Description

Technical Field

[0001] The present invention relates to a base and an image acquisition module, and particularly to a swivel base and an image acquisition module having the same. Background Art

[0002] Generally, outdoor monitors are more vulnerable to external impacts, which may cause damage to their structures. When using the IK10 impact test to simulate external forces, if the outdoor monitor has a relatively long housing, the rotating shaft of the outdoor monitor will be subjected to a stronger impact due to the relatively long lever arm, making the internal structure more likely to be damaged. The IK10 impact simulates the impact force generated by a 5-kilogram object falling from a height of 40 centimeters. Outdoor monitors on the market generally enhance the structural strength of the rotating shaft to improve the impact resistance. However, an overly strong structure may cause permanent damage to the structure due to the hard impact between structures. Therefore, how to reduce the probability of permanent damage to the internal structure of an outdoor monitor when it is subjected to external forces is a direction that the field is committed to exploring. Summary of the Invention

[0003] The present invention provides a swivel base and an image acquisition module, which can save configuration space and have better reliability.

[0004] A swivel base of the present invention includes a first housing, a second housing, a engaging member, and at least one elastic member. The first housing has a engaging structure. The second housing is rotatably connected to the first housing along a rotation axis. The engaging member is movably disposed in the second housing, wherein the engaging member is adapted to move to a first position in a first direction perpendicular to the rotation axis and engage with the engaging structure, and the engaging member is adapted to move to a second position in a second direction opposite to the first direction. At least one elastic member is disposed between the second housing and the engaging member and is adapted to provide an elastic force in the first direction, wherein the engaging member is positioned at the first position by the elastic force, and the engaging member is adapted to move to the second position against the elastic force by an external force from the second housing.

[0005] An image acquisition module of the present invention includes the above-mentioned swivel base and an image acquisition unit. The image acquisition unit is disposed on the first housing or the second housing.

[0006] In an embodiment of the present invention, the above-mentioned engaging structure includes a plurality of first tooth portions, the engaging member has at least one second tooth portion, and at least one second tooth portion is adapted to engage with a part of these first tooth portions.

[0007] In an embodiment of the present invention, the above-mentioned first tooth portions are arranged in a ring centered on the rotation axis.

[0008] In an embodiment of the present invention, the above-mentioned engaging member has at least one accommodating portion, and at least one elastic member is at least partially accommodated in at least one accommodating portion.

[0009] In an embodiment of the present invention, the above-mentioned at least one elastic member includes a plurality of elastic members.

[0010] In an embodiment of the present invention, the above-mentioned elastic members are arranged in a third direction perpendicular to the rotation axis.

[0011] In an embodiment of the present invention, the above-mentioned third direction is perpendicular to the first direction.

[0012] In an embodiment of the present invention, the above-mentioned steering base further includes a limiting member, wherein the limiting member is disposed on the second housing and prevents the engaging member from moving in a direction not parallel to the first direction.

[0013] In an embodiment of the present invention, the above-mentioned limiting member has a recess, and the engaging member at least partially slides in the recess along the first direction.

[0014] In an embodiment of the present invention, the movable range of the above-mentioned engaging member is greater than the engaging depth between the engaging member and the engaging structure.

[0015] Based on the above, in the steering base of the present invention, the engaging member disposed on the second housing is not completely fixedly engaged with the engaging structure of the first housing. Instead, the engaging member is engaged with the engaging structure by the elastic force of the elastic member and can be temporarily moved in a direction away from the engaging structure through the elastic deformation of the elastic member. Accordingly, when an external impact force acts on the second housing of the steering base, the impact force resists the elastic force of the elastic member to cause displacement of the engaging member, thereby temporarily releasing the complete engagement state between the engaging member and the engaging structure. Thus, the steering base of the present invention can avoid structural damage caused by forced relative movement when the engaging member and the engaging structure bear the impact force, thereby improving the reliability of the steering base. In addition, in the steering base structure of the present invention, the movable direction of the engaging member is perpendicular to the rotation axis of the steering base. Accordingly, the arrangement of the engaging member does not occupy the space of the steering base in the axial direction, so the steering base of the present invention can save the configuration space.

Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention. The same reference numerals will be used to represent the same or similar elements in all the drawings.

[0055] Figure 1 is a side view of an image acquisition module according to an embodiment of the present invention. Figure 2 is Figure 1 an exploded view of the steering base of. Please refer to Figure 1 and Figure 2 , the image acquisition module 10 of this embodiment is, for example, an outdoor monitor. The image acquisition module 10 includes a steering base 100 and an image acquisition unit 20. The image acquisition module 10 can acquire images of the external environment through the image acquisition unit 20. It should be noted that, Figure 1The image acquisition unit 20 is schematically shown in dashed lines and can actually be of other suitable shapes and sizes. The steering base 100 includes a first housing 110 and a second housing 120. The second housing 120 is rotatably connected to the first housing 110 along the rotation axis A, and the image acquisition unit 20 is disposed on the second housing 120. The user can adjust the position and angle of the image acquisition unit 20 by rotating the second housing 120 relative to the first housing 110. In other embodiments, the steering base 100 can be applied to other types of devices other than the image acquisition module, and the present invention does not limit this.

[0056] In addition, as Figure 1 shown, the steering base 100 further includes a fastener 170, such as a screw. The fastener 170 passes through the second housing 120 and is fastened to the first housing 110, so that the first housing 110 and the second housing 120 are fastened to each other in the direction parallel to the rotation axis A, and the second housing 120 can rotate relative to the first housing 110. On the other hand, in one embodiment, the first housing 110 and the second housing 120 are cylindrical structures and extend in a direction perpendicular to the rotation axis A. The first housing 110 is provided with a first mounting surface 112 ( Figure 2 ), and the second housing 120 is provided with a second mounting surface 122 ( Figure 2 ). The first mounting surface 112 and the second mounting surface 122 are correspondingly arranged. The first housing 110 is connected to the second mounting surface 122 of the second housing 120 through the first mounting surface 112. In this embodiment, the first mounting surface 112 and the second mounting surface 122 are respectively perpendicular to the rotation axis A. When the first housing 110 is fixed to the installation position, the adjustable angle of the second housing 120 is between +90 degrees and -90 degrees. For example, the direction of the rotation axis A is the Z-axis direction, the first housing 110 and the second housing 120 extend in the X-axis direction, and the second housing 120 can be adjusted relative to the first housing 110 between the positive Y-axis direction and the negative Y-axis direction.

[0057] In addition, in other embodiments, the image acquisition unit 20 can also be disposed on the first housing 110, so that the user can adjust the position and angle of the image acquisition unit 20 by rotating the first housing 110 relative to the second housing 120.

[0058] Figure 3 is Figure 1 a perspective view of the steering base. Figure 4 shown Figure 3 the movement of the engaging member. It should be noted that, in order to clearly show the internal structure of the steering base 100, Figure 3 and Figure 4 the second housing 120 in is shown in dashed lines.

[0059] Please refer to Figures 2 to 4, the steering base 100 of this embodiment further includes a clamping member 130 and a plurality of elastic members 140. The first mounting surface 112 of the first housing 110 has a clamping structure 111. The clamping member 130 is movably disposed on the second housing 120, and the elastic member 140 is disposed between the second housing 120 and the clamping member 130 and is adapted to provide an elastic force in a first direction D1 perpendicular to the rotation axis A. The clamping member 130 is adapted to move to the first position shown in Figure 3 by the elastic force in the first direction D1 and be clamped to the clamping structure 111, and be positioned at the first position by the elastic force. Moreover, the clamping member 130 is adapted to move to the second position shown in Figure 4 by an external force from the second housing 120 in a second direction D2 opposite to the first direction D1.

[0060] In this embodiment, the clamping member 130 is disposed at one end of the second housing 120 close to the first housing 110, that is, as shown in Figure 3 and Figure 4 it is located on the right side of the clamping structure 111, but the present invention does not limit the position of the clamping member 130 disposed in the clamping structure 111.

[0061] As described above, in the steering base 100 of this embodiment, the clamping member 130 disposed on the second housing 120 is not completely fixedly clamped to the clamping structure 111 of the first housing 110. Instead, the clamping member 130 is clamped to the clamping structure 111 by the elastic force of the elastic member 140 and can be temporarily moved in a direction away from the clamping structure 111 through the elastic deformation of the elastic member 140. Accordingly, when an external impact force acts on the second housing 120 of the steering base 100, the impact force resists the elastic force of the elastic member 140 to cause the clamping member 130 to displace, and then temporarily releases the complete clamping state between the clamping member 130 and the clamping structure 111. Thus, the steering base 100 of this embodiment can avoid structural damage caused by forced relative movement when the clamping member 130 and the clamping structure 111 bear the impact force, thereby improving the reliability of the steering base 100. In addition, in the structure of the steering base 100 of this embodiment, the movable direction of the clamping member 130 is perpendicular to the rotation axis A of the steering base 100. Accordingly, the setting of the clamping member 130 does not excessively occupy the space of the steering base 100 in the axial direction, so the steering base 100 of this embodiment can save the configuration space.

[0062] In this embodiment, the number of the elastic members 140 can be multiple, for example, three, but the number of the elastic members 140 is not limited thereto. Moreover, these elastic members 140 are arranged in a third direction D3 perpendicular to the rotation axis A as shown in Figure 3 . The third direction D3 is perpendicular to the first direction D1.

[0063] The specific structure of the steering base 100 of this embodiment will be described in more detail below.

[0064] Figure 5A is Figure 2 a perspective view of the engaging member. Figure 5B is Figure 5A a perspective view of the engaging member from another perspective. Please refer to Figure 5A and Figure 5B , the engaging member 130 has a plurality of accommodating portions 132. As Figure 3 shown, a part of these elastic members 140 is accommodated in the accommodating portions 132, and the other ends of these elastic members 140 are connected to a surface 121 of the second housing 120. In this embodiment, the number of the accommodating portions 132 is three, but the number of the accommodating portions 132 is not limited thereto. In addition, the engaging member 130 further has a plurality of ribs 133, and these ribs 133 extend parallel to the movable direction (i.e., the first direction D1 and the second direction D2) of the engaging member 130. The engaging member 130 is in contact with the second housing 120 through these ribs 133 to reduce the frictional force between the engaging member 130 and the second housing 120. In this embodiment, the number of the ribs 133 is four, but the number of the ribs 133 is not limited thereto.

[0065] Figure 6 is Figure 2 a partial enlarged view of the first housing. Please refer to Figure 5A and Figure 6 , the engaging structure 111 of the first housing 110 includes a plurality of first tooth portions 1111, and these first tooth portions 1111 are arranged annularly around the rotation axis A. The engaging member 130 has a plurality of second tooth portions 131, and these second tooth portions 131 are adapted to engage with a part of these first tooth portions 1111. When the engaging member 130 is in the first position as Figure 3 shown, a part of these first tooth portions 1111 engages with these second tooth portions 131 to fix the relative angle between the first housing 110 and the second housing 120.

[0066] In this embodiment, the number of the second tooth portions 131 is five, but the number of the second tooth portions 131 is not limited thereto.

[0067] Furthermore, in the steering base 100 of the present embodiment, the number of the second teeth 131 of the engaging member 130 is less than the number of the first teeth 1111 of the engaging structure 111, and the second teeth 131 are only engaged with a part of the first teeth 1111. Accordingly, the engaging member 130 and its second teeth 131 have a smaller volume. Moreover, the engaging member 130 is at least partially disposed in the existing space surrounded by the annular first teeth 1111 and acts in a direction perpendicular to the rotation axis A (the first direction D1 and the second direction D2). Therefore, it is possible to avoid over-occupying the axial space of the steering base 100 as described above, which is beneficial to reducing the volume of the steering base 100.

[0068] Figure 7 Yes Figure 1 Partial sectional view of another section of the steering base. Figure 8 Illustrate Figure 7 The movement of the engaging member. Please refer to Figure 2 , Figure 7 And Figure 8 , the steering base 100 further includes a limiting member 150. The limiting member 150 is disposed on the second housing 120 and is fastened to the second housing 120 by two fasteners 160 (such as screws). In addition, the central section of the limiting member 150 has a recess 151, and a part of the engaging member 130 slides in the recess 151 along the first direction D1. Such a design limits the engaging member 130 between the second housing 120 and the limiting member 150 in a direction parallel to the rotation axis A, thereby preventing the engaging member 130 from moving in a direction not parallel to the first direction D1 and / or the second direction D2 (such as a direction parallel to the rotation axis A).

[0069] In the present embodiment, the limiting member 150 is a U-shaped structure, and through holes are provided at both ends for the two fasteners 160 to pass through, but the shape of the limiting member 150 and the position of the through holes are not limited thereto.

[0070] In addition, as Figure 3 shown, the movable range R of the engaging member 130 of the present embodiment is greater than the engaging depth S between the engaging member 130 and the engaging structure 111. Accordingly, it can be ensured that in the Figure 4 shown state, the meshing amount between the first teeth 1111 and the second teeth 131 will decrease, and even, there is no meshing amount between the first teeth 1111 and the second teeth 131. Furthermore, it is possible to indeed avoid structural damage caused by forced relative movement when the engaging member 130 and the engaging structure 111 bear impact force as described above.

[0071] It should be noted that when the meshing amount between the second teeth 131 and the first teeth 1111 decreases and the engaging member 130 rotates relative to the engaging structure 111, one surface 1311 of the second teeth 131 ( Figure 5A) is still in contact with a surface 1112 of the first tooth portion 1111 of the engaging structure 111. Figure 6 ) still have contact with each other.

[0072] In summary, in the steering base of the present invention, the engaging member provided on the second housing is not completely fixedly engaged with the engaging structure of the first housing. Instead, the engaging member is engaged with the engaging structure by the elastic force of the elastic member and can be temporarily moved in a direction away from the engaging structure through the elastic deformation of the elastic member. Accordingly, when an external impact force is applied to the second housing of the steering base, the impact force resists the elastic force of the elastic member to cause displacement of the engaging member, thereby temporarily releasing the complete engagement state between the engaging member and the engaging structure. Thus, the steering base of the present invention can avoid structural damage caused by forced relative movement when the engaging member and the engaging structure bear the impact force, thereby improving the reliability of the steering base. In addition, in the steering base structure of the present invention, the movable direction of the engaging member is perpendicular to the rotation axis of the steering base. Accordingly, the setting of the engaging member does not occupy the space of the steering base in the axial direction, so the steering base of the present invention can save the configuration space.

[0073] Although the technical content of the present invention has been disclosed above in preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art, without departing from the spirit of the present invention, makes some modifications and refinements, and all should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the appended claims.
