[0044] The cap and electronic pen of the embodiment of the application are described below with reference to the drawings of the specification. It should be noted that the first direction is shown in the up-down direction in the drawings, and the up-down direction can also be regarded as the axial direction of the electronic pen.

[0045] Referring to Figures 1 to 5 , the cap 100 according to the embodiment of the utility model, including main part 110, connecting piece 150 and first buffer 160, main part 110 includes connecting part 120, connecting part 120 is connected to connecting piece 150, connecting piece 150 extends along the first direction, for connecting push rod 200, first buffer 160 is around the circumferential outer side of connecting part 120, first buffer 160 has elasticity, when the cap 100 is applied to the electronic pen and used, when the electronic pen falls and causes the main part 110 to be impacted, the main part 110 can produce radial deflection, thus, the first buffer 160 around the circumferential outer side of the connecting part 120 can buffer the collision when the electronic pen falls, thereby reducing the damage probability.

[0046] The cap 100 can be applied to the electronic pen, for example, referring to Figures 1 to 5The electronic pen provided by the embodiments of the present application comprises a push rod 200, a control board 300, a shell 400 and the pen cap 100 of the above embodiments, the push rod 200 is connected to the side of the connecting piece 150 away from the main body 110, and the push rod 200 is electrically connected to the control board 300. The push rod 200 is at least partially located in the shell 400, the connecting piece 150 on the pen cap 100 is connected to the push rod 200 to achieve installation, and the first buffer 160 is at least partially located in the shell 400. In application, the predetermined operation function can be achieved by using the pen cap 100, for example, some pressing operation can be performed, or some switching function, content erasing and other predetermined operation functions can be achieved by contacting, knocking or rubbing the device end. For example, in some specific applications, the pen cap 100 can be provided with an eraser function, and the erasing operation can be achieved by contacting or knocking or rubbing the device end.

[0047] When the operation is performed through the pen cap 100, the main body 110 of the pen cap 100 may be radially deflected under force, at which time the first buffer 160 can be abutted against the shell 400, the elasticity can be utilized to achieve buffering, reduce rigid collision, reduce the sound that may occur due to the collision between the pen cap 100 and the shell 400 when the operation is performed, achieve mute operation, and thus improve user experience.

[0048] The main body 110 is made of insulating material, and can be hard colloid, plastic or the like. The connecting piece 150 is made of metal material to achieve the operation function of the pen cap 100. The circumferential outer side of the connecting part 120 is the outer surface of the connecting part 120 along the radial direction (with the first direction as the axial direction). The first buffer 160 can be selected as silica gel or other similar elastic body to facilitate preparation and achieve buffering. The first buffer 160 can be assembled on the connecting part 120 after preparation, or can be formed on the connecting part 120 by injection molding.

[0049] Referring to Figures 1 to 3 In some embodiments, the main body 110 further comprises a circumferential wall 140 surrounding the outer circumferential side of the connecting part 120, the circumferential outer side of the connecting part 120 and the circumferential wall 140 are spaced apart to form a limiting groove 130 open in the first direction, and the first buffer 160 is embedded in the limiting groove 130. The limiting groove 130 can improve the connection stability of the first buffer 160 and the main body 110, and limit the radial movement of the first buffer 160 relative to the connecting part 120 by embedding.

[0050] Referring to Figure 1The depth of the limiting groove 130 along the first direction relative to the circumferential wall 140 of the main body 110 is less than the thickness of the first buffer 160 along the first direction, so that the first buffer 160 partially protrudes from the circumferential wall 140, so that the part of the first buffer 160 protruding from the circumferential wall 140 can extend into the shell 400 after the cap 100 is assembled with the shell 400, so that the first buffer 160 and the shell 400 can abut to achieve buffering when the cap 100 is operated to produce radial deflection, thereby achieving noise reduction.

[0051] In some embodiments, the connecting portion 120 is provided with a guide surface 121 away from one end of the main body 110 along the first direction, the guide surface 121 surrounds the outer circumferential side of the connecting piece 150, and the guide surface 121 gradually approaches the outer circumferential side of the connecting piece 150 in the direction away from the main body 110. In application, the guide surface 121 can guide the movement of the connecting piece 150 along the first direction, and reduce the angle of radial deflection of the connecting portion 120. For example, as an example, the shell 400 is provided with a mounting hole on the side facing the cap 100, the push rod 200 is located in the shell 400, the connecting piece 150 is connected to the push rod 200 through the mounting hole, and the connecting portion 120 is located outside the mounting hole. When the cap 100 is operated to move the connecting portion 120 along the first direction towards the mounting hole, thereby driving the push rod 200 to move through the connecting piece 150, the guide surface 121 on the connecting portion 120 can partially extend into the mounting hole. When the cap 100 is impacted or improperly operated to cause the connecting portion 120 to have excessive tendency of radial deflection, the deflection angle can be reduced by abutting the guide surface 121 with the hole wall of the mounting hole.

[0052] Referring to Figures 4 to 6 According to the electronic pen of the embodiment of the utility model, the push rod 200 is connected to the side of the connecting piece 150 away from the main body 110, and the push rod 200 is electrically connected with the control board 300. The inside of the shell 400 can be provided with a containing cavity 430, the control board 300 is contained in the containing cavity 430, at least part of the push rod 200 is contained in the containing cavity 430, the cap 100 covers the containing cavity 430 along the first direction, the side of the containing cavity 430 along the first direction towards the cap 100 has an opening 431, and at least part of the first buffer 160 is located in the opening 431. Therefore, when the main body 110 is forced to produce radial deflection, the first buffer 160 can collide or abut with the shell 400 to achieve elastic buffering, thereby reducing the cracking damage of the shell 400. The shell 400 can include a shell 410 and a pen body 420, the pen body 420 is provided with the containing cavity 430, and the shell 410 surrounds the circumferential outer side of the pen body 420. In application, the first buffer 160 can collide or abut with the pen body 420, or collide or abut with the shell 410, or part of the first buffer 160 collides or abuts with the shell 410, and part of the first buffer 160 collides or abuts with the pen body 420.

[0053] Since the first buffer 160 is an elastic structure, the sound generated by the resistance or collision between the first buffer 160 and the shell 400 due to the operation of the cap 100 is very small under the buffering effect of the first buffer 160, and therefore, the electronic pen using the embodiment of the present application can realize silent operation on the basis of realizing the operation function by using the cap 100, and reduce the probability of damage to the electronic pen.

[0054] The push rod 200 is provided with a receiving / transmitting electrode 170 on the circumferential outer side, and the receiving / transmitting electrode 170 cooperates with the push rod 200 to realize the operation function. The push rod 200 and the control plate 300 can be electrically connected through a metal spring to realize the movement of the cap 100 relative to the shell 400 on the basis of realizing the electrical connection. The push rod 200 and the connecting piece 150 can be stably connected through threaded connection and ensure the conductive contact.

[0055] Referring to Figure 5 In some embodiments, the electronic pen further comprises a bracket 700 arranged in the accommodating cavity 430, and a pressure-sensitive element 510 mounted on the bracket 700, the pressure-sensitive element 510 being electrically connected with the control plate 300, one end of the push rod 200 being connected with the connecting piece 150, and the other end of the push rod 200 comprising an abutting portion 221 facing the pressure-sensitive element 510 and a limiting portion 211 away from the pressure-sensitive element 510, wherein the pressure-sensitive element 510 is located on the side of the abutting portion 221 away from the main body 110, and the main body 110 is driven to move the push rod 200 towards the pressure-sensitive element 510, for example Figure 5 from top to bottom, so that the abutting portion 221 of the push rod 200 presses the pressure-sensitive element 510, realizing the pressure-sensitive function of the cap 100, to further improve the accuracy of the determination of the triggering of the operation function and improve the use experience.

[0056] In some embodiments, the bracket 700 has a limiting surface 710 spaced apart from the limiting portion 211 in the first direction, and the limiting portion 211 and the limiting surface 710 have a first gap 720 in the moving direction of the push rod 200, and the main body 110 and the shell 400 have a second gap 180, for example, the peripheral wall 140 of the main body 110 and the end surface of the shell 400 towards the cap 100 have a second gap 180, and the width W2 of the second gap 180 is not less than the width W1 of the first gap 720. When the cap 100 is used for operation, the main body 110 is driven to move the push rod 200 towards the pressure sensing element 510, so the width W2 of the second gap 180 and the width W1 of the first gap 720 gradually decrease, and the width W2 of the second gap 180 is not less than the width W1 of the first gap 720, which can ensure that the main body 110 has sufficient stroke when driven, so that the abutting portion 221 of the push rod 200 can abut against the pressure sensing element 510, and the pressure sensing function of the pressure sensing element 510 on the cap 100 can be realized.

[0057] In some embodiments, the limiting portion 211 of the push rod 200 is used to abut against the limiting surface 710 on the bracket 700, which can limit the limit position of the push rod 200 moving away from the pressure sensing element 510, avoid the distance between the abutting portion 221 and the pressure sensing element 510 being too large, and thus stabilize the pressure sensing function.

[0058] In some embodiments, the difference between the width W2 of the second gap 180 and the width W1 of the first gap 720 satisfies: 0mm≤W2-W1≤0.5mm, for example, W2 and W1 can be equal, and the difference between them is 0, or the difference between W2 and W1 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm or other arbitrary values within the range of 0mm to 0.5mm. The difference between the width of the second gap 180 and the width of the first gap 720 is within the above range, which can realize compact structure layout, and also can ensure that the main body 110 has sufficient stroke when driven.
