Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
[0035] Please refer to Figures 1 to 5 In some embodiments, the stylus pen 100 includes: a housing 200, a battery 300, a circuit board 400, a tail cover 500 and an elastic member 600. The housing 200 is made of a conductive material, and the housing 200 has a storage cavity 210. The conductive material can be a metal material, such as copper, aluminum, iron, silver, gold, etc. Copper is one of the most commonly used conductive metals due to its good conductivity and relatively low price. The conductive material can also be a composite material, such as conductive rubber and conductive plastic. The battery 300 is disposed in the storage cavity 210. The battery 300 is a device for energy conversion and storage, which converts chemical energy or physical energy into electrical energy through chemical reactions to meet the power requirements of various electrical devices. The battery 300 has many types, such as zinc-carbon batteries, alkaline batteries, nickel-hydrogen batteries, lithium-ion batteries and lithium polymer batteries. The circuit board 400 is disposed in the storage cavity 210, and the circuit board 400 is electrically connected to one end of the battery 300. Specifically, the circuit board 400 can be electrically connected to the positive electrode of the battery 300, or the circuit board 400 can be electrically connected to the negative electrode of the battery 300. The tail cover 500 is made of a conductive material, and the conductive material can be a metal material, such as copper, aluminum, iron, silver, gold, etc. Copper has become one of the most commonly used conductive metals due to its good conductivity and relatively low price. The conductive material can also be a composite material, such as conductive rubber and conductive plastic. The tail cover 500 is connected to the housing 200, and the tail cover 500 is electrically connected to the other end of the battery 300, so that one end of the battery 300 is electrically connected to the housing 200. In addition, one end of the battery 300 can also be directly electrically connected to the housing 200. Specifically, the tail cover 500 can be electrically connected to the positive electrode of the battery 300, or the tail cover 500 can be electrically connected to the negative electrode of the battery 300. The elastic member 600 is made of a conductive material, and the conductive material can be a metal material, such as copper, aluminum, iron, silver, gold, etc. Copper is one of the most commonly used conductive metals due to its good conductivity and relatively low price. The conductive material can also be a composite material, such as conductive rubber and conductive plastic. The elastic member 600 can be a spring or a metal spring. Please refer to Figure 2, the elastic member 600 is arranged in the storage cavity 210, and the elastic force of the elastic member 600 makes one end of the elastic member 600 abut against the circuit board 400, and the other end abuts against the shell 200. Specifically, one end of the elastic member 600 abuts against the circuit board 400, and the other end of the elastic member 600 abuts against the shell 200, so that the circuit conduction between the shell 200 and the circuit board 400 can be achieved. In the prior art, the shell 200 and the circuit board 400 need to be electrically connected by welding, which will increase the additional manufacturing cost. In the present application, since the elastic member 600 does not need to be welded, the elastic member 600 connects the shell 200 and the circuit board 400 with the help of its own elastic force. Therefore, the stylus pen 100 of the present application does not need to add the step of welding the circuit board 400, thereby saving costs. Specifically, the stylus pen 100 can have a lower manufacturing cost.
[0036] It is necessary to add that please refer to Figure 1 After the circuit board 400 is electrically connected to the positive electrode of the battery 300, the negative electrode of the battery 300 is electrically connected to the tail cover 500, and the tail cover 500 can be electrically connected to the housing 200, and the housing 200 and the circuit board 400 are connected through the elastic member 600. Therefore, the current flows from the positive electrode of the battery 300 through the circuit board 400, and then flows from the circuit board 400 to the elastic member 600, and the current passes through the elastic member 600, the housing 200 and the tail cover 500 in sequence, and then returns to the negative electrode of the battery 300. In this way, through the cooperation of the housing 200, the tail cover 500 and the elastic member 600, the battery 300 can supply power to the circuit board 400.
[0037] It is further explained that the elastic member 600 can directly contact the circuit board 400 and the housing 200 under the elastic force, thereby realizing the electrical connection between the circuit board 400 and the housing 200. When installing the stylus pen 100, the setting of the elastic member 600 can also facilitate the installation of the staff, thereby improving the installation efficiency.
[0038] Furthermore, after the circuit board 400 is set in the storage cavity 210 of the housing 200, the circuit board 400 needs to be fixed to ensure that the circuit board 400 can still operate normally after the touch wall falls. Therefore, the circuit board 400 can be fixedly installed in the storage cavity 210. For details, please refer to Figure 1 and Figure 4In some embodiments, the stylus pen 100 further includes a bracket 700. The bracket 700 is disposed in the storage cavity 210, and the bracket 700 is fixedly connected to the housing 200, and the circuit board 400 is connected and fixed to the bracket 700. The bracket 700 is fixedly connected to the housing 200, so that the bracket 700 is fixed in the storage cavity 210, and the circuit board 400 can be fixedly connected to the bracket 700, so that the circuit board 400 is fixed in the storage cavity 210. In this way, when the stylus pen 100 is subjected to external impact, vibration, tilt and other factors, if the circuit board 400 is not firmly fixed, the components in the circuit may move relative to each other, resulting in unstable connection, loose circuit and other problems, thereby affecting the use effect and life of the product. If the circuit board 400 is firmly fixed in the housing 200, the circuit position can be locked to prevent movement caused by external factors, thereby enhancing the stability of the circuit board 400 and extending the service life of the stylus pen 100.
[0039] The two ends of the elastic member 600 mentioned above can respectively abut against the inner side of the housing 200 and the circuit board 400, thereby realizing the electrical connection between the circuit board 400 and the housing 200. When the elastic member 600 abuts against the circuit board 400 and the housing 200, the elastic member 600 is in a compressed state, which can make the elastic member 600 tightly abut against the housing 200 and the circuit board 400, thereby ensuring the stability of the electrical connection between the circuit board 400 and the housing 200. For further information, please refer to Figure 2 In some embodiments, the bracket 700 is provided with a fixing hole 710, and the elastic member 600 is provided in the fixing hole 710. The bracket 700 and the circuit board 400 are fixedly connected, so that the circuit board 400 is fixed on the bracket 700. After the fixing hole 710 is provided on the bracket 700, the installation of the elastic member 600 can be facilitated. That is, when installing the stylus pen 100, the circuit board 400 can be installed on the bracket 700 first, and then the elastic member 600 can be directly placed in the fixing hole 710, and finally the bracket 700 and the elastic member 600 can be placed in the storage cavity 210. The fixing hole 710 can facilitate the elastic member 600 to be aligned with the power supply part on the circuit board 400. If there is no fixing hole 710, it is difficult to align the elastic member 600 with the power supply part on the circuit board 400 when installing the elastic member 600 on the circuit board 400. Alternatively, when there is no fixing hole 710, even if the elastic member 600 is placed on the power supply part on the circuit board 400 first, when the elastic member 600 and the circuit board 400 are placed in the storage cavity 210, the elastic member 600 may be misaligned with the power supply part of the circuit board 400 during movement.
[0040] Further, after the elastic member 600 is arranged in the fixing hole 710, in order to ensure the stability of the elastic member 600 abutting against the circuit board 400 and the housing 200, the fixing hole 710 can be set as a stepped hole. Figure 2 and Figure 3 In some embodiments, the elastic member 600 includes a main body 610 and a protruding portion 620. The protruding portion 620 is connected to the main body 610, and the protruding portion 620 protrudes relative to one end of the main body 610. The shape of the elastic member 600 may be a "convex" shape, and the fixing hole 710 includes a first hole 711 and a second hole 712 that are interconnected. Along the thickness direction of the circuit board 400, the projection of the first hole 711 falls within the projection range of the second hole 712, and the cross-section of the fixing hole 710 may be a "convex" shape. The two ends of the main body 610 are respectively in contact with the hole walls of the circuit board 400 and the second hole 712, and the protruding portion 620 passes through the first hole 711 and protrudes relative to the first hole 711. In this way, when the elastic member 600 is installed in the fixing hole 710, the main body 610 can be located in the second hole 712, and the main body 610 can be pre-pressed to be in a compressed state. At this time, the two ends of the main body 610 respectively abut against the circuit board 400 and the hole wall of the second hole 712, which can ensure that the main body 610 is firmly abutted against the circuit board 400. When the protrusion 620 passes through the first hole 711 and protrudes, when the protrusion 620 abuts against the inner wall of the housing 200, the protrusion 620 will also be in a compressed state, so that the protrusion 620 can be tightly abutted against the inner wall of the housing 200. In this way, the elastic member 600 can tightly abut against the housing 200 and the current plate, ensuring that the electrical connection between the circuit board 400 and the housing 200 is relatively stable.
[0041] Further, the following describes how the bracket 700 is fixedly connected to the housing 200. Figure 4 In some embodiments, the stylus pen 100 further includes a pen tip 800, the pen tip 800 is connected to the housing 200, and the pen tip 800 and the bracket 700 are an integrated structure. Specifically, after the pen tip 800 and the bracket 700 are an integrated structure, the pen tip 800 can be threadedly connected to the housing 200, so that the pen tip 800 is installed on the housing 200, and the bracket 700 is set in the storage cavity 210. In addition, if the pen tip 800 and the bracket 700 are not an integrated structure, then when the bracket 700 is fixedly connected to the housing 200, it is necessary to weld or bond the bracket 700 to the housing 200, which is inconvenient to remove the bracket 700 from the housing 200. By threading the pen tip 800 to the housing 200, on the one hand, the bracket 700 can be fixedly connected to the housing 200, and on the other hand, it is also convenient to remove the bracket 700 from the housing 200.
[0042] Further, in some embodiments, the circuit board 400 is threadedly connected to the bracket 700. The specific way in which the circuit board 400 is threadedly connected to the bracket 700 can be that threaded holes are provided on both the circuit board 400 and the bracket 700, and screws are passed through the threaded holes of the circuit board 400 and the threaded holes of the bracket 700, so that the circuit board 400 can be fixed on the circuit board 400. The threaded connection has the following advantages: the threaded connection has the advantage of being easy to disassemble. This makes it more convenient to repair and replace parts, and improves the maintainability and flexibility of the equipment. Compared with other connection methods, the production cost of the threaded connection is usually lower, which helps to reduce the overall cost. At the same time, since disassembly and reinstallation are relatively simple, the time and cost of repairing and replacing parts are also reduced.
[0043] Further, in some embodiments, the stylus pen 100 further includes a first connector 900, and the circuit board 400 is electrically connected to the other end of the battery 300 through the first connector 900. Specifically, one end of the first connector 900 can be electrically connected to one end of the battery 300, and the other end of the first connector 900 can be electrically connected to the circuit board 400. Among them, by setting the first connector 900, it is convenient to arrange the circuit board 400 in the storage cavity 210. If the first connector 900 is not set, the battery 300 needs to be directly in contact with the circuit board 400, which will cause the circuit board 400 to be unable to be placed flat in the storage cavity 210.
[0044] For further information, please refer to Figure 2 In some embodiments, the stylus pen 100 further includes a bracket 700, which is disposed in the storage cavity 210, and the bracket 700 is fixedly connected to the housing 200, and the circuit board 400 is connected and fixed to the bracket 700. The bracket 700 is provided with a mounting hole 720, and the first connector 900 includes a first portion 910, a second portion 920, and a third portion 930, wherein both ends of the first portion 910 are respectively connected to the second portion 920 and the third portion 930, and the second portion 920 and the third portion 930 protrude relative to the first portion 910 in the same direction, the second portion 920 is welded to the circuit board 400, the third portion 930 is disposed in the mounting hole 720, and the first portion 910 is electrically connected to one end of the battery 300. Specifically, the shape of the first connector 900 may be a "[" shape, wherein the arrangement of the third portion 930 being inserted into the mounting hole 720 can facilitate the welding of the second portion 920 and the circuit board 400. That is, when the second part 920 and the circuit board 400 are welded, the third part 930 can be inserted into the mounting hole 720 first, thereby fixing the third part 930, and then the second part 920 and the circuit board 400 are welded. On the other hand, after the third part 930 is inserted into the mounting hole 720 and the second board and the circuit board 400 are welded, the first part 910 and the battery 300 can be abutted, so that the first connector 900 can also play the effect of supporting the battery 300.
[0045] In some embodiments, the tail cap 500 is threadedly connected to the housing 200. The specific way in which the tail cap 500 is threadedly connected to the housing 200 can be that threads (internal threads and external threads) are provided on both the tail cap 500 and the housing 200, and the tail cap 500 is sleeved on the housing 200, or the housing 200 is sleeved on the tail cap 500. Threaded connection has the following advantages: threaded connection has the advantage of easy disassembly. This makes it more convenient to repair and replace parts, and improves the maintainability and flexibility of the equipment. Compared with other connection methods, the production cost of threaded connection is usually lower, which helps to reduce the overall cost. At the same time, since disassembly and reinstallation are relatively simple, the time and cost of repairing and replacing parts are also reduced.
[0046] Further, the following describes how the tail cover 500 is electrically connected to the battery 300. Figure 1 and Figure 5 In some embodiments, the stylus pen 100 further includes a second connector 1000. The second connector 1000 is elastic, and the tail cover 500 is provided with a receiving cavity. A portion of the second connector 1000 is provided in the receiving cavity, and another portion of the second connector 1000 protrudes out of the receiving cavity. Specifically, the second connector 1000 may be a spring, and the second connector 1000 is provided in the receiving cavity to realize the electrical connection between the second connector 1000 and the tail cover 500. The second connector 1000 protrudes out of the receiving cavity to facilitate the second connector 1000 to abut against the battery 300, and ensure the stability of the abutment against the battery 300, thereby realizing the electrical connection between the second connector 1000 and the battery 300. In this way, the electrical connection between the tail cover 500 and the battery 300 can be realized by the second connector 1000 abutting against the battery 300.
[0047] Further, in some embodiments, one end of the second connector 1000 is snap-fitted to the cavity wall of the accommodating cavity. Specifically, the specific way in which one end of the second connector 1000 is snap-fitted to the cavity wall of the accommodating cavity may be that a protrusion is provided on the cavity wall of the accommodating cavity, so that the protrusion and the bottom wall of the accommodating cavity form a slot, and the second connector 1000 is snap-fitted into the slot. Among them, the snap-fit method has the following advantages: 1. Quick installation and disassembly. The snap-fit connection is usually achieved by clamping, clamping or pressing, which makes the installation and disassembly process of the second connector 1000 relatively simple and quick. 2. Compact structure. The snap-fit connection usually does not require additional space or materials to fix the components, so a more compact structural design can be achieved, so that the second connector 1000 can be provided on a smaller tail cover 500.
[0048] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
