Description

Technical Field

[0001] This application relates to the technical field of flip structures, and more particularly to a flip block structure and an electronic device. Background Technology

[0002] In the lifting mechanism of electronic equipment, the tilting block is the core functional component for realizing the adjustment of the mechanism angle and the reversal of the transmission. Its structural rationality, manufacturing feasibility and cost control level directly affect the overall performance and market competitiveness of the lifting mechanism.

[0003] Currently, the industry primarily employs powder metallurgy or full CNC (computer numerical control) machining of aluminum alloys for manufacturing such tilting blocks. While powder metallurgy can achieve one-piece molding of certain complex structures, it presents challenges for tilting blocks with irregular cavities, intersecting channels, or thin-walled support structures. These challenges include difficulties in mold development and the potential for voids or dimensional deviations after molding, requiring additional finishing processes. While full CNC machining of aluminum alloys ensures high-precision dimensions and a smooth surface, it requires multi-station, multi-tool cutting for complex internal structures, resulting in long processing cycles, low material utilization, and the need for post-machining surface treatments such as anodizing and passivation to meet rust prevention and wear resistance requirements. These process characteristics lead to significantly higher processing and surface treatment costs for tilting blocks, hindering cost reduction through large-scale production of lifting mechanisms.

[0004] To address the issue of excessive costs, existing solutions attempt to manufacture the flip block using all-plastic materials, leveraging the mass production advantages of plastic injection molding to simplify the processing flow and reduce material costs. However, during the injection molding process, the fluidity and cooling shrinkage characteristics of plastic materials limit the process. To avoid defects such as material shortages, shrinkage marks, and cracking after molding, the bottom of the flip block is often too thick, leading to an increase in the overall thickness of the flip block. This, in turn, increases the overall thickness of the lifting mechanism of the electronic device equipped with the flip block, making it unsuitable for the design trend of thinner and lighter electronic devices. Utility Model Content

[0005] The purpose of this application is to provide a flip block structure and an electronic device to solve the technical problems existing in the prior art.

[0006] To achieve the above objectives, this application adopts the following technical solution: On one hand, a flip block structure is provided, including: an injection molded part and a metal part. The injection molded part has a hollow interior, a boss is provided on the inner side of the bottom of the injection molded part, and an assembly groove is provided on the bottom side of the boss. The assembly groove can accommodate a connecting part, and the metal part can be fixed to the bottom of the injection molded part through the connecting part.

[0007] Furthermore, the assembly groove is a dispensing groove, which can be filled with an adhesive liquid, and the metal part can be fixed to the bottom of the injection molded part by the adhesive liquid; the joint is the cured adhesive liquid.

[0008] Furthermore, the assembly groove has a protrusion in the middle, and the two sides of the protrusion form an overflow groove between the groove wall of the assembly groove.

[0009] Furthermore, the height of the protrusion is h1, and the depth of the assembly groove is h2, where h1 ≤ h2.

[0010] Furthermore, the thickness of the metal part is 0.2mm-0.3mm.

[0011] Furthermore, the metal part is positioned and connected to the injection molded part through a positioning structure. The positioning structure includes a positioning part disposed on one of the metal part or the injection molded part, and a positioning hole disposed on the other of the two parts. The positioning part and the positioning hole cooperate to position the metal part.

[0012] Furthermore, the injection molded part can be rotatably mounted on the housing, and the injection molded part can switch between a retracted state and an extended state. The injection molded part includes a first limiting part and a second limiting part. The first limiting part can engage with the inner wall of the housing when the injection molded part is switched to the extended state, and the second limiting part can engage with the inner wall of the housing when the injection molded part is switched to the retracted state.

[0013] Furthermore, the injection molded part also includes a third limiting part, which is arranged at intervals with the first limiting part along the rotation axis of the injection molded part. When the injection molded part is in the extended state, the first limiting part abuts against the inner wall of the housing for limiting, and there is a gap between the third limiting part and the inner wall of the housing, so that when the injection molded part rotates more than the rotation angle of the extended state, the third limiting part can abut against the inner wall of the housing for limiting.

[0014] Furthermore, the injection molded part includes a main body, and the first limiting part, the second limiting part and the third limiting part are symmetrically formed on both sides of the main body.

[0015] Furthermore, the metal part is a steel sheet.

[0016] On the other hand, an electronic device is also provided, including: a housing and the aforementioned flip block structure, wherein the injection molded part is rotatably connected to the housing.

[0017] The beneficial effects of this application are as follows: the metal parts are fixed to the bottom of the injection molded parts through the joint in the assembly groove, replacing the thick plastic layer of the traditional all-plastic structure to bear the function of support and structural reinforcement. The injection molded parts do not need to retain a thick plastic layer to meet the strength requirements. They can be designed as thin structures and further thinned with internal hollowing, fundamentally solving the problem of thickening of the whole machine in the all-plastic solution. Moreover, thin injection molded parts are prone to insufficient strength and poor wear resistance. Metal parts, with their superior mechanical properties, can make up for the shortcomings of plastic materials in shear resistance, impact resistance, and wear resistance. After forming a stable connection with the injection molded part through the joint, the metal parts can directly bear the load during the transmission process of the lifting mechanism, avoiding deformation or cracking of thin plastic structures due to stress concentration. At the same time, the composite structure of metal parts and injection molded parts can improve the fatigue resistance of the flipping block under repeated reversing impacts, ensuring structural stability during long-term use.

[0021] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] like Figures 1-3 As shown, this embodiment provides a flip block structure, including: an injection molded part 1 and a metal part 2. The injection molded part 1 has a hollow interior. A boss 101 is provided on the inner side of the bottom of the injection molded part 1. An assembly groove 102 is provided on the bottom side of the boss 101. The assembly groove 102 can accommodate a connecting part. The metal part 2 can be fixed to the bottom of the injection molded part 1 through the connecting part.

[0025] Combination Figures 1 to 2 The injection molded part 1 is hollowed out, and a metal part 2 is fixed to the bottom of the injection molded part 1 to close the opening at the bottom of the injection molded part 1. The opening at the top of the injection molded part 1 is not closed. Figure 3 , Figure 4 The flip block structure has a groove formed by the inner wall of the injection molded part 1 and the top wall of the metal part 2, and the top of the injection molded part 1 has a top slot of the groove. This groove can be used to assemble camera modules or other electronic modules.

[0026] The assembly groove 102 is a dispensing groove, which can be filled with adhesive liquid, and the metal part 2 can be fixed to the bottom of the injection molded part 1 by the adhesive liquid; the joint is the cured adhesive liquid.

[0027] Based on the above solution, in terms of mechanical performance and transmission stability, the introduction of metal part 2 can specifically compensate for the performance shortcomings of the thin plastic structure. The shear strength, wear resistance, and fatigue resistance of metal part 2 are all superior to those of plastic. That is, by using metal part 2 as the bottom to replace the thick plastic base of the all-plastic structure, it can effectively withstand the load impact of the flipping block during transmission, reduce the failure risk of the thin injection molded part 1 due to insufficient strength, and extend the service life of the flipping block. At the same time, metal part 2 forms a stable connection with injection molded part 1 through the joint, and with the positioning function of boss 101, it can ensure that there is no relative displacement between the two during long-term use, ensuring that the flipping block is not easily deformed or cracked during angle adjustment and transmission reversal, and providing reliable support for the overall transmission stability of the lifting mechanism.

[0028] Regarding thickness optimization, addressing the issue of increased overall thickness due to the need for a thicker plastic layer in all-plastic solutions caused by melt flow and cooling shrinkage characteristics, this structure constructs a support system using a boss 101 on the inner side of the bottom of the injection molded part 1 and an assembly groove 102 on the bottom side of the boss 101. The assembly groove 102 accommodates the joint, firmly fixing the metal part 2 to the bottom of the injection molded part 1, allowing the metal part 2 to directly replace the load-bearing and structural reinforcement functions of the thick plastic layer in traditional all-plastic structures. As a result, the bottom body of the injection molded part 1 does not need to rely on a thick plastic layer to ensure strength, and can be designed to be thinner. The internal hollow design of the injection molded part 1 reduces unnecessary plastic usage, significantly reducing the overall thickness of the flipping block from both the bottom plastic reduction and internal hollow design, effectively adapting to the trend of thinner and lighter design of electronic device lifting mechanisms.

[0029] In terms of cost control, the structure uses injection molded part 1 as the main body, giving full play to the advantages of plastic injection molding technology. It can form an internal hollow structure in one piece, without the difficulties of mold development and complicated subsequent finishing processes faced by powder metallurgy. It also eliminates the need for multi-station cutting and surface treatment processes such as anodizing and passivation required for full CNC machining of aluminum alloy. At the same time, the cost of plastic materials is significantly lower than that of metal powder and aluminum alloy, avoiding the high cost of traditional metal-based processes. This meets the cost control requirements for large-scale production of lifting mechanisms and continues and strengthens the low-cost characteristics of the all-plastic solution.

[0030] Furthermore, a protrusion 103 is provided in the middle of the assembly groove 102, and an overflow groove 104 is formed between the two sides of the protrusion 103 and the groove wall of the assembly groove 102. The protrusion 103 serves as the core main structure within the assembly groove 102, with its top surface directly attached to the metal part 2, forming the main support carrier for the connection between the metal part 2 and the injection molded part 1. It provides a stable contact reference for the metal part 2, ensuring the positioning accuracy of the metal part 2 during assembly, and can directly bear the lateral shear force, vertical pressure, and other loads between the metal part 2 and the injection molded part 1, forming the main load-bearing layer for the connection. At the same time, the protrusion 103 can guide the adhesive liquid to be evenly distributed on both sides, so that the adhesive layer fills the space between the protrusion 103 and the groove wall of the assembly groove 102, forming a composite connection structure, thus avoiding the problem of insufficient load-bearing capacity caused by the metal part 2 relying solely on the adhesive layer for connection.

[0031] In the dispensing process, in order to ensure the reliability of adhesive adhesion, an appropriate amount of adhesive liquid needs to be injected. When the amount of glue used is slightly more than the baseline requirement, the overflow groove 104 can collect the excess glue through its groove space, preventing the glue from exceeding the range of the assembly groove 102. This avoids excessive glue overflow from contaminating the hollow channels of the injection molded part 1, the side walls of the boss 101, or solidifying into glue nodules on the non-adhesive surface of the metal part 2, thereby preventing assembly interference and structural functional failure caused by glue contamination.

[0032] Furthermore, the height of the protrusion 103 is h1, and the depth of the assembly groove 102 is h2, where h1 ≤ h2. When h1 ≤ h2, the top surface of the protrusion 103 does not exceed the groove opening plane of the assembly groove 102, or is flush with the groove opening. This avoids the metal part 2 not being able to fully contact the top surface of the protrusion 103 when it is attached due to the excessive height of the protrusion 103, thus preventing the formation of a contact gap. This ensures that the metal part 2 can fully contact the top surface of the protrusion 103 after assembly, constructing a stable load-bearing interface and providing a structural basis for the direct transmission of loads such as lateral shear force and vertical pressure, avoiding load transmission failure or stress concentration caused by gaps. The depth h2 of the assembly groove 102 determines the total adhesive space of the groove, while the height h1 of the protrusion 103 determines the space occupied by the protrusion 103 within the groove. h1≤h2 ensures sufficient adhesive volume within the assembly groove 102. This volume accommodates adhesive used for bonding, ensuring that the adhesive fully fills the gap between the protrusion 103 and the groove wall of the assembly groove 102 to form a composite connection. Furthermore, this volume, together with the overflow groove 104, collects excess adhesive, preventing overflow due to insufficient adhesive space in the assembly groove 102, further enhancing the anti-overflow effect, and preventing excessive compression of the adhesive due to limited space, which could affect the bonding strength of the cured adhesive layer.

[0033] Furthermore, if h1 > h2, the protrusion 103 will protrude beyond the opening of the assembly groove 102, causing interference between the metal part 2 and the protrusion 103 during assembly. This would prevent the metal part 2 from fitting in the designed position and could even cause structural damage to the protrusion 103 or the metal part 2. However, the size limitation of h1 ≤ h2 ensures that the protrusion 103 is completely contained within the assembly groove 102 without interfering with the assembly path of the metal part 2, thus improving assembly feasibility. At the same time, this dimensional relationship provides flexibility for the design optimization of the height of the protrusion 103 and the depth of the assembly groove 102. For example, h1 can be adjusted according to different load requirements, and h2 can be adjusted according to the amount of adhesive required, adapting to the structural design of different specifications of flipping blocks and enhancing the dimensional compatibility of the technical solution.

[0034] It is worth mentioning that the thickness of the metal part 2 is 0.2mm-0.3mm. As a reinforcing component at the bottom of the injection molded part 1, the thickness of the metal part 2 directly affects the overall thickness control effect of the flip block. The thickness range of 0.2mm-0.3mm can precisely match the goal of lightweight design. If the thickness is >0.3mm, the total thickness of the bottom of the flip block will increase, offsetting the thickness optimization benefits brought by the reduction of the plastic material in the injection molded part 1. If the thickness is <0.2mm, the in-plane rigidity and deformation resistance of the metal part 2 are insufficient, and it cannot replace the thick plastic layer of the all-plastic solution to achieve the support and wear resistance functions. This thickness range can ensure that the metal part 2 meets the reinforcement requirements under the premise of minimum thickness, and works in conjunction with the injection molded part 1 and the protrusion 103 structure to achieve the overall lightweight design of the flip block.

[0035] As an optional specific implementation plan, such as Figure 4 , Figure 5 As shown, the metal part 2 is positioned and connected to the injection molded part 1 through a positioning structure. The positioning structure includes a positioning part 201 disposed on either the metal part 2 or the injection molded part 1, and a positioning hole 109 disposed on the other. The positioning part 201 and the positioning hole 109 cooperate for positioning. The positioning part 201 and the positioning hole 109 are designed with a clearance fit or a transition fit. During assembly, the positioning part 201 can be embedded in the positioning hole 109 to form a rigid positioning constraint along the assembly plane. This provides a unique reference for the fit between the metal part 2 and the injection molded part 1, avoiding misalignment of the fit position of the metal part 2 due to human operation deviation or displacement of automated equipment during the assembly process.

[0036] One method is to use a nested molding process for fixing. During nested molding, the metal part 2 is positioned and fixed inside the mold through the protruding parts on both sides. After molding, the excess metal parts are removed. That is, the positioning part 201 needs to be removed from the outer surface of the injection molded part 1 after injection molding. Specifically, when the mold is closed, after the metal part 2 is placed into the cavity, its protruding parts on both sides are embedded in the preset limiting space of the mold. The mechanical limiting achieves the radial and axial bidirectional positioning of the metal part 2 in the mold, ensuring that the metal part 2 does not shift, deflect, or float during injection molding. This provides a positional reference for the precise bonding of the plastic melt and the metal part 2, solving the bonding deviation problem caused by the easy displacement of the metal part 2 in traditional nested molding.

[0037] After the mold is closed and the metal part 2 is positioned, the molten plastic is injected into the cavity through the preset flow channel. The molten plastic wraps the main body area of ​​the metal part 2, except for the protruding parts on both sides, forming an interface fusion structure between the plastic matrix and the metal body layer. On the one hand, the molten plastic fills the tiny gaps on the surface of the metal part 2 under high pressure, and after solidification, it forms a mechanical interlocking effect, realizing a tight bond between the plastic and the metal. On the other hand, during the die-casting process, the main body area of ​​the metal part 2 is precisely wrapped and positioned by the plastic, without the need for subsequent secondary assembly and adjustment. This directly constructs the core load-bearing and connecting structure of the flip block, which is different from the traditional post-assembly mode of fixing with glue and strengthens the overall structure.

[0038] After the die-cutting process, the protruding parts on both sides of the metal part 2 need to be removed by precision machining methods such as CNC milling and laser cutting to achieve positioning within the mold. This process ensures that the outer circumference dimensions of the flipping block meet the design tolerances and prevents the protruding parts from exceeding the assembly boundary of the flipping block, thus avoiding interference with other components of the lifting mechanism.

[0039] In some embodiments, such as Figure 6 , Figure 7 As shown, the injection molded part 1 can be rotatably mounted on the housing 3, and the injection molded part 1 can switch between a retracted state and an extended state. The injection molded part 1 includes a first limiting part 105 and a second limiting part 106. The first limiting part 105 can engage with the inner wall of the housing 3 when the injection molded part 1 is switched to the extended state, and the second limiting part 106 can engage with the inner wall of the housing 3 when the injection molded part 1 is switched to the retracted state. The injection molded part 1 is rotatably mounted on the housing 3 through a rotating shaft, hinge, or shaft hole engagement structure, constructing a motion system that can rotate around a fixed axis. This structure provides a mechanical basis for the injection molded part 1 to switch between the retracted state (fitting against the inner wall of the housing 3, occupying minimal space) and the extended state (expanding outward, realizing lifting / transmission functions), ensuring that the state switching process has a stable motion trajectory and avoiding structural interference caused by irregular displacement.

[0040] When the injection molded part 1 rotates around the rotation axis in the extension direction until it switches to the preset extension state, the first limiting part 105 on the injection molded part 1 forms a rigid contact with the preset limiting surface or limiting groove of the inner wall of the housing 3. The force-bearing surface of the first limiting part 105 abuts against the limiting surface of the inner wall of the housing 3, thereby restricting the injection molded part 1 from continuing to rotate in the extension direction through mechanical blocking. This locks the rotation angle of the injection molded part 1 within the preset range required by the function, ensuring that it maintains a stable posture in the extension state and providing a reliable position reference for the transmission and support functions of the lifting mechanism.

[0041] When the injection molded part 1 rotates around the rotation axis in the storage direction until it switches to the preset storage state, the second limiting part 106 on the injection molded part 1 forms a rigid fit with another set of preset limiting surfaces or limiting grooves on the inner wall of the housing 3. The second limiting part 106 abuts against the inner wall of the housing 3 through surface contact or line contact, preventing the injection molded part 1 from continuing to rotate in the storage direction. This avoids collisions or squeezing between the injection molded part 1 and the inner wall of the housing 3 due to excessive rotation, or interference with other components inside the housing 3. It ensures that the injection molded part 1 fits tightly against the housing 3 in the storage state and does not occupy extra space.

[0042] Meanwhile, the injection molded part 1 also includes a third limiting part 107. The third limiting part 107 and the first limiting part 105 are arranged at intervals along the rotation axis of the injection molded part 1. When the injection molded part 1 is in the extended state, the first limiting part 105 abuts against the inner wall of the housing 3 for limiting, and there is a gap between the third limiting part 107 and the inner wall of the housing 3, so that when the injection molded part 1 rotates more than the rotation angle of the extended state, the third limiting part 107 can abut against the inner wall of the housing 3 for limiting. The third limiting part 107 and the first limiting part 105 are arranged at intervals along the rotation axis of the injection molded part 1, forming two limiting action points distributed along the axis. The first limiting part 105 is a conventional extension limiting part. When the injection molded part 1 rotates to the designed extension state, it directly abuts against the inner wall of the housing 3, restricting the injection molded part 1 from continuing to rotate in the extension direction, ensuring the positional accuracy during normal use. The third limiting part 107 is an overtravel protection limiting part. When the injection molded part 1 is in the standard extension state, it maintains a preset gap with the inner wall of the housing 3. The size of this gap is designed to not interfere with the conventional limiting function of the first limiting part 105, thus avoiding the third limiting part 107 from being accidentally triggered in the normal extension state, and reserving buffer space for possible overtravel rotation of the injection molded part 1.

[0043] When the injection molded part 1 rotates in the extension direction at an angle greater than the standard extension angle due to unexpected factors (such as excessive user operation force or overload of the lifting mechanism transmission), the first limiting part 105 and the inner wall of the housing 3 cannot prevent the overtravel movement. At this time, as the injection molded part 1 continues to rotate, the gap between the third limiting part 107 and the inner wall of the housing 3 gradually decreases until the third limiting part 107 and the inner wall of the housing 3 are completely in contact. Through rigid contact, a secondary limiting constraint is formed, which forcibly terminates the overtravel rotation of the injection molded part 1, and avoids its own structural deformation, failure of connection with the housing 3, or impact damage to other transmission components of the lifting mechanism due to excessive rotation.

[0044] Generally, the injection molded part 1 includes a main body 108, with the first limiting part 105, the second limiting part 106, and the third limiting part 107 symmetrically formed on both sides of the main body 108. The limiting parts symmetrically formed on both sides of the main body 108 can simultaneously apply reaction forces from both sides of the rotation axis at the moment of contact. When the first limiting part 105 is in the extended state and contacts the main body 108, both first limiting parts 105 simultaneously contact the inner wall of the housing 3, avoiding unilateral force imbalance caused by unilateral contact. Similarly, when the second limiting part 106 is retracted and the third limiting part 107 is anti-over-rotation, both sides simultaneously contact the main body 1, ensuring that the reaction force on the injection molded part 1 is symmetrically distributed along the rotation axis, offsetting the deflection tendency caused by unilateral torque, and ensuring that the main body 108 always moves along the preset axis during rotation, without any risk of deviation or jamming.

[0045] Optionally, the metal part 2 is a steel sheet. The steel sheet possesses excellent in-plane rigidity, shear strength, and fatigue wear resistance, and can precisely match the functional positioning of the metal part 2 in replacing the thick plastic layer. In the assembled state, the steel sheet forms a stable connection with the bottom boss 101 of the injection molded part 1 through the adhesive liquid in the assembly groove 102 or the overlay process. When the flipping block is subjected to the lateral shear force of the lifting mechanism and repeated reversing impacts, the steel sheet can evenly transfer the load to the main body of the injection molded part 1, avoiding deformation or cracking of the thin plastic structure due to local stress concentration. At the same time, the high wear resistance of the steel sheet can resist the long-term friction between the metal part 2 and the injection molded part 1 and the shell 3, maintaining the connection stability and structural integrity.

[0046] On the other hand, an electronic device is also provided, including: a housing 3 and the aforementioned flip block structure, wherein the injection molded part 1 is rotatably connected to the housing 3.

[0047] Specifically, electronic devices can include tablets, smartwatches, smartphones, etc.
