Description

Technical Field

[0001] The utility model relates to the field of mobile phone holders, and particularly to a mobile phone holder with step - by - step adjustable clamping. Background Art

[0002] With the wide use of smart phones, mobile phone holders play an increasingly important role in daily life. However, there are many inconveniences and potential problems in the design of traditional mobile phone holders on the current market.

[0003] Firstly, traditional mobile phone holders usually require users to press the push blocks on both sides to the bottom before the two clamping arms can be opened and maintained in the open state. Although this design is convenient for placing the mobile phone, the opening size is often fixed. To adapt to mobile phones of various sizes, manufacturers usually tend to design larger opening sizes. However, this is not friendly to small - sized mobile phones because the too - large opening may cause the mobile phone to be unstable in the holder and easy to shake.

[0004] Moreover, traditional mobile phone holders adopt the design of clamping after the clamping arms are opened to the maximum extent. Although this design is convenient for users to put the mobile phone into the holder, during the clamping process, since the clamping arms quickly tighten from the maximum opening state, it often generates a large impact force on the mobile phone. This impact force may cause damage such as scratches, impacts or even cracks to the side screen or other vulnerable parts of the mobile phone.

[0005] Secondly, when users want to take out the mobile phone, they also need to push the push blocks on both sides to the bottom to keep the clamping arms in the open state. However, after the mobile phone is assembled, since the mobile phone itself occupies a certain space, it may hinder the complete pressing of the push blocks, thus increasing the difficulty of taking out the mobile phone.

[0006] In summary, the design of traditional mobile phone holders has obvious deficiencies in aspects such as opening size, difficulty of taking out the mobile phone, and clamping method. To solve these problems, a new design scheme of mobile phone holders is urgently needed, aiming to provide a more flexible and convenient clamping method and a better user experience. Summary of the Invention

[0007] To solve the above problems, the utility model provides a mobile phone holder with step - by - step adjustable clamping, providing a more flexible and convenient clamping method and a better user experience. Such a design scheme will be able to adapt to mobile phones of different sizes, simplify the operation of taking out the mobile phone, and improve the overall convenience and comfort of use.

[0008] To achieve the above object, the technical solution adopted by the present utility model is as follows: A mobile phone holder with stepwise adjustable clamping, comprising an installation housing, a left clamping arm, a right clamping arm, and a pawl device. The left clamping arm and the right clamping arm are both slidably assembled in the installation housing. Rack structures are provided on both the left clamping arm and the right clamping arm, and a plurality of rack teeth are provided on the rack structures. Among them, the pawl device is elastically assembled in the installation housing, and a plurality of pawl teeth on the pawl device are engaged with the rack teeth, thereby allowing the left clamping arm and the right clamping arm to move away from each other, but opposing the left clamping arm and the right clamping arm to move closer to each other.

[0009] Furthermore, it further includes a first elastic member and a second elastic member. The pawl device is assembled in the installation housing through the second elastic member. When the pawl teeth are disengaged from the rack teeth, the left clamping arm and the right clamping arm are brought closer to each other and clamped through the first elastic member.

[0010] Furthermore, each rack tooth includes a first vertical surface and a first ramp surface to form a shark fin-shaped structure; each pawl tooth of the pawl includes a second vertical surface and a second ramp surface to form a shark fin-shaped structure.

[0011] Furthermore, the installation housing includes an installation bottom plate and an installation panel. The installation panel covers the surface of the installation bottom plate. An installation inner cavity is formed between the installation panel and the installation bottom plate, and the left clamping arm, the right clamping arm, and the pawl device are all assembled in the installation inner cavity.

[0012] Furthermore, the left clamping arm has a "Z" - shaped structure, including a clamping block and a sliding block arranged in the installation inner cavity. One end of the clamping block is bent to form a clamping plate extending outside the installation inner cavity. The bottom of the other end of the clamping block is connected to the sliding block, and rack teeth are provided at the bottom of the sliding block. A pushing block extending outside the installation cavity is also connected to the end of the sliding block; in addition, the structure of the right clamping arm is a mirror image of the structure of the left clamping arm, and the left clamping arm and the right clamping arm are stacked.

[0013] Furthermore, a first waist - shaped hole extending in the horizontal direction is formed on the surface of each sliding block, and a number of second teeth are provided inside the first waist - shaped hole; a synchronous movement gear is assembled in the first waist - shaped holes of the left clamping arm and the right clamping arm, and the synchronous movement gear is engaged with the second teeth of the two first waist - shaped holes.

[0014] Furthermore, a rotating shaft column is provided on the bottom surface of the installation panel, and the synchronous movement gear is sleeved on the rotating shaft column.

[0015] Further, the pawl device includes a mounting plate, where pawl teeth are provided on the top of the mounting plate, and a second waist-shaped hole extending in the vertical direction is provided on the surface of the mounting plate. A first mounting post is provided at the top of the second waist-shaped hole; a first mounting slot adapted to the mounting plate is provided on the bottom surface of the mounting panel. By sliding the mounting plate along the direction of the first mounting slot, the second elastic member between the second mounting convex block and the first mounting post is compressed.

[0016] Further, a bottom support plate extending out of the mounting cavity is also provided at the end of the mounting plate.

[0017] Further, clamping arm slots for mounting the left clamping arm and the right clamping arm are also provided on the bottom surface of the mounting panel. A third waist-shaped hole is provided on the surface of the clamping block, and a second mounting post is convexly provided on the surface of the clamping arm slot, and the second mounting post passes through the corresponding third waist-shaped hole.

[0018] The beneficial effects of the present utility model are as follows: Through the precise engagement between the pawl device and the rack teeth, the user can gradually open the left clamping arm and the right clamping arm according to needs, rather than only being able to open them to the maximum extent at one time. This function of gradually opening enables the bracket to more precisely adapt to mobile phones of different sizes, and at the same time provides the user with more flexibility and control.

[0019] The design solution of the present application allows the user to precisely adjust the distance between the clamping arms before placing the mobile phone through a step-by-step adjustment and self-locking mechanism, thus avoiding the process of opening to the maximum and then clamping. This significantly reduces the impact force generated on the mobile phone during the clamping process and effectively protects the mobile phone from potential damage.

[0020] Traditional brackets usually only have a fixed opening and closing degree, while the design of the present application allows the user to customize the opening and closing degree according to needs. This design not only meets the user's demand for personalization but also makes the bracket more user-friendly and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0031] Please refer to Figures 1-9 As shown, the present utility model relates to a mobile phone holder with stepwise adjustable clamping, including a mounting housing, a left clamping arm 3, a right clamping arm 4, and a pawl device 5. The left clamping arm 3 and the right clamping arm 4 are both slidably fitted in the mounting housing. Rack structures are provided on both the left clamping arm 3 and the right clamping arm 4, and a plurality of rack teeth 322 are provided on the rack structures. Among them, the pawl device 5 is elastically fitted in the mounting housing, and a plurality of pawl teeth 53 on the pawl device 5 are engaged with the rack teeth 322, thereby allowing the left clamping arm 3 and the right clamping arm 4 to move in a direction away from each other, but opposing the left clamping arm 3 and the right clamping arm 4 to move in a direction close to each other.

[0032] Please refer to Figure 2 As shown, through the precise engagement of the pawl device 5 and the rack teeth 322, the user can open the left clamping arm 3 and the right clamping arm 4 step by step according to needs, rather than only being able to open them to the maximum extent at one time. This stepwise opening function enables the holder to more precisely adapt to mobile phones of different sizes, and at the same time provides the user with more flexibility and control.

[0033] Moreover, when traditional mobile phone holders clamp the phone, since they need to open the clamping arms to the maximum extent before clamping, they often generate a large impact force on the phone. This impact force may damage the side screen or other vulnerable components of the phone. The design solution of this application allows users to precisely adjust the distance between the clamping arms before placing the phone through a step-by-step adjustment and self-locking mechanism, thus avoiding the process of opening to the maximum and then clamping. This significantly reduces the impact force generated on the phone during clamping and effectively protects the phone from potential damage.

[0034] Traditional holders usually have a fixed opening and closing degree, while the design of this application allows users to customize the opening and closing degree according to their needs. This design not only meets the user's demand for personalization but also makes the holder more user-friendly and convenient. Since the engagement between the pawl device 5 and the rack teeth 322 has self-locking property, once the opening and closing degree is set, the holder can maintain a stable state and will not be easily changed by external factors (such as vibration or touch). This stability and safety are crucial for protecting the phone, especially when used in a moving vehicle or other dynamic environments. By providing the function of step-by-step opening and maintaining, the holder design significantly improves the user experience. Users no longer need to laboriously adjust the holder to fit the phone but can easily find the most suitable opening and closing degree through step-by-step adjustment.

[0035] Furthermore, it also includes a first elastic member 15 and a second elastic member 54. The pawl device 5 is assembled in the installation housing through the second elastic member 54. When the pawl teeth 53 are disengaged from the rack teeth 322, the left clamping arm 3 and the right clamping arm 4 are brought closer to each other and clamped through the first elastic member 15.

[0036] Through the setting of the first elastic member 15, when the pawl teeth 53 are disengaged from the rack teeth 322, the left clamping arm 3 and the right clamping arm 4 can automatically approach each other by virtue of the restoring force of the first elastic member 15, thereby realizing the clamping of the phone. This design eliminates the trouble of users manually adjusting the clamping arms and improves the convenience of use.

[0037] The second elastic member 54 not only enables the pawl device 5 to be elastically assembled in the mounting housing, but also provides necessary buffering and reset functions. When the pawl device 5 interacts with the rack structure, the second elastic member 54 can absorb impacts and vibrations, protecting the mobile phone from damage. At the same time, after the user adjusts the position of the clamping arm, the second elastic member 54 can also help the pawl device 5 to quickly reset. By reasonably designing the elastic force of the first elastic member 15 and the moving range of the clamping arm, it can be ensured that the mobile phone is stably clamped on the bracket, and can remain stable even in a bumpy or vibrating environment. This stability is crucial for protecting the mobile phone and the safety of the user. The automatic clamping function and the elastic reset mechanism greatly simplify the user operation, making it easier and faster to place and remove the mobile phone. At the same time, due to the automation and improved stability of the clamping process, users will be more reassured and satisfied when using the bracket.

[0038] Please refer to Figures 8-9 As shown, further, each rack tooth 322 includes a first vertical surface 3222 and a first ramp surface 3221 to form a shark fin-shaped structure; each pawl tooth 53 of the pawl device 5 includes a second vertical surface 531 and a second ramp surface 532 to form a shark fin-shaped structure. When the left clamping arm 3 or the right clamping arm 4 moves outwards, the first ramp surface 3221 of the rack tooth 322 will contact the second ramp surface 532 of the pawl tooth 53. As the left clamping arm 3 and the right clamping arm 4 continue to move, the pawl tooth 53 will move down along the ramp surface of the rack tooth 322. When the movement is in place, the first vertical surface 3222 of the rack tooth 322 will be in close contact with the second vertical surface 531 of the pawl tooth 53 under the action of the first elastic member 15. At this time, the pawl device 5 is in a locked state, preventing the clamping arm from moving inwards.

[0039] Please refer to Figures 6-7 As shown, further, the mounting housing includes a mounting base plate and a mounting panel 1, wherein the mounting panel 1 covers the surface of the mounting base plate, and an installation cavity is formed between the mounting panel 1 and the mounting base plate, and the left clamping arm 3, the right clamping arm 4, and the pawl device 5 are all assembled in the installation cavity.

[0040] The combination of the mounting base plate and the mounting panel 1 forms a sturdy housing, providing a stable mounting environment for the left clamping arm 3, the right clamping arm 4, and the pawl device 5. The existence of the mounting inner cavity enables these components to be assembled tightly and securely together, reducing the risk of damage caused by external impacts or vibrations during use. This split design makes the assembly process simpler and more convenient. The mounting base plate and the mounting panel 1 can be pre-treated separately, such as pre-installing components like the clamping arms and the pawl device 5, and then covering the two together to complete the assembly of the entire bracket. This design also facilitates later maintenance and component replacement. If a component needs to be replaced or repaired, simply opening the mounting panel 1 allows easy access to the internal mechanism.

[0041] Please refer to Figures 2-4 As shown, further, the left clamping arm 3 has a "Z" - shaped structure, including a clamping block 33 and a sliding block 32 arranged in the mounting inner cavity. One end of the clamping block 33 is bent to form a clamping plate 34 extending outside the mounting inner cavity. The bottom of the other end of the clamping block 33 is connected to the sliding block 32, and a rack tooth 322 is provided at the bottom of the sliding block 32. The end of the sliding block 32 is also connected to a pushing block 31 extending outside the mounting cavity. Additionally, the structure of the right clamping arm 4 is a mirror image of the structure of the left clamping arm 3, and the left clamping arm 3 and the right clamping arm 4 are stacked. The structure of the right clamping arm 4 is a mirror image of the left clamping arm 3, and they are symmetric in design and function. This design ensures that the left and right clamping arms 4 can provide uniform force and stability when clamping the mobile phone. The left clamping arm 3 and the right clamping arm 4 are stacked, further enhancing the clamping stability and reliability, and at the same time saving occupied space.

[0042] Please refer to Figure 3 As shown, further, each sliding block 32 has a first waist - shaped hole 321 extending in the horizontal direction on its surface, and a number of second teeth 3211 are provided inside the first waist - shaped hole 321. Synchronous moving gears 6 are fitted in the first waist - shaped holes 321 of the left clamping arm 3 and the right clamping arm 4, and the synchronous moving gears 6 mesh with the second teeth 3211 of the two first waist - shaped holes 321. Further, a rotating shaft column 13 is provided on the bottom surface of the mounting panel 1, and the synchronous moving gears 6 are sleeved on the rotating shaft column 13.

[0043] The first kidney-shaped hole 321 formed on the surface of each sliding block 32 not only provides space for the synchronous movement of the gear 6, but also meshes with the synchronous movement gear 6 through the second tooth 3211 provided on its inner side, achieving precise transmission. It is ensured that when the synchronous movement gear 6 rotates, it can drive the sliding blocks 32 of the left clamping arm 3 and the right clamping arm 4 to move synchronously, thus maintaining the consistency of the two clamping arms. The rotating shaft column 13 on the bottom surface of the mounting panel 1 provides stable support and positioning for the synchronous movement gear 6, ensuring the smoothness and accuracy of the gear during rotation. The design of the rotating shaft column 13 also enables the synchronous movement gear 6 to flexibly transmit power between the left clamping arm 3 and the right clamping arm 4, achieving synchronous adjustment of the two clamping arms.

[0044] Please refer to Figure 5 As shown, further, the pawl device 5 includes a mounting plate 51. A pawl tooth 53 is provided on the top of the mounting plate 51. A second kidney-shaped hole 511 extending in the vertical direction is provided on the surface of the mounting plate 51. A first mounting post 512 is provided at the top of the second kidney-shaped hole 511. A first mounting slot 12 adapted to the mounting plate 51 is provided on the bottom surface of the mounting panel 1. By sliding the mounting plate 51 along the direction of the first mounting slot 12, the second elastic member 54 located between the second mounting protrusion and the first mounting post 512 is compressed.

[0045] The mounting plate 51 is the main support structure of the pawl device 5, which bears the pawl tooth 53 and other related components. The pawl tooth 53 is provided on the top of the mounting plate 51, which is the key component interacting with the rack tooth 322 to achieve the locking and unlocking functions. The second kidney-shaped hole 511 provided on the surface of the mounting plate 51 extends in the vertical direction, which provides space for the installation and compression of the second elastic member 54. The first mounting post 512 provided at the top of the second kidney-shaped hole 511 is the fixed point of one end of the elastic member. It acts together with the second mounting protrusion on the mounting panel 1 to compress the second elastic member 54. A first mounting slot 12 adapted to the mounting plate 51 is provided on the bottom surface of the mounting panel 1, which provides precise positioning for the assembly of the pawl device 5. The design of the first mounting slot 12 enables the mounting plate 51 to slide along the slot direction, which is the key action to achieve unlocking and clamping.

[0046] Further, a bottom support plate 52 extending out of the installation cavity is also provided at the end of the mounting plate 51.

[0047] The bottom support plate 52 extends out an installation inner cavity, providing a user with an intuitive and stable mobile phone placement area. When the user places the mobile phone on the bottom support plate 52, at the same time, the user can press down the bottom support plate 52 with the mobile phone. The downward movement of the mounting plate 51 causes the pawl device 5 to disengage from the rack teeth 322, enabling the left and right clamping arms to hold the mobile phone tightly under the action of the first elastic member 15. This design not only simplifies the user's operation but also ensures that the mobile phone can be firmly fixed on the bracket.

[0048] The user does not need to perform complex adjustments or operations. Just place the mobile phone on the bottom support plate 52, and the bracket can automatically adapt and clamp the mobile phone. This convenience and automatic adaptability greatly enhance the user experience. The design of the bottom support plate 52 not only enhances the practicality of the bracket but also ensures the stability of the mobile phone on the bracket.

[0049] Please refer to Figure 6 As shown, further, the bottom surface of the installation panel 1 is also provided with arm slots 11 for mounting the left clamping arm 3 and the right clamping arm 4. The surface of the clamping block 33 is provided with a third waist-shaped hole 331. The surface of the arm slot 11 is convexly provided with a second fitting post 14, and the second fitting post 14 passes through the corresponding third waist-shaped hole 331. Through the design of the third waist-shaped hole 331, the left and right clamping arms can move freely within a certain range to adapt to mobile phones of different widths. The user only needs to simply slide the clamping arm to the appropriate position and then fix it. Although the clamping arm can move, the design of the second fitting post 14 passing through the third waist-shaped hole 331 still ensures a firm connection between the clamping arm and the installation panel 1. This connection method ensures that the clamping arm will not accidentally fall off or shift during use.

[0050] Please refer to Figure 3 As shown, further, elastic member receiving grooves 35 are provided on the back surfaces of the corresponding clamping blocks 33 of the left clamping arm 3 and the right clamping arm 4. Third fitting posts 351 are provided on both of the two elastic member receiving grooves 35, and both ends of the first elastic member 15 are respectively fitted with the two third fitting posts 351. Elastic member receiving grooves 35 are provided on the back surfaces of the corresponding clamping blocks 33 of the left clamping arm 3 and the right clamping arm 4. The purpose of these grooves is to accommodate and fix the elastic member (i.e., the first elastic member 15).

[0051] The elastic member receiving groove 35 ensures that the elastic member can be stably mounted on the clamping block 33 without shifting or falling off during use. Third fitting posts 351 are provided on both of the two elastic member receiving grooves 35, and these fitting posts are used to fix both ends of the elastic member. The third fitting posts 351 are designed as protrusions or threaded posts so as to firmly connect with both ends of the elastic member. Both ends of the first elastic member 15 are respectively fitted with the two third fitting posts 351, forming an elastic connection. This elastic connection enables a certain tension and resilience between the left clamping arm 3 and the right clamping arm 4, which helps to clamp the mobile phone and prevent it from slipping. Through this design, the left clamping arm 3 and the right clamping arm 4 can maintain a certain clamping force under the action of the elastic member, ensuring that the mobile phone will not shake or slip during use. At the same time, the introduction of the elastic member also increases a certain buffering effect, preventing damage to the mobile phone due to external impacts.

[0052] Please refer to Figures 1-9 as shown, for the working principle of the specific clamping mechanism

[0053] 1. Initial state: The user pushes the push blocks 31 on both sides. This action causes the left clamping arm 3 and the right clamping arm 4 to move away from each other simultaneously.

[0054] 2. Step - by - step adjustment and engagement: During the movement of the left clamping arm 3 and the right clamping arm 4, the pawl teeth 53 will gradually engage with the rack teeth 322. This design realizes the function of step - by - step adjustment, allowing the user to precisely control the distance between the clamping arms. The engagement of the pawl teeth 53 with the rack teeth 322 not only provides the adjustment function but also ensures the stability and accuracy of the adjustment. Once the user sets the desired distance between the clamping arms, the engagement of the pawl device 5 with the rack teeth 322 has a self - locking property (specifically, the first elastic member generates an inward pulling force, causing the first vertical surface 3222 to fit with the second vertical surface 531), and can maintain the current set state. This self - locking mechanism ensures that the bracket can remain stable after being set and will not easily change the distance between the clamping arms due to external vibrations, touches, or other factors.

[0055] 3. Placing the mobile phone: When the distance between the clamping arms is adjusted to the appropriate position and locked, when the user places the mobile phone on the bottom support plate 52, at the same time the user can press down the bottom support plate 52 with the mobile phone. The downward movement of the fitting plate 51 causes the pawl device 5 to disengage from the rack teeth 322, enabling the left and right clamping arms to hold the mobile phone tightly under the action of the first elastic member 15. At the same time, the bottom support plate 52 will reset under the action of the second elastic member 54.

[0056] 4. Using the mobile phone: The mobile phone is safely placed on the bracket, and the user can use it with confidence without worrying about the mobile phone slipping or shifting.

[0057] 5. Adjust or remove the mobile phone: If the user needs to adjust the distance between the clamping arms or replace the mobile phone, the pushing block 31 can be pushed again, and then the position of the clamping arms can be readjusted. After the adjustment is completed, release the pushing block 31, and the ratchet teeth 53 will engage with the rack teeth 322 again to lock the new distance between the clamping arms.

[0058] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
