Detailed Description

Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

As shown in fig. 1-4, an embodiment of the present application provides a touch module, which includes a sensor module 2, a bracket 3, and a stopper 4.

The sensor module 2 can be used to detect touch force information (e.g., the magnitude and position of the touch force). The sensor module 2 may include a circuit board 21 and at least one sensor 22 mounted on the circuit board 21.

The bracket 3 is fixedly connected with the sensor module 2 to support and fix the sensor module 2. Wherein, sensor module 2 can be fixed in one side of support 3, and support 3 is including being located the first spacing face 35 of keeping away from sensor module 2 one side.

The limiting piece 4 passes through the bracket 3 and is connected with the sensor module 2. The limiting member 4 includes a second limiting surface 421 opposite to the first limiting surface 35, the second limiting surface 421 is located on one side of the first limiting surface 35 far away from the sensor module 2, and a gap Ha is formed between the second limiting surface 421 and the first limiting surface 35.

Because the gap Ha is formed between the second limiting surface 421 and the first limiting surface 35, the limiting member 4 does not apply an external force to the sensor module 2 during the normal operation of the touch module, thereby affecting the measurement accuracy of the sensor module 2. Receive at sensor module 2 when making sensor module 2 keep away from the die pull of support 3, sensor module 2 can take place to be out of shape, makes spacing face 421 of second and spacing face 35 can offset spacingly (Ha is 0 this moment), prevents that sensor module 2 from continuing to be out of shape, and then influences sensor module 2's detection. Therefore, the setting of the limiting part 4 ensures that the whole touch module can bear large drawing force load, enhances the drawing force strength borne by the touch module, and further improves the service performance of the touch module.

In some exemplary embodiments, as shown in fig. 1 to 4, the limiting member 4 includes a first limiting member 41 and a second limiting member 42, the first limiting member 41 is fixed on the sensor module 2, the second limiting member 42 is located on a side of the bracket 3 away from the sensor module 2 and connected to the first limiting member 41, and the second limiting surface 421 is disposed on the second limiting member 42.

In the limiting members 4, the first limiting member 41 may be fixed on the circuit board 21 of the sensor module 2, the bracket 3 is provided with a limiting hole 31, and the first limiting member 41 and/or the second limiting member 42 may pass through the limiting hole 31 of the bracket 3, so as to realize connection of the first limiting member 41 and the second limiting member 42. The second limiting surface 421 is disposed on a portion of the second limiting member 42, which is located on a side of the bracket 3 away from the sensor module 2, and the first limiting surface 35 is disposed on a side of the bracket 3 away from the sensor module 2, so that the first limiting surface 35 and the second limiting surface 421 are disposed oppositely. Through clearance fit or counterbalance fit between the first limit surface 35 and the second limit surface 421, the drawing force strength borne by the touch module can be enhanced under the condition of not influencing the measurement precision of the sensor module 2.

The second limiting member 42 can be detachably connected to the first limiting member 41, and the sensor module 2 can be conveniently disassembled and assembled by disassembling and assembling the first limiting member 41 and the second limiting member 42, so that the sensor module 2 can be conveniently maintained and replaced.

In some exemplary embodiments, as shown in fig. 3 to 4, the bracket 3 further includes a third limiting surface 36 located at a side close to the sensor module 2, the first limiting member 41 includes a fourth limiting surface 412 disposed opposite to the third limiting surface 36, and a gap Hb is formed between the third limiting surface 36 and the fourth limiting surface 412.

A gap Hb is formed between the third limiting surface 36 and the fourth limiting surface 412, so that the limiting member 4 does not exert an external force on the sensor module 2 during the normal operation of the touch module, thereby affecting the measurement accuracy of the sensor module 2. When the sensor module 2 is subjected to touch pressing force, the sensor module 2 can deform; after using the overrange dynamics to press, spacing face 36 and the spacing face 412 of fourth can offset spacingly (Hb is 0 at this moment), prevent that sensor module 2 from continuing to warp, protect sensor module 2 not receive the extrusion.

In the touch module, in order to ensure the pull strength without affecting the detection of the touch force signal, the second limiting member 42 cannot contact the bracket 3, and therefore, a gap Ha can be designed between the second limiting surface 421 of the second limiting member 42 and the first limiting surface 35 of the bracket 3; when the drawing force exceeds the threshold value, the sensor module 2 deforms, so that the gap Ha is equal to 0, and at the moment, the second limiting piece 42 starts to act to protect the sensor module 2 from falling off; meanwhile, a gap Hb is designed between the third limiting surface 36 of the bracket 3 and the fourth limiting surface 412 of the first limiting member 41, when the pressing force exceeds a threshold value, the sensor module 2 deforms, so that the gap Hb becomes 0, and at this time, the first limiting member 41 starts to play a limiting role.

Therefore, the first limiting surface 35, the second limiting surface 421, the third limiting surface 36 and the third limiting surface 36 on the limiting member 4 and the bracket 3 are arranged, so that the whole touch module can bear large drawing force load and pressing force load, the drawing force strength and the pressing force strength borne by the touch module are enhanced, and the use performance of the touch module is further improved.

In some exemplary embodiments, as shown in fig. 3 to 4, the first limiting member 41 is a screw post having a threaded hole (i.e., the first threaded hole 413), and the screw post can be welded to the circuit board 21. The outer side wall surface of the screw column is provided with a flange 411, the flange 411 is positioned between the sensor module 2 and the bracket 3, and the fourth limiting surface 412 is arranged on one side of the flange 411, which is adjacent to the bracket 3.

The flange 411 may be annular, an end surface of one side of the annular flange 411, which is adjacent to the bracket 3, forms a fourth limiting surface 412, and the fourth limiting surface 412 may be annular; the end surface of the bracket 3 on the side adjacent to the sensor module 2 (i.e., the end surface on the side adjacent to the annular flange 411) forms the third stopper surface 36, so that the third stopper surface 36 and the fourth stopper surface 412 are disposed opposite to each other with a gap therebetween.

In some exemplary embodiments, as shown in fig. 3-4, the second position-limiting member 42 is a position-limiting screw, which can pass through the position-limiting hole 31 of the bracket 3 and be screwed with the first threaded hole 413 of the screw post.

The head of the limit screw is located on one side of the bracket 3, which is far away from the sensor module 2, the second limit surface 421 is arranged on the head of the limit screw, the end surface of the head of the limit screw, which is close to one side of the bracket 3, forms the second limit surface 421, and the end surface of the bracket 3, which is far away from one side of the sensor module 2 (i.e. the end surface of one side of the head of the limit screw), forms the first limit surface 35, so that the first limit surface 35 and the second limit surface 421 are oppositely arranged and a gap is formed between the two.

Through the cooperation of screw post, stop screw and support 3, can increase the press force degree that the touch module bore and draw the dynamics, prevent that sensor module 2 from warping excessively, taking place to damage because of receiving pressing force or drawing force. In addition, the screw post and the stop screw are convenient to disassemble and assemble, so that the sensor module 2 is convenient to disassemble, and the maintenance, the replacement and the like of the sensor module 2 are realized.

In some exemplary embodiments, the limiting member 4 is provided in two and is close to one side edge of the sensor module 2. As shown in fig. 1, the circuit board 21 of the sensor module 2 is rectangular, and the two position-limiting members 4 are disposed near the long sides of the circuit board 21 and in the middle of the long sides of the circuit board 21 ("the middle" is not strictly the middle point of the long sides of the circuit board 21, but is a portion near the middle).

Of course, the number of the limiting members 4 is not limited to two, and may be another number, and may be disposed at one side edge or multiple side edges of the sensor module 2.

In some exemplary embodiments, as shown in fig. 1, a mounting portion for mounting the feedback motor 10 is provided on the sensor module 2, and the mounting portion is located between the two limiting members 4, that is, the feedback motor 10 mounted on the mounting portion is located between the two limiting members 4. Wherein, two locating parts 4 can be symmetrically arranged on two sides of the installation part.

The feedback motor 10 can vibrate when the sensor module 2 detects the pressing force information to provide a feedback signal, so that the user knows that the pressing force information is detected.

In some exemplary embodiments, the bracket 3 is detachably connected to the sensor module 2.

The support 3 can be dismantled with sensor module 2 and be connected for sensor module 2 can be with the split of support 3, and the first locating part 41 and the second locating part 42 detachably of locating part 4 are connected, make sensor module 2 easy dismounting, conveniently maintain, change sensor module 2.

In some exemplary embodiments, as shown in fig. 8, the touch module further includes an elastic pad 5, one end of the elastic pad 5 is fixedly bonded to the sensor 22 of the sensor module 2, and the other end of the elastic pad is fixedly bonded to the bracket 3, and the bracket 3 is provided with a heat conducting area 37, where the heat conducting area 37 is configured to conduct heat to the bonding glue between the elastic pad 5 and the bracket 3 so as to separate the elastic pad 5 from the bracket 3.

Elastic gasket 5 sets up between sensor 22 and support 3, and elastic gasket 5's both ends bond fixedly with sensor 22 and support 3 respectively to realize the fixed between sensor module 2 and the support 3 through elastic gasket 5. In addition, the limiting piece 4 can assist the elastic gasket 5, so that the whole touch module can bear a large drawing force load.

As shown in fig. 8, the circuit board 21 may be rectangular, four sensors 22 may be disposed at four corners of the rectangular circuit board 21, the four sensors 22 are respectively bonded and fixed to the four elastic gaskets 5, and all the four elastic gaskets 5 are bonded and fixed to the bracket 3.

Four heat conduction areas 37 are arranged on the bracket 3, and the four heat conduction areas 37 are respectively in one-to-one correspondence and contact with the four elastic gaskets 5. The heat conduction area 37 has good heat conduction performance, can reach the bonding glue on the corresponding elastic gasket 5 with the heat, and the bonding glue viscosity after being heated reduces, so the elastic gasket 5 can break away from with the support 3, and then makes the separation of sensor module 2 and support 3 for the dismantlement of sensor module 2 is convenient, and then is convenient for maintain, change sensor module 2.

Wherein, the accessible sets up the blind hole in order to form heat conduction area 37 on support 3, the setting of blind hole for the thickness of heat conduction area 37 department reduces, is favorable to heat transfer to bonding glue.

Wherein, the elastic pad 5 can be a rubber pad and is double-sided back-glued.

The elastic pad 5 has the following three functions:

firstly, the circuit board 21 and the bracket 3 are bonded together;

secondly, buffering the pressing load and protecting the sensor 22;

and thirdly, the vibration of the feedback motor 10 is isolated, so that when the feedback motor 10 is triggered by pressing, vibration energy is concentrated in the touch module and is not transmitted to other parts (such as the shell 9 provided with the touch module), and the pressing touch experience of a user is improved.

The sensor module 2 and the bracket 3 are fixedly bonded through the elastic gasket 5, so that on one hand, the elastic gasket 5 can be smoothly dropped off through heating during maintenance, and the sensor module 2 is respectively disassembled and replaced; on the other hand, the thickness of the whole touch module is smaller, and the requirement of thinning design is met.

In some exemplary embodiments, as shown in fig. 10, the bracket 3 is further provided with a first groove 34, a second groove 33 is provided on a bottom wall of the first groove 34, the sensor module 2 is disposed in the first groove 34, and the elastic pad 5 is disposed in the second groove 33.

The sensor module 2 is in clearance fit with the first groove 34 along a first direction (i.e., a left-right direction in fig. 10), the elastic gasket 5 is in clearance fit with the second groove 33 along the first direction, and a single-side distance S1 between the elastic gasket 5 and an inner side wall surface of the second groove 33 along the first direction is smaller than a single-side distance S2 between the sensor module 2 and the inner side wall surface of the first groove 34 along the first direction.

In the solutions shown in fig. 8 and 9, the total bonding area of the four elastic gaskets 5 is relatively small, and when the finger rubs the touch substrate 1 (e.g., along the left-right direction in fig. 10), the sensor module 2 has a risk of relatively large lateral displacement, and the overall thickness of the touch module is relatively large. Therefore, the sinking type support 3 is designed, a first groove 34 is formed in the support 3, a second groove 33 is formed in the bottom wall of the first groove 34, the elastic gasket 5 is integrally sunk and installed in the second groove 33, and the sensor module 2 is sunk and installed in the first groove 34. Wherein, along first direction, the clearance between the inside wall face of elastic gasket 5 and second recess 33 is S1, and the clearance between the inside wall face of sensor module 2 and first recess 34 is S2, and clearance S1< S2, therefore second recess 33 can play limiting displacement to elastic gasket 5, prevents that elastic gasket 5 from taking place great lateral displacement, and then prevents that sensor module 2 lateral displacement is too big. Meanwhile, the sensor module 2 is sunk into the first groove 34, so that the thickness of the whole touch module can be reduced.

In some exemplary embodiments, the material of the bracket 3 may be steel. Of course, the bracket 3 may be made of other materials. In some exemplary embodiments, the support 3 may be sheet-like or plate-like, such as: the support 3 may be a steel sheet.

In some exemplary embodiments, as shown in fig. 12 and 13, the fixing post, which may be a stud 39, is fixed on the bracket 3, so that the touch module can be locked on the housing 9 of the electronic device by a second fastener (e.g., a screw) through the stud 39.

When the bracket 3 is a steel plate, the steel plate is not bent in a general steel plate design, and in order to rivet and assemble the stud 39 and the steel plate, the steel plate needs to be penetrated at a position corresponding to the stud 39, and a through hole exists at a position on the steel plate where the stud 39 is installed, but the through hole affects the bonding performance of the elastic gasket 5. Therefore, as shown in fig. 12 and 13, a concave bending region 310 is designed on the body of the bracket 3, the bending region 310 can form an adhesive region for adhering and fixing with the elastic pad 5, and the position of the stud 39 is adjusted to be outside the bending region 310. Due to the design of the bending area 310, the bonding area of the bracket 3 is ensured to be flat and free of through holes, and meanwhile, the overall assembling thickness of the touch module is reduced.

In other exemplary embodiments, as shown in fig. 14, the bracket 3 and the fixing column (e.g., the stud 39) may be fixed by laser welding, so that no through hole needs to be formed at the position of the bracket 3 where the stud 39 is fixed, and the bracket 3 and the elastic gasket 5 are fixed by gluing, so that one end of the elastic gasket 5 is fixed to the sensor 22 of the sensor module 2 by gluing, and the other end is fixed to the bracket 3 by gluing.

Since the bracket 3 made of a steel sheet is thin and is easily warped and deformed, in order to prevent the bracket 3 from interfering with other components (such as the upper sensor module 2) after assembly and affecting signals, the bracket 3 is provided with an avoiding concave portion 312. As shown in fig. 14, the bracket 3 is rectangular, and the middle of the long side and the short side of the bracket 3 are designed to be folded inward, so that the bracket 3 is X-shaped as a whole, an avoiding concave part 312 is formed in the middle of the long side and the short side of the bracket 3, protruding fixing parts 311 are formed at four corners of the edge of the bracket 3, and the stud 39 can be fixed on the fixing parts 311. The elastic pad 5 may be bonded to the fixing portion 311 or bonded to another region of the holder 3. The bracket 3 is provided with a central through hole 313 to avoid other components.

The support 3 shown in fig. 14 only needs to ensure that the sticking positions of the sensors 22 at the four corners are flat, and the flatness can be ensured by the pretightening force of the threads after the screws matched with the studs 39 are screwed, so that the rest parts of the support 3 are allowed to be slightly warped and deformed without affecting the performance, and the support 3 can be designed into an ultrathin form. The laser welding process can ensure that no through hole for welding is formed in the support 3, the bonding performance is not affected by the through hole after the elastic gasket 5 is pasted, and the reliability of the touch module is improved, so that the support 3 is ultrathin and has no through hole.

In still other exemplary embodiments, as shown in fig. 1, 5-6, the touch module further includes an elastic pad 5, a pad 6, and a first fastening member 71, wherein one end of the elastic pad 5 is fixedly bonded to the sensor 22 of the sensor module 2, the other end of the elastic pad is fixedly bonded to the pad 6, and the first fastening member 71 passes through the bracket 3 and is detachably connected to the pad 6.

As shown in fig. 6, the bracket 3 may be provided with a fixing hole 32, and the fixing hole 32 may be a countersunk hole; the first fastening member 71 may be a screw, and the cushion block 6 may be opened with a second threaded hole 62, and the first fastening member 71 may pass through the fixing hole 32 of the bracket 3 and be screwed with the second threaded hole 62 of the cushion block 6.

The first end face of the cushion block 6 is bonded with the elastic gasket 5 to provide support for the sensor module 2. The flatness requirement of the first end face of the cushion block 6 is high, and the surface dyne value requirement is high due to the fact that gluing is needed. As shown in fig. 7, an annular rib 63 is disposed on the first end surface of the cushion block 6, and a positioning groove may be formed inside the annular rib 63 for guiding and positioning the assembly with the resilient gasket 5. An annular rib 63 may be provided at the edge of the spacer 6.

As shown in fig. 6, the second end surface of the cushion block 6 may be provided with a boss 61, the second threaded hole 62 may pass through the boss 61, the boss 61 may extend into the fixing hole 32 of the bracket 3, and the first fastening member 71 may be locked and assembled with the cushion block 6.

The cushion block 6 has the following advantages:

firstly, the sensor module 2 and the bracket 3 are fixed through the assembly of the first fastener 71 and the gasket, so that the sensor module 2 is convenient to disassemble, assemble, maintain and replace;

secondly, the touch module is convenient to calibrate as an independent module, and the requirement on calibration equipment is low (if the cushion block 6 is not arranged, the whole electronic equipment comprising the touch module needs to be calibrated, the requirement on corresponding calibration equipment is high, and the production efficiency of the electronic equipment is reduced);

thirdly, the cushion block 6 is an independent part, and a separate design is adopted, so that the parts such as a thin gasket and the like are conveniently added for leveling during assembly, the four sensors 22 are ensured to be positioned on the same horizontal height, and the signal quality is improved.

In some exemplary embodiments, as shown in fig. 8, the bracket 3 is provided with a service hole 38 for servicing the sensor module 2.
