Mouse encoder is widely used in mice, and has the characteristics of high frequency of use and strong random operation. Therefore, the performance of mouse encoder will directly affect the user experience of the mouse.

[0003] In order to obtain a sense of feedback when the encoder is used, teeth are usually arranged on the outside of the turntable, a torsion spring and a limit elastic member are arranged inside the encoder, the torsion spring is installed in the casing, one end of the limit elastic member rotates in the casing, and one end of the torsion spring abuts against the limit elastic member, so that when the wheel rotates, the limit elastic member is always in contact with each tooth position through the rebound effect of the torsion spring. However, in this way, the torsion spring and the limit elastic member need to be installed separately, and the matching installation is more troublesome and less practical. Utility Model Content

The elastic ring has a through hole, and a plurality of openings are provided on the elastic ring. A V-shaped elastic piece is provided on the side wall of the opening. When the rotor rotates, the V-shaped elastic piece contacts each of the teeth in turn to generate a gear feedback feeling.

In this way, the rotor can be installed by passing through the through hole and the rotor positioning hole, thereby ensuring that the rotor can generate a gear feedback sense when rotating, and the installation of the pressed-type magnetic induction encoder is simpler, effectively improving its practicality.

[0028] The technical solution of the present application is further described in detail below through specific embodiments and in combination with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0029] Example 1

[0030] like Figures 1 to 6As shown, in this embodiment, a pressed-type magnetic induction encoder includes: a housing 100, which is provided with an installation cavity 110, and a rotor positioning hole 111 is provided at the bottom of the installation cavity 110; a hand-feel generating member 700, which is installed in the installation cavity 110 and is provided with a through hole 720; a rotor 200, one end of which passes through the through hole 720 and the rotor positioning hole 111 in sequence and is located outside the housing 100, and is spaced apart from the side walls of the through hole 720 and the side walls of the rotor positioning hole 111, and the other end is rotatably arranged in the installation cavity 110, and a tooth position 222 is arranged on a surface close to the hand-feel generating member 700; the tooth position 222 is arranged in cooperation with the hand-feel generating member 700, so that when the rotor 200 rotates, the hand-feel generating member 700 contacts each tooth position 222 in sequence to generate a gear feedback sense.

[0031] Specifically, the left side of the casing 100 has an installation cavity 110, the rotor 200 includes an assembly rod 210 and a main body 220, the assembly rod 210 includes a driving end 211 and a connecting end 212, the shape of the rotor positioning hole 111 and the shape of the through hole 720 are both adapted to the shape of the driving end 211, and the driving end 211 is positioned through the rotor positioning hole 111, the driving end 211 and the through hole 720 are spaced apart, the cross-sectional shape of the main body 220 is set to be annular, the main body 220 is sleeved and fixed on the connecting end 212, the shape of the installation cavity 110 is adapted to the shape of the main body 220, and the main body 220 is rotatably arranged in the installation cavity 110, and a side of the main body 220 close to the rotor positioning hole 111 is protruding along the direction of the rotor positioning hole 111 and provided with a plurality of tooth positions 222. The hand-feeling component 700 is fixedly clamped at the bottom of the installation cavity 110, and the through hole 720 and the rotor positioning hole 111 are correspondingly arranged. The hand-feeling component 700 is arranged between the rotor positioning hole 111 and the rotor 200, and the side of the hand-feeling component 700 facing away from the rotor positioning hole 111 contacts each tooth position 222 in sequence.

[0032] It is worth noting that the external device drives the rotor 200 to rotate in the installation cavity 110, and positions the rotor 200 through the rotor positioning hole 111, and the rotor 200 is spaced apart from the side wall of the through hole 720. Since the hand-feeling component 700 is fixedly arranged in the housing 100, and one side of the hand-feeling component 700 contacts the rotating rotor 200, one side of the hand-feeling component 700 can generate a force on the rotating tooth position 222, thereby generating a gear feedback sense. In this way, the rotor 200 only needs to be passed through the through hole 720 and the rotor positioning hole 111 for installation, so that while ensuring that the rotor 200 can generate a gear feedback sense when rotating, the installation of the pressed-type magnetic induction encoder 10 is simpler, effectively improving its practicality.

[0033] In order to facilitate the use of the hand feeling generating member 700, as Figures 3 to 6As shown, in one embodiment, the hand feeling generating element 700 includes an elastic ring 710, which is installed in the installation cavity 110. The elastic ring 710 has a through hole 720, and a plurality of openings 730 are opened on the elastic ring 710. A V-shaped elastic piece 740 is arranged on the side wall of the opening 730. When the rotor 200 rotates, the V-shaped elastic piece 740 contacts each tooth position 222 in turn to generate a gear feedback feeling.

[0034] Specifically, the elastic ring 710 is fixedly clamped in the installation cavity 110, a through hole 720 is opened in the middle of the elastic ring 710, a plurality of openings 730 are opened on the circumferential side of the elastic ring 710, and V-shaped elastic pieces 740 are installed on the side walls of the openings 730. Each V-shaped elastic piece 740 is arranged clockwise along the circumferential direction. The cone bottom of the V-shaped elastic piece 740 is arranged away from the rotor positioning hole 111, and the cone bottom of the V-shaped elastic piece 740 contacts each tooth position 222, thereby generating a gear feedback sense.

[0035] In one embodiment, the conical bottom of the V-shaped spring piece 740 is provided with a chamfer, so as to facilitate the shifting.

[0036] In order to facilitate the use of the elastic ring 710, as Figures 3 to 6 As shown, in one embodiment, the number of the openings 730 is set to two, two V-shaped spring pieces 740 are relatively arranged on both sides of the spring ring 710, and one end of the V-shaped spring piece 740 is suspended.

[0037] Specifically, the two V-shaped spring clips 740 are arranged clockwise along the circumferential direction, and the two V-shaped spring clips 740 are respectively arranged on the front and rear sides of the spring ring 710, one end of the V-shaped spring clip 740 is connected to the side wall of the opening 730, and the other end is suspended, so that the other end of the V-shaped spring clip 740 is spaced apart from the side wall of the opening 730, to ensure that the V-shaped spring clip 740 has sufficient elasticity to contact each tooth position 222, so as to fully generate a gear feedback feeling.

[0038] In order to facilitate the fixing and clamping of the elastic ring 710 in the installation cavity 110, as shown in FIG. Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment, at least two positioning posts 113 are disposed on the bottom of the installation cavity 110 , and a positioning hole 750 is formed on the hand feeling generating member 700 , and the positioning posts 113 are installed in the positioning hole 750 .

The shape of the positioning column 113 is adapted to the shape of the positioning hole 750. Through the limiting clamping effect of the positioning column 113 on the side wall of the positioning hole 750, the elastic ring 710 can be fixedly clamped in the installation cavity 110.

[0040] In order to facilitate the production of the elastic ring 710, in one embodiment, the cross-sectional shape of the positioning column 113 is set to be circular, square or triangular.

[0041] Specifically, the shape of the elastic ring 710 is subject to actual production requirements.

[0042] For example, the cross-sectional shape of the positioning post 113 is set to be circular. For another example, the cross-sectional shape of the positioning post 113 is set to be square. For another example, the cross-sectional shape of the positioning post 113 is set to be triangular.

[0043] In order to facilitate the snap ring 710 to be inserted into the positioning column 113, Figure 3 As shown, in one embodiment, the positioning column 113 is provided with a chamfer.

[0044] Specifically, by providing a chamfer on one end of the positioning column 113 away from the rotor positioning hole 111 , it is convenient for the positioning hole 750 to penetrate into the rotor positioning hole 111 , thereby effectively increasing the practicality of the pressed-sheet magnetic induction encoder 10 .

[0045] In order to facilitate the installation of the rotor 200 in the casing 100 and prevent it from being separated from the casing 100 during rotation, as shown in FIG. Figure 3 and Figure 6 As shown, in one embodiment, a retaining member 120 is provided in the casing 100 to prevent the rotor 200 from falling off.

[0046] Specifically, refer to Figure 6 The main body 220 is provided with an outer groove 224 on one side away from the rotor positioning hole 111, so that a step is formed on the outer periphery of the main body 220. The retaining member 120 is installed at one end of the installation cavity 110 away from the rotor positioning hole 111, and the step is engaged with the retaining member 120, so as to prevent the rotor 200 from falling off. The retaining member 120 can be provided with at least two undercuts, for example, four undercuts.

[0047] In order to facilitate the installation of the rotor 200, Figure 3 As shown, in one embodiment, a chamfer is provided on the undercut.

[0048] Specifically, a chamfer is provided at one end of the retaining member 120 away from the rotor positioning hole 111 . Thus, by providing a chamfer at the left end of the undercut, it is possible to ensure that the rotor 200 rotates smoothly to avoid jamming.

[0049] In order to facilitate the use of magnetic induction encoders, such as Figure 2 , Figure 5 and Figure 6As shown, in one embodiment, the pressed-type magnetic induction encoder 10 further includes a magnet 300, a magnetic angle sensor 600, a PCB board 400 and a terminal 500. The magnet 300 is mounted on the rotor 200, the PCB board 400 is mounted on the housing 100 and is spaced apart from the rotor 200 and the magnet 300, the magnetic angle sensor 600 is connected to the PCB board 400, and the terminal 500 is connected to the PCB board 400.

[0050] Specifically, the left side of the casing 100 has an installation cavity 110, and the side wall of the installation cavity 110 is provided with an accommodating groove 112 outwardly, and the shape of the accommodating groove 112 is adapted to the shape of the PCB board 400, so that the PCB board 400 can be installed in the casing 100, and then the casing 100 can protect the PCB board 400. The magnet 300 is fixed on the main body 220. Four terminals 500 are provided, and the four terminals 500 are embedded and welded on the PCB, and the terminals 500 are electrically connected to the PCB board 400, and the four terminals 500 are embedded and clamped on the casing 100. The magnetic angle sensor 600 is welded on the PCB board 400, the magnetic angle sensor 600 is electrically connected to the PCB board 400, and the magnetic angle sensor 600 is arranged in correspondence with the magnet 300. When the external force drives the rotor 200 to rotate, the rotor 200 rotates in the installation cavity 110, and the magnet 300 installed on the rotor 200 rotates accordingly. At this time, the magnetic angle sensor 600 installed on the PCB board 400 can sense the rotation of the magnet 300, that is, the magnetic angle sensor 600 can use the angular phase change of the magnet 300 to excite the internal magnetic sensor, thereby realizing the acquisition and translation of information. Afterwards, the magnetic angle sensor 600 converts the detected magnetic field strain into an mV-level application electrical signal, and outputs it to the application end through the terminal 500 on the PCB board 400.

[0051] In order to facilitate the installation and use of the magnet 300, Figure 2 and Figure 6 As shown, in one embodiment, the magnet 300 is arranged in a ring shape, a magnetic slot 221 is opened on the rotor 200 , and the magnet 300 is installed in the magnetic slot 221 .

[0053] In order to prevent the magnet 300 from being separated from the magnetic slot 221, as Figure 6 As shown, in one embodiment, a locking member for positioning the locking magnet 300 is disposed in the magnetic slot 221 .

[0054] Specifically, the locking member is provided as an anti-skid rib 223. By providing the anti-skid rib 223, after the magnet 300 is installed in the magnetic slot 221, the friction force on the magnet 300 can be increased, thereby effectively preventing the magnet 300 from easily escaping from the magnetic slot 221. Among them, the anti-skid rib 223 can be provided as four to ensure that the magnet 300 is tightly installed in the rotor 200.

[0055] In order to facilitate the assembly of the magnet 300, as Figure 6 As shown, in one embodiment, one end of the anti-slip rib 223 away from the rotor positioning hole 111 is provided with a chamfer.

[0056] Specifically, by chamfering the left end of the anti-slip rib 223 , it is convenient for the magnet 300 to be pressed into the rotor 200 .

[0057] In order to facilitate the installation of the magnet 300, Figure 6 As shown, in one embodiment, a chamfer is provided on the side wall of the magnetic slot 221 close to the connection end 212 .

[0058] Specifically, by rounding the inner side of the magnetic groove 221 , it is easier for the magnet 300 to be assembled into the magnetic groove 221 .

[0059] In order to facilitate the use of the rotor 200, as Figures 2 to 4 As shown, in one embodiment, a mating groove 213 is opened inside the assembly rod 210, and the cross-sectional shape of the mating groove 213 is set to be a hexagon, and the diameter of the mating groove 213 near the connecting end 212 is smaller than the diameter of the mating groove 213 near the driving end 211.

[0060] Specifically, this structure can ensure that the external drive rod is easy to assemble while ensuring that the external drive rod and the assembly rod 210 have high matching accuracy.

[0061] In order to facilitate the installation of the pressed magnetic induction encoder 10 on an external assembly, such as Figure 1 and Figure 3 As shown, in one embodiment, the housing 100 is provided with a connector 130 for tightly fitting with an external assembly.

[0062] Specifically, by providing a connector 130 at the bottom end of the housing, it is convenient to connect the pressed-type magnetic induction encoder 10 to an external assembly. For example, the connector 130 can be provided as two symmetrically arranged protrusions, and the external assembly is an assembly plate, and a small hole matching the protrusion is provided on the assembly plate, and the protrusion is engaged and clamped in the small hole, so that it is convenient to install the pressed-type magnetic induction encoder 10 on the external assembly.
