Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electronic equipment protection, specifically a buffer protection device for mobile phones. BACKGROUND

[0002] The popularity of smartphones has driven the growth of demand for mobile phone protection devices. However, existing protection devices rely on simple physical buffer structures, making it difficult to achieve all-around protection in complex drop scenarios, resulting in easy damage to the phone and limited user experience.

[0003] After searching, a kind of anti-falling mobile phone shell with publication number CN110278316B was found, published on March 23, 2021. The design achieves rolling buffer effect by setting up a roller device (including rubber wheel) on the outside of the mobile phone shell, thereby reducing the risk of scratching the mobile phone on uneven road surfaces such as sand. However, it mainly relies on the rolling buffer of the rubber wheel, and the protection capability for vertical impact force (such as direct impact of the front or back of the mobile phone on the ground) is weak, which is difficult to meet the needs of complex drop scenarios, and the scope of application is limited.

[0004] After searching, a kind of anti-vibration anti-falling mobile phone protection blister tray with publication number CN115477086B was found, published on November 21, 2023. The product uses a clamping frame and multiple springs to squeeze and fix the two sides of the mobile phone, and uses a rubber column to resist the inner wall of the clamping frame to achieve buffer protection. Although this design can reduce damage caused by vibration or slight drop, it is mainly suitable for fixed scenarios in the blister tray, and is difficult to cope with high drop or strong impact that may occur during daily handheld or carrying, and the protection performance needs to be further improved.

[0005] The above problems show that the traditional mobile phone protection device has insufficient ability to provide all-around buffer protection in complex drop scenarios, and there is an urgent need for a new solution that is intelligent, efficient and adaptable to changing environments.

Specific implementation

[0025] The utility model provides a kind of buffer protection device for mobile phone, the specific implementation of the utility model is explained in detail below in conjunction with drawings. Figure 1 The overall structure schematic view of the utility model shows the composition and layout relationship of main body frame 1, buffer shell 2, multilayer buffer assembly 6, intelligent adjusting mechanism 10, clamping assembly 11, anti-collision protrusion 15 and auxiliary supporting foot 16.

[0026] As Figure 1 Indicated, main body frame 1 is as the core load-bearing component of entire buffer protection device, its appearance is rectangular frame body, is made of high-strength lightweight material, ensures the rigidity and durability of overall structure. Main body frame 1 is installed with buffer shell 2 on the outside by bolt or other fixed mode, and buffer shell 2 includes outer shell 3, inner shell 4 and the elastic support column 5 being arranged between the two. Buffer gap is formed between outer shell 3 and inner shell 4, and elastic support column 5 is evenly distributed in the buffer gap, and one end of elastic support column 5 is fixed on the inner wall of outer shell 3, and the other end is fixed on the outer wall of inner shell 4. Elastic support column 5 is made of flexible high molecular material, it has certain compression recovery ability in axial direction, and it has certain bending deformation ability in radial direction, can effectively disperse impact force and reduce the energy transmitted to inner shell 4.

[0027] Multilayer buffer assembly 6 is arranged in the inner cavity of buffer shell 2, as Figure 3As shown, the multi-layer buffer assembly 6 is composed of a first buffer layer 7, a second buffer layer 8 and a third buffer layer 9 stacked in turn. The first buffer layer 7 is composed of a plurality of honeycomb units, the inside of which is filled with elastic particles that can absorb the impact force in the vertical direction and gradually dissipate the energy through the deformation of the honeycomb structure. The second buffer layer 8 is composed of a number of spring arrays, each of which is fixed between the first buffer layer 7 and the third buffer layer 9. When impacted, the spring arrays can produce a compression recovery effect, further absorbing the remaining impact energy. The third buffer layer 9 is a whole piece of high-density foam board, the surface of which is uniformly distributed with a plurality of air holes. This design not only improves the energy absorption effect, but also enhances the heat dissipation performance to avoid affecting the service life due to heat accumulation inside the device.

[0028] A receiving cavity is provided at the central position inside the main frame 1, and a smart adjusting mechanism 10 is provided around the receiving cavity, as shown in Figure 4 The smart adjusting mechanism 10 includes a driving module, a transmission module and a positioning module. The driving module is fixedly installed at the four corners of the receiving cavity, and the output end of the driving module is connected to the clamping assembly 11 through the transmission module. The transmission module includes a gear set and a rack, the gear set is fixed on the output shaft of the driving module, and the rack is slidingly installed along the inner wall of the receiving cavity. When the driving module is started, the gear set drives the rack to move, thereby achieving dynamic adjustment of the clamping assembly 11. The positioning module includes a photoelectric sensor and a limit switch. The photoelectric sensor is installed on the inner wall of the receiving cavity and is used to detect the position information of the mobile phone. The limit switch is fixed at the end of the rack and is used to control the stroke range of the rack to prevent excessive movement from causing damage to the equipment.

[0029] The clamping assembly 11 includes a fixed clamping plate 12, a movable clamping plate 13 and an elastic gasket 14, as shown in Figure 4 The fixed clamping plate 12 is fixedly installed on the inner wall of one side of the receiving cavity, and the movable clamping plate 13 is connected to the driving module through the transmission module and can move back and forth according to the instructions of the smart adjusting mechanism 10. The elastic gasket 14 is pasted on the inner side surface of the fixed clamping plate 12 and the movable clamping plate 13. The material of the elastic gasket 14 is silicone or rubber, and the surface thereof is provided with anti-slip texture. This design can increase the friction between the clamping assembly 11 and the mobile phone, thereby ensuring that the mobile phone does not displace during the falling process.

[0030] Anti-collision protrusions 15 are provided on the top and bottom of the main frame 1, as shown in Figure 5 The anti-collision protrusions 15 are in the shape of a hemisphere, the inside of which is filled with shock-absorbing material, and the outside is covered with a wear-resistant coating. The anti-collision protrusions 15 are fixed at the upper and lower ends of the main frame 1 by bolts. When the mobile phone is subjected to an impact force in the vertical direction, the anti-collision protrusions 15 can first contact the ground and disperse the impact force to other parts of the main frame 1, thereby reducing the energy directly transmitted to the mobile phone.

[0031] The outer side of the buffer shell 2 is symmetrically provided with auxiliary support feet 16, as Figure 5 As shown, the bottom of the auxiliary support feet 16 is mounted with rolling bearings 17, and the auxiliary support feet 16 are connected with the outer wall of the buffer shell 2 through hinges, and the unfolding angle thereof can be manually adjusted. When the device is placed on the desktop, the auxiliary support feet 16 can provide additional support force to enhance stability, and the design of the rolling bearings 17 makes the device more convenient to move when needed.

[0032] In actual use, when the mobile phone is subjected to a vertical impact force, the impact force is first transmitted to the outer shell 3 of the buffer shell 2, and the impact force is dispersed to the inner shell 4 through the axial compression recovery capability of the elastic support column 5; then, the impact force is further transmitted to the multi-layer buffer assembly 6, and the remaining impact force is gradually resolved through the honeycomb unit elastic particle filling of the first buffer layer 7, the spring array compression recovery of the second buffer layer 8, and the energy absorption of the high-density foam board of the third buffer layer 9. When the mobile phone is subjected to a lateral impact force, the radial bending deformation capability of the elastic support column 5 can effectively absorb and disperse the impact force, thereby avoiding the mobile phone directly bearing the impact.

[0033] In addition, the intelligent adjustment mechanism 10 detects the position information of the mobile phone through the photoelectric sensor, and controls the transmission module to drive the clamping assembly 11 to dynamically adjust, so that the distance between the movable clamping plate 13 and the fixed clamping plate 12 is always kept within the optimal range. The anti-skid texture design of the elastic gasket 14 further enhances the friction between the clamping assembly 11 and the mobile phone, preventing the mobile phone from shifting during the falling process. The arrangement of the anti-collision protrusion 15 and the auxiliary support feet 16 further enhances the impact resistance of the device when falling, and improves the stability of the device when placed on the desktop.

[0034] The above is the specific embodiment of the present application, through the detailed description of the structure design and operation principle, it can be clearly understood that the present application solves the problems existing in the prior art and realizes the goal of omnidirectional buffer protection and dynamic adaptive adjustment.

[0035] In order to better enable the relevant personnel in the technical field to fully understand and implement the present application, the specific implementation principle of the present application is further supplemented in the following with reference to a specific application scenario.

[0036] In actual use, when the phone accidentally falls from a high place, the outer shell 3 of the buffer shell 2 first contacts the ground. After the outer shell 3 is impacted, the impact force is initially dispersed by the elastic support column 5. Because the elastic support column 5 is made of flexible high polymer material, its axial compression recovery capability can transmit the vertical impact force to the inner shell 4, and its radial bending deformation capability effectively absorbs the lateral impact force. The key to this process lies in the structural design of the elastic support column 5, which is uniformly distributed in the buffer gap between the outer shell 3 and the inner shell 4, ensuring that the impact force is not concentrated on a certain point, thereby avoiding the phone directly bearing excessive impact.

[0037] Subsequently, the impact force is further transmitted to the multi-layer buffer assembly 6. The honeycomb cells in the first buffer layer 7 are filled with elastic particles, which can deform under the action of impact force and dissipate energy through the gradual compression of the honeycomb structure. The advantage of this design lies in the geometric properties of the honeycomb cells, which together with the filling of elastic particles achieve effective absorption of vertical impact force. Then, the remaining impact force is transmitted to the second buffer layer 8, where the spring array further plays a role. The two ends of each spring are fixed between the first buffer layer 7 and the third buffer layer 9, and when impacted, the spring array produces a compression recovery effect, thereby absorbing the remaining impact energy. Finally, the high-density foam board of the third buffer layer 9 further absorbs energy through the uniformly distributed air holes on its surface, while the design of the air holes also enhances the heat dissipation performance, avoiding the impact of heat accumulation inside the device on the service life.

[0038] Under the action of the intelligent adjustment mechanism 10, the clamping assembly 11 can dynamically adjust according to the actual position of the phone. After the photoelectric sensor detects the position information of the phone, the drive module is started and moves the rack through the transmission module, so that the movable clamp plate 13 approaches or moves away from the fixed clamp plate 12. During the horizontal sliding of the rack along the inner wall of the containing cavity, the limit switch ensures that its travel range does not exceed the preset value, preventing excessive movement from causing damage to the equipment. The distance between the movable clamp plate 13 and the fixed clamp plate 12 is always kept within the optimal range, and the anti-slip texture design of the elastic gasket 14 further enhances the friction between the clamping assembly 11 and the phone, thereby ensuring that the phone does not displace during the falling process.

[0039] In addition, the anti-collision protrusion 15 plays a key role when the phone falls. When the phone is subjected to a vertical impact force, the anti-collision protrusion 15 first contacts the ground and compresses the shock-absorbing material inside, thereby dispersing the impact force to other parts of the main body frame 1. This design greatly reduces the energy directly transmitted to the phone, improving the impact resistance. The auxiliary support foot 16 provides additional stability when the device is placed on a table. When the device needs to be moved, the design of the rolling bearing 17 makes it easier to slide, and the hinge connection allows the user to manually adjust the deployment angle of the auxiliary support foot 16 to adapt to different use scenarios.

[0040] Through the synergistic effect of the above steps, the utility model realizes the goal of all-around buffer protection. Whether it is a vertical or lateral impact force, it can be effectively resolved through the multiple protection mechanisms of the elastic support column 5, the multi-layer buffer assembly 6, and the anti-collision protrusion 15. The combination of the intelligent adjustment mechanism 10 and the clamping assembly 11 further improves the dynamic adaptability of the device, ensuring the stability of the phone in the protective device. The design of the anti-collision protrusion 15 and the auxiliary support foot 16 provides additional safety for complex falling scenarios and daily use.

[0041] The above is only one preferred embodiment of the utility model, any modification, equivalent replacement or improvement within the spirit and principles of the utility model should be included in the protection scope of the utility model. The contents not described in detail in the specification belong to the existing technology known to those skilled in the art, the model parameters of various electrical components are not specifically limited, and conventional equipment can be used to realize it. The electrical control elements not mentioned in the technical solution belong to the existing technology, so they are not shown in the figure, and will not be described here.
