For example, it can mean fixed connection, detachable connection, or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0033] See Figure 1-7 This is an embodiment of the three-point electronic lock of the utility model.

[0034] like Figure 1, including a three-point lock 1, a mounting shell 2 sleeved on the three-point lock 1, and an inner pull module 3 and an outer pull module 4 provided on the mounting shell 2;

[0035] Among them, the external pull module 4 is provided with a password button unlocking mechanism 41, a fingerprint unlocking mechanism 42, an external handle unlocking mechanism 43 and a key unlocking mechanism 44;

[0036] The inner pull module 3 in this device is the unlocking module inside the RV, and the outer pull module 4 is the unlocking module outside the RV; for the unlocking module outside the RV, providing more unlocking methods is a common technical solution in the field, among which this device is provided with a password button unlocking mechanism 41, a fingerprint unlocking mechanism 42, an outer handle unlocking mechanism 43 and a key unlocking mechanism 44; the password button unlocking mechanism 41 and the fingerprint unlocking mechanism 42 make the door opening method more intelligent.

[0037] like Figure 2-7 The present device also improves the installation structure for installing the lock on the RV door. The installation shell 2 includes a base shell 5 with a card slot 6 in the middle. The front end of the base shell 5 is provided with a first mounting plate 7, and the rear end is provided with a second mounting plate 8. The rear end of the first mounting plate 7 is provided with a first mounting tube 9 near the upper end, and the rear end of the first mounting plate 7 is provided with a second mounting tube 10 near the lower end. The first mounting tube 9 and the second mounting tube 10 pass through the second mounting plate 8, and mounting holes are provided in the first mounting tube 9 and the second mounting tube 10; the front end surface of the first mounting plate 7 is provided with a convex ring 11, and card plates 12 are provided on both sides of the convex ring 11.

[0038] In this device, the function of the base shell 5 is to install the three-point lock 1 in the middle of the card slot 6, and at the same time use the card slot 6 to fix the inner pull module 3 and the outer pull module 4 on the mounting shell 2, so that the inner pull module 3 and the outer pull module 4 cooperate with the three-point lock 1.

[0039] The first mounting plate 7 and the second mounting plate 8 are used to fix the base shell 5 on the RV door. Specifically, the first mounting tube 9 and the second mounting tube 10 are provided on the first mounting plate 7 and the second mounting plate 8. When the entire lock structure is assembled, the mounting holes in the first mounting tube 9 and the second mounting tube 10 are aligned with the mounting pins on the RV door, and then the door is locked.

[0040] The convex ring 11 in this device is used to set the clamping plates 12 on both sides. The function of the clamping plates 12 is also to buckle on the fixed buckle plates on the RV door. The purpose is to increase the stability of the entire lock structure and prevent the lock from loosening from the RV door when people use the handle to unlock it.

[0041] The convex ring 11 includes a mounting ring 13 and a mounting block 14 arranged at the upper end of the mounting ring 13. The mounting block 14 is integrally formed with the first mounting plate 7. A first mounting groove 15 is provided in the mounting block 14. The first mounting groove 15 passes through the first mounting plate 7, and the bottom of the first mounting tube 9 is fixed on the mounting block 14.

[0042] The purpose of the mounting block 14 in this device is to set the first mounting groove 15, and the role of setting the first mounting groove 15 is to extend the length of the first mounting tube 9. Extending the length of the first mounting tube 9 means that the depth of the mounting hole increases, and the hole depth means that the tightness when fitting with the mounting pin is stronger.

[0043] A cylindrical ring 16 is provided on the outside of the mounting ring 13 , and a through groove 17 is provided in the mounting block 14 at a lower position thereof, and the cylindrical ring 16 passes through the through groove 17 .

[0044] The mounting ring 13 in this device is made of plastic, which is not very strong. At the same time, the lock body structure is mostly made of metal parts. The thermal expansion and contraction of these metal parts will generate forces on the mounting ring 13. Therefore, a cylindrical ring 16 is provided to restrain the mounting ring 13 and improve the service life of the mounting ring 13.

[0045] In order to prevent the cylindrical ring 16 from being removed by people, a through groove 17 is provided in the mounting block 14, and the through groove 17 is used to lock part of the cylindrical ring 16.

[0046] A third mounting tube 18 is further provided at the rear end of the first mounting plate 7 near the upper end. The third mounting tube 18 passes through the second mounting plate 8 and is provided with a mounting hole therein. The third mounting tube 18 is located below the first mounting tube 9 .

[0047] The third mounting tube 18 of the device is mainly used to strengthen the tight installation of the lock body structure and the RV door.

[0048] A second mounting groove 19 is provided in the mounting ring 13 . The second mounting groove 19 passes through the first mounting plate 7 . The bottoms of the second mounting tube 10 and the third mounting tube 18 are fixed on the mounting ring 13 .

[0049] At the same time, the function of the second mounting groove 19 is the same as that of the first mounting groove 15 mentioned above, both of which are to increase the depth of the mounting holes in the second mounting tube 10 and the third mounting tube 18, except that the depth of the mounting hole in the first mounting tube 9 is greater than the depth of the mounting holes in the second mounting tube 10 and the third mounting tube 18.

[0050] The cylindrical ring 16 is made of corrosion-resistant metal. The cylindrical ring 16 is exposed to the air for a long time and needs to provide a restraining force to the mounting ring 13, so a corrosion-resistant metal material is selected.

[0051] The three-point lock 1 includes a central lock, an upper pull rod is provided at the upper end of the central lock, an upper lock body is provided at the end of the upper pull rod, a lower pull rod is provided at the lower end of the central lock, and a lower lock body is provided at the end of the lower pull rod.

[0052] This is the basic structure of a three-point lock 1, and belongs to the existing technology in the field.

[0053] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
