[0065] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0066] The present disclosure provides an angle adjustment device 100, such as Figure 2 As shown, it includes a housing 101 and a base 104 .

[0067] The housing 101 may include a first housing 1011, a second housing 1012, a chamber 102, and a first guide 103. After the first housing 1011 and the second housing 1012 are assembled, the inner surface of the first housing 1011 and the inner surface of the second housing 1012 jointly define a first curved surface 1013. The chamber 102 is defined by the first housing 1011 and the second housing 1012. The first guide 103 is located in the chamber 102 and is disposed on the first curved surface 1013, and the portion of the first guide 103 in contact with the first curved surface 1013 includes a second curved surface 1031. The base 104 is connected to the housing 101, and the base 104 includes a third curved surface 1041 that matches the shape of the first curved surface 1013.

[0068] The angle adjustment device 100 further includes a second guide 105, which is at least partially located in the chamber 102, and includes a guide portion 1051 and a connection portion 1052, wherein the guide portion 1051 contacts the first guide 103, and the connection portion 1052 extends through the first guide 103 to the outside of the housing 101 and is connected to the base 104. Along the angle adjustment path formed in the second curved surface 1031, the first guide 103 can be displaced relative to the second guide 105 to adjust the angle of the housing 101 relative to the base 104. The guide portion 1051 of the second guide 105 provides damping between the first guide 103 and the second guide 105 to at least temporarily fix the housing 101 to the adjustment angle.

[0069] The shell can be understood as Figure 1 The base of the part indicated by the reference numeral 101 can be understood as Figure 1 The portion indicated by the reference numeral 104 is the base of the housing 101. The base 104 can be placed on a horizontal surface, such as a desktop, a wall, etc., and can be oriented as shown in the drawings or inverted (such as Figure 1 Upside down) on top of a wall, or tilted (for example Figure 1 Rotate 90 degrees) and set it on the wall.

[0070] Specifically, Figure 2 As shown, the shell 101 may include a first shell 1011 and a second shell 1012. When the first shell 1011 and the second shell 1012 are connected to each other, the inner surface of the first shell 1011 and the inner surface of the second shell 1012 constitute the inner surface of the shell 101. The area enclosed by the inner surface of the first shell 1011 and the area enclosed by the inner surface of the second shell 1012 together constitute a chamber 102. The chamber 102 is used to at least accommodate the first guide member 103 and may also accommodate electronic components.

[0071] The first shell can be understood as Figure 2 The front shell shown by the left label 1011, the second shell can be understood as Figure 2 The back shell is shown as reference numeral 1012. The connection between the first shell 1011 and the second shell 1012 can be a snap connection, for example Figure 2 As shown, the first housing 1011 is provided with a first joint portion 10111, and the second housing 1012 is provided with a second joint portion 10122. The first housing 1011 and the second housing 1012 are snap-connected via the first joint portion 10111 and the second joint portion 10122. Such a configuration facilitates the disassembly and assembly of the first housing 1011 and the second housing 1012, and is conducive to maintenance.

[0072] In the above example, the first joining portion 10111 can be set along the edge of the first shell 1011, and the second joining portion 10122 can be set along the edge of the second shell 1012. After the two are snap-connected, the gap between the edge of the first shell 1011 and the edge of the second shell 1012 can be further closed to improve the sealing of the component shell.

[0073] In other embodiments, in order to strengthen the connection between the first shell 1011 and the second shell 1012, the two can also be fastened together by other fastening devices. For example, in one embodiment, Figure 2 , Figure 3As shown, the first shell 1011 is provided with a first connection structure at a portion between the first guide 103 and the base 104, and the second shell 1012 is provided with a second connection structure at a portion between the first guide 103 and the base 104. After the first shell 1011 and the second shell 1012 are snap-connected, the first connection structure is coaxial with the second connection structure. A second through hole is formed on the surface of the base 104. The angle adjustment device 100 further includes a shell fastener, which passes through the second through hole and is fixedly connected to both the first connection structure and the second connection structure.

[0074] When assembling this embodiment, the first guide member 103 is connected to the second housing 1012, the guide portion 1051 of the second guide member 105 is matched and connected to the first guide member 103, the connection portion 1052 of the second guide member 105 is connected to the first substrate 1042 of the base 104, the first housing 1011 is snap-connected to the second housing 1012, the first connection structure is coaxial with the second connection structure, the adjustment angle of the housing 101 is adjusted along the angle adjustment path, the second through hole is coaxial with the first connection structure and the second connection structure, the housing fastener is passed through the second through hole and fixedly connected to the first connection structure and the second connection structure, the counterweight 1044 and the second substrate 1043 are connected to the first substrate 1042, and the angle adjustment device 100 is assembled. The housing fastener can be a screw.

[0075] According to this embodiment, the shell fastener is shielded by the base 104 after the connection is completed, so as to prevent the shell fastener from being exposed to the external environment, improve the user's perception, and prevent it from being corroded by the external environment.

[0076] The first curved surface 1013 can be understood as Figure 2 The bottom of the inner surface of the first shell 1011 and the bottom of the inner surface of the second shell 1012 constitute the bottom of the inner wall of the chamber 102. In other embodiments, the first curved surface 1013 may also be located only on the inner surface of the first shell 1011 or the inner surface of the second shell 1012, depending on the shapes of the first shell 1011 and the second shell 1012.

[0077] The first guide member Figure 2 , Figure 3 , Figure 5 The part shown by the middle number 103, the lower side of the first guide member 103 in the figure has a second curved surface 1031, when the first guide member 103 is arranged in the chamber 102, the second curved surface 1031 is abutted against the first curved surface 1013, which can be partially abutted or completely abutted, depending on the curvature of the first curved surface 1013 and the second curved surface 1031.

[0078] The angle adjustment path in the second curved surface 1031 can be obtained by Figure 5 The housing 101 is defined by the guide groove indicated by the middle number 1032. The housing 101 can be displaced along the length direction of the guide groove 1032 to adjust the inclination angle of the housing 101 relative to the base (i.e., the adjustment angle). During the displacement of the housing 101, the first guide member 103 and the housing 101 remain relatively stationary, so that the two are displaced synchronously.

[0079] The base 104 may include a first substrate 1042 and a second substrate 1043 detachably connected to the first substrate 1042, wherein the first substrate may be understood as Figure 2 The upper cover shown by reference numeral 1042 and the second substrate can be understood as Figure 2 The bottom cover is shown as numeral 1043. The first substrate 1042 and the second substrate 1043 may be connected by snap-fit ​​or by other fastening devices such as screws. Figure 2 The third curved surface 1041 is formed on a surface of the first substrate 1042 facing the housing 101 .

[0080] If the first substrate 1042 is Figure 2 The bottom cover is shown as 1043, and the second substrate 1043 is Figure 2 For the upper cover denoted by 1042 , the third curved surface 1041 is formed on the surface of the second substrate 1043 facing the housing 101 .

[0081] On this basis, in order to further increase the stability of the base 104 and prevent the base 104 from shaking when the shell 101 is adjusted relative to the base 104, thereby affecting the accuracy of the angle adjustment of the shell 101, a first substrate 1042 and a second substrate 1043 are provided between the first substrate 1042 and the second substrate 1043. Figure 2 The counterweight 1044 is shown to increase the stability of the base 104. The bottom of the base 104 may also be provided with an anti-skid portion for preventing the base 104 from sliding, so as to further improve the stability of the base 104.

[0082] The third curved surface 1041 can be understood as the portion where the base 104 is connected to the housing 101, for example Figure 2 The portion of the substantially “U”-shaped groove indicated by reference numeral 1041 may have a curvature that is the same as that of the first curved surface 1013 and the second curved surface 1031 , so that the housing 101 can smoothly adjust its angle on the base 104 .

[0083] On this basis, in order to better adapt the connection between the third curved surface 1041 and the housing 101, the curvature of the connecting portion between the housing 101 and the third curved surface 1041 may be set to be the same as the curvature of the third curved surface 1041. Figure 2 As shown, the second guide member 105 is disposed on the third curved surface 1041. Figure 2The connection is shown on the third curved surface 1041 .

[0084] The second guide member 105 includes two parts, such as Figures 6 to 9 As shown, one part is a guide portion 1051 connected to the first guide member 103, and the other part is a connecting portion 1052 connected to the base 104. Under the action of the second guide member 105, an obstructing force (i.e., damping) that hinders the displacement of the shell 101 is generated between the guide portion 1051 and the first guide member 103. This obstructing force is greater than the moving force of the shell 101. Under the action of this obstructing force, the shell 101 will remain stable. The obstructing force may be the friction force between the guide portion 1051 and the first guide member 103, and may also include the friction force between the outer surface of the shell 101 and the third curved surface 1041. The moving force may include the gravity of the shell 101, the gravity of the electronic components in the chamber 102, and the like. The guide portion 1051 and the connecting portion 1052 in this embodiment may be an integral part, or may be formed as shown in FIG. Figures 6 to 9 Two separate pieces shown.

[0085] When applying the embodiment of the present disclosure, an external force can be applied to the shell 101. When the sum of the applied external force and the moving force of the shell 101 is greater than the hindering force, the shell 101 will be displaced along the angle adjustment path, thereby changing the adjustment angle of the shell 101. After the adjustment angle reaches the required level, the application of the external force is stopped. At this time, the moving force of the shell 101 is less than the hindering force, and the shell 101 remains stationary relative to the base 104, so that the shell 101 is temporarily fixed to the adjustment angle.

[0086] The shell 101 can be displaced along the angle adjustment path by means of the angle adjustment device, and the adjustment angle of the shell 101 relative to the base 104 can be flexibly changed and fixed according to shooting requirements.

[0087] In one embodiment, Figure 4 As shown, the portion of the first shell 1011 between the first guide 103 and the base 104 includes a first opening, and the portion of the second shell 1012 between the first guide 103 and the base 104 includes a second opening 10121, wherein after the first shell 1011 and the second shell 1012 are assembled, the first opening and the second opening 10121 form a first through hole 1014 in the first curved surface 1013. Figure 5 , Figure 6 As shown, the connecting portion 1052 of the second guide member 105 passes through the first through hole 1014 and is connected to the base 104, the first guide member 103 includes a guide groove 1032, and the guide portion 1051 of the second guide member 105 is inserted in the guide groove 1032 and abuts against the guide groove 1032 to provide an interference pre-pressure between the guide portion 1051 and the guide groove 1032 for forming damping.

[0088] The first through hole 1014 can be understood as a hole set on the shell 101 along the angle adjustment path, and its shape and size can be adapted to the guide groove 1032. During the displacement of the first guide member 103 along the angle adjustment path, the shell 101 will not hinder its displacement.

[0089] The guide portion 1051 of the second guide member 105 may be composed of two sections, such as Figure 6 As shown, one section is inserted into the slot of the guide groove 1032 to form a first interference pre-pressure, and the other section is against the upper side of the guide groove 1032 to form a second interference pre-pressure. The first interference pre-pressure is affected by the size of the guide portion 1051 of one section and the side wall of the slot of the guide groove 1032, so it is constant when the second guide member 105 is displaced along the angle adjustment path. The second interference pre-pressure is affected by the guide portion 1051 of the other section and the edge of the guide groove 1032, and it can be changed by changing the pressure applied to the guide portion 1051 of the other section. If the second interference pre-pressure is kept constant, the guide portion 1051 of the other section must be kept under constant applied pressure.

[0090] For example, in one embodiment, Figure 6 As shown, the connecting portion 1052 of the second guide member 105 is connected to the base 104 through the fastener 1045, and the connecting portion 1052 includes a step portion 10521, and the fastener 1045 abuts against the step portion 10521 to control the interference pre-pressure. During the connection process between the connecting portion 1052 and the fastener 1045, the guiding portion 1051 of the other section will move toward the fastener 1045 until they abut or squeeze each other, so as to generate the pressure of the second interference pre-pressure and continue to increase. After the step portion 10521 abuts against the fastener 1045, the connecting portion 1052 will not continue to move toward the fastener 1045, so that the distance between the connecting portion 1052 and the fastener 1045 reaches a fixed value, and the distance between the guiding portion 1051 of the other section and the edge of the guide groove 1032 is also fixed, so that the second interference pre-pressure generated by the two remains stable after reaching a certain value. By providing the step portion 10521 on the connecting portion 1052, when assembling multiple angle adjustment devices 100, the interference preload of the multiple angle adjustment devices 100 can be kept substantially consistent. Among them, the guide portion 1051 of one section and another section can be formed as a recess 10511, and the recess 10511 is clamped to the guide edge of the guide groove 1032. By providing the recess 10511 and the guide edge to match the shape, the interference preload is further kept constant along the angle adjustment path.

[0091] The fastener 1045 in the embodiment of the present disclosure may be a nut, the material of the nut may be copper, iron, alloy, etc., and the connecting portion 1052 of the second guide member 105 may be a screw. Fig. 9 Fig.10 , two recesses 10511 of different shapes are shown, which can be adapted to the guide edges of the first guide members 103 of different specifications.

[0092] In the above embodiment, the first guide member 103 may be connected only to the first shell 1011, or only to the second shell 1012, or connected to both the first shell 1011 and the second shell 1012. Figure 2 , Figure 3 , Figure 5 As shown, the first guide member 103 includes a first connecting wall 1034 connected to the first shell 1011 and a second connecting wall 1035 connected to the second shell 1012, and the first connecting wall 1034 is provided with a first accommodating portion 10341, which is configured to accommodate at least a portion of the guide portion 1051 when the second guide member 105 moves to the first connecting wall 1034 along the angle adjustment path.

[0093] The first accommodation portion 10341 can be understood as Figure 2 , Figure 3 , Figure 5 The groove-like structure arranged on the first connecting wall 1034 can be partially located in the first accommodating portion 10341 when the second guide member 105 moves along the angle adjustment path to abut against the first connecting wall 1034, so as to avoid the first connecting wall 1034 hindering the displacement of the second guide member 105, so as to maximize the increase in the length of the angle adjustment path and increase the adjustable angle of the angle adjustment device 100.

[0094] Based on the above embodiment, the first guide member 103 may further include a second accommodation portion 1033, which is disposed at the end of the guide groove 1032 adjacent to the second connecting wall 1035 (eg, Figure 5 As shown in the figure, the second accommodation portion 1033 is configured to accommodate at least a portion of the guide portion 1051 when the second guide member 105 moves to the end along the angle adjustment path. It can be understood that the second accommodation portion 1033 is arranged in a partial area of ​​the accommodation groove close to the second connecting wall 1035. When the second guide member 105 moves along the angle adjustment path to the end of the accommodation groove close to the second connecting wall 1035, part of the recess 10511 will be located in the second accommodation portion 1033 to prevent the second connecting wall 1035 from obstructing the displacement of the second guide member 105, so as to maximize the increase in the length of the angle adjustment path and increase the adjustable angle of the angle adjustment device 100. Similarly, the second accommodation portion 1033 can also be arranged at the end of the guide groove 1032 adjacent to the second connecting wall 1035 (as shown in the figure). Figure 5 shown).

[0095] In any of the above embodiments, the guide portion 1051 of the second guide member 105 is made of an elastic material to improve the wear resistance and aging resistance of the guide portion 1051. The elastic material may be silicone, rubber, plastic, or the like.
