Abstract
Description
Technical Field
[0001] This application relates to the field of touch assembly device technology, and more particularly to touch assembly devices. Background Technology
[0002] Electronic devices typically include touch controls that can sense user finger movements such as swiping or clicking, and control pointer movement on the display interface. Currently, the stator of touch devices can generate a magnetic field when pressure is detected. The mover is positioned within the magnetic field generated by the stator and vibrates under the influence of the magnetic field, thus providing users with a realistic tactile feedback experience.
[0003] The existing touch assembly device cannot meet the installation accuracy requirements between the stator and mover during assembly, which ultimately affects the vibration performance of the touch device. Utility Model Content
[0004] This application provides a touch assembly device, which can meet the installation accuracy requirements between the stator and the mover by setting a first positioning structure and a second positioning structure.
[0005] In a first aspect, this application provides a touch assembly device, comprising: a base, including a first receiving groove and a second receiving groove, the first receiving groove being used to receive a stator; a first positioning structure disposed within the second receiving groove, the first positioning structure being used to support a mover, the first positioning structure including a positioning protrusion, the two sides of the positioning protrusion being respectively used to abut against the stator and the mover, so that the positioning protrusion is located between the stator and the mover, the positioning protrusion being used to achieve distance positioning between the stator and the mover; and a second positioning structure being used to abut against the mover and cause the mover to abut against the positioning protrusion.
[0006] The touch assembly device provided in this application allows for precise positioning of the stator and mover during assembly using a first positioning structure and a second positioning structure. The stator is positioned within a first receiving groove, the first positioning structure is positioned within a second receiving groove, the mover is positioned on the first positioning structure, and the second positioning structure is positioned on the side of the mover opposite to the positioning protrusion. The two sides of the positioning protrusion abut against the stator and mover, respectively, while the two sides of the mover abut against the positioning protrusion and the second positioning structure, respectively. The second positioning structure fixes the mover between the positioning protrusion and the second positioning structure. The first and second positioning structures work together to achieve accurate installation of the core and mover on the electronic device, ensuring precise spacing between the stator and mover, avoiding distance errors between the stator and mover due to mechanical vibration or assembly errors, and improving the vibration feedback performance of the electronic device.
[0007] In one possible implementation, the first positioning structure includes a main body, the positioning protrusion is located on the side of the main body near the first receiving groove, the touch assembly device includes a first elastic member, the first elastic member is located in the second receiving groove, one end of the first elastic member abuts against the inner wall of the second receiving groove, and the other end of the first elastic member abuts against the side of the main body away from the positioning protrusion, the first elastic member is used to push the positioning protrusion to abut against the stator.
[0008] The first elastic member located between the main body and the inner wall of the second receiving groove is in a compressed state. The first elastic member applies a force toward the stator to the main body, causing the stator to abut against the positioning protrusion. This force is transmitted to the stator through the positioning protrusion, causing the stator to abut against the inner wall of the first receiving groove in the opposite X direction. Thus, after the stator is installed in the first receiving groove, the inner wall of the first receiving groove in the opposite X direction can be used as a reference plane to ensure the accurate installation position of the stator, positioning protrusion, moving part, and second positioning structure on the base. At the same time, the first elastic member applies a force toward the stator to the main body and pushes the main body to move the positioning protrusion, ensuring that the stator always abuts against the positioning protrusion, and the relative position between the stator and the positioning protrusion remains unchanged.
[0009] In one possible implementation, the main body includes a first mounting groove, the opening of which is opposite to the positioning protrusion. One end of the first elastic member abuts against the inner wall of the first mounting groove, and the other end of the first elastic member abuts against the inner wall of the second receiving groove. The first elastic member is used to push the positioning protrusion to abut against the stator.
[0010] A first mounting groove is provided on the main body, and a portion of the first elastic member can be located within the first mounting groove, saving space occupied by the first elastic member. At the same time, the first mounting groove provides mounting space for the first elastic member, allowing the first elastic member to be designed to be longer and provide a larger deformation range under the same compression or tension conditions. This results in applying greater elastic force to the main body, making the contact between the positioning protrusion and the stator more stable, and preventing changes in the position between the positioning protrusion and the stator.
[0011] In one possible implementation, the main body includes a third receiving groove for accommodating the second positioning structure. The main body also includes a first hole structure that penetrates the main body along the thickness direction of the base and communicates with the third receiving groove. The second positioning structure includes a positioning pin that passes through the first hole structure and partially protrudes from it. The portion of the positioning pin protruding from the first hole structure is used to abut against the side of the mover opposite to the positioning protrusion.
[0012] The second positioning structure is housed within the third receiving groove of the main body, which is located within the second receiving groove, and at least a portion of the second positioning structure is also located within the second receiving groove. The main body and the second positioning structure are nested together, eliminating the need for additional space on the base to accommodate the second positioning structure, thus saving space in the touch assembly device. After the second positioning structure is positioned within the third receiving groove, the main body moves towards the stator under the elastic force of the first elastic member. The main body can move the second positioning structure along with it, ensuring that the second positioning structure maintains contact with the mover. A positioning pin passes through the first hole structure, with a portion of the pin protruding from the main body and contacting the side of the mover opposite to the positioning protrusion. The remaining portion of the second positioning structure is embedded within the main body, further optimizing space utilization. The small size of the positioning pin and its protrusion from the main body save space.
[0013] In one possible implementation, the touch assembly device includes a second elastic element, the second positioning structure includes a second mounting groove, the main body includes a second hole structure, the second hole structure and the second mounting groove are arranged along the extending direction of the second elastic element, the second hole structure includes a blind hole, the groove opening of the second mounting groove is opposite to the opening of the second hole structure, one end of the second elastic element abuts against the inner wall of the second mounting groove, the other end of the second elastic element abuts against the inner wall of the second hole structure, and the second elastic element is used to push the second positioning structure to abut against the moving part, so that the moving part abuts against the positioning protrusion.
[0014] The second mounting groove is used to accommodate a portion of the second elastic member. One end of the second elastic member is located inside the second mounting groove and abuts against the inner wall of the second mounting groove. The other end of the second elastic member protrudes from the second mounting groove and extends into the second hole structure, abutting against the inner wall of the second hole structure. The second elastic member is sandwiched between the inner wall of the second mounting groove and the inner wall of the second hole structure. The second elastic member is in a compressed state. The second elastic member applies a spring force towards the stator to the inner wall of the second mounting groove, pushing the second positioning structure to move towards the stator and abut against the mover. This causes the mover to further abut against the side of the positioning protrusion away from the stator. The mover is confined between the positioning protrusion and the second positioning structure, thereby ensuring that the gap between the mover and the stator remains unchanged.
[0015] In one possible implementation, the touch assembly device includes a second elastic member, the second positioning structure includes a second mounting groove, the main body includes a second hole structure, the second hole structure penetrates the main body along the extending direction of the second elastic member, the second hole structure and the second mounting groove are arranged along the extending direction of the second elastic member, the opening of the second mounting groove faces the second hole structure, the second hole structure is used to accommodate a fixing member and is fixedly connected to the fixing member, one end of the second elastic member abuts against the inner wall of the second mounting groove, the other end of the second elastic member is located in the second hole structure and abuts against the fixing member, and the second elastic member is used to push the second positioning structure to abut against the moving part, so that the moving part abuts against the positioning protrusion.
[0016] The fastener is used to fix the position of the other end of the second elastic member, allowing the second elastic member to be clamped between the inner wall of the second mounting groove and the fastener, and to be in a compressed state. The second elastic member applies a spring force towards the stator to the inner wall of the second mounting groove, pushing the second positioning structure towards the stator and abutting against the mover, so that the mover further abuts against the side of the positioning protrusion away from the stator. The mover is confined between the positioning protrusion and the second positioning structure, thereby ensuring that the gap between the mover and the stator remains unchanged. The second hole structure is a through hole, and the fastener can be fixed at any position within the second hole structure. The installation position within the second hole structure can be selected according to the size of the second elastic member, improving assembly flexibility.
[0017] In one possible implementation, the diameter of the first hole structure is larger than the diameter of the locating pin along the extension direction of the second elastic member. The larger diameter of the first hole structure allows the locating pin to move relative to the first hole structure along the extension direction of the second elastic member, thereby reducing the impact of mechanical tolerances or assembly errors during mover installation. It also allows for the installation of different sized movers. Simultaneously, the larger diameter makes it easier for the locating pin to pass through the first hole structure for installation.
[0018] In one possible implementation, the main body is provided with two limiting parts, which are arranged opposite to each other and are used to clamp the mover. Both ends of the mover abut against the two limiting parts, which limit the mover and prevent it from moving relative to the main body, thereby ensuring that the relative position between the mover and the stator remains unchanged.
[0019] In one possible implementation, a fourth receiving groove is provided on the main body. This fourth receiving groove is located on the side of the main body opposite to the bottom wall of the second receiving groove. The fourth receiving groove is used to fix a magnetic structure, which connects the mover and the main body. The fourth receiving groove is used to fix the magnetic structure, the mover is magnetic, and the magnetic structure connects the mover and the main body. The magnetic structure can attract the mover, fixing it to the main body and preventing changes in the relative position between the mover and the main body, further maintaining positional stability between the mover and the stator.
[0020] In one possible implementation, the main body is stepped, comprising a first stepped portion and a second stepped portion, which are stacked along the thickness direction of the base. The first stepped portion has a positioning protrusion on its side near the first receiving groove, and is used to support the moving part. This stepped structure saves space, allowing for the rational arrangement of more components within a limited space and improving space utilization. Since the main body is stepped, the second receiving groove is also designed to be stepped to match the shape of the main body. After the main body is placed in the second receiving groove, the second stepped portion is shielded by the top wall of the second receiving groove, thereby fixing the main body within the second receiving groove.

[0045] This application provides a touch assembly device 10, which can be applied to the assembly of electronic devices, including but not limited to mobile phones, tablets, laptops, touch-screen TVs, wearable devices, virtual reality devices, car steering wheels, and other touch-enabled terminal electronic devices. The touch device of the electronic device includes a stator 20 and a mover 30. When a user clicks the touch device, the stator 20 generates a magnetic field, and the mover 30, located within the magnetic field, vibrates under the influence of the magnetic field, thus providing vibration feedback to the user. The touch assembly device 10 can accurately assemble the stator 20 and the mover 30 into the electronic device, ensuring precise spacing between them, enabling better vibration feedback and a better user experience. (See also...) Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the touch assembly device 10 includes a base 100, a first positioning structure 200, and a second positioning structure 300. The base 100 includes a first receiving groove 110 and a second receiving groove 120, which are arranged along the X direction. The first receiving groove 110 is used to receive the stator 20.
[0046] Continue reading Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the first positioning structure 200 is disposed within the second receiving groove 120. The mover 30 is located on the first positioning structure 200 and on one side of the first positioning structure 200 in the positive Z direction. The first positioning structure 200 is used to support the mover 30. The first positioning structure 200 includes a positioning protrusion 210. The two sides of the positioning protrusion 210 are respectively used to abut against the stator 20 and the mover 30, so that the positioning protrusion 210 is located between the stator 20 and the mover 30. The positioning protrusion 210 is used to achieve distance positioning between the stator 20 and the mover 30. The stator 20 and the mover 30 are positioned and spaced apart by the positioning protrusion 210 during assembly.
[0047] In one embodiment, the stator 20 includes a coil 201 and an iron core 202. The coil 201 is wound around the iron core 202 and is located together with the iron core 202 within a first receiving groove 110. The coil 201 can be wound around the outside of a portion of the iron core 202, and a portion of the iron core 202 protrudes beyond the coil 201. The portion of the iron core 202 protruding beyond the coil 201 abuts against a positioning protrusion 210. The first positioning structure 200 can support a mover 30. The positioning protrusion 210 is located between the iron core 202 and the mover 30. The mover 30 abuts against the side of the positioning protrusion 210 away from the iron core 202, and both sides of the positioning protrusion 210 abut against the iron core 202 and the mover 30, respectively. The iron core 202 and the mover 30 are positioned and spaced apart by the positioning protrusion 210. The positioning protrusion 210 is located between the iron core 202 and the mover 30. The mover 30 abuts against the side of the positioning protrusion 210 away from the iron core 202. The two sides of the positioning protrusion 210 abut against the iron core 202 and the mover 30 respectively. The positioning protrusion 210 provides a positioning interval between the iron core 202 and the mover 30.
[0048] The second positioning structure 300 is used to abut against the mover 30 and cause the mover to abut against the positioning protrusion. Specifically, the mover 30 is located between the positioning protrusion 210 and the second positioning structure 300. The second positioning structure 300 is located on the side of the mover 30 away from the positioning protrusion 210. The second positioning structure 300 can apply a force toward the stator 20 to the mover 30, thereby fixing the position of the mover 30, preventing the mover 30 from moving, and maintaining the abutment between the mover 30 and the positioning protrusion 210.
[0049] When assembling the stator 20 and the mover 30, the touch assembly device 10 provided in this application can accurately position the stator 20 and the mover 30 using a first positioning structure 200 and a second positioning structure 300. The stator 20 is disposed in a first receiving groove 110, the first positioning structure 200 is disposed in a second receiving groove 120, the mover 30 is located on the first positioning structure 200, and the second positioning structure 300 is located on the side of the mover away from the positioning protrusion 210. The two sides of the positioning protrusion 210 abut against the stator 20 and the mover 30, respectively, and the two sides of the mover 30 abut against the positioning protrusion 210 and the second positioning structure 300, respectively. The second positioning structure 300 fixes the mover 30 between the positioning protrusion 210 and the second positioning structure 300. The first positioning structure 200 and the second positioning structure 300 work together to ensure the accurate installation of the iron core 202 and the mover 30 on the electronic device, ensuring the precise interval between the stator 20 and the mover 30, avoiding distance errors between the stator 20 and the mover 30 caused by mechanical vibration or assembly errors, and improving the vibration feedback performance of the electronic device.
[0050] In one embodiment, the stator 20 includes a coil 201 and an iron core 202, both located within a first receiving groove 110. The coil 201 is wound around the iron core 202, and the coil 201 can be wound around the outer side of a portion of the iron core 202, with a portion of the iron core 202 protruding beyond the coil 201. A positioning protrusion 210 is located between the iron core 202 and the mover 30. The mover 30 abuts against the side of the positioning protrusion 210 opposite to the iron core 202, and both sides of the positioning protrusion 210 abut against the iron core 202 and the mover 30, respectively. The positioning protrusion 210 provides a positioning gap between the iron core 202 and the mover 30. The positioning protrusion 210 separates the mover 30 from the iron core 202, keeping the gap between the mover 30 and the iron core 202 fixed and preventing the distance between the mover 30 and the iron core 202 from being too close or too far, which could affect the vibration feedback performance of the electronic device.
[0051] The number of coils 201 can be one or at least two. Coils 201 can be electrically connected to a circuit. When a user taps the touch device, the circuit transmits current to the coils 201, causing them to generate a magnetic field. The mover 30 is located in this magnetic field and vibrates under its influence, thus providing vibration feedback to the user. The number of movers 30 can also be one or at least two.
[0052] In one embodiment, the stator 20 is made of a permanent magnet, an electromagnet, or a soft magnetic material. Examples include iron-silicon alloys, iron-nickel alloys, iron-aluminum alloys, AlNiCo, and ferrites.
[0053] In one embodiment, the positioning protrusion 210 is a sheet-like structure, and is spaced apart from the first positioning structure 200 and the iron core 202. The thickness of the positioning protrusion 210 is 0.03 mm.
[0054] Of course, in some other embodiments, the positioning protrusion 210 can be a columnar structure, and at least two columnar positioning protrusions 210 are arranged at intervals along the Y direction to form a comb-like structure, and multiple columnar positioning protrusions 210 are disposed between the stator 20 and the mover 30.
[0055] In one embodiment, a first mounting hole 111 is provided at the bottom of the first receiving groove 110. The first mounting hole 111 is a through hole that penetrates the bottom of the first receiving groove 110 along the depth direction. After the stator 20 is housed in the first receiving groove 110 and accurately positioned with the mover 30, when the touch assembly device 10 is vacuumed, the air in the first receiving groove 110 is drawn away through the first mounting hole 111, thereby fixing the stator 20 in the first receiving groove 110.
[0056] In one possible implementation, see [reference] Figure 3 and Figure 5 As shown, the first positioning structure 200 includes a main body 220, and a positioning protrusion 210 located on the side of the main body 220 near the first receiving groove 110. The surface of the positioning protrusion 210 facing the first receiving groove 110 and the surface of the main body 220 facing the first receiving groove 110 are coplanar. The touch assembly device 10 includes a first elastic member 400 located in the second receiving groove 120. One end of the first elastic member 400 abuts against the inner wall of the second receiving groove 120, and the other end of the first elastic member 400 abuts against the side of the main body 220 away from the positioning protrusion 210. The first elastic member 400 is used to push the positioning protrusion 210 to abut against the stator 20.
[0057] The first elastic element 400 may include, but is not limited to, springs and rubber. This application uses a spring as an example for explanation. The first elastic element 400 located between the main body 220 and the inner wall of the second receiving groove 120 is in a compressed state. The first elastic element 400 applies a force toward the stator 20 to the main body 220. The stator 20 abuts against the positioning protrusion 210. The force applied by the first elastic element 400 toward the stator 20 to the main body 220 is transmitted to the stator 20 through the positioning protrusion 210, so that the stator 20 abuts against the inner wall of the first receiving groove 110 in the X-direction. Thus, after the stator 20 is installed in the first receiving groove 110, the inner wall of the first receiving groove 110 in the X-direction can be used as a reference plane to ensure that the installation positions of the stator 20, the positioning protrusion 210, the mover 30 and the second positioning structure 300 on the base 100 are accurate. At the same time, the first elastic element 400 applies a force toward the stator 20 to the main body 220 and pushes the main body 220 to move the positioning protrusion 210, so that the stator 20 always abuts against the positioning protrusion 210 and the relative position between the stator 20 and the positioning protrusion 210 remains unchanged.
[0058] In one possible implementation, see [reference] Figure 6 and Figure 7 As shown, the main body 220 includes a first mounting groove 221, the opening of the first mounting groove 221 is away from the positioning protrusion 210, one end of the first elastic member 400 abuts against the inner wall of the first mounting groove 221, and the other end of the first elastic member 400 abuts against the inner wall of the second receiving groove 120. The first elastic member 400 is used to push the positioning protrusion 210 to abut against the stator 20.
[0059] The first mounting groove 221 is used to accommodate a portion of the first elastic member 400. One end of the first elastic member 400 is located inside the first mounting groove 221 and abuts against the inner wall of the first mounting groove 221. The other end of the first elastic member 400 protrudes from the first mounting groove 221 and abuts against the inner wall of the second receiving groove 120. The first elastic member 400 is sandwiched between the inner wall of the first mounting groove 221 and the inner wall of the second receiving groove 120. The first elastic member 400 is in a compressed state. The relative position of the second receiving groove 120 and the base 100 is fixed. The first elastic member 400 applies a spring force toward the stator 20 to the inner wall of the first mounting groove 221, pushing the main body 220 toward the stator 20. The main body 220 drives the positioning protrusion 210 to move toward the stator 20 and abut against the stator 20, so that the stator 20 and the positioning protrusion 210 always remain in abutment.
[0060] A first mounting groove 221 is provided on the main body 220, and a portion of the first elastic member 400 can be located within the first mounting groove 221, saving space occupied by the first elastic member 400. At the same time, the first mounting groove 221 provides mounting space for the first elastic member 400, allowing the first elastic member 400 to be designed to be longer, providing a larger deformation range under the same compression or tension conditions, thereby applying greater elastic force to the main body 220, making the contact between the positioning protrusion 210 and the stator 20 more stable, and preventing changes in the position between the positioning protrusion 210 and the stator 20.
[0061] In one possible implementation, see [reference] Figure 8 and Figure 9As shown, the main body 220 includes a third receiving groove 222 for accommodating the second positioning structure 300. The second positioning structure 300 is accommodated within the third receiving groove 222 of the main body 220. The main body 220 is located within the second receiving groove 120, and at least a portion of the second positioning structure 300 is also located within the second receiving groove 120. The main body 220 and the second positioning structure 300 are nested together, eliminating the need for additional space on the base 100 to accommodate the second positioning structure 300, thus saving space in the touch assembly device 10. After the second positioning structure 300 is located within the third receiving groove 222, the main body 220 moves towards the stator 20 under the elastic force of the first elastic member 400. The main body 220 can move the second positioning structure 300 together, allowing the second positioning structure 300 to maintain contact with the mover 30.
[0062] See Figure 10 and Figure 11 As shown, the main body 220 includes a first hole structure 223, which penetrates the main body 220 along the thickness direction of the base 100, which is the Z-direction. The first hole structure 223 communicates with the third receiving groove 222. The second positioning structure 300 includes a positioning pin 310, which passes through the first hole structure 223 and partially protrudes from it. The portion of the positioning pin 310 protruding from the first hole structure 223 is used to abut against the side of the mover 30 opposite to the positioning protrusion 210.
[0063] In this embodiment, the positioning pin 310 is located on one side of the second positioning structure 300 in the Z direction. The second positioning structure 300 is housed in the third receiving groove 222. The positioning pin 310 passes through the first hole structure 223. Part of the positioning pin 310 protrudes from the main body 220 through the first hole structure 223 and is used to abut against the side of the mover 30 opposite to the positioning protrusion 210. The remaining part of the second positioning structure 300 is embedded in the main body 220, which further optimizes space utilization. The positioning pin 310 is small in size, and the space occupied can be saved after the positioning pin 310 protrudes from the main body 220.
[0064] In one embodiment, the opening of the third receiving groove 222 faces the bottom wall 121 of the second receiving groove 120, so as to facilitate the installation of the second positioning structure 300 into the third receiving groove 222.
[0065] In one embodiment, there are two positioning pins 310, which are symmetrically arranged with the X direction as the axis of symmetry. There are also two first hole structures 223. The two positioning pins 310 pass through the two first hole structures 223 respectively and abut against the side of the mover 30 away from the positioning protrusion 210.
[0066] In one possible implementation, see [reference] Figure 10 and Figure 12 As shown, the touch assembly device 10 includes a second elastic member 500, a second positioning structure 300 including a second mounting groove 320, and a main body 220 including a second hole structure 224. The second hole structure 224 and the second mounting groove 320 are arranged along the extending direction of the second elastic member 500. The second hole structure 224 includes a blind hole. The groove opening of the second mounting groove 320 is opposite to the opening of the second hole structure 224. One end of the second elastic member 500 abuts against the inner wall of the second mounting groove 320, and the other end of the second elastic member 500 abuts against the inner wall of the second hole structure 224. The second elastic member 500 is used to push the second positioning structure 300 to abut against the mover 30, so that the mover 30 abuts against the positioning protrusion 210.
[0067] The second mounting groove 320 is used to accommodate a portion of the second elastic member 500. One end of the second elastic member 500 is located inside the second mounting groove 320 and abuts against the inner wall of the second mounting groove 320. The other end of the second elastic member 500 protrudes from the second mounting groove 320 and extends into the second hole structure 224, abutting against the inner wall of the second hole structure 224. The second elastic member 500 is sandwiched between the inner wall of the second mounting groove 320 and the inner wall of the second hole structure 224. The second elastic member 500 is in a compressed state. The second elastic member 500 applies a spring force toward the stator 20 to the inner wall of the second mounting groove 320, pushing the second positioning structure 300 toward the stator 20 and abutting against the mover 30. This causes the mover 30 to further abut against the side of the positioning protrusion 210 away from the stator 20. The mover 30 is restricted between the positioning protrusion 210 and the second positioning structure 300, thereby ensuring that the gap between the mover 30 and the stator 20 remains unchanged.
[0068] Understandably, this application does not limit the number of the first elastic element 400 and the second elastic element 500. The number of the first elastic element 400 and the second elastic element 500 can be one, two, or three, etc., and the number of the first elastic element 400 and the second elastic element 500 can be equal or unequal. When the number of the first elastic element 400 and the second elastic element 500 is at least two, the spacing between any two adjacent first elastic elements 400 can be equal, and the spacing between any two adjacent second elastic elements 500 can be equal. The elastic force exerted by the second elastic element 500 on the main body 220 of the first positioning structure 200 in the direction away from the stator 20 is less than the elastic force exerted by the first elastic element 400 on the main body 220 of the first positioning structure 200 in the direction toward the stator 20. Therefore, the second elastic element 500 cannot push the main body 220 of the first positioning structure 200 to move away from the stator 20.
[0069] A second mounting groove 320 is provided on the second positioning structure 300, and a second hole structure 224 is provided on the main body 220. One end of the second elastic member 500 is located in the second mounting groove 320, and the other end is located in the second hole structure 224, saving space occupied by the second elastic member 500. At the same time, the second mounting groove 320 and the second hole structure 224 provide installation space for the second elastic member 500, allowing the second elastic member 500 to be designed to be longer and to provide a larger deformation range under the same compression or tension conditions. This results in a greater elastic force being applied to the second elastic member 500, making the contact between the positioning protrusion 210 and the mover 30 more stable and preventing changes in the position between the positioning protrusion 210 and the mover 30.
[0070] In one possible implementation, see [reference] Figure 10 and Figure 13 As shown, the touch assembly device 10 includes a second elastic member 500, a second positioning structure 300 including a second mounting groove 320, and a main body 220 including a second hole structure 224. The second hole structure 224 extends through the main body 220 along the extending direction of the second elastic member 500. The second hole structure 224 and the second mounting groove 320 are arranged along the extending direction of the second elastic member 500. The opening of the second mounting groove 320 faces the second hole structure 224. The second hole structure 224 is used to accommodate the fixing member 600 and is fixedly connected to the fixing member 600. One end of the second elastic member 500 abuts against the inner wall of the second mounting groove 320, and the other end of the second elastic member 500 is located in the second hole structure 224 and abuts against the fixing member 600. The second elastic member 500 is used to push the second positioning structure 300 to abut against the mover 30, so that the mover 30 abuts against the positioning protrusion 210.
[0071] A fastener 600 is fixed inside the second hole structure 224, and the relative position of the fastener 600 and the second hole structure 224 remains unchanged. A second mounting groove 320 is used to accommodate a portion of the second elastic member 500. One end of the second elastic member 500 is located inside the second mounting groove 320, abutting against the inner wall of the second mounting groove 320. The other end of the second elastic member 500 protrudes from the second mounting groove 320, extending into the second hole structure 224 and abutting against the fastener 600 of the second hole structure 224. The fastener 600 is used to fix the position of the other end of the second elastic member 500, allowing the second elastic member 500 to be clamped in the second mounting groove 224. The inner wall of the groove 320 is between the fixing member 600 and is in a compressed state. The second elastic member 500 applies an elastic force toward the stator 20 to the inner wall of the second mounting groove 320, pushing the second positioning structure 300 toward the stator 20 and abutting against the mover 30, so that the mover 30 further abuts against the side of the positioning protrusion 210 away from the stator 20. The mover 30 is restricted between the positioning protrusion 210 and the second positioning structure 300, thereby ensuring that the gap between the mover 30 and the stator 20 remains unchanged.
[0072] Understandably, the second hole structure 224 is a through hole, and the fastener 600 can be fixed at any position within the second hole structure 224. Furthermore, the installation position within the second hole structure 224 can be selected according to the size of the second elastic member 500, thereby improving the flexibility of assembly.
[0073] A second mounting groove 320 is provided on the second positioning structure 300, and a second hole structure 224 is provided on the main body 220. One end of the second elastic member 500 is located in the second mounting groove 320, and the other end is located in the second hole structure 224, saving space occupied by the second elastic member 500. At the same time, the second mounting groove 320 and the second hole structure 224 provide installation space for the second elastic member 500, allowing the second elastic member 500 to be designed to be longer and to provide a larger deformation range under the same compression or tension conditions. This results in a greater elastic force being applied to the second elastic member 500, making the contact between the positioning protrusion 210 and the mover 30 more stable and preventing changes in the position between the positioning protrusion 210 and the mover 30.
[0074] In one possible implementation, see [reference] Figure 11 As shown, along the extending direction of the second elastic member 500, the diameter of the first hole structure 223 is larger than the diameter of the locating pin 310. After the mover 30 is installed, it is sandwiched between the locating protrusion 210 and the locating pin 310. The larger diameter of the first hole structure 223 allows the locating pin 310 to move relative to the first hole structure 223 along the extending direction of the second elastic member 500, thereby reducing the impact of mechanical tolerances or assembly errors during the installation of the mover 30. It also allows for the adaptation of different sizes of movers 30. Simultaneously, the larger diameter makes it easier for the locating pin 310 to pass through the first hole structure 223 for installation.
[0075] In one possible implementation, see [reference] Figure 5 and Figure 6 As shown, the main body 220 is provided with two limiting portions 225, which are arranged opposite to each other. A mover 30 is sandwiched between the two limiting portions 225. The two limiting portions 225 are used to clamp the mover 30. In this application, the two limiting portions 225 are arranged opposite to each other on the main body 220 along the Y direction. The mover 30 is sandwiched between the two limiting portions 225, with both ends of the mover 30 abutting against the two limiting portions 225 respectively. The two limiting portions 225 limit the mover 30, preventing it from moving relative to the main body 220 in the Y direction, thereby ensuring that the relative position between the mover 30 and the stator 20 remains unchanged. This application does not limit the shape of the limiting portions 225; the two limiting portions 225 can have the same or different shapes.
[0076] In one possible implementation, see [reference] Figure 5 and Figure 14 As shown, a fourth receiving groove 226 is provided on the main body 220. The fourth receiving groove 226 is located on the side of the main body 220 away from the bottom wall 121 of the second receiving groove 120. The fourth receiving groove 226 is located on the side of the main body 220 in the positive Z direction. The mover 30 is located on the main body 220, and the opening of the fourth receiving groove 226 faces the mover 30. The fourth receiving groove 226 is used to fix the magnetic structure 700. The mover 30 is magnetic. The magnetic structure 700 is used to connect the mover 30 and the main body 220. The magnetic structure 700 can attract the mover 30 and fix the mover 30 on the main body 220, preventing changes in the relative position between the mover 30 and the main body 220, and further maintaining the positional stability between the mover 30 and the stator 20.
[0077] In one embodiment, the mover 30 is made of a permanent magnet, an electromagnet, or a soft magnetic material. Examples include iron-silicon alloys, iron-nickel alloys, iron-aluminum alloys, AlNiCo, and ferrites.
[0078] In one possible implementation, see [reference] Figure 15 As shown, the bottom of the fourth receiving groove 226 is provided with a second mounting hole 2261. The second mounting hole 2261 is a through hole that penetrates the bottom of the fourth receiving groove 226 along the depth direction of the fourth receiving groove 226. After the magnetic structure 700 is placed in the fourth receiving groove 226, when the touch assembly device 10 is vacuumed, the air in the fourth receiving groove 226 is drawn away through the second mounting hole 2261, thereby fixing the magnetic structure 700 in the fourth receiving groove 226.
[0079] In one possible implementation, see [reference] Figure 5 , Figure 16 and Figure 17 As shown, the main body 220 is stepped, including a first stepped portion 227 and a second stepped portion 228. The first stepped portion 227 and the second stepped portion 228 are stacked along the thickness direction of the base 100. The first stepped portion 227 is located on the side of the second stepped portion 228 in the positive Z-direction. A positioning protrusion 210 is provided on the side of the first stepped portion 227 near the first receiving groove 110. The first stepped portion 227 is used to support the mover 30 and is supported between the bottom wall 121 of the second receiving groove 120 and the mover 30. The stepped structure design saves space, allowing for the rational arrangement of more components within a limited space and improving space utilization. The second receiving groove 120 is also designed to be stepped, matching the shape of the main body 220. After the main body 220 is placed in the second receiving groove 120, the second stepped portion 228 is shielded by the top wall of the second receiving groove 120, thereby fixing the main body 220 within the second receiving groove 120.
[0080] In one embodiment, see Figure 16 As shown, the bottom wall 121 of the second receiving groove 120 is detachably connected to the side wall of the second receiving groove 120 to make the installation of the first positioning structure 200 more convenient.
