Description

Technical Field

[0001] This application relates to the technical field of electronic products, and particularly to a foldable electronic device. Background Art

[0002] With the development of technology, various foldable electronic devices have become indispensable products in daily life and production. For example, foldable mobile phones, pop-up watches, foldable scanning pens, etc.

[0003] Taking the foldable scanning pen as an example, the foldable scanning pen includes a main body housing and a scanning component housing that are rotatably connected. When the main body housing and the scanning component housing are in the folded state, a locking mechanism is required to lock the main body housing and the scanning component housing so that the scanning component housing is fixed relative to the main body housing. However, the existing locking mechanism generally adopts a wedge surface structure. During the process of switching back and forth between the locked state and the unlocked state, this structure of the locking mechanism will generate a large friction force, thereby affecting the service life of the locking mechanism.

The first connecting portion extends out of the accommodating gap and is movably connected to the locking member.

[0012] In a possible implementation, the rotation axis of the butting portion is perpendicular to the rotation axis of the locking member.

[0013] In a possible implementation, a fixed shaft is provided on the inner surface of the backplane. A first gasket, the butting portion, and a second gasket are sequentially sleeved on the fixed shaft. A plurality of bumps are provided on the surfaces of the first gasket and / or the second gasket facing the butting portion, and the first gasket and the second gasket are circumferentially fixed relative to the fixed shaft.

[0014] In a possible implementation, a pre-tightening gasket is further sleeved on the fixed shaft. The pre-tightening gasket can deform axially along the fixed shaft;

[0015] A fastener is provided on the fixed shaft. The fastener is used to limit the axial degrees of freedom of the first gasket, the butting portion, and the second gasket along the fixed shaft and apply a pre-tightening force to the pre-tightening gasket.

[0016] In a possible implementation, the fixed shaft has a flat portion;

[0017] Both the first gasket and the second gasket have flat holes, and the flat holes are matched with the flat portion.

[0027] One end of the second reset member abuts against the locking member, and the other end extends into the installation hole.

[0028] In a possible implementation, the main body housing further includes a mounting bracket. The mounting bracket is fixed to the inner surface of the back plate. The pushing member is provided on the mounting bracket, and the strength of the mounting bracket is greater than the strength of the main body housing.

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

[0030] Since a first latching hole is provided on the shell, the locking member is rotatably connected to the host shell, and a latching protrusion is provided on the locking member. The latching protrusion can pass through the host shell and engage with the first latching hole. Therefore, when the locking mechanism locks the scanning component shell, the scanning component shell is in a storage state. At this time, when the latching protrusion extends out of the host shell, it can engage with the first latching hole, thereby locking the scanning component shell in the storage state. If the scanning component shell is in a non-storage state, the latching protrusion extends out of the host shell and cannot engage with the first latching hole. Because the pushing member is located between the button and the locking member, the button can press the pushing member in the first direction so that the pushing member pushes the locking member to rotate in the direction away from the first locking hole. Therefore, when the locking mechanism unlocks the scanning component housing, it only needs to press the button in the first direction to push the pushing member to drive the locking protrusion to leave the first locking hole, thereby releasing the lock between the scanning component housing and the host housing. It can be seen that the locking mechanism in the present application realizes locking by the locking protrusion and the first locking hole, and is not achieved by friction. In other words, compared with the solution in which the locking mechanism adopts a wedge-shaped surface matching structure to realize the switching of the locking mechanism between the locked state and the unlocked state, the locking mechanism in the present application does not generate a large friction force during the switching process between the locked state and the unlocked state, thereby reducing the friction force of the locking mechanism during the switching process between the locked state and the unlocked state, thereby avoiding the locking mechanism loss due to large friction during the switching process between the locked state and the unlocked state, thereby improving the service life of the locking mechanism.

Detailed implementation manners

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0048] In the present invention, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "vertical", "horizontal", "lateral", "longitudinal", etc. is based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit that the indicated devices, elements or components must have a specific orientation, or be constructed and operated in a specific orientation.

[0049] Moreover, in addition to being used to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0050] In addition, the terms "installed", "set", "provided with", "connected", "connected to" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral structure; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, or there may be internal communication 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.

[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, the meaning of "a plurality" is two or more.

[0052] As described in the background art of the present application, in the related art, a foldable scanning pen includes a main body housing and a scanning component housing that are rotatably connected. When the main body housing and the scanning component housing are in a folded state, a locking mechanism is required to lock the main body housing and the scanning component housing so that the scanning component housing is fixed relative to the main body housing. However, the existing locking mechanisms generally adopt a wedge surface structure. During the process of switching back and forth between the locked state and the unlocked state, such a locking mechanism will generate a large amount of friction, thereby affecting the service life of the locking mechanism.

[0053] To solve the technical problems mentioned in the background art, the present invention provides a foldable electronic device. The locking part is rotatably connected to the main body housing, and a clamping protrusion is provided on the locking part. When the scanning component housing is in the storage state, the clamping protrusion on the locking part passes through the housing and cooperates with the first clamping hole on the scanning component housing for clamping to achieve the locking of the locking mechanism. When the scanning component housing is in the unfolded state, pressing the button along the first direction, the button can push the pushing member to drive the locking part to rotate away from the first clamping hole to achieve the unlocking of the locking mechanism. When the button is released, the reset member can apply a reset force to the locking part to rotate it closer to the first clamping hole, so that the locking part is reset. It can be seen that when the locking mechanism is locked, the clamping protrusion is driven by the reset member to cooperate with the first clamping hole. When the locking mechanism is unlocked, the clamping protrusion can be separated from the first clamping hole by simply pressing the button, without generating a large amount of friction, thus ensuring the service life of the locking mechanism.

[0054] The following details the present application through specific embodiments:

[0055] See Figures 1 - 4 , an embodiment of the present application provides a foldable electronic device 100. The foldable electronic device 100 includes a main body housing 110, a scanning component housing 120, and a locking mechanism 130. Among them, the scanning component housing 120 is rotatably connected to the main body housing 110 so that the scanning component housing 120 can be flipped between an unfolded state and a storage state. A first clamping hole 121 is provided on the scanning component housing 120; the locking mechanism 130 includes a button 131, a pushing member 132, a locking part 133, and a reset member 134. The button 131 is arranged on the side wall of the main body housing 110. The pushing member 132 and the locking part 133 are arranged inside the main body housing 110. The locking part 133 is rotatably connected to the main body housing 110. A clamping protrusion 1331 is provided on the locking part 133. The clamping protrusion 1331 passes through the main body housing 110 and cooperates with the first clamping hole 121 for clamping to lock the scanning component housing 120 in the storage state. The pushing member 132 is located between the button 131 and the locking part 133. The button 131 can move along the first direction (i.e., Figure 3Press the pushing member 132 in the direction indicated by the X arrow in the figure, so that the pushing member 132 pushes the locking member 133 to rotate away from the first engaging hole 121, thereby unlocking the scanning assembly housing 120 in the storage state. The reset member 134 is configured to apply a reset force to the locking member 133 to rotate it towards the first engaging hole 121.

[0056] Among them, the storage state of the scanning assembly housing 120 refers to the state when the scanning assembly housing 120 is stacked on the main body housing 110, and the unfolded state refers to the state when the scanning assembly housing 120 rotates to extend in the same direction as the main body housing 110. For example, both the scanning assembly housing 120 and the main body housing 110 have a length direction. When the scanning assembly housing 120 rotates until the overall structure formed by the scanning assembly housing 120 and the main body housing 110 extends along the length direction of the main body housing 110 or the scanning assembly housing 120.

[0057] In addition, the scanning assembly housing 120 is rotatably connected to the main body housing 110 through a rotating shaft, and the rotating shaft can be an ordinary cylindrical rotating shaft or a damping shaft. In addition, the foldable electronic device 100 can be a foldable scanning pen, a foldable mobile phone and other electronic devices.

[0058] Since the scanning component housing 120 is provided with a first engaging hole 121, the locking member 133 is rotatably connected to the host housing 110, and a engaging protrusion 1331 is provided on the locking member 133. The engaging protrusion 1331 can pass through the host housing 110 and engage with the first engaging hole 121. Therefore, when the locking mechanism 130 locks the scanning component housing 120, the scanning component housing is in a storage state. At this time, when the engaging protrusion 1331 extends out of the host housing 110, it can engage with the first engaging hole 121, thereby locking the scanning component housing 120 in the storage state. If the scanning component housing 120 is in a non-storage state, the engaging protrusion 1331 extends out of the host housing 110 and cannot engage with the first engaging hole 121. Because the pushing member 132 is located between the button 131 and the locking member 133, the button 131 can press the pushing member 132 along the first direction so that the pushing member 132 pushes the locking member 133 to rotate in the direction away from the first engaging hole 121. Therefore, when the locking mechanism unlocks the scanning component housing 120, it only needs to press the button 131 along the first direction to push the pushing member 132 to drive the engaging protrusion 1331 to leave the first engaging hole 121, thereby releasing the locking between the scanning component housing 120 and the host housing 110. It can be seen that in this embodiment, the locking mechanism 130 realizes locking by engaging the engaging protrusion 1331 with the first engaging hole 121. The locking achieved by the snap-fitting of the hole 121 is not achieved by friction. In other words, compared with the solution in which the locking mechanism adopts a wedge-shaped surface matching structure to realize the switching of the locking mechanism between the locked state and the unlocked state, the locking mechanism 130 in this embodiment does not generate a large friction force during the switching process between the locked state and the unlocked state, thereby reducing the friction force of the locking mechanism 130 during the switching process between the locked state and the unlocked state, thereby avoiding the locking mechanism 130 from being worn out due to the large friction during the switching process between the locked state and the unlocked state, thereby increasing the service life of the locking mechanism 130.

[0059] In addition, by pressing the push member 132 in the first direction through the button 131, the push member 132 can drive the locking member 133 to rotate in a direction away from the first engaging hole 121, so that the engaging protrusion 1331 leaves the first engaging hole 121. On the one hand, the locking member 133 rotates towards the first engaging hole 121 to make the locking mechanism in the locked state and rotates away from the first engaging hole 121 to make the locking mechanism 130 in the unlocked state. Compared with the locking or unlocking achieved by the translation of the locking member 133, the stability of the locking mechanism in the locked state is improved, and the friction during the switching between the locked state and the unlocked state of the locking mechanism is reduced, further improving the service life of the locking mechanism. On the other hand, since the engaging protrusion 1331 and the first engaging hole 121 are in an engaging fit, and the structures of the engaging protrusion 1331 and the first engaging hole 121 are simple, the operation of the locking mechanism 130 to achieve the locked state and the unlocked state and the structure of the locking mechanism 130 are simplified.

[0060] In addition, by providing a reset member 134, after the button 131 is pressed in the first direction and the force applied to the button 131 is removed, the reset member 134 can apply a reset force towards the first engaging hole 121 to the locking member 133, so that the locking member 133 can drive the push member 132 to move the button 131 in a direction opposite to the first direction, thereby resetting the button 131, which is convenient for unlocking the scanning component housing 120 in the storage state next time. It can be seen that by providing the reset member 134, only power needs to be applied to the button 131 when the scanning component housing 120 is unlocked in the storage state, and there is no need to provide an additional structure to make the locking mechanism 130 in the unlocked state change to the locked state, simplifying the structure of the locking mechanism 130.

[0061] Moreover, for the foldable electronic device 100, the space of the main body housing 110 of the foldable scanning pen is narrow. In this embodiment, by providing the push member 132, the shape of the push member 132 can be designed according to different installation spaces, thereby improving the flexibility of the installation of the locking mechanism 130.

[0062] It should be noted that when pressing the button 131, the push member 132 can either rotate relative to the main body housing 110 or move relative to the main body housing 110.

[0063] It should be noted that the reset member 134 can be structures such as a spring, a spring sheet, a rubber pad, etc.

[0064] In some possible embodiments, refer to Figure 4 、 Figure 5 and Figure 6, the main body housing 110 includes a back plate 110a. An accommodation groove 112 is formed by inward depression on the outer surface of the back plate 110a. The accommodation groove 112 is used to accommodate the scanning assembly housing 120 in a stored state. The accommodation groove 112 has a groove bottom plate 1121 and groove side walls 1122. A support seat 1123 is formed by the groove bottom plate 1121 protruding toward the outer surface of the back plate 110a. An installation cavity 1124 is formed on the inner surface of the groove bottom plate 1121 corresponding to the position of the support seat 1123. The locking member 133 is located in the installation cavity 1124. A second clamping hole 111 is provided on the side wall of the installation cavity 1124. When the scanning assembly housing 120 is in the stored state, the positions of the second clamping hole 111 and the first clamping hole 121 correspond to each other. An accommodation gap 113 is formed between the groove side wall 1122 and the side wall of the main body housing 110; the pushing member 132 includes a contact portion 1321 and a first connection portion 1322 that are connected to each other. The contact portion 1321 is located in the accommodation gap 113 and abuts against the button 131. The first connection portion 1322 extends out of the accommodation gap 113 and is movably connected to the locking member 133.

[0065] Wherein, the outer surface of the back plate 110a refers to the surface of the back plate 110a facing away from the internal space of the main body housing 110, and the inner surface of the back plate 110a refers to the surface of the back plate 110a facing the internal space of the main body housing 110.

[0066] In addition, when the scanning assembly housing 120 is in the stored state, the positions of the second clamping hole 111 and the first clamping hole 121 correspond to each other. It should be understood that when the scanning assembly housing 120 is in the stored state, the clamping protrusion 1331 can pass through the second clamping hole 111 and be clamped and matched with the first clamping hole 121.

[0067] Furthermore, the first connection portion 1322 extends out of the accommodation gap 113 and is movably connected to the locking member 133. It should be understood that since the locking member 133 is rotatably connected to the main body housing 110, the position of the clamping protrusion 1331 relative to the first connection portion 1322 will change. In other words, the locking member 133 can rotate and move relative to the first connection portion 1322.

[0068] In this embodiment, by arranging the locking member 133 in the installation cavity 1124, the extra space occupied by the locking member 133 in the main body housing 110 can be reduced, making the setting structure between the locking mechanism 130 and the main body housing 110 more compact.

[0069] In addition, by the abutment portion 1321 being located in the accommodating gap 113 and the first connecting portion 1322 extending out of the accommodating gap 113 and movably connected to the locking member 133, when the button 131 is pressed along a first direction, the button 131 can apply a pressing force to the abutment portion 1321, which is then transmitted from the abutment portion 1321 to the first connecting portion 1322, and the first connecting portion 1322 drives the locking member 133 located in the mounting cavity 1124 to rotate in a direction away from the first clamping hole 121, so that the locking member 133 arranged in the mounting cavity 1124 can be controlled to rotate by controlling the button 131 arranged on the side wall of the main body shell 110 to release the lock of the scanning component shell 120 in the storage state.

[0070] In addition, since the space of the host housing 110 is narrow, the stroke of pressing the button 131 along the first direction is short. In this way, in order for the clamping protrusion 1331 on the locking member 133 to leave the first clamping hole 121 when the button 131 is pressed, the length of the clamping protrusion 1331 extending into the first clamping hole 121 cannot be too long, thereby affecting the stability of the locking mechanism 130 locking the scanning component housing 120. Based on this, in this embodiment, by providing the installation cavity 1124 and making the locking member 133 located in the installation cavity 1124, The abutment portion 1321 is located in the accommodating gap 113 and abuts against the button 131, and the first connecting portion 1322 extends out of the accommodating gap 113 and is movably connected to the locking member 133. In this way, the locking member 133 is prevented from occupying the installation space in the accommodating gap 113, and a larger movable space is provided for the button 131, thereby extending the pressing stroke of the button 131 along the first direction, and then being able to increase the length of the locking protrusion 1331 extending into the first locking hole 121, thereby improving the stability and reliability of the locking mechanism 130 locking the scanning component housing 120.

[0071] In some possible embodiments, see Figure 4 One end of the abutting portion 1321 away from the first connecting portion 1322 is rotatably connected to the host housing 110 .

[0072] Since one end of the abutment portion 1321 away from the first connection portion 1322 is rotatably connected to the main housing 110, when the button 131 is pressed along the first direction, one end of the abutment portion 1321 connected to the first connection portion 1322 rotates around the end of the abutment portion 1321 away from the first connection portion 1322. On the one hand, compared with the solution in which the middle part of the abutment portion 1321 is rotatably connected to the main housing 110, the purpose of saving effort is achieved in the process of releasing the locking mechanism 130. On the other hand, compared with the solution in which the abutment portion 1321 is slidably connected to the main housing 110, the width of the accommodating gap 113 along the first direction is reduced, and at the same time, the friction force of the locking mechanism 130 in the process of switching back and forth between the locked state and the unlocked state is reduced.

[0073] In some possible embodiments, refer to Figure 4 , the rotation axis of the abutting portion 1321 (i.e., the dashed line shown as a1 in Figure 4 ) is perpendicular to the rotation axis of the locking member 133 (i.e., the dashed line shown as a2 in Figure 4 ).

[0074] Specifically, the rotation axis of the abutting portion 1321 is perpendicular to the back plate 110a, and the rotation axis of the locking member 133 is parallel to the groove side wall 1122. Thus, the compactness of the structure of the locking member 133 and the pushing member 132 is improved.

[0075] In addition, the rotation axis of the above-mentioned abutting portion 1321 is perpendicular to the rotation axis of the locking member 133. It should be understood that the included angle formed by the rotation axis of the abutting portion 1321 and the rotation axis of the locking member 133 is 90° or close to 90°.

[0076] In some possible embodiments, refer to Figure 7 , Figure 8 and Figure 9 , a fixed shaft 110a1 is provided on the inner surface of the back plate 110a. A first gasket 141, an abutting portion 1321, and a second gasket 142 are sequentially sleeved on the fixed shaft 110a1. A plurality of bumps 144 are provided on the surfaces of the first gasket 141 and / or the second gasket 142 facing the abutting portion 1321, and the first gasket 141 and the second gasket 142 are circumferentially fixed relative to the fixed shaft 110a1.

[0077] Since the first gasket 141, the abutting portion 1321, and the second gasket 142 are sequentially sleeved on the fixed shaft 110a1 and the first gasket 141 and the second gasket 142 are circumferentially fixed relative to the fixed shaft 110a1, when the abutting portion 1321 rotates around the fixed shaft 110a1, the first gasket 141 and the second gasket 142 will not rotate relative to the fixed shaft 110a1. In addition, since a plurality of bumps 144 are provided on the surfaces of the first gasket 141 and the second gasket 142 facing the abutting portion 1321, the contact areas between the first gasket 141 and the abutting portion 1321 and between the second gasket 142 and the abutting portion 1321 are reduced. Thus, during the rotation of the abutting portion 1321 relative to the fixed shaft 110a1, the frictions between the abutting portion 1321 and the first gasket 141 and between the abutting portion 1321 and the second gasket 142 are reduced.

[0078] In addition, the plurality of bumps 144 refers to two or more bumps 144. Optionally, the plurality of bumps 144 are axially surrounded and spaced apart around the fixed shaft 110a1.

[0079] In some possible embodiments, refer to Figure 7, a preloading gasket 143 is also sleeved on the fixed shaft 110a1, and the preloading gasket 143 can deform axially along the fixed shaft; a fastener is arranged on the fixed shaft 110a1, and the fastener is used to limit the degrees of freedom of the first gasket 141, the abutting portion 1321 and the second gasket 142 along the axial direction of the fixed shaft 110a1 and apply a preloading force to the preloading gasket 143.

[0080] Specifically, the fastener has a connecting end and a limiting end. Among them, the connecting end extends into the fixed shaft 110a1, the diameter of the limiting end is larger than the diameter of the fixed shaft 110a1, and one surface of the limiting end facing the connecting end abuts against the surface of the second gasket 142 to apply a preloading force to the preloading gasket 143.

[0081] In addition, the fastener can be structures such as bolts and screws. The material of the above-mentioned preloading gasket 143 can be foam, rubber, etc. The installation position of the above-mentioned preloading gasket 143 can be various. For example, the preloading gasket 143 is located between the main engine housing 110 and the first gasket 141, between the first gasket 141 and the abutting portion 1321, or between the abutting portion 1321 and the second gasket 142, etc.

[0082] In this embodiment, since the preloading gasket 143 is sleeved on the fixed shaft 110a1, and the fastener is used to limit the degrees of freedom of the first gasket 141, the abutting portion 1321 and the second gasket 142 along the axial direction of the fixed shaft 110a1 and apply a preloading force to the preloading gasket 143, therefore, it is possible to avoid a gap between the first gasket 141 and the main engine housing 110, thereby ensuring the stability of the first gasket 141, the second gasket 142 and the abutting portion 1321 relative to the fixed shaft 110a1 in the axial direction of the fixed shaft 110a1.

[0083] In addition, there are various structures for circumferentially fixing the first gasket 141 and the second gasket 142 relative to the fixed shaft 110a1. In some possible embodiments, refer to Figure 8 and Figure 9 , the fixed shaft 110a1 has a flat portion 110a2; both the first gasket 141 and the second gasket 142 have flat holes 145, and the flat holes 145 are matched with the flat portion 110a2.

[0084] Since the process of setting the flat portion 110a2 on the fixed shaft 110a1 and the flat holes 145 on the first gasket 141 and the second gasket 142 is simple, and the design is simple, therefore, the structure of circumferentially fixedly connecting the first gasket 141 and the second gasket 142 to the fixed shaft 110a1 respectively is simplified.

[0085] In some other possible embodiments, a limiting groove is provided on the fixed shaft 110a1, and limiting bumps are provided on the first gasket 141 and the second gasket 142. The limiting bumps cooperate with the limiting groove, so that the first gasket 141 and the second gasket 142 are circumferentially fixed relative to the fixed shaft 110a1.

[0086] In some possible embodiments, referring to Figure 7 and Figure 9 , a guiding strip-shaped hole 13211 is formed in the abutting portion 1321, and the length direction of the guiding strip-shaped hole 13211 is parallel to the first direction; a limiting post 110a3 is provided on the inner surface of the back plate 110a, and the limiting post 110a3 cooperates with the guiding strip-shaped hole 13211.

[0087] Since the length direction of the guiding strip-shaped hole 13211 on the abutting portion 1321 is parallel to the first direction, and the limiting post 110a3 provided on the inner surface of the back plate 110a cooperates with the guiding strip-shaped hole 13211, when the abutting portion 1321 rotates around the fixed shaft 110a1, the rotation of the abutting portion 1321 is guided by the sliding of the limiting post 110a3 in the guiding strip-shaped hole 13211. At the same time, the rotation range of the abutting portion 1321 is limited by the abutting of the end of the guiding strip-shaped hole 13211 against the limiting post 110a3.

[0088] In some possible embodiments, referring to Figure 10 , the reset member 134 includes a first reset member 1341, and the first reset member 1341 is connected between the abutting portion 1321 and the groove side wall 1122.

[0089] Since the first reset member 1341 is connected between the abutting portion 1321 and the groove side wall 1122, when the button 131 is pressed along the first direction, the first reset member 1341 can be pushed to compress and store potential energy. When the button 131 is released, the first reset member 1341 can push the abutting portion 1321 to push the button 131 in the direction opposite to the first direction to reset the button 131. During this process, the abutting portion 1321 can also pull the locking member 133 to move in the direction of the first latching hole 121 through the first connecting portion 1322 to realize the reset of the locking member 133.

[0090] In addition, the first reset member 1341 can be a telescopic spring, a spring piece, a rubber column, etc.

[0091] In some possible embodiments, referring to Figure 7 , a long hole 13212 is provided at one end of the first connecting portion 1322 away from the abutting portion 1321; a connecting shaft 1332 is provided on the locking member 133, and the connecting shaft 1332 cooperates with the long hole 13212.

[0092] Specifically, an installation protrusion is provided on the side of the side wall of the installation cavity 1124 away from the outer surface of the back plate 110a. A rotation groove is provided on the installation protrusion. One end of the locking member 133 is rotatably connected to the rotation groove, and the other end is provided with a clamping protrusion 1331. A connecting shaft 1332 is provided at the end with the clamping protrusion 1331. With such a setting, the purpose of labor-saving rotation of the locking member 133 can be achieved, which is beneficial to the unlocking operation of the locking mechanism 130.

[0093] Since when the locking member 133 rotates relative to the installation cavity 1124, the connecting shaft 1332 has both a speed of moving in the first direction and a speed of moving perpendicular to the first direction. Therefore, for the compactness of the structural setting, a long hole 13212 is provided on the first connecting portion 1322. In this way, when the locking member 133 rotates relative to the side wall of the installation cavity 1124, the connecting shaft 1332 rotates relative to the long hole 13212 and moves along the long hole 13212 in a direction perpendicular to the first direction.

[0094] Among them, the above-mentioned long hole 13212 can be a strip-shaped hole or a U-shaped hole.

[0095] In some possible embodiments, refer to Figure 11 , the side wall of the installation cavity 1124 includes a first side wall 11241 and a second side wall 11242 which are oppositely arranged. The first side wall 11241 is arranged closer to the abutting portion 1321 than the second side wall 11242, and the second clamping hole 111 is arranged on the first side wall 11241.

[0096] Since the first side wall 11241 is arranged closer to the abutting portion 1321 than the second side wall 11242, and the second clamping hole 111 is arranged on the first side wall 11241, therefore, both the length of the first connecting portion 1322 and the protruding length of the clamping protrusion 1331 can be shortened, thereby simplifying the structure of the pushing member 132.

[0097] In some possible embodiments, refer to Figure 10 , the locking member 133 is rotatably connected to the edge of the first side wall 11241 away from the back plate 110a, and the second clamping hole 111 is arranged near the edge of the back plate 110a; the reset member 134 further includes a second reset member 1342, and the second reset member 1342 is connected between the locking member 133 and the second side wall 11242.

[0098] Since the locking member 133 is rotatably connected to the edge of the first side wall 11241 away from the back plate 110a, and the second clamping hole 111 is arranged near the edge of the back plate 110a, therefore, the purpose of labor-saving can be achieved during the process that the first connecting portion 1322 drives the abutting portion 1321 to rotate in a direction away from the first clamping hole 121 through the connecting shaft 1332, which is beneficial to the convenience of unlocking the locking mechanism 130.

[0099] In addition, by arranging the second reset member 1342 between the locking member 133 and the second side wall 11242, the locking member 133 can be prevented from shaking in the installation cavity 1124, thereby avoiding the problem of generating noise due to resonance.

[0100] In some possible embodiments, referring to Figure 10 and Figure 11 , a reset mounting member 150 is further provided in the installation cavity 1124. An installation hole 151 is formed in the reset mounting member 150, and the installation hole 151 is inclined along the tangential direction of the rotation direction of the locking member 133; one end of the second reset member 1342 abuts against the locking member 133, and the other end extends into the installation hole 151.

[0101] By providing the reset mounting member 150 in the installation cavity 1124, the second reset member 1342 can be installed. In addition, since the locking member 133 is rotatably connected to the side wall of the installation cavity 1124, an installation hole 151 is provided in the reset mounting member 150, and the installation hole 151 is inclined along the tangential direction of the rotation direction of the locking member 133.

[0102] In some possible embodiments, referring to Figure 13 , the main body housing 110 further includes a mounting bracket 160. The mounting bracket 160 is fixed to the inner surface of the back plate 110a. The pushing member 132 is provided on the mounting bracket 160, and the strength of the mounting bracket 160 is greater than that of the main body housing 110.

[0103] Thus, by providing the mounting bracket 160 and arranging the pushing member 132 on the mounting bracket 160, the connection strength between the pushing member and the main body housing 110 can be improved, and the service life of the main body housing 110 is increased.

[0104] In addition, the mounting bracket 160 and the reset mounting member 150 are integrally formed to improve the installation efficiency of the mounting bracket 160 and the reset mounting member 150.

[0105] Optionally, referring to Figure 13 , the mounting bracket 160 includes a main body portion 161 and a limiting portion 162 which are connected to each other. The main body portion 161 is located in the accommodation gap 113. The fixed shaft 110a1 and the limiting post 110a3 are both provided on the main body portion 161. The limiting portion 162 extends out of the accommodation gap 113 and extends towards the second side wall 11242. A limiting convex portion 1621 is provided on the limiting portion 162. The limiting convex portion 1621 is used to limit the moving distance of the first connecting portion 1322 towards the second side wall 11242. Thus, the rotation range of the abutting portion 1321 relative to the fixed shaft 110a1 is further ensured.

[0106] In addition, optionally, the abutting portion 1321 has a plate-like structure. The side wall of the abutting portion 1321 close to the main body housing 110 extends in a direction away from the back plate 110a and bends toward the back plate 110a to form a bent portion 1323, and the bent portion 1323 abuts against the button 131.

[0107] Thus, by bending the abutting portion 1321 to form the bent portion 1323, and the bent portion 1323 abuts against the button 131, the strength of the abutting portion 1321 at the contact with the button 131 is improved, thereby improving the service life of the locking mechanism 130.

[0108] 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 them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
