Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mobile device accessories, in particular, to a bionic holding handle specially used for improving the holding experience of a mobile device in multi-finger operation, especially four-finger, five-finger, six-finger operation. BACKGROUND

[0002] With the rapid development of mobile game competitiveness, in order to pursue the ultimate operation efficiency and response speed, high-end players have generally adopted complex operation modes of four-finger, five-finger, six-finger or even more fingers. In such multi-finger operation scenarios, the player's palm presents a special stretching posture, and the weight of the whole machine of the mobile phone and the weight of the additional cooling accessories to ensure high-performance operation are mainly borne in the palm area of the player, resulting in a significant increase in pressure in this area, which easily causes rapid fatigue and soreness of the palm muscles, and long-term operation is more likely to cause cumulative muscle and skeletal disease risks such as metacarpophalangeal joint strain and carpal tunnel syndrome.

[0003] The current market products related to mobile game holding have a series of defects that cannot meet the needs of high-end competition, mainly embodied in the following two categories:

[0004] The first is an integrated stretching handle or grip, and the rigid connected structure inevitably blocks the back area of the mobile phone, so that the current mainstream external heat sink cannot be installed, which seriously restricts the heat dissipation performance and continuous performance output of the mobile phone under high load games. The analog joystick configured by it generally has a physical dead zone, and these defects together cause a perceptible lag in the transmission and execution of operation instructions, which is particularly deadly in high-speed and precise competition scenarios.

[0005] The second is a simple split grip, although it adopts a split structure to avoid complete blocking of the center of the back of the mobile phone, but its design is often simple, without scientific ergonomic modeling based on the skeletal structure and muscle distribution of the human hand in multi-finger operation state, and can only provide basic holding function, and cannot effectively support and disperse the pressure on the metacarpal and phalangeal structures according to the principles of biomechanics, and the effect of improving the operation comfort is limited.

[0006] Patent search found that the prior art has a scheme to try to solve the interface interference and heat dissipation problem. For example, the Chinese utility model patent CN207166583U discloses an "integrated mobile phone game handle", which transfers the mobile phone interface function to the position not blocking the hand through the built-in audio adapter module, and tries to integrate the heat dissipation module in the shell. However, this scheme has fundamental limitations: first, its integrated structure must block the center area of the back of the mobile phone, and users cannot select and install a higher-performance external active cooler according to the actual heat dissipation needs, the flexibility and ultimate performance of the heat dissipation scheme are limited, and the integrated structure usually has a large weight, which further increases the burden of holding; second, its holding part still adopts a general shape design, which is not specifically optimized for the skeletal support and pressure distribution of the palm in the stretched state when operating with four fingers or more, and the design process lacks analysis and construction of biomechanical data of human finger bones, metacarpal shape and muscle group stress model, so it cannot solve the core pain point of concentrated palm pressure when operating with multiple fingers.

[0007] Further search found that Chinese patent CN209900690U provides a mobile phone game handle with a back multi-key layout, which sets an ergonomic curved surface on the holding part and arranges parallel function keys on the back to support multi-finger operation. However, this design has poor charging compatibility, poor holding feel due to non-true optimization based on human structure, and lack of heat dissipation structure, etc. Another Chinese patent CN223208957U discloses a wired integrated handle with hidden USB connector, which realizes the extension and hiding of USB connector through innovative slide rail structure, solving the problem of damage caused by exposed interface. However, this wired scheme still has the problems of analog rocker dead zone affecting operation accuracy, blocked mobile phone heat dissipation path, tediousness of double adjustment of game virtual key position and handle physical key position, and frame drop caused by insufficient program debugging.

[0008] The above patents represent two technical directions of multi-finger operation and wired connection, but neither of them can systematically and cooperatively solve the fusion problem of key requirements such as non-delay operation, efficient heat dissipation compatibility, and deep scientific ergonomic comfort.

[0009] It needs to be particularly analyzed in depth that the existing mature traditional game handle (such as XBOX handle and the like) has excellent ergonomic design, but its bionics profile is mainly optimized for the "natural holding state" of the palm heart natural wrapping, mainly operated by the thumb and the index finger. This classic design paradigm cannot be directly applied to the multi-finger (four fingers and above) operation scene on the mobile phone. In multi-finger operation, the user's palm is in the "stretching operation state" for stable support of the weight of the mobile phone and allows multiple fingers to click flexibly above the screen. Its skeletal support points, moment distribution and pressure relief needs are essentially different from the "natural holding state". The wrapped profile of the traditional handle cannot provide effective and comfortable support in this stretching state, but may compress the key muscle and nerve area of the palm and limit the freedom of movement of the finger joints.

[0010] In summary, although the prior art has improved in interface avoidance, basic holding and the like, there is still a clear technical gap in how to specially target the "stretching operation state" required for high-end multi-finger operation, provide a scientific and comfortable holding experience based on biomechanical modeling, and at the same time realize lossless compatibility with high-efficiency external cooling equipment and peripheral compatibility. This is the core technical problem that the present application aims to overcome. SUMMARY

[0011] The purpose of the present application is to overcome the shortcomings of the prior art and provide a bionic holding handle specially designed for four-finger and above operation posture. Its bionics profile is specially designed for "multi-finger stretching operation state", aiming to fundamentally solve the pressure dispersion problem in this specific scene through scientific ergonomic design, and improve the comfort of long-time gaming; and at the same time, through the split structure, the compatibility problem with the external cooler is solved.

[0012] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0013] The application discloses a mobile device bionic holding handle for multi-finger operation, which is characterized in that the holding handle is particularly suitable for a four-finger or more operation holding posture, and comprises at least one holding body (1), wherein a holding surface of the holding body (1) is configured with a bionics profile. The bionics profile refers to a surface form generated by parameterized modeling based on a skeletal structure and a muscle stress model of a human hand in a four-finger or more operation stretched state, and is used for guiding finger stretching and dispersing stress. The bionics profile comprises at least one recess structure (11) and a raised structure (12). The recess structure (11) is configured to accommodate and guide at least one finger of a user in a stretched state in the multi-finger operation posture; and the raised structure (12) is arranged at a lower part of the holding body (1) and is configured to be supported on a metacarpal region of a palm of the user. A top of the raised structure (12) is inclined to a central axis of the mobile device by an angle, and the angle ranges from 0° to 70°, preferably 35°. The inclined design is used to adjust a posture of the palm and the wrist, so that a gravity component of the mobile device can be more effectively transmitted vertically to a wrist and forearm skeletal load through phalanges, and continuous force exertion of the fingers is avoided, thereby improving comfort.

[0014] Further preferably, the number of the recess structures (11) is three, and the forms and arrangements of the recess structures (11) are modeled and optimized based on natural forms and size data of phalanges and metacarpals of a human hand, and are respectively used for guiding middle fingers, ring fingers and little fingers of the user to be in a natural stretched state. In a six-finger operation posture, usually two of the recess structures (11) are used to accommodate and guide the ring fingers and the little fingers.

[0015] Further preferably, the holding handle is a split structure, and comprises two independent holding bodies (1) which are symmetrically arranged on the left and right sides, and each of the holding bodies (1) is detachably fixed to the mobile device through a connecting mechanism (2). The connecting mechanism (2) is one of an elastic clamping mechanism, a magnetic attraction mechanism, a screw mechanism or a buckle mechanism, and functions to firmly fix the holding handle to the mobile device on the left and right sides.

[0016] Still further preferably, the holding body (1) is formed by a handle upper part (15) and a handle lower part (16) which are connected through clamping or screw fixing or the like. A hollow region (13) is formed between the handle upper part (15) and the handle lower part (16). The structure design mainly aims at reducing the overall weight of the holding body (1). Secondly, the split structure formed on the left and right sides of the mobile device ensures that a central area of a back of the mobile device is completely exposed, thereby realizing perfect compatibility with various types of external semiconductor heat sinks.

[0017] Further preferably, the inner side of the holding body (1) is further provided with an adapter module mounting position for accommodating a wired adapter module (3), which is configured to extend the original physical interface function of the mobile device to the back surface of the holding body (1). In a preferred embodiment, the adapter module mounting position is combined with a wired earphone slot (14) for wire arrangement. The holding body (1) is further provided with a plug accommodating bin (31) for accommodating the plug of the wired adapter module (3) or the receiver of an external device such as a 2.4G wireless earphone.

[0018] In a preferred embodiment, the holding body (1) is made of a polymer material by additive manufacturing or injection molding process, and is internally provided with a polyhedral grid-like support structure, which is mainly designed for weight reduction, and the weight of a single holding body (1) is not more than 50 grams.

[0019] Compared with the prior art, the beneficial effects of the present application include:

[0020] Revolutionary comfort improvement: through the bionics contour design specially for multi-finger stretching state, the pressure is scientifically dispersed to the finger bone and metacarpal area with stronger bearing capacity. At the same time, the optimized material and internal grid-like support structure greatly reduce the self-weight while ensuring the strength. Through physical model testing, in the vertical holding state (which is the most mainstream and most ergonomic biological curve game posture), the contact area is greatly increased when using the present handle compared with directly holding the naked machine. In calculation, the load of the naked machine state is the weight of the test mobile phone itself (with protective shell, total weight 259 g, i.e. 2.539 N); the load of the handle state is the total weight of the test mobile phone and two holding handles (359 g, i.e. 3.519 N). The specific data comparison is as follows:

[0021] Six-finger operation (vertical): the contact area of the naked machine is 134 mm², and the average pressure is about 18.94 kPa; after using the handle, the contact area increases to 1980 mm², and the average pressure decreases to about 1.78 kPa. The pressure reduction amplitude is 90.6%.

[0022] Four-finger operation (vertical): the contact area of the naked machine is 134 mm², and the average pressure is about 18.94 kPa; after using the handle, the contact area increases to 3100 mm², and the average pressure decreases to about 1.14 kPa. The pressure reduction amplitude is 94.0%.

[0023] Four-finger operation (horizontal): bare-handed contact area 1110 mm², average pressure about 2.29 kPa; after using the handle, the contact area increases to 4764 mm², and the average pressure decreases to about 0.74 kPa. The pressure reduction rate is 67.7%. The present application can effectively reduce the average pressure during operation. It should be particularly noted that when the external radiator is attached, the total load is further increased, and the weight ratio of the handle is further reduced, so that the pressure reduction rate is more significant, further improving the comfort when using a heavy radiator. In addition, horizontal operation cannot be performed in six-finger state.

[0024] Perfect heat dissipation compatibility: the split design ensures perfect compatibility with various clamping or magnetically attracted external radiators. Users can choose high-efficiency cooling solutions as needed to ensure continuous operation of high-performance mobile phones.

[0025] Enhanced user-friendliness: through the optional integrated adapter module and plug receptacle (31), "cable behind" and receiver hiding are achieved, and users can game while charging / screen mirroring live without being disturbed by cables.

[0026] It should be particularly noted that the bionics profile of the present application is fundamentally different from conventional gamepads (such as XBOX gamepad) in that it is designed for the stretched state of the palm when supporting the weight of the mobile phone, and the multiple fingers need to operate on the screen above the phone. This is fundamentally different from the holding state of conventional gamepads, which wrap the palm around the gamepad and mainly use the thumb and index finger to operate. The profile of the present application guides the fingers to stretch forward and distribute pressure, rather than wrapping the palm into the gamepad. BRIEF DESCRIPTION OF DRAWINGS

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. All other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of the present application.

[0037] Please refer to Figures 1-8 , the present application provides a technical solution: in the preferred embodiment, the holding handle is split, including two left and right symmetrical holding handle bodies (1), two left and right symmetrical connecting mechanisms (2) and a wired adapter module (3) located on the right side, the holding handle body (1) is made of additive manufacturing or injection molding process. Its internal design is a polyhedral grid support structure, the design purpose is to reduce weight, and the weight of a single holding handle body (1) is controlled within 50 grams.

[0038] The outer surface of the holding handle body (1) is designed with a bionics profile. Specifically, the profile includes three arc-shaped recess structures (11), the shape, depth and spacing of these grooves are based on anthropometric data parameterized modeling and optimization, respectively for accommodating and guiding the middle finger, ring finger and little finger. When operating with six fingers, usually two of them are used to place the ring finger and little finger. In the lower part of the holding handle body, a metacarpal support protrusion (12) is provided, which is accurately corresponded to the connection area between the proximal phalanx and metacarpal of the human hand, and the protrusion is inclined to the center of the mobile phone by 35°.

[0039] See Figure 5 and Figure 6 , the holding handle body (1) is composed of the handle upper part (15) and the handle lower part (16) joined by screws, and a hollow area (13) is formed between them. The hollow area (13) is mainly used to avoid the camera module protruding on the back of the mobile phone during installation. The split structure exposes the center of the back of the mobile phone completely, which is compatible with external heat sinks.

[0040] The connecting mechanism (2) in this embodiment is an elastic clamping mechanism, which serves to firmly clamp the holding handle body (1) on both sides of the mobile device. The user can purchase a matching wired adapter module (3) as needed, which can be placed in the adapter module mounting position, which is combined with the wired earphone slot (14) in a preferred example. The holding body (1) is also provided with a plug storage bin (31) for storing the plug of the adapter module or a wireless receiver. After installation, the output interface of the adapter module is exposed from the back of the handle, realizing "cable behind".

[0041] Referring to Figure 7 With Figure 8 , the recess structure (11) is optimized in form and can simultaneously accommodate single four-finger holding and six-finger holding. Figure 7 The placement of the fingers when four-finger holding is shown, Figure 8 The little finger is also supported when six-finger holding is shown. Both holding methods disperse the gravity through the inclined raised structure (12) to the forearm skeleton, greatly improving comfort.

[0042] The above-mentioned embodiments only express the implementation of the present application, but cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
