[0029] Compared with the prior art, this application has at least the following beneficial effects:

[0030] In the present application, when the locking mechanism locks the scanning component housing, the scanning component housing is first stored in the accommodating groove so that the scanning component housing is in the storage state, and then the locking portion passes through the first clamping hole and is clamped and matched with the second clamping hole, so that the scanning component housing in the storage state is locked on the host housing. When it is necessary to unlock the locking mechanism, since the abutting portion is located in the accommodating gap and abuts against the button, the locking portion is located in the installation cavity and passes through the first clamping hole and is clamped and matched with the second clamping hole, and the connecting portion is connected between the abutting portion and the locking portion and extends from the accommodating gap to the installation cavity, therefore, when the button is pressed, the button can push the abutting portion to drive the locking portion to move in a direction away from the second clamping hole, so that the abutting portion leaves the second clamping hole, and then the locking mechanism releases the lock on the scanning component housing. When the force applied to the button is removed, the reset member can drive the locking portion to reset in a direction close to the second clamping hole. In other words, the reset member can drive the locking portion to move to the locked position, which is conducive to the next locking and unlocking of the locking mechanism. It can be seen that the locking mechanism in the present application adopts a button, a lock member and a reset member to cooperate, which can realize the lock member to move back and forth between the unlocked position and the locked position. It has a simple structure and a small number of components. In addition, compared with the solution in which the locking mechanism adopts a wedge-shaped surface cooperation structure to enable the lock member to switch back and forth between the unlocked position and the locked position, the friction force of the lock member when switching between the locked position and the unlocked position is reduced, thereby avoiding the locking mechanism from being worn out due to large friction during the process of switching back and forth between the locked state and the unlocked state, thereby improving the service life of the locking mechanism.

[0031] In addition, since the abutment portion is arranged in the accommodating gap and abuts against the button, and the locking portion is located in the installation cavity, when the button is pressed, the button can apply a pressing force to the abutment portion, which is then transmitted from the abutment portion to the connecting portion, and the connecting portion drives the locking portion located in the installation cavity to move in a direction away from the second clamping hole, so that the locking portion arranged in the installation cavity can be controlled by controlling the button arranged on the side wall of the host shell to release the lock of the scanning component shell in the storage state. Since the locking component includes an abutment portion, a connecting portion and a locking portion connected in sequence, only one locking component needs to be provided, which can be abutted against the button and located in the installation cavity to pass through the first clamping hole and abut against the second clamping hole, thereby further simplifying the connection structure between the button and the locking component.

[0032] Furthermore, since the space of the host shell is small, the stroke of the button along the pressing direction of the button is short when the button is pressed. In this way, in order for the locking portion to leave the second clamping hole when the button is pressed, the length of the locking portion extending into the second clamping hole cannot be too long, thereby affecting the reliability of the locking mechanism locking the scanning component shell. Based on this, in the present application, an installation cavity is provided, and the locking portion is located in the installation cavity, the abutting portion is located in the accommodating gap and abuts against the button, and the connecting portion extends from the accommodating gap to the installation cavity and is connected to the locking portion. In this way, the locking portion is prevented from occupying the installation space in the accommodating gap, and a larger movable space is provided for the button, thereby extending the pressing stroke of the button, and then the length of the locking portion extending into the second clamping hole can be extended, thereby improving the stability and reliability of the locking mechanism locking the scanning component shell.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] In the present invention, the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "vertical", "horizontal", "lateral", "longitudinal" and the like are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0052] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0053] In addition, 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 the present invention can be understood according to specific circumstances.

[0054] 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.

[0055] As described in the background technology of the present application, in the related art, a locking mechanism is provided on the main body shell, but due to the small internal space of the main body shell, the movement range of the locking member of the locking mechanism is small, resulting in poor locking reliability of the locking mechanism on the scanning component shell.

[0056] In order to solve the technical problems mentioned in the background technology, the present invention provides a foldable electronic device, wherein the bottom plate of the accommodating groove protrudes toward the outer surface of the back plate to form a support seat, and an installation cavity is formed at the position of the support seat. There is an accommodating gap between the side wall of the groove and the side wall of the host shell, and a button is arranged on the side wall of the host shell. The abutment portion of the locking member is located in the accommodating gap, and the locking portion is located in the installation cavity. The connecting portion respectively connects the abutment portion and the locking portion. It can be seen that the installation cavity provides a larger moving space for the movement of the locking portion, thereby improving the locking reliability of the locking mechanism on the scanning component shell.

[0057] The present application is described in detail below through specific embodiments:

[0058] See also Figures 1 to 6 The embodiment of the present application provides a foldable electronic device 100, which includes a host housing 110, a scanning component housing 120 and a locking mechanism 130, wherein the host housing 110 includes a back plate 111, the outer surface of the back plate 111 is inwardly recessed to form a receiving groove 112, the receiving groove 112 has a groove bottom plate 1121 and a groove side wall 1122, the groove bottom plate 1121 protrudes toward the outer surface of the back plate 111 to form a support seat 113, the groove bottom plate 1121 is The inner surface forms an installation cavity 114 at a position corresponding to the support seat 113, and the side wall of the installation cavity 114 is provided with a first clamping hole 115, and a receiving gap 116 is formed between the groove side wall 1122 and the side wall of the host housing 110; the scanning component housing 120 is rotatably connected to the host housing 110, so that the scanning component housing 120 can be flipped between the unfolded state and the stored state, and the scanning component housing 120 is provided with a second clamping hole 121, and the scanning component housing 120 is stored in the stored state. The second clamping hole 121 is in the receiving groove 112, and the position of the second clamping hole 121 corresponds to the position of the first clamping hole 115; the locking mechanism 130 includes a button 131, a locking member 132 and a reset member 133, the button 131 is arranged on the side wall of the host housing 110, the locking member 132 includes an abutting portion 1321, a connecting portion 1322 and a locking portion 1323 connected in sequence, the abutting portion 1321 is located in the receiving gap 116 and abuts against the button 131, and the connecting portion 1322 extends from the receiving gap 116 to the receiving gap 116. In the cavity 114, the locking portion 1323 passes through the first snap-fitting hole 115 and engages with the second snap-fitting hole 121 to lock the scanning component housing 120 in the storage state. The button 131 can press the abutment portion 1321 to drive the locking portion 1323 to move away from the second snap-fitting hole 121, thereby unlocking the scanning component housing in the storage state. The reset member 133 is configured to apply a reset force to the locking portion 1323 to move in a direction close to the second snap-fitting hole 121.

[0059] Among them, the storage state of the above-mentioned scanning component housing 120 refers to the state when the scanning component housing 120 is stacked on the main body housing 110, and the unfolded state refers to the scanning component housing 120 being rotated to extend in the same direction as the main body housing 110. For example, the scanning component housing 120 and the main body housing 110 both have a length direction, and when the scanning component housing 120 is rotated to the overall structure formed by the scanning component housing 120 and the main body housing 110, it extends along the length direction of the main body housing 110 or the scanning component housing 120.

[0060] In addition, the scanning component housing 120 is rotatably connected to the host housing 110 via a shaft, wherein the shaft may be a common cylindrical shaft or a damping shaft. In addition, the foldable electronic device 100 may be a foldable scanning pen, a foldable mobile phone or other electronic device.

[0061] In addition, the outer surface of the back plate 111 refers to the surface of the back plate 111 facing away from the inner space of the host housing 110 , and the inner surface of the back plate 111 refers to the surface of the back plate 111 facing the inner space of the host housing 110 .

[0062] In this embodiment, when the locking mechanism 130 locks the scanning component housing 120, the scanning component housing 120 is first stored in the receiving groove 112, so that the scanning component housing 120 is in the stored state, and then the locking portion 1323 passes through the first clamping hole 115 and is clamped and matched with the second clamping hole 121, so that the scanning component housing 120 in the stored state is locked on the host housing 110. When it is necessary to unlock the locking mechanism 130, since the abutting portion 1321 is located in the receiving gap 116 and abuts against the button 131, the locking portion 1323 is located in the installation cavity 114, passes through the first clamping hole 115 and is clamped with the second clamping hole 121, and the connecting portion 1322 is connected to the abutting portion 1321. 21 and the locking portion 1323 and extends from the accommodating gap 116 to the mounting cavity 114. Therefore, when the button 131 is pressed, the button 131 can push the abutting portion 1321 to drive the locking portion 1323 to move in a direction away from the second clamping hole 121, so that the abutting portion 1321 leaves the second clamping hole 121, and then the locking mechanism 130 releases the lock on the scanning component housing 120. When the force applied to the button 131 is removed, the reset member 133 can drive the locking portion 1323 to reset in a direction close to the second clamping hole 121. In other words, the reset member 133 can drive the locking portion 1323 to move to the locked position, which is beneficial to the next locking and unlocking of the locking mechanism 130. It can be seen that the locking mechanism 130 in this embodiment adopts the button 131, the lock piece 132 and the reset piece 133 to realize the lock piece 132 to move back and forth between the unlocked position and the locked position. The structure is simple and the number of components is small. In addition, compared with the solution in which the locking mechanism 130 adopts a wedge-shaped surface matching structure to enable the lock piece 132 to switch back and forth between the unlocked position and the locked position, the friction force of the lock piece 132 when switching between the locked position and the unlocked position is reduced, thereby avoiding the lock mechanism 130 from being worn out due to large friction during the process of switching back and forth between the locked state and the unlocked state, thereby improving the service life of the locking mechanism 130.

[0063] In addition, since the abutting portion 1321 is disposed in the accommodating gap 116 and abuts against the button 131, and the locking portion 1323 is located in the mounting cavity 114, when the button 131 is pressed, the button 131 applies a pressing force to the abutting portion 1321, and then the abutting portion 1321 transmits the pressing force to the connecting portion 1322, and the connecting portion 1322 drives the locking portion 1323 located in the mounting cavity 114 to move in a direction away from the second clamping hole 121, thereby controlling the button 131 disposed on the side wall of the host housing 110 to move. The locking portion 1323 arranged in the installation cavity 114 is controlled to release the lock of the scanning component housing 120 in the storage state. Since the locking member 132 includes an abutting portion 1321, a connecting portion 1322 and a locking portion 1323 connected in sequence, only one locking member 132 is required, which can be abutted against the button 131 and can be located in the installation cavity 114 to pass through the first clamping hole 115 and abut against the second clamping hole 121, thereby further simplifying the connection structure between the button 131 and the locking member 132.

[0064] Furthermore, since the space of the host housing 110 is narrow, the stroke of the button 131 along the pressing direction of the button 131 is short when the button 131 is pressed. Thus, in order for the locking portion 1323 to leave the second engaging hole 121 when the button 131 is pressed, the length of the locking portion 1323 extending into the second engaging hole 121 cannot be too long, thereby affecting the reliability of the locking mechanism 130 locking the scanning component housing 120. Based on this, in this embodiment, the mounting cavity 114 is provided, and the locking portion 1323 is located in the mounting cavity 114. The abutment portion 1321 is located in the accommodating gap 116 and abuts against the button 131. The connecting portion 1322 extends from the accommodating gap 116 to the installation cavity 114 and is connected to the locking portion 1323. In this way, the locking portion 1323 is prevented from occupying the installation space in the accommodating gap 116, and a larger activity space is provided for the button 131, thereby extending the pressing stroke of the button 131, and further extending the length of the locking portion 1323 extending into the second clamping hole 121, thereby improving the stability and reliability of the locking mechanism 130 locking the scanning component housing 120.

[0065] It should be noted that the reset member 133 may be a spring, a spring sheet, a rubber pad or the like.

[0066] In some possible embodiments, see Figure 7 The side wall of the installation cavity 114 includes a first side wall 1141 and a second side wall 1142 that are oppositely disposed. The first side wall 1141 is disposed relative to the second side wall 1142 and close to the abutting portion 1321 . The first clamping hole 115 is disposed on the first side wall 1141 .

[0067] Since the first side wall 1141 is arranged close to the abutting portion 1321 relative to the second side wall 1142 and the first snap-fitting hole 115 is arranged on the first side wall 1141 , the extension length of the connecting portion 1322 is shortened compared to setting the first snap-fitting hole 115 on the second side wall 1142 , thereby simplifying the structural design of the locking member 132 .

[0068] In some possible embodiments, see Figure 8 and Fig. 9 The locking mechanism 130 also includes a guide member 134, which is arranged in the main body shell 110 and connected to the inner surface of the back plate 111, and a first guide portion 1341 is arranged on the guide member 134; a second guide portion 13211 is arranged on the abutting portion 1321, and the second guide portion 13211 is slidably matched with the first guide portion 1341 to guide the abutting portion 1321 to move in the accommodating gap 116 along the pressing direction of the button 131.

[0069] Therefore, through the sliding cooperation between the first guide portion 1341 and the second guide portion 13211, the abutment portion 1321 can be guided to move in the accommodating gap 116 along the pressing direction of the button 131. In other words, the consistency of the moving path of the abutment portion 1321 in the accommodating gap 116 is ensured, thereby avoiding the abutment portion 1321 from being stuck in the accommodating gap 116 due to the change in the moving path of the abutment portion 1321, thereby improving the smoothness of unlocking the locking mechanism 130.

[0070] Among them, the structures of the first guide portion 1341 and the second guide portion 13211 are not limited. For example, one of the first guide portion 1341 and the second guide portion 13211 is a guide slider, and the other is a guide groove, or in some possible embodiments, the first guide portion 1341 is a guide bar hole, and the length direction of the guide bar hole is parallel to the pressing direction of the button 131, and the second guide portion 13211 is a guide protrusion, and the guide protrusion cooperates with the guide bar hole.

[0071] Since the guide bar hole and the guide protrusion have a simple structure and are easy to process, when the first guide portion 1341 is a guide bar hole and the second guide portion 13211 is a guide protrusion, the consistency of the moving path of the abutment portion 1321 along the pressing direction can be ensured while simplifying the structure of the locking mechanism 130.

[0072] In addition, there is no limitation on the length of the guide bar hole, as long as the moving range of the guide protrusion in the guide bar hole is equal to the moving range of the abutment portion 1321 in the accommodating gap 116 .

[0073] In some possible embodiments, see Figure 7The reset member 133 is disposed between the side wall of the host housing 110 and the groove side wall 1122 , and is used to apply a reset force to the button 131 to pop outward.

[0074] By arranging the reset member 133 between the side wall of the host housing 110 and the groove side wall 1122, the reset force can be directly transmitted to the button 131 through the abutment portion 1321, and the locking portion 1323 is driven to move to the locked position through the connection portion 1322. Compared with the solution of arranging a reset member installation member in the installation cavity 114, the reset installation member is reduced in the installation cavity 114, or the length of the reset member 133 is shortened, thereby simplifying the difficulty of installing the reset member 133.

[0075] In some possible embodiments, see Figure 8 and Fig. 9 The reset member 133 includes a spring; and a limiting portion 1342 is also provided on the guide member 134, and the limiting portion 1342 is located on one radial side of the spring to limit the radial movement of the spring.

[0076] Specifically, the guide member 134 is stacked on the abutting portion 1321 , a limiting portion 1342 is protruded from one side of the guide member 134 toward the abutting portion 1321 , and a spring installation groove 13212 is provided on the abutting portion 1321 .

[0077] Therefore, by providing the limiting portion 1342 , the radial direction of the spring can be limited to prevent the spring from shaking in the radial direction and thus affecting the resetting effect of the resetting member 133 on the button 131 .

[0078] In some possible embodiments, see Fig.10 The reset member 133 includes a spring; a limiting hole 1343 is also provided on the abutting portion 1321, and one end of the spring extends into the limiting hole 1343 to limit the radial movement of the spring.

[0079] Specifically, a limiting hole 1343 is provided on the guide protrusion, and one end of the spring extends into the limiting hole 1343. The limiting hole 1343 can limit the spring in radial direction to improve the stability and reliability of the spring installation.

[0080] In addition, by providing a limiting hole 1343 on the abutment portion 1321 , the structure of the guide member 134 can be simplified, so that the abutment portion 1321 can limit the radial direction of the spring while installing one end of the spring, thereby simplifying the structure of the locking mechanism 130 .

[0081] In some possible embodiments, see Fig. 9 and Fig.11A connecting boss 1324 is also provided on the abutting portion 1321, and the connecting boss 1324 includes a first boss portion 13241 and a second boss portion 13242 which are sequentially connected along the axial direction of the spring. The first boss portion 13241 is connected to the abutting portion 1321, the spring and the first boss portion 13241 are interference fit, and the spring and the second boss portion 13242 are clearance fit.

[0082] Since the spring and the first boss portion 13241 have an interference fit, when the spring is sleeved on the first boss portion 13241, the spring can be fixedly connected to the first boss portion 13241, thereby achieving a fixed connection between the spring and the abutment portion 1321 while simplifying the connection structure between the spring and the abutment portion 1321. In addition, since the spring and the second boss portion 13242 have a clearance fit, the second boss portion 13242 can play a guiding role both when the spring is installed and when the spring is expanded and contracted.

[0083] In some possible embodiments, the reset member 133 includes a plurality of reset members 133, wherein the plurality of reset members 133 are arranged along a direction perpendicular to the pressing direction of the button 131 (i.e., Fig.10 The interval setting is in the direction indicated by the X arrow in the figure.

[0084] The above-mentioned restoring member 133 includes a plurality of restoring members 133, which means two or more than two restoring members 133.

[0085] Therefore, by providing a plurality of reset members 133 , the effect and stability of the reset member 133 on the button 131 can be improved.

[0086] In some possible embodiments, in combination with Figure 5 and Figure 6 The locking portion 1323 is provided with a clamping protrusion 13232, which passes through the first clamping hole 115 and is engaged with the second clamping hole 121. The clamping protrusion 13232 is provided with a guiding inclined surface (i.e. Figure 6 The inclined plane indicated by the dotted arrow A1).

[0087] By providing a guiding bevel on the locking protrusion 13232, during the process of the locking protrusion 13232 passing through the first locking hole 115 and cooperating with the second locking hole 121, on the one hand, the guiding bevel can guide the locking protrusion 13232, and on the other hand, the provision of the guiding bevel can reduce the contact area between the side wall of the locking protrusion 13232 and the first locking hole 115 and the second locking hole 121, thereby reducing the friction force of the locking protrusion 13232 passing through the first locking hole 115 and cooperating with the second locking hole 121, which is beneficial to the unlocking of the locking mechanism 130, and on the other hand, compared with the solution of reducing the circumference of the locking protrusion 13232 to reduce the contact with the first locking hole 115 and the second locking hole 121, the strength of the locking protrusion 13232 is guaranteed, thereby ensuring the stability and reliability of the locking of the locking mechanism 130.

[0088] In some possible embodiments, see Fig.12 A pre-pressing member 135 is provided between the abutting portion 1321 and the button 131 for providing an outward pre-tightening force to the button 131 .

[0089] It is worth noting that the pre-compression member 135 between the abutment portion 1321 and the button 131 is in a compressed state when the button 131 is not pressed. That is to say, the pre-compression member 135 provides an outward pre-tightening force to the button 131. When the button 131 is pressed, the pre-compression member 135 will be further compressed.

[0090] Therefore, by providing a pre-pressed part 135 between the abutment portion 1321 and the button 131, the button 131 can be fixed relative to the host housing 110 when the button 131 is not pressed, and at the same time, the abutment portion 1321 is fixed relative to the host housing 110, thereby avoiding noise caused by shaking of the button 131 or the abutment portion 1321 relative to the host housing 110, thereby improving the user experience.

[0091] The material of the pre-pressed member 135 may be rubber, foam or other materials, and the following mainly takes the foam material as an example for detailed description.

[0092] In some possible embodiments, see Fig.12 The pre-pressed member 135 is a pre-pressed foam; a mounting groove 13212 is provided on the abutting portion 1321 , and a portion of the pre-pressed foam is disposed in the mounting groove 13212 .

[0093] Since foam has the advantages of good elasticity, light weight, easy use, and reliable performance, when the pre-pressed member 135 is pre-pressed foam, it can improve the pre-tightening effect of the button 131 while avoiding excessive increase in the weight of the host housing 110.

[0094] In addition, by providing the mounting groove 13212 on the abutting portion 1321 , the stability and reliability of the installation of the pre-compression foam can be improved.

[0095] In some possible embodiments, see Fig.13 A third guide portion 1143 is provided at the bottom of the installation cavity 114, and a fourth guide portion 13231 is provided on the locking portion 1323. The fourth guide portion 13231 slidably cooperates with the third guide portion 1143 to guide the locking portion 1323 to move in the installation cavity 114 along the pressing direction of the button 131.

[0096] Among them, there are various specific structures of the third guide portion 1143 and the fourth guide portion 13231. For example, the third guide portion 1143 is a groove, and the fourth guide portion 13231 is a protrusion that slides with the groove, or the third guide portion 1143 is a protrusion, and the fourth guide portion 13231 is a groove that slides with the protrusion.

[0097] Therefore, by providing the third guide portion 1143 and the fourth guide portion 13231, the moving path of the locking portion 1323 in the installation cavity 114 can be guided, thereby preventing the locking portion 1323 from getting stuck in the installation cavity 114 due to changes in the moving trajectory.

[0098] In some possible embodiments, the locking member 132 is made of metal or plastic.

[0099] Since metal has high strength and hardness, when the locking component 132 is made of metal, the strength and rigidity of the locking component 132 can be improved.

[0100] In addition, the above-mentioned plastic refers to hard plastic. If the locking component 132 is made of plastic, the weight and manufacturing cost of the locking component 132 itself can be reduced.

[0101] In some possible embodiments, see Fig.14 The host housing 110 further includes a mounting frame 136 disposed in the accommodating gap 116 , and the abutting portion 1321 is disposed on the mounting frame 136 . The strength of the mounting frame 136 is greater than the strength of the back plate 111 .

[0102] Since the abutment portion 1321 is arranged on the mounting frame 136, the strength of the mounting frame 136 is greater than the strength of the back plate 111. Therefore, by arranging the mounting frame 136 in the accommodating gap 116, the strength of the host housing 110 corresponding to the accommodating gap 116 is improved, thereby improving the service life of the host housing 110.

[0103] In addition, the mounting frame 136 may be a metal member, such as stainless steel, alloy steel, etc.

[0104] In some possible embodiments, the mounting frame 136 and the back plate 111 are integrally formed.

[0105] The above-mentioned integral molding of the mounting frame 136 and the back plate 111 refers to that the mounting frame 136 and the back plate 111 are realized by a laminating process.

[0106] By integrally forming the mounting frame 136 and the back plate 111 , the number of components of the host housing 110 can be reduced, thereby reducing the assembly steps of the host housing 110 , and further improving the assembly efficiency of the host housing 110 .

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
