Detailed Implementation

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0041] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0042] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0043] like Figure 1 and Figure 2 As shown, this application provides a camera housing assembly for use in a camera. The camera housing assembly includes a base 1, a housing 2, a connector 3, and an elastic member 4.

[0044] The base 1 and the housing 2 are movably connected by a connector 3 so that the housing 2 can rotate relative to the base 1 in a first rotation direction X or a second rotation direction Z, wherein the first rotation direction X is perpendicular to the second rotation direction Z; that is, the rotation axis of the first rotation direction X is perpendicular to the rotation axis of the second rotation direction Z. For example, when the camera housing is placed on a horizontal surface, the first rotation direction X can be the rotation direction on the horizontal surface, and the second rotation direction Z can be the rotation direction in the vertical direction.

[0045] The outer shell 2 has an inner cavity for accommodating the camera module 7. A lower shell portion 21 is provided at one end of the outer shell 2 near the base 1. A receiving groove 11 is provided on one side of the base 1 near the outer shell 2. The receiving groove 11 is used to accommodate at least part of the lower shell portion 21. The shape of the lower shell portion 21 is adapted to the shape of the receiving groove 11 and both are curved.

[0046] The two ends of the elastic element 4 abut against the connecting element 3 and the side of the lower shell 21 away from the base 1, respectively.

[0047] According to the embodiments provided in this application, it should be noted that:

[0048] The base 1 is used to support the outer shell 2. The base 1 can be set on a horizontal table, tabletop or other flat surface, or it can be installed at an angle on a wall, pole, bracket or other scene.

[0049] One end of the connector 3 is connected to the outer shell 2, and the other end is connected to the base 1. Exemplarily, the connector 3 is movably connected to the outer shell 2, and fixedly connected to the base 1, so that the outer shell 2 can rotate relative to the base 1, achieving dual-axis rotation. It is understood that the aforementioned "fixed connection" refers to a connection method relative to the movable connection, meaning that the connector 3 and the base 1 remain relatively stationary in a normal state.

[0050] The lower shell portion 21 is located at the bottom of the outer shell 2 and is used to mate and contact with the base 1. For example, as shown... Figure 1 and Figure 4 As shown, the lower shell 21 is hemispherical, and the wall of the receiving groove 11 is curved, specifically spherical. The shape of the lower shell 21 is the same as the shape of the receiving groove 11 and the size is adapted, so that the lower shell 21 can flexibly rotate in the receiving groove 11 along the first rotation direction X 360°, and can also fully contact and cooperate with the wall of the receiving groove 11, increasing the contact area between the lower shell 21 and the receiving groove 11, and improving the connection stability between the outer shell 2 and the base 1.

[0051] For example, the elastic element 4 is a compression spring. The elastic element 4 extends along the docking direction of the outer shell 2 and the lower shell 21, and the elastic element 4 can undergo elastic deformation along its own length extension direction. The elastic element 4 is located in the outer shell 2 and is in a compressed state. The compressed elastic element 4 can transmit compressive force to the lower shell 21, thereby making the lower shell 21 fit tightly against the receiving groove 11, increasing the compressive force between the lower shell 21 and the receiving groove 11 and the damping during rotation, simulating the rotational feel of a magnetic connection. The end of the elastic element 4 can directly or indirectly abut against the inner wall of the lower shell 21, as long as the elastic element 4 can transmit compressive force to the lower shell 21.

[0052] The pitch, wire diameter, height, and other parameters of the elastic element 4 can be adjusted according to the rotational damping force requirements of the camera housing assembly. For example, the elastic element 4 is made of piano wire with a wire diameter of 0.6mm to 0.8mm and a height of 5mm to 8mm.

[0053] The camera housing assembly provided in this application embodiment has a curved shape for the lower housing 21 and the receiving groove 11, and the two ends of the elastic member 4 abut against the connecting member 3 and the side of the lower housing 21 away from the base 1, which increases the contact area between the lower housing 21 and the receiving groove 11. The squeezing force of the elastic member 4 on the lower housing 21 increases the force between the lower housing 21 and the receiving groove 11, which improves the damping effect and rotation feel when manually turning, and eliminates the cost of setting up a magnetic suction assembly, which helps to reduce production costs.

[0054] The groove wall of the receiving groove 11 and / or the lower shell 21 are polished surfaces for contacting the receiving groove 11.

[0055] After the groove wall of the receiving groove 11 and / or the surface of the lower shell 21 are polished, they are relatively bright and smooth, which not only improves the aesthetics and wear resistance, but also helps to reduce the coefficient of friction between the receiving groove 11 and the lower shell 21, making the relative rotation between the outer shell 2 and the base 1 smoother and improving the rotation feel.

[0056] In one embodiment, the contact area between the lower shell 21 and the receiving groove 11 is 10 cm². 2 ~13cm 2 .

[0057] This design ensures that the lower shell 21 and the receiving groove 11 have sufficient contact area, guaranteeing the damping effect and turning feel during manual steering.

[0058] In one specific embodiment, the lower shell 21 has a guide groove 211 that extends in an arc shape along the second rotation direction Z. The connector 3 is inserted into the guide groove 211 and can slide in the guide groove 211, so that the outer shell 2 can rotate relative to the base 1 along the second rotation direction Z.

[0059] like Figure 1 As shown, the guide groove 211 is located at the bottom of the lower shell 21. The connector 3 passes through the guide groove 211 from the outer shell 2 and connects to the base 1. By manually applying force to the outer shell 2, the connector 3 moves relative to the guide groove 211 in the extension direction of the guide groove 211. Since the base 1 is relatively fixed, the outer shell 2 rotates relative to the base 1 in the second rotation direction Z, thereby realizing the adjustment of the camera's viewing angle in the height direction.

[0060] The extension length of the guide groove 211 determines the range of angles in which the camera rotates along the second rotation direction Z. Since different models of cameras have different rotation angle requirements, the extension length of the guide groove 211 can be set according to actual needs, and this application does not make specific limitations.

[0061] Furthermore, such as Figure 5 As shown, the outer shell 2 also includes an upper shell 22 that is connected to the lower shell 21. The side wall of the upper shell 22 is provided with a light-transmitting hole 221 for exposing the camera module 7. The light-transmitting hole 221 and the guide groove 211 are distributed at intervals along the docking direction of the upper shell 22 and the lower shell 21, so that the optical axis of the camera module 7 can rotate along the second rotation direction Z.

[0062] like Figure 2 As shown, the upper shell 22 and the lower shell 21 are joined together to form an inner cavity for accommodating the camera module 7 and other components. The outer shell 2 is cylindrical in shape.

[0063] Optionally, the upper shell 22 and the lower shell 21 are connected by means of snap-fit ​​connection, tenon and mortise connection, bolt connection, etc.; or, the upper shell 22 and the lower shell 21 are integrally formed.

[0064] For example, the upper shell 22, the lower shell 21 and the base 1 are all plastic parts, which not only have simple processing technology, but also have the advantages of being lightweight, chemically stable and low in manufacturing cost.

[0065] like Figure 5 As shown, the ends of the light-transmitting hole 221 and the guide groove 211 are spaced apart and aligned along the height direction of the outer shell 2, so that the optical axis of the camera module 7 and the extension line of the guide groove 211 are in the same plane, thereby realizing the adjustment of the pitch angle of the camera module 7.

[0066] In one embodiment, the camera housing assembly further includes a first friction plate 5, which covers the side of the guide groove 211 away from the base 1. The first friction plate 5 has a dimension in the width direction of the guide groove 211 that is greater than the width of the guide groove 211. The connector 3 passes through the first friction plate 5 and the guide groove 211 in sequence to connect with the base 1. The elastic member 4 is sleeved on the outer periphery of the connector 3 and located on the side of the first friction plate 5 away from the base 1.

[0067] like Figure 3 As shown, one end of the elastic member 4 abuts against the connecting member 3, and the other end abuts against the side surface of the first friction plate 5 away from the base 1. The elastic member 4 can apply a squeezing force to the first friction plate 5, so that the first friction plate 5 fits tightly with the inner wall of the lower shell 21.

[0068] By setting the first friction plate 5, the inner wall of the lower shell 21 can be protected to a certain extent, preventing the connector 3 from causing wear to the inner wall of the lower shell 21. At the same time, since the dimension of the first friction plate 5 in the width direction of the guide groove 211 is larger than the width of the guide groove 211, it can also prevent the connector 3 from coming off the lower shell 21, thus improving the connection stability between the connector 3 and the lower shell.

[0069] Furthermore, the camera housing assembly also includes a second friction plate 6, which is fixed to the side surface of the lower housing 21 away from the base 1 and has a corresponding through hole 61 adapted to the guide groove 211. The first friction plate 5 is located between the elastic member 4 and the second friction plate 6 so that the first friction plate 5 and the second friction plate 6 are tightly abutted under the action of the elastic member 4.

[0070] Specifically, the second friction plate 6 covers the surface of the lower shell 21 opposite to the base 1, and its shape is adapted to the shape of the inner wall of the lower shell 21, such as... Figure 1 As shown, the second friction plate 6 is curved.

[0071] For example, the second friction plate 6 is fixed inside the lower shell 21 by means of bonding, welding or other methods.

[0072] Since the first friction plate 5 is located between the elastic element 4 and the second friction plate 6, the first friction plate 5 and the second friction plate 6 are in close contact under the pressure of the elastic element 4. When the outer shell 2 rotates relative to the base 1, the first friction plate 5 and the second friction plate 6 also generate relative motion and rub against each other, which further enhances the damping effect when manually steering, making the steering feel closer to the steering feel of magnetic connection.

[0073] In one specific embodiment, both the first friction plate 5 and the second friction plate 6 are metal parts.

[0074] For example, both the first friction plate 5 and the second friction plate 6 are stainless steel parts, such as the first friction plate 5 and the second friction plate 6 being made of stainless steel with a hardness specification of 3 / 4H.

[0075] By setting the first friction plate 5 and the second friction plate 6 to be metal parts, the first friction plate 5 and the second friction plate 6 have high strength and wear resistance, which helps to improve the durability and service life of the camera housing.

[0076] In one embodiment, the contact area between the first friction plate 5 and the second friction plate 6 is 30 mm². 2 ~50mm 2 For example, the contact area between the first friction plate 5 and the second friction plate 6 can be 30 mm. 2 40mm 2 50mm 2 wait.

[0077] This setting ensures that the first friction plate 5 and the second friction plate 6 have sufficient contact area, guaranteeing the damping effect and steering feel during manual steering.

[0078] In one embodiment, the surface of the first friction piece 5 that contacts the second friction piece 6 is provided with an electroplated chromium layer; and / or, the surface of the second friction piece 6 that contacts the first friction piece 5 is provided with an electroplated chromium layer.

[0079] This design not only improves the hardness, wear resistance, and chemical stability of the contact surfaces of the first friction plate 5 and the second friction plate 6, but also makes the contact surfaces smoother, which helps to reduce the coefficient of friction and makes the relative rotation between the first friction plate 5 and the second friction plate 6 smoother and without stagnation.

[0080] In one embodiment, the thickness of the first friction plate 5 is 0.4 mm to 0.6 mm. For example, the thickness of the first friction plate 5 can be 0.4 mm, 0.5 mm, 0.6 mm, etc.

[0081] When the thickness of the first friction plate 5 is less than 0.4 mm, the first friction plate 5 is likely to reach its wear resistance limit; when the thickness of the first friction plate 5 is greater than 0.6 mm, it will increase the weight and manufacturing cost of the camera housing assembly.

[0082] This design ensures the service life of the first friction plate 5 while reducing the weight and manufacturing cost of the camera housing assembly.

[0083] In one embodiment, the thickness of the second friction plate 6 is 0.8 mm to 1 mm. For example, the thickness of the first friction plate 5 can be 0.8 mm, 0.9 mm, 1 mm, etc.

[0084] Similar to the thickness setting of the first friction plate 5, this setting helps to reduce the weight and manufacturing cost of the camera housing assembly while ensuring the service life of the second friction plate 6.

[0085] In one embodiment, such as Figure 3 As shown, the connector 3 is a threaded fastener. The receiving groove 11 has a mounting hole 111, and a nut structure 112 is provided in the mounting hole 111. The connector 3 is threadedly connected to the nut structure 112.

[0086] Connector 3 is a threaded fastener such as a bolt or screw.

[0087] For example, the nut structure 112 has an internal thread on the inner wall of the mounting hole 111, that is, the mounting hole 111 is a threaded hole, and the connector 3 is directly threadedly connected to the mounting hole 111.

[0088] By setting the connector 3 to be threadedly connected to the nut structure 112, the connector 3 and the base 1 are fixedly connected, which is convenient to install and helps to reduce assembly time.

[0089] Furthermore, the nut structure 112 is a pre-embedded nut, which is inserted into the mounting hole 111 and integrally injection molded with the base 1.

[0090] The inner wall of the pre-embedded nut has an internal thread that matches the external thread of the connector 3. By integrally injection molding the pre-embedded nut and the base 1, the connection stability between the pre-embedded nut and the base 1 is improved.

[0091] like Figure 6 As shown, this application embodiment also provides a camera, which includes the camera housing assembly provided in any of the above embodiments, and further includes a camera module 7, which is housed in the outer shell 2 of the camera housing assembly.

[0092] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
