[0031] Electronic stylus products that use vibration motors on the market currently have extremely strict requirements on the size of the motor to ensure that it can fit into the compact space inside the stylus. The common assembly method is to clamp it with two different brackets at the front and back, and to attach foam to fill the size and assembly tolerances, and to reduce the impact of the motor vibration on the internal parts of the pen body.

[0032] However, the existing stylus pen assembly structure usually involves multiple materials, and materials such as foam or high-temperature glue need to be assembled around the vibration motor to absorb dimensional tolerances, which makes the stylus pen assembly process take a lot of time, thereby increasing material and assembly costs.

[0033] The invention provides a motor fixing structure of a touch pen.

[0034] See also Figure 1 , in one embodiment of the present invention, the motor fixing structure of the stylus pen includes a pen body 1, a positioning assembly 2, a bracket assembly 33 and a driving member 4;

[0035] In this embodiment, the pen body 1 has a receiving cavity 11 for accommodating the positioning assembly 2, the bracket assembly 33 and the driving member 4. The pen body 1 can be in a hollow cylindrical shape, so that it is more convenient for users to hold, thereby reducing the fatigue of the user's hands when writing for a long time. The positioning assembly 2 includes a mounting sleeve 22 and a stopper 21 arranged in the mounting sleeve 22. The stopper 21 is assembled to the end of the mounting sleeve 22 away from the bracket assembly 33 through a dispensing process, thereby improving the stability of the connection between the stopper 21 and the mounting sleeve 22. The bracket assembly 33 is assembled inside the mounting sleeve 22. The bracket assembly 33 corresponds to the stopper 21 along the axial direction of the mounting sleeve 22 and is arranged at intervals, so that a certain spacing distance is maintained between the stopper 21 and the bracket assembly 33, so that the driving member 4 can be stably abutted between the stopper 21 and the bracket assembly 33, thereby improving the stability of the driving member 4 in the mounting sleeve 22, thereby effectively utilizing the space inside the pen body 1, thereby ensuring the compactness and practicality of the overall structure of the pen body 1. The driving member 4 includes a motor 42 and an elastic connecting arm 41 connected to the motor 42. The bracket assembly 33 is also used to install the electronic component 5. By setting the two ends of the motor 42 to abut against the stopper 21 and the bracket assembly 33 respectively, it is more convenient for the elastic connecting arm 41 to extend into the bracket assembly 33 and electrically connect with the electronic component 5. The elastic connecting arm 41 can be directly molded into the required shape and length by a mold to avoid the incoming material size and assembly tolerance generated between the motor 42 and the bracket assembly 33. Compared with the existing assembly method of clamping by two brackets 31, the present application does not need to add additional foam, high-temperature glue and other materials to absorb the incoming material size and assembly tolerance, thereby reducing material costs and reducing the time cost during the assembly process. In addition, the elastic connecting arm 41 can adjust the interference amount according to the actual assembly requirements, so as to ensure that the elastic connecting arm 41 is fixed to the mounting sleeve 22, so that the elastic connecting arm 41 will not make abnormal noise or shake during use.

[0036] The technical solution of the present invention adopts the two ends of the motor 42 to abut against the stopper 21 and the bracket assembly 33 respectively, and the motor 42 is electrically connected to the electronic component 5 through the elastic connecting arm 41. The elastic connecting arm 41 can be directly molded into the required shape and length through a mold, which can avoid the use of additional materials such as foam and high-temperature glue due to size and assembly tolerance problems when assembling the motor 42 and the bracket assembly 33, thereby effectively reducing material costs and shortening the time required for the assembly process. The elastic connecting arm 41 can adjust the interference amount according to the assembly requirements between the motor 42 and the bracket assembly 33, so as to ensure that the elastic connecting arm 41 is firmly positioned in the installation sleeve 22, thereby ensuring that the elastic connecting arm 41 has no abnormal sound or instability during use.

[0037] like Figures 2 to 5As shown, in this embodiment, the elastic connecting arm 41 includes a first connecting section 411 and a second connecting section 412 that are connected to each other, the first connecting section 411 is connected to the motor 42, the second connecting section 412 is arranged at an end of the first connecting section 411 away from the motor 42, and the second connecting section 412 is provided with a connector 4121, and the connector 4121 is used to connect the electronic component 5.

[0038] In this embodiment, in order to facilitate the electrical connection between the motor 42 and the electronic component 5 in the bracket assembly 33, a first connecting section 411 is provided to be electrically connected to the motor 42, and the first connecting section 411 is electrically connected to the electronic component 5 through the second connecting section 412, thereby ensuring that the motor 42 can be electrically connected to the electronic component 5 in the narrow space inside the mounting sleeve 22. A connector 4121 is provided at one end of the second connecting section 412 close to the electronic component 5, and the second connecting section 412 is electrically connected to the electronic component 5 through the connector 4121, thereby improving the flexibility of the assembly process of the second connecting section 412 and the electronic component 5.

[0039] like Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the elastic connecting arm 41 also includes a bending section 413 connected between the first connecting section 411 and the second connecting section 412, the first connecting section 411 is arranged on the side of the motor 42 close to the mounting sleeve 22, the first connecting section 411 and the second connecting section 412 are opposite and spaced apart along the radial direction of the mounting sleeve 22, and the bending section 413 is bent from the first connecting section 411 toward the second connecting section 412.

[0040] In this embodiment, in order to ensure the stability of the electronic component 5 in the bracket assembly 33, the electronic component 5 can be arranged at the radial center of the bracket assembly 33. Since the first connecting section 411 is located on a side wall of the motor 42 close to the mounting sleeve 22, the first connecting section 411 and the second connecting section 412 are arranged opposite to each other and spaced apart along the radial direction of the mounting sleeve 22, and the bending section 413 can be provided with elasticity, and the first connecting section 411 is connected to the second connecting section 412 by bending the bending section 413 multiple times, thereby facilitating the connection between the first connecting section 411 and the second connecting section 412. The interference amount of the elastic connecting arm 41 can be adjusted by bending the bending section 413 according to the distance between the first connecting section 411 and the second connecting section 412, so as to ensure that the elastic connecting arm 41 is stable in the mounting sleeve 22 while avoiding abnormal noise or shaking during use.

[0041] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the bracket assembly 33 includes a bracket 31 and a cover plate 33, the bracket 31 is connected to the cover plate 33, an installation station is formed between the bracket 31 and the cover plate 33, the connector 4121 and the electronic component 5 are both arranged in the installation station, and the bracket 31 abuts against the motor 42.

[0042] In this embodiment, in order to enable the electronic component 5 to be more stably assembled inside the bracket assembly 33, an installation station is formed between the bracket 31 and the cover plate 33, so that the installation station provides necessary space for the installation of the electronic component 5 and the connector 4121, so that the electronic component 5 and the connector 4121 can be more stably fixed in the bracket assembly 33, thereby reducing the risk of failure caused by looseness or poor contact of the electronic component 5 and the connector 4121, and thus improving the service life of the electronic component 5.

[0043] In this embodiment, a fixing hook for fixing the electronic component 5 is provided on one end surface of the bracket 31 close to the electronic component 5. Two fixing hooks can be provided and respectively installed on the left and right sides of the bracket 31, so that the electronic component 5 is firmly clamped between the two fixing hooks and the bracket 31, thereby improving the stability of the connection between the electronic component 5 and the bracket 31, and then effectively preventing the electronic component 5 from being displaced or falling off during transportation or use, thereby ensuring the performance and safety of the present application.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, the motor fixing structure of the stylus pen also includes a fastener 6, a mounting post 32 is provided at one end of the bracket 31 away from the motor 42, the cover plate 33 is provided with a connecting portion 331 corresponding to the mounting post 32, and the fastener 6 is installed on the mounting post 32 through the connecting portion 331.

[0045] In this embodiment, by respectively providing a mounting column 32 and a connecting portion 331 on the bracket 31 and the cover plate 33, and by providing a fastener 6 that passes through the connecting portion 331 and is assembled on the mounting column 32, the stability of the connection between the bracket 31 and the cover plate 33 is significantly improved, thereby reducing the possibility of the connection between the bracket 31 and the cover plate 33 loosening or falling off due to vibration or external force; at the same time, it also facilitates the disassembly and maintenance of the bracket 31 and the cover plate 33, so that the user can easily check or replace components when necessary, further improving the practicality and life of the present application.

[0046] In this embodiment, the electronic component 5 may have a mounting hole at one end close to the mounting post 32, and the electronic component 5 is sleeved on the mounting post 32 through the mounting hole, so that the electronic component 5 is fixed in the installation station, thereby further improving the stability of the electronic component 5 assembled on the bracket 31. It should be noted that the mounting hole is not marked in the drawings of the specification.

[0047] In this embodiment, the fastener 6 may be a bolt, a screw, a pin, a screw, etc. The fastener 6 may pass through the connecting portion 331 and be threadedly connected to the mounting column 32 , thereby facilitating the installation and removal of the bracket 31 and the cover plate 33 .

[0048] like Figure 2 As shown, in this embodiment, the motor fixing structure of the stylus pen further includes a buffer portion 7 , and the buffer portion 7 is disposed on a side of the second connecting section 412 close to the cover plate 33 .

[0049] In this embodiment, the function of the buffer assembly is to absorb the vibration transmitted by the motor 42, thereby preventing the vibration from being transmitted to the bracket assembly 33 through the elastic connecting arm 41, thereby preventing the bracket assembly 33 from causing vibration of the electronic component 5. The buffer portion 7 can be made of materials such as foam or high-temperature glue. The installation position of the buffer portion 7 can be located on the side of the second connecting section 412 away from the connector 4121, so that it is more convenient for the side of the second connecting section 412 away from the connector 4121 to abut against the cover plate 33 through the buffer portion 7.

[0050] like Figure 1 As shown, in this embodiment, one end of the mounting sleeve 22 close to the bracket assembly 33 has a notch 221 for allowing the cover plate 33 and the fastener 6 to be exposed outside the mounting sleeve 22 .

[0051] In this embodiment, a notch 221 is provided at one end of the mounting sleeve 22 close to the bracket assembly 33 so that the cover plate 33 and the fastener 6 are exposed outside the mounting sleeve 22, thereby facilitating the user to disassemble the cover plate 33 and the fastener 6 after removing the mounting sleeve 22.

[0052] In this embodiment, one end of the mounting sleeve 22 close to the motor 42 has a limiting opening connected to the notch 221, and the elastic connecting arm 41 is engaged in the limiting opening, so that the limiting opening limits the circumferential rotation of the elastic connecting arm 41 along the mounting sleeve 22, thereby effectively preventing the elastic connecting arm 41 from rotating unnecessarily during operation. It should be noted that the limiting opening is not marked in the drawings of the specification.

[0053] like Figure 1 As shown, in this embodiment, the stop member 21 and / or the mounting sleeve 22 are metal members made of metal material.

[0054] In this embodiment, the metal material can be steel or profiles. By setting the motor 42 in direct contact with the stopper 21, there is no need to add any additional structure to achieve the grounding of the motor 42, and the risk of electromagnetic interference can be avoided, thereby simplifying the internal structure of the mounting sleeve 22, thereby reducing the production cost of the present application. In addition, by setting the motor 42 in direct contact with the stopper 21, it can be ensured that the vibration generated by the vibration of the motor 42 is efficiently and directly transmitted to the pen tip, so that the user can enjoy a smoother and more natural writing experience during use, thereby further improving the comfort of the writing experience.

[0055] like Figure 1 and Figure 3 As shown, in this embodiment, the stop member 21 is in the shape of a hollow cylinder, and the stop member 21 is bonded to the inner circumference of the installation sleeve 22 .

[0056] In this embodiment, in order to improve the fit between the stopper 21 and the mounting sleeve 22, the stopper 21 and the mounting sleeve 22 can both be configured as hollow cylinders. The stopper 21 is bonded to the inner circumference of the mounting sleeve 22 away from the bracket assembly 33 by a glue dispensing process, thereby improving the stability of the connection between the stopper 21 and the mounting sleeve 22.
