[0042] In some embodiments, Figure 1 This is a schematic diagram of the structure of a PTZ camera. Figure 1 , Figure 1 The housing 101 of the pan-tilt camera shown in the figure has an interlayer for accommodating the cable 102. After passing through the interlayer, the cable 102 in the housing 101 enters the base 103 through the connection between the housing 101 and the base 103. Since the interlayer for the cable 102 to pass through the base 103 is formed on the housing 101 of the pan-tilt camera, the overall size of the pan-tilt camera is large, and the disassembly is complicated, which increases the production cost and after-sales cost of the pan-tilt camera.

[0043] refer to Figure 2 , Figure 2 is a cross-sectional view of a pan / tilt camera at a first viewing angle according to an exemplary embodiment; Figure 3 is a schematic structural diagram of a pan / tilt camera at a second viewing angle according to an exemplary embodiment; Figure 4 is an exploded diagram of a pan-tilt camera according to an exemplary embodiment; Figures 2 to 4 , the pan-tilt camera provided in the embodiment of the present disclosure is introduced.

[0044] In some embodiments, Figures 2 to 4 As shown, the embodiment of the present disclosure provides a pan-tilt camera, comprising:

[0045] The base 11 forms a receiving cavity with a first opening 111;

[0046] The camera module comprises an outer shell 12 and a camera body 13;

[0047] The camera body 13 is disposed in the housing and can move relative to the housing 12 to reveal or conceal the camera 131 of the camera body 13;

[0048] The outer shell 12 is partially disposed at the first opening 111 and is movable relative to the base 11; wherein the outer shell 12 is formed with a first threading hole 121 at an edge close to the first opening 111;

[0049] One end of the power line 14 is connected to the camera body 13 , and the other end passes through the first threading hole 121 and the first opening 111 , and is connected to the power board 15 in the accommodating cavity.

[0050] It can be understood that the above-mentioned pan-tilt camera includes a base 11 and a camera module, wherein the base 11 is used to support the camera module. A receiving cavity having a first opening 111 is formed on the base 11, and the camera module can be arranged at one end of the base 11 close to the first opening 111. The camera module includes an outer shell 12 and a camera body 13. When the camera module is arranged at one end of the base 11 close to the first opening 111, part of the outer shell 12 can extend from the first opening 111 into the receiving cavity of the base 11, and the outer shell 12 can rotate in a first direction relative to the base 11 to adjust the lens orientation of the camera 131 included in the camera body 13, wherein the first direction is a direction parallel to the plane where the first opening 111 is located.

[0051] In addition, a first threading hole 121 is formed at the edge of the outer shell 12 near the first opening 111. The pan-tilt camera also includes a power board 15 and a power cord 14. The power board 15 is located in the accommodating cavity of the base 11. One end of the power cord 14 is connected to the camera body 13, and the other end passes through the outer shell 12 from the first threading hole 121 and is connected to the power board 15 located in the accommodating cavity.

[0052] In some embodiments, the shape and size of the base 11 can be designed as needed, and the embodiments of the present disclosure are not limited to this.

[0053] Exemplarily, the base 11 may be shaped like a hollow cylinder with one opening, wherein the one opening on the cylinder is the first opening 111 on the base 11. Alternatively, the base 11 may be shaped like a hollow truncated cone with one opening, in which case the opening on the truncated cone is the first opening 111 of the base 11.

[0054] In some embodiments, the base 11 can be made of any material with a certain hardness and strength, which is not limited in the embodiments of the present disclosure.

[0055] Exemplarily, the base 11 may be made of plastic or alloy material having a certain hardness and strength.

[0056] In some embodiments, the entire base 11 may be an integral structure, that is, formed by casting plastic or alloy material at one time.

[0057] In some embodiments, the shape and size of the outer shell 12 can also be designed as needed, which is not limited in the embodiments of the present disclosure.

[0058] Exemplarily, the shape of the outer shell 12 can be designed according to the shape of the first opening 111, and the size of the outer shell 12 can be designed according to the size of the first opening 111. For example, when the first opening 111 is circular, the outer shell 12 can be a hollow sphere, and the maximum size of the outer shell 12 in the first direction is greater than or equal to the maximum size of the first opening 111, so that at least part of the outer shell 12 can be exposed outside the accommodating cavity of the base 11 through the first opening 111.

[0059] In some embodiments, the outer shell 12 may also be made of any material having a certain hardness and strength, and the embodiments of the present disclosure are not limited to this.

[0060] In some embodiments, the outer shell 12 may be an integral structure or a split structure, which is not limited in the embodiments of the present disclosure.

[0061] In some embodiments, the outer shell 12 may be in the shape of a hollow sphere. Based on this, the maximum dimension of the outer shell 12 in the first direction may be the diameter of the sphere.

[0062] In some embodiments, a second opening 122 is also formed on the outer shell 12, and the camera body 13 located in the outer shell 12 can move in a first direction or a second direction relative to the outer shell 12 to reveal or hide a camera 131 included in the camera body 13 through the second opening 122, wherein the second direction is a direction perpendicular to the direction where the first plane is located.

[0063] In some embodiments, the size of the second opening is larger than the lens size of the camera 131. When the camera 131 is exposed through the second opening 122 and the center of the lens of the camera 131 is close to or coincides with the center of the second opening 122, the direction of the camera 131 is parallel to the plane where the first opening 111 is located.

[0064] In some embodiments, a heat dissipation hole 123 may be further formed on the outer shell 12. When the camera 131 is exposed through the second opening 122, the lens of the camera 131 faces an end away from the heat dissipation hole 123.

[0065] In some embodiments, the camera body 13 may include one or more cameras 131 . When the camera body 13 includes multiple cameras, all of the multiple cameras 131 may be exposed through the second opening 122 or exposed in sequence.

[0066] In some embodiments, the camera body 13 may further include a circuit board 132, on which there is a circuit for controlling the working process of the camera 131. Based on this, the power line 14 connected to the camera body 13 may be connected to the circuit board 132.

[0067] In some embodiments, the PTZ camera further includes: an inner shell 16, which is located inside the outer shell 12, and the size of the inner shell 16 is larger than the size of the second opening 122. The inner shell 16 has a third opening 161, the camera body 13 or the camera 131 is connected to the inner shell 16, and the lens of the camera 131 can be exposed through the third opening 161. Based on this, when the camera body 13 and the inner shell 16 rotate relative to the outer shell 12, the inner shell 16 can always cover the second opening 122. When the distance between the center of the third opening 161 on the inner shell 16 and the center of the second opening 122 on the outer shell 12 is less than the first preset distance, the mirror image exposed through the third opening 161 is also exposed through the second opening 122 at the same time. When the distance between the center of the third opening 161 on the inner shell 16 and the center of the second opening 122 on the outer shell 12 is greater than or equal to the first preset distance, the outer shell 12 can shield the camera 131, that is, the camera 131 is hidden in the outer shell 12.

[0068] In some embodiments, the outer wall of the inner shell 16 may fit with the inner wall of the outer shell 12. For example, when the outer shell 12 is a spherical shell, the outer wall of one end of the inner shell 16 close to the outer shell 12 may be an arc surface that fits with the inner wall of the outer shell 12.

[0069] In some embodiments, the first threading hole 121 can be formed on the outer shell 12 located in the accommodating cavity and close to the edge of the first opening 111. Based on this, the power cord 14 can directly enter the accommodating cavity of the base 11 after passing through the outer shell 12 from the first threading hole 121, and will not be exposed outside the base 11, which can increase the overall aesthetics of the pan-tilt camera.

[0070] In some embodiments, the size of the first threading hole 121 can be set as needed, for example, according to the number and thickness of the power cords 14, which is not limited in the embodiments of the present disclosure.

[0071] In some embodiments, the first threading hole 121 can be formed at the edge of the outer shell 12 away from the second opening 122 and close to the first opening 111. Since the camera 131 needs to be exposed through the second opening 122, the range of movement of the camera body 13 will be located in the accommodation space of the outer shell 12 close to the second opening 122. The first threading hole 121 is formed on the side away from the second opening 122, which can reduce the interference of the power cord 14 passing through the first threading hole 121 on the movement of the camera body 13 in the outer shell 12.

[0072] In the embodiment of the present disclosure, a first threading hole 121 is formed on the edge of the outer shell 12 near the first opening 111, and the power cord 14 is introduced into the accommodating cavity of the base 11 through the first threading hole 121 to be connected to the power board 15. Compared with forming an interlayer on the outer shell 12 to introduce the power cord 14 from the outer shell 12 into the base 11, not only the size of the outer shell 12 can be reduced, but also the production complexity and disassembly complexity of the pan-tilt camera can be reduced.

[0073] In some embodiments, the outer shell 12 includes a first partial shell 124 and a second partial shell 125 connected to the first partial shell 124;

[0074] The first housing portion 124 is formed with a second opening 122 , and the camera body 13 can move in the accommodation space surrounded by the first housing portion 124 , and the camera 131 is exposed through the second opening 122 ; the first threading hole 121 is formed at the edge of the second housing portion 125 close to the first opening 111 .

[0075] In some embodiments, when the outer shell 12 is composed of the first partial shell 124 and the second partial shell 125 , a plane formed by the connection between the first partial shell 124 and the second partial shell 125 is perpendicular to the plane where the first opening 111 is located.

[0076] In some embodiments, the first partial shell 124 and the second partial shell 125 are detachably connected, which can facilitate maintenance of the camera body 13 located in the outer shell 12.

[0077] Exemplarily, the second partial shell 125 and the second partial shell 125 can be connected by a fixing member to form the outer shell 12, or the first partial shell 124 and the second partial shell 125 can be bonded by an adhesive to form the outer shell 12. The embodiment of the present disclosure does not limit the connection method of the first partial shell 124 and the second partial shell 125.

[0078] In some embodiments, the second opening 122 is formed at an end of the first partial housing 124 away from the second partial housing 125 , and the second opening 122 is oriented in a direction parallel to the plane where the first opening 111 is located.

[0079] In some embodiments, reference Figure 2 , the first partial shell 124 and the second partial shell 125 can both be hemispherical.

[0080] In the embodiment of the present disclosure, since the camera body 13 moves within the accommodating space enclosed by the first partial shell 124, and the first threading hole 121 is formed at the edge of the second partial shell 125 close to the first opening 111, the first threading hole 121 can be located outside the moving range of the camera body 13, further reducing the interference of the power cord 14 passing through the first threading hole 121 with the movement process of the camera body 13.

[0081] In some embodiments, the first threading hole 121 may be formed at an edge of the second housing portion 125 away from the first housing portion 124 and close to the first opening 111. Exemplarily, the first threading hole 121 may be formed on the second housing portion 125 that has the greatest distance from the second opening 122. Based on this, the power cord 14 passing through the first threading hole 121 may have a greater distance from the camera body, which may further reduce the interference of the power cord 14 with the activity of the camera body 13.

[0082] In some embodiments, a difference between a size of the first opening 111 in the first direction and a size of the outer shell 12 in the first direction is less than a preset difference, and the first direction is a direction parallel to the plane where the first opening 111 is located.

[0083] In some embodiments, the size of the outer shell 12 in the first direction may be the maximum size of the outer shell 12 in the first direction. That is, the difference between the size of the first opening 111 in the first direction and the maximum size of the outer shell 12 in the first direction is less than the preset difference. The preset difference can be set as needed, and the embodiments of the present disclosure are not limited thereto.

[0084] In the embodiment of the present disclosure, when the outer shell is spherical, since part of the outer shell 12 can enter the accommodation cavity of the base 11 through the first opening 111, the smaller the difference between the size of the first opening 111 and the size of the outer shell 12 in the first direction, the more the shell part of the outer shell 12 extends into the accommodation cavity, and the farther the distance between the first threading hole 121 and the second opening 122 in the first direction provided on the edge of the outer shell 12 close to the first opening 111 is. Since the camera 131 needs to be exposed through the second opening 122, the range of movement of the camera body 13 will be located in the accommodation space of the outer shell 12 close to the second opening 122, and the farther the distance between the first threading hole 121 and the second opening 122 in the first direction is, the less interference the power cord 14 located in the first threading hole 121 will have on the activity process of the camera body.

[0085] In some embodiments, the pan-tilt camera further comprises:

[0086] The movable connecting plate 17 is disposed in the accommodating cavity and connected to the outer shell 12, and can drive the outer shell 12 to move;

[0087] The movable connecting plate 17 is formed with a second threading hole 171 , and the second threading hole 171 is used for the power cord 14 to pass through.

[0088] It can be understood that a movable connecting plate 17 is also provided in the receiving cavity of the base 11. The part of the outer shell 12 extending from the first opening 111 into the receiving cavity is connected to the movable connecting plate 17. Based on this, when the movable connecting plate 17 rotates relative to the base 11, the outer shell 12 can be driven to rotate in the first direction relative to the base 11. In addition, a second threading hole 171 is formed on the movable connecting plate 17 for allowing the power cord 14 entering the receiving cavity of the base 11 to pass through.

[0089] In some embodiments, the shape of the movable connecting plate 17 can be set according to the shape of the cross section of the accommodating cavity, and the size of the movable connecting plate 17 in the first direction can be smaller than the size of the accommodating cavity in the first direction. For example, when the accommodating cavity of the base 11 is cylindrical or truncated cone-shaped, the movable connecting plate 17 can be a circular plate with a certain thickness, and the diameter of the circular plate is smaller than the diameter of the cross section of the accommodating cavity.

[0090] In some embodiments, a driving module may be further provided in the accommodating cavity, and a power output end of the driving module is connected to a side of the movable connecting plate 17 away from the outer shell 12. Based on this, the driving module may drive the movable connecting plate 17 to rotate in the first direction, thereby driving the outer shell 12 and the camera body 13 located in the outer shell 12 to rotate in the first direction.

[0091] Exemplarily, the driving module disposed in the accommodating cavity may be any driving module capable of driving the movable connecting plate 17 to move relative to the base 11, such as a motor. The embodiment of the present disclosure does not limit the specific type of the driving module.

[0092] In some embodiments, the movable connecting plate 17 can be made of any material with a certain strength and hardness, which is not limited in the embodiments of the present disclosure.

[0093] Exemplarily, the material for making the movable connecting plate 17 may be Polyoxymethylene (Polyformaldehyde, POM) polyoxymethylene resin.

[0094] In the disclosed embodiment, a movable connecting plate 17 is provided in the accommodating cavity of the base 11, and the outer shell 12 is driven to rotate by the movable connecting plate 17. Compared with driving the outer shell 12 to rotate by a metal shaft, the production cost of the pan-tilt camera can be reduced.

[0095] In some embodiments, the second threading hole 171 may be formed near the center of the movable connecting plate 17. For example, when the movable connecting plate 17 is circular, the second threading hole 171 may be formed near the center of the movable connecting plate 17.

[0096] In some embodiments, the second threading hole 171 may be a through hole opened along the thickness direction of the movable connecting plate 17. The size and shape of the second threading hole 171 may be determined according to the thickness and number of the power cords 14 to be passed through.

[0097] In some embodiments, the first motor 18 is connected to the outer shell 12 at opposite sides of the movable connecting plate 17 and can drive the movable connecting plate 17 to move;

[0098] The second threading hole 171 is disposed near the connection between the first motor 18 and the movable connecting plate 17 .

[0099] In some embodiments, the first motor 18 can be disposed in the accommodating cavity of the base 11, the stator of the first motor 18 is fixed on the base 11, and the rotor of the first motor 18 is connected to the side of the movable connecting plate 17 away from the outer shell 12, and is connected to the center of the movable connecting plate 17. Based on this, when the first motor 18 is working, the rotor of the first motor 18 rotates relative to the stator of the first motor 18, driving the movable connecting plate 17 to rotate relative to the base 11, and then driving the outer shell 12 and the camera body 13 located in the outer shell 12 to rotate in the first direction.

[0100] Exemplarily, when the movable connecting plate 17 is a circular plate and the rotor of the first motor 18 is connected to the movable connecting plate 17, the central axis of the rotor of the first motor 18 coincides with the center of the movable connecting plate 17, or the distance between the central axis of the rotor of the first motor 18 and the center of the movable connecting plate 17 is less than the second preset distance.

[0101] In some embodiments, the model of the first motor 18 can be selected as needed, and the embodiments of the present disclosure are not limited to this.

[0102] In some embodiments, when the first motor 18 is connected to the movable connecting plate 17 via the rotor, a second threading hole 171 may be formed near the connection between the rotor of the first motor 18 and the movable connecting plate 17 .

[0103] In some embodiments, the second threading hole 171 may be a through hole formed near the connection between the movable connecting plate 17 and the rotor of the first motor 18 .

[0104] In the embodiment of the present disclosure, since the rotor of the first motor 18 is connected to the center of the movable connecting plate 17, the second threading hole 171 is formed near the connection between the movable connecting plate 17 and the rotor of the first motor 18. In this way, the power cord 14 located in the base 11 can be confined to a position close to the first motor 18, thereby reducing the amount of winding of the power cord 14 on the first motor 18 when the outer shell 12 rotates in a first direction relative to the base 11, and can also shorten the wiring length of the power cord 14 in the base 11.

[0105] In some embodiments, the movable connecting plate 17 includes: a connecting plate body and a first protrusion formed by extending the connecting plate body to the side away from the outer shell 12, a first through hole is formed in the thickness direction of the connecting plate body, and a second through hole connected to the first through hole is formed on the first protrusion, and the first through hole and the second through hole together form a second threading hole 171.

[0106] In some embodiments, the first through hole is formed near the connection between the movable connecting plate 17 and the first motor 18 .

[0107] In some embodiments, the first protrusion formed on the connecting plate body may be a cylindrical protrusion, and a second through hole is formed in the length direction of the cylindrical protrusion, and the second through hole is connected to the first through hole to form a second threading hole 171.

[0108] In some embodiments, the free end of the first protrusion formed on the connecting plate body can extend to a position close to the power board 15. Since the connecting wire passing through the second threading hole 171 will be connected to the power board 15, extending the free end of the protrusion formed on the connecting plate body to a position close to the power board 15 can also facilitate connecting the power line 14 to the power board 15.

[0109] In some embodiments, the connecting plate body and the first protrusion included in the movable connecting plate 17 may be an integral structure or a separate structure, which is not limited in the embodiments of the present disclosure.

[0110] In some embodiments, the base 11 includes a bottom plate 112 and a side plate 113 , and the bottom plate 112 and the side plate 113 are connected to form a receiving cavity;

[0111] The first motor 18 includes a first stator 181 and a first rotor 182 . The first stator 181 rotates relative to the first rotor 182 . The first rotor 182 is fixed on the bottom plate 112 . The first stator 181 is connected to the movable connecting plate 17 .

[0112] In some embodiments, the base 11 is formed by a bottom plate 112 and a side plate 113 surrounding the bottom plate 112. The accommodation space formed by the bottom plate 112 and the side plate 113 is the accommodation cavity of the base 11. The opening at one end of the side plate 113 away from the bottom plate 112 is the first opening 111 on the base 11. In the case where the first motor 18 includes a first rotor 182 and a first stator 181, the first rotor 182 can also be fixed on the bottom plate 112, and the first stator 181 can be connected to the movable connecting plate 17. Based on this. When the first motor 18 is working, the first rotor 182 is fixed, and the first stator 181 rotates relative to the first rotor 182, driving the movable connecting plate 17 to rotate relative to the side plate 113, thereby driving the outer shell 12 and the camera body 13 located in the outer shell 12 to rotate in the first direction.

[0113] In some embodiments, the model of the first motor 18 can be selected as needed, and the embodiments of the present disclosure are not limited to this.

[0114] In some embodiments, the center of the bottom plate 112 protrudes toward the first opening 111 to form a second protrusion, and the center of the second protrusion is recessed toward the bottom plate 112 to form a second groove. The rotor of the first motor 18 can be fixed in the second groove.

[0115] In the embodiment of the present disclosure, a second groove is formed on the bottom plate 112 , and the rotor of the first motor 18 is fixed in the second groove, which can improve the fixing stability of the first motor 18 on the bottom plate 112 .

[0116] In some embodiments, the bottom plate may also be Figure 4 The circular shape shown.

[0117] In some embodiments, when the base 11 is cylindrical, the side plate 113 may be a cylinder with openings at both ends, and the opening at one end is covered by the bottom plate 112 .

[0118] In some embodiments, the side panel 113 may further include a first side panel portion and a second side panel portion, the first side panel portion and the second side panel portion together form a cylindrical side panel 113, and the first side panel portion and the second side panel portion are detachably connected.

[0119] In some embodiments, the edge of the bottom plate 112 extends in a direction perpendicular to the bottom plate 112 to form a third protrusion, and a thickness of the side plate 113 is recessed toward the inside of the side plate 113 to form a third groove. By inserting the protrusion on the bottom plate 112 into the third groove on the side plate 113, the bottom plate 112 and the side plate 113 can be assembled to obtain the base 11.

[0120] In some embodiments, the power board 15 can be fixed on the inner wall of the side plate 113 near one end of the bottom plate 112. Based on this, one end of the power line 14 is connected to the circuit board 132, and the other end passes through the first threading hole 121 and the second threading hole 171, and is connected to the power board 15 fixed on the inner wall of the side plate 113.

[0121] In some embodiments, a mounting hole may be further provided on the side of the bottom plate 112 facing away from the side plate 113 for fixed installation of the pan / tilt camera in the application site.

[0122] In some embodiments, the inner wall of the side plate 113 is recessed in a direction away from the accommodating cavity to form a first groove, and the edge of the movable connecting plate 17 is located in the first groove and can move relative to the side plate 113 .

[0123] In some embodiments, when the side plate 113 is cylindrical, the first groove on the inner wall of the side plate 113 is an annular groove, and the depth of the first groove is less than the thickness of the side plate 113, and the size of the opening of the first groove in the second direction is greater than the thickness of the movable connecting plate 17. Based on this, the edge of the movable connecting plate 17 can extend into the first groove.

[0124] In other embodiments, when the base 11 is an integrated structure, the first groove may be formed by an inner side wall of the base 11 being recessed toward a side away from the accommodating cavity.

[0125] In the embodiment of the present disclosure, a first groove is formed on the inner wall of the side plate 113, so that the edge of the movable connecting plate 17 can extend into the first groove and can rotate relative to the side plate 113. Based on this, when the movable connecting plate 17 rotates, the two side walls of the first groove can limit the range of motion of the movable connecting plate 17 in the second direction, which can reduce the swing range of the movable connecting plate 17 in the second direction, and further reduce the swing range of the outer shell 12 and the camera body 13 located in the outer shell 12 in the second direction.

[0126] In some embodiments, support ribs 126 are formed on the outer shell 12;

[0127] The inner wall of the side plate 113 close to the first opening 111 protrudes into the accommodating cavity to form a boss 114 , and the boss 114 abuts against the supporting rib 126 to prevent the outer shell 12 from moving towards the bottom plate 112 .

[0128] It can be understood that the end of the outer shell 12 close to the base 11 also has a support rib 126 extending in the direction away from the outer shell 12. The inner wall of the side plate 113 close to the first opening 111 protrudes into the accommodating cavity to form a boss 114. When part of the outer shell 12 extends from the first opening 111 into the accommodating cavity of the base 11, the support rib 126 on the outer shell 12 abuts against the boss 114 on the side plate 113, which can prevent the outer shell 12 from moving in the direction close to the bottom plate 112.

[0129] In some embodiments, the boss 114 is closer to the first opening 111 than the first groove, and the boss 114 may be a sidewall of the first groove.

[0130] In some embodiments, the first threading hole 121 may be formed at a position of the outer shell 12 close to the supporting rib 126 .

[0131] Exemplarily, when the support rib 126 on the outer shell 12 abuts against the boss 114 on the side plate 113, the first side surface of the support rib 126 fits against the inner wall of the side plate 113, and the first threading hole 121 is formed at the connection between the outer shell 12 and the second side surface of the support rib 126. The first side surface and the second side surface are two opposite back surfaces of the support rib 126 in the first direction.

[0132] In some embodiments, reference Figure 2 The support rib 126 can be a wedge-shaped structure, and the end faces of both ends of the support rib 126 are arc-shaped surfaces. The arc-shaped surface at the thicker end of the support rib 126 is fixedly connected with the outer wall of the outer shell 12, and the arc-shaped surface at the thinner end of the support rib 126 abuts against the boss 114 on the side plate 113.

[0133] In some embodiments, when the base is an integral structure, the boss may be formed on the inner side wall of the base.

[0134] In the disclosed embodiment, a support rib 126 extending toward the base 11 is formed at one end of the outer shell 12 near the base 11, and a boss 114 is formed on the inner wall of the side plate 113 near the first opening 111, and the support rib 126 can abut against the boss 114. Based on this, when the movable connecting plate 17 drives the outer shell 12 to rotate in the first direction, the support rib 126 on the outer shell 12 can rotate relative to the boss 114, which can not only prevent the outer shell 12 from moving toward the bottom plate 112, but also increase the rotation diameter of the outer shell 12, thereby increasing the rotation stability of the outer shell 12.

[0135] In some embodiments, the pan-tilt camera further comprises:

[0136] The second motor 19 includes a second stator 191 and a second rotor 192 . The second rotor 192 rotates relative to the second stator 191 . The second stator 191 is fixed on the outer shell 12 . The second rotor 192 is connected to the camera 131 , and the lens of the camera 131 is oriented perpendicular to the extension direction of the second rotor 192 .

[0137] It can be understood that the PTZ camera further includes a second motor 19, the stator of the second motor 19 is fixedly connected to the outer shell 12, the camera body 13 is connected to the rotor of the second motor 19, and the orientation of the lens included in the camera 131 is perpendicular to the rotor of the second motor 19. Based on this, when the second motor 19 is working, the rotor of the second motor 19 can rotate relative to the stator of the second motor 19, thereby driving the camera body 13 to rotate in the second direction relative to the outer shell 12, so as to expose the camera 131 through the second opening 122 on the outer shell 12 or hide the camera 131 in the outer shell 12.

[0138] In some embodiments, the model of the second motor 19 can be selected as needed, and the embodiments of the present disclosure are not limited to this.

[0139] In some embodiments, the camera body 13 is fixed on the inner housing 16, and the camera 131 is exposed through the third opening 161 on the inner housing 16. The inner housing 16 is fixed on the rotor of the second motor 19, and the lens of the camera 131 is kept perpendicular to the rotor of the second motor 19. Based on this, when the second motor 19 is working, the rotor of the second motor 19 can drive the outer housing 12 to rotate relative to the inner housing 16, thereby driving the camera 131 to rotate.

[0140] In some embodiments, the volume of the inner housing 16 may be larger than the accommodation space enclosed by the first portion of the housing 124. Based on this, when the inner housing 16 rotates relative to the outer housing 12, the inner housing 16 may always cover the second opening 122 on the outer housing 12 to prevent the electronic components in the inner housing 16 from being exposed through the second opening 122, thereby increasing the aesthetics of the PTZ camera.
