Description

Technical Field

[0001] This utility model relates to the technical field of electrical product accessories, specifically a smartphone holder with a three-dimensional shock absorption function.

Background Art

[0002] With the popularization of smartphones, in-vehicle holders and bicycle holders have become common accessories for users to fix their smartphones during movement. This type of holder usually fixes the smartphone by a clamping mechanism and is attached to a handlebar, a rearview mirror mounting seat, etc. via a ball joint or a clamp. In actual use, multi-directional vibrations occur when the vehicle is running. These include vertical impacts due to uneven road surfaces, lateral centrifugal forces generated during turning, and high-frequency resonances associated with the operation of the engine, and these vibrations are directly transmitted to the smartphone.

[0003] Many existing smartphone holders adopt a rigid connection or a simple single-point shock absorption structure, and cannot effectively block composite vibrations from different directions, making it difficult to achieve both multi-directional vibration shock absorption and structural compactness. Therefore, there is a problem that the optical shake correction mechanism of the smartphone camera is easily damaged by long-term vibrations.

[0004] Therefore, in order to solve the above problems, this utility model proposes a smartphone holder with a three-dimensional shock absorption function.

Summary of the Invention

[0005] In view of the deficiencies of the prior art, this utility model provides a smartphone holder with a three-dimensional shock absorption function, aiming to solve the problems pointed out in the above-mentioned background art, that is, many existing holders adopt a rigid connection or a single-point shock absorption structure, making it difficult to achieve both effective vibration shock absorption in multiple directions and structural compactness, and the shake correction mechanism of the camera is easily damaged.

[0006] To achieve the above objective, this utility model adopts the following technical approach. A smartphone holder equipped with a three-dimensional shock absorption function includes a shock absorption mechanism, which has a first connection part for connecting a smartphone clamp component and a second connection part for connecting an external mounting component. The shock absorption mechanism comprises at least one pair of first elastic shock absorbers and at least one pair of second elastic shock absorbers, wherein the first and second elastic shock absorbers are configured to provide elastic support between the first and second connecting portions in at least two different directions, thereby connecting the first and second connecting portions in a floating state and forming a three-dimensional buffer space between them.

[0007] Furthermore, the shock absorption mechanism further includes the following configuration. The shock-absorbing frame has a rectangular frame shape, and a first mounting hole is formed at each of its four corners. There are four of the aforementioned first elastic shock absorbers, and each of the first elastic shock absorbers is inserted into its corresponding first mounting hole. Here, the outer shape of the first elastic shock absorber is configured as a drum shape with both ends contracted and the center part bulging, and a central hole is provided inside that penetrates in the axial direction. In addition, one end of the first elastic shock absorber abuts against the first connecting part, and an annular slot is recessed in the outer circumferential surface of the other end, and the first elastic shock absorber is fitted into the edge of the first mounting hole via the annular slot.

[0008] Furthermore, the shock absorption mechanism further comprises a plurality of first fixing members, which are arranged in a one-to-one correspondence with the first elastic shock absorber. The shaft portion of the first fixing member is inserted into the central hole from the end on which the first elastic shock absorber is fitted into the first mounting hole, and is locked into the first connecting portion. Its head is embedded inside the end of the first elastic shock absorber and does not come into contact with the shock absorption frame.

[0009] Furthermore, the second connection portion includes an impact-absorbing connection spot, which is suspended and positioned within the internal space of the impact-absorbing frame. Four of the second elastic impact absorbers are arranged, each positioned between the impact-absorbing frame and the impact-absorbing connection spot. Second mounting holes are provided in the top wall, bottom wall, and both side walls of the shock-absorbing frame, and a number of corresponding connection slots are provided on the outer surface of the shock-absorbing connection spot, with a first nut insert pre-embedded inside the connection slot. The second elastic shock absorber is shaped like a stepped sleeve, with both ends abutting against the second mounting hole and the connection slot, respectively. The shock absorption mechanism further comprises a plurality of second fixing members, the shafts of which are inserted through the second mounting hole and the second elastic shock absorber and locked into the first nut insert, and the heads of which are movably housed within the second mounting hole. As a result, the shock absorbing connection spot is floatingly supported within the shock absorbing frame.

[0010] Furthermore, the smartphone clamp component has the following configuration. The housing consists of a front cover, an intermediate frame, and a rear cover that are stacked and fixed together. The first connecting portion is a connecting pin molded on the back surface of the rear cover. One end of the first elastic shock absorber is fitted onto the outer circumference of the connecting pin, and the first fixing member is inserted from the other end of the first elastic shock absorber and locked into the connecting pin. The device comprises a leg support and two clamping arms, the leg support being slidably mounted below the housing, and the two clamping arms being slidably mounted on the left and right sides of the housing, respectively. Flexible pad members are embedded in the mounting surface of the leg support and in the opposing surfaces of the two clamping arms, respectively. At least one first guide rod is connected to the leg support portion, and at least one second guide rod is connected to the clamp arm. The first and second guide rods are each inserted into the housing and positioned axially by spring washers.

[0011] Furthermore, the smartphone clamp component is further equipped with a bottom locking mechanism, and this bottom locking mechanism includes the following configuration. The pressing block is slidably mounted within the slide slot of the rear cover, and the pressing block has a pressing slot formed therein that conforms to the outer shape of the first guide rod. The first cam rod is fixedly mounted within the slide slot, with one end extending through the pressing block to the outside of the rear cover. The first cam lever is rotatably connected to the outer end of the first cam rod. By operating the first cam lever, the pressing block is driven via the first cam rod, and by pressing the first guide rod, the protruding length of the leg support can be fixed.

[0012] Furthermore, the smartphone clamp component is further equipped with a lateral locking mechanism, which comprises an adjustment screw, an axially fixed nut member, a sleeve, a rotation adjustment component, and a second cam lever. The nut member is mounted within the intermediate frame in a circumferentially fixed state. The threaded portion of the adjustment screw is screwed into the nut member, and its shaft portion (the smooth portion without threads) passes through the clamp arm on one side and is fixed to the rotation adjustment component. The sleeve is movably fitted onto the threaded portion of the adjustment screw and is circumferentially positioned and engaged with the second cam rod. The second cam rod slides through the other clamp arm, and the second cam lever is rotatably connected to the outer end of the second cam rod. When the rotation adjustment component is turned in the loosening direction, the adjustment screw becomes axially movable relative to the nut member, thereby releasing the pressure applied by the rotation adjustment component to the clamp arm. At the same time, the end of the adjustment screw pushes the sleeve axially, releasing the pressure on the other clamp arm as well, providing both clamp arms with space to move outward for adjustment. By rotating the rotation adjustment component in the tightening direction, the two clamp arms can be moved toward each other, and the second cam lever is used to auxiliaryly lock the corresponding clamp arm.

[0013] Furthermore, a first ring gear is provided on the end face of the rotation adjustment component facing the clamp arm, and a second ring gear is provided on the portion of the clamp arm facing the end face. When the rotation adjustment component is tightened, the first ring gear and the second ring gear engage, thereby preventing the rotation adjustment component from rotating in the reverse direction.

[0014] Furthermore, the external mounting component includes a ball connector. A ring-shaped guard extends from the side of the shock-absorbing connection spot opposite to the first connection portion, and a second nut insert is fixed inside the ring-shaped guard. The ball connecting component has a ball portion and a rod connecting portion, and the rod connecting portion is inserted into the internal hole of the ring-shaped guard and fastened to the second nut insert via a fixing screw, thereby achieving an integrated connection between the ball connecting component and the shock absorption mechanism.

[0015] Furthermore, a metal bushing is jointly embedded inside the ball portion and the rod connection portion, and the fixing screw passes through the metal bushing. A ball portion anti-slip covering member is fitted to the outside of the ball portion. The front cover is fixed to the intermediate frame via a fastening member, and the side of the front cover opposite to the intermediate frame is covered with an anti-slip pad to conceal the fastening member. [Effects of the Invention]

[0016] Compared to conventional technology, this utility model provides a smartphone holder equipped with a three-dimensional shock absorption function, and has the following beneficial effects. This utility model forms a floating elastic connection in three directions of front-back, up-down, and left-right between a first elastic shock absorber symmetrically arranged at the four corners and a second elastic shock absorber evenly arranged in the circumferential direction, thereby constructing a multi-dimensional and multi-point three-dimensional buffer space by the cooperation of the two. The first elastic shock absorber is specialized in absorbing longitudinal shocks in a direction perpendicular to the smartphone screen and high-frequency resonances of the engine, and the second elastic shock absorber absorbs vibrations within the screen plane and centrifugal forces in the lateral direction. By the cooperation of both, omnidirectional vibrations are filtered, effectively protecting the optical shake correction mechanism of the smartphone camera. The entire shock absorption mechanism is built into the force transmission path of the holder through the first connection part and the second connection part, eliminating the need to provide an additional module externally, and having a compact and integrated structure.

[Modes for carrying out the invention]

[0019] The technical invention described below will be clearly and completely explained with reference to the attached drawings of the embodiments of this utility model. Clearly, the embodiments described are only a subset of the embodiments of this utility model, not all of them. All other embodiments that can be obtained by a person skilled in the art without creative work based on the embodiments of this utility model are within the scope of protection of this utility model.

[0020] As shown in Figure 1-8, a smartphone holder with a three-dimensional shock absorption function according to one embodiment of the present utility model includes a shock absorption mechanism 1, which has a first connection part for connecting a smartphone clamp part 2 and a second connection part for connecting an external mounting part 3.

[0021] The shock absorption mechanism 1 includes at least one pair of first elastic shock absorbers 11 and at least one pair of second elastic shock absorbers 12, and the first elastic shock absorbers 11 and the second elastic shock absorbers 12 are configured to provide elastic support between the first and second connecting portions in at least two different directions, thereby connecting the first and second connecting portions

[0022] The second connection point is connected to the other in a floating state, and a three-dimensional buffer space is formed between them.

[0023] The shock absorption mechanism 1 is not an external accessory, but is built into the force transmission path of the entire holder by being connected to the smartphone clamp component 2 via its first connection part and to an external mounting component 3 (e.g., a connecting ball) via its second connection part. Inside the shock absorption mechanism 1 are at least one pair of first elastic shock absorbers 11 and at least one pair of second elastic shock absorbers 12, and these two pairs of elastic shock absorbers are arranged in different directions.

[0024] The explanation will be based on the state in which the smartphone clamp component 2 clamps the smartphone. The first elastic shock absorber 11 (silicone material) is positioned along the direction perpendicular to the smartphone screen (defined as the front-to-back direction) and mainly provides elastic support in that direction, absorbing longitudinal shocks from the direction of vehicle travel (e.g., inertial forces due to sudden braking or acceleration, and high-frequency resonance of the engine). The second elastic shock absorber 12 (silicone material) is positioned along the direction parallel to the smartphone screen and functions in the up-down and left-to-right directions, respectively, absorbing vertical vibrations due to uneven road surfaces and lateral centrifugal forces generated when the vehicle turns.

[0025] In actual use, users typically adjust the pitch angle (vertical angle) of the entire smartphone holder via the ball joint of the external mounting part 3, raising the smartphone to a certain angle towards their face. At this time, the entire holder tilts accordingly, so the front-to-back direction no longer points directly in front of the vehicle. However, the definitions of the directions of the first elastic shock absorber 11 and the second elastic shock absorber 12 described above are based on the structural coordinate system of the holder itself. That is, the first elastic shock absorber 11 is always perpendicular to the smartphone screen (regardless of the screen's pitch angle) and primarily absorbs the impact component perpendicular to the screen along that direction. The second elastic shock absorber 12 is always parallel to the smartphone screen and absorbs the impact components in the vertical and horizontal directions within the screen plane. If the direction of the impact force generated by the vehicle's vibration source coincides componentically with the direction of action of either of the elastic bodies described above, the elastic body can effectively perform its shock absorption function. These two sets of elastic bodies cooperate in their respective directions, resulting in a floating elastic connection between the first and second connection points without rigid contact, creating a three-dimensional buffer space between them capable of absorbing shocks from multiple directions. Furthermore, this three-dimensional buffer space automatically adjusts the distribution of shock-absorbing components in each direction according to changes in the holder's tilt angle, always providing an effective shock filtering effect for the smartphone.

[0026] While conventional holders could only absorb shocks at a single point or in a single direction, this embodiment uses the arrangement of multiple sets of multi-directional elastic bodies to form a three-dimensional floating shock absorption system in the front-to-back, up-and-down, and left-to-right directions based on the holder's own coordinate system. The first elastic shock absorber 11 is specialized for absorbing shocks perpendicular to the smartphone screen and high-frequency resonances of the engine, while the second elastic shock absorber 12 is specialized for absorbing vibrations within the screen plane and lateral vibrations. By working together, the two achieve vibration filtering in all directions. Even when the smartphone is used upright and the entire holder is tilted, the direction of action of each elastic body is still perpendicular or parallel to the screen, allowing for effective absorption of the vertical and parallel components of vibrations, respectively. This effectively protects the smartphone camera's optical image stabilization mechanism from multi-dimensional vibration interference. At the same time, the shock absorption mechanism 1 is built into the holder via the first and second connection parts, eliminating the need for additional external modules, thus achieving miniaturization and integration of the structure.

[0027] As shown in Figure 1-8, in some embodiments, the shock absorption mechanism 1 further comprises the following configurations.

[0028] The shock-absorbing frame 13 has a rectangular frame shape, and first mounting holes 131 are formed at each of its four corners.

[0029] There are four of the first elastic shock absorbers 11, and each of the first elastic shock absorbers 11 is inserted into the corresponding first mounting hole 131.

[0030] Here, the outer shape of the first elastic shock absorber 11 is configured as a drum shape with both ends contracted and the center part bulging, and a central hole is provided inside that penetrates in the axial direction. In addition, one end of the first elastic shock absorber 11 abuts against the first connecting part, and an annular slot 111 is recessed on the outer circumferential surface of the other end, and the first elastic shock absorber 11 is fitted into the edge of the first mounting hole 131 via the annular slot 111.

[0031] The shock absorption mechanism 1 further includes a shock absorption frame 13 that serves to support and position the structure. The shock absorption frame 13 is a rigid rectangular frame, and each of its four corners has a first mounting hole 131. Specifically, four first elastic shock absorbers 11 are arranged, corresponding one-to-one with the four first mounting holes 131, forming a symmetrical layout. The outer shape of each first elastic shock absorber 11 is designed to be a drum shape, with both ends contracting and the center expanding. This drum-shaped structure allows the center to undergo elastic deformation first when subjected to compressive force from the front-to-back direction, effectively absorbing vibration energy. At the same time, the outwardly expanding waist expands radially during deformation, providing a certain radial support force and limiting lateral displacement. A central hole is provided inside the first elastic shock absorber 11, penetrating axially, and is used to insert a fixing member. During installation, one end of the first elastic shock absorber 11 directly contacts the surface of the first connection part, and a circular annular slot 111 is recessed on the outer circumferential surface of the other end. The first elastic shock absorber 11 is precisely fitted and fixed into the edge of the first mounting hole 131 via the annular slot 111. This enables a removable collar fitting and fixing between the shock absorbing frame 13 and the first elastic shock absorber 11, eliminating the need for additional fixing members or adhesives.

[0032] Four drum-shaped first elastic shock absorbers 11, symmetrically positioned at the four corners, form a stable four-point floating support between the shock-absorbing frame 13 and the first connection point. When subjected to longitudinal impact from the front-rear direction, the four elastic bodies simultaneously compress and deform to absorb energy, resulting in high shock absorption efficiency. When subjected to disturbances from the vertical or horizontal direction, the bulge at the waist of the drum-shaped structure provides additional radial support force, suppressing excessive lateral displacement at the first connection point and ensuring the stability of the support. The connection method, using the fitting of the annular slot 111 and the first mounting hole 131, provides a simple, reliable, and easy-to-assemble connection means. The elastic bodies are less likely to fall off even when subjected to repeated deformation, and maintenance and replacement are also easy.

[0033] As shown in Figure 1-8, in some embodiments, the shock absorption mechanism 1 further comprises a plurality of first fixing members 14, which are arranged in a one-to-one correspondence with the first elastic shock absorber 11. The shaft portion of the first fixing member 14 is inserted into the central hole from the end on which the first elastic shock absorber 11 is fitted into the first mounting hole 131, and is locked into the first connecting portion. Its head is embedded inside the end of the first elastic shock absorber 11 and does not come into contact with the shock absorption frame 13.

[0034] The central hole of the first elastic shock absorber 11 has a reduced inner diameter at a position corresponding to the annular slot 111, which tightly covers the shaft portion (smooth portion without threads) near the head of the first fixing member 14, thereby improving assembly stability and centering accuracy.

[0035] The body of the first fixing member 14 is a screw, having a shaft and a head located at one end of the shaft, with the diameter of the head being larger than the diameter of the shaft. Each first fixing member 14 is arranged in a one-to-one correspondence with one first elastic shock absorber 11. During assembly, the shaft of the first fixing member 14 is inserted from the end on which the first elastic shock absorber 11 is fitted into the first mounting hole 131, passes through the entire central hole, and then the threaded portion at its tip is screwed into and fastened to the first connecting part. This firmly connects the first connecting part and the first elastic shock absorber 11.

[0036] The key point is that the head of the first fixing member 14 is not exposed or directly pressing against the shock-absorbing frame 13 as in conventional designs, but is completely embedded in the elastic material inside the end of the first elastic shock absorber 11. The elastic material completely encloses the head, and there is a gap between the head and the shock-absorbing frame 13, so they do not come into direct contact with each other. When a relative displacement occurs between the shock-absorbing frame 13 and the first connection part, and the first elastic shock absorber 11 is compressed, the first fixing member 14 moves synchronously with the first connection part, and its head moves inside the elastic material without colliding with the shock-absorbing frame 13 at all.

[0037] Because the screw head of the first fixing member 14 is completely encased in elastic material, the possibility of contact between the metal head and the shock-absorbing frame 13 during vibration is fundamentally eliminated, completely eliminating abnormal noises and sounds caused by metal-to-metal collisions, and improving the user experience of the product. At the same time, this assembly method ensures the reliability of the fastening. Since the shaft of the first fixing member 14 penetrates the entire first elastic shock absorber 11 and is fastened to the first connection part, a strong axial connection is formed between the first elastic shock absorber 11 and the first connection part, preventing loosening or detachment even under prolonged vibration.

[0038] As shown in Figure 1-8, in some embodiments, the second connection portion includes an impact-absorbing connection spot 15, which is suspended and arranged within the internal space of the impact-absorbing frame 13. Four of the second elastic impact absorbers 12 are arranged, each positioned between the impact-absorbing frame 13 and the impact-absorbing connection spot 15.

[0039] Second mounting holes 132 are provided in the top wall, bottom wall, and both side walls of the shock-absorbing frame 13, and a plurality of corresponding connection slots 151 are provided on the outer surface of the shock-absorbing connection spot 15, with a first nut insert 152 pre-embedded inside each connection slot 151.

[0040] The second elastic shock absorber 12 is shaped like a stepped sleeve, with both ends abutting against the second mounting hole 132 and the connection slot 151, respectively. The shock absorption mechanism 1 further comprises a plurality of second fixing members 16, the shafts of which are inserted through the second mounting hole 132 and the second elastic shock absorber 12 and locked into the first nut insert 152, and the heads of which are movably housed within the second mounting hole 132. As a result, the shock absorbing connection spot 15 is floatingly supported within the shock absorbing frame 13.

[0041] The second connection point is specifically an impact-absorbing connection spot 15, which is suspended in the central internal space of the impact-absorbing frame 13, with a gap provided between each of its four sides and the inner wall of the impact-absorbing frame 13. The four second elastic impact absorbers 12 are positioned between the top wall, bottom wall, and both side walls of the impact-absorbing frame 13 and the outer surface of the impact-absorbing connection spot 15, respectively, forming four-way circumferential support.

[0042] Specifically, second mounting holes 132 are provided in the top wall, bottom wall, and both side walls of the shock-absorbing frame 13, and connection slots 151 are machined into the outer wall of the corresponding shock-absorbing connection spot 15. A first nut insert 152 is pre-embedded inside the connection slot 151, providing a metal base for screw connection. The second elastic shock absorber 12 is in the shape of a stepped sleeve, with one end having a larger diameter and the other end having a smaller diameter. The end with the larger diameter is fitted and positioned within the connection slot 151 of the shock-absorbing connection spot 15, and the end with the smaller diameter is fitted and positioned within the second mounting hole 132 of the shock-absorbing frame 13, forming a flexible support bridge from the shock-absorbing frame 13 to the shock-absorbing connection spot 15. The body of the second fixing member 16 is a screw, and its shaft is inserted into the second mounting hole 132 from the outside of the shock-absorbing frame 13, passes through the internal boreway of the second elastic shock absorber 12, and then the threaded tip is screwed into the first nut insert 152 which is pre-embedded in the connection slot 151. This fixes the second elastic shock absorber 12 and the shock-absorbing connection spot 15 together. On the other hand, the head of the second fixing member 16 is movably housed in the second mounting hole 132 and is not fixed, and there is a gap between the head and the inner wall of the second mounting hole 132, allowing it to move freely along the axial direction of the second mounting hole 132.

[0043] When the holder is subjected to vertical vibration, the impact force is transmitted to the second elastic shock absorbers 12 at the top and bottom via the shock-absorbing frame 13. The elastic body elastically deforms to absorb energy, and at the same time, the head of the second fixing member 16 moves freely up and down within the second mounting hole 132. When subjected to lateral centrifugal force in the left-right direction, the second elastic shock absorbers 12 on both sides function similarly. The second elastic shock absorbers 12 employ a stepped sleeve design with one end larger and the other smaller. The larger diameter end is fitted into the connection slot 151 to provide a larger support area and stability, while the smaller diameter end is fitted into the second mounting hole 132 to facilitate fitting and positioning with the mounting hole. This asymmetrical stepped structure allows the elastic body to exhibit a more rational deformation distribution when compressed, improving shock absorption efficiency and fatigue life. This structure works in cooperation with the main front-rear shock absorption system composed of the first elastic shock absorber 11 to complete the three-dimensional cushioning function of the entire holder in the front-rear, up-down, and left-right directions. The design, which involves pre-embedding the first nut insert 152, provides a reliable metal screw fixing base for the second fixing member 16, ensuring connection strength over long-term use.

[0044] As shown in Figure 1-8, in some embodiments, the smartphone clamp component 2 has the following configuration.

[0045] The housing consists of a front cover 21, an intermediate frame 22, and a rear cover 23, which are stacked and fixed together. The first connecting portion is a connecting pin 231 formed on the back surface of the rear cover 23. One end of the first elastic shock absorber 11 is fitted onto the outer circumference of the connecting pin 231, and the first fixing member 14 is inserted from the other end of the first elastic shock absorber 11 and locked into the connecting pin 231.

[0046] The device comprises a leg support portion 24 and two clamp arms 25, the leg support portion 24 being slidably mounted below the housing, and the two clamp arms 25 being slidably mounted on the left and right sides of the housing, respectively. Flexible pad members 26 are embedded in the mounting surface of the leg support portion 24 and the opposing surfaces of the two clamp arms 25, respectively.

[0047] At least one first guide rod 241 is connected to the leg support portion 24, and at least one second guide rod 251 is connected to the clamp arm 25. The first guide rod 241 and the second guide rod 251 are each inserted into the housing and positioned axially by spring washers.

[0048] The main body of the smartphone clamp component 2 is a housing in which a front cover 21, an intermediate frame 22, and a rear cover 23 are stacked in this order and fixed by fastening members (screws). The front cover 21 is located on the user side, and the rear cover 23 is located on the vehicle side. The first connection part is molded on the back of the rear cover 23 and is materialized as a connection pin 231 that protrudes outward. The connection pin 231 has a hollow structure and is provided with a screw hole inside. In the connection relationship, one end of the first elastic shock absorber 11 is directly fitted onto the outer surface of the connection pin 231, forming a surrounding configuration. The shaft portion of the first fixing member 14 is inserted into the interior from the other end of the first elastic shock absorber 11 opposite to the rear cover 23, and the fixing is completed when the threaded portion of the tip is screwed into the screw hole inside the connection pin 231.

[0049] The movable part of the smartphone clamp component 2 includes one leg support 24 and two clamp arms 25. The leg support 24 is mounted below the housing so as to be slidable in the vertical direction and can accommodate different smartphone lengths. The two clamp arms 25 are mounted on both the left and right sides of the housing so as to be slidable in the horizontal direction and can accommodate different smartphone widths. To prevent scratching the smartphone during clamping, soft, flexible pad members 26 are embedded in the mounting surface of the leg support 24 and the opposing surfaces of the two clamp arms 25. The sliding of the leg support 24 is achieved by at least one (two in the best design) first guide rod 241 connected to its rear end. The sliding of the clamp arms 25 is achieved by at least one (two in the best design) second guide rod 251 connected thereto. The first guide rod 241 is inserted inside the rear cover 23, and a corresponding guide rod slot is provided inside the rear cover 23. The second guide rod 251 is inserted inside the intermediate frame 22, and a corresponding guide rod hole is provided inside the intermediate frame 22. The first guide rod 241 and the second guide rod 251 are separated from each other and do not interfere with one another. Furthermore, spring washers are fitted to the ends of both rods to limit the extension range of the guide rods in the axial direction and prevent the guide rods from completely coming out of the housing.

[0050] The design of the connecting pin 231 cleverly integrates the first connection point between the clamping mechanism and the shock absorption mechanism 1. The first elastic shock absorber 11 is directly fitted onto the outer circumference of the connecting pin 231, and the first fixing member 14 is fixed from the inside, resulting in a compact structure and easy assembly. Both the leg support 24 and the clamp arm 25 slide and are positioned using a combination of a guide rod and a built-in spring washer, resulting in a simple and reliable structure with minimal space occupied inside the housing, ensuring sufficient space for the shock absorption mechanism 1 and other components. The installation of the flexible pad member 26 protects the smartphone's exterior from scratches and dents from the bottom mounting surface and the clamping surfaces on both sides, improving product safety and user experience.

[0051] As shown in Figure 1-8, in some embodiments, the smartphone clamp component 2 is further provided with a bottom locking mechanism 27, and the bottom locking mechanism 27 includes the following configuration.

[0052] The pressing block 271 is slidably mounted within the slide slot 232 of the rear cover 23, and the pressing block 271 has a pressing slot 272 formed therein that conforms to the outer shape of the first guide rod 241.

[0053] The first cam rod 273 is fixedly mounted within the slide slot 232, with one end extending through the pressing block 271 to the outside of the rear cover 23.

[0054] The first cam lever 274 is rotatably connected to the outer end of the first cam rod 273.

[0055] By operating the first cam lever 274, the pressing block 271 is driven via the first cam rod 273, and by pressing the first guide rod 241, the protruding length of the leg support portion 24 can be fixed.

[0056] A slide slot 232 is provided inside the rear cover 23, which communicates with the interior of the rear cover 23, and a portion of the first guide rod 241 is exposed. A pressing block 271 is slidably positioned inside the slide slot 232. The pressing block 271 has arc-shaped pressing slots 272 (the same number as the first guide rod 241) machined into it to match the circumferential surface contour of the first guide rod 241, thereby increasing the contact area. A first cam rod 273 is fixedly provided inside the slide slot 232, which slidably penetrates the interior of the pressing block 271, with one end extending to the outside of the rear cover 23. A first cam lever 274 is rotatably attached to the outer end of the first cam rod 273, forming an eccentric cam lock mechanism. The rotating end of the first cam lever 274 has a cam-shaped contour. When it is necessary to lock the position of the leg support 24, the first cam lever 274 is operated and rotated. The cam-shaped head of the first cam lever 274 undergoes axial displacement due to eccentric rotation, causing the pressing block 271 to slide along the first cam rod 273. This causes its pressing slot 272 to be firmly pressed against the outer wall of the corresponding first guide rod 241, and the protruding length of the leg support portion 24 is locked by the frictional force between the contact surfaces. When the first cam lever 274 is operated in the reverse direction, the cam-shaped head returns to its original position, and the pressing force against the pressing block 271 is released. The pressing block 271 releases the first guide rod 241, and the leg support portion 24 becomes freely adjustable up and down.

[0057] The leg support 24 is locked using a cam-driven lever-type quick-lock mechanism, making operation intuitive and quick. Locking or unlocking can be completed instantly with just one hand operation of the first cam lever 274, greatly improving the user experience when switching between smartphones of different sizes. The pressure block 271 and the two first guide rods 241 are fitted together via two arc-shaped pressure slots 272, ensuring a large friction locking area and strong locking force. This prevents the leg support 24 from shrinking due to vibrations during driving, guaranteeing that the smartphone maintains a stable clamp height regardless of road conditions.

[0058] As shown in Figure 1-8, in some embodiments, the smartphone clamp component 2 further includes a lateral locking mechanism 28, which comprises an adjustment screw 281, an axially fixed nut member 282, a sleeve 283, a rotation adjustment component 284, and a second cam lever 285. The nut member 282 is mounted within the intermediate frame 22 in a circumferentially fixed state.

[0059] The threaded portion of the adjustment screw 281 is screwed into the nut member 282, and its shaft portion (the smooth portion without threads) passes through the clamp arm 25 on one side and is fixed to the rotation adjustment part 284. The sleeve 283 is movably fitted onto the threaded portion of the adjustment screw 281 and is circumferentially positioned and engaged with the second cam rod 286. The second cam rod 286 slides through the other clamp arm 25, and the second cam lever 285 is rotatably connected to the outer end of the second cam rod 286.

[0060] When the rotation adjustment part 284 is turned in the loosening direction, the adjustment screw 281 becomes movable axially relative to the nut member 282, thereby releasing the pressure applied by the rotation adjustment part 284 to the clamp arm 25. At the same time, the end of the adjustment screw 281 pushes the sleeve 283 axially, releasing the pressure applied to the other clamp arm 25, and providing both clamp arms 25 with space to move outward for adjustment.

[0061] By rotating the rotation adjustment part 284 in the tightening direction, the two clamp arms 25 can be moved toward each other, and the second cam lever 285 is used to auxiliaryly lock the corresponding clamp arm 25.

[0062] The core components of this mechanism are an adjustment screw 281, a nut member 282, a sleeve 283, a rotation adjustment component 284, and a second cam lever 285. The nut member 282 is fixed circumferentially within a positioning groove in the intermediate frame 22, preventing both rotation and axial movement. The adjustment screw 281 is rotatably positioned inside one side of the intermediate frame 22. The threaded portion of the adjustment screw 281 is screwed into the fixed nut member 282, while the shaft portion on the opposite side (the smooth, threadless portion) passes through one of the clamp arms 25 and is fixed to the rotation adjustment component 284 (for example, by press-fit or key connection). When the rotation adjustment component 284 is rotated, the adjustment screw 281 also rotates in sync.

[0063] The sleeve 283 has a nut-shaped cylindrical structure with internal threads on its inner wall, and is externally fitted onto the threaded portion of the adjustment screw 281 and screwed into the threaded portion. The sleeve 283 is connected to the second cam rod 286. The cross-section of the second cam rod 286 is non-circular (e.g., rectangular), and the second cam rod 286 slides through the clamp arm 25 on the other side. The clamp arm 25 is guided by its second guide rod 251 and is therefore only movable in the front-rear direction and cannot rotate around the axis of the second cam rod 286. Because circumferential positioning is formed between the non-circular cross-section of the second cam rod 286 and the through-hole in the clamp arm 25, the second cam rod 286 cannot rotate relative to the clamp arm 25, and consequently the sleeve 283 connected to the second cam rod 286 cannot rotate either, and is only movable in the axial direction.

[0064] The second cam lever 285 is rotatably connected to the outer end of the second cam rod 286, forming an eccentric cam lock mechanism. During adjustment, when the rotation adjustment part 284 is rotated in the loosening direction, the adjustment screw 281 rotates synchronously. Since the nut member 282 is fixed, the adjustment screw 281 is displaced axially as it rotates, moving away from the nut member 282. This action produces two simultaneous effects. Firstly, the rotation adjustment part 284, which is fixed to the shaft portion (the part without threads), moves with the screw, releasing the pressure on one side of the clamp arm 25 and creating space for the clamp arm 25 to move outward. Secondly, although the threaded portion of the adjustment screw 281 rotates relative to the sleeve 283, the sleeve 283 cannot rotate due to the aforementioned transmission path, so due to the meshing action of the screw, the sleeve 283 moves axially away from the rotation adjustment part 284. This releases the pressure on the clamp arm 25 on the other side via the second cam rod 286, creating space for the clamp arm 25 to move outward. At this time, the rotation adjustment part 284 and the sleeve 283 move away from each other, and both clamp arms 25 become freely adjustable and released. When clamping, the rotation adjustment part 284 is rotated in the opposite direction to tighten it. The adjustment screw 281 rotates in the opposite direction and moves axially, moving the rotation adjustment part 284 and the sleeve 283 closer together, pushing the two clamp arms 25 from both sides and moving them closer together to clamp the smartphone. The second cam lever 285 functions as an independent auxiliary locking part. After locking by the rotation adjustment part 284, operating the second cam lever 285 again causes its cam-shaped head to push the corresponding clamp arm 25 further inward, increasing the locking force on that clamp arm 25.

[0065] By rotating a single rotation adjustment component 284, the double screw engagement between the adjustment screw 281, the fixing nut member 282, and the movable sleeve 283 (nut cylinder) is cleverly achieved to move the rotation adjustment component 284 and the sleeve 283 toward or toward each other, thereby synchronously releasing or clamping the two left and right clamp arms 25. The user can operate it with just one hand, making it simple and quick. The circumferential positioning of the sleeve 283 cleverly utilizes the characteristic that the clamp arm 25 itself is constrained and unable to rotate by the second guide rod 251, and this constraint is transmitted via the second cam rod 286 with a non-circular cross-section, thus eliminating the need for a separate positioning structure and reducing the number of parts.

[0066] The essence of its structure lies in the innovative combination of a screw-screw drive mechanism and a cam-type quick-lock mechanism, which provides a double lock. The first lock is a stable screw lock force generated by tightening the rotation adjustment part 284, and this lock force is maintained by the self-locking characteristics of the screw engagement between the adjustment screw 281, the nut member 282, and the sleeve 283. The lock force is large and durable. The second lock is a rapid cam lock force generated by operating the second cam lever 285, which can supplementarily enhance the locking effect. This double lock mechanism greatly improves the reliability of the clamp, effectively preventing the clamp arm 25 from loosening under severe vibrations, and ensuring the secure attachment of the smartphone in all road conditions.

[0067] A spring washer is fitted to the shaft portion (the smooth part without threads) of the adjustment screw 281, which limits the axial range of movement of the shaft portion relative to the clamp arm 25 through which it passes.

[0068] As shown in Figure 1-8, in some embodiments, a first ring gear 287 is provided on the end face of the rotation adjustment component 284 facing the clamp arm 25, and a second ring gear 288 is provided on the portion of the clamp arm 25 facing the end face.

[0069] When the rotation adjustment component 284 is tightened, the first ring gear 287 and the second ring gear 288 engage, thereby preventing the rotation adjustment component 284 from rotating in the reverse direction.

[0070] A first ring gear 287 is machined around the entire circumference of the end face of the rotation adjustment part 284 facing the clamp arm 25. This ring gear consists of multiple tooth-like protrusions evenly spaced in the circumferential direction. A second ring gear 288, which can mesh with the first ring gear 287, is also machined around the entire circumference of the front end face of the clamp arm 25 facing this ring gear. When the rotation adjustment part 284 is rotated to the locked position and the two clamp arms 25 firmly clamp the smartphone, the first ring gear 287 on the end face of the rotation adjustment part 284 and the second ring gear 288 on the end face of the clamp arm 25 mesh perfectly, forming a circumferential engagement between the teeth. During vehicle operation, the forces transmitted to the holder from road surface irregularities and engine vibrations mainly appear as irregular linear vibration components dispersed in multiple directions, such as longitudinal shocks, vertical vibrations, and lateral swaying. These forces are unlikely to form a rotational moment with a sustained and precise direction around the axis of the rotation adjustment part 284. Therefore, it is extremely difficult to accurately rotate the rotation adjustment part 284 by vibration alone, overcome the meshing engagement between the ring gears, and release the lock, thereby achieving a passive anti-loosening lock. On the other hand, if the user intentionally applies rotational force, relative slippage or elastic deformation of the tooth tips occurs between the ring gears, making it possible to smoothly release the lock.

[0071] By utilizing the physical characteristic that the direction of vibration and the force required for unlocking do not coincide, a clever and effective passive anti-loosening structure is constructed using the meshing of a pair of simple end-face ring gears. The principle of this anti-loosening is not to resist vibration with a large frictional force, but rather to make it difficult for the vibration force to "grasp" the precise rotational direction required for unlocking, thereby fundamentally suppressing the possibility of loosening caused by vibration force. This structure achieves reliable self-locking in vibrating environments solely through the meshing of teeth, without the need to add complex anti-loosening components such as springs or ratchets. At the same time, it maintains a good operability that allows the user to easily unlock by actively rotating it, and the structure is simple and highly reliable.

[0072] As shown in Figure 1-8, in some embodiments, the external mounting component 3 includes a ball connecting component 31. A ring-shaped guard 32 extends from the side of the shock-absorbing connection spot 15 opposite to the first connection portion, and a second nut insert 33 is fixed inside the ring-shaped guard 32.

[0073] The ball connecting component 31 has a ball portion 34 and a rod connecting portion 35. The rod connecting portion 35 is inserted into the internal hole of the ring-shaped guard 32 and fastened to the second nut insert 33 via a fixing screw 36, thereby achieving an integrated connection between the ball connecting component 31 and the shock absorption mechanism 1.

[0074] The external mounting component 3 is specifically a ball connector component 31, which is used to achieve 360-degree angle adjustment by engaging with a ball socket on an external support structure such as a handlebar, rearview mirror mounting base, or vehicle-mounted support structure. A ring-shaped guard 32 extends around the side of the shock-absorbing connection spot 15 opposite the first connection portion, forming an internal hole for housing the rod connector portion 35. A second nut insert 33 is fixed inside the ring-shaped guard 32, and this second nut insert 33 is pre-embedded within the wall of the ring-shaped guard 32. The ball connector component 31 consists of a ball portion 34 and a rod connector portion 35. The ball portion 34 is used to engage with an external ball socket, and the rod connector portion 35 is directly inserted into the internal hole of the ring-shaped guard 32 on the shock-absorbing connection spot 15 to make the connection. Subsequently, a fixing screw 36 is inserted from one end of the ball portion 34, passed through the inside of the ball connecting component 31, and reached the end of the rod connecting portion 35, where it is screwed and fastened with the second nut insert 33 inside the ring-shaped guard 32. This fixes the ball connecting component 31 and the shock-absorbing connection spot 15 together.

[0075] By directly integrating the ball connector 31 into the shock-absorbing connection spot 15 of the shock-absorbing mechanism 1, a unified design of the main components of the holder is achieved, eliminating the need for intermediate adapter parts. This results in a more compact structure, reduced number of parts, and smaller volume. This integrated connection method, by passing the fixing screw 36 through the ball connector 31 and directly screwing it into the second nut insert 33 in the shock-absorbing connection spot 15, provides extremely high rigidity and reliability to the connection between the ball connector 31 and the shock-absorbing mechanism 1, preventing loosening even after prolonged use. This ensures stability and a secure feel during the mounting and angle adjustment process of the entire holder.

[0076] As shown in Figure 1-8, in some embodiments, a metal bushing 37 is jointly embedded inside the ball portion 34 and the rod connection portion 35, and the fixing screw 36 passes through the metal bushing 37. A ball portion anti-slip covering member 38 is fitted to the outside of the ball portion 34. The front cover 21 is fixed to the intermediate frame 22 via a fastening member, and an anti-slip pad 29 is covered on the side of the front cover 21 opposite to the intermediate frame 22 to conceal the fastening member.

[0077] A metal bushing 37 is jointly embedded inside the ball connector 31, at the center of the ball portion 34 and the rod connector 35. This metal bushing 37 has a tubular structure, and the fixing screw 36 passes through the internal hole of this metal bushing 37 during installation. The metal bushing 37 enhances the internal structural strength of the plastic ball connector 31 and withstands the compressive force when the fixing screw 36 is fastened. A ball portion anti-slip covering member 38 is further fitted to the outside of the ball portion 34. This covering member is made of TPU material and provides surface friction and elastic deformation. In addition, in the smartphone clamp component 2, the front cover 21 is fixedly connected to the intermediate frame 22 by a fastening member (e.g., a screw). After assembly, an anti-slip pad 29 is covered on the outer surface of the front cover 21 opposite to the intermediate frame 22. This anti-slip pad 29 has two functions. First, it functions as a flexible contact surface with the back of the smartphone, and second, its covering area completely conceals the screw hole for attaching the fastening member on the front cover 21.

[0078] The metal bushing 37 functions as an internal skeleton, significantly improving the structural strength and fatigue life of the ball connector 31. This prevents stress concentration and fracture inside the ball joint, even during prolonged strong fastening or driving on rough roads. The externally fitted anti-slip covering member 38 for the ball portion not only provides comfortable rotational torque and positioning operation, but also increases the frictional force between the ball portion and the ball socket, allowing the ball portion to be stably locked at any angle within the ball socket, preventing angular displacement due to vibrations during driving. In addition, the anti-slip pad 29 on the front cover 21 provides flexible contact and anti-slip protection between the smartphone and the holder, preventing scratches on the smartphone's back cover and preventing it from slipping, while cleverly concealing the structural fastening components. As a result, no screw holes are exposed on the product's appearance, giving it a cleaner and more refined impression, improving the overall aesthetics and sense of unity of the product.

[0079] In some embodiments, both the first elastic shock absorber 11 and the second elastic shock absorber 12 are made of silicone material. By adjusting the Shore hardness of the silicone material and the placement of the elastic bodies at the four corners and circumferentially of the shock-absorbing frame 13, the natural frequency of the entire levitation system can be changed, thereby avoiding the resonant frequency points generated by motorcycle and automobile engines in the normal operating speed range. This makes it possible to effectively cancel out high-frequency resonances of the engine at specific frequencies. At the same time, the drum-shaped outer contour of the first elastic shock absorber 11 and the stepped sleeve-shaped structure of the second elastic shock absorber 12 absorb vibration energy through their own elastic deformation when subjected to impact from the road surface, protecting the optical image stabilization mechanism of the smartphone camera from vibration interference.

[0080] In some embodiments, the drum-shaped outer contour of the first elastic shock absorber 11 and the stepped sleeve-shaped contour of the second elastic shock absorber 12 cause them to exhibit multi-stage deformation characteristics when subjected to vibrations of different intensities. When the road surface irregularities are relatively minor, only the thin-walled portion of the elastic body deforms, providing a softer shock absorption effect. As the impact intensity increases, the thick-walled portion of the elastic body also participates in the deformation, exhibiting stronger support force and energy absorption capacity. This allows the shock absorption force to be automatically adjusted according to the vibration intensity, achieving an optimized shock absorption effect for different road surface conditions.

[0081] In some embodiments, the clamp arm 25 can accommodate smartphones ranging from 4.7 inches to 7.2 inches via sliding adjustment by the second guide rod 251. The overall design of the holder is minimal and refined, and does not obstruct the smartphone camera when clamped. The ball connector 31 of the external mounting part 3 is a standard part and can be connected to a ball socket structure on the handlebars of a motorcycle, electric bicycle, or bicycle, to the mounting base of a rearview mirror mounting base, or even to an in-car holder, thus accommodating a variety of mounting scenarios.

[0082] As described above, the first elastic shock absorbers 11, symmetrically arranged at the four corners, and the second elastic shock absorbers 12, evenly arranged in the circumferential direction, work together to form a floating elastic connection in three directions—front-to-back, up-and-down, and left-to-right—between the first and second connection parts, creating a multi-dimensional, multi-point three-dimensional buffer space. The first elastic shock absorbers 11 are specialized in absorbing vertical shocks perpendicular to the smartphone screen and high-frequency resonances of the engine, while the second elastic shock absorbers 12 absorb vibrations within the screen plane and lateral centrifugal forces. By working together, they filter vibrations from all directions, effectively protecting the optical image stabilization mechanism of the smartphone camera. The entire shock absorption mechanism 1 is built into the force transmission path of the holder via the first and second connection parts, eliminating the need for additional external modules and resulting in a compact, integrated structure.

[0083] Finally, it should be explained that the examples described above are merely excellent embodiments of the utility model and do not limit it. While the utility model has been described in detail with reference to the aforementioned embodiments, a person skilled in the art can still modify the inventions described in the embodiments above, or make equivalent substitutions for some of their technical features. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the utility model shall all be covered by the utility model.
