[0035] When clamping a mobile phone, the brackets currently on the market require multiple steps to place the mobile phone on the bracket in a specific posture, and then the bracket clamps the mobile phone in the specific posture. In this process, the operation steps are relatively cumbersome, and only the mobile phone in a specific posture can be clamped, which cannot meet the user's usage needs in different scenarios.
[0036] The present application provides a bracket capable of clamping objects in different positions. Figure 1 , Figure 2 , Figure 3 Figure 4 and Figure 5 ; Figure 1 The overall structure of the bracket is shown. Figure 2 An exploded view of the bracket is shown. Figure 3 The figure shows a state in which the support holds the clamped object 5 in the first position. Figure 4 The structure diagram of the cover body 12 is shown. Figure 5 The structure diagram of the body 11 is shown. The bracket capable of clamping objects in different positions includes: a base 1, a support member 2 and a clamping assembly 3; wherein the support member 2 is movably arranged on the base 1 for supporting the clamped object 5; the clamping assembly 3 has a first clamping portion 31 and a second clamping portion 32, the first clamping portion 31 is movably connected to the base 1, the support member 2 is connected to the first clamping portion 31, and the first clamping portion 31 is connected to the second clamping portion 32; the distance between the first clamping portion 31 and the base 1 is a first distance, the distance between the second clamping portion 32 and the base 1 is a second distance, and the first distance is greater than the second distance; when the support member 2 is subjected to the force of the clamped object 5, the support member 2 drives the clamping assembly 3 to move relative to the base 1, so as to clamp the clamped object 5 in the first position through the first clamping portion 31, or to clamp the clamped object 5 in the second position through the second clamping portion 32.
[0037] In the embodiment of the present application, the base 1 can provide support for the support member 2, and the base 1 can also provide support for a part of the structure of the clamping assembly 3. For example, the base 1 has a structure that can provide a mounting point for the support member 2; for another example, the base 1 has a structure that matches a part of the structure of the clamping assembly 3. The support member 2 is mounted on the base 1 through the corresponding structures on the base 1 and the support member 2, and the clamping assembly 3 and the base 1 are connected through the matching structure between the base 1 and the clamping assembly 3.
[0038] Exemplarily, the base 1 can be a box body. Taking the case where the base 1 is a box body, the box body includes a body 11 and a cover body 12, and the body 11 and the cover body 12 are respectively provided with a matching first covering structure and a second covering structure, and the body 11 is covered with the cover body 12 through the first covering structure and the second covering structure, and a receiving space is formed after the body 11 and the cover body 12 are covered, and the receiving space has a structure matching the support member 2, a part of the support member 2 can be installed in the receiving space, and a part of the clamping assembly 3 can be installed in the receiving space.
[0039] Among them, a guide column can be provided on the main body 11, and a guide groove matching the guide column can be provided on the support member 2. The size of the guide column can match the size of the guide column, the shape of the guide column can match the shape of the guide groove, and the guide column can slide in the guide groove, so that the support member 2 can slide on the main body 11.
[0040] Furthermore, a connecting groove may be provided on the main body 11, and the clamping assembly 3 may have a structure that can match the connecting groove, so that a part of the clamping assembly 3 can slide in the connecting groove, thereby allowing the clamping assembly 3 to slide in the connecting groove as the support member 2 moves.
[0041] As another example, the base 1 has a structure or part that can install the base 1 on the object to be installed. For example, the base 1 has an internal thread, and a mounting piece is provided on the object to be installed. The mounting piece has an external thread that matches the internal thread. The base 1 can be screwed into the mounting piece through the internal thread and the external thread, so that the bracket is installed on the object to be installed.
[0042] Alternatively, a mounting piece is provided at a position on the base 1 that is pre-connected with the object to be installed, the mounting piece has an external thread, a mounting hole is provided on the object to be installed, and the mounting hole has an internal thread matching the external thread. The base 1 can be screwed into the mounting hole through the external thread and the internal thread, thereby connecting the bracket and the object to be installed.
[0043] As another example, Velcro or other adhesives with adhesion function may be provided on the base 1, and the base 1 may be mounted on the object to be mounted through the adhesive, thereby fixing the bracket on the object to be mounted.
[0044] In the embodiment of the present application, the support member 2 may be provided with a structure matching the clamped object 5, and the support member 2 provides support to the clamped object 5 through the structure, so that the clamped object 5 can be placed on the bracket. In addition, the support member 2 is provided with a structure matching the clamping assembly 3, so that the support member 2 can be connected to the clamping assembly 3, and the movement of the support member 2 drives the clamping assembly 3 to move relative to the base 1.
[0045] For example, a curved surface is provided at the position where the support 2 and the clamped object 5 are in contact, and the clamped object 5 can be more closely contacted with the support 2 through the curved surface. When the support 2 moves under the force of the clamped object 5, the probability of the clamped object 5 shaking too much during the movement of the support 2 is reduced, and the stability of the clamped object 5 during the movement is improved.
[0046] In another example, the support member 2 may be provided with a blocking portion, which may be connected to the support member 2 by common parts such as screws, or may be integrally formed with the support member 2. The blocking portion is used to reduce the probability of the clamped object 5 falling from the support member 2.
[0047] In another example, an active structure is provided on the support member 2, and a driven structure adapted to the active structure is provided on the clamping assembly 3. The support member 2 is connected to the clamping assembly 3 through the active structure and the driven structure, so that the support member 2 can drive the clamping assembly 3 to move. For example, a convex shaft is provided on the support member 2, and a connecting groove is provided at the corresponding position of the clamping assembly 3 and the support member 2. When the support member 2 moves, the convex shaft can move in the connecting groove, thereby driving the clamping assembly 3 to move relative to the base 1. For another example, a movable part is provided between the support member 2 and the clamping assembly 3, one end of the movable part is connected to the support member 2, and the other end is connected to the clamping assembly 3. The support member 2 can drive the clamping assembly 3 to move relative to the base 1 through the movable part.
[0048] In the embodiment of the present application, the clamping assembly 3 can be configured to include a first clamping portion 31 and a second clamping portion 32. The first clamping portion 31 is connected to the support member 2, and the first clamping portion 31 can move on the base 1. In this configuration, when the support member 2 moves, the first clamping portion 31 can be driven to move relative to the base 1; the second clamping portion 32 is connected to the first clamping portion 31, and the first clamping portion 31 can drive the second clamping portion 32 to move during the movement of the support member 2 relative to the base 1.
[0049] The distance between the first clamping part 31 and the base 1 is set as the first distance, the distance between the second clamping part 32 and the base 1 can be set as the second distance, and the first distance can be greater than the second distance. When the support member 2 is subjected to the force of the clamped object 5, the support member 2 can drive the first clamping part 31 to move relative to the base 1, and the second clamping part 32 to move during the movement of the first clamping part 31; the clamped object 5 in the first posture is clamped by the first clamping part 31, or the clamped object 5 in the second posture is clamped by the second clamping part 32.
[0050] For example, the first clamping portion 31 and the second clamping portion 32 will not deform. The second clamping portion 32 can be detachably connected to the first clamping portion 31, or the second clamping portion 32 can be connected to the first clamping portion 31 in an integrally formed manner.
[0051] As another example, in the case where the first clamping portion 31 and / or the second clamping portion 32 can deform under the action of a force, the first clamping portion 31 can be bent to clamp the clamped object 5 in the first position; or the second clamping portion 32 can be bent to clamp the clamped object 5 in the second position.
[0052] Among them, take the clamped object 5 as an example, which is a mobile phone. The clamped object 5 in the first posture can correspond to the horizontal screen state of the mobile phone, that is, the mobile phone in the horizontal screen state can be clamped by the first clamping part 31; the clamped object 5 in the second posture can correspond to the vertical screen state of the mobile phone, that is, the mobile phone in the vertical screen state can be clamped by the second clamping part 32. The bracket provided in this application can clamp mobile phones with a size within the range of 130-175mm, and can also clamp mobile phones with a size within the range of 60-80mm. The size of the clamped object 5 is not limited in the embodiment of this application.
[0053] In the above embodiment, the support member 2 can provide support for the clamped object 5. When the support member 2 is subjected to the force of the clamped object 5, the support member 2 can drive the clamping assembly 3 to slide on the base 1, so as to adjust the distance between the first clamping portion 31 in the clamping assembly 3 and the base 1, and clamp the clamped object 5 in the first posture through the first clamping portion 31; or, while the first clamping portion 31 moves, the distance between the second clamping portion 32 and the base 1 can be adjusted, and the clamped object 5 in the second posture can be clamped through the second clamping portion 32. The user places the clamped object 5 on the support member 2, and the clamped object 5 can be clamped by the first clamping portion 31 or the second clamping portion 32, and the operation steps are simple; at the same time, compared with only being able to clamp the clamped object 5 in a specific posture, the first clamping portion 31 and the second clamping portion 32 can clamp the clamped object 5 in different postures, so as to meet the user's needs of using the clamped object 5 in different scenarios.
[0054] In some embodiments of the present application, reference Figure 6 , Figure 6 FIG. 3 shows a connection structure diagram of the connecting member 33 and the first clamping portion 31. Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the support member 2 is slidably disposed on the base 1 along the first direction A, and the first clamping portion 31 is extended along the second direction B; when the support member 2 is subjected to the force of the clamped object 5, the support member 2 drives the first clamping portion 31 to slide along the second direction B on the base 1.
[0055] In the embodiment of the present application, the support member 2 can be set to a structural form that slides on the base 1 along the first direction A. The first clamping portion 31 can be formed by extending along the second direction B, and the second direction B can be a direction away from the base 1. When the support member 2 is subjected to the force of the clamped object 5, the support member 2 moves along the first direction A in a direction away from the base 1, and the support member 2 drives the first clamping portion 31 to move, and the first clamping portion 31 moves along the second direction B on the base 1 in a direction away from the base 1.
[0056] For example, Figure 1 and Figure 4 As shown, a first support groove 121 is provided on the base 1, and the first support groove 121 is extended along the first direction A. For example, the first support groove 121 can be a square straight groove, and the cross-section of the contact position between the support member 2 and the first support groove 121 is set to a shape matching the first support groove 121 so that the support member 2 can slide in the first support groove 121.
[0057] Another example, such as Figure 4 As shown, the base 1 is provided with a second support groove 122, which is formed by extending along the second direction B. The second support groove 122 can also be a square straight groove. The cross section of the contact position between the first clamping portion 31 and the second support groove 122 in the clamping assembly 3 can be set to a shape that can match the second support groove 122, so that the first clamping portion 31 can slide in the second support groove 122 driven by the support member 2. It can be understood that there is an angle between the extension direction of the first support groove 121 and the extension direction of the second support groove 122.
[0058] Another example, Figure 6As shown, a connecting member 33 may be provided between the first clamping portion 31 and the support member 2, one end of the connecting member 33 being connected to the support member 2, and the other end being connected to the first clamping portion 31. For example, one end of the connecting member 33 may be rotatably connected or slidably connected to the support member 2, and the other end of the connecting member 33 and one of the first clamping portion 31 may have a waist-shaped hole 313, the waist-shaped hole 313 being a long strip-shaped through hole, the length of which is greater than the width, and the waist-shaped hole 313 may be used to connect two plates or parts. A connecting rod 331 may be provided on the other of the first clamping portion 31 and the connecting member 33, the shape of the connecting rod 331 matching the shape of the waist-shaped hole 313, so that the connecting rod 331 can be inserted into the waist-shaped hole 313, and when the support member 2 drives the connecting member 33 to move, the connecting rod 331 moves in the waist-shaped hole 313 along with the movement of the connecting member 33, thereby driving the first clamping portion 31 to slide on the base 1.
[0059] It needs to be explained that Figure 5 As shown, one of the base 1 and the connecting member 33 may be provided with an inclined groove 111, and correspondingly, the other of the base 1 and the connecting member 33 may be provided with a guide shaft matching the inclined groove 111. The inclined groove 111 extends along the third direction C, and when the support member 2 drives the connecting member 33 to move, the guide shaft can slide in the inclined groove 111 along with the movement of the connecting member 33. There is an angle between any two of the first direction A, the second direction B and the third direction C to reduce the probability of interference between them, and the angle can be 30° or 45°, etc., that is, the support member 2 can drive the first clamping portion 31 to move through the connecting member 33.
[0060] And, if Figure 2 As shown, a reset member 4 can also be arranged between the support member 2 and the base 1, with one end of the reset member 4 connected to the base 1 and the other end connected to the support member 2. The support member 2 can apply a force to the reset member 4 away from the base 1, or the reset member 4 can apply a force to the support member 2 toward the base 1 to reset the reset member 4.
[0061] In the above embodiment, since the support member 2 is configured to be able to move along the first direction A on the base 1, and since the first clamping portion 31 is configured to be able to move along the second direction B on the base 1, when the clamped object 5 is placed on the support member 2 and the support member 2 is subjected to the force of the clamped object 5, the support member 2 can drive the first clamping portion 31 to move, thereby clamping the clamped object 5 through the first clamping portion 31, and the operation steps are simple.
[0062] In some embodiments of the present application, reference Figure 7 , Figure 7 FIG. 4 shows a state in which the support holds the object 5 in the second position. Figure 1 , Figure 3 and Figure 7 As shown, the second clamping portion 32 is formed by extending from the first clamping portion 31 in a direction away from the support member 2 , or the second clamping portion 32 is formed by extending from the first clamping portion 31 along the second direction B.
[0063] In the embodiment of the present application, the second clamping portion 32 may be formed by extending from the first clamping portion 31. For example, the extension direction of the second clamping portion 32 is a direction away from the support member 2;
[0064] Exemplarily, the second clamping portion 32 may be formed to extend along the first direction A from the first clamping portion 31 in a direction away from the support member 2 .
[0065] In another example, the second clamping portion 32 may be formed to extend along the second direction B from the first clamping portion 31 in a direction away from the base 1 .
[0066] In another example, the second clamping portion 32 may be formed to extend along any direction within the range defined by the first direction A and the second direction B.
[0067] In the above embodiment, the second clamping portion 32 is provided as a structure extending from the first clamping portion 31, so that the user can clamp the clamped object 5 in the first position through the first clamping portion 31, or clamp the clamped object 5 in the second position through the second clamping portion 32. No other complex structures are provided on the first clamping portion 31 or the second clamping portion 32, which is convenient for operation.
[0068] In some embodiments of the present application, the first clamping portion 31 and the second clamping portion 32 are respectively provided with a first connection structure and a second connection structure that match each other, and the second clamping portion 32 is detachably placed on the first clamping portion 31 through the first connection structure and the second connection structure. Alternatively, the second clamping portion 32 and the first clamping portion 31 are integrally formed.
[0069] In the embodiment of the present application, a first connecting structure can be set on the first clamping portion 31, and a second connecting structure can be set on the second clamping portion 32. The first connecting structure and the second connecting structure match each other. The second clamping portion 32 is connected to the first clamping portion 31 through the first connecting structure and the second connecting structure, and can be removed from the first clamping portion 31.
[0070] Exemplarily, threaded holes are provided on the first clamping portion 31 and the second clamping portion 32 , and the second clamping portion 32 is detachably connected to the first clamping portion 31 by screwing bolts into the threaded holes.
[0071] In another example, an adhesive may be provided on one of the first clamping portion 31 and the second clamping portion 32 , and the second clamping portion 32 is adhered to the first clamping portion 31 by the adhesive, and the second clamping portion 32 can be removed from the first clamping portion 31 .
[0072] In another example, the second clamping portion 32 may be integrally formed with the first clamping portion 31. That is, the first clamping portion 31 and the second clamping portion 32 exist as a whole.
[0073] In the above embodiment, since the second clamping part 32 is detachably connected to the first clamping part 31, on the one hand, it is convenient to replace the second clamping part 32 to meet the requirements of clamping objects 5 of different sizes; on the other hand, the position of the second clamping part 32 relative to the clamped object 5 can be adjusted to fit more closely with the clamped object 5, thereby increasing the probability of clamping the clamped object 5. Since the second clamping part 32 and the first clamping part 31 are integrally formed and manufactured, it is not necessary to adjust the second clamping part 32 or the first clamping part 31 separately, thereby reducing the number of operation steps.
[0074] In some embodiments of the present application, one of the first clamping portion 31 and the second clamping portion 32 has a first slide groove, and the other has a slider adapted to the first slide groove, the first slide groove extends along the first direction A, and the slider slides in the first slide groove to slidably connect the second clamping portion 32 with the first clamping portion 31; along the first direction A, the second clamping portion 32 can clamp the clamped object 5 away from the side of the support member 2.
[0075] In the embodiment of the present application, one of the first clamping portion 31 and the second clamping portion 32 may be provided with a first slide groove, and the other may be provided with a slider, which can be inserted into the first slide groove and slide in the first slide groove. The first slide groove can be formed by extending along the first direction A, that is, the extension direction of the first slide groove is parallel to, or nearly parallel to, the sliding direction of the support member 2 on the base 1. The second clamping portion 32 can slide on the first clamping portion 31 by sliding the slider in the first slide groove. Along the sliding direction of the second clamping portion 32, the second clamping portion 32 can clamp the clamped object 5 away from the side of the support member 2, that is, the second clamping portion 32 can clamp the upper and middle part of the clamped object 5 in the second posture to enhance the clamping effect on the clamped object 5.
[0076] Exemplarily, a first slide groove is provided on the first clamping portion 31, and the first slide groove extends along the first direction A; a slider is provided on the second clamping portion 32, and the slider can slide in the first slide groove so that the second clamping portion 32 can slide along the first direction A on the first clamping portion 31.
[0077] In another example, a guide block is provided on the first clamping portion 31, and a first slide groove is provided on the second clamping portion 32, the first slide groove extends along the first direction A, and the second clamping portion 32 is able to slide on the first clamping portion 31 under the action of the guide block and the first slide groove.
[0078] The second clamping portion 32 may also slide on the first clamping portion 31 along other directions, for example, the angle between the direction and the first direction A may be 30°, 40° or 50°, etc., as long as the first clamping portion 31 is not affected in clamping the clamped object 5 in the first posture, and the second clamping portion 32 is not affected in clamping the clamped object 5 in the second posture.
[0079] It should be explained that the second clamping portion 32 can be connected to the first clamping portion 31 by interference fit, or a limit member can be provided between the second clamping portion 32 and the first clamping portion 31 to reduce the probability of the second clamping portion 32 slipping off the first clamping portion 31 when clamping the clamped object 5.
[0080] In the above embodiment, since the first slide groove and the slider are provided, the second clamping portion 32 can move on the first clamping portion 31 through the first slide groove and the slider. Taking the second clamping portion 32 on the first clamping portion 31 along the first direction A as an example, by adjusting the position of the second clamping portion 32 in the first direction A, the clamped objects 5 with different sizes in the first direction A can be clamped.
[0081] In some embodiments of the present application, a damping structure is provided at a position on the first clamping portion 31 corresponding to a position on the second clamping portion 32 , and the second clamping portion 32 is rotatably connected to the first clamping portion 31 via the damping structure.
[0082] In the embodiment of the present application, a damping structure may be provided on the first clamping portion 31 or the second clamping portion 32, and the second clamping portion 32 is rotatably connected to the first clamping portion 31 through the damping structure. That is, the second clamping portion 32 rotates on the first clamping portion 31 through the damping structure, so as to adjust the position of the second clamping portion 32 on the first clamping portion 31.
[0083] Exemplarily, a damping structure is installed on the side of the first clamping portion 31 away from the support member 2, the second clamping portion 32 is rotatably connected to the first clamping portion 31 through the damping structure, and the second clamping portion 32 rotates on the first clamping portion 31 with the second direction B as the axis.
[0084] As another example, along the first direction A, a damping structure may be installed on a side of the second clamping portion 32 close to the first clamping portion 31 , so that the second clamping portion 32 rotates on the first clamping portion 31 with the second direction B as an axis.
[0085] It needs to be explained that the principle of the damping structure is to generate friction through the extrusion between gaskets. Under the action of friction, one of the two parts connected by the damping structure can be maintained in a specific position. The magnitude of the friction force is related to the number of gaskets installed and the tightness of the nuts.
[0086] Among them, the damping structure can be divided into a connecting shaft, a connecting plate, a gasket and a nut. The connecting shaft provides an installation environment for the connecting plate, the gasket and the nut. The connecting plate, the gasket and the nut are sleeved on the connecting shaft, and the connecting plate is located between the gasket and the nut. The connecting shaft has a threaded structure that is adapted to the nut, and the nut can move on the connecting shaft. The nut is turned in the direction close to the connecting plate so that the nut squeezes the connecting plate and the connecting plate squeezes the gasket. The second clamping portion 32 mentioned above rotates on the first clamping portion 31 with the second direction B as the axis, which can be understood as the axis of the connecting shaft in the damping structure being parallel to the second direction B, or nearly parallel.
[0087] In the above embodiment, since a damping structure is provided, when in use, the clamped object 5 can be extended through the provided damping structure, and the position of the second clamping portion 32 relative to the clamped object 5 can be adjusted so as to clamp the clamped object 5 from different positions; when not in use, the second clamping portion 32 can also be retracted to reduce the space occupied by the bracket.
[0088] In some embodiments of the present application, reference Figure 8 , Figure 8 The diagram shows the connection structure of the first clamping portion 31 and the second clamping portion 32. The first clamping portion 31 includes a second slide groove 311, which is formed to extend along the second direction B. The second clamping portion 32 slides in the second slide groove 311 to slide the second clamping portion 32 to the first clamping portion 31; along the second direction B, the second clamping portion 32 can clamp the clamped object 5 away from the side of the base 1.
[0089] In the embodiment of the present application, the first clamping portion 31 may be provided with a second slide groove 311, and the second slide groove 311 may be formed by extending along the second direction B, that is, the extension direction of the second slide groove 311 is parallel or nearly parallel to the sliding direction of the first clamping portion 31 on the base 1. The second clamping portion 32 can slide on the second slide groove 311. Along the sliding direction of the second clamping portion 32, the second clamping portion 32 can clamp the clamped object 5 away from the side of the base 1, and the second clamping portion 32 can clamp the upper and middle part of the clamped object 5 in the second posture to enhance the clamping effect on the clamped object 5.
[0090] Exemplarily, a connecting block 321 is installed on the second clamping portion 32, or a connecting block 321 is integrally formed on a side of the second clamping portion 32 close to the first clamping portion 31, and the connecting block 321 can slide in the second slide groove 311, and the second clamping portion 32 is slidably connected to the first clamping portion 31 through the connecting block 321.
[0091] In another example, a portion of the second clamping portion 32 can slide in the second sliding groove 311 , and an end of the second clamping portion 32 away from the base 1 can clamp the clamped object 5 .
[0092] Alternatively, the second clamping portion 32 may slide on the first clamping portion 31 along other directions, for example, the angle between the direction and the second direction B may be 15°, 20° or 30°, that is, the angle between the second slide groove 311 and the second direction B may be 15°, 20° or 30°, etc. It is sufficient that the first clamping portion 31 is not affected in clamping the clamped object 5 in the first posture, and the second clamping portion 32 is not affected in clamping the clamped object 5 in the second posture.
[0093] It should be explained that the second clamping portion 32 can be connected to the first clamping portion 31 by interference fit, or a limit member can be provided between the second clamping portion 32 and the first clamping portion 31 to reduce the probability of the second clamping portion 32 slipping off the first clamping portion 31 when clamping the clamped object 5.
[0094] In the above embodiment, due to the provision of the second slide groove 311, the second clamping portion 32 can move relative to the clamped object 5 on the first clamping portion 31 through the provision of the second slide groove 311. Taking the movement of the second clamping portion 32 on the first clamping portion 31 along the second direction B as an example, by adjusting the position of the second clamping portion 32 on the first clamping portion 31, the clamped objects 5 with different sizes in the second direction B can be clamped, thereby expanding the applicable range of the bracket.
[0095] In some embodiments of the present application, reference Fig. 9 and Fig.10 , Fig. 9 The flexible fixing member 322 is shown in a state where it is not bent. Fig.10 The second clamping portion 32 includes a flexible fixing member 322, the connection end of which is connected to the first clamping portion 31, at least a portion of the flexible fixing member 322 close to the connection end can be deformed, and the fixed end of the flexible fixing member 322 can be bent in a direction away from the first clamping portion 31.
[0096] In the embodiment of the present application, the second clamping portion 32 may be configured to include a flexible fixing member 322. The flexible fixing member 322 may include a fixed end and a connecting end, wherein the connecting end of the flexible fixing member 322 may be connected to the first clamping portion 31, so that at least a portion of the flexible fixing member 322 close to the connecting end may be deformed, or all portions of the flexible fixing member 322 close to the connecting end may be deformed; the fixed end of the flexible fixing member 322 may be bent in a direction away from or close to the first clamping portion 31, and the clamped object 5 in different postures may be clamped by the flexible fixing member 322 or the first clamping portion 31.
[0097] Exemplarily, an avoidance groove 312 can be provided on the first clamping portion 31, and the direction of the avoidance groove 312 extends along the second direction B; along the second direction B, the size of the flexible fixing member 322 can be smaller than the size of the avoidance groove 312, or can be the same as, or nearly the same as, the size of the avoidance groove 312; the avoidance groove 312 has a guiding effect on the flexible fixing member 322, and the flexible fixing member 322 can move in the avoidance groove 312 to be on the same plane as the first clamping portion 31, so as to reduce the probability of interference between the flexible fixing member 322 and the clamped object 5, so that the first clamping portion 31 can clamp the clamped object 5 in the first posture.
[0098] As another example, the flexible fixing member 322 may be directly connected to the first clamping portion 31 . When the flexible fixing member 322 is bent into a plane, the flexible fixing member 322 may not be on the same plane as the first clamping portion 31 , so as not to affect the first clamping portion 31 clamping the clamped object 5 .
[0099] In another example, the connection end of the flexible fixing member 322 can be integrally formed with the first clamping portion 31, and the fixed end of the flexible fixing member 322 can be bent in a direction close to or away from the first clamping portion 31; or, the flexible fixing member 322 is a separate part, and the connection end can be connected to the first clamping portion 31 by bonding, screw connection, etc. That is, the connection end of the flexible fixing member 322 can remain stationary, and the fixed end can be bent in a direction close to or away from the first clamping portion 31.
[0100] It should be noted that the flexible fixing member 322 may be deformed when subjected to an external force. When the external force disappears, the flexible fixing member 322 will not return to its original state and may be suspended at a specific position, thereby clamping the clamped object 5 .
[0101] In the above embodiment, since a flexible fixing member 322 is provided, the clamped object 5 in the second posture can be clamped by the flexible fixing member 322; the flexible fixing member 322 can be connected to the first clamping portion 31, which can save space and simplify the structure. By bending the flexible fixing member 322, the clamped object 5 can be clamped.
[0102] In some embodiments of the present application, the flexible fixing member 322 and the first clamping portion 31 are both made of flexible material, and the flexible fixing member 322 and the first clamping portion 31 are integrally formed.
[0103] In the embodiment of the present application, the flexible fixing member 322 and the first clamping portion 31 can both be supported by a flexible material, and the flexible material can be deformed in the direction of the force when subjected to an action force, and can remain in the deformed state after the action force disappears. The flexible fixing member 322 can be integrally formed with the first clamping portion 31, that is, the flexible fixing member 322 and the first clamping portion 31 are formed as a whole without being connected by other parts.
[0104] For example, when a force is applied to the flexible fixing member 322, it can be deformed along the first direction A on the first clamping portion 31, or along the second direction B; or it can be deformed along other directions. The deformed flexible fixing member 322 can be used to clamp the clamped object 5 in the second posture.
[0105] In another example, when the first clamping portion 31 is made of a flexible material, when the first clamping portion 31 is subjected to a force, the first clamping portion 31 may be deformed along the first direction A, or along the second direction B; or may be deformed along other directions. The deformed first clamping portion 31 may be used to clamp the clamped object 5 in the first position.
[0106] As another example, the first clamping portion 31 may not be made of flexible material, and the end of the first clamping portion 31 away from the base 1 has a structure that can match the clamped object 5, such as a slot, a claw or other structures or parts that can clamp the clamped object 5.
[0107] In the above embodiment, the flexible fixing member 322 and the first clamping portion 31 are both made of flexible materials and are integrally formed, which is convenient for production and manufacturing, and can improve the tightness of contact between the flexible fixing member 322 or the first clamping portion 31 and the clamped object 5, thereby improving the fixing effect of the clamped object 5.
[0108] In some embodiments of the present application, a matching third connection structure and a fourth connection structure are respectively provided between the first clamping portion 31 and the flexible fixing member 322, and the first clamping portion 31 is connected to the flexible fixing member 322 via the third connection structure and the fourth connection structure.
[0109] In an embodiment of the present application, a third connection structure may be provided on the first clamping portion 31, and a fourth connection structure may be provided on the flexible fixing member 322, and the third connection structure and the fourth connection structure match, that is, the first clamping portion 31 can be connected to the flexible fixing member 322 through the third connection structure and the fourth connection structure.
[0110] Exemplarily, a slot may be provided on the first clamping portion 31 , and a clamping block may be provided on the flexible fixing member 322 . The clamping block is inserted into the slot, thereby connecting the flexible fixing member 322 and the first clamping portion 31 .
[0111] Alternatively, a clamping block may be provided on the first clamping portion 31 , a clamping slot may be provided on the flexible fixing member 322 , and the clamping slot may be sleeved on the clamping block, thereby connecting the flexible fixing member 322 and the first clamping portion 31 .
[0112] The direction of the slot can be extended along the first direction A or the second direction B. The flexible fixing member 322 and the first clamping portion 31 can be connected through the slot and the clamping block.
[0113] It is understandable that when a slot is provided on the first clamping portion 31, the flexible fixing member 322 can also be directly inserted into the slot to connect the flexible fixing member 322 and the first clamping portion 31. The block is inserted into the slot, or the flexible fixing member 322 is inserted into the slot. In order to reduce the probability of the flexible fixing member 322 falling off the first clamping portion 31, the block and the slot, or the flexible fixing member 322 and the slot can be connected by interference fit, or a limiter can be provided on the block or the flexible fixing member 322.
[0114] As another example, threaded holes may be provided on both the flexible fixing member 322 and the first clamping portion 31 , the threaded holes on the flexible fixing member 322 and the first clamping portion 31 are aligned, and screws are screwed into the threaded holes to connect the flexible fixing member 322 and the first clamping portion 31 .
[0115] In the above embodiment, by connecting the flexible fixing member 322 to the first clamping portion 31 in a detachable manner, it is convenient for the user to replace the flexible fixing member 322, or to adjust the position of the flexible fixing member 322 on the first clamping portion 31, so as to clamp objects 5 of different sizes.
[0116] In some embodiments of the present application, a limiting portion is provided at one end of the first clamping portion 31 and / or the second clamping portion 32 away from the base 1, and the limiting portion has a limiting structure adapted to the clamped object 5 so as to clamp the clamped object 5.
[0117] In the embodiment of the present application, a limiting portion may be provided at one end of the first clamping portion 31 away from the base 1; or a limiting portion may be provided at one end of the second clamping portion 32 away from the base 1; or a limiting portion may be provided at one end of both the first clamping portion 31 and the second clamping portion 32 away from the base 1. The limiting portion has a limiting structure matching the clamped object 5, and the limiting portion fits the clamped object 5 through the limiting structure, thereby clamping the clamped object 5.
[0118] Exemplarily, a limiting portion may be provided at one end of the first clamping portion 31 and / or the second clamping portion 32 away from the base 1. The limiting portion may include a limiting section and a bending section. Taking the first clamping portion 31 as an example, one end of the limiting section is connected to the end of the first clamping portion 31 away from the base 1 and extends in the direction toward the clamped object 5; the other end of the bending section is connected to the limiting section and extends in the direction toward the base 1. There may be an angle between the limiting section and the bending section, which may be 10°, 20° or 30°, etc., which can limit the arbitrary shaking of the clamped object 5 and can clamp the clamped object 5 tightly.
[0119] Among them, the limiting section can be fixed to the first clamping portion 31 by fasteners such as bolts, and the bending section can be connected to the limiting section by fasteners such as bolts. Alternatively, the limiting section can be integrally formed with the first clamping portion 31, and the bending section can be integrally formed with the limiting section. Alternatively, the limiting section can be connected to the bending section by a damping shaft or a hinge, etc., so as to adjust the angle between the bending section and the limiting section. In the embodiments of the present application, no specific restrictions are made on the structure, shape, size, etc. of the bending section, and no specific restrictions are made on the structure, shape, size, etc. of the limiting section, and no specific restrictions are made on the angle between the bending section and the limiting section.
[0120] In another example, the limiting portion may include a magnetic member, such as a magnet; a magnetic conductive member, such as an iron sheet, is disposed on the side of the clamped object 5 close to the limiting portion. Alternatively, the limiting portion may include a magnetic conductive member, such as an iron sheet; a magnetic member, such as a magnet, is disposed on the side of the clamped object 5 close to the limiting portion; the magnet and the iron sheet can attract each other under the action of suction, thereby fixing the clamped object 5 on the first clamping portion 31.
[0121] The magnetic part or iron sheet can be connected to the first clamping portion 31 through suitable parts; or, a corresponding structure is provided on the first clamping portion 31, such as a slot, and the magnetic part or iron sheet is connected to the first clamping portion 31 by placing the magnetic part or iron sheet into the slot.
[0122] In another example, the limiting part can be a clamping member, such as a part with a clamping function such as a claw. When the clamped object 5 is placed on the support member 2, the edge of the support member 2 along the second direction B is clamped by the clamping member; or, the corner position of the support member 2 is clamped by the clamping member. Thus, the clamping member is fixed.
[0123] It should be explained that the limiting parts on the first clamping part 31 and the second clamping part 32 can be the same. For example, the first clamping part 31 and the second clamping part 32 both clamp the clamped object 5 by magnetic parts. The limiting parts on the first clamping part 31 and the second clamping part 32 can be different. For another example, the first clamping part 31 can clamp the clamped object 5 by magnetic parts, and the second clamping part 32 can clamp the clamped object 5 by limiting sections and bending sections. The embodiment of the present application does not specifically limit the structure of the limiting part, and it is sufficient that the clamped object 5 can be clamped by the limiting part.
[0124] In the above embodiment, due to the setting of the limiting portion, the setting of the limiting portion can reduce the probability of the clamped object 5 shaking randomly on the bracket, can clamp the clamped object 5, and improve the stability of the bracket when fixing the clamped object 5.
[0125] The following is an explanation of the use process of the bracket that can clamp objects of different postures provided by the present application. When using the bracket that can clamp objects of different postures provided by the present application, first fix the base 1 on the object to be installed, and then place the clamped object 5 on the support 2, the clamped object 5 can fit with the support 2, and the support 2 provides support and protection for the clamped object 5. After the clamped object 5 is placed on the support 2, under the action of the weight of the clamped object 5 itself, the support 2 moves in the first direction A in the direction away from the base 1. The support 2 will drive the reset member 4 to move during the movement, and the support 2 can also drive the connecting member 33 to move; the connecting member 33 slides in the inclined groove 111, and the connecting member 33 can drive the first clamping part 31 connected thereto to move; taking the two first clamping parts 31 as an example, the two first clamping parts 31 can move in the second direction B in the direction of approaching each other, thereby fixing the clamped object 5 on the bracket.
[0126] After the clamping member clamps the clamped object 5, the user can use the clamped object 5 normally. When the clamped object 5 needs to be removed from the bracket, the user can remove the clamped object 5 from the support member 2. When the clamped object 5 is removed from the support member 2, the support member 2 will no longer be subjected to the force, and the reset member 4 can be reset. The support member 2 is reset as the reset member 4 is reset. At the same time, the support member 2 will drive the connecting member 33 to reset during the reset process. The connecting member 33 drives the two first clamping parts 31 to move away from each other along the first direction A, thereby resetting the first clamping part 31. After the first clamping part 31 is reset, the first clamping part 31 no longer fixes the clamped object 5, so that the clamped object 5 can be removed from the bracket.
[0127] The clamping assembly 3 can fix the clamped object 5 in different positions on the bracket in the following ways:
[0128] S100: When the clamped object 5 in the first posture is placed on the support 2, the clamped object 5 is located between the two first clamping parts 31, and the clamped object 5 in the first posture is clamped by the two first clamping parts 31; when the clamped object 5 in the second posture is placed on the support 2, the clamped object 5 is located between the two second clamping parts 32, and the clamped object 5 in the second posture is clamped by the two second clamping parts 32.
[0129] S200: When the clamped object 5 in the first posture is placed on the support 2, the clamped object 5 is located between the two first clamping parts 31, and the clamped object 5 in the first posture is clamped by the two first clamping parts 31; or, when the clamped object 5 in the second posture is placed on the support 2, the flexible fixing part 322 can be bent in the direction close to the base 1, and the clamped object 5 is located between the two flexible fixing parts 322, and the clamped object 5 in the second posture is clamped by the two flexible fixing parts 322.
[0130] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
