Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a damping structure and a scanning pen. Background Art

[0002] Electronic devices such as scanning pens usually use damping structures to achieve the flipping and hovering functions of the structure. In the related art, due to the unreasonable structural setting of the damping structure, the scanning pen can only maintain the rotated state in the gear state, while in the non-gear state, the scanning pen is difficult to maintain the rotated state, thereby affecting the user's experience of using electronic devices such as scanning pens in different states. Summary of the invention

[0003] The present application discloses a damping structure and a scanning pen, which can improve the user's experience when an electronic device such as a scanning pen is in different states.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] The first aspect of the present application discloses a damping structure, the damping structure comprising:

[0006] An end face cam having a cam end face and a cam rotation axis, wherein the cam end face comprises a plurality of cam protrusions and a plurality of cam grooves alternately arranged around the cam rotation axis, and the top of the cam protrusion is a first plane;

[0007] An end face cam, comprising a cam end face and a cam rotation axis coaxial with the cam rotation axis, the cam end face being arranged opposite to the cam end face, the cam end face comprising a cam protrusion, the cam protrusion being able to extend into the cam groove or abut against the first plane;

[0008] a reset member, the reset member being configured to apply abutment force to the end face concave wheel and / or the end face cam, so that the end face concave wheel and the end face cam abut against each other along the axial direction;

[0009] A rotating shaft is configured to drive one of the end face cam and the end face cam to rotate relative to the other around the cam rotation axis.

[0010] In a possible structure, the plurality of cam grooves include a first groove and a second groove, and the first groove and the second groove are symmetrical about the center of the cam rotation axis.

[0011] In a possible structure, the cam protrusion includes a plurality of cam protrusions, the plurality of cam protrusions are arranged at intervals around the cam rotation axis, and the positions of the plurality of cam protrusions and the plurality of cam grooves correspond one-to-one.

[0012] In a possible structure, the cam end surface further includes a plurality of cam grooves corresponding one-to-one to the plurality of cam protrusions, and the bottom of the cam groove is a second plane, and the second plane corresponds to the position of the first plane.

[0013] In a possible structure, along the circumference of the end face concave wheel, two sides of the concave wheel groove have inclined groove walls.

[0014] In a possible structure, along the circumference of the end face cam, both sides of the cam protrusion have inclined side walls.

[0015] In a possible structure, the end face cam is provided with a first rotating shaft hole coaxial with the rotating axis of the cam, and the end face cam is provided with a second rotating shaft hole coaxial with the rotating axis of the cam;

[0016] The rotating shaft is inserted into the first rotating shaft hole and the second rotating shaft hole, and the rotating shaft can drive the end face cam to rotate relative to the end face cam wheel around the cam wheel rotation axis.

[0017] Along the axial direction of the rotating shaft, the rotating shaft has a first limiting portion and a second limiting portion arranged at intervals, the end face concave wheel and the end face cam are both located between the first limiting portion and the second limiting portion, the reset member is arranged between the second limiting portion and the end face cam, and the side surface of the end face concave wheel facing away from the end face of the concave wheel abuts against the first limiting portion.

[0018] In a possible structure, the first rotating shaft hole is a round hole, the second rotating shaft hole is a flat hole, the rotating shaft has a flat position, and the flat position matches the flat hole.

[0019] A second aspect of the present application provides a scanning pen, the scanning pen comprising:

[0020] The damping structure according to any one of the first aspects;

[0021] a host connected to one of the end surface cam and the end surface concave wheel; and

[0022] a scanning assembly connected to the other of the end surface cam and the end surface concave wheel;

[0023] When the end face concave wheel and the end face cam rotate relatively, the scanning component can rotate between a storage state and an expanded state relative to the host, and the friction force between the end face concave wheel and the end face cam applies a damping force to the scanning component.

[0024] In a possible structure, the scanning pen further includes a locking structure, and the locking structure is arranged between the host and the scanning component;

[0025] The concave wheel groove has a groove bottom and an inclined groove wall;

[0026] In the storage state, the cam protrusion abuts against the inclined groove wall of the cam groove, and the cam protrusion has a tendency to move toward the groove bottom of the cam groove to apply a retaining force to the scanning component to rotate away from the main machine, and the scanning component is locked to the main machine by the locking structure.

[0027] In one possible structure, the scanning assembly also has a support state;

[0028] When the locking structure is unlocked, the scanning component pops out to the bracket state under the action of the retaining force rotating away from the main unit, so that the scanning component and the main unit maintain a preset angle, and in the bracket state, the cam protrusion abuts against the bottom of the concave wheel groove.

[0029] Compared with the prior art, the beneficial effects of this application are:

[0030] In the application, since the cam end face and the cam wheel end face are arranged opposite to each other, the reset member is configured to apply abutment force to the end face cam wheel and / or the end face cam so that the end face cam wheel and the end face cam abut each other along the axial direction. Therefore, in the process of the rotating shaft driving one of the end face cam wheel and the end face cam to rotate relative to the other around the cam wheel rotation axis, when the cam protrusion leaves a cam wheel groove matched with it, one of the end face cam and the end face cam wheel moves relative to the other in a direction away from each other, and the reset member can be compressed and accumulate potential energy. In this process, the abutment force between the end face cam and the end face cam wheel is increased, and when the cam protrusion leaves the cam wheel groove matched with it, When the cam protrusion abuts against the top of the cam wheel protrusion, since the top of the cam wheel protrusion is the first plane, on the one hand, when the cam protrusion abuts against the top of the cam wheel protrusion, the deformation of the reset member reaches the maximum, so that the abutting force between the cam protrusion and the first plane reaches the maximum, thereby increasing the sliding friction between the cam protrusion and the first plane, and on the other hand, the abutting area between the first plane and the cam protrusion is large, thereby further ensuring the stability of the abutment between the cam protrusion and the cam wheel protrusion, thereby enabling the cam protrusion to stably abut against the cam wheel protrusion when the end face cam is disengaged from the end face cam.

[0031] In addition, compared with the related art, in which the end face cam and the end face concave wheel can be stably abutted against each other only when the cam protrusion and the concave wheel groove are matched, in the present application, the concave wheel protrusion is made into a first plane, that is, the contact area between the concave wheel protrusion and the cam protrusion is increased, thereby improving the stability of the abutment between the concave wheel protrusion and the cam protrusion, that is to say, improving the stability of the abutment between the end face cam and the end face concave wheel when they are out of match. Therefore, when the damping structure is applied to the scanning pen, the scanning assembly can maintain the rotated state in the non-gear state, thereby improving the user experience when the electronic device such as the scanning pen is in different states.

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not 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 this application.

[0050] In this application, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0052] An electronic device such as a foldable scanning pen includes a main body, a scanning component and a damping structure for rotatably connecting the main body and the scanning component. When the scanning component rotates relative to the main body, the damping structure can enable the scanning pen to be stored or unfolded.

[0053] In the prior art, the damping structure includes an end face concave wheel, an end face cam and a reset member. The end face concave wheel and the end face cam can cooperate with each other, and the reset member can provide an abutment force for the end face concave wheel and the end face cam to approach each other. When the scanning component rotates relative to the main body, the end face concave wheel and the end face cam can cooperate with each other or disengage. However, when the end face concave wheel is disengaged from the end face cam (the scanning pen is in a non-gear state), it is difficult to make the end face concave wheel and the end face cam stably abut against each other, thereby affecting the user's experience of using electronic devices such as scanning pens in different states.

[0054] Based on this, the top of the cam protrusion on the end face cam of a damping structure provided in this embodiment is a first plane. In this way, when the cam protrusion on the end face cam abuts against the first plane, it can enable an electronic device such as a scanning pen to maintain a rotated state. As a result, it can enable an electronic device such as a scanning pen to maintain a rotated state when it is not in a gear state, thereby improving the user experience of the scanning pen in different states.

[0055] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0056] See also Figures 1 to 6The embodiment of the present application provides a damping structure 100. The damping structure 100 provided in the embodiment is applied to a foldable scanning pen 200. Optionally, the scanning pen 200 includes a main body 210, a scanning component 220, and a damping structure 100 for rotatably connecting the main body 210 and the scanning component 220. The damping structure 100 can make the scanning component 220 be in a storage state or an unfolded state. The damping structure 100 includes an end face concave wheel 110, an end face cam 120, a reset member 130 and a rotating shaft 140. The end face concave wheel 110 has a concave wheel end face 111 and a concave wheel rotation axis 11a. The concave wheel end face 111 includes a plurality of concave wheel protrusions 1111 and a plurality of concave wheel grooves 1112 alternately arranged around the concave wheel rotation axis 11a. The top of the concave wheel protrusion 1111 is a first plane 1113. The end face cam 120 has a cam end face 121 and a cam rotation axis 12a coaxial with the concave wheel rotation axis. The wheel end face 121 is arranged opposite to the cam end face 111, and the cam end face 121 includes a cam protrusion 1211, which can extend into the cam groove 1112 or abut against the first plane 1113; the reset member 130 is configured to apply an abutting force to the end face cam 110 and / or the end face cam 120 so that the end face cam 110 and the end face cam 120 abut against each other along the axial direction, and the rotating shaft 140 is configured to drive one of the end face cam 110 and the end face cam 120 to rotate relative to the other around the cam rotation axis 11a.

[0057] The above-mentioned multiple refers to a number of two or more than two. The above-mentioned reset element 130 can be a spring, a spring sheet, etc.

[0058] In addition, the rotating shaft 140 is configured to drive one of the end face cam 110 and the end face cam 120 to rotate relative to the other around the cam rotation axis 11a. It should be understood that the rotating shaft 140 can drive the end face cam 110 to rotate relative to the end face cam 120 around the cam rotation axis 11a, or the rotating shaft 140 can drive the end face cam 120 to rotate relative to the end face cam 110 around the cam rotation axis 11a. In addition, the specific structure of the rotating shaft 140 is not limited, and the rotating shaft 140 can be a stepped shaft or a cylindrical shaft.

[0059] In the present embodiment, since the cam end face 121 is arranged opposite to the cam wheel end face 111, the reset member 130 is configured to apply abutting force to the end face cam wheel 110 and / or the end face cam 120 so that the end face cam wheel 110 and the end face cam 120 abut against each other along the axial direction. Therefore, during the process in which the rotating shaft 140 drives one of the end face cam wheel 110 and the end face cam 120 to rotate relative to the other around the cam wheel rotation axis 11a, when the cam protrusion 1211 leaves the cam wheel groove 1112 matched therewith, one of the end face cam wheel 120 and the end face cam wheel 110 moves relative to the other in a direction away from each other, and the reset member 130 can be compressed and accumulate potential energy. In this process, the abutting force between the end face cam wheel 120 and the end face cam wheel 110 is increased. When the cam protrusion 1211 leaves the cam wheel groove 1112 matched therewith, the cam protrusion 1211 abuts against the top of the cam wheel protrusion 1111. The top of the raised portion 1111 is the first plane 1113. Therefore, on the one hand, when the cam raised portion 1211 abuts against the top of the concave wheel raised portion 1111, the deformation of the reset member 130 reaches a maximum, so that the abutting force between the cam raised portion 1211 and the first plane 1113 reaches a maximum, thereby increasing the sliding friction between the cam raised portion 1211 and the first plane 1113. On the other hand, the abutting area between the first plane 1113 and the cam raised portion 1211 is large, thereby further ensuring the stability of the abutment between the cam raised portion 1211 and the concave wheel raised portion 1111. Therefore, when the end face cam 120 disengages from the end face concave wheel 110, the cam raised portion 1211 can be stably abutted against the concave wheel raised portion 1111, that is to say, in the non-gear state, the scanning pen can maintain the rotated state, thereby improving the user experience of electronic devices such as scanning pen in different states.

[0060] In addition, compared with the related art, in which the scanning component 220 can stably abut the end face cam 120 and the end face concave wheel 110 only when the cam protrusion 1211 and the concave wheel groove 1112 cooperate, in the present embodiment, by making the concave wheel protrusion 1111 the first plane 1113, the contact area between the concave wheel protrusion 1111 and the cam protrusion 1211 is increased, thereby improving the stability of the abutment between the concave wheel protrusion 1111 and the cam protrusion 1211, that is, improving the stability of the abutment between the end face cam 120 and the end face concave wheel 110 when they are out of cooperation. Therefore, when the damping structure 100 is applied to the scanning pen 200, the scanning component 220 can maintain a rotation state relative to the host 210 in a non-gear state, thereby improving the user experience when the electronic device such as the scanning pen is in different states.

[0061] It is worth noting that the cooperation between the above-mentioned end face cam 120 and the end face cam wheel 110 refers to the state when the cam protrusion 1211 cooperates with any cam wheel groove 1112. When the cam protrusion 1211 cooperates with different cam wheel grooves 1112, the scanning component 220 can be in different gear states. When the cam protrusion 1211 abuts against the cam wheel protrusion 1111, the scanning component 220 is in a non-gear state.

[0062] In addition, it should be noted that the damping structure 100 in this embodiment can be applied not only to a scanning pen, but also to other electronic devices such as a flip mobile phone, a smart watch, a laptop computer, etc.

[0063] In some possible embodiments, see Figure 4 The plurality of cam grooves 1112 include a first groove 11121 and a second groove 11122 , and the first groove 11121 and the second groove 11122 are symmetrical about the center of the cam rotation axis 11 a .

[0064] Based on the above structure, if the cam protrusion 1211 cooperates with the first groove 11121 in the initial state, if the scanning component 220 is stored in the main unit 210 in the initial state, as one of the end face cam 110 and the end face cam 120 rotates relative to the other around the cam rotation axis 11a, the cam protrusion 1211 leaves the first groove 11121 and abuts against the first plane 1113, as one of the end face cam 110 and the end face cam 120 rotates relative to the other around the cam rotation axis 11a, the cam protrusion 1211 cooperates with the second groove 11122, during this process, the scanning component 220 can rotate 180° relative to the main unit 210, thereby changing the scanning component 220 from the stored state to the unfolded state. It can be seen that since the first groove 11121 and the second groove 11122 are symmetrical about the center of the cam rotation axis 11a, the scanning assembly 220 can be switched between the storage state and the deployed state by rotating one of the end face cam 110 and the end face cam 120 relative to the other around the cam rotation axis 11a.

[0065] Of course, if the scanning component 220 has more different states relative to the host 210, the number of the first grooves 11121 and the second grooves 11122 can be increased.

[0066] In addition, the cam protrusion 1211 may be one or more. Optionally, when the cam protrusion 1211 is one, only one cam protrusion 1211 cooperates with the concave groove 1112 in different gear states of the scanning assembly 220. Optionally, see Figure 4 and Figure 5When the cam protrusion 1211 includes a plurality of cam protrusions 1211, the plurality of cam protrusions 1211 are arranged at intervals around the cam rotation axis 12a, and the positions of the plurality of cam protrusions 1211 and the plurality of cam grooves 1112 correspond one to one.

[0067] Therefore, when one of the end face cam 110 and the end face cam 120 rotates relative to the other around the cam rotation axis 11a, the multiple cam protrusions 1211 will respectively cooperate with the corresponding cam grooves 1112, or the multiple cam protrusions 1211 will abut against the multiple cam protrusions 1111. In this way, the multiple cam protrusions 1211 or the multiple cam protrusions 1111 can be simultaneously subjected to torque and friction, so that the end face cam 120 and the end face cam 110 are subjected to balanced forces during rotation, thereby improving the service life of the damping structure 100.

[0068] In some possible embodiments, see Figure 4 and Figure 5 The cam end surface 121 also includes a plurality of cam grooves 1212 corresponding to the plurality of cam protrusions 1111 , respectively. The bottom of the cam groove 1212 is a second plane 1213 , and the position of the second plane 1213 corresponds to that of the first plane 1113 .

[0069] Since the bottom of the cam groove 1212 is the second plane 1213, and the second plane 1213 corresponds to the first plane 1113, when the cam groove 1212 cooperates with the cam protrusion 1111, the friction area between the end face cam 110 and the end face cam 120 can be increased, thereby improving the stability of the cooperation between the end face cam 120 and the end face cam 110 in this state.

[0070] In some possible embodiments, see Figure 4 , along the circumferential direction of the end face cam 110 (i.e. Figure 4 The cam groove 1112 has inclined groove walls on both sides.

[0071] It is worth noting that the two sides of the cam groove 1112 have inclined groove walls. It should be understood that along the circumference of the end face cam 110 , the distance between the two side walls of the cam groove 1112 decreases along the concave direction of the cam groove 1112 .

[0072] In this embodiment, when one of the end face cam 110 and the end face cam 120 rotates relative to the other about the cam rotation axis 11a and the cam protrusion 1211 leaves the cam groove 1112, the cam protrusion 1211 moves from the groove bottom of the cam groove 1112 to the top of the cam groove 1112. Since the cam groove 1112 has inclined groove walls on both sides of the circumference of the end face cam 110, on the one hand, the inclined groove walls can guide the cam protrusion 1211 so that the cam protrusion 1211 leaves the cam groove 1112, that is, the relative movement of the scanning component 220 is improved. On the one hand, the main body 210 is rotated to adjust different states. On the other hand, when the cam protrusion 1211 abuts against the groove wall of the cam groove 1112, the cam protrusion 1211 has a tendency to move toward the groove bottom of the cam groove 1112, thereby avoiding accidental touching of the scanning component 220 and changing the state of the scanning component 220 relative to the main body 210. On the one hand, when the cam protrusion 1211 leaves the first plane 1113 and enters the cam groove 1112, the inclined groove wall can guide the cam protrusion 1211 so that the cam protrusion 1211 can quickly cooperate with the cam groove 1112.

[0073] In some possible embodiments, see Figure 5 Along the circumferential direction of the end face cam 120 , both sides of the cam protrusion 1211 have inclined side walls.

[0074] Therefore, when the cam protrusion 1211 cooperates with the cam groove 1112 , the contact area between the end face cam 120 and the end face cam 110 can be increased, thereby further improving the stability of the cooperation between the end face cam 120 and the end face cam 110 .

[0075] In addition, the above-mentioned rotating shaft 140 is configured to drive one of the end face cam 110 and the end face cam 120 to rotate relative to the other around the cam rotation axis 11a. It should be understood that the rotating shaft 140 can drive the end face cam 110 to rotate relative to the end face cam 120 around the cam rotation axis 11a, or the rotating shaft 140 can drive the end face cam 120 to rotate relative to the end face cam 110 around the cam rotation axis 11a. The following mainly uses the example of rotating to drive the end face cam 120 to rotate relative to the end face cam 110 around the cam rotation axis 11a.

[0076] In some possible embodiments, see Figure 6 and Figure 7The end face cam 110 is provided with a first shaft hole 112 coaxial with the cam rotation axis 11a, and the end face cam 120 is provided with a second shaft hole 122 coaxial with the cam rotation axis 12a; the shaft 140 is passed through the first shaft hole 112 and the second shaft hole 122, and the shaft 140 can drive the end face cam 120 to rotate relative to the end face cam 110 around the cam rotation axis 11a, and the shaft 140 is along the axial direction (i.e. Figure 6 The rotating shaft 140 has a first limiting portion 141 and a second limiting portion 142 which are arranged at intervals. The end face cam 110 and the end face cam 120 are both located between the first limiting portion 141 and the second limiting portion 142. The reset member 130 is arranged between the second limiting portion 142 and the end face cam 120. The side surface of the end face cam 110 which is away from the cam end face 111 abuts against the first limiting portion.

[0077] Among them, the first limiting portion 141 and the second limiting portion 142 can be a structure integrally formed with the rotating shaft 140, or a structure fixed on the rotating shaft 140, and the specific structure of the first limiting portion 141 and the second limiting portion 142 is not limited. For example, the first limiting portion 141 and the second limiting portion 142 can be annular structures or raised structures.

[0078] Since the end face cam 110 and the end face cam 120 are both located between the first limiting portion 141 and the second limiting portion 142, the reset member 130 is arranged between the second limiting portion 142 and the end face cam 120, and the side surface of the end face cam 110 away from the cam end face 111 abuts against the first limiting portion. Therefore, the first limiting portion is used to limit the axial direction of the end face cam 110 in the rotating shaft 140, and the second limiting portion is used to limit the axial direction of the reset member 130 in the rotating shaft 140. Since the reset member 130 can provide an abutment force for the end face cam 110 and the end face cam 120 to approach each other along the cam rotation axis 11a, the reset member 130 has a pre-pressure between the second limiting portion 142 and the end face cam 120, that is, the reset member 130 is compressed and installed between the second limiting portion 142 and the end face cam 120. While the reset member 130 provides an abutment force for the end face cam 110 and the end face cam 120 to approach each other along the cam rotation axis 11 a , the arrangement structure of the reset member 130 is simplified.

[0079] In addition, there are various structures for realizing that the rotating shaft 140 drives the end cam 120 to rotate relative to the end cam wheel 110 around the cam wheel rotation axis 11a. Figure 6 and Figure 8 The first rotating shaft hole 112 is a round hole, the second rotating shaft hole 122 is a flat hole, and the rotating shaft 140 has a flat position 143, which matches the flat hole.

[0080] Since the first rotating shaft hole 112 is a circular hole, the end face cam 110 is rotationally connected to the rotating shaft 140. Since the second rotating shaft hole 122 is a flat hole, the rotating shaft 140 has a flat position 143. Therefore, when the rotating shaft 140 cooperates with the second rotating shaft hole 122, the flat position 143 and the flat hole can be snap-connected, so that the end face cam 120 is fixed relative to the rotating shaft 140 along the circumference of the rotating shaft 140, so that the rotating shaft 140 drives the end face cam 120 to rotate relative to the end face cam 110, and the end face cam 120 slides relative to the end face cam 110 in the axial direction of the rotating shaft 140.

[0081] Therefore, by making the first rotating shaft hole 112 a round hole, the second rotating shaft hole 122 a flat hole, and providing a flat position 143 on the rotating shaft 140 that cooperates with the flat hole, the structure of the end face cam 110 rotatingly connected relative to the rotating shaft 140 can be simplified, as well as the connection structure of the end face cam 120 fixed circumferentially and axially sliding relative to the rotating shaft 140 can be simplified.

[0082] Of course, the structure for realizing the rotation of the rotating shaft 140 to drive the end face cam 120 relative to the end face concave wheel 110 is not limited to the above structure. For example, a guide protrusion is provided on the second rotating shaft hole 122, and the guide protrusion extends along the axial direction of the rotating shaft 140. A guide groove is provided on the rotating shaft 140, and the length direction of the guide groove is parallel to the axial direction of the rotating shaft 140, and the guide protrusion cooperates with the guide groove.

[0083] See also Fig. 9 The present embodiment further provides a scanning pen 200, which includes a damping structure 100, a main body 210 and a scanning component 220, wherein the damping structure 100 is the damping structure 100 in the above embodiment; the main body 210 is connected to one of the end face cam 120 and the end face concave wheel 110; the scanning component 220 is connected to the other of the end face cam 120 and the end face concave wheel 110; when the end face concave wheel 110 and the end face cam 120 rotate relative to each other, the scanning component 220 can rotate between a storage state and an unfolded state relative to the main body 210, and the friction force between the end face concave wheel 110 and the end face cam 120 applies a damping force to the scanning component 220.

[0084] The scanning pen 200 may have a length direction, a width direction and a thickness direction. Fig. 9As shown, the x direction is used as the length direction of the scanning pen 200, the y direction is used as the width direction of the scanning pen 200, and the z direction is used as the thickness direction of the scanning pen 200. For example, the outline of the scanning pen 200 can be a rectangle, the direction of the long side can be the length direction of the scanning pen 200, and the direction of the short side can be the width direction of the scanning pen 200. Of course, the scanning pen 200 can also be set to a square or an ellipse. The embodiment of the present application does not impose any special restrictions on the specific shape of the scanning pen 200.

[0085] The scanning pen 200 can have a scanning mode of the scanning component 220 to meet the needs of users when scanning for learning. It can also have a video display mode of the display screen to meet the user's demand for using a large screen in a learning scenario. The user can switch the scanning pen 200 to different scenes according to their needs. Of course, in some embodiments, the host 210 may only have the function of playing voice. At this time, the setting of the display screen can also be canceled. The embodiment of the present application does not impose special restrictions on the specific functions of the scanning pen 200.

[0086] In addition, the above-mentioned storage state refers to the state when the scanning component 220 is stacked on the host 210, that is, the angle between the scanning component 220 and the host 210 is 0°, and the unfolded state refers to the angle between the scanning component 220 and the host 210 is 180°.

[0087] Since the scanning pen 200 in this embodiment includes the damping structure 100 in the above embodiment, when the scanning component 220 rotates relative to the host 210, it can still maintain a relatively stable state after the end surface cam 120 and the end surface concave wheel 110 are disengaged, thereby improving the user's experience of using the scanning pen 200 in different states. In addition, the friction between the end surface concave wheel 110 and the end surface cam 120 applies a damping force to the scanning component 220, so that the scanning component 220 can maintain the rotated state after rotating relative to the host 210.

[0088] In some possible embodiments, see Figure 2 and Fig.10 The scanning pen 200 also includes a locking structure 211, which is arranged between the main body 210 and the scanning component 220; the concave groove 1112 has a groove bottom and an inclined groove wall; in the storage state, the cam protrusion 1211 abuts against the inclined groove wall of the concave groove 1112, and the cam protrusion 1211 has a tendency to move toward the groove bottom of the concave groove 1112 to apply a retaining force to the scanning component 220 to rotate away from the main body 210, and the scanning component 220 is locked to the main body 210 through the locking structure 211.

[0089] In this embodiment, since the cam protrusion 1211 abuts against the inclined groove wall of the cam groove 1112 in the storage state, the cam protrusion 1211 has a tendency to move toward the groove bottom of the cam groove 1112. In order to enable the cam protrusion 1211 to stably abut against the inclined side wall of the cam groove 1112, a locking structure 211 is provided. The scanning component 220 is locked to the main machine 210 through the locking structure 211, so as to achieve the purpose of stably abutting the cam protrusion 1211 against the inclined groove wall of the cam groove 1112.

[0090] In some possible embodiments, see Fig.11 , Fig.12 and Fig.13 , the scanning component 220 also has a bracket state; when the locking structure 211 is unlocked, the scanning component 220 pops out to the bracket state under the action of the holding force rotating away from the main body 210, so that the scanning component 220 and the main body 210 maintain a preset angle, and in the bracket state, the cam protrusion 1211 abuts against the bottom of the concave groove 1112.

[0091] When the locking structure 211 is unlocked, the cam protrusion 1211 can slide toward the bottom of the cam groove 1112 under the action of the abutting force of the reset member 130. During this process, the end face cam 120 can rotate at a preset angle (for example, 18°) relative to the end face cam 110, so that the scanning component 220 is at a preset angle relative to the host 210, and the scanning component 220 can trigger other functions in this state, thereby improving the functional diversity of the scanning pen 200.

[0092] For example, a preset angle α (eg, 18°) is maintained between the scanning component 220 and the host 210, so that the scanning component 220 is suspended at the preset angle α, so that the scanning component 220 can be used as a bracket of the host 210 to facilitate the user to watch videos.

[0093] Specifically, the cam groove 1112 includes a first groove 11121 and a second groove 11122 that are symmetrical about the cam rotation axis 11a. Initially (when the scanning assembly 220 is in the storage state), the cam protrusion 1211 abuts against the inclined groove wall of the first groove 11121, and the cam protrusion 1211 has a tendency to move toward the groove bottom of the first groove 11121. At this time, the locking structure 211 locks the end face cam 120 to the end face cam 110. When the locking structure 211 When unlocked, under the action of the reset member 130, the end surface cam 120 can rotate relative to the end surface concave wheel 110 by a preset angle, so that the cam protrusion 1211 cooperates with the first groove 11121. At this time, the scanning component 220 pops out relative to the host 210 at a preset angle (for example, 18°) in a direction away from the host 210. In other words, the scanning component 220 is in a support state and is used as a support. The scanning component 220 is continuously rotated in a direction away from the host 210, so that the scanning component 220 drives the end surface cam 120 to rotate relative to the end surface concave wheel 110 by a first angle (for example, the scanning component 220 rotates from an angle of 18° with the host 210 to an angle of 65° with the host 210), so that the cam protrusion 1211 climbs and leaves the first groove 11121. In other words, the cam protrusion 1211 completes the climbing of the first groove 11121, and the scanning component 220 continues to rotate in a direction away from the host 210. The scanning component 220 is moved to a second angle (for example, the angle between the scanning component 220 and the main body 210 is rotated from 65° to 160°), so that the cam protrusion 1211 and the concave wheel protrusion 1111 have planar friction, and the scanning component 220 continues to rotate in a direction away from the main body 210 until the angle between the scanning component 220 and the main body 210 is 180°, at which time the cam protrusion 1211 abuts against the inclined groove wall of the second groove 11122.
