Referring to fig. 1 to 2 and fig. 5 to 7, fig. 5 is a schematic sectional view of a camera of the present invention along a direction B-B without a camera, fig. 6 is a schematic structural view of an embodiment of a pressing plate and a sliding block of the present invention, and fig. 7 is a schematic sectional view of a portion of the pressing plate and the sliding block shown in fig. 6 along a direction C-C.
In an embodiment, the cover assembly 20 includes a cover 22 and a pressing plate 23, the cover 22 and the pressing plate 23 enclose to form the accommodating cavity 21, a fixing post 221 extending along a first axis Z1 is disposed in the cover 22, a fixing through hole 231 corresponding to the fixing post 221 is disposed on the pressing plate 23, the fixing post 221 is disposed through the fixing through hole 231, the fixing post 221 and the fixing through hole 231 can move relatively along the first axis Z1 and have a predetermined relative movement amount, and a movement amount of the fixing post 221 and the fixing through hole 231 moving relatively along the first axis Z1 is not greater than the predetermined relative movement amount, so that the pressing plate 23 and the cover 22 can move relatively, and the movement amount is not greater than the predetermined relative movement amount. Optionally, the end of the fixing post 221 is provided with a screw hole, and the gasket of the combination screw can also block the pressing plate 23 from being separated from the fixing post 221 through locking of the combination screw.
The slider 40 and the camera head 10 are relatively fixed in the circumferential direction of the third axis Z3, and the slider 40 can slide relative to the platen 23 about the third axis Z3, so that the camera head 10 can rotate about the third axis Z3, and so that the camera head 10 can rotate about the third axis Z3. That is, upon relative movement between the pressing plate 23 and the housing 22, the slider 40 and the camera head 10 can move relative to the housing 22, so that when the camera head 10 is rotated, the slider 40 can move toward the pressing plate 23, a space is reserved to allow the first and second engaging teeth 51 and 52 to disengage, so that the camera head 10 can rotate relative to the housing assembly 20 about the third axis Z3.
When the slider 40 slides to the first target position W1 closest to the base 30, the tooth height of the first engaging tooth 51 and the smaller tooth height of the second engaging tooth in the first target position W1 is H1When the second axis Z2 and the first axis Z1 form an included angle alpha1If the predetermined relative movement is H0Then H is0≥H1/cosα1To provide a predetermined relative movement H by the combination screw0For example, the predetermined relative movement is a gap between the washer of the combination screw and the pressure plate 23. The second axis Z2 and the first axis Z1 form an included angle alpha1Representing the angle between the camera head 10 and the vertical, when the slider 40 slides to the first target position W1 closest to the base 30, the premise is that: the slider 40 can drive the camera 10 to rotate around the third axis Z3 relative to the pressing plate 23, and it is easy to understand that when the slider 40 drives the camera 10 to be closest to the first target position W1 of the base 30, the amount of movement required when the first engaging tooth 51 and the second engaging tooth 52 are staggered is the smallest, and is H1/cosα1Thus presetting the relative movement amount H0Should be greater than or equal to H1/cosα1That is, the user can rotate the camera 10 at the first target position W1, and the slider 40 moves the camera 10 relative to the pressing plate 23.
If the slide block 40 cannot drive the camera 10 to rotate around the third axis Z3 relative to the pressing plate 23, then H0≥H1/cosα1Wherein α is1Refers to the fixed angle between the second axis Z2 and the first axis Z1.
As shown in fig. 5-7, the first target position W1 is in a vertical direction, then H0Greater than or equal to H1At this time, the camera head 10 is able to rotate relative to the slider 40 and the cover assembly 20 about the second axis Z2.
Referring to fig. 2, 7, 8 and 9, fig. 8 is a partially enlarged view of the pressing plate and the sliding block shown in fig. 7, and fig. 9 is a schematic structural view of a third engaging tooth and a fourth engaging tooth of the present invention, which are separated from each other according to an embodiment of the present invention.
In one embodiment, one of the slider 40 and the cover assembly 20 is provided with third engaging teeth 53 distributed about the third axis Z3, and the other is provided with fourth engaging teeth 54, and the third engaging teeth 53 and the fourth engaging teeth 54 engage with each other to restrict the rotation of the camera head 10 about the third axis Z3. When the camera 10 rotates about the third axis Z3 with respect to the cover assembly 20, the third engaging tooth 53 and the fourth engaging tooth 54 disengage, so that the camera 10 can rotate about the third axis Z3 with respect to the cover assembly 20, and the tilt angle of the camera 10 can be adjusted, taking the camera shown in fig. 1 as an example. And when the camera 10 finishes rotating relative to the cover assembly 20, the third engaging tooth 53 can be engaged with the fourth engaging tooth 54 again, so that the condition that the camera 10 and the cover assembly 20 further rotate relatively is relieved, and the adjusted angle of the camera 10 is reliably fixed.
Specifically, a sliding groove 232 extending around the third axis Z3 is disposed on a side of the pressing plate 23 facing the camera 10, a third engaging tooth 53 is disposed at a bottom of the sliding groove 232, the sliding block 40 is embedded in the sliding groove 232 to limit the movement of the sliding block 40 along the third axis Z3, and a fourth engaging tooth 54 is disposed on a side of the sliding block 40 facing away from the camera 10. When the camera head 10 rotates around the third axis Z3 with respect to the housing assembly 20, the pressing plate 23 and the sliding groove 232 move relatively in the vertical direction (the direction of the first axis Z1), so that the third engaging tooth 53 of the pressing plate 23 and the fourth engaging tooth 54 of the sliding block 40 can be disengaged from each other, the sliding block 40 can drive the camera head 10 to rotate around the third axis Z3, thereby adjusting the angle of the camera head 10, and when the adjustment is completed, the third engaging tooth 53 and the fourth engaging tooth 54 engage with each other again to limit the camera head 10 from further rotating around the third axis Z3. Also, similar to the above-mentioned embodiment, depending on the installation direction of the camera, the movement of the camera head 10 around the third axis Z3 may be performed in a manner of moving along the meshing teeth one by one, or after the third meshing tooth 53 and the fourth meshing tooth 54 are disengaged, when the camera head 10 needs to be fixed at the adjusted angle, the third meshing tooth 53 and the fourth meshing tooth 54 will be meshed with each other again to restrict the camera head 10 from further rotating.
Alternatively, as illustrated in fig. 7, the pressing plate 23 may be provided with two rows of third engaging teeth 53, and correspondingly, the sliding block 40 is also provided with two rows of fourth engaging teeth 54, so as to improve the balance of the sliding block 40 during the movement process and prevent the sliding block 40 from being inclined. The length of the slider 40 in the direction opposite to the two rows of fourth engaging teeth 54 may be different from the length in the direction perpendicular to the opposite direction, or the lengths of the slider 40 in the directions are different, so as to alleviate the situation that the slider 40 rotates along with the rotation of the camera 10 when the camera 10 rotates around the second axis Z2 relative to the slider 40 and the cover assembly 20.
Further, when the slider 40 slides to the second target position W2 farthest from the base 30, the smaller one of the third engaging tooth 53 and the fourth engaging tooth 54 at the second target position W2 has a tooth height H2When the second axis Z2 and the first axis Z1 form an included angle alpha2A predetermined relative movement amount H0≥H2/cosα2. Taking the pressing plate 23 and the slider 40 shown in fig. 6 and 7 as an example, when the second axis Z2 is parallel to the first axis Z1, the third engaging tooth 53 and the fourth engaging tooth 54 are disengaged, and the moving amount required for moving is the smallest, i.e., the height of the smaller of the third engaging tooth 53 and the fourth engaging tooth 54, i.e., H2. Assuming that the relative movement direction of the pressing plate 23 and the slider 40 is a vertical direction, when the slider 40 is moved upward and leftward along the third engaging tooth 53 to rotate the camera head 10, the required relative movement amount of the pressing plate 23 and the slider 40 is gradually increased, and therefore,when the third engaging tooth 53 and the fourth engaging tooth 54 are disengaged when the slider 40 slides to the second target position W2 farthest from the base 30, the required relative movement amount between the slider 40 and the pressing plate 23 is the largest, so the preset movement amount should be greater than or equal to the relative movement amount, i.e. H as mentioned above0≥H2/cosα2。
In combination with "H" as set forth in the above examples0≥H1/cosα1"embodiment H is a case where the camera 10 is rotatable about the second axis Z2 and also rotatable about the third axis Z3 with respect to the cover unit 200Should be greater than or equal to H1/cosα1And H2/cosα2The larger of (i.e., H)0≥H1/cosα1And H0≥H2/cosα2。
Referring to fig. 1, fig. 8 and fig. 10a-b, fig. 10a-b are schematic structural views of an embodiment of the camera according to the present invention.
In one embodiment, as the camera head 10 rotates relative to the housing assembly 20 about the third axis Z3, the angle between the second axis Z2 and the first axis Z1 gradually increases, assuming that the maximum angle between the second axis Z2 and the first axis Z1 is αmax. As shown in fig. 10a, when the vertex angle of the engaging teeth is small, the engaging teeth are negatively engaged, and when the slide block 40 and the pressure plate 23, and/or the slide block 40 and the camera head 10 only move in the vertical direction (i.e. the direction of the first axis Z1), the engaging teeth are inevitably blocked by the engaging teeth engaged therewith, so that the engaging teeth cannot be disengaged from each other, so that the vertex angle of the engaging teeth needs to be set so that the included angle between the first axis Z1 and the second axis Z2 is the maximum included angle αmaxIn the meantime, the sides of the teeth should be at least parallel to the vertical direction to ensure that the teeth can disengage from each other, as illustrated in fig. 10b, the angle between the teeth and the first axis Z1 is γ, and γ should be greater than or equal to 0 °; and it is readily understood that the angular bisector of the addendum angle is on the line of the second axis Z2, then it is possible to see: 1/2 beta-alphamax+ gamma, since gamma is not less than 0 deg., beta can be obtained>2αmax. That is to sayThe meshing tooth crest angle should be greater than twice the maximum included angle between the first axis Z1 and the second axis Z2 to enable the meshing teeth to disengage from each other.

In an alternative embodiment (not shown), button 81 has a fifth engaging tooth, the housing has a sixth engaging tooth, base 30 has a seventh engaging tooth distributed about first axis Z1, the fifth and sixth engaging teeth are disengaged from the seventh engaging tooth when first locking member 61 is released, base 30 and housing assembly 20 are relatively rotatable about first axis Z1, and when the camera is adjusted to a desired angle, the first fastening member is locked such that the fifth and sixth engaging teeth engage with the seventh engaging tooth to restrict further relative rotation of base 30 and housing assembly 20, thereby securely fixing the adjusted angle of camera 10.
In current camera product, when carrying out angle modulation to the camera, common angle modulation mode is through the elasticity degree of adjusting base and cover body subassembly parcel camera, but rotation regulation camera angle when relaxing, base, cover body subassembly and camera interference fit during locking, and frictional force increases in order to fix the camera in the angle of expectation. Or, have the silica gel pad on the base or adopt the plastics material base for the base has certain elasticity, when cover body subassembly and base installation are accomplished, through interference fit such as silica gel pad between base and the cover body subassembly, is fixed in the camera in the angle of expectation, can also prevent under the normal environment vibration, rock and deflect etc. of camera. However, when the camera is adjusted to the desired angle by the above adjusting method, the camera cannot be reliably locked, and the camera is forcibly twisted under the action of external force, or the camera is twisted in the close fitting process, so that the camera deviates from the desired angle of the user, and the use requirement of a specific scene is difficult to meet.
However, when the base and the cover assembly are locked by the first locking member, the camera can be prevented from deflecting by the engagement of the engagement teeth, the adjusted angle of the camera can be reliably fixed, and the camera has a long service life. The pivot hole of the relative slider of pivot of camera rotates, and the pivot hole of slider makes the camera dead axle rotate as the axle sleeve, carries out the rotation to the image of shooing and adjusts, and the pivot also can transmit the inference and drive the slider motion above that. The slider can also drive the relative clamp plate of camera and rotate around the third axis, and the spout of clamp plate can restrict the slider and move towards other directions for the fixed axis rotation can only be done along the spout to the slider, adjusts the camera every single move visual angle.
And, through the interlock tooth interlock between camera and the slider, slider and the clamp plate, when first retaining member loosens, the interlock tooth can break away from each other to adjust the camera angle, and when first retaining member locked, because the interlock tooth interlock each other, can alleviate the skew condition of camera. The pressure plate and the cover body are fixed and can not rotate relatively but can move relatively along the first axis to provide a moving space for the meshing teeth to be disengaged from each other. When the camera leaves the factory, the cover body assembly and the base can be used as two parts for shipment, a user only needs to install the base in the environment firstly, then the cover body assembly is installed in the base, and then the camera can be installed quickly. Furthermore, the camera can lock the cover body and the base through the first locking piece, and can also lock the pressing plate and the cover body, so that the meshing teeth of the internal parts are meshed with each other, and the camera can be locked in the three-axis rotation direction and cannot rotate. Meanwhile, still including the button, further improve the convenience of operation, the button relates to protruding muscle and plays the effect of taking off by force, prevents because of the interlock tooth interlock is stronger, and the condition that still can't deviate from after first retaining member loosens further improve the installation convenience and the reliability of equipment.
