Description

[0001] This application claims priority to Taiwan Patent Application No. 112212501, filed on November 17, 2023, and Taiwan Patent Application No. 113205212, filed on May 21, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to a container door panel, and more particularly to a door panel locking structure and a substrate container having said door panel locking structure. Background Technology

[0003] In semiconductor or electronic circuit manufacturing processes, substrate containers are frequently used to handle and transfer substrates (such as wafers or circuit boards) to stably transport them to different process workstations, thus preventing damage from collisions during transport. Common substrate containers typically consist of a housing and a door panel, with the door panel fitting over the opening of the housing. In use, the door panel must first be unlocked and opened, then the substrate is inserted into or removed from the housing through the opening, and finally the door panel is closed and locked into the housing.

[0004] The typical locking mechanism between a door panel and its mounting box uses a parallel-extending latch that slides into a slot within the mounting box for locking. However, because the latch moves linearly, it can only lock the opposite side of the door panel. Therefore, if the mounting box is large, the door panel's area will also increase accordingly, potentially causing gaps, separation, or even deformation between the door panel and the mounting box on the latch-locking side.

[0005] In view of this, the applicant has devoted himself to researching and applying theoretical principles to address the shortcomings of the prior art, and has made every effort to solve the aforementioned problems, which has become the target of the applicant's improvement.

[0138] As used herein, terms such as “first,” “second,” “third,” “fourth,” and “fifth” describe various components, parts, regions, layers, and / or sections, which should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or section from another.

[0140] The detailed description and technical content of this application will be explained in conjunction with the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this application.

[0141] This application provides a door panel locking structure 100, please refer to... Figures 1 to 4 and Figure 8 As shown, it mainly includes a main frame plate 10, at least one drive turntable 20, at least a first driven component 30 and at least a second driven component 40.

[0142] In this embodiment, the main frame plate 10 includes a rectangular base plate 11 and an outer frame 12. The outer frame 12 is disposed at the periphery of the base plate 11, but this application is not limited to the above description. The outer frame 12 of the main frame plate 10 has at least one pair of through holes 13. Each of the through holes 13 is respectively disposed on adjacent sides of the outer frame 12 of the main frame plate 10 and near one of its corners, such as... Figure 3 As shown. In this embodiment, there are four pairs of perforations 13, each corresponding to one of the four corners of the outer frame 12, that is, there are eight perforations 13, to ensure that the four sides of the main frame plate 10 can be evenly stressed and stably locked. However, the number of perforations 13 in this application is not limited to this. It should be noted that, for the sake of convenience, the following description uses only one pair of perforations 13, and does not limit this application to only one pair of perforations 13.

[0143] The drive turntable 20 is rotatably mounted on the main frame plate 10. Specifically, the base plate 11 of the main frame plate 10 has at least one hollow cylinder 14, which is disposed on the same side as the outer frame 12 and within the surrounding area of ​​the outer frame 12. The drive turntable 20 is sleeved on the hollow cylinder 14 and can rotate on the hollow cylinder 14, but this application is not limited thereto. For example, the drive turntable 20 and the base plate 11 can also be pivotally connected by a shaft hole. The number of drive turntables 20 and hollow cylinders 14 is logarithmically arranged corresponding to the through holes 13. That is, in this embodiment, the number of drive turntables 20 and hollow cylinders 14 is four. For ease of description, the following description will only use a single drive turntable 20 and a single hollow cylinder 14, rather than limiting this application to only a single drive turntable 20 and a single hollow cylinder 14.

[0144] The number of first driven components 30 corresponds to the logarithmic arrangement of the perforations 13. Therefore, in this embodiment, there are four first driven components 30. For ease of description, only a single first driven component 30 will be used for explanation, rather than limiting this application to only having a single first driven component 30. The first driven component 30 is disposed on the main frame plate 10. One end of the first driven component 30 is connected to the drive turntable 20, and the other end of the first driven component 30 corresponds to one of the perforations 13. Specifically, the first driven component 30 includes a first driven locking bar 31, which is slidably disposed on the main frame plate 10, and both ends of the first driven locking bar 31 correspond to the drive turntable 20 and one of the perforations 13, respectively.

[0145] The number of second driven components 40 corresponds to the logarithmic arrangement of the perforations 13. Therefore, in this embodiment, there are four second driven components 40. For ease of description, only a single second driven component 40 will be used for explanation, rather than limiting this application to only having a single second driven component 40. The second driven component 40 is disposed on the main frame plate 10. One end of the second driven component 40 is connected to the drive turntable 20, and the other end of the second driven component 40 corresponds to another perforation 13. Specifically, the second driven component 40 includes a second driven locking bar 41, which is slidably disposed on the main frame plate 10. The two ends of the second driven locking bar 41 correspond to the drive turntable 20 and another perforation 13, respectively.

[0146] Therefore, when the drive turntable 20 rotates, it can simultaneously drive the first driven component 30 and the second driven component 40 to protrude out of or retract into the through holes 13 of the through holes 13, thereby locking the main frame plate 10 in different directions and enhancing the locking effect, thus preventing gaps, separation, or even deformation. Specifically, the drive turntable 20 has a first arc-shaped groove 21 and a second arc-shaped groove 22. The first driven component 30 also includes a first driven wheel 311, which is disposed on the first driven locking bar 31 and slidably accommodated in the first arc-shaped groove 21. The second driven component 40 also includes a second driven wheel 411, which is disposed on the second driven locking bar 41 and slidably accommodated in the second arc-shaped groove 22. Since the first driven wheel 311 and the second driven wheel 411 are respectively housed in the first arc-shaped groove 21 and the second arc-shaped groove 22, when the drive turntable 20 rotates, the first driven wheel 311 and the second driven wheel 411 can be driven to slide in the first arc-shaped groove 21 and the second arc-shaped groove 22, thereby simultaneously driving the first driven locking bar 31 and the second driven locking bar 41 to slide on the main frame plate 10, thereby causing the first driven component 30 and the second driven component 40 to protrude out of each through hole 13 of the through hole 13 or retract into each through hole 13.

[0147] It should be noted that in this embodiment, the number of first arc-shaped grooves 21 on the drive turntable 20 is two and they are arranged opposite each other, and the number of second arc-shaped grooves 22 on the drive turntable 20 is also two and they are arranged opposite each other. Therefore, since the number of first driven components 30 and second driven components 40 in this embodiment are both four, and they are respectively arranged at the four corners of the main frame plate 10 corresponding to each pair of through holes 13, the same drive turntable 20 can be used at different positions on the main frame plate 10, such as... Figure 5 Right now Figure 9 As shown, the four drive turntables 20 are completely identical. They only need to be installed at different positions in one of the first arc-shaped grooves 21 and one of the second arc-shaped grooves 22 corresponding to the drive turntable 20 at the position, so as to achieve a universal design and effect.

[0148] For further explanation, please refer to Figures 3 to 5 and Figures 8 to 9As shown, the first arc-shaped groove 21 has a first unlocking position 211 and a first locking position 212, and the second arc-shaped groove 22 has a second unlocking position 221 and a second locking position 222. The center of the first unlocking position 211 and the center of the drive turntable 20 form a first unlocking distance t11, and the center of the first locking position 212 and the center of the drive turntable 20 form a first locking distance t12. The center of the second unlocking position 221 and the center of the drive turntable 20 form a second unlocking distance t21, and the center of the second locking position 222 and the center of the drive turntable 20 form a second locking distance t22. The first unlocking distance t11 is smaller than the first locking distance t12. The second unlocking distance t21 is smaller than the second locking distance t22. Therefore, when the first driven wheel 311 moves from the first unlock position 211 to the first locked position 212, the first driven locking bar 31 moves away from the drive turntable 20, and vice versa. When the second driven wheel 411 moves from the second unlock position 221 to the second locked position 222, the second driven locking bar 41 moves away from the drive turntable 20, and vice versa.

[0149] It should be noted that the first unlocking position 211 and the first locking position 212 are respectively adjacent to the two ends of the first arc-shaped groove 21. Therefore, there is a gap between the first unlocking position 211 and the end adjacent to the first arc-shaped groove 21, and there is also a gap between the first locking position 212 and the end adjacent to the first arc-shaped groove 21. This can prevent the first driven wheel 311 from directly impacting the two ends of the first arc-shaped groove 21 and causing damage. Similarly, the second unlocking position 221 and the second locking position 222 are respectively adjacent to the two ends of the second arc-shaped groove 22. Therefore, there is a gap between the second unlocking position 221 and the end adjacent to the second arc-shaped groove 22, and there is also a gap between the second locking position 222 and the end adjacent to the second arc-shaped groove 22. This can prevent the second driven wheel 411 from directly impacting the two ends of the second arc-shaped groove 22 and causing damage.

[0150] See also Figure 3 , Figure 5 and Figure 9As shown, the door panel locking structure 100 of this application also includes at least one spring stop 18. The number of spring stop 18 corresponds to the number of drive turntables 20. Therefore, in this embodiment, there are four spring stop 18s. For ease of description, the following description will only use a single spring stop 18, and is not intended to limit this application to only a single spring stop 18. The spring stop 18 is disposed on the main frame plate 10 and is correspondingly disposed on the side of the drive turntable 20. The drive turntable 20 has multiple stops 24, each stop 24 is arranged in groups of two and is located on both sides of the spring stop 18. Each stop 24 is disposed at equal angles on the side of the drive turntable 20 facing the main frame plate 10, but this application is not limited to this. In this embodiment, four (i.e., two groups) stops 24 are provided on the drive turntable 20, thereby achieving a universal design and effect.

[0151] Specifically, such as Figure 9 As shown, when the first driven wheel 311 is in the first unlocked position 211 or the second driven wheel 411 is in the second unlocked position 221, one of the stops 24 of one of the group stops 24 abuts against one side of the spring stop 18; and as Figure 5 As shown, when the first driven wheel 311 is in the first locked position 212 or the second driven wheel 411 is in the second locked position 222, the other stop 24 of the group stop 24 abuts against the opposite side of the spring stop 18. In this way, each stop 24 is stopped by both sides of the spring stop 18, so that when the spring stop 18 and the stop 24 come into contact, the elastic force of the spring stop 18 itself can achieve a buffering effect, thereby stopping and positioning the drive turntable 20 during locking or unlocking, and thus extending the service life of the door panel locking structure 100.

[0152] See also Figures 3 to 5 and Figures 8 to 9As shown, the base plate 11 of the main frame plate 10 has a plurality of first positioning posts 15 and at least a pair of second positioning posts 16. In this embodiment, the first positioning posts 15 are arranged in pairs, and the second positioning posts 16 are arranged one by one and are respectively configured with a pair of through holes 13. Therefore, there are four sets of first positioning posts 15 and four sets of second positioning posts 16 in this embodiment. For ease of description, the following description will only use a single set of first positioning posts 15 and a single set of second positioning posts 16, and will not limit this application to only a single set of first positioning posts 15 and a single set of second positioning posts 16. The first positioning posts 15 are arranged in a straight line along the longitudinal direction of the main frame plate 10 on the longitudinal side of the drive turntable 20, and the second positioning posts 16 are located on the transverse side of the drive turntable 20. The first driven locking bar 31 has a plurality of first strip grooves 312, and the second driven locking bar 41 has a second strip groove 412. The first strip grooves 312 and the second strip grooves 412 are both elongated through grooves. The number of first strip grooves 312 and the number of second strip grooves 412 correspond to the number of first positioning posts 15 and the number of second positioning posts 16, respectively. Each first strip groove 312 is fitted with a first positioning post 15 to restrict the movement of the first driven locking bar 31 along the arrangement direction of the first positioning posts 15 (i.e., the longitudinal direction of the main frame plate 10). The second strip groove 412 is fitted with a second positioning post 16 to restrict the movement of the second driven locking bar 41 along the extension direction of the second strip groove 412 (i.e., the transverse direction of the main frame plate 10).

[0153] like Figure 4 and Figure 5 As shown, when the drive turntable 20 rotates and the first driven wheel 311 and the second driven wheel 411 are respectively in the first locked position 212 and the second locked position 222, since the first locking distance t12 and the second locking distance t22 are greater than the first unlocking distance t11 and the second unlocking distance t21, the first driven locking bar 31 moves away from the drive turntable 20 along the longitudinal direction of the main frame plate 10, and the second driven locking bar 41 also moves away from the drive turntable 20 along the transverse direction of the main frame plate 10, so that the first driven component 30 and the second driven component 40 protrude from each of the through holes 13 of the through holes 13 respectively.

[0154] like Figure 8 and Figure 9 As shown, when the drive turntable 20 rotates and the first driven wheel 311 and the second driven wheel 411 are respectively in the first unlock position 211 and the second unlock position 221, since the first unlocking distance t11 and the second unlocking distance t21 are smaller than the first locking distance t12 and the second locking distance t22, the first driven locking bar 31 moves closer to the drive turntable 20 along the longitudinal direction of the main frame plate 10, and the second driven locking bar 41 also moves closer to the drive turntable 20 along the transverse direction of the main frame plate 10, thereby causing the first driven component 30 and the second driven component 40 to retract into the respective holes 13 of the through holes 13.

[0155] See also Figure 3 , Figure 4 and Figure 8 As shown, in this embodiment, the first driven component 30 further includes a first hinge latch 32, and the second driven component 40 further includes a second hinge latch 42. The first hinge latch 32 is pivotally connected to the end of the first driven locking bar 31 away from the drive turntable 20 and is located at the corresponding through hole 13. The second hinge latch 42 is pivotally connected to the end of the second driven locking bar 41 away from the drive turntable 20 and is located at the corresponding through hole 13. Therefore, when the drive turntable 20 simultaneously drives the first driven locking bar 31 and the second driven locking bar 41 to slide, the first driven locking bar 31 drives the first hinge latch 32 to pivot relative to the first driven locking bar 31, protruding or retracting from the corresponding through hole 13. The second driven locking bar 41 drives the second hinge latch 42 to pivot relative to the second driven locking bar 41, protruding or retracting from the corresponding through hole 13, thereby preventing the through holes 13 of the outer frame 12 from being easily damaged or broken due to direct force.

[0156] It should be noted that the first hinge latch 32 and the second hinge latch 42 are not necessary limiting conditions of this application. When the first driven component 30 only includes the first driven locking bar 31 and the second driven component 40 only includes the second driven locking bar 41, the holes 13 of the through holes 13 can be protruded or retracted directly through the end of the first driven locking bar 31 away from the drive turntable 20 and the end of the second driven locking bar 41 away from the drive turntable 20, which can also achieve the same purpose and effect. Therefore, the first hinge latch 32 and the second hinge latch 42 should naturally not be regarded as necessary limiting conditions of this application, as stated in advance.

[0157] See also 1 to Figure 3 As shown, the door panel locking structure 100 of this application also includes a side cover plate 17. The side cover plate 17 is rectangular in shape, corresponding to the shape of the main frame plate 10. The side cover plate 17 is disposed on the side of the outer frame 12 away from the base plate 11, covering the main frame plate 10, and shields the drive turntable 20, the first driven component 30, and the second driven component 40, thereby preventing foreign objects from intruding and affecting the operation between the drive turntable 20, the first driven component 30, and the second driven component 40, and achieving both aesthetic and protective effects. In addition, please refer to... Figure 3 , Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown, the first hinge latch 32 is pivotally mounted on the inner side of the side cover plate 17 with a first pivot 321, and the second hinge latch 42 is pivotally mounted on the inner side of the side cover plate 17 with a second pivot 421, so that the first hinge latch 32 and the second hinge latch 42 can pivot relative to the side cover plate 17 respectively.

[0158] Please continue reading. Figures 1 to 2 , Figures 5 to 7and Figures 9 to 11 As shown, this application also provides a substrate container, which mainly includes a carrier box 500 and a door panel locking structure 100 as described above.

[0159] In this embodiment, the carrier box 500 is a rectangular box, but this application is not limited to this. The carrier box 500 has a cavity 501, an opening 502, and multiple slots 503. The cavity 501 is provided with multiple drawers (not labeled in the figure) for stacking substrates (not labeled in the figure) respectively. The opening 502 is located on one side of the carrier box 500 and communicates with the cavity 501. Each slot 503 is disposed at the opening 502 of the carrier box 500 and is configured corresponding to each through hole 13. The number of slots 503 corresponds to the number of through holes 13. Therefore, in this embodiment, there are eight slots 503. For ease of description, only one pair (two) slots 503 will be described below, rather than limiting this application to only two slots 503.

[0160] The main frame plate 10 covers and closes the cavity 501 corresponding to the opening 502. Each slot 503 of the card slot 503 is configured to correspond to each through hole 13 of the through hole 13, that is, each slot 503 of the card slot 503 is located on the adjacent sides of the opening 502 of the carrier box 500.

[0161] Therefore, when the drive turntable 20 rotates, causing the first driven component 30 and the second driven component 40 to protrude from or retract into the through holes 13, the first driven component 30 and the second driven component 40 extend into or disengage from the slots 503, thereby locking the main frame plate 10 at or releasing it from the opening 502. Since there are four first driven components 30 and four second driven components 40 in this embodiment, when the first driven components 30 and the second driven components 40 are locked at the opening 502 of the carrier box 500, both the longitudinal and transverse directions of the main frame plate 10 can be locked simultaneously, and all four sides of the main frame plate 10 can be secured, thereby effectively enhancing the locking effect and preventing gaps, separation, or even deformation between the main frame plate 10 and the carrier box 500.

[0162] For further explanation, please refer to Figure 13 As shown, the carrier box 500 also has a plurality of abutment ribs 5031 formed at the slot 503. Specifically, each abutment rib 5031 is provided on the side of each slot 503 away from the cavity 501, and the first hinge latch 32 and the second hinge latch 42 respectively have a first latching portion 322 and a second latching portion 422. Thus, when the first driven assembly 30 or the second driven assembly 40 locks the main frame plate 10 in the opening 502, the first latching portion 322 of the first hinge latch 32 or the second latching portion 422 of the second hinge latch 42 will engage with the abutment ribs 5031 in the corresponding slot 503 (as can be seen in...). Figure 6 and Figure 7 This forces the door panel locking structure 100 toward the cavity 501 through a reaction force, thereby improving the locking effect.

[0163] See also Figure 6 and Figure 7 As shown, the substrate container of this application also includes a sealing ring 700. A frame-shaped groove 111 is formed on the side of the main frame plate 10 away from the side cover plate 17, and the sealing ring 700 is fitted and secured in the frame-shaped groove 111. An abutment portion 504 is formed on the inner side of the carrier box 500 at the opening 502. Therefore, when the door panel locking structure 100 is pressed against the cavity 501, the sealing ring 700 is elastically clamped between the frame-shaped groove 111 of the door panel locking structure 100 and the abutment portion 504 of the carrier box 500, thereby enabling the substrate container of this application to achieve an airtight and dustproof effect. The technical means of this application is to engage the first latching portion 322 of the first hinge latch 32 or the second latching portion 422 of the second hinge latch 42 with the abutting ribs 5031 in the slot 503, so that the door panel locking structure 100 is pressed toward the cavity 501 and a seal is formed by the sealing ring 700. Compared with conventional simple bolts or buckles, it can effectively avoid dust generated by friction when unlocking or locking, thereby ensuring the dust-free standard of the working environment, and can also effectively improve the durability of the door panel locking structure 100.

[0164] See also Figure 1 and Figure 2 As shown, the substrate container of this application also includes at least one unlocking device 600. The drive turntable 20 has a rectangular groove 23 at its center. Although not shown in detail, the unlocking device 600 mainly includes a handle, a connecting rod, and a plug. The connecting rod connects the handle and the plug, allowing the user to grip the handle and rotate the plug via the connecting rod. The plug of the unlocking device 600 can be fitted into the groove 23 of the drive turntable 20, thereby rotating the drive turntable 20 by rotating the handle of the unlocking device 600, which in turn actuates the first driven component 30 and the second driven component 40. Furthermore, the side cover plate 17 has multiple through slots 171 corresponding to the shape of the plug. Each through slot 171 allows the plug and connecting rod of the unlocking device 600 to pass through, so that the plug is fitted into the groove 23, and the handle of the unlocking device 600 is exposed on the side cover plate 17 for the user to rotate and use.

[0165] Please continue reading. Figure 12 As shown, the connection between the first driven wheel 311 and the first driven locking bar 31 and the connection between the second driven wheel 411 and the second driven locking bar 41 will be further explained below.

[0166] The first driven locking bar 31 has a first pivot hole 313 at one end connected to the drive turntable 20. The first driven wheel 311 is pivotally mounted in the first pivot hole 313. The second driven locking bar 41 has a second pivot hole 413 at one end connected to the drive turntable 20. The second driven wheel 411 is pivotally mounted in the second pivot hole 413. Therefore, whether the first driven wheel 311 slides in the first arc-shaped groove 21 or the second driven wheel 411 slides in the second arc-shaped groove 22, both the first driven wheel 311 and the second driven wheel 411 can slide in a rotating manner, thereby avoiding excessive friction between some surfaces and the first arc-shaped groove 21 or the second arc-shaped groove 22, and thus effectively increasing the service life of the door panel locking structure 100. In this embodiment, both the first driven wheel 311 and the second driven wheel 411 are integrally molded from plastic injection molding, but this application is not limited to this.

[0167] Specifically, the first driven component 30 further includes a first latching member 33, and the second driven component 40 further includes a second latching member 43. In this embodiment, both the first latching member 33 and the second latching member 43 are C-shaped buckles, but this application is not limited thereto. The first driven wheel 311 has a first groove 3111 at one end extending out of the first driven locking bar 31. The first latching member 33 is fastened and fixed to the first groove 3111, thereby rotatably restricting the first driven wheel 311 to the first driven locking bar 31 and preventing it from easily disengaging. The second driven wheel 411 has a second groove 4111 at one end extending out of the second driven locking bar 41. The second latching member 43 is fastened and fixed to the second groove 4111, thereby rotatably restricting the second driven wheel 411 to the second driven locking bar 41 and preventing it from easily disengaging.

[0168] Please continue reading. Figures 14 to 16 As shown, the second embodiment of this application differs from the first embodiment mainly in the material and specific structure of the first driven wheel 311 and the second driven wheel 411, which are described in detail below.

[0169] like Figure 15As shown, the first driven wheel 311 includes a first shaft 311A ​​and a first bearing 311B, and the second driven wheel 411 includes a second shaft 411A and a second bearing 411B. The first shaft 311A ​​is generally cylindrical and has the aforementioned first groove 3111 and first step 3112. The first pivot hole 313 of the first driven locking bar 31 is sleeved and fixed on the first step 3112, and the first bearing 311B is sleeved and fixed on the first shaft 311A ​​and located between the first snap fastener 33 and the first driven locking bar. The second shaft 411A is generally cylindrical and has the aforementioned second groove 4111 and second step 4112. The second pivot hole 413 of the second driven locking bar 41 is sleeved and fixed on the second step 4112, and the second bearing 411B is sleeved and fixed on the second shaft 411A and located between the second snap fastener 43 and the second driven locking bar. In this embodiment, the first shaft 311A, the first bearing 311B, the second shaft 411A and the second bearing 411B are all metal parts with good structural strength, but the materials of the first shaft 311A, the first bearing 311B, the second shaft 411A and the second bearing 411B are not limited thereto.

[0170] By splitting the first driven wheel 311 into a first shaft 311A ​​and a first bearing 311B made of metal, and splitting the second driven wheel 411 into a second shaft 411A and a second bearing 411B made of metal, the structural strength of the first driven wheel 311 and the second driven wheel 411 is increased. Therefore, when the first driven assembly 30 or the second driven assembly 40 is in operation, the friction of the first driven wheel 311 or the second driven wheel 411 will not be too great and unable to rotate due to the first driven locking bar 31 or the second driven locking bar 41 being misaligned, thus affecting the smoothness of the rotation of the drive turntable 20 during operation.

[0171] Furthermore, the first driven wheel 311 also includes a first washer 311C, and the second driven wheel 411 also includes a second washer 411C. The first washer 311C is sleeved on the first shaft 311A ​​and located between the first bearing 311B and the first driven locking bar 31. The second washer 411C is sleeved on the second shaft 411A and located between the second bearing 411B and the second driven locking bar 41. In this way, the positions of the first bearing 311B and the second bearing 411B can be adjusted respectively by the first washer 311C and the second washer 411C, thereby ensuring that the position of the first bearing 311B is within the first arc-shaped groove 21, and the position of the second driven wheel 411 is within the second arc-shaped groove 22, and eliminating manufacturing tolerances between the components.

[0172] Please continue reading. Figures 17 to 21As shown, the main difference between the third embodiment of this application and the first embodiment lies in that the side cover 17 has a first limiting rib 172 and a second limiting rib 173. Specifically, the first limiting rib 172 protrudes from the side cover 17 toward the first driven wheel 311 and extends along the sliding direction of the first driven assembly 30, and the second limiting rib 173 protrudes from the side cover 17 toward the second driven wheel 411 and extends along the sliding direction of the second driven assembly 40. Please refer to [link to relevant documentation]. Figure 18 and Figure 20 As shown, when the drive turntable 20 rotates, causing the first driven component 30 and the second driven component 40 to protrude from the through holes 13, thereby allowing the first driven component 30 and the second driven component 40 to extend into the slots 503, the side of the first driven wheel 311 away from the first driven locking bar 31 is restricted by the first limiting rib 172, while the side of the second driven wheel 411 away from the second driven locking bar 41 is restricted by the second limiting rib 173. Therefore, the operation of the first driven component 30 and the second driven component 40 will not be affected by the step jamming of the side cover plate 17. Please refer to [further details omitted]. Figure 19 and Figure 21 As shown, when the drive turntable 20 rotates, causing the first driven component 30 and the second driven component 40 to retract into their respective through holes 13, thereby disengaging the first driven component 30 and the second driven component 40 from their respective slots 503, the side of the first driven wheel 311 away from the first driven locking bar 31 is still restricted by the first limiting rib 172, and the side of the second driven wheel 411 away from the second driven locking bar 41 is also still restricted by the second limiting rib 173. Therefore, the operation of the first driven component 30 and the second driven component 40 will not be affected by the step jamming of the side cover plate 17.

[0173] Please continue reading. Figure 22 and Figure 23 As shown, the main difference between the fourth embodiment of this application and the second embodiment is that it does not include the first fastener 33 and the second fastener 43. Instead, the first bearing 311B is tightly fastened to the outer edge of the first shaft 311A ​​by the inner wall of the first bearing 311B and to the outer edge of the second shaft 411A by the inner wall of the second bearing 411B, so that the first bearing 311B and the second bearing 411B can be firmly fixed and will not fall off.

[0174] Please refer to the following: Figure 24 and Figure 25As shown, the fifth embodiment of this application differs from the fourth embodiment mainly in that the first driven component 30 further includes a first fixing member 34, and the second driven component 40 further includes a second fixing member 44. The first fixing member 34 is fixed to the end face of the first shaft 311A ​​away from the first driven locking bar 31, and stops the first bearing 311B away from the end face of the first driven locking bar 31 to prevent the first bearing 311B from falling off. The second fixing member 44 is fixed to the end face of the second shaft 411A away from the second driven locking bar 41, and stops the second bearing 411B away from the end face of the second driven locking bar 41 to prevent the second bearing 411B from falling off. In this embodiment, both the first fixing member 34 and the second fixing member 44 are bolts, and each is used with a washer (not labeled in the figure). However, this application is not limited to this. For example, the bolts of the first fixing member 34 and the second fixing member 44 can also be used alone, or both the first fixing member 34 and the second fixing member 44 can be rivets. It is worth noting that, since the first bearing 311B and the second bearing 411B are stopped by the first fixing member 34 and the second fixing member 44 respectively, it is not necessary for the first bearing 311B and the second bearing 411B in this embodiment to be tightly fitted and fastened to the first shaft 311A ​​and the second shaft 411A.

[0175] The door panel locking structure 100 and the substrate container having the door panel locking structure 100 of this application, by providing a drive turntable 20, a first driven component 30 and a second driven component 40 on the main frame plate 10, enable the drive turntable 20 to simultaneously drive the first driven component 30 and the second driven component 40 to operate when rotating, thereby allowing the first driven component 30 and the second driven component 40 to protrude out of each through hole 13 or retract into each through hole 13, thereby simultaneously locking the main frame plate 10 in different directions and enhancing the overall locking effect, thereby preventing gaps, separation or even deformation of the door panel.

[0176] This application may have other various embodiments. Without departing from the spirit and essence of this application, those skilled in the art can devise various corresponding changes and modifications based on this application. However, all such corresponding changes and modifications should fall within the protection scope of the patent application filed in this application.
