Description

Technical Field

[0001] The utility model relates to the field of vehicles, in particular to a door limiting structure and a vehicle. Background Art

[0002] The vehicle door body is usually fixed to the door frame by a door limiting structure. The door limiting structure includes two parts, one is a limiting structure arranged on the door body, and the other is a lock buckle arranged on the door frame. When the door body is closed, the limiting structure is inserted into the lock buckle to achieve the limitation of the door body.

[0003] The limiting structure is set close to the edge of the door body, and the lock buckle protrudes from the door frame, so that when the door body is closed, the limiting structure can be inserted into the lock buckle. However, since the limiting structure is very close to the edge of the door body, the structural strength of the door body at this point is weakened, and it is easy to deform. In order to increase the structural strength of this part, the limiting structure is usually designed to be larger and more complex. Moreover, since the lock buckle protrudes from the door frame, when the user opens the door body, the lock buckle will be exposed, and the user can easily scratch the lock buckle when entering and exiting, which affects the user experience and also affects the visual perception. Utility Model Content

[0004] Therefore, an object of the present invention is to provide a door limiting structure and a vehicle to at least solve one of the problems existing in the above-mentioned prior art or related art.

[0005] A first aspect of an embodiment of the utility model provides a door limiting structure for a vehicle, the vehicle comprising a door body and a door frame adjacently distributed, the first end of the door body being pressed and arranged on the outer side of the first end of the door frame in an openable and closable manner; the door limiting structure comprises a buckle portion, the buckle portion being movably arranged on the back of the door body and not extending beyond the first end of the door body, and when the door body is in a closed state, the buckle portion can extend to the back of the first end of the door frame.

[0006] The door limiting structure provided in the embodiment of this aspect has a buckle part movably arranged on the back of the door body, and the movable range of the buckle part does not exceed the first end of the door body, and the installation position of the buckle part will leave a certain distance from the first end of the door body. On the one hand, the structural strength of the edge of the door body will not be affected by the close distance between the buckle part and the first end of the door body. On the other hand, the protruding buckle part will not be seen when observing the door body from the front, the buckle part is not easy to scratch the user, and the visual effect is improved.

[0007] Specifically, when the door body is in a closed state, the buckle part can be extended to the back of the door frame, so that the door frame can limit the opening of the door body and achieve the position limitation of the door body. It should be noted here that since the first end of the door body and the first end of the door frame are partially overlapped in the thickness direction of the door body, even if the buckle part extends to the back of the door frame, the buckle part can extend to the back of the first end of the door frame without exceeding the first end of the door body, thereby achieving the position limitation of the door body. And since the first end of the door frame is pressed by the door body, it is unnecessary to set a protruding buckle part on the door frame to fit close to the buckle part, thereby avoiding the protruding buckle part from scratching the user and improving the visual effect.

[0008] In addition, the door stop structure provided in the above embodiment of the present application may also have the following additional technical features:

[0009] In some embodiments, the door frame includes a door frame body and a bending portion arranged at the first end of the door frame body. The bending portion is bent backward relative to the door frame body so as to be located at the back of the door body, and the first end of the door body is pressed on the outside of the bending portion.

[0010] In these embodiments, a bending portion is provided at the first end of the door frame body, which is bent and extended toward the back of the door body so that the first end of the door body is pressed onto the bending portion. On the one hand, the bending portion can limit the door body from continuing to move inward, and on the other hand, the bending portion can be closer to the buckle portion, thereby facilitating the buckle portion to extend to the back of the bending portion without exceeding the door body, thereby limiting the door body from being opened.

[0011] Furthermore, the outer surface of the first end of the door body is flush with the outer surface of the first end of the door frame body, which has a good visual effect.

[0012] In some embodiments, the door limiting structure further includes: a seal, which is disposed on the bent portion for fitting with the back of the first end of the door body, or the seal is disposed on the back of the first end of the door body for fitting with the bent portion.

[0013] In these embodiments, the seal is disposed on the bending portion or on the door body. When the door body is in a closed state, the seal is clamped between the bending portion and the first end of the door body. Since the seal and the buckle portion are respectively located in front of and behind the bending portion, the two do not interfere with each other. The seal can seal a large area along the bending portion. Compared with the related art in which the seal needs to avoid the buckle portion or the buckle portion on the door frame, the seal can be continuously distributed, the structure is simple, and the sealing effect is good.

[0014] In some embodiments, the bending portion includes a first connecting plate, a second connecting plate and a third connecting plate connected in sequence, the first connecting plate is connected to the first end of the door frame body, the third connecting plate is located on the side of the first connecting plate away from the door frame, and is also located on the side of the first connecting plate close to the door body. The bending portion can form a roughly Z-shaped structure, which is simple in structure and easy to process.

[0015] In some embodiments, the seal comprises a U-shaped clamping portion and a hollow sealing strip located on one side of the U-shaped clamping portion, the end of the bent portion is inserted into the U-shaped clamping portion, and the hollow sealing strip is used to fit with the back of the first end of the door body. The seal can be firmly installed on the bent portion, and the hollow sealing strip is used to contact the door body, the seal has a certain deformation space, and the sealing effect is good.

[0016] In some embodiments, the door limiting structure further comprises a buckle portion arranged at the back of the first end of the door frame, and the buckle portion and the buckle portion are limitedly matched. By using the buckle portion and the buckle portion to cooperate, it is possible to avoid the buckle portion directly contacting the door frame and wearing the door frame.

[0017] In some embodiments, the buckle portion is a retractable lock tongue, which has a simple structure and is easy to process, and only needs to extend to the back of the door frame to limit the door body from being opened, which is convenient for limiting.

[0018] In some embodiments, the buckle portion is a locking tongue limiting plate, and the locking tongue can extend to the back of the locking tongue limiting plate to cooperate with the locking tongue limiting plate. The buckle portion has a simple structure and is easy to process.

[0019] In some embodiments, the buckle portion is a buckle slot, and the lock tongue can extend into the buckle slot. The buckle portion has a simple structure, is easy to process, and has a good limiting effect on the lock tongue.

[0020] In some embodiments, the buckle portion is a lock ring, and the lock tongue can extend and insert into the lock ring. The buckle portion has a simple structure, is easy to process, and has a good limiting effect on the lock tongue.

[0021] In some embodiments, a rotatable handle is provided on the outside of the door body, and a connecting arm is connected to the inside of the handle, and the connecting arm passes through the door body and is connected to the buckle part, and the buckle part can be driven away from the door frame when the handle rotates outward relative to the door body, so that the user can drive the buckle part to move by the handle, thereby releasing the limit on the door body and opening the door body conveniently.

[0022] In some embodiments, a lock core and a lock rod connected to the lock core are also provided on the door body. The lock rod can be moved to a locking position driven by the lock core to limit the rotation of the handle. The lock rod can also be moved away from the locking position driven by the lock core to release the limit on the handle.

[0023] In these embodiments, the lock rod can limit the rotation of the handle, thereby limiting the movement of the buckle part, and can achieve locking of the door body. When unlocking is required, the lock rod needs to be moved away from the locking position through the lock core, and then the handle is turned outward to drive the buckle part to move, so as to release the limit of the door frame on the door body and open the door body. The door body has dual protection of limit and lock, and has good safety. In addition, the locking of the door body uses the handle to limit the movement of the buckle part, and no additional locking structure is required, which can reduce parts and save costs.

[0024] In some embodiments, the vehicle comprises a frame, a part of which is configured as a door frame. At this time, the door body matched with the door frame is a single-opening door.

[0025] In some embodiments, the door body is a first door body, and the vehicle further comprises a second door body adjacent to the first door body, and the second door body is configured as a door frame of the first door body. In this case, the first door body and the second door body are double doors.

[0026] A second aspect of the present application provides a vehicle, comprising a door limiting structure as described in any one of the above embodiments.

[0027] The vehicle provided in the embodiment of this aspect has the door limiting structure of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be described in detail here.

[0028] Other aspects and / or advantages of the general inventive concept will be partially set forth in the following description, and some will be clear from the description or may be learned through implementation of the general inventive concept. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] The features described herein can be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided to illustrate only some of the many possible ways to implement the methods, devices, and / or systems described herein, which will be clear after understanding the disclosure of the present application.

[0074] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more.

[0075] Although terms such as "first", "second", and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions should not be limited by these terms.

[0079] Unless otherwise defined, all terms used herein, including technical terms and scientific terms, have the same meanings as those generally understood by ordinary technicians in the field to which the present invention belongs after understanding the present invention. Unless explicitly defined as such herein, terms such as those defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant field and the present invention, and should not be interpreted in an idealized or overly formal way.

[0080] In the related art, a limiting structure is usually set at the edge of the door body, and the lock buckle that cooperates with the limiting structure should protrude relative to the door frame to facilitate the limiting cooperation with the limiting structure. Moreover, in order to make the limiting structure smooth to use and compact in structure, the sealing structure of the door body is usually avoided, or the sealing structure is weakened near the limiting structure. However, this will lead to the following problems. First, the limiting structure is set close to the edge of the door body, which weakens the door frame structure here. In order to enhance the structural strength here, the door body structure here is usually made larger and more complicated; second, when the door body is opened, the lock buckle on the other side that cooperates with the door body will protrude from the door frame, and the limiting structure is also easy to protrude from the door body. When people enter or walk out of the car, it is easy to collide with the lock buckle or the limiting structure, affecting the user experience. Third, in order to avoid the door limiting structure, the seal is usually made more complicated, and it will also lead to a decrease in sealing performance.

[0081] Based on this, the embodiment of the present application proposes a door limit structure and a vehicle using the door limit structure, which can make the door limit structure away from the edge of the door body 10 to ensure the structural strength of the edge of the door body 10, and there is no protruding structure when the door body 10 is opened to avoid scratches or collisions with the user.

[0082] The following will be combined Figures 1 to 33 The door stop structure and vehicle provided by the embodiments of the utility model are introduced. Fig.13 and Fig.33 The same component in the figure, but one label has no a and the other has an a, only means that the component can be moved between the position without a and the position with a, and does not mean that there are two of the component.

[0083] like Figure 1 and Figure 3 As shown, the first embodiment of the utility model provides a door stop structure for a vehicle. The vehicle includes a door body 10 and a door frame 20 that are adjacently distributed, and the first end of the door body 10 is pressed on the outer side of the first end of the door frame 20 in an openable and closable manner. If the vehicle is a single-door vehicle, the door frame 20 can be a simple door frame structure. If the vehicle is a double-door vehicle, the door frame 20 can be another door body 10 adjacent to the door body 10, forming a double door body 10 that can be opened successively. The door stop structure can be used for both single-door vehicles and double-door vehicles.

[0084] like Figure 29 to Figure 33 As shown, the door limiting structure includes a snap-on portion 410, which is movably disposed on the back of the door body 10 and does not extend beyond the first end of the door body 10. When the door body 10 is in a closed state, the snap-on portion 410 can extend to the back of the first end of the door frame 20.

[0085] The door limiting structure provided in the embodiment of this aspect has the buckle portion 410 movably arranged on the back of the door body 10, and the movable range of the buckle portion 410 does not exceed the first end of the door body 10. The installation position of the buckle portion 410 can leave a certain distance from the first end of the door body 10. On the one hand, the structural strength of the edge of the door body 10 will not be affected by the close distance between the buckle portion 410 and the first end of the door body 10. On the other hand, the protruding buckle portion 410 will not be seen when observing the door body 10 from the front, the buckle portion 410 is not easy to be scratched by the user, and the visual perception is improved.

[0086] In a specific application, when the door body 10 is in a closed state, the buckle portion 410 is extended toward the back of the door frame 20, so that the door frame 20 can limit the door body 10 from being opened, thereby limiting the position of the door body 10. It should be noted here that since the first end of the door body 10 and the first end of the door frame 20 are partially overlapped in the thickness direction of the door body 10, even if the buckle portion 410 is extended toward the back of the door frame 20, the buckle portion 410 can extend to the back of the first end of the door frame 20 without exceeding the first end of the door body 10, thereby limiting the position of the door body 10. Since the first end of the door frame 20 is pressed by the door body 10, there is no need to set a protruding buckle portion 510 on the door frame 20 to fit close to the buckle portion 410, thereby avoiding the protruding buckle portion 510 from scratching the user and improving the visual effect.

[0087] Furthermore, if Figure 1 , Figure 2 and Figure 3 As shown, the door frame 20 includes a main body of the door frame 20 and a bending portion 210 disposed at a first end of the main body of the door frame 20. The bending portion 210 is bent backward relative to the main body of the door frame 20 so as to be located at the back of the door body 10. The first end of the door body 10 is pressed on the outside of the bending portion 210. The design of the bending portion 210 can, on the one hand, limit the door body 10 from continuing to move inward, and on the other hand, can be closer to the buckle portion 410, so that the buckle portion 410 can be extended to the back of the bending portion 210 without exceeding the edge of the door body 10, so as to hide the buckle portion 410 and limit the door body 10.

[0088] As an example, Figure 2 and Figure 3 As shown, the bending portion 210 includes a first connecting plate 211, a second connecting plate 212 and a third connecting plate 213 connected in sequence, the first connecting plate 211 is connected to the first end of the main body of the door frame 20, and the third connecting plate 213 is located on the side of the first connecting plate 211 away from the door frame 20, and is also located on the side of the first connecting plate 211 close to the door body 10. The bending portion 210 can form a roughly Z-shaped structure, which is simple in structure and easy to process.

[0089] In specific applications, such as Figure 3As shown, when the door body 10 is in a closed state and is pressed on the bent portion 210, the outer surface of the first end of the door body 10 can be flush with the outer surface of the first end of the main body of the door frame 20, which has a good visual effect.

[0090] Furthermore, if Figures 3 to 6 As shown, the door limiting structure also includes a seal 30, which is arranged on the bending portion 210 for fitting with the back of the first end of the door body 10, or the seal 30 is arranged on the back of the first end of the door body 10 for fitting with the bending portion 210.

[0091] Here, the seal 30 is arranged on the bending portion 210 or on the door body 10. When the door body 10 is in a closed state, the seal 30 is clamped between the bending portion 210 and the first end of the door body 10. Since the seal 30 and the buckle portion 410 are respectively located in front of and behind the bending portion 210, the two do not interfere with each other. The seal 30 can seal a large area along the bending portion 210. Compared with the related art in which the seal 30 needs to avoid the buckle portion 410 or the buckle portion 510 on the door frame 20, the seal 30 can be continuously distributed, the structure is simple, and the sealing effect is good.

[0092] As an example, Figure 2 and Figure 3 As shown, the seal 30 includes a U-shaped clamping portion 310U and a hollow sealing strip 320 located on one side of the U-shaped clamping portion 310U, the end of the bent portion 210 is inserted into the U-shaped clamping portion 310U, and the hollow sealing strip 320 is used to fit with the back of the first end of the door body 10. The seal 30 can be firmly installed on the bent portion 210, and the hollow sealing strip 320 is used to contact the door body 10. The seal 30 has a certain deformation space and a good sealing effect.

[0093] Furthermore, in some embodiments, Figure 3 As shown, the door limiting structure further includes a buckle portion 510 disposed at the back of the first end of the door frame 20, and the buckle portion 510 is limitedly matched with the buckle portion 410. By using the buckle portion 510 to cooperate with the buckle portion 410, it is possible to prevent the buckle portion 410 from directly contacting the door frame 20 and wearing the door frame 20.

[0094] As an example, Figure 21 to Figure 22 , Fig.29 As shown, the buckle portion 410 is a retractable lock tongue. The structure is simple, easy to process, and only needs to extend to the back of the door frame 20 to limit the door body 10 from being opened, and the limiting function is convenient.

[0095] As an example, Figure 3 As shown, the buckle portion 510 is a locking tongue limiting plate, and the locking tongue can extend to the back of the locking tongue limiting plate to cooperate with the locking tongue limiting plate. The buckle portion 510 has a simple structure and is easy to process.

[0096] As an example, the buckle portion 510 is a buckle slot, and the lock tongue can extend into the buckle slot. The buckle portion 510 has a simple structure, is easy to process, and has a good limiting effect on the lock tongue.

[0097] As an example, the buckle portion 510 is a lock ring, and the lock tongue can extend and insert into the lock ring. The buckle portion 510 has a simple structure, is easy to process, and has a good limiting effect on the lock tongue.

[0098] Furthermore, in some embodiments, Fig.28 and Fig.33 As shown, a rotatable handle 60 is provided on the outside of the door body 10, and a connecting arm 620 is connected to the inside of the handle 60. The connecting arm 620 passes through the door body 10 and is connected to the buckle portion 410. When the handle 60 rotates outward relative to the door body 10, the buckle portion 410 can be driven away from the door frame 20. It is convenient for the user to drive the buckle portion 410 to move through the handle 60, thereby releasing the limit on the door body 10 and facilitating the opening of the door body 10.

[0099] Furthermore, if Figures 25 to 33 As shown, a lock core 810 and a lock rod 820 connected to the lock core 810 are also provided on the door body 10. The lock rod 820 can be moved to a locking position driven by the lock core 810 to limit the rotation of the handle 60. The lock rod 820 can also be moved away from the locking position driven by the lock core 810 to release the limit on the handle 60.

[0100] Here, the lock rod 820 can be driven to rotate by the lock core 810, thereby limiting the rotation of the handle 60 and limiting the movement of the buckle part 410, so as to achieve the locking of the door body 10. When unlocking is required, the lock rod 820 needs to be moved away from the locking position by the lock core 810, and then the handle 60 is turned outward to drive the buckle part 410 to move, so as to release the limit of the door frame 20 on the door body 10, and then open the door body 10. The door body 10 has dual protection of limit and lock, and has good safety. In addition, the locking of the door body 10 uses the handle 60 to limit the movement of the buckle part 410, and no additional locking structure is required, which can reduce parts and save costs.

[0101] As an example, Figure 7 , Fig. 9 and Fig.10As shown, the door limiting structure includes a lock shell 710, and the handle 60 is rotatably arranged on the lock shell 710. The lock shell 710 is provided with two through holes 720, and the back of the lock shell 710 is provided with support arms 740, and the rotating shaft 640 is rotatably arranged on the support arms 740. The back of the handle body 610 is provided with a connecting arm 620 and a limiting arm 630. The connecting arm 620 extends out of the lock shell 710 through one through hole 720 and is connected to the rotating shaft 640. The limiting arm 630 extends out of the lock shell 710 through another through hole 720 and is connected to the rotating shaft 640. The handle body 610 can drive the rotating shaft 640 to rotate through the connecting arm 620 and the limiting arm 630 to realize the flipping of the handle 60. A part of the connecting arm 620 is connected to the buckle part 410 to drive the buckle part 410 to move. The limiting arm 630 can interfere with the lock rod 820.

[0105] Or further, the door body 10 is a first door body, and the vehicle further comprises a second door body 10 adjacent to the first door body, and the second door body 10 is configured as a door frame 20 of the first door body. In this case, the first door body and the second door body 10 are double doors.

[0106] The door stop structure and its assembly process according to an embodiment of the present application are described in detail below.

[0107] Figure 1 The exploded schematic diagram of the door stop structure is shown. The vehicle comprises a first door body and a second door body 10 which can be opened successively, and the door stop structure is arranged on the first door body and the second door body 10.

[0108] During the assembly process, you can first Figure 2 The parts shown in the figure are assembled together, including the following assembly steps:

[0109] Step 1: Assemble the rivet nut 220 onto the second door body 10 .

[0110] Step 2: Assemble the bent portion 210 to the rivet nut 220 of step 1 using the mounting screw 230 .

[0111] Step 3: snap the U-shaped snap-fit ​​portion 310 of the sealing member 30 onto the bent portion 210 .

[0112] Step 4: Install the lock tongue limiting plate at the reserved hole on the bending portion 210 using the rivet screws 240 .

[0113] The assembled structure is shown in Figures 3 to 6 .

[0114] Then, Figure 7 The parts shown in the figure are assembled together, including the following assembly steps:

[0115] Step 5: Weld the outer handle 611, the handle base 612, the connecting arm 620 and the limiting arm 630 together, refer to Figure 8 , forming an outer handle 611 welding sub-assembly.

[0116] Step 6: Weld the lock housing 710, the two support arms 740 and the mounting studs 730 together, refer to Fig. 9 , forming a lock housing 710 welding sub-assembly.

[0117] Step 7: Install the outer handle 611 welding subassembly and the lock housing 710 welding subassembly together using the rotating shaft 640, and bond the stopper 650 between the bottom surface of the lock housing 710 and the handle base 612. Fig.10 and Fig.11 Due to the existence of the rotating shaft 640, the outer handle 611 welding subassembly and the lock housing 710 welding subassembly can perform relative rotational motion within a certain angle range. Fig.12 and 13 As shown, the handle 60 can be at the position where the handle body 610 is located, and can also be rotated to the position where the handle body 610a is located.

[0118] Step 8: Weld the spring baffle 413 and the spring slide 411 together, as shown in FIG. Figures 14 to 17 As shown, the bolt sub-assembly is formed. And the bolt bottom shell 420, the bolt top shell 430 and the spring stop pin 440 are welded together, as shown in FIG. Figures 18 to 20 As shown, the bolt housing subassembly is formed. Then the two subassemblies are assembled together with the return spring 412, as shown in FIG. Figure 21 to Figure 24 When subjected to external force, the bolt sub-assembly and the bolt housing sub-assembly can slide relative to each other. When the external force is removed, due to the presence of the return spring 412, the two move in opposite directions until the return spring 412 returns to the state before compression, and the two stop moving relative to each other.

[0119] Step 9: Weld the sub-assemblies formed in Step 8 and Step 9 together, refer to Fig.25 , and screw the lock core 810 and the lock rod 820 together, such as Fig.26 and Fig. 27Insert the key into the appropriate position of the lock hole of the lock core 810, turn the key, and the lock rod 820 will rotate together to achieve the function of locking and unlocking.

[0120] Step 10: Install the sub-assembly formed in step 9 at the corresponding mounting hole 110 on the first door body; from the back of the first door body, use mounting bolts 760 to install the lock housing bent portion 750 to the sub-assembly formed in step 9, thereby clamping it on both sides of the first door body.

[0121] Specifically, refer to Fig.10 A mounting stud 730 is provided at the back of the lock housing 710 , and the mounting bolt 760 is inserted into the mounting stud 730 .

[0122] The door limit structure formed by the above steps is as follows: Figure 28 to Figure 33 shown.

[0123] like Fig.28 and Fig.29 As shown, when the door body 10 is in a closed state and the handle 60 is turned outward, the buckle portion 410 retracts. At this time, the user can pull the first door body outward to open the door.

[0124] like Fig.30 and Fig.31 As shown, when the door body 10 is in a closed state and the handle 60 is not turned outward, the buckle portion 410 extends to the back of the lock tongue limit plate under the action of the return spring 412, which can limit the first door body from being opened.

[0125] like Fig.32 and Fig.33 As shown, when the door body 10 is in the closed state and the handle 60 is not turned outward, the handle 60 is at the position of the handle body 610, and at this time, the connecting arm 620 will not push the buckle part 410 to retract. When the handle 60 is turned outward, the handle 60 is at the position of the handle body 610a, and at this time, one end of the connecting arm 620 can push the buckle part 410 to retract, thereby releasing the limit on the door body 10.

[0126] In addition, if Fig.29 As shown, when the lock cylinder 810 is not locked, the lock rod 820 is in Fig.29 In the position shown in FIG. 8 , if the handle 60 is turned over, the locking rod 820 will not interfere with the limiting arm 630, so that the handle 60 can be pulled outward to drive the buckle portion 410 to retract, thereby opening the door. Fig.31 In the locking position shown in , if the handle 60 is turned outward, the locking rod 820 will interfere with the limiting arm 630 to limit the movement of the handle 60, thereby preventing the handle 60 from driving the buckle part 410 to retract. At this time, the buckle part 410 will remain in the extended state to achieve locking of the first door body.

[0127] In this embodiment, the back of the handle body 610 has a connecting arm 620 and a limiting arm 630 distributed up and down. The connecting arm 620 can pass through the lock shell 710 and extend into the buckle portion 410, so as to push the buckle portion 410 to retract when the handle 60 is turned outward. The limiting arm 630 passes through the lock shell 710 and is used to cooperate with the lock rod 820 in a limiting manner.

[0128] The door stop structure of this embodiment does not need to be complicated for the door stop structure, the door opening is smooth after the door is opened, and there is no convex structure to affect the loading and unloading of goods or getting on and off the vehicle, and the user experience is good. In addition, the sealing member 30 does not need to be complicated for the door stop structure, and the sealing effect is good.

[0129] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that, in the opinion of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
