Description

Technical Field

[0001] This utility model relates to the field of electronic product application technology, and in particular to a rotating structure and mobile phone holder with anti-motor jamming. Background Technology

[0002] With the widespread use of smartphones, their frequency of use in people's daily lives and work is increasing, and their functions are becoming more and more diverse. As an auxiliary tool, phone stands facilitate users in various scenarios, enabling them to watch videos, make video calls, browse the web, and so on, leading to a growing market demand. However, existing phone stands have many problems in their use, limiting the improvement of the user experience.

[0003] The limitations of manual adjustment: Most traditional phone holders rely on manual angle adjustment, requiring users to manually toggle or rotate the holder to achieve the desired angle. This method is not only inconvenient, especially when users' hands are busy (such as cooking or driving), making it difficult to quickly adjust the holder angle, but also lacks precision, making it difficult to achieve fine angle adjustments and failing to meet the diverse needs of users in different usage scenarios.

[0004] While electrically adjustable phone holders have emerged in recent years, offering improved convenience through built-in motors for automatic adjustment, they also present some drawbacks in practical use. For example, excessive resistance or jamming during motor rotation can easily lead to motor burnout. This is because a jammed motor continuously outputs a large current, which can damage internal components such as coils and brushes, affecting the phone holder's lifespan and reliability. Furthermore, the structural design of existing electric phone holders is not optimal, with the connection between the motor and the holder prone to loosening or wear, further reducing product stability and durability.

[0005] Limited functionality: Besides the issue of adjustment methods, existing phone stands offer relatively basic features, failing to meet diverse user needs. With technological advancements, mobile phones are no longer just for communication and entertainment; they also integrate with smart home devices and wearable devices. For example, many users desire the ability to conveniently wirelessly charge their phones or charge smartwatches while using a phone stand. However, most current phone stands only provide basic support, lacking these additional functions, thus limiting their application in modern life.

[0006] In terms of appearance and practicality, existing phone stands are relatively simple in design, lacking aesthetics and personalization. In modern home and office environments, consumers not only value the practicality of products but also have high demands for their appearance. Furthermore, the internal wiring design of existing phone stands is unreasonable; exposed wires not only affect aesthetics but may also lead to wire wear, short circuits, and other safety hazards.

[0007] In conclusion, existing phone stands have certain shortcomings in terms of adjustment methods, structural design, functional versatility, and aesthetic appeal, failing to meet modern consumers' demands for high-quality, multifunctional, and aesthetically pleasing phone stands. Therefore, it is necessary to design a new type of phone stand to address the problems of existing products, improve user experience, and meet the market's need for a high-performance phone stand. Summary of the Invention

[0008] In view of the above-mentioned defects, the purpose of this utility model is to solve the problems of existing mobile phone holders, such as difficulty in compatibility between manual and electric operation and the easy occurrence of jamming and high current burnout when the motor is rotating.

[0009] To address the above problems, this utility model specifically proposes a rotating structure with anti-motor jamming features. The base and support rod are connected via a first rotating shaft mechanism. This mechanism includes a rotating shaft positioned on the upper part of the base, with a motor mounting seat on the left side of the shaft. A DC motor is fixed within the motor mounting seat. A left rotating shaft seat and a right rotating shaft seat are respectively located on the upper side of the support rod. The left rotating shaft seat has a rotor mounting seat on its left opening and a threaded through-hole and a compression through-hole on its right side. A semi-circular anti-fooling opening is provided in the middle of the rotor section, which fits perfectly into the motor rod of the DC motor. The outer slope of the damping rotor is provided, and the compression through-hole of the compression damping component is also provided with a matching slope. The compression damping component is tightly fitted and fixed to the damping rotor. The compression damping component is secured to the left rotating shaft seat by damping fastening screws. The compression resistance of the compression damping component against the damping rotor can be adjusted by adjusting the damping fastening screws.

[0010] The rotating structure with anti-motor jamming feature is characterized in that, after the damping fastening screw is fixed, there is an adjustment redundancy space between the damping rotor and the left rotating shaft seat.

[0011] A mobile phone stand is characterized by comprising a faceplate, a support rod, and a base. The base and the support rod are connected by a first rotating shaft mechanism, and the support rod and the faceplate are connected by a second rotating shaft mechanism. The first rotating shaft mechanism and the second rotating shaft mechanism adopt a rotating structure based on the same principle, and the rotating structure has the aforementioned anti-motor jamming feature.

[0012] The mobile phone holder is characterized in that a first auxiliary rotating shaft stator mounting seat is provided on the right side of the first rotating shaft, the left end of the first auxiliary rotating shaft stator is snapped onto the first auxiliary rotating shaft stator mounting seat, the part of the first auxiliary rotating shaft stator extending out of the first auxiliary rotating shaft stator mounting seat is cylindrical, matches the through hole on the upper right rotating shaft seat, and extends into the upper right rotating shaft seat.

[0013] The mobile phone holder is characterized in that the upper right pivot seat is provided with a right pivot isolation pad, a touch-sensitive copper foil, and a CD-pattern decorative piece, the touch-sensitive copper foil being used to sense user touch operations.

[0014] The mobile phone holder is characterized in that a circular wireless charging pad mounting base is provided at the center of the face shell, and a circular wireless charging ring is set at the center of the circular wireless charging ring mounting base; it also has a rotating gear face cover, which is circular in shape and has an annular magnet groove on its inner side, with the magnet ring glued into the annular magnet groove; the face shell has an annular face cover groove, the inner side of the rotating gear face cover has a gear, and the annular face cover groove has a slingshot groove with a metal slingshot on it.

[0015] The mobile phone holder is characterized in that a charging cable guide hole is provided between the first rotating shaft and the circular wireless charging pad mounting base.

[0016] The mobile phone holder is characterized in that the right side of the support rod has a wire groove, and the electrical connection wire of the wireless charging coil passes through the charging cable guide hole, then through the first auxiliary rotating shaft stator, then along the wire groove, then through the second auxiliary rotating shaft stator, and then through the bottom wire hole set in the base to be electrically connected to the charging base connecting plate.

[0017] The mobile phone holder is characterized in that a Hall effect magnet or a voice sensor is also provided on the support rod.

[0018] The mobile phone stand is characterized by further including a watch charging assembly, which includes a watch face cover, a watch charging pad, and a watch back case. The watch back case has a mounting groove that matches the watch charging pad. The watch charging pad is placed on the mounting groove and covered by the watch face cover, which is snapped onto the watch back case by a buckle. The watch pivot is fitted with a watch pivot damping tube and then inserted into a side hole in the watch back case. The support rod has a watch charging mounting shaft hole, and both ends of the watch pivot extend into the watch charging mounting shaft hole.

[0019] The beneficial effects of the technical solution of this utility model are as follows:

[0020] 1. Effectively prevents motor jamming: By setting a damping rotor and a compression damping component, and adjusting the compression resistance through the damping fastening screws, the DC motor rotates after being powered on, driving the damping rotor to rotate. Normally, the compression damping component and damping rotor are slightly tightened, and the rotation of the damping rotor drives the entire support rod to automatically open and rotate. When it rotates to a specific angle, the support rod will stop rotating because the screws and the base's anti-fooling mechanism lock it in place. However, the motor will continue to rotate at this point. When the motor's rotational force exceeds the lateral compression damping force of the compression damping component and the damping rotor, the damping rotor and compression damping component will begin to spin.

[0021] 2. Compatible with both manual and electric modes: This structure cleverly incorporates a manual mode. When the motor is not operating, the user can manually adjust the angle of the support rod. The rotational motion of the support rod and base is converted into damped rotational motion by the damped rotor and the compression damping component, protecting the motor from damage and improving the flexibility of the phone holder.

[0022] 3. Versatile Functionality: In addition to basic phone support, the phone stand integrates wireless charging, touch sensing, and smartwatch charging. Users can conveniently charge their phones and watches while using the stand, enhancing the product's practicality and added value.

[0023] 4. Rational Structure and Easy to Use: The various components of the phone holder are rationally designed, tightly connected, and structurally stable. Furthermore, by incorporating different limit and adjustment mechanisms, users can easily adjust the angle of the phone holder according to their needs, making operation simple and convenient and enhancing the user experience.

[0024] 5. Aesthetically pleasing and practical: The phone stand features decorative designs such as CD-patterned decorative pieces and Bluetooth charging decorative pieces, enhancing the product's aesthetic appeal. Furthermore, the clever internal wiring design ensures that the wires are not exposed, making the product look cleaner and more attractive, meeting the dual demands of modern consumers for both aesthetics and practicality in electronic products.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Figure 1 This is a 3D view of the phone stand in its unfolded state; Figure 2 This is a 3D view of the phone stand in its closed state; Figure 3 This is an exploded view of an embodiment of a mobile phone stand. The mobile phone stand mainly includes a rotating gear cover 1, a wireless charging coil 2, a magnetic ring 3, a slingshot 4, a faceplate 5, a CD-pattern decorative piece 6, a damping fastening screw 7, a compression damping component 8, a damping rotor 9, a left pivot isolation pad 10, a DC motor 11, an auxiliary pivot stator 12, a right pivot isolation pad 13, a support rod 14, a watch face cover 15, a watch coil 16, a watch back case 17, a watch pivot damping tube 18, a watch pivot 19, a Hall effect sensor magnet 20, a support rod cable cover decorative piece 21, a base 22, a Bluetooth charging decorative piece 23, a base pivot auxiliary stator 24, a touch-sensitive copper foil 25, a charging dock connection plate 26, a lampshade 27, a motherboard fixing screw 28, a motherboard 29, a base bottom cover 30, a bottom cover screw 31, and an anti-slip pad 32.

[0035] Figure 6 This is a cross-sectional view of the phone stand in its unfolded state. Figure 7This is a partial exploded view of the first rotating shaft mechanism of the mobile phone holder. The base 22 of the mobile phone holder is connected to the support rod 14 through the first rotating shaft mechanism, and the support rod 14 is connected to the face shell 5 through the second rotating shaft mechanism. The first rotating shaft mechanism and the second rotating shaft mechanism adopt the same principle of rotation structure. The first rotating shaft mechanism includes a rotating shaft mounted on the upper part of the base 22. A motor mounting seat is provided on the left side of the rotating shaft, and a DC motor 11 is fixed in the motor mounting seat. A left rotating shaft seat and a right rotating shaft seat are respectively provided on the upper side of the support rod. A rotor mounting seat is provided on the left side of the left rotating shaft seat, and a threaded through hole and a pressing through hole are provided on the right side. A semi-circular anti-fooling opening is provided in the middle of the rotor part, which fits perfectly into the motor rod of the DC motor. The outer slope of the damping rotor 9 is provided, and the pressing through hole of the pressing damping component 8 is also provided with a matching slope 93. A step 92 is provided on the waist of the damping rotor 9, which abuts against the bottom surface. The pressing damping component is pressed and tightly fixed on the damping rotor 9. The pressing damping component is fastened to the left rotating shaft seat by the damping fastening screw. The pressing resistance of the pressing damping component 8 pressing the damping rotor 9 can be adjusted by adjusting the damping fastening screw 7. In order to achieve adjustable space, after the damping fastening screw is fixed, an adjustment redundancy space 91 is provided between the damping rotor 9 and the left rotating shaft seat.

[0036] The damping fastening screw extends out of the threaded through hole. The rotor mounting base of the base and faceplate has a rotating track recess with a foolproof locking mechanism. When the support rod rotates to a specific angle under the drive of the motor, the protruding part of the damping fastening screw locks into the foolproof locking mechanism of the rotating track recess, preventing the support rod from opening further. Tightening the screw compresses the side slopes of the damping element 8 and the damping rotor 9, generating damping force. Adjusting the tightness of the screw adjusts the rotational damping force. When the DC motor is powered on, it rotates, driving the damping rotor 8 to rotate. Normally, the damping element 8 and damping rotor 9 are slightly compressed, so the rotation of the damping rotor drives the rotation of the damping rotor 8, thereby automatically opening and rotating the entire support rod. When rotated to a specific angle, the support rod stops rotating due to the screws locking into the base's anti-fooling mechanism. However, the motor continues to rotate. At this point, the motor's rotational force exceeds the lateral compression damping force of the damping element 8 and the damping rotor 9, causing them to spin. This prevents the motor from burning out due to excessive current caused by a jammed motor. The structure also cleverly incorporates a manual mode. When the motor is not operating, manually opening the mechanism converts the rotation of the support rod and base into the damped rotation of the damping rotor 8 and the damping element 9, preventing damage to the motor's reduction gears from forced rotation.

[0037] Figure 5This is an exploded view of the phone charging section of the base, including a charging dock connecting plate 26, a lampshade 27, a motherboard fixing screw 28, a motherboard 29, a base bottom cover 30, a bottom cover screw 31, and an anti-slip pad 32. A first auxiliary shaft stator mounting seat is located on the right side of the first rotating shaft. The left end of the first auxiliary shaft stator is snapped onto the first auxiliary shaft stator mounting seat. The portion of the first auxiliary shaft stator extending out of the first auxiliary shaft stator mounting seat is cylindrical, matching the through hole on the upper right shaft seat, and extending into the upper right shaft seat. The upper right shaft seat is equipped with a right shaft isolation pad, touch-sensitive copper foil, and a CD-pattern decorative piece. The touch-sensitive copper foil is used to sense user touch operations.

[0038] Figure 4 This is an exploded diagram of the phone's charging section, including a rotating gear cover 1, a wireless charging coil 2, a magnetic ring 3, a slingshot 4, and the phone's casing 5. The casing has a circular wireless charging pad mounting base at its center, with the circular wireless charging coil positioned at the center of the mounting base. It also features a rotating gear cover, which is circular in shape and has an annular magnetic groove 52 on its inner side, into which the magnetic ring is glued. The casing has an annular cover groove, and the rotating gear cover has a gear on its inner side. A slingshot groove is located on the annular cover groove, and a metal slingshot 51 is mounted on it. The metal slingshot is fixed within the slingshot groove on the casing. When the cover rotates, it engages with the metal slingshot, producing a clicking sound when struck, indicating decompression.

[0039] Internal wiring is also an innovation of this invention, ensuring that the wiring is not exposed. A charging wiring guide hole 53 is provided between the first rotating shaft and the circular wireless charging pad mounting base. The right side of the support rod has a wire groove. The electrical connection wire of the wireless charging coil passes through the charging wiring guide hole, then through the first auxiliary rotating shaft stator, then along the wire groove, then through the second auxiliary rotating shaft stator, and finally through the bottom wire hole provided in the base to electrically connect with the charging base connecting plate.

[0040] Figure 8 This is a diagram of the watch charging components. To further expand the functionality of the phone holder, a watch charging function has been added, along with a watch charging assembly. The watch charging assembly includes a watch face cover, a watch charging pad, and a watch back case. The watch back case has a mounting groove that matches the watch charging pad. The watch charging pad is positioned in the mounting groove, and the watch face cover is placed on top of it, secured to the watch back case with clips. The watch pivot is fitted with a watch pivot damping tube and then inserted into a side hole in the watch back case. The support rod has a watch charging mounting shaft hole, into which both ends of the watch pivot extend. Installation: The watch coil 16 is threaded from the inside to the outside through the side hole of the watch back case 15. Then, the adhesive backing of the watch coil 16 is peeled off, and it is aligned with the positioning groove in the bottom hole of the watch back case 15 and attached. Finally, the watch face cover 15 is replaced and secured with clips. The watch pivot damping tube 18 is fitted into the side hole of the watch back case.

[0041] This phone holder automatically rotates to a Z-shape after being powered on, with the opening angle achieved through different limit switches. It can also be equipped with a voice recognition module to receive user voice commands, allowing for control of opening / closing or adjusting the opening angle based on these commands. Opening / closing can also be initiated with a simple touch.
