Description

Technical Field

[0001] This invention relates to the field of beverage making machine technology, specifically to a pin assembly, a body, and a beverage making machine. Background Technology

[0002] The casing of a beverage maker is generally not designed to be completely enclosed. This is because the casing houses at least one functional module, such as a brewing module or a grinding module. To facilitate the disassembly and maintenance of this module, the casing is typically designed to include a main body and a lid. One end of the main body has an opening. The lid is movably mounted at this opening. Current technology generally uses a snap-fit ​​mechanism to lock the opening when it needs to be closed. However, snap-fit ​​mechanisms are prone to accidental activation, allowing the lid to unlock and be easily opened, thus reducing the quality of use. Summary of the Invention

[0022] Furthermore, to achieve the above objectives, the present invention also provides an apparatus comprising: The main unit housing has an internal mounting cavity with an opening. A cover, movably mounted to the main housing, so as to movably open and movably close the opening; and, The latch assembly as described above; In this configuration, one of the main casing and the cover is a first main body, and the other is a second main body. After the cover moves to close the opening, the driving member drives the pin to move to the first position.

The cover also has a second shell wall, and a second mounting hole is provided at the hole of the second shell wall, which communicates with the first mounting hole. The driving component is movably mounted in the second mounting hole.

[0025] Optionally, the wall of the first mounting hole is provided with a rib, and at least three ribs are provided at equal intervals along the circumference of the first mounting hole, and each rib extends elongated along the depth direction of the first mounting hole. The pin is movably inserted through the first mounting hole and movably abuts against each of the protruding ribs.

[0026] Optionally, the driving member includes a first driving segment and a second driving segment connected in sequence, the second driving segment being received in the second mounting hole, and the first driving segment extending out of the second mounting hole; The body also includes a limiting member, which is detachably mounted on the second shell wall to restrict the second drive section from dislodging outward from the second mounting hole.

[0027] In addition, to achieve the above objectives, the present invention also provides a beverage making machine, including the body as described above and at least one functional module; Each of the aforementioned functional modules is assembled in the main unit housing and / or the cover.

[0028] Optionally, each of the functional modules includes a panel module, which is assembled at the cover, or the panel module constitutes the cover.

[0029] In the technical solution provided by this invention, one of the first body and the second body can be a main casing, and the other can be a cover. The pin assembly is mainly assembled at the first body, and a pin hole is provided at the corresponding position of the second body. The driving component can receive external driving force and be driven by the external driving force to perform its own movement stroke.

[0030] During its first stroke, the drive unit moves the pin to the first position. At this point, the pin is moved to engage with the pin hole, thus fixing the relative positions of the cover and the main housing.

[0031] During another stroke of its own movement, the drive unit can move the pin to a second position. At this point, the pin is moved to disengage from the pin hole, thereby separating the cover and the main housing from each other, making them independent of each other.

[0032] Since the movements of the pin and the drive component are different, their different directions and / or forms of movement allow for structural differentiation and separation in assembly orientation, effectively increasing the difficulty of accidental activation of the pin. Furthermore, to a certain extent, when the drive component remains stationary without external driving force, it acts as a limiting structure for the pin, preventing it from switching from the first position to the second, thereby effectively strengthening the connection between the first and second main bodies.

[0033] This invention helps reduce the risk of accidental touches and ensures that the cover and main body shell are firmly connected in the assembled state and do not interfere with each other in the detached state, which helps improve the overall quality of use of the device.

Detailed Implementation

[0037] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0038] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0039] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0040] Please see Figures 1 to 14 The present invention provides a latch assembly 300 and its applicable body and beverage making machine.

[0041] For ease of understanding, in the following embodiments, the description assumes that the latch assembly 300 and the body and beverage maker it are applied to have two generally perpendicular horizontal, vertical, and longitudinal directions. In a specific application, the vertical direction generally corresponds to the direction of gravity. The latch assembly 300 and the beverage maker have upper and lower sides located in the direction of gravity. The longitudinal direction generally corresponds to the front-to-back direction. The front of the latch assembly 300 and the beverage maker is generally the direction primarily facing the user. The horizontal direction generally corresponds to the left-to-right direction.

[0042] In view of the above, beverage making equipment generally includes a main body and at least one functional module. The main body generally includes a main housing 100, a cover, and a latch assembly 300.

[0043] The interior of the main unit housing 100 forms a mounting cavity. To enclose and define this mounting cavity, the main unit housing 100 may include, but is not limited to, a top shell plate, a bottom shell plate, and at least one side shell plate connecting the top shell plate and the bottom shell plate. The side shell plates may be correspondingly arranged on the front, rear, left, and right sides.

[0044] The specific types and quantities of the functional modules mentioned above are related to the types and quantities of operating modes pre-integrated into the beverage maker. For example, when the beverage maker has a grinding mode for grinding granular raw materials into powder, at least one functional module can be a grinding module. When the beverage maker has a mode for extracting powder into beverages, at least one functional module can be a brewing module. Furthermore, each functional module may also include, for example, a boiler assembly, a liquid supply module, a milk supply module, and a cleaning module.

[0045] In practical applications, the functional modules can be fully or partially housed within the mounting cavity of the main unit housing 100. Alternatively, the functional modules can be externally mounted on the main unit housing 100.

[0046] The mounting cavity has an opening 111. The opening 111 can be located at any position on the main unit housing 100. Figures 4 to 14 Taking the structure shown as an example, the opening 111 can be formed on the front side of the main housing 100. Based on this, the aforementioned lateral shell plates of the main housing 100 include a front shell plate 110 located on the front side of the entire machine, and two side shell plates 120 respectively disposed on the left and right sides of the front shell plate 110. The opening 111 is formed at the front shell plate 110. Specifically, the opening 111 can be formed across the entire surface of the front shell plate 110. Alternatively, the opening 111 can be formed on a portion of the surface of the front shell plate 110.

[0047] The cover is movably mounted on the main housing 100 and is provided corresponding to the opening 111. During the movement of the cover, it has a closed position for closing the opening 111 and an open position for opening the opening 111. When moved to the open position, the mounting cavity of the main housing 100 is opened, exposing at least one functional module assembled in the mounting cavity, which facilitates the disassembly, assembly, and maintenance of the functional module.

[0048] Of course, there are no restrictions on the way the cover can move to achieve the above purpose. It can be, but is not limited to, translation along a certain direction and / or rotation around an axis extending in a certain direction.

[0049] The cover can be directly configured as a relatively thin plate or sheet. In this case, at least one functional module can be selectively assembled onto the cover, depending on actual needs. Specifically, it can be assembled onto the back of the cover (the back being the side facing the mounting cavity).

[0050] Alternatively, the cover can be directly designed as a relatively thick block. In this case, an internal cavity can be pre-formed inside the cover, depending on actual needs. At least one functional module can be selectively assembled, either wholly or partially, within the internal cavity of the cover. Alternatively, at least one functional module can be selectively assembled to the back of the cover.

[0051] Specifically, the aforementioned functional modules may include panel module 200. Panel module 200 may be configured as a display module with only display function, an input module with only trigger input function, or a display control module with both display and trigger input functions, depending on actual needs.

[0052] The panel module 200 and the cover can be set separately, and the panel module 200 can be detachably or non-detachably assembled to the cover.

[0053] Alternatively, the panel module 200 and the cover can be integrally formed. In this case, the panel module 200 directly constitutes the aforementioned cover.

[0054] Next, one of the main body housing 100 and the cover can serve as the first main body 201, and the other can serve as the second main body 101. For ease of understanding, in the following embodiments, the cover is directly constructed from the panel module 200. The panel module 200 serves as the first main body 201, and the main body housing 100 serves as the second main body 101, as an example for explanation.

[0055] The pin assembly 300 can be specifically located at the panel module 200. Correspondingly, the main unit housing 100 has a pin hole 121. Please refer to... Figures 1 to 3 The pin assembly 300 may include a pin body 310 and a drive element 320.

[0056] The pin 310 is movably mounted on the first body 201, having a first position that is movable to be inserted into the pin hole 121 opened in the second body 101, and a second position that is dislodged from the pin hole 121 outward.

[0057] The drive element 320 is movably mounted on the first body 201 so that, after being driven by an external force, it drives the pin 310 to switch between a first position and a second position.

[0058] The movement of the pin 310 and the movement of the drive component 320 are configured differently.

[0059] In the technical solution provided by this invention, one of the first body 201 and the second body 101 can be a main casing 100, and the other can be a cover. The pin assembly 300 is mainly assembled at the first body 201, and a pin hole 121 is provided at the corresponding position of the second body 101. The driving member 320 can receive external driving force and be driven by the external driving force to perform its own movement stroke.

[0060] During its first stroke, the drive unit 320 can move the pin 310 to the first position. At this time, the pin 310 is moved to engage with the pin hole 121, thereby fixing the relative positions of the cover and the main housing 100.

[0061] During another stroke of its own movement, the drive unit 320 can move the pin 310 to a second position. At this time, the pin 310 is moved to disengage from the pin hole 121, thereby separating the cover and the main housing 100 from each other and making them independent of each other.

[0062] Since the movements of the pin 310 and the drive member 320 are different from each other, the pin 310 and the drive member 320 can be structurally distinguished and spatially separated by their different directions and / or forms of movement. This effectively increases the difficulty of accidental activation of the pin 310. Furthermore, to a certain extent, when the drive member 320 remains stationary without receiving external driving force, it acts as a limiting structure for the pin 310, preventing it from switching from the first position to the second position, thereby effectively strengthening the connection between the first body 201 and the second body 101.

[0063] This invention helps reduce the risk of accidental touch and ensures that the cover and main body shell 100 are firmly connected in the assembled state and do not interfere with each other in the detached state, which helps improve the overall quality of use of the machine.

[0064] It is understood that when the pin assembly 300 is applied between the main housing 100 and the panel module 200: after the panel module 200 is driven by an external force to move to the closed position, the drive member 320 can be driven by an external force, and drive the pin 310 to move to the first position. At this time, the pin 310 and the pin hole 121 are inserted into each other to lock and fix the panel module 200 in the closed position.

[0065] Conversely, when the drive component 320 is driven by an external force, causing the pin 310 to move to the second position, the pin 310 disengages from the pin hole 121 outwards, thus unlocking the panel module 200. At this time, the panel module 200 can move to the open position under the drive of an external force.

[0066] The activities of the pin 310 and the drive component 320 mentioned above are configured differently. The specific activities can be, but are not limited to, activity direction, activity form, and other activity schemes.

[0067] The movement of pin 310 is not limited. For example, pin 310 can translate along a certain direction, and / or pin 310 can rotate about an axis extending in a certain direction. However, to simplify the movement of pin 310, specifically, pin 310 can translate along a certain direction. This direction is defined as the first direction.

[0068] The movement of the drive member 320 is also not limited. For example, the drive member 320 can translate along a certain direction. And / or the drive member 320 can rotate about an axis extending in a certain direction.

[0069] By setting different motion schemes for the drive component 320 and the pin 310, it is possible to easily distinguish, change the force position or orientation, and adjust the speed.

[0070] Specifically, the movement direction of the pin 310 and the movement direction of the drive member 320 may be different. And / or, the movement form of the pin 310 and the movement form of the drive member 320 may be different.

[0071] For example, when the pin 310 translates along the first direction as described above, the drive member 320 can be rotatably configured about an axis extending along the second direction. The first and second directions intersect each other. In this way, the drive applied to the pin 310 along the first direction can be converted into a drive applied to the drive member 320 along the second direction. On the one hand, this prevents the travel of the drive member 320 from occupying too much space in the first body 201 in the first direction. That is, it helps to simplify the overall space occupied by the pin assembly 300 in the first direction. On the other hand, it helps to fully separate the drive member 320 and the pin 310 in terms of orientation, that is, to fully separate the force-bearing position of the drive member 320 and the insertion position between the pin 310 and the pin hole 121. This avoids excessive obstruction or obstruction of the pin hole 121 by the external force source (such as the user's hand) when an external force is applied to the drive member 320.

[0072] Specifically, please combine Figures 4 to 8 When the opening 111 is formed on the front shell plate 110 of the main unit housing 100, the opening 111 occupies a portion of the front shell plate 110. Furthermore, the opening 111 occupies the upper part of the front shell plate 110. This allows the panel module 200, which is movably positioned at the opening 111, to be appropriately raised, better matching the user's height and making the operation of the panel module 200 more comfortable for the user.

[0073] Specifically, the panel module 200 is rotatably mounted to the main housing 100. More specifically, the upper edge of the panel module 200 is rotatably mounted to the main housing 100 about an axis extending in a first direction. The lower edge of the panel module 200 constitutes the radial outer edge of the panel module 200.

[0074] Correspondingly, the first direction is left-right. The panel module 200 has a first shell wall 210 located at one of its rotation axis ends (i.e., the left or right side). A first mounting hole 211 is provided at the first shell wall 210 along the first direction. The pin 310 is movably mounted in the first mounting hole 211 to achieve translational movement along the first direction.

[0075] Next, the panel module 200 also has a second shell wall 220. The second shell wall 220 can be located at the radial outer end of the panel. A second mounting hole 221 is formed at the hole of the second shell wall 220, which connects to the first mounting hole 211. The driving member 320 is movably mounted in the second mounting hole 221. Correspondingly, the second direction is the radial direction of the panel module 200. In the closed position, the radial direction of the panel module 200 also corresponds to the vertical direction of the entire device.

[0076] The main housing 100 has a side shell plate 120 disposed relative to the first shell wall 210. The side shell plate 120 is provided with a pin hole 121. In this way, the pin hole 121 can be inserted into or separated from the left or right side of the whole machine. An external drive source (such as the user's hand) can be moved from the radial operation drive member 320 of the panel module 200.

[0077] Furthermore, after the panel module 200 is moved to the closed position, at least the radially outer end shell wall of the panel module 200 can be specifically configured to protrude from the front shell plate 110. That is, the second shell wall 220 at least partially protrudes forward from the front shell plate 110 at this time, so that at least the end of the drive member 320 installed at the second mounting hole 221 is exposed. An external driving source (such as a user's hand) can then find the end of the drive member 320 from the position where the lower end of the panel module 200 protrudes from the front shell plate 110 and apply force to the drive member 320, making it easier to achieve the purpose of operating the drive member 320.

[0078] Since the pin 310 extends elongatedly along the first direction, and needs to be aligned with the pin hole 121 during translational movement along the first direction to be smoothly inserted into the pin hole 121, in one embodiment, a rib 212 can be provided protruding from the wall of the first mounting hole 211. At least three ribs 212 are provided at equal intervals along the circumference of the first mounting hole 211. Each rib 212 extends elongatedly along the depth direction of the first mounting hole 211. The pin 310 movably passes through the first mounting hole 211 and movably abuts against each rib 212.

[0079] Each rib 212 serves two purposes: firstly, it raises the pin 310 relative to the wall of the first mounting hole 211, thus preventing contact between the pin 310 and the wall of the first mounting hole 211. This helps reduce the contact area between the radial outer wall of the pin 310 and the wall of the first mounting hole 211, making the translational movement of the pin 310 relative to the first mounting hole 211 easier and smoother. Secondly, the equidistant arrangement of multiple ribs 212 helps center the pin 310, ensuring that the orthographic projection of the pin 310 along the first direction falls within the pin hole 121, guaranteeing that the pin 310 can be smoothly inserted into the pin hole 121. Furthermore, it ensures that the central axis of the pin 310 and the central axis of the pin hole 121 are substantially aligned.

[0080] Please combine Figures 1 to 3 As shown, the pin 310 may include a first shaft segment 311 and a second shaft segment 312 connected sequentially along a first direction.

[0081] The first shaft segment 311 is mainly used for mating and insertion with the pin hole 121. Therefore, the size and shape of the first shaft segment 311 must be set to at least achieve the purpose of insertion with the pin hole 121.

[0082] During use, at least a portion of the second shaft segment 312 remains contained within the first mounting hole 211, ensuring that the pin 310 as a whole does not come out of the first mounting hole 211. At this time, the size and shape of the second shaft segment 312 can be specifically set according to the size and shape of the first mounting hole 211.

[0083] Correspondingly, the drive unit 320 includes a first drive segment 321 and a second drive segment 322 connected sequentially along the second direction.

[0084] The first drive segment 321 is mainly used to absorb external forces (such as driving forces applied by the user's hand). The first drive segment 321 may be entirely exposed outside the second mounting hole 221. Or at least the end of the first drive segment 321 may be exposed outside the second mounting hole 221.

[0085] During use, at least a portion of the second drive segment 322 remains contained within the mounting hole. This ensures that the entire drive component 320 does not protrude outward from the second mounting hole 221. Similarly, the size and shape of the second drive segment 322 can be specifically configured according to the size and shape of the second mounting hole 221.

[0086] In a specific embodiment, the first drive segment 321 may extend at least partially beyond the second mounting hole 221. This is to secure the drive component 320 within the second mounting hole 221. Furthermore, the housing also includes a limiting member 400. The limiting member 400 is detachably mounted to the second shell wall 220 to prevent the second drive segment 322 from disengaging outward from the second mounting hole 221.

[0087] For example, the first drive segment 321 itself, or the connection between the first drive segment 321 and the second drive segment 322, can form a downward-facing stepped surface. The limiting member 400 can be sleeved on the outside of the first drive segment 321 and connected and fixed to the second shell wall 220. After assembly, the limiting member 400 engages with the stepped surface stop.

[0088] More specifically, the limiting element 400 can be, for example... Figures 1 to 3 The screw shown is fixed at the second housing wall 220, which facilitates the detachable connection of the limiting member 400.

[0089] It should be noted that, in order to facilitate better application of force by an external driving source (such as a user's hand) to the first driving segment 321, the specific structure of the first driving segment 321 can be adjusted to suit the type of external driving source. For example, an anti-slip structure can be provided on the outer periphery of the first driving segment 321 to better accommodate the user's grip and rotation of the first driving segment 321. Alternatively, a slot or cross slot can be provided at the end of the first driving segment 321 to better accommodate the user's operation of the first driving segment 321 with tools.

[0090] Furthermore, when the drive member 320 only needs to rotate about an axis extending in the second direction, a sliding fit, for example, can be made between the second drive section 322 and the second mounting hole 221. However, when the drive member 320 needs to rotate about an axis extending in the second direction and also translate in the second direction (i.e., exhibiting an overall helical motion), one of the second drive section 322 and the second mounting hole 221 can be threaded internally, and the other can be threaded externally, allowing for a threaded fit between the internal and external threads.

[0091] The free end 332a (i.e., the end away from the first drive segment 321) of the second drive segment 322 described above forms a support surface 323. The second shaft segment 312 is cut axially to form an overlapping surface 313.

[0092] After assembly, the overlapping surface 313 is movably positioned on the support surface 323. Specifically, the overlapping surface 313 can overlap the support surface 323, achieving a sliding connection between the overlapping surface 313 and the support surface 323. Alternatively, the overlapping surface 313 can be suspended on the support surface 323, achieving a non-contact connection between the overlapping surface 313 and the support surface 323. Of course, for ease of understanding and to simplify the fit structure 342 between the two, the following embodiments will specifically illustrate the sliding connection between the overlapping surface 313 and the support surface 323. In this way, the support surface 323 can also provide vertical (e.g., at the closed position) stable support for the pin 310.

[0093] In the first direction, the length of the second drive segment 322 is less than the length of the second shaft segment 312. Thus, after the pin 310 moves to the first position, the lap surface 313 can still at least partially overlap the support surface 323. Furthermore, the sidewall of the second drive segment 322 will not interfere with the movement of the pin 310.

[0094] Because the second shaft segment 312 is partially defined by a planar cut along the axial direction (i.e., the first direction) to form the overlapping surface 313, the radial dimension of the second shaft segment 312 is smaller than that of the first shaft segment 311. Therefore, a stop surface facing the drive member 320 is formed at the connection between the two. When the stop surface is driven to abut against the side wall of the second drive segment 322, it can restrict the continued movement of the pin 310, thereby preventing excessive displacement of the pin 310.

[0095] Based on one or more of the above embodiments, the drive member 320 can achieve a transmission connection with the pin 310 in any manner. Specifically, the drive member 320 is provided with a reversing structure 341. The pin 310 is provided with a mating structure 342. The reversing structure 341 and the mating structure 342 are adapted to be connected to convert the rotational movement of the drive member 320 into the translational movement of the pin 310.

[0096] Of course, there are various designs for the reversing structure 341 and the mating structure 342. For example, one of the reversing structure 341 and the mating structure 342 may be gear teeth arranged sequentially along the first direction, while the other may be gear teeth arranged around the outer periphery of the second drive section 322. These two structures essentially constitute a gear and rack mechanism. Alternatively, for example, the reversing structure 341 may be a rocker arm, one end of which is rotatably connected to the drive member 320. The mating structure 342 may be a guide groove formed in the pin body 310 along the first direction. The other end of the rocker arm slides along the guide groove. These two structures essentially constitute a linkage mechanism.

[0097] When a support surface 323 and an overlapping surface 313 are respectively provided as described above, a reversing structure 341 can be directly provided on the support surface 323, and a mating structure 342 can be provided on the overlapping surface 313. Specifically, one of the reversing structure 341 and the mating structure 342 is a recessed groove 342a, and the other is a protruding post 341a. The post 341a and the groove 342a are inserted into each other and can be driven by the driving member 320 to generate relative rotation.

[0098] Specifically, for example Figures 1 to 3 Taking the structure shown as an example, a protruding post 341a may be provided on the support surface 323. A groove 342a may be provided on the lap surface 313. The protruding post 341a and the groove 342a are inserted into each other. And the groove 342a will not penetrate the pin 310 at least in the first direction. In this way, the groove 342a is located on the two side groove walls in the first direction, which is equivalent to forming the force-applying surface that pushes the protruding post 341a to reciprocate along the first direction.

[0099] Since the protrusion 341a is driven by the drive component 320 and rotates relative to the groove 342a, in practical applications, the outer diameter of the protrusion 341a can be appropriately designed to be smaller than the inner diameter of the groove 342a.

[0100] Furthermore, depending on actual needs, the groove 342a can penetrate the pin 310 along another direction intersecting the first direction (e.g., front-to-back direction). This creates an inlet / outlet on the side wall of the pin 310. The protrusion 341a can directly enter and exit the groove 342a through the opening of the groove 342a. Alternatively, the protrusion 341a can also enter and exit the groove 342a through the inlet / outlet. Especially when the opening of the groove 342a is appropriately recessed to restrict the protrusion 341a from disengaging from the groove 342a through the opening, the protrusion 341a can only enter and exit the groove 342a through the inlet / outlet.

[0101] Based on one or more of the above embodiments, please continue to combine... Figures 1 to 3 ,as well as Figures 9 to 14 Depending on actual needs, the pin assembly 300 may also include a locking element 330.

[0102] The locking member 330 is disposed between at least two of the driving member 320, the first body 201, and the pin 310. After the driving member 320 drives the pin 310 to the first position and the second position respectively, the locking member 330 maintains at least the fixed position between the driving member 320 and the first body 201.

[0103] During its first stroke, the drive member 320 moves the pin 310 to the first position. At this point, the pin 310 is engaged with the pin hole 121, thus fixing the relative positions of the cover and the main housing 100. Next, the locking member 330 maintains the fixed position between the drive member 320 and the first main body 201, ensuring that even if accidentally activated, the locking member 330 prevents the drive member 320 from moving relative to the first main body 201. Consequently, the pin 310 will not move relative to the first main body 201, and the pin 310 will be securely locked in the current first position, ensuring a stable assembly of the cover and the main housing 100.

[0104] During another stroke of its own movement, the drive member 320 can move the pin 310 to the second position. At this time, the pin 310 is moved to disengage from the pin hole 121, thereby separating the cover and the main body housing 100 from each other and making them independent. Then, the locking member 330 can maintain the fixed position between the drive member 320 and the first body 201, that is, even if it is accidentally activated, the locking member 330 can keep the drive member 320 from moving relative to the first body 201, so that the pin 310 will not move relative to the first body 201, and thus the pin 310 can be securely locked in the current second position, ensuring that the current disengaged state of the cover and the main body housing 100 is stable.

[0105] It is understood that the purpose of the locking member 330 is to lock the position between the driving member 320 and the first body 201 at least when the pin 310 moves to the first position, and to lock the position between the driving member 320 and the first body 201 at least when the pin 310 moves to the second position.

[0106] Of course, the locking member 330 can act directly between the driving member 320 and the first body 201. When the position between the driving member 320 and the first body 201 is locked, the driving member 320 and the pin 310, and the pin 310 and the first body 201 can also be indirectly locked.

[0107] In addition, the locking member 330 can also act directly between the driving member 320 and the pin 310. When the position between the driving member 320 and the pin 310 is locked, the driving member 320 and the first body 201, and the pin 310 and the first body 201 can also be indirectly locked.

[0108] Alternatively, the locking element 330 can also act directly between the pin 310 and the first body 201. When the position between the pin 310 and the first body 201 is locked, the driving element 320 and the first body 201, and the driving element 320 and the pin 310 can also be indirectly locked.

[0109] Specifically, taking the locking member 330 acting between the driving member 320 and the first body 201 as an example.

[0110] In one embodiment, the locking member 330 may be disposed on one of the first body 201 and the driving member 320, and is movable in the direction of approaching and away from the other. After the pin 310 is moved to the first position and the second position respectively, the locking member 330 abuts between the first body 201 and the driving member 320 to maintain the relative position of the driving member 320 and the first body 201 fixed.

[0111] For example, one end of the locking member 330 (hereinafter referred to as the fixed end for ease of understanding) is fixed to the first body 201, but the other end (hereinafter referred to as the movable end for ease of understanding) is movable near and away from the driving member 320 (not limited to the support surface 323).

[0112] At this time, when the pin 310 moves to the first or second position, the movable end of the locking member 330 moves closer to the driving member 320, interfering with the driving member 320 and preventing it from continuing to move, thus achieving the locking purpose. Conversely, when the pin 310 is between the first and second positions, the movable end of the locking member 330 moves away from the driving member 320, thus removing the interference with the driving member 320 and achieving the unlocking purpose.

[0113] And / or in one embodiment, the locking member 330 protrudes from one of the first body 201 and the drive member 320, and its free end 332a slides along the surface of the other. After the pin 310 is moved to the first position and the second position respectively, the locking member 330 abuts between the first body 201 and the drive member 320 to maintain the relative position of the drive member 320 and the first body 201 fixed.

[0114] Specifically, for example, one end of the locking member 330 (hereinafter referred to as the fixed end for ease of understanding) is fixed to the first body 201, while the other end (hereinafter referred to as the movable end for ease of understanding) also maintains sliding contact along the surface of the driving member 320 (not limited to the support surface 323). However, during the sliding contact process, the interference force applied by the locking member 330 to the surface of the driving member 320 changes.

[0115] When the pin 310 moves to the first or second position, the moving end of the locking member 330 applies a large interference force to the surface of the driving member 320. This interference force is sufficient to prevent the driving member 320 from continuing to move, thus achieving the locking purpose. Conversely, when the pin 310 is between the first and second positions, the moving end of the locking member 330 applies a small interference force to the surface of the driving member 320, which does not significantly hinder the continued movement of the driving member 320, thus achieving the unlocking purpose.

[0116] There are several ways to achieve the above-mentioned change in interference force. For example, the interference force can be different by smoothing a local area of ​​the surface of the driving component 320 (e.g., polishing it into a smooth surface, applying a lubricating coating, etc.) and / or roughening the remaining area of ​​the surface of the driving component 320 (corresponding to the first position and the second position, etc.) by using the difference in friction.

[0117] Of course, there are multiple ways to achieve the above-mentioned goal of stopping the price from falling.

[0118] In one specific embodiment, the free end 332a of the locking member 330 is provided with a connecting portion. A mating portion is provided on a partial surface of the first body 201 or the driving member 320 for sliding of the free end 332a of the locking member 330. After the connecting portion and the mating portion are connected, the locking member 330 abuts against the first body 201 and the driving member 320.

[0119] One of the connecting part and the mating part can be a magnetic attraction structure, and the other can be a magnetic mating structure 342. The magnetic attraction structure can be, but is not limited to, a magnet or an electromagnet. The magnetic mating structure 342 is made of a material containing at least one of iron, cobalt, and nickel. After the connecting part and the mating part are connected, they are magnetically fixed together, which can achieve the purpose of locking member 330 abutting between the first body 201 and the driving member 320.

[0120] Alternatively, one of the connecting part and the mating part can be a suction cup structure, and the other can form an adsorption surface. After the connecting part and the mating part are connected, they are adsorbed and fixed, which can achieve the purpose of locking the locking member 330 abutting between the first body 201 and the driving member 320.

[0121] Alternatively, in another embodiment, a slot is provided on a portion of the surface of the first body 201 or the driving member 320 on which the free end 332a of the locking member 330 slides. Two slots are spaced apart. The two slots are a first slot 351 corresponding to a first position and a second slot 352 corresponding to a second position. After the free end 332a of the locking member 330 engages with the slot, the locking member 330 abuts against the first body 201 and the driving member 320. Please refer to [the relevant documentation] for details. Figures 1 to 3 ,as well as Figures 9 to 14The support surface 323 may be provided with a first slot 351 and a second slot 352 spaced apart. The first main body 201 is provided with a locking member 330.

[0122] When the movable end of the locking member 330 needs to maintain sliding contact with the support surface 323, the locking member 330 can be made of at least a portion of an elastic material, so that at least a portion of the locking member 330 has sufficient elastic deformation capacity. Thus, when sliding along the surface of the first body 201 or the driving member 320, the locking member 330 is driven to compress and deform. When it moves to the first slot 351 or the second slot 352, the first slot 351 and the second slot 352 effectively create a clearance, allowing the locking member 330 to return to its original position and extend, achieving the purpose of engaging within the first slot 351 or the second slot 352.

[0123] The connection method between the locking component 330 and the first body 201, or between the locking component 330 and the driving component 320, is not limited. Taking the locking component 330 being located in the first body 201 as an example: the locking component 330 can be integrally formed with the first body 201. Alternatively, the locking component 330 and the first body 201 can be separately formed and then connected in a detachable or non-detachable manner.

[0124] In one embodiment, when a detachable connection is made, the surface of the first body 201 or the drive member 320 for the protruding locking member 330 is recessed with a mounting groove 222. The locking member 330 includes a fixed section 331 and a protruding section 332. The fixed section 331 is inserted and fixed in the mounting groove 222. The protruding section 332 extends outward from the opening of the mounting groove 222, and the end face of the protruding section 332 defines the free end 332a constituting the locking member 330.

[0125] The fixing section 331 and the mounting groove 222 can be directly interference-fitted. Alternatively, the fixing section 331 and the mounting groove 222 can be connected via a structure such as a snap-fit. Specifically, the mounting groove 222 includes a first groove section into which the fixing section 331 is inserted. The inner diameter of the first groove section gradually decreases from its opening to its bottom. In this case, the fixing section 331 can be designed as a uniform diameter section with a consistent outer diameter. Alternatively, the fixing section 331 can also be designed as a variable diameter section with a gradually decreasing outer diameter in the same direction. However, it should be emphasized that the outer diameter of the protruding section 332 is not less than the minimum inner diameter of the first groove section.

[0126] Thus, by adjusting the insertion depth of the fixing section 331 within the first groove, the insertion strength between the fixing section 331 and the first groove can be adjusted accordingly. This allows the same mounting groove 222 to accommodate locking components 330 of different sizes and specifications. This also reduces the molding requirements of the locking component 330 to some extent.

[0127] Next, the mounting groove 222 may further include a second groove segment. The second groove segment is located on the side of the first groove segment away from the bottom wall of the groove. The width of the second groove segment is greater than the width of the first groove segment. That is, the mounting groove 222 forms a flared opening at the second groove segment. When the locking member 330 is at least partially made of an elastic material as described above, the flared opening of the second groove segment can, to a certain extent, create clearance, reserving sufficient space for the locking member 330 to undergo the required compressive deformation.

[0128] Next, the locking member 330 also includes an annular step 333 connecting the fixed section 331 and the extended section 332. The outer diameter of the annular step 333 is smaller than the outer diameter of the second groove section, and larger than the inner diameters of the first groove section and the slot, respectively.

[0129] The annular step 333 has a first step surface 333a facing the fixed section 331. The first step surface 333a extends at an angle that gradually deviates from the fixed section 331 along its protruding direction. When the locking member 330 is compressed and subjected to an external force toward the bottom wall of the mounting groove 222, it is equivalent to the protruding section 332 and the annular step 333 being driven to move toward the first groove section. At this time, by setting the first step surface 333a at an angle, after the annular step 333 is driven into the first groove section, a gradually increasing abutting force is formed between it and the first groove section, preventing the protruding section 332 and the annular step 333 from retracting too much toward the first groove section. Conversely, when the compressing force applied to the locking member 330 is removed, by setting the first step surface 333a at an angle, it is equivalent to forming an inclined guide surface, which helps to release at least the annular step 333 that has retracted into the first groove section, thereby achieving a firm insertion between the protruding section 332 and the slot.

[0130] And / or, the annular step 333 has a second step surface 333b facing the protruding section 332, and the second step surface 333b is a flat surface. It can be understood that when the protruding section 332 is driven into the first slot 351 or the second slot 352, by providing the second step surface 333b, it is possible to achieve a tight fit between the second step surface 333b and, for example, the support surface 323 on the periphery of the first slot 351 or the second slot 352. Especially when the annular step 333 is made of an elastic material, and the corresponding positions of the second step surface 333b and the support surface 323 are sufficiently smooth, the annular step 333 essentially constitutes a suction cup structure, achieving negative pressure adsorption and fit with the support surface 323. This helps to further increase the locking strength between the driving member 320 and the first body 201 through negative pressure adsorption while the protruding section 332 and the slot are engaged.

[0131] Next, the surface of the free end 332a of the locking member 330 is provided in a convex arc shape. This greatly reduces the contact area between the free end 332a of the locking member 330 and the support surface 323 when the locking member 330 is driven to slide and abut against the support surface 323, thereby making the sliding smoother and less strenuous.

[0132] Furthermore, the first slot 351 and / or the second slot 352 can be configured as circular slots. That is, the inner wall of the first slot 351 and / or the second slot 352 is configured with a concave arc surface. This ensures that when the protruding section 332 of the locking member 330 needs to be moved outward from the first slot 351 or the second slot 352, the concave arc surface forms a guide surface, ensuring the smooth exit of the protruding section 332.

[0133] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
