Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the embodiments of the present utility model will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a pan-tilt camera according to an embodiment of the present utility model, where pan-tilt camera 000 may include: a base 100 and a camera body 200. In order to more clearly see the structure of the base 100, please refer to fig. 2, fig. 2 is an exploded view of the pan-tilt camera shown in fig. 1. Pan-tilt camera 000 may further include: and a spacing assembly 300.

The base 100 in the pan-tilt camera 000 may have a receiving cavity 100a and a bearing groove 100b, and the bearing groove 100b may have an opening O communicating with the receiving cavity 100a. The receiving cavity 100a in the base 100 may be used to receive part of the working devices required for the operation of the pan-tilt camera 000, for example, a control circuit board, a driving motor, and the like.

The camera body 200 in the pan-tilt camera 000 may include: a housing 201, a camera 202, and an assembly 203.

Wherein a portion of the housing 201 of the camera body 200 may be located within the carrying recess 100b of the base 100. The housing 201 of the camera body 200 can be supported by the bearing groove 100b of the base 100, so that the camera body 200 can be more stably placed on the base 100.

The camera 202 in the camera body 200 may be fixed inside the housing 201, and a portion of the housing 201 where the camera 202 is disposed may be located outside the bearing groove 100 b. In this way, the cameras 202 in the camera body 200 can be ensured to be distributed outside the bearing groove 100b, so that the base 100 can not shade the cameras 202, and the camera body 200 can shoot an image through the cameras 202.

The assembly 203 of the camera body 200 may be fixedly connected to a side of the housing 201 facing the bearing recess 100b, and the assembly 203 may extend into the accommodating cavity 100a of the base 100. Here, the assembly portion 203 and the base 100 may be connected by various means such as screw connection, ultrasonic welding, and dispensing connection, and the connection means between the assembly portion 203 and the base 100 is not limited in the present utility model.

In order to more clearly see the matching relationship between the base 100 and the camera body 200, please refer to fig. 2 and 3, and fig. 3 is a cross-sectional view of the pan-tilt camera shown in fig. 1. The limiting assembly 300 in the pan-tilt camera 000 may be located in the receiving cavity 100a of the base 100, and the limiting assembly 300 may be fixedly connected with an end of the assembly 203 in the camera body 200 facing away from the housing 201. Here, after the limiting assembly 300 is fixedly connected with the housing 201 in the camera body 200, the limiting assembly 300 can rotate together with the camera body 200 with respect to the base 100. Wherein the width of the spacing assembly 300 in at least one direction is greater than the width of the opening O in the base 100. Like this, not only can guarantee through spacing subassembly 300 that camera body 200 can not follow and bear the weight of in the recess 100b and drop to guarantee to carry out stable relative rotation between camera body 200 and the base 100, and at camera body 200 for base 100 pivoted in-process, can also retrain the position of camera body 200 through spacing subassembly 300, thereby can reduce the probability that camera body 200 takes place relative rocking with base 100.

By way of example, since the width of the spacing assembly 300 in at least one direction is greater than the width of the opening O in the base 100, and the end of the assembly 203 of the camera body 200 facing away from the housing 201 may be fixedly connected with the spacing assembly 300. Therefore, in the process of rotating the camera body 200, when a relative shaking trend is generated between the camera body 200 and the base 100, the assembly portion 203 in the camera body 200 drives the limiting assembly 300 and the base 100 to also generate a relative shaking trend. In this case, since the width of the spacing assembly 300 in at least one direction is greater than the width of the opening O in the base 100, at least a portion of the spacing assembly 300 may abut against the inner wall near the opening O of the base 100 when a tendency for relative sloshing occurs between the spacing assembly 300 and the base 100. In this way, when a tendency of relative shaking occurs between the camera body 200 and the base 100, the limiting assembly 300 can apply a restraining force to the camera body 200, so that the camera body 200 is stably rotated in the bearing groove 100b of the base 100. Thus, the probability of relative shaking between the camera body 200 and the base 100 can be effectively reduced only by the limiting assembly 300 without arranging a metal bearing in the base 100. And, the material of the limiting component 300 can be made of a material with low cost, for example, a plastic material. Thus, by setting the limiting component 300 in the pan-tilt camera 000, the probability of relative shake between the camera body 200 and the base 100 can be ensured to be low, and the production cost of the pan-tilt camera 000 can be effectively reduced.

In summary, the present utility model provides a pan-tilt camera, including: base, camera body and spacing subassembly. Because the width of the spacing component in at least one direction is greater than the width of the opening in the base, and the end of the assembly portion of the camera body facing away from the housing can be fixedly connected with the spacing component. Therefore, in the process of rotating the camera body, when the trend of relative shaking is generated between the camera body and the base, the assembly part in the camera body can drive the limit component and the base to generate the trend of relative shaking. In this case, since the width of the spacing assembly in at least one direction is greater than the width of the opening in the base, at least a portion of the spacing assembly may abut the inner wall near the opening of the base when a tendency for relative sloshing occurs between the spacing assembly and the base. Like this, when producing the trend of rocking relatively between camera body and the base, spacing subassembly can exert the confining force to the camera body for the camera body is stable rotates in the bearing groove of base. So, need not to set up metal bearing in the base, only need through spacing subassembly can effectually reduce the probability that camera body and base take place to rock relatively. And the material of the limiting component can be made of a material with lower manufacturing cost. Like this, through set up the mode of spacing subassembly in the cloud platform camera, both can guarantee that the probability that camera body and base take place to rock relatively is lower, can effectual lower cloud platform camera's manufacturing cost again.

In an embodiment of the present utility model, please refer to fig. 4, fig. 4 is a schematic structural diagram of a base according to an embodiment of the present utility model. The bottom surface of the bearing groove 100b in the base 100 may have first support ribs J1 distributed around the opening O of the base 100, and the first support ribs J1 may abut against a portion of the housing 201 located within the bearing groove 100 b. Thus, in the process of rotating the camera body 200, the contact area between the housing 201 in the camera body 200 and the base 100 can be reduced through the first supporting rib J1, so that the friction force generated between the camera body 200 and the base 100 can be reduced, and the camera body 200 can be rotated more smoothly.

As shown in fig. 4 and fig. 5, fig. 5 is a cross-sectional view of another pan-tilt camera according to an embodiment of the present utility model. The shape of the bearing groove 100b in the base 100 may be matched with the shape of the housing 201 in the camera body 200, so that when the first support rib J1 exists between the camera body 200 and the bottom surface of the bearing groove 100b, a gap may exist between the camera body 200 and the bottom surface of the bearing groove 100 b. In this way, the contact area between the camera body 200 and the mount 100 can be ensured to be small.

It should be noted that, as shown in fig. 4 and 5, since the shape of the bearing groove 100b in the base 100 may be like the shape of the housing 201 in the camera body 200, when there is a gap between the camera body 200 and the bottom surface of the bearing groove 100b, there may be a first gap K1 between the portion of the housing 201 located inside the bearing groove 100b and the side surface of the bearing groove 100 b. In this way, the contact area between the housing 201 in the camera body 200 and the base 100 can be further reduced, so that the camera body 200 can be rotated more smoothly. In addition, since the first gap K1 may be formed between the housing 201 and the side surface of the bearing groove 100b, in the rotation process of the camera body 200, the probability that the housing 201 contacts with the side surface of the bearing groove 100b is low, so that the camera body 200 can be more stably located in the bearing groove 100b, and the probability that the housing 201 and the base 100 shake relatively is further reduced.

In an embodiment of the present utility model, referring to fig. 5, the pan-tilt camera 000 may further include: the sleeve 400 fixedly connected with the inner wall of the accommodating cavity 100a, the sleeve 400 may be distributed around the opening O of the base 100, the limiting assembly 300 may be located at a side of the sleeve 400 facing away from the bearing groove 100b, and the assembling portion 203 may be located in the sleeve 400. Like this, at camera body 200 pivoted in-process, sleeve 400 can carry out spacingly to camera body 200 for camera body 200 can rotate more stably in base 100, and can avoid taking place behind the cloud platform camera 000 receives external environment interference, the adverse condition that camera body 200 drops from base 100.

As shown in fig. 5, for example, since the assembly 203 of the camera body 200 may be located in the sleeve 400, the sleeve 400 may restrict the position of the assembly 203 of the camera body 200 during rotation of the camera body 200, and when the camera body 200 is relatively swayed with the base 100 in a direction perpendicular to the axis of the sleeve 400, the assembly 203 may abut against the inner wall of the sleeve 400. In this case, the sleeve 400 may apply a restraining force to the assembling portion 203, and the camera body 200 may be more stably rotated in the bearing groove 100b of the base 100 by the restraining force. Also, since the spacing assembly 300 may be located at a side of the sleeve 400 facing away from the bearing groove 100b, and the width of the spacing assembly 300 in at least one direction is greater than the width of the opening O of the base 100, that is, the width of the spacing assembly 300 in at least one direction may be greater than the width of the sleeve 400. Accordingly, when the camera body 200 generates a relative shaking with the base 100 in a direction along the axis of the sleeve 400, the stopper assembly 300 may abut against the end of the sleeve 400, and the sleeve 400 may apply a restraining force to the stopper assembly 300. In this way, the sleeve 400 can limit the camera body 200 in both the direction along the axis of the sleeve 400 and the direction perpendicular to the axis of the sleeve 400. Thus, the camera body 200 can be ensured to rotate in the bearing groove 100b of the base 100 more stably.

In the present utility model, as shown in fig. 5, a second gap K2 may be provided between the side of the sleeve 400 facing away from the bearing groove 100b and the limiting assembly 300. Like this, can further reduce the area of contact between spacing subassembly 300 and sleeve 400, avoid taking place at camera body 200 pivoted in-process, spacing subassembly 300 and sleeve 400 take place to contact, lead to sleeve 400 to exert the restriction force to spacing subassembly 300, and then lead to the unable normal pivoted adverse condition of camera body 200. For example, since the second gap K2 may be formed between the side of the sleeve 400 away from the bearing groove 100b and the limiting component 300, during the rotation of the camera body 200, the probability that the assembly portion 203 contacts with the inner wall of the sleeve 400 is low, so that the camera body 200 can be more stably located in the bearing groove 100b, and the probability that the housing 201 and the base 100 shake relatively is further reduced.

Optionally, as shown in fig. 5, the pan-tilt camera 000 may further include: the lubrication layer 500 located within the second void K2, that is, the lubrication layer 500 may be located between the sleeve 400 and the spacing assembly 300. In this way, the camera body 200 can be more stably rotated in the bearing groove 100b of the base 100 by the lubrication layer 500. For example, if the camera body 200 moves in a direction along the axis of the sleeve 400 during rotation of the camera body 200, the sleeve 400 may apply a restraining force to the limit assembly 300. Since the lubrication layer 500 may be provided between the sleeve 400 and the spacing assembly 300, the sleeve 400 may spacing the spacing assembly 300 by the lubrication layer 500. In this way, the sleeve 400 can effectively constrain the movement of the camera body 200 in the direction along the axis of the sleeve 400 without affecting the rotation of the camera body 200 within the recess of the base 100. In this way, the camera body 200 can be made to rotate more stably within the bearing groove 100 b.

In an embodiment of the present utility model, referring to fig. 5, a third gap K3 may be provided between the inner wall of the sleeve 400 in the pan-tilt camera 000 and the surface of the assembly 203. In this way, the contact area between the assembly portion 203 and the sleeve 400 in the camera body 200 can be further reduced, and the problem that the assembly portion 203 and the sleeve 400 are in contact during the rotation of the camera body 200, which results in the sleeve 400 applying a restraining force to the assembly portion 203 and further results in the failure that the camera body 200 cannot rotate normally is avoided.

As shown in fig. 5, since the third gap K3 may be formed between the inner wall of the sleeve 400 and the surface of the assembly portion 203, the probability that the assembly portion 203 contacts with the inner wall of the sleeve 400 is low during the rotation of the camera body 200, so that the camera body 200 can be more stably located in the bearing groove 100 b. In addition, the problem that the housing 201 and the base 100 shake relatively due to the contact between the assembly 203 and the inner wall of the sleeve 400 during the rotation of the camera body 200 can be avoided.

In the present utility model, as shown in fig. 5, the sleeve 400 may have second support ribs J2 on an inner wall thereof, and the second support ribs J2 may be in contact with a surface of the assembling portion 203. In this way, the third gap K3 can be stably maintained between the sleeve 400 and the assembling portion 203 by the second support rib J2 during rotation of the camera body 200. Moreover, through the second supporting rib J2, the sleeve 400 can play a role of limiting and supporting the assembly part 203, so that the camera body 200 can rotate in the bearing groove 100b of the base 100 more stably.

For example, if the camera body 200 moves in a direction perpendicular to the axis of the sleeve 400 during rotation of the camera body 200, the sleeve 400 may apply a restraining force to the assembling portion 203. Since the second supporting rib J2 may be provided between the sleeve 400 and the assembling portion 203, the sleeve 400 may limit the limit assembly 300 through the second supporting rib J2. In this way, the sleeve 400 can effectively restrict the movement of the camera body 200 in the direction perpendicular to the axis of the sleeve 400, and does not affect the rotation of the camera body 200 in the recess of the base 100. In this way, the camera body 200 can be made to rotate more stably within the bearing groove 100 b.

In an embodiment of the present utility model, please refer to fig. 6, fig. 6 is a schematic structural diagram of another pan-tilt camera according to an embodiment of the present utility model. Pan-tilt camera 000 may further include: the driving assembly 600 fixed in the receiving chamber 100a, the driving assembly 600 may be connected with the limiting assembly 300. In this way, the driving assembly 600 may drive the camera body 200 to rotate by driving the limiting assembly 300 to rotate. In this way, the pan-tilt camera 000 can more conveniently control the camera body 200 to rotate in the bearing groove 100b of the base 100 through the driving assembly 600.

As shown in fig. 6 and 7, fig. 7 is a schematic structural diagram of a driving assembly according to an embodiment of the present utility model. The driving assembly 600 may include: the driving motor 601 and the output shaft 602, one side of the limit assembly 300 near the driving assembly 600 may have a mounting groove U for mounting the output shaft 602. The output shaft 602 may be fixedly coupled to the spacing assembly 300 within the mounting slot U of the spacing assembly 300. Thus, the driving assembly 600 can drive the output shaft 602 to rotate through the driving motor 601, so that the limiting assembly 300 can be driven to rotate through the output shaft 602. Since the limiting component 300 can be fixedly connected with the assembling portion 203 of the camera body 200, the limiting component 300 can drive the camera body 200 to rotate synchronously. In this way, the pan-tilt camera 000 can more conveniently control the camera body 200 to rotate in the bearing groove 100b of the base 100 through the driving assembly 600. Here, in order to ensure that the pan-tilt camera 000 can more stably control the rotation of the camera body 200 through the driving assembly 600, it should be ensured that the axis of the mounting groove U of the limiting assembly 300, the axis of the limiting assembly 300, and the axis of the assembling portion 203 coincide. Thus, in the process that the driving assembly 600 drives the limiting assembly 300 to rotate, the limiting assembly 300 can drive the camera body 200 to rotate around the axis of the camera body 200, so that the rotation stability of the camera body 200 can be ensured to be higher.

In the present utility model, as shown in fig. 8 and 9, fig. 8 is a schematic structural view of another base provided in an embodiment of the present utility model, and fig. 9 is an exploded view of the base shown in fig. 8. The base 100 of the pan-tilt camera 000 may include: the end of the base body 101 may have a bearing groove 100b, and a support base plate 102 detachably connected to a side of the base body 101 facing away from the bearing groove 100 b. Wherein, after the base body 101 and the supporting base plate 102 are connected, the base body 101 and the supporting base plate 102 may be used to enclose the accommodating chamber 100a. Thus, during the assembly process of the pan-tilt camera 000, an operator may first install the relevant working devices required for working the pan-tilt camera 000 from the side of the base body 101 facing away from the bearing groove 100 b. After the installation of the relevant working devices is completed, an operator can connect the supporting base plate 102 with the base body 101, so that the base body 101 and the supporting base plate 102 enclose a containing cavity 100a to protect the relevant working devices, and the assembly work of the cradle head camera 000 can be completed efficiently and rapidly. And, when the operation fault of the pan-tilt camera 000 needs to be repaired and checked, an operator can cancel the connection between the supporting base plate 102 and the base body 101, so that the repair and the check of the pan-tilt camera 000 can be more conveniently performed.

For example, during the assembling process of the pan-tilt camera 000, an operator may first match the assembling portion 203 of the camera body 200 with the bearing groove 100b on the base body 101, and then the operator may fixedly connect the limiting assembly 300 with the assembling portion 203 of the camera body 200 on a side of the base body 101 facing away from the bearing groove 100 b. After the assembly of the limiting assembly 300 is completed, an operator can fixedly connect the output shaft 602 of the driving assembly 600 with the limiting assembly 300 on the side of the base body 101 away from the bearing groove 100 b. Finally, the operator can connect the support base plate 102 with the side of the base body 101 facing away from the carrying recess 100 b. Thus, an operator can efficiently and quickly complete the assembly work of the pan-tilt camera 000.

In summary, the present utility model provides a pan-tilt camera, including: base, camera body and spacing subassembly. Because the width of the spacing component in at least one direction is greater than the width of the opening in the base, and the end of the assembly portion of the camera body facing away from the housing can be fixedly connected with the spacing component. Therefore, in the process of rotating the camera body, when the trend of relative shaking is generated between the camera body and the base, the assembly part in the camera body can drive the limit component and the base to generate the trend of relative shaking. In this case, since the width of the spacing assembly in at least one direction is greater than the width of the opening in the base, at least a portion of the spacing assembly may abut the inner wall near the opening of the base when a tendency for relative sloshing occurs between the spacing assembly and the base. Like this, when producing the trend of rocking relatively between camera body and the base, spacing subassembly can exert the confining force to the camera body for the camera body is stable rotates in the bearing groove of base. So, need not to set up metal bearing in the base, only need through spacing subassembly can effectually reduce the probability that camera body and base take place to rock relatively. And the material of the limiting component can be made of a material with lower manufacturing cost. Like this, through set up the mode of spacing subassembly in the cloud platform camera, both can guarantee that the probability that camera body and base take place to rock relatively is lower, can effectual lower cloud platform camera's manufacturing cost again.
