[0040] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0041] Please also read Figures 1 to 3The lock handle 10 provided in the embodiment of the present application is mainly used to cooperate with the cam member 30 and the lock housing 20. The lock housing 20 is used to be fixed on the door panel, the cam member 30 is rotatably arranged on the lock housing 20, and the lock handle 10 is installed on the lock housing 20 and is used to drive the cam member 30 to rotate to realize the lock opening and closing operation.

[0042] The lock handle 10 includes a housing 11, an unlocking mechanism 12 and a control assembly 13. The housing 11 includes an ultrasonic welding structure 111 and a first housing 112. The ultrasonic welding structure 111 includes a second housing 1111 and a third housing 1112. The second housing 1111 and the third housing 1112 are ultrasonically welded to enclose and form a first accommodating cavity 1113. At least one of the second housing 1111 and the third housing 1112 is connected to the first housing 112. The unlocking mechanism 12 is disposed in the first housing 112. The control assembly 13 is disposed in the first accommodating cavity 1113, and the control assembly 13 is electrically connected to the unlocking mechanism 12.

[0043] Ultrasonic welding technology refers to a welding technology that uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded, and under pressure, causes the two surfaces to rub against each other to form a fusion between the molecular layers.

[0044] It can be understood that the ultrasonic welding structure 111 is formed by welding the second shell 1111 and the third shell 1112, and the second shell 1111 and the third shell 1112 are enclosed together to form the first accommodating cavity 1113. During installation, the user can install the control component 13 on the second shell 1111 of the ultrasonic welding structure 111, and then weld the third shell 1112 to the second shell 1111 by ultrasonic welding to accommodate the control component 13 in the first accommodating cavity 1113.

[0045] At least one of the second shell 1111 and the third shell 1112 can be connected to the first shell 112 by means of snap connection, bonding, etc.

[0046] Specifically, the unlocking mechanism 12 may include an electronic lock mechanism 121, and the electronic lock mechanism 121 includes a motor and a push rod. The motor of the electronic lock mechanism 121 is electrically connected to the control component 13, so that the control component 13 controls the operation of the motor according to information such as fingerprints and passwords input by the user, and then drives the push rod to move through the motor. As an example, the lock handle 10 also includes a lever rotatably arranged on the first housing 112, and the lever is plugged into the cam member 30. The push rod can be inserted into the lever of the lock handle 10 under the drive of the motor, and the push rod drives the lever to rotate, and then the lever drives the cam member 30 to rotate, so as to realize the switch lock operation.

[0047] Specifically, the control component 13 may include structures such as a circuit board, a controller, and an electrical connector. The control component 13 can be electrically connected to the unlocking mechanism 12 through the electrical connector, and control the movement of the unlocking mechanism 12 through the controller. As an example, the control component 13 can realize information collection functions such as password recognition and fingerprint recognition, and analyze and process the collected information such as fingerprints to control whether the unlocking mechanism 12 unlocks.

[0048] The lock handle 10 provided in the embodiment of the present application, when installed, the user can weld the second housing 1111 and the third housing 1112 together by ultrasonic welding technology, and the second housing 1111 and the third housing 1112 are ultrasonically welded and surrounded to form a first accommodating cavity 1113, and the control component 13 is accommodated in the first accommodating cavity 1113. Then, the ultrasonic welding structure 111 is installed on the first housing 112, and the unlocking mechanism 12 is arranged on the first housing 112 and electrically connected to the control component 13. The second housing 1111 and the third housing 1112 are ultrasonically welded, so that the connection between the second housing 1111 and the third housing 1112 is sealed, so that the first accommodating cavity 1113 can achieve a sealing effect. In this way, the sealing performance of the ultrasonic welding structure 111 is good, and the control component 13 accommodated in the first accommodating cavity 1113 is protected from water, and external water vapor is not easy to enter the first accommodating cavity 1113, which improves the situation that the control component 13 is easily damp and short-circuited, and reduces the risk of damage to the control component 13.

[0049] In some embodiments, the unlocking mechanism 12 may further include a mechanical lock mechanism 122. The mechanical lock mechanism 122 includes a lock core and a push rod. When the key is inserted into the lock core and rotated, the output end of the lock core can push the push rod to move. As an example, the lock handle 10 also includes a lever that is rotatably disposed on the first housing 112, and the lever is plugged into the cam member 30. The push rod is inserted into the lever, and then the lever drives the cam member 30 to rotate, thereby realizing the switch lock operation.

[0050] In some embodiments, see Figures 2 to 4 The first ultrasonic line column 11111 is provided on the four edges of the second shell 1111 facing the third shell 1112. The first ultrasonic line column 11111 is fused to the four edges of the third shell 1112 facing the second shell 1111.

[0051] By having the first ultrasonic line column 11111 contact the edges of the third shell 1112 on one side facing the second shell 1111, the contact area between the second shell 1111 and the third shell 1112 is reduced, which is conducive to better ultrasonic welding of the first ultrasonic line column to the third shell 1112 and better welding effect.

[0052] Alternatively, in another embodiment, a second ultrasonic line column is provided on the four edges of the third shell 1112 facing the second shell 1111. The second ultrasonic line column is fused to the four edges of the second shell 1111 facing the third shell 1112.

[0053] The second ultrasonic line column contacts the four edges of the second shell 1111 facing the third shell 1112, so that the second shell 1111 and the third shell 1112 can be tightly welded. The four edges of the second shell 1111 and the third shell 1112 are ultrasonically welded, thereby improving the sealing performance of the first accommodating cavity 1113.

[0054] Alternatively, in another embodiment, the first ultrasonic line cylinder 11111 is provided on the four edges of the second shell 1111 facing the third shell 1112. The second ultrasonic line cylinder is provided on the four edges of the third shell 1112 facing the second shell 1111. The first ultrasonic line cylinder 11111 is fused to the four edges of the third shell 1112 facing the second shell 1111. The second ultrasonic line cylinder is fused to the four edges of the second shell 1111 facing the third shell 1112, further improving the welding effect between the second shell 1111 and the third shell 1112.

[0055] In some embodiments, see Figures 2 to 4 The ultrasonic welding structure 111 is disposed at one end of the first housing 112 along the first direction X. The ultrasonic welding structure 111 is provided with a slot 1114. The first housing 112 is provided with a plug-in component 1123. The plug-in component 1123 can be inserted into the slot along the second direction Y. The plug-in component 1123 is limited to the groove walls on the opposite sides of the slot 1114 along the first direction X. The first direction X intersects with the second direction Y.

[0056] The intersection of the first direction X and the second direction Y means that the first direction X and the second direction Y may form an angle greater than 0° and less than 180°, that is, the first direction X and the second direction Y are not parallel. The first direction X and the second direction Y may be perpendicular to each other or not perpendicular to each other. The first direction X and the second direction Y may be directions intersecting on the same plane or on planes that are not aligned with each other, and the projection of the second direction Y on the plane where the first direction X is located may intersect with the first direction X.

[0057] As an example, the first direction X is perpendicular to the second direction Y. Figure 2 The direction X shown in the figure, the second direction Y is as follows Figure 2 The direction Y indicated in the figure, Figure 2The direction Z is also indicated in the figure. The directions X, Y and Z are the directions of the three coordinate axes in the space coordinate system, that is, the direction X is perpendicular to the direction Y, the direction X is perpendicular to the direction Z, and the direction Y is perpendicular to the direction Z.

[0058] The first shell 112 is plugged into the ultrasonic welding structure 111, which improves the sealing performance of the first shell 112 and the ultrasonic welding structure 111. External water vapor is not easy to enter the first accommodating cavity 1113 through the connection between the first shell 112 and the ultrasonic welding structure 111, thereby improving the sealing performance of the first accommodating cavity 1113, improving the situation where the control component 13 is easily affected by moisture and short-circuited, and reducing the risk of damage to the control component 13.

[0059] In one embodiment, the first ultrasonic line cylinder 11111 is disposed on one side of the second housing 1111 along the first direction X. Along the first direction X, the third housing 1112 is provided with a first ultrasonic groove (not shown) on all four edges of one side facing the second housing 1111. The first ultrasonic groove is disposed corresponding to the position of the first ultrasonic line cylinder 11111. The first ultrasonic line cylinder 11111 is inserted into the first ultrasonic groove, and the first ultrasonic line cylinder 11111 is fused to the first ultrasonic groove.

[0060] In this way, the first ultrasonic line column 11111 can be inserted into the first ultrasonic groove during installation, which is conducive to better alignment of the second shell 1111 with the third shell 1112. At the same time, the overflow of the first ultrasonic line column 11111 and the groove wall of the first ultrasonic groove during molten welding can be accommodated in the first ultrasonic groove, which improves the overflow during welding and improves the aesthetics and welding reliability of the ultrasonic welding structure 111.

[0061] Alternatively, in another embodiment, the second ultrasonic line column (not shown) is disposed on one side of the third housing 1112 along the first direction X. Along the first direction X, the second housing 1111 is provided with a second ultrasonic groove (not shown) on all four edges of one side facing the third housing 1112. The second ultrasonic line groove is disposed corresponding to the position of the second ultrasonic line column. The second ultrasonic line column is inserted into the second ultrasonic groove and fused with the second ultrasonic groove.

[0062] In this way, the second ultrasonic line column can be inserted into the second ultrasonic groove during installation, which is conducive to better alignment of the second shell 1111 with the third shell 1112. The overflow of the second ultrasonic line column and the groove wall of the second ultrasonic groove during molten welding can be accommodated in the second ultrasonic groove, which improves the overflow during welding and improves the aesthetics and welding reliability of the ultrasonic welding structure 111.

[0063] Alternatively, in another embodiment, the first ultrasonic line cylinder 11111 is provided on one side of the second shell 1111 along the first direction X. Along the first direction X, the third shell 1112 is provided with a first ultrasonic groove on all four edges of one side facing the second shell 1111. The first ultrasonic groove is provided corresponding to the position of the first ultrasonic line cylinder 11111. The first ultrasonic line cylinder 11111 is inserted into the first ultrasonic groove, and the first ultrasonic line cylinder 11111 is fused to the first ultrasonic groove. The second ultrasonic line cylinder is provided on one side of the third shell 1112 along the first direction X. Along the first direction X, the second shell 1111 is provided with a second ultrasonic groove on all four edges of one side facing the third shell 1112. The second ultrasonic line groove is provided corresponding to the position of the second ultrasonic line cylinder. The second ultrasonic line cylinder can be inserted into the second ultrasonic groove and fused to the second ultrasonic groove.

[0064] In this way, the overflow situation during welding of the second shell 1111 and the third shell 1112 is improved. During the welding process, the first ultrasonic line column 11111 and the second ultrasonic line column are respectively inserted into the first ultrasonic groove and the second ultrasonic groove, which is conducive to the mutual alignment of the second shell 1111 and the third shell 1112.

[0065] Along the first direction X, the side of the second shell 1111 facing the third shell 1112 is ultrasonically welded to the side of the third shell 1112 facing the second shell 1111. In one embodiment, see Figures 2 to 5 The third housing 1112 is provided with a first limiting portion 11121 and a second limiting portion 11122. The first limiting portion 11121 and the second limiting portion 11122 are spaced apart in a direction intersecting the first direction X. The opposite side walls of the second housing 1111 are respectively limited at a side of the first limiting portion 11121 away from the second limiting portion 11122 and a side of the second limiting portion 11122 away from the first limiting portion 11121.

[0066] The first limiting portion 11121 and the second limiting portion 11122 may be structures such as convex edges, bumps or columns arranged on the third shell 1112 .

[0067] The distribution direction of the first limiting portion 11121 and the second limiting portion 11122 can be as follows: Figure 2 The direction Z shown can also be Figure 2 The direction Y shown may even be other directions different from the above directions.

[0068] In this way, when the second housing 1111 is installed on the third housing 1112, the opposite side walls of the second housing 1111 can be blocked by the first limiting portion 11121 and the second limiting portion 11122 and cannot move in a direction intersecting the first direction X. The risk of the second housing 1111 shaking relative to the third housing 1112 is reduced, and the installation stability of the second housing 1111 and the third housing 1112 is improved.

[0069] Alternatively, in another embodiment, the third housing 1112 is provided with a third limiting portion 11123 and a fourth limiting portion 11124. The third limiting portion 11123 and the fourth limiting portion 11124 are spaced apart along a direction intersecting the first direction X. The two opposite side walls of the second housing 1111 are respectively limited at opposite sides of the third limiting portion 11123 and the fourth limiting portion 11124.

[0070] The third limiting portion 11123 and the fourth limiting portion 11124 may be structures such as convex edges, bumps or columns arranged on the third shell 1112 .

[0071] When the third shell 1112 is provided with a first limiting portion 11121 and a second limiting portion 11122, the distribution direction of the third limiting portion 11123 and the fourth limiting portion 11124 intersects with the distribution direction of the first limiting portion 11121 and the second limiting portion 11122, and the distribution direction of the third limiting portion 11123 and the fourth limiting portion 11124 and the distribution direction of the first limiting portion 11121 and the second limiting portion 11122 both intersect with the first direction X.

[0072] In this way, when the second housing 1111 is installed on the third housing 1112, the two opposite side walls of the second housing 1111 can be blocked by the third limiting portion 11123 and the fourth limiting portion 11124 and cannot move. This reduces the risk of the second housing 1111 shaking relative to the third housing 1112, and improves the installation stability of the second housing 1111 and the third housing 1112.

[0073] Alternatively, in another embodiment, the third shell 1112 is provided with a first limiting portion 11121 and a second limiting portion 11122 at intervals along a direction intersecting the first direction X. At the same time, along another direction intersecting the first direction X. The third shell 1112 is also provided with a third limiting portion 11123 and a fourth limiting portion 11124 at intervals. The two opposite side walls of the second shell 1111 are respectively limited to the side of the first limiting portion 11121 away from the second limiting portion 11122 and the side of the second limiting portion 11122 away from the first limiting portion 11121. The two opposite side walls of the second shell 1111 are also respectively limited to the opposite sides of the third limiting portion 11123 and the fourth limiting portion 11124. When the second shell 1111 is connected to the third shell 1112, the second shell 1111 can be limited to the third shell 1112 along two directions intersecting each other, and the above two directions both intersect with the first direction X. In this way, the installation stability of the second shell 1111 on the third shell 1112 is improved, and the second shell 1111 and the third shell 1112 are not easy to shake relative to each other.

[0074] Along the first direction X, the side of the second shell 1111 facing the third shell 1112 is ultrasonically welded to the side of the third shell 1112 facing the second shell 1111. In one embodiment, the second shell 1111 is provided with a first positioning member. The third shell 1112 is provided with a first positioning groove. The first positioning member is used to be limited in the first positioning groove along a direction intersecting the first direction X.

[0075] The first positioning member may be, but is not limited to, a structure such as a column or a bump.

[0076] The number of the first positioning members can be selected to be one or more, and the number of the first positioning grooves is set corresponding to the number of the first positioning members.

[0077] By providing the above-mentioned first positioning member and the first positioning groove, the second housing 1111 can be accurately welded to the third housing 1112, thereby improving the positioning effect of the second housing 1111 and the third housing 1112, facilitating the alignment of the second housing 1111 and the third housing 1112 during welding, and improving the assembly accuracy of the third housing 1112 and the second housing 1111. The first positioning member is limited in the first positioning groove, so that relative displacement between the second housing 1111 and the third housing 1112 is not easy to occur.

[0078] Alternatively, in another embodiment, the third housing 1112 is provided with a second positioning member. The second housing 1111 is provided with a second positioning groove. The second positioning member is used to be limited in the second positioning groove along a direction intersecting the first direction X.

[0080] The number of the second positioning members can be selected to be one or more, and the number of the second positioning grooves is set corresponding to the number of the first positioning members.

[0081] By providing the second positioning member and the second positioning groove, the second housing 1111 can be accurately welded to the third housing 1112, thereby improving the positioning effect of the second housing 1111 and the third housing 1112, so that the second housing 1111 and the third housing 1112 can be aligned during welding, thereby improving the assembly accuracy of the second housing 1111 and the third housing 1112. The second positioning member is limited in the second positioning groove, so that the second housing 1111 and the third housing 1112 are not easily displaced relative to each other.

[0082] Alternatively, in another embodiment, the second housing 1111 is provided with a first positioning member and a second positioning groove, and the third housing 1112 is provided with a first positioning groove and a second positioning member. The first positioning member is used to limit the position in the first positioning groove along a direction intersecting the first direction X. The second positioning member is used to limit the position in the second positioning groove along a direction intersecting the first direction X. In this way, the second housing 1111 and the third housing 1112 can be better aligned during welding, and relative displacement is not likely to occur.

[0083] In some embodiments, see Figure 2 and Figure 3 The ultrasonic welding structure 111 and the first shell 112 are arranged to form a second accommodating cavity 113. At least part of the unlocking mechanism 12 is accommodated in the second accommodating cavity 113. The third shell 1112 is provided with a wire hole 11125. The wire hole 11125 is used for passing the wire between the unlocking mechanism 12 and the control assembly 13.

[0084] The number of the wire holes 11125 can be one or more.

[0085] As an example, the control component 13 has a plug, which is exposed in the wire hole 11125. The unlocking mechanism 12 has a cable, which can pass through the wire hole 11125 to be electrically connected to the plug of the control component 13. Alternatively, the control component 13 has a cable, and the unlocking mechanism 12 has a connector. The cable of the control component 13 can pass through the wire hole 11125 and be plugged and electrically connected to the plug of the unlocking mechanism 12.

[0086] In this way, the first accommodating cavity 1113 and the second accommodating cavity 113 are connected through the wire hole 11125, and moisture is not easy to enter the first accommodating cavity 1113 through the wire hole 11125, thereby improving the waterproof effect of the first accommodating cavity 1113, making the electrical connection between the unlocking mechanism 12 and the control component 13 safer and more reliable, and reducing the risk of the control component 13 being damaged by moisture.

[0087] In some embodiments, see Figure 5The ultrasonic welding structure 111 is disposed at one end of the first shell 112 along the first direction X. The lock handle 10 further includes a battery cover 15. The battery cover 15 is disposed at one end of the first shell 112 away from the ultrasonic welding structure 111 along the first direction X. The battery cover 15 and the third shell 1112 are surrounded to form a battery compartment 16. The battery compartment 16 is used to accommodate the battery 14.

[0088] The battery 14 is contained in the battery compartment 16 and covered by the battery cover 15. The battery cover 15 can provide waterproof protection for the battery 14 in the battery compartment 16, so that moisture is not easy to enter the battery compartment 16 through the battery cover 15, thereby improving the safety of the battery 14. In addition, the battery 14 in the battery compartment 16 can be replaced and repaired by removing the battery cover 15, thereby improving the convenience of repairing the battery 14.

[0089] In some embodiments, see Figures 5 to 7 , the first shell 112 is provided with a first hook 1121. The battery cover 15 is provided with a second hook 151. The second hook 151 hooks the first hook 1121 in a direction away from the ultrasonic welding structure 111 along the first direction X. The first shell 112 is provided with a limiting column 1122. The second hook 151 is limited between the limiting column 1122 and the first hook 1121 along the third direction Z. The first direction X intersects with the third direction Z.

[0090] In this way, the connection strength between the first shell 112 and the battery cover 15 is improved, the battery cover 15 is not easily separated from the first shell 112, and the installation firmness of the battery 14 in the battery compartment 16 is improved.

[0091] According to the lock of the second embodiment of the present application, the lock comprises a lock housing 20, a cam member 30 and a lock handle 10 of the first embodiment of the present application. The cam member 30 is mounted on the lock housing 20. The housing 11 is plugged into the lock housing 20. The unlocking mechanism 12 is used to drive the cam member 30 to rotate.

[0092] Among them, the lock handle 10 involved in the embodiment of the present application is the same as the lock handle 10 involved in the above embodiment. For details, please refer to the relevant description above and will not be repeated here.

[0093] It should be noted that the lock housing 20 is used to be installed on the door panel, and the cam member 30 is installed on the lock housing 20 and can rotate in the lock housing 20. During use, the user can drive the unlocking mechanism 12 to work by inserting a key, entering a password, etc., so that the unlocking mechanism 12 can drive the cam member 30 in the lock housing 20 to rotate, so as to realize the lock opening and closing operation.

[0094] The lock provided in the embodiment of the present application has an ultrasonic welding structure 111 in the lock handle 10 of the lock, and the ultrasonic welding structure 111 eliminates the assembly gap. When the control component 13 is located in its first accommodating cavity 1113, moisture is not easy to enter the first accommodating cavity 1113, which further reduces the risk of short circuit and damage of the control component 13 and improves the service life and reliability of the lock.

[0095] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
