Description

Technical Field

[0001] The utility model relates to the technical field of electronic product brackets, in particular to a gravity bracket. Background Art

[0002] At present, gravity stands for supporting products such as mobile phones, when a mobile phone is placed on the bottom bracket, the bottom bracket moves downward based on the gravity of the mobile phone itself. When the bottom bracket moves, the two side clamps of the mobile phone stand can be driven to move toward each other through the transmission structure, thereby clamping the mobile phone and keeping the mobile phone in a vertical screen clamped state. However, when the mobile phone needs to be switched from the vertical screen state to the horizontal screen state, the mobile phone cannot continue to press the bottom bracket, which will cause the clamp arms to open and cannot continue to provide clamping force to the mobile phone, making the mobile phone easy to slip. Therefore, the current gravity stands have the problem of not being able to continue to clamp the mobile phone in the horizontal screen state. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0029] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0030] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0031] like Figures 1 to 3As shown, an embodiment of the utility model provides a gravity bracket, including: a base 1, a shell 2, a clamping assembly 3 and a transmission assembly 4; the base 1 is usually directly or indirectly connected to a specified position in the environment, and can be a fixed connection or a connection with an adjustable position, and can be a detachable connection or a non-detachable connection, and no further restrictions are made here; the shell 2 is used for placing the device to be clamped, and the "device to be clamped" can usually be a mobile terminal device such as a mobile phone or a tablet computer. The shell 2 is connected to the base 1 and can move relative to the base 1, such as rotational movement or linear movement. A first connecting structure 11 is provided on the base 1, and a second connecting structure 21 is provided on the shell 2. The first connecting structure 11 and the second connecting structure 21 cooperate with each other to adjust the relative position between the shell 2 and the base 1 when the shell 2 and the base 1 move relative to each other. The clamping assembly 3 is movably connected to the shell 2, and is used for clamping a device placed on the shell in the first use state; the transmission assembly 4 is connected to the clamping assembly 3, and the transmission assembly 4 is at least used to drive the clamping assembly 3 to further clamp the device when the shell 2 and the base 1 move relative to each other and the clamping assembly 3 is switched from the first use state to the second use state, thereby achieving the function of keeping the device clamped in both the first use state and the second use state without loosening the device.

[0032] In some embodiments, the shell 2 can rotate relative to the base 1, and the use state of the device placed on the shell 2 can be adjusted by rotating the shell 2, such as the landscape state, the portrait state, or other use states between the landscape and portrait states. The clamping assembly 3 is movably connected to the shell 2 and can move relative to the shell 2 to clamp or loosen the device placed on the shell 2; the clamping assembly 3 is used to clamp the device in the first use state. In some designs, the "first use state" specifically refers to the portrait state, that is, the device will be clamped by the clamping assembly 3 when used in the portrait state. For example, due to the effect of gravity, the device presses the components of the clamping assembly 3 downward, causing the clamping assembly 3 to produce corresponding movement, thereby clamping the device in the portrait state, so that the user can use the device in the portrait state.

[0033] In some embodiments, the connection between the transmission assembly 4 and the clamping assembly 3 can transmit motion and power, so that the transmission assembly 4 can drive the clamping assembly 3 to move and further clamp the device when the housing 2 and the base 1 move relative to each other and the clamping assembly 3 switches from the first use state to the second use state. In order to realize the function of the transmission assembly 4, the transmission assembly 4 should be able to identify the rotation of the housing 2 relative to the base 1 and respond to it. For example, the transmission assembly 4 can be connected to the housing 2 and / or the base 1 so that the movement and power of the housing 2 are transmitted to the transmission assembly 4, and then the transmission assembly 4 drives the clamping assembly 3 to move to clamp the device. Among them, the relative movement between the housing 2 and the base 1 can be a linear motion, and the corresponding first connection structure and the second connection structure can be a linear slide rail and a linear slide groove that can guide the linear motion. The relative movement between the housing 2 and the base 1 can also be a rotational motion, in which case the corresponding first connection structure and the second connection structure can be an arcuate slide rail and an arcuate slide groove that can guide the rotational motion. In this way, when the relative position between the shell 2 and the base 1 changes, they can be automatically locked synchronously during the change process without retreating, and the transmission component 4 can recognize the position change between the shell 2 and the base 1, and obtain driving force to generate movement, and then drive the clamping component 3 connected to the transmission component 4 to move so as to further clamp the device.

[0034] In the gravity bracket provided by the utility model, the transmission component 4 drives the clamping component 3 to move when the shell 2 switches the use state, so that the clamping component 3 keeps clamping the device in the process of switching the use state. At this time, the gravity bracket can be applied to a variety of scenarios for using the device, and the device can be switched to a horizontal screen, a vertical screen, or a use state between the horizontal screen and the vertical screen at will. The applicable scenarios are more extensive and the use experience is improved. At the same time, when switching from the first use state to the second use state, not only can the device be further clamped, but the further clamping operation can be achieved by only one movement mode, without the need for step-by-step operation of different steps, and the convenience of use is good.

[0035] Specifically, in the embodiment of the utility model, the first connecting structure 11 on the base 1 cooperates with the second connecting structure 21 on the shell 2, so that an adjustable relative position connection is formed between the base 1 and the shell 2, thereby meeting the demand for rotating the shell 2 to adjust the use state. Combined with the recognition response of the transmission component 4 to the relative movement between the shell 2 and the base 1, it is achieved that the clamping component 3 can clamp the device under different use states.

[0036] The gravity support provided by the embodiment of the utility model comprises a base 1, a shell 2, a clamping assembly 3 and a transmission assembly 4. The shell 2 is connected to the base 1 and can move relative to the base 1. The clamping assembly 3 is connected to the shell 2 and can clamp and fix the device placed on the shell 2. By adopting a first connection structure 11 provided on the base 1 and a second connection structure 21 provided on the shell 2, the first connection structure 11 and the second connection structure 21 cooperate with each other, so that the relative position between the shell 2 and the base 1 can be adjusted. At the same time, by adopting the transmission assembly 4 to connect with the clamping assembly 3, the driving force on the transmission assembly 4 can be transmitted to the clamping assembly 3. In this way, when the shell 2 on which the device is placed rotates relative to the base 1 to switch the use state, the transmission assembly 4 can obtain the driving force generated when the relative position between the shell 2 and the base 1 changes, and then can drive the clamping assembly 3 to maintain the clamping of the device and can further increase the clamping force, so that the clamping is more effective, thereby solving the problem that the gravity support cannot continue to clamp the device in the horizontal screen state. Moreover, further clamping can be achieved by pushing the shell 2 to move linearly relative to the base 1 or rotating the shell 2 relative to the base 1, etc., without the need to complete it step by step through different operation steps. It can be completed in one step, thereby improving the convenience of operating the gravity bracket.

[0037] In some embodiments, the first connection structure 11 and the second connection structure 21 cooperate with each other to make the shell 2 and the base 1 rotate relative to each other, so as to adjust the relative position between the shell 2 and the base 1 when the shell 2 and the base 1 rotate relative to each other, and the transmission component 4 is at least used to drive the clamping component 3 to further clamp the device when the shell 2 and the base 1 rotate relative to each other and the clamping component 3 switches from the first use state to the second use state. That is, in this embodiment, the shell 2 and the base 1 are relatively rotated under the cooperation of the first connection structure 11 and the second connection structure 21, and the transmission component 4 can obtain the driving force by rotating the shell 2, and then can further clamp the device with the clamping component 3. This kind of further clamping of the device is achieved by rotation. The operation of further clamping by rotation is the same as the operation of rotating to switch the use state of the device, so that the further clamping operation can be completed synchronously during the process of rotating to switch the use state of the device, further improving the convenience of using the gravity bracket.

[0038] In some embodiments, such as Figure 3As shown, the first connection structure 11 is an external thread, and the second connection structure 21 is an internal thread; or the first connection structure 11 is an internal thread, and the second connection structure 21 is an external thread. In this embodiment, the first connection structure 11 and the second connection structure 21 are set as mutually matching thread structures, so that the base 1 and the shell 2 can rotate relative to each other around the axis where the thread is located, so that the use states such as horizontal screen and vertical screen can be switched, and the rotation is stable and reliable. In addition, the mutually matching thread structures can also synchronously lock the rotation position of the shell 2 relative to the base 1, and it will not retreat, and the clamping is reliable, so it can be automatically locked without setting a locking mechanism, and the design is ingenious.

[0039] In some embodiments, such as Figure 2 and Figure 3 As shown, the transmission assembly 4 includes a transmission gear 41, a first clutch 42 and a second clutch 43. The transmission gear 41 is movably connected in the housing 2 and connected to the clamping assembly 3. The transmission gear 41 is used to drive the clamping assembly 3 to clamp or loosen; the first clutch 42 is connected to the transmission gear 41; the second clutch 43 is connected to the base 1, and the second clutch 43 is used to contact and drive with the first clutch 42 when the housing 2 and the base 1 move relative to each other and the clamping assembly 3 is switched from the first use state to the second use state, so that the transmission gear 41 drives the clamping assembly 3 to further clamp the device. Specifically, the transmission gear 41 is movably connected to the housing 2 rather than fixedly connected to ensure that the housing 2 and the transmission gear 41 can rotate separately without causing mutual interference. The transmission gear 41 is connected to the clamping assembly 3 to drive the clamping assembly 3 to move. Specifically, the clamping assembly 3 may include a transmission component such as a rack and a worm that mesh with the transmission gear 41 to convert the rotation of the transmission gear 41 into a linear motion of clamping or loosening the clamping assembly 3.

[0040] Specifically, the first clutch 42 and the second clutch 43 are components that can be in contact with each other for transmission or separated from each other, and the positional relationship between the two determines whether power can be transmitted to the transmission gear 41. In the embodiment of the utility model, the first clutch 42 is connected to the transmission gear 41, and the second clutch 43 is connected to the base 1. In this way, in the first use state, the first clutch 42 and the second clutch 43 are in a non-contact state, and when the rotating shell 2 rotates relative to the base 1 to switch the use state, the distance between the base 1 and the shell 2 is gradually approached by the threaded structure provided between the base 1 and the shell 2, so that the first clutch 42 and the second clutch 43 can contact each other. Since the position of the base 1 is usually fixed, when the shell 2 is rotated, the first clutch 42, the second clutch 43 and the transmission gear 41 remain stationary relative to the shell 2, so that in the process of rotating the shell 2, it is equivalent to the transmission gear 41 rotating in the direction opposite to the rotation direction of the shell 2, thereby achieving further clamping of the clamping assembly 3.

[0041] In some embodiments, the contact transmission between the first clutch 42 and the second clutch 43 may be direct friction transmission, for example, a structure capable of increasing friction may be provided on the contact surfaces of the first clutch 42 and the second clutch 43, such as a bump-bump matching structure, or a bump-pit matching structure. Alternatively, at least the contact surface between the first clutch 42 and the second clutch 43 may be made of a material with a large friction coefficient, such as rubber or silicone, so as to achieve reliable transmission between the first clutch 42 and the second clutch 43.

[0042] In some embodiments, such as Figure 2 As shown, the clamping assembly 3 includes a clamp 31 and a base 32. At least two clamps 31 are provided, and at least two clamps 31 are arranged opposite to each other, and each clamp 31 is movably connected to the shell 2; the base 32 is movably connected to the shell 2, and forms a clamping space for the clamping device with each clamp 31; wherein each clamp 31 and the base 32 are meshed with the transmission gear 41 to synchronously clamp or release the device. Specifically, clamps 31 are respectively provided at opposite sides of the shell 2, so that the clamps 31 on both sides are close to each other when clamping and move away from each other when releasing, and the clamping effect is stable and reliable. Usually, at least two clamps 31 are provided, usually an even number, such as four, six, etc., so that multiple clamps can be symmetrically distributed on both sides of the shell 2, thereby ensuring uniform and stable clamping force. The bottom bracket 32 ​​is used to support the equipment. When the housing 2 is in the vertical screen use state, the bottom bracket 32 ​​is located at the bottom of the housing 2, so that the equipment placed on the housing 2 in the vertical screen presses the bottom bracket 32 ​​under the action of gravity to make it move downward. At the same time, the movement of the bottom bracket 32 ​​is transmitted to each clamp 31 through the transmission gear 41, so that each clamp 31 is relatively close to clamp the equipment. To achieve the above process, each clamp 31 and the bottom bracket 32 ​​are meshed with the transmission gear 41, so that each clamp 31 can synchronously clamp or release the equipment with the movement of the bottom bracket 32. Specifically, a transmission structure such as a rack or a worm gear can be arranged on the clamp 31 and the bottom bracket 32 ​​to mesh with the transmission gear 41, so that the rotation of the transmission gear 41 is converted into the linear movement of the clamp 31 and the bottom bracket 32.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, a first tooth 421 is provided at one end of the first clutch 42 facing the second clutch 43, and a second tooth 431 is provided at one end of the second clutch 43 facing the first clutch 42. The first tooth 421 is meshed with the second tooth 431 to connect the first clutch 42 with the second clutch 43. In this way, the first clutch 42 and the second clutch 43 are connected through the meshing of the teeth, which can achieve a more accurate and stable transmission ratio, and effectively avoid the occurrence of relative sliding or idling, which affects the transmission effect.

[0044] In some embodiments, such as Figure 2 and Figure 3 As shown, a first positioning portion is provided on the first clutch member 42, and a second positioning portion is provided on the transmission gear 41. The first positioning portion and the second positioning portion are matched and connected to realize reliable transmission between the transmission gear 41 and the first clutch member 42. Specifically, the first positioning portion can be a first positioning block 422, and the second positioning portion can be a first positioning groove 411. The first positioning block 422 is arranged in the first positioning groove 411 to realize stable transmission without slipping, and the transmission position error can be reduced. Of course, it can be understood that the first positioning portion can also be a first positioning groove, and the second positioning portion can be a first positioning block, which can also meet the use requirements. The position where the first positioning portion is arranged on the first clutch member 42 and the position where the second positioning portion is arranged on the transmission gear 41 can realize connection without interfering with the movement of other components, and there is no limitation here.

[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, the first clutch 42 can also be fixedly connected to the transmission gear 41 by a fastener 44. Optionally, the fastener 44 can be selected from screws, rivets, locks and other components, and the number of fasteners 44 can be one or more, as long as the first clutch 42 and the transmission gear 41 are fixedly connected. For ease of disassembly, the fastener 44 can be selected from screws. It is understandable that the first clutch 42 and the transmission gear 41 can be fixedly connected without the fastener 44. For example, the first clutch 42 and the transmission gear 41 can be fixedly connected by gluing, welding, integral molding and the like. It is also possible that while the fastener 44 is used to achieve the fixed connection, gluing is also used to further improve the stability of the connection.

[0046] In some embodiments, such as Figure 2 and Figure 3 As shown, the second clutch 43 is provided with a first anti-rotation portion, and the base 1 is provided with a second anti-rotation portion. The first anti-rotation portion and the second anti-rotation portion are connected in cooperation to achieve reliable transmission between the base 1 and the second clutch 43. Specifically, the first anti-rotation portion can be the second positioning groove 432, and the second anti-rotation portion can be the second positioning block 12. The second positioning block 12 is arranged in the second positioning groove 432 to achieve stable transmission. At the same time, it can also play a role in guiding connection, so that the base 1 and the second clutch 43 can be accurately connected. Of course, it can be understood that the first anti-rotation portion can also be the second positioning block, and the second anti-rotation portion can be the second positioning groove, which can also meet the use requirements. The position where the first anti-rotation portion is arranged on the second clutch 43 and the position where the second anti-rotation portion is arranged on the base 1 can achieve connection without interfering with the movement of other components, and there is no limitation here.

[0047] In some embodiments, such as Figure 2 As shown, the base 1 is provided with a receiving cavity 13, and the second clutch 43 is provided in the receiving cavity 13. In this way, by providing the second clutch 43 in the receiving cavity 13, the internal space of the base 1 is fully utilized, the connection structure is made more compact, the space occupied by the second clutch 43 is saved, and the thickness between the second clutch 43 and the base 1 is reduced, which is conducive to the compactness of the entire gravity bracket.

[0048] In some embodiments, such as Figure 3 As shown, a limit block 14 is provided on the base 1, and a limit groove 22 for accommodating the limit block 14 and a stop block 23 for abutting and limiting with the limit block 14 are provided on the shell 2, wherein the limit block 14 abuts with the stop block 23 to limit the range of relative rotation between the shell 2 and the base 1; or a limit block is provided on the shell 2, and a limit groove for accommodating the limit block and a stop block for abutting and limiting with the limit block are provided on the base 1, and the limit block abuts with the stop block to limit the range of relative rotation between the shell 2 and the base 1. Specifically, during the relative rotation between the base 1 and the shell 2, the limit block 14 moves in the limit groove 22, and therefore, the size of the limit groove 22 should generally be larger than the limit block 14, so that the limit groove 22 can accommodate the limit block 14 and leave a certain amount of movable space. When the base 1 and the shell 2 rotate relative to each other to the extreme position, the limit block 14 moves to the edge of the limit groove 22 and abuts against the stop block 23, thereby preventing further rotation between the base 1 and the shell 2 and achieving a limiting effect. This design can avoid problems such as loosening between the base 1 and the shell 2 due to excessive rotation, and ensure that the shell 2 rotates within a reasonable range.

[0049] It can be understood that the setting positions of the limit block 14, the limit groove 22 and the stop block 23 are interchangeable. The limit block 14 can be set on the base 1, and the limit groove 22 and the stop block 23 can be set on the shell 2, or the limit groove and the stop block can be set on the base 1, and the limit block can be set on the shell 2, and the same limiting effect can be achieved.

[0050] In some embodiments, such as Figure 3As shown, a first locking structure 141 is provided on the limit block 14, and a second locking structure 221 is provided in the limit groove 22; wherein, the first locking structure 141 and the second locking structure 221 cooperate to lock the position between the shell 2 and the base 1. Specifically, the cooperation position of the first locking structure 141 and the second locking structure 221 corresponds to the specified position of the shell 2, so that the shell 2 is locked in a specified use state, such as a horizontal screen or a vertical screen state, to ensure that a certain use state is not easily damaged by external disturbances. The first locking structure 141 and / or the second locking structure 221 can be provided in plurality, and any first locking structure 141 can cooperate with any second locking structure 221, so that the shell 2 can be locked in a variety of use states. The first locking structure 141 and the second locking structure 221 can specifically be a detachable connection structure such as a snap-on structure.

[0051] The design of the above embodiment can lock the position of the housing 2 so as to keep it in certain specific use states to ensure the stability of the bracket in use.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the gravity bracket further includes a connection base 5 for supporting the base 1, one end of the connection base 5 is connected to the mounting position, and the other end is connected to the base 1. Specifically, the mounting position specifically refers to a designated position in the use environment of the gravity bracket, and the connection between the connection base 5 and the mounting position and the base 1 can be a fixed connection or an adjustable position connection, a detachable connection or a non-detachable connection, and the utility model does not make further restrictions on this, but for ease of use, a fixed and detachable connection method can be adopted between the connection base 5 and the mounting position, and an adjustable position and detachable connection method can be adopted between the connection base 5 and the base 1.

[0053] In some embodiments, the gravity support further includes a locking cap 6 , which is disposed on the base 1 and / or the connecting seat 5 , and is used to lock the connecting position between the base 1 and the connecting seat 5 .
