[0025] Embodiment 1

[0026] As Figure 1 and Figure 2 shown, the lock includes a panel 10, a bracket 20, a fastener 30 and a sealing structure 40. The panel 10 has a first mating portion 11. The bracket 20 has a second mating portion 21 and a button hole 22 which are spaced apart. One of the first mating portion 11 and the second mating portion 21 is a protrusion, and the other of the first mating portion 11 and the second mating portion 21 is a recess. The protrusion extends into the recess and is in stop fit with the recess. The fastener 30 is passed through the panel 10 and the bracket 20 to connect the panel 10 and the bracket 20. The sealing structure 40 is disposed between the panel 10 and the bracket 20. Among them, the sealing structure 40 is made of at least one of rubber, silica gel and cotton pad.

[0027] Applying the technical solution of this embodiment, the panel 10 and the bracket 20 of the lock are assembled together by combining the stop fit of the first engaging portion 11 and the second engaging portion 21 and the fastening of the fastener 30. This not only facilitates the disassembly and assembly of the panel 10 and the bracket 20, but also improves the connection stability between the two. In this way, the sealing structure 40 is arranged between the panel 10 and the bracket 20 to seal the connection between the two, thereby avoiding dust and other impurities from entering the lock through the connection between the two, solving the problem in the prior art that dust and other impurities easily enter the lock through the connection between the bracket and the front panel, and ensuring the normal use of the lock.

[0028] In this embodiment, the sealing structure 40 is made of rubber, thereby reducing the processing cost of the sealing structure 40 on the premise of ensuring the sealing reliability.

[0029] In this embodiment, the first engaging portion 11 is a concave portion, and the second engaging portion 21 is a convex portion. The second engaging portion 21 extends into the first engaging portion 11 and is in snap fit with the first engaging portion 11.

[0030] In other embodiments not shown in the drawings, the first engaging portion is a convex portion, the second engaging portion is a first concave portion, and the first engaging portion extends into the second engaging portion and is in snap fit with the second engaging portion.

[0031] Optionally, there are multiple first engaging portions 11, and the multiple first engaging portions 11 are arranged at intervals along the circumference of the bracket 20. There are multiple second engaging portions 21, and the multiple second engaging portions 21 are arranged in one-to-one correspondence with the multiple first engaging portions 11. In this way, the above arrangement can increase the mating area between the first engaging portion 11 and the second engaging portion 21 to improve the assembly stability between the panel 10 and the bracket 20. At the same time, the above arrangement makes the selection of the number of the first engaging portion 11 and the second engaging portion 21 more flexible and diverse to adapt to different working conditions and usage requirements, thereby improving the processing flexibility of the staff.

[0032] In this embodiment, there are four first engaging portions 11, and the four first engaging portions 11 are arranged at intervals along the circumference of the bracket 20; there are four second engaging portions 21, and the four second engaging portions 21 are arranged in one-to-one correspondence with the four first engaging portions 11.

[0033] Specifically, two first engaging portions 11 are arranged on each of the two opposite sides of the bracket 20, so that the panel 10 can be snap-fitted and fixed to the bracket 20 from both sides of the bracket 20, further improving the assembly stability between the panel 10 and the bracket 20.

[0034] It should be noted that the number of the first engaging portions 11 is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the first engaging portion 11 is two, or three, or five, or six, or seven, or eight, or multiple.

[0035] It should be noted that the number of the second mating parts 21 is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the number of the second mating parts 21 is two, or three, or five, or six, or seven, or eight, or more.

[0036] Optionally, the sealing structure 40 is annular and arranged around the keyhole 22; or, the sealing structure 40 includes a plurality of sealing segments arranged around the keyhole 22. In this way, on the premise of sealing the connection between the panel 10 and the bracket 20, the sealing structure 40 can also seal the position of the keyhole 22, thereby preventing impurities such as dust from entering the lock through the keyhole 22, and also improving the sealing reliability of the sealing structure 40.

[0037] In this embodiment, the sealing structure 40 is annular and arranged around the keyhole 22, so that the structure of the sealing structure 40 is simpler and the processing cost of the sealing structure 40 is reduced.

[0038] Optionally, there is one sealing structure 40; or, there are a plurality of sealing structures 40, and the plurality of sealing structures 40 are arranged at intervals along the direction from the keyhole 22 to the sealing structure 40; and / or, the plurality of sealing structures 40 are arranged at intervals along the thickness direction of the bracket 20. In this way, the above settings make the selection of the number and the setting position of the sealing structure 40 more flexible to meet different usage requirements and working conditions, and also improve the processing flexibility of the staff.

[0039] In this embodiment, there is one sealing structure 40, and the sealing structure 40 is an annular structure and arranged around the keyhole 22.

[0040] In other embodiments not shown in the drawings, there are a plurality of sealing structures, and the plurality of sealing structures are arranged at intervals along the direction from the keyhole to the sealing structure.

[0041] In other embodiments not shown in the drawings, there are a plurality of sealing structures, and the plurality of sealing structures are arranged at intervals along the thickness direction of the bracket.

[0042] In other embodiments not shown in the drawings, there are a plurality of sealing structures, a part of the plurality of sealing structures are arranged at intervals along the direction from the keyhole to the sealing structure, and another part of the plurality of sealing structures are arranged at intervals along the thickness direction of the bracket.

[0043] In this embodiment, the panel 10 has a receiving cavity 12, the first mating part 11 is arranged on the bottom wall 121 of the receiving cavity 12, and the sealing structure 40 is located between the second mating part 21 and the keyhole 22. In this way, the above settings make the structural layout of the sealing structure 40 in the lock more reasonable and compact, improving the space utilization rate inside the lock while ensuring the sealing reliability.

[0044] Optionally, the sealing structure 40 is strip-shaped, and the cross-section of the sealing structure 40 is circular, or polygonal, or semi-circular, or elliptical. In this way, the above setting makes the cross-sectional shape of the sealing structure 40 more diverse to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0045] In this embodiment, the cross-section of the sealing structure 40 is circular, so that the structure of the sealing structure 40 is simpler, easier to process and implement, and reduces the processing cost and difficulty of the sealing structure 40.

[0046] Optionally, the fastener 30 is a screw or a bolt, and the lock further includes a sealing gasket. The sealing gasket is arranged between the head of the screw or bolt and the panel 10 or the bracket 20. In this way, the above setting of the sealing gasket further improves the sealing performance at the connection between the fastener 30 and the panel 10 and the bracket 20, and prevents dust and other impurities from entering the lock through the above connection and affecting the normal use of the lock.

[0047] Optionally, the panel 10 includes a base plate and a surrounding plate. The base plate has an installation hole for installing the touch panel 60, and the first fitting portion 11 is arranged on the inner plate surface of the base plate. The surrounding plate is arranged on the inner plate surface of the base plate and forms an installation cavity with the base plate around it. The first fitting portion 11 is arranged on the inner plate surface and / or the surrounding plate. In this way, the bracket 20 is arranged on the inner plate surface of the base plate through the first fitting portion 11, and the touch panel 60 is installed on the base plate through the installation hole. The touch function of the touch panel 60 is realized by the cooperation of the touch panel 60 and the bracket 20. At the same time, the above setting makes the setting position of the first fitting portion 11 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0048] In this embodiment, the first fitting portion 11 is arranged on the surrounding plate.

[0049] In other embodiments not shown in the drawings, the first fitting portion is arranged on the base plate.

[0050] In other embodiments not shown in the drawings, the first fitting portion is arranged on the base plate and the surrounding plate.

[0051] Specifically, a PCB board 50 is further arranged between the bracket 20 and the touch panel 60. A plurality of pits are arranged on the bracket 20, and the pits are used to reflect the light emitted by the PCB board 50 to the numeric keys of the touch panel 60 to realize the backlight function of the touch panel 60.

[0052] As Figure 1As shown, the first mating portion 11 is a recess, and the panel 10 is further provided with a relatively arranged first plate body 15, a second plate body 16 and a third plate body 17. The first plate body 15 and the second plate body 16 are connected by the third plate body 17 and are located on the same side of the third plate body 17. A first included angle is formed between the first plate body 15 and the third plate body 17, and a second included angle is formed between the second plate body 16 and the third plate body 17. Among them, the first plate body 15, the second plate body 16, the third plate body 17 and at least part of the panel 10 surround to form a recess. In this way, the above settings make the structure of the recess simpler, easier to process and implement, thereby reducing the processing difficulty of the staff. At the same time, the staff can change the shape of the recess by changing the sizes of the first included angle and the second included angle, so as to ensure that the shape of the recess matches the shape of the convex portion, thereby improving the versatility of the recess.

[0053] In this embodiment, the first included angle is 90°, the second included angle is 90°, and the recess is a rectangular hole.

[0054] It should be noted that the selection of the first included angle is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the first included angle is 60°, or 70°, or 80°, or 100°, or 110°.

[0055] It should be noted that the selection of the second included angle is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the second included angle is 60°, or 70°, or 80°, or 100°, or 110°.

[0056] Specifically, the plate surface of the third plate body 17 away from the surrounding plate is an inclined surface, and the surface of the second mating portion 21 facing the surrounding plate is an inclined surface, and the two inclined surfaces cooperate with each other. When assembling the bracket 20 and the panel 10, the staff only needs to first place the bracket 20 in the accommodating cavity so that the inclined surface of the third plate body 17 and the inclined surface of the second mating portion 21 cooperate, and then press the bracket 20. The surrounding plate is slightly deformed under the action of the pressing force, and the bracket 20 slides along the inclined surface until the second mating portion 21 slides into the recess, and the bracket 20 and the panel 10 are completed with snap connection.

[0057] Optionally, the lock further includes a support structure. Among them, the support structure is arranged on the inner peripheral cavity wall 122 of the accommodating cavity 12, and the support structure is used to support the bracket 20 so that there is a preset gap between the assembled bracket 20 and the cavity bottom wall 121 of the panel 10, and the thickness of the sealing structure 40 is greater than the preset gap. In this way, the above settings make a certain distance between the bracket 20 and the PCB board 50, so that the pits on the bracket 20 can reflect and converge the light emitted by the PCB board 50 to improve the brightness of the digital keys of the touch pad 60. At the same time, the above setting of the thickness of the sealing structure 40 ensures the sealing reliability of the sealing structure 40.

[0058] In this embodiment, the rib away from the substrate has a relatively small cross-section to avoid affecting the snap-fit process between the bracket 20 and the panel 10. When the bracket 20 and the panel 10 are assembled, the support structure supports the bracket 20 to limit the position of the bracket 20, thereby ensuring a preset gap between the bracket 20 and the substrate.

[0059] Embodiment Two

[0060] The difference between the lock in Embodiment Two and that in Embodiment One lies in the different setting positions of the sealing structure 40.

[0061] In this embodiment, the panel 10 has a receiving cavity 12, the first engaging portion 11 is disposed on the bottom wall 121 of the receiving cavity 12, and the sealing structure 40 is located on the outer peripheral surface of the bracket 20 and the inner peripheral wall 122 of the receiving cavity 12. In this way, the above setting makes the structural layout of the sealing structure 40 in the lock more reasonable and compact, improving the space utilization rate inside the lock while ensuring the sealing reliability.

[0062] Optionally, an installation groove is provided on the inner peripheral wall 122, and the sealing structure 40 is bonded or snap-fitted in the installation groove. In this way, the above setting makes the assembly of the sealing structure 40 easier and simpler, reducing the assembly difficulty of the sealing structure 40.

[0063] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0064] The panel and the bracket of the lock are assembled together by combining the stop fit of the first engaging portion and the second engaging portion and the fastening of the fastener, which is not only convenient for the disassembly and assembly of the panel and the bracket, but also improves the connection stability between the two. In this way, the sealing structure is provided between the panel and the bracket to seal the connection between the two, thereby avoiding impurities such as dust from entering the lock through the connection between the two, solving the problem in the prior art that impurities such as dust easily enter the lock through the connection between the bracket and the front panel, and ensuring the normal use of the lock.
