Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary gripping devices for electronic mobile terminals. These electronic mobile terminals include smartphones, tablet computers, and other handheld electronic mobile terminals for other purposes. Because smartphones are a typical example of electronic mobile terminals, for simplicity and clarity, the term "mobile phone" will be used in this specification to describe electronic mobile terminals. Background Art

[0002] With the popularity of large-screen mobile phones, mobile phones have become an important part of people's lives and work. However, since mobile phones themselves do not have any auxiliary grip devices, people are prone to grip fatigue and accidental slipping when holding the phone for a long time. At the same time, due to the large screen of smartphones, the effective touch area is small when holding and operating the phone with one hand, and both hands are often required to operate the phone, which sometimes affects users from doing other important things at the same time. For example, when people are standing on a bus and using a mobile phone, they may sometimes leave the safety handrail due to operating the phone with both hands, which may cause accidents due to body instability when the vehicle starts, stops, or turns.

[0003] There are three main types of existing mobile phone auxiliary holding devices and technologies.

[0004] The first category is the mobile phone ring buckle. The mobile phone ring buckle is attached to the back of the mobile phone and can be worn on a single finger when holding the mobile phone. It can improve the problem of small touch area and easy slipping when holding the phone with one hand, and provides some mobile phone holder functions, such as Figure 1 However, since the finger ring still requires other fingers to hold the phone for stability, the flexibility and range of motion of the fingers are limited. Although the effective touch area when holding and operating the phone with one hand is larger than that of holding with a bare hand, it still cannot cover the entire screen. In addition, wearing the finger ring for a long time will cause obvious pressure and discomfort on the fingers, which can easily cause injury when subjected to strong external forces.

[0005] The second type is a mobile phone auxiliary holding device with a non-elastic strap structure. The non-elastic strap is installed on the base on the back of the mobile phone. One end is fixed and the other end can move along the slide in the base, so that the strap forms an arched space in which the user's fingers can wear and move up and down, such as Figure 2 This type of device offers good anti-slip performance and enables full-screen touch operation when holding the phone in one hand. However, due to the lack of self-tightening capability of the non-elastic strap, the grip is not snug enough, requiring careful grip in some scenarios. Furthermore, this type of device is typically mounted off-center on the back of the phone, making it uncomfortable when used alternately with either hand and unsuitable for phone stand functionality.

[0006] The third category is a mobile phone auxiliary holding device with an elastic strap structure. The elastic strap is fixed to both ends of the base on the back of the mobile phone. The user's fingers can wear it and move up and down, enabling full-screen touch operation when holding the mobile phone with one hand, such as Figure 3 As shown. Because elastic straps provide a certain degree of self-tightening force, they offer a comfortable grip and excellent anti-slip performance without requiring a careful grip. However, elastic straps will inevitably experience a loss of elasticity and permanent stretching over time. Furthermore, because elastic straps are typically made of woven fibers, they easily absorb sweat, dust, and other contaminants, causing them to become increasingly dirty over time.

[0007] Because the auxiliary grip device of the strap-type mobile phone is attached to the back of the mobile phone, for considerations of aesthetics and portability, the auxiliary grip device is required to have a relatively thin thickness, and it is usually difficult to adopt a conventional detachable design. Therefore, in traditional products, the strap can usually only be installed on the base on the back of the mobile phone by gluing, riveting or screws (including screws); and although the gluing and riveting methods are relatively simple in structure and process, the elastic strap cannot be removed, and the elastic strap cannot be effectively cleaned, adjusted in tightness or replaced for a long time; and the screw fixing method requires the use of a screwdriver tool to complete the assembly and disassembly process, and maintenance operations cannot be performed anytime and anywhere, which will affect the user experience and popular application of such products. Utility Model Content

[0008] This utility model aims to provide a mobile phone auxiliary grip device with an elastic strap that can be repeatedly attached, removed, and maintained, thereby comprehensively resolving maintenance and usage issues encountered when using a mobile phone, such as fatigue, slippage, small touchscreen area when held with one hand, loose elastic straps, and difficulty cleaning, removing, and replacing them. Furthermore, this utility model can be well integrated with existing rectangular mobile phone holder technology, thereby comprehensively improving the comfort, convenience, and safety of mobile phone users.

[0009] The present invention proposes two removable elastic shoulder strap connection structures, namely, elastic shoulder strap connection structure example 1 and elastic shoulder strap connection structure example 2. Both elastic shoulder strap connection structures have the advantages of simple structure and can be quickly assembled and disassembled by hand. At the same time, each has its own characteristics. They can be used alone or in combination with each other, and can also be combined with other traditional elastic shoulder strap connection structures.

[0010] Elastic strap connection structure example 1 and elastic strap connection structure example 2 both include two basic components: a base and an elastic strap.

[0011] The base is generally in the shape of a rectangular plate and is attached to the back of the phone. It can also be integrated with the phone's back cover or protective case.

[0012] Example 1 of an elastic strap connection structure includes a base 1, an elastic strap 2, a slot 3, and a bolt 4. The base 1 is attached to the back of an electronic mobile terminal. The slot 3 is a transverse slot with a narrow opening formed on the base 1. The bolt 4 is formed at the end of the elastic strap 2 and is assembled into the slot 3 of the base 1 from the side using an interference fit, allowing for repeated assembly and disassembly. Because the bolt assembly direction is perpendicular to the working force direction of the elastic strap, only a small interference fit between the bolt and the slot is required to form a reliable assembly connection between the elastic strap and the base. This small interference fit also makes assembly and disassembly easier.

[0013] Example 2 of an elastic strap connection structure comprises a base 1, an elastic strap 2, a flat cavity 5, and a plug 6. The base 1 is attached to the back of the electronic mobile terminal; the flat cavity 5 is formed at one end of the base 1. The elastic strap 2 and plug 6 cooperate with each other to be installed in the flat cavity 5 of the base 1 in an interference fit manner, and can be repeatedly installed and removed. When the static friction generated by the elastic strap's interference fit is significantly greater than the elastic strap's normal operating tension, a reliable assembly connection is achieved.

DETAILED DESCRIPTION

[0029] The technical implementation of the present invention is further described below in conjunction with the accompanying drawings.

[0030] Elastic strap connection structure example 1: includes a base 1, an elastic strap 2, a hole slot 3 and a bolt 4, and its structure is as follows Figure 4 shown.

[0031] The hole slot 3 is located at one end of the base 1 and is a transverse hole slot with a narrow opening, the opening width of which is significantly smaller than the maximum cross-sectional width of the hole slot 3 .

[0032] The bolt 4 is a columnar object made at the end of the elastic strap.

[0033] The cross-sectional shapes of the hole 3 and the bolt 4 match each other and can be implemented in a variety of different shapes. To simplify the description, this specification only takes a circular cross-sectional shape as an example.

[0034] The bolt 4 is assembled into the slot 3 from the side of the base 1 using an interference fit, and the elastic strap 2 passes through the narrow opening of the slot 3. Because the narrow opening of the slot 3 is much smaller than the cross-sectional width of the bolt 4, even if the strap 2 is subjected to a large tensile force along its length, the bolt 4 will not fall out of the narrow opening of the slot 3.

[0035] When the elastic strap 2 is normally worn, it generally only bears a small working tension in the length direction, and there is almost no additional force in the installation direction of the bolt 4. Therefore, only a slight interference fit between the hole groove 3 and the bolt 4 is required to reliably install the elastic strap 2 on the base 1.

[0036] When the elastic strap 2 needs to be removed from the base 1, it is only necessary to manually apply appropriate lateral pulling force at the strap connection to remove the elastic strap 2 and the bolt 4 from the hole 3. The advantage of the elastic strap connection structure example 1 is that the structure is simple and the disassembly and assembly process can be completed quickly by hand.

[0037] Elastic strap connection structure example 2: includes a base 1, an elastic strap 2, a flat cavity 5 and a plug 6, such as Figure 5 shown.

[0038] The flat cavity 5 is located at one end of the base 1 and has a longer cavity depth. Figure 6 As shown, it can be used to accommodate the elastic strap 2 and the plug 6.

[0039] The elastic strap 2 and the plug 6 are assembled into the flat cavity 5 in an interference fit. By selecting the plug 6 of appropriate thickness and length, the elastic strap 2 can generate a high static friction force in the flat cavity 5, while the elastic strap 2 only needs to withstand a small working tension during normal wear.

[0040] Because the elastic strap 2 has the characteristics of absorbing and reducing instantaneous overload tension, and the plug 6 has a long insertion depth, the elastic strap 2 and the plug 6 can only be completely pulled out of the flat cavity 5 by continuous and strong pulling backward. In addition, because the elastic strap 2 is wrapped around the outside of the plug 6, and the direction of the working tension that the elastic strap 2 bears during normal use is roughly opposite to the direction of the plug 6's escape, the elastic strap 2 has the function of preventing the plug 6 from escaping from the flat cavity 5. Figure 8 As shown, the elastic strap connection structure example 2 described in the present invention has higher installation reliability.

[0041] When the elastic strap 2 becomes dirty or loose due to long-term use and needs maintenance, the elastic strap 2 can be pulled out with force and then cleaned, adjusted to the tightness (including cutting the elastic strap 2 to length) or replaced as needed. After reassembly, the elastic strap 2 can be restored to its original function. If the elastic strap 2 is only slightly loose, there is no need to disassemble it. The plug 6 can be pushed deeper into the flat cavity 5 to quickly adjust the tightness of the elastic strap 2.

[0042] In addition, the elastic strap 2 and the plug 6 can also be arranged in the flat cavity 5 as follows: Figure 7 The assembly method shown is optional for users Figure 5 or Figure 7 The elastic strap is installed as shown in the figure.

[0043] Application of the utility model

[0044] The elastic strap connection structure example 1 and the elastic strap connection structure example 2 described in the present invention can be used alone or in combination with each other, and can also be used in combination with other traditional elastic strap connection structures (such as screw fixing and adhesive fixing methods) to form a Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 Various forms of mobile phone auxiliary holding devices are shown in.

[0045] An auxiliary holding device for an electronic mobile terminal includes an elastic strap connection structure example 1 and an elastic strap connection structure example 2, such as Figure 8 The characteristic of the invention is that the elastic strap can be easily installed and removed and the tightness can be adjusted.

[0046] An auxiliary holding device for an electronic mobile terminal includes two elastic strap connection structures, such as Figure 9 The characteristic of this type of strap is that it is very easy to assemble and disassemble the elastic strap, but it does not have the function of adjusting the tightness. It is suitable for users who are not sensitive to the cost of replacing the elastic strap and are more concerned about the hygiene or condition of the strap.

[0047] An auxiliary holding device for an electronic mobile terminal includes two elastic strap connection structures, such as Figure 10 Its characteristics are that the tightness adjustment and assembly are relatively convenient, but it occupies more space inside the base and may affect the expansion of other functions of the mobile phone auxiliary grip device.

[0048] An auxiliary holding device for an electronic mobile terminal includes an elastic strap connection structure example 1 and an elastic strap connection structure fixed by a screw, such as Figure 11 The characteristic of the present invention is that daily cleaning and maintenance of the elastic strap only requires installation and removal of the elastic strap connection structure example 1. However, when adjusting the tightness or replacing the strap, a screwdriver tool is required to install and remove the other end of the elastic strap, which is slightly inconvenient for maintenance.

[0049] An auxiliary holding device for an electronic mobile terminal includes an elastic strap connection structure example 2 and an elastic strap connection structure fixed by a screw, such as Figure 12 As shown. Its characteristic is that daily cleaning and tightness adjustment of the elastic strap only requires installation and removal of the elastic strap connection structure example 2. Although a screwdriver is required to install and remove the other end of the elastic strap when replacing it, under normal circumstances, the elastic strap's functional lifespan can reach several years, and the need for replacement is relatively rare, with little impact on daily use.

[0050] An auxiliary holding device for an electronic mobile terminal includes an elastic strap connection structure example 2 and an elastic strap connection structure with an adhesive fixing method, such as Figure 13 The characteristic of this device is that although one end of the elastic strap cannot be replaced due to permanent adhesive fixation, daily cleaning, maintenance, and tightness adjustment of the elastic strap are very convenient. Under normal use, a well-maintained elastic strap can have a functional service life of several years and generally will not have a substantial impact on the functional service life of the auxiliary mobile phone grip device.

[0051] Relatively speaking, Figure 8 It is a combined implementation plan with better comprehensive performance. Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 This is a combined implementation scheme with suboptimal overall performance, but its maintainability is still significantly better than the traditional non-detachable or fully screw-fixed shoulder-strap mobile phone auxiliary grip device.

[0052] The mobile phone auxiliary holding device described in the present invention can also be combined with the existing mobile phone rectangular bracket technology to form a Figure 14 、 Figure 15 The strap-type mobile phone auxiliary holding device with a bracket function is shown. Figure 14 、 Figure 15 The rectangular bracket 7 can not only be used to support the mobile phone sideways or vertically when it is in the open state, but also the bracket frame can be used to form an additional anti-slip protection for the elastic strap connection structure example 1 or the elastic strap connection structure example 2 described in the utility model when the bracket is closed.

[0053] Advantages of the present invention

[0054] The mobile phone auxiliary grip device described in this utility model utilizes a self-tightening elastic strap, which provides a comfortable grip and a strong anti-slip performance without the need to deliberately hold the phone. It also has the advantage of single-handed full-screen touch control. Furthermore, because the elastic strap utilizes a removable technology solution, users can clean and adjust the tightness of the elastic strap as needed for maintenance. Some technical combination implementations also allow the elastic strap to be replaced. Furthermore, when combined with existing rectangular mobile phone holder technology, this utility model can be used for a wider range of functions and applications, comprehensively improving the comfort, convenience, and safety of people when using mobile phones, and has broad application prospects and social benefits.
