DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] When the following description refers to or is directed to a particular figure, it is for emphasis that most of the material set forth in the subsequent description is shown in that particular figure, but the subsequent description is not limited to that particular figure.

[0009] Please refer to Fig. 1 to Fig. 6. Fig. 1 to Fig. 3 are exploded schematic views of the control hand grip kit for a mobile phone (e.g., a smartphone) of the present invention from different viewpoints, Fig. 4 and Fig. 5 are schematic views of the control hand parts of the mobile phone of the present invention from different viewpoints, and Fig. 6 is a schematic side view of the control hand grip kit for a mobile phone of the present invention. Note that in this embodiment, a mobile phone is used as an example of a mobile terminal for explanation, but the mobile terminal is a control hand grip kit for a mobile phone of the present invention. G It is not limited to mobile phones as long as it can be used in lip kits.

[0010] The hand grip kit 100 for controlling a mobile phone of the present invention is suitable for holding a mobile phone 200 and connecting to the mobile phone 200. The hand grip kit 100 for controlling a mobile phone includes a hand grip body 1, a control module 2, two handle auxiliary accessories 3, and two magnetic shield members 4. The hand grip body 1 includes a connection mechanism 11 and two grip parts 12. The two grip parts 12 are connected to each other by the connection mechanism 11. The specific shape, internal structure, etc. of the connection mechanism 11 are not limited here.

[0011] In a specific embodiment, the connection mechanism 11 includes two connection parts 111 and a pivot part 112. Of the two grip parts 12, one grip part 12 is connected to one side of the pivot part 112 via the connection part 111, and the other grip part 12 is connected to the other side (opposite side) of the pivot part 112 via the connection part 111. Each grip part 12 and the connection part 111 connected thereto can rotate relative to the other grip part 12 via the pivot part 112. For example, in this embodiment, the axial direction 112L of the pivot part 112 is along the short side direction of the connection mechanism 11, and each grip part 12 and the connection part 111 connected thereto can rotate relative to the other grip part 12 via the pivot part 112 in a rotation direction around the axial direction of the pivot part 112. The connector 13 is installed on one grip part 12. The connector 13 is for connecting to a connection port of the mobile phone 200, and may be, for example, a Type-C standard USB or an Apple Lightning connector, but is not limited to these.

[0012] In each embodiment, the connection mechanism 11 may not include the pivot part 112, and may include parts such as a slide, slider, etc., and the two grip parts 12 can move toward or away from each other (in the longitudinal direction of the connection mechanism 11) through the parts such as a slide, slider, etc. After the two grip parts 12 are operated and moved toward each other through the slide, slider, etc., the overall width of the hand grip body 1 can be reduced, which makes it easier for the user to carry it.

[0013] In different embodiments, a spring or other component may be installed in the handgrip body 1. When at least one gripping portion 12 is pulled in a direction away from the other gripping portions 12, the spring in the gripping portion 12 generates an elastic restoring force. This elastic restoring force functions to ensure that the two gripping portions 12 hold the mobile phone 200 firmly.

[0014] Each grip part 12 may include a plurality of operation parts, for example, a plurality of push keys 121 and at least one joystick 122. The control module 2 is installed in the hand grip body 1. The control module 2 may include, for example, a circuit board, a microprocessor, a communication chip, etc., and when any push key 121 or joystick 122 in any grip part 12 is operated, the control module 2 can generate a corresponding control signal. Then, the control module 2 can transmit the control signal to the mobile phone 200 through the connector 13 or a wireless communication method. In this way, the mobile phone 200 can be operated. For example, after a user connects the connection port of the mobile phone 200 to the connector 13, the user can hold the two grip parts 12 with both hands and play a game or the like in the mobile phone 200 by operating the multiple push keys 121 and joystick 122 included in the two grip parts 12. In a different embodiment, one of the operating components included in the grip portion 12 may be a touchpad, and when a user operates the touchpad, the control module 2 generates a corresponding control signal and transmits the control signal to the mobile phone 200.

[0015] As shown in FIG. 3, both ends of each gripping portion 12 are defined as a front end 123 and a rear end 124. The thickness of each gripping portion 12 varies less than 20% from the front end 123 to the rear end 124. For example, if the minimum thickness D1 at the front end 123 of each gripping portion 12 is 5 cm, the maximum thickness D2 at the rear end 124 of each gripping portion 12 may be about 4-6 cm. In other words, the thickness of each gripping portion 12 varies less from the front end 123 to the rear end 124. With this design, the handgrip body 1 is convenient to carry, but in the actual use process, the user will get a relatively poor gripping feeling, and the operation of the push keys 121 and the joystick 122 will also have a relatively poor experience.

[0016] It is particularly noteworthy that the size of the user's hands varies from person to person, so that a user with small hands may not experience a problem of poor grip when gripping the hand grip body 1. However, a user with large hands may experience a problem of poor grip when gripping the hand grip body 1. A user with poor grip can attach two handle auxiliary accessories 3 to the rear side 125 of each grip part 12. In this way, the two handle auxiliary accessories 3 increase the thickness of the rear end part 124 of each grip part 12, so that the grip feeling when the user grips the hand grip kit 100 for controlling a mobile phone is improved, and at the same time, the operability of the hand grip kit 100 for controlling a mobile phone is also improved.

[0017] As shown in Figs. 1 to 3, in detail, two first magnetic attraction members 126 and two first engagement structures 127 are provided on the rear side 125 of each gripping portion 12 (the surface opposite to the surface on which a plurality of operation components are provided). Each of the two first engagement structures 127 is, for example, a groove, and each of the first magnetic attraction members 126 is a magnet or a structure capable of being attracted to a magnet, and each of the first magnetic attraction members 126 is disposed corresponding to one of the grooves (in the first engagement structures 127). The number and arrangement positions of the first magnetic attraction members 126 included in each gripping portion 12, the number and arrangement positions of the first engagement structures 127, the shape of the first engagement structures 127, and the like are not limited to those shown in the figures.

[0018] Each handle assist accessory 3 includes an accessory body 31, two second magnetic attraction members 32, two second engagement structures 33, and one magnetic shield member 4. The number and arrangement positions of the second magnetic attraction members 32, the second engagement structures 33, and the magnetic shield member 4 included in each handle assist accessory 3 can be changed according to actual needs and are not limited to those shown in the drawings.

[0019] The two ends of each accessory body 31 are defined as a front end 31A and a rear end 31B, and the thickness of the section of the accessory body 31 gradually increases from the front end 31A to the rear end 31B, and when each accessory body 31 is fixed to the rear side 125 of the grip part 12, the rear end 31B of the accessory body 31 is located at the rear end 124 of the grip part 12. For example, as shown in Fig. 6, the front end 31A of the accessory body 31 has a minimum thickness D3, the position of the accessory body 31 close to the rear end 31B has a maximum thickness D4, and the thickness of the accessory body 31 gradually increases from the position of the minimum thickness to the position of the maximum thickness.

[0020] Each second magnetically attractive member 32 and the corresponding first magnetically attractive member 126 are members that attract each other by magnetic force, for example, the second magnetically attractive member 32 is a strong magnet, and the corresponding first magnetically attractive member 126 is a member that is attracted by the magnet. Conversely, if the first magnetically attractive member 126 is a strong magnet, the second magnetically attractive member 32 is a member that is attracted by the magnet.

[0021] Each of the second engagement structures 33 can be engaged with the corresponding first engagement structure 127, and each of the accessory main bodies 31 can be connected with the two first magnetic attraction members 126 and the two first engagement structures 127 in one of the grip parts 12 via the two second magnetic attraction members 32 and the two second engagement structures 33, and thus the accessory main body 31 can be fixed to the rear side 125 of the grip part 12. For example, the outer shape of each of the second engagement structures 33 can be said to resemble a hollow cylindrical structure, and each of the second magnetic attraction members 32 can be correspondingly installed in the hollow cylindrical structure. Therefore, when each of the hollow cylindrical structures (second engagement structures 33) and the corresponding recesses (first engagement structures 127) engage with each other, the second magnetic attraction members 32 and the first magnetic attraction members 126 are mutually attracted to each other.

[0022] As described above, each accessory body 31 is fixed to the rear side 125 of the two gripping parts 12 through the two second magnetic attraction members 32 and the two second engagement structures 33. This causes the rear end 31b of each accessory body 31 to correspond to a position close to the rear end 124 of the gripping part 12. As a result, when a user grips the mobile phone control hand grip kit 100, the user simultaneously grips the two accessory bodies 31 and the two gripping parts 12. This allows the user to obtain a relatively good gripping feeling. In particular, a user with a large palm can obtain a relatively good gripping feeling.

[0023] 3 and 6, specifically, when a user grips the handgrip body 1 shown in FIG. 3, the thickness D2 of the rear end 124 of the handgrip body 1 is small, so that a user with a large palm may get a relatively bad gripping feeling when gripping the handgrip body 1 shown in FIG. 3. In this case, the user can attach the handle auxiliary accessory 3 to the rear side 125 of the gripping part 12. And, when a user grips the handgrip kit 100 for controlling a mobile phone shown in FIG. 6, the thickness D5 of the rear end 124 of the handgrip kit 100 for controlling a mobile phone is larger than the thickness D2 shown in FIG. 3, so that the user can get a relatively good gripping feeling.

[0024] At least one magnetic shield member 4 is installed around the second magnetic attraction member 32 of each handle auxiliary accessory 3 and its corresponding first magnetic attraction member 126. Each magnetic shield member 4 is used to reduce the influence of the magnetic field of the adjacent first magnetic attraction member 126 and second magnetic attraction member 32 on the mobile phone 200. In a specific application example, the magnetic shield member 4 is a magnetic shield plate, a magnetic shield block, etc. In practice, the magnetic shield member 4 can be arranged around the magnet member. For example, when the first magnetic attraction member 126 is a magnet, the magnetic shield member 4 is arranged around the grip part 12 in close proximity to the first magnetic attraction member 126. Conversely, when the second magnetic attraction member 32 is a magnet, the magnetic shield member 4 is arranged around the second magnetic attraction member 32 of the accessory body 31.

[0025] It should be particularly emphasized that currently popular smartphones usually have multiple antennas or related magnetically sensitive components at the top (one end of the receiver) and bottom, so that when the smartphone is placed in the mobile phone control hand grip kit 100 of the present invention, the antennas or magnetically sensitive components of the smartphone approach the first magnetically attractive member 126 and the second magnetically attractive member 32. Therefore, if the magnetic shielding member 4 is not installed around the first magnetically attractive member 126 or the second magnetically attractive member 32, the magnetic field of the magnet (the first magnetically attractive member 126 or the second magnetically attractive member 32) may cause interference with the antennas or magnetically sensitive components of the smartphone, which may cause some functions of the smartphone to not operate normally.

[0026] In light of the above, the hand grip kit for controlling a mobile phone of the present invention, by designing two handle auxiliary accessories, a first magnetic attraction member, a second magnetic attraction member, a magnetic shielding member, etc., can not only increase the tactile and operable feeling of a user (especially a user with a relatively large palm) when holding the hand grip kit for controlling a mobile phone, but also prevent the first magnetic attraction member and the second magnetic attraction member from interfering with the associated antenna and magnetic elements of the mobile phone.

[0027] Please refer to Figures 7 and 8. These are exploded schematic views from different viewpoints of another embodiment of the handgrip kit for controlling a mobile phone of the present invention. The first difference between this embodiment and the above-mentioned embodiment is that the handgrip body 1 includes at least one first rechargeable battery 14. One first charging connection member 128 is installed in each grip part 12. The number and installation position of the first rechargeable batteries 14 installed in the handgrip body 1 are not limited to those shown in the drawings.

[0028] Each handle auxiliary accessory 3 includes at least one second rechargeable battery 34 and a second charging connection member 35. When each handle auxiliary accessory 3 is fixed to the rear side 125 of the two gripping parts 12, each second charging connection member 35 is connected to the corresponding first charging connection member 128, and the control module 2 can perform the function of charging the second rechargeable battery 34 to the first rechargeable battery 14, or charging the first rechargeable battery 14 to the second rechargeable battery 34. The specific structures of the first charging connection member 128 and the second charging connection member 35 may be, for example, various electrical connection structures, such as various metal contacts.

[0029] In this embodiment, one second rechargeable battery 34 and one second charging connection member 35 are installed in each accessory body 31, but it should be explained that this is not limited to this. In a different embodiment, the second rechargeable battery 34 and the second charging connection member 35 may be installed only in one of the two accessory bodies 31, and the second rechargeable battery 34 and the second charging connection member 35 may not be installed in the other accessory body 31. Similarly, in this embodiment, the first charging connection member 128 is installed in each grip portion 12, but this is not limited to this, and in a different embodiment, the first charging connection member 128 may be installed only in one grip portion 12, and the first charging connection member 128 may not be installed in the other grip portion 12.

[0030] In one modified embodiment, the control module 2 can determine whether the first rechargeable battery 14 charges the second rechargeable battery 34 or whether the second rechargeable battery 34 charges the first rechargeable battery 14 based on the remaining battery power of the first rechargeable battery 14 and the remaining battery power of each second rechargeable battery 34.

[0031] Specifically, after the user fixes the two handle auxiliary accessories 3 to the two gripping parts 12, the control module 2, for example, first obtains the remaining battery power of the first rechargeable battery 14 and the remaining battery power of the second rechargeable battery 34, and then, when the control module 2 determines that the remaining battery power of the first rechargeable battery 14 is a predetermined percentage (e.g., 80%) or more and that the remaining battery power of the second rechargeable battery 34 is a predetermined percentage (e.g., 20%) or less, the control module 2 can, for example, control the first rechargeable battery 14 to charge the second rechargeable battery 34. Conversely, when the control module 2 determines that the remaining battery power of the second rechargeable battery 34 is a predetermined percentage (e.g., 80%) or more and that the remaining battery power of the first rechargeable battery 14 is a predetermined percentage (e.g., 20%) or less, the control module 2 can control the second rechargeable battery 34 to charge the first rechargeable battery 14. Of course, the control module 2 can be designed and modified according to actual requirements to determine the charging method for the first rechargeable battery 14 and the second rechargeable battery 34 based on the remaining battery power of the first rechargeable battery 14 and the second rechargeable battery 34. The above description is only an example.

[0032] The second difference between this embodiment and the above embodiment is that the handgrip body 1 is provided with a charging port 15, which is electrically connected to the control module 2, and an external power source can charge the first rechargeable battery 14 through the charging port 15. When the charging port 15 is connected to an external power source, the control module 2 controls the second rechargeable battery 34 not to charge the first rechargeable battery 14. In practical application, when the charging port 15 is connected to an external power source, when the remaining battery level of the first rechargeable battery 14 reaches a predetermined percentage (e.g., 100%) or exceeds a predetermined percentage (e.g., 90%), the control module 2 can control the external power source to charge the second rechargeable battery 34. Of course, in different embodiments, when the charging port 15 is connected to an external power source, the control module 2 can also control the external power source to charge the first rechargeable battery 14 and the second rechargeable battery 34 simultaneously.

[0033] The third difference between this embodiment and the above embodiment is that each accessory body 31 is provided with a processor 36, a battery level indicator 37, and a charging port 38. The processor 36 is electrically connected to the second rechargeable battery 34, and the processor 36 controls the battery level indicator 37 based on the battery level of the second rechargeable battery 34, so that the battery level indicator 37 can display the battery level of the second rechargeable battery 34. That is, the user can use the relevant connecting line to connect to the charging port 15 of each accessory body 31, and an external power source can charge the second rechargeable battery 34, and the user can see the battery level indicator 37 to know whether the second rechargeable battery 34 is fully charged. The second rechargeable battery 34 is electrically connected to the charging port 38, and an external power source can charge the second rechargeable battery 34 through the charging port 38.

[0034] The remaining battery level indicator 37 can also simply indicate whether the second rechargeable battery 34 is already fully charged or not, or can also indicate the remaining battery level percentage of the second rechargeable battery 34. The present invention is not limited to this.

[0035] A number of different characteristics different from the previous embodiments presented in the above embodiment do not have to exist at the same time, and each different technical characteristic can also form a new embodiment together with the previous embodiments.

[0036] The contents disclosed above are merely preferred embodiments of the present invention, and do not limit the scope of the claims of the present invention. Therefore, all equivalent technical modifications made based on the contents of the specification and accompanying drawings of the present invention are intended to be included in the scope of the claims of the present invention.
