power-off self-locking function. When the wall-climbing robot is stationary at a certain point on the wall, the drive module 30 is powered off, and the synchronous belt 35 is pressed against the wall by the wall-climbing robot's adsorption mechanism (e.g., a negative pressure fan). At this time, the power of the adsorption mechanism can be appropriately reduced to increase the usage time of the wall-climbing robot.

[0029] In some preferred embodiments, a first bearing is provided on each side of the driving wheel 32, and the first bearing is fixed to the mounting base 31. A second bearing is provided on each side of the driven wheel 33, and the second bearing is fixed to the mounting base 31. By providing the first bearings and / or the second bearings, the driving wheel 32 and / or the driven wheel 33 are correspondingly limited and protected against friction, thereby reducing friction of the driving wheel 32 and / or the driven wheel 33 during rotation.

[0030] See Figure 4 and Figure 5 A spindle 313 is provided inside the mounting base 31, and the tensioning wheel 34 is sleeved on the spindle 313 to achieve a rotatable configuration. In the embodiment shown in the attached drawings, the spindle 313 and the left housing 311 of the mounting base 31 are integrally molded by a method such as injection molding, and a third bearing 314 is provided on the right housing 312 corresponding to the spindle 313, with the end of the spindle 313 inserted into the third bearing 314. In this way, the spindle 313 is prevented from becoming a cantilever shaft, ensuring the working stability of the tensioning wheel 34.

[0031] In the preferred embodiment shown in the accompanying drawings, the driving pulley 32, driven pulley 33, and tension pulley 34 are toothed pulleys, and the timing belt 35 is a toothed belt. Using a toothed belt in conjunction with toothed pulleys for transmission offers advantages such as good synchronization performance and high load capacity.

[0032] See Figure 3 Preferably, a plurality of recessed patterns 350 are formed at intervals on the outer surface of the synchronous belt 35 along the width direction of the synchronous belt. By setting the patterns 350, the adhesion between the synchronous belt 35 and the wall surface is increased, which can effectively prevent the wall-climbing robot from slipping on harsh environmental walls (such as wet walls).

[0033] like Figure 2 As shown, in some embodiments, the outer side of the mounting base 31 has a plurality of mounting ears 315, and a connecting through hole 3150 is formed in each mounting ear 315. The mounting ears 315 facilitate the mounting of the drive module 30 onto the wall-climbing robot body 10 using fasteners such as screws.

[0034] Figure 6 and Figure 7 The structure of the drive module 30 disclosed in another embodiment is shown, and... Figures 2-5 The difference in the disclosed embodiments lies in the different arrangement of the tensioning wheel 34. Referring to the accompanying drawings, in this embodiment, the tensioning wheel 34 is rotatably mounted on a wheel seat 36. A lifting member 37 is provided above the wheel seat 36 in the mounting base 31. A vertically arranged compression spring 38 is provided between the wheel seat 36 and the lifting member 37, causing the compression spring 38 to press down on the wheel seat 36. In this way, the compression spring 38 generates a downward force on the tensioning wheel 34, ensuring that the tensioning wheel 34 is always in contact with the timing belt 35 to maintain the contact between the timing belt 35 and the wall surface at its maximum.

[0035] exist Figure 6 and Figure 7 In the illustrated embodiment, the wheel seat 36 includes an inverted U-shaped seat 360 and a spindle 361 fixed to the lower parts of both sides of the inverted U-shaped seat 360. A sliding sleeve 362 is formed on the top surface of the inverted U-shaped seat 360, and a sliding rod 370 is formed on the connecting member 37. The sliding rod 370 is slidably inserted into the sliding sleeve 362, and the compression spring 38 is sleeved on the sliding sleeve 362 and the sliding rod 370. The tension wheel 34 is rotatably sleeved on the spindle 361, thereby realizing the setting of the tension wheel 34. The cooperation between the sliding sleeve 362 and the sliding rod 370 can prevent the tension wheel 34 from shaking.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Those skilled in the art can make various equivalent changes and improvements based on the above embodiments. All equivalent changes or modifications made within the scope of the claims should fall within the protection scope of the present utility model.
