A door lock assembly 100 according to an embodiment of the present invention, which can be used in a home appliance, is described below with reference to fig. 1 to 4.
As shown in fig. 1 to 4, a door lock assembly 100 according to an embodiment of the present invention includes: a door lock box 1 and a lock catch 5.
Specifically, the door lock case 1 includes a housing 11, a connecting shaft assembly 2, two locking teeth 3 and an elastic member 4, wherein the housing 11 has an opening 11a, and two opposite inner side walls of the housing 11 far away from the opening 11a are respectively provided with a limit groove 11b, and two ends of the connecting shaft assembly 2 are respectively movably matched with the limit grooves 11 b. It can be seen that the connecting shaft assembly 2 is movable relative to the limiting groove 11b, that is, the connecting shaft assembly 2 can move within a certain range in the housing 11. The limiting groove 11b and the opening 11a on the housing 11 are located on different walls of the housing 11. As shown in fig. 1 and 4, for example, the opening 11a is located on the top wall of the housing 11, and the limit grooves 11b are located on the front side wall and the rear side wall of the housing 11, respectively.
Each of the locking teeth 3 is rotatably fitted to the connection shaft assembly 2, respectively, and each of the locking teeth 3 has a locking portion 31, the locking portion 31 being disposed opposite to the opening 11 a. That is, the locking step 31 may protrude out of the housing 11 through the opening 11a, or in the up-down direction, the locking portion 31 may be located within the housing 11 with the locking portion 31 located directly below the opening 11a, or the locking portion 31 may be located at the opening 11a of the housing 11. Meanwhile, since each locking tooth portion 3 is matched with the connecting shaft assembly 2 and is rotatable relative to the connecting shaft assembly 2, the connecting shaft assembly 2 is movable relative to the limiting groove 11b, and accordingly, the locking tooth portion 3 can also move within a certain range relative to the housing 11.
The elastic member 4 is used to drive the two locking portions 3 to rotate to move the two locking portions 31 toward each other. That is, in the case where the locking tooth portion 3 is not subjected to other external force, the locking tooth portion 3 is rotated by the elastic force of the elastic member 4 to move the two locking portions 31 toward each other. When the locking tooth portion 3 receives an external force having a direction opposite to that of the elastic force provided by the elastic member 4 and the external force is greater than the elastic force of the elastic member 4, the locking tooth portion 3 rotates against the elastic force under the external force to move the two locking portions 31 in a direction away from each other, so that the distance between the two locking portions 31 can be increased.
The lock catch 5 has an engaging portion 51, and the engaging portion 51 has a locking position between which the lock catch 5 is movable and a release position in which the engaging portion 51 passes from between the outer ends of the two locking portions 31 at the opening 11a to lock the lock catch 5 to the door-lock case 1.
In summary, when the engaging portion 51 moves from the disengaged position to the locked position, the engaging portion 51 needs to engage with the two locking portions 31 to overcome the elastic force of the elastic member 4 to rotate the locking portions 3, so that the two locking portions 31 move away from each other to increase the distance between the two locking portions 31, and the engaging portion 51 can pass through between the outer ends of the two locking portions 31 and enter the space defined by the inner ends of the two locking portions 31. When the engaging portion 51 enters the inner ends of the two locking portions 31, the locking tooth portion 3 rotates reversely under the elastic force of the elastic member 4 to move the two locking portions 31 toward each other to reduce the distance between the two locking portions 31, so that the locking of the lock catch 5 in the door lock case 1 can be ensured to realize the door locking function of the door lock assembly 100.
When the engaging portion 51 is moved from the locking position to the releasing position, the engaging portion 51 still needs to be engaged with the two locking portions 31 to overcome the elastic force of the elastic member 4 to rotate the locking portions 3, so that the two locking portions 31 move in a direction away from each other to increase the distance between the two locking portions 31, and then the engaging portion 51 can pass between the inner ends of the two locking portions 31 to leave the space defined by the inner ends of the two locking portions 31, and further the engaging portion 51 moves to the outer end of the locking portions 3 to be released from engagement with the locking portions 3, whereby the door opening function of the door lock assembly 100 can be achieved.
As can be seen from the above, in the door lock assembly 100 according to the embodiment of the present invention, the engaging portion 51 of the lock catch 5 is engaged with the locking portion 31 of the locking tooth portion 3, so that the door opening function and the door locking function of the door lock assembly 100 can be realized.
It will be appreciated that since the connecting shaft assembly 2 is moveable relative to the housing 11 to a certain extent, i.e. the locking tooth 3 is moveable relative to the housing 11 to a certain extent. Therefore, when the household appliance applying the door lock assembly 100 of the embodiment of the invention cannot be completely centered and has a certain amount of deflection and dislocation after long-term use, the locking tooth part 3 can move a certain distance in the shell 11 to offset the deflection and dislocation, so that the door lock assembly 100 has a certain self-adaptability, and the locking tooth part 3 can still be normally and stably matched with the matching part 51 of the lock catch 5, thereby realizing the door locking function of the door lock assembly 100. The reliability and stability of the door lock assembly 100 are improved, and the service life of the door lock assembly 100 can be improved to some extent. Meanwhile, the user does not need to use larger force to open the door, so that it can be known that the door lock assembly 100 of the embodiment of the invention can also improve the comfort of the user in using the household appliance applying the door lock assembly 100 and improve the use feeling of the user.
According to the door lock assembly 100 of the embodiment of the invention, by arranging the two locking teeth 3 and the connecting shaft assembly 2 in the door lock box 1, each locking tooth 3 is respectively and rotatably matched with the connecting shaft assembly 2, and the two opposite inner side walls of the shell 11 far away from the opening 11a are respectively provided with the limiting grooves 11b, so that the two ends of the connecting shaft assembly 2 are respectively and movably matched with the limiting grooves 11b, thereby ensuring the normal door opening function and the door locking function of the door lock assembly 100, simultaneously ensuring that the household appliance applying the door lock assembly 100 can ensure that after long-term use, when the door cannot be completely centered and has a certain amount of deflection and dislocation, the locking teeth 3 and the matching parts 51 of the lock catches 5 can still be normally and stably matched, the reliability and the stability of the door lock assembly 100 are improved, the door lock assembly 100 has a certain self-adaptability, the service life of the door lock assembly 100 can be prolonged to a certain extent, a user does not need to use larger force to open the door, and the use feeling of the user is improved.
According to some embodiments of the present invention, one side surface of the two locking parts 31 facing each other has a first mating surface 31a and a second mating surface 31b, respectively, the first mating surface 31a of each locking part 31 is located at an outer end of the second mating surface 31b, the two first mating surfaces 31a extend obliquely in a direction away from each other, the two second mating surfaces 31b extend obliquely in a direction approaching each other, respectively, in a direction from inside to outside, and the two second mating surfaces 31b define the locking position.
The engaging portion 51 has a third engaging surface 51a and a fourth engaging surface 51b on the side corresponding to each locking portion 31, respectively, the third engaging surface 51a being located on the outer side of the fourth engaging surface 51b, two third engaging surfaces 51a extending obliquely toward each other and two fourth engaging surfaces 51b extending obliquely away from each other in the inside-out direction.
When the engaging portion 51 moves from the disengaged position to the locked position, the two fourth engaging surfaces 51b are respectively stopped against the corresponding first engaging surfaces 31a to deform the elastic member 4. That is, when the engaging portion 51 moves from the disengaged position to the locked position, since the third engaging surface 51a of the engaging portion 51 is located outside the fourth engaging surface 51b, the first engaging surface 31a is located at the outer end of the second engaging surface 31b, so that under the action of external force (e.g., a user pushing the door handle), the two fourth engaging surfaces 51b of the engaging portion 51 are first engaged with the first engaging surfaces 31a of the two locking portions 31, respectively, i.e., each fourth engaging surface 51b is stopped against the corresponding first engaging surface 31a and moves from outside to inside to overcome the elastic force of the elastic member 4, so that the elastic member 4 is deformed, the locking tooth portion 3 rotates to move the two locking portions 31 in a direction away from each other to increase the distance between the two locking portions 31, thereby gradually allowing the engaging portion 51 to enter the inner ends of the two locking portions 31.
When the fourth mating surface 51b is completely disengaged from the first mating surface 31a, the third mating surface 51a gradually abuts against the corresponding second mating surface 31b to move inward along the second mating surface 31b, at this time, the elastic member 4 gradually returns to deformation so that the two locking portions 31 gradually move toward each other to reduce the distance between the two locking portions 31, and finally the mating portion 51 of the lock catch 5 is locked in the door lock case 1, thereby realizing the door locking function of the door lock assembly 100.
When the engaging portion 51 moves from the locking position to the releasing position, the two third engaging surfaces 51a respectively abut against the corresponding second engaging surfaces 31b to deform the elastic member 4. That is, when the engaging portion 51 moves from the locking position to the releasing position, since the third engaging surface 51a of the engaging portion 51 is located outside the fourth engaging surface 51b, the first engaging surface 31a is located at the outer end of the second engaging surface 31b, so that under the action of external force (e.g., a user pulls a door handle), the two third engaging surfaces 51a of the engaging portion 51 are first engaged with the second engaging surfaces 31b of the two locking portions 31, respectively, i.e., each of the third engaging surfaces 51a is stopped against the corresponding second engaging surface 31b and moves from inside to outside to overcome the elastic force of the elastic member 4, so that the elastic member 4 is deformed, the locking tooth portion 3 rotates to move the two locking portions 31 in a direction away from each other to increase the distance between the two locking portions 31, thereby gradually releasing the engaging portion 51 from the inner ends of the two locking portions 31.
When the third mating surface 51a and the second mating surface 31b are completely disengaged, the fourth mating surface 51b gradually abuts against the corresponding first mating surface 31a to move outwards along the first mating surface 31a, at this time, the elastic member 4 gradually returns to deformation so that the two locking portions 31 gradually move towards each other to reduce the distance between the two locking portions 31, and finally the mating portion 51 of the lock catch 5 penetrates out of the outer ends of the two locking portions 31 to be disengaged from the locking teeth 3, even if the lock catch 5 is disengaged from the door lock case 1, thereby achieving the door opening function of the door lock assembly 100.
Optionally, the first mating surface 31a is connected to the corresponding second mating surface 31b and the connection is in a circular arc transition. Therefore, the matching part 51 of the lock catch 5 can be effectively prevented from being invalid due to long-term scratching of the edge angle of the connecting part of the first matching surface 31a and the corresponding second matching surface 31b when moving between the locking position and the disengaging position, and the reliability of the door lock assembly 100 can be improved, so that the service life of the door lock assembly 100 can be prolonged.
Alternatively, the ends of the two locking portions 31 facing each other are provided with guide surfaces 31c, the guide surfaces 31c being connected to the respective first and second mating surfaces 31a, 31b, the direction of extension of the guide surfaces 31c being perpendicular to the direction of movement of the two locking portions 31. That is, the guide surface 31c extends along the moving direction of the engaging portion 51, so that the guide surface 31c has a certain guiding function, so that the engaging portion 51 can be moved between the locking position and the releasing position, and the reliability of the door lock assembly 100 can be improved.
Specifically, the connecting shaft assembly 2 is one connecting shaft 21, and the two locking teeth 3 are respectively connected to the connecting shafts 21. Therefore, the connecting shaft assembly 2 has simple structure, convenient manufacture and low cost. Meanwhile, the locking tooth part 3 can be guaranteed to rotate relative to the connecting shaft assembly 2, and the connecting shaft 21 can be guaranteed to move relative to the limiting groove 11 b.
Specifically, the connection shaft 21 is a pin shaft. So that the structure of the connecting shaft 21 is simple and the cost is low. At the same time, the reliability and stability of the connection of the locking tooth 3 with the connecting shaft 21 can be ensured.
Alternatively, as shown in fig. 1-2, two locking teeth 3 are arranged crosswise and each locking tooth 3 is connected to a connecting shaft 21 at the intersection of the two locking teeth 3.

The setting mode of the tooth locking part 3 is simple and reliable.
Alternatively, as shown in fig. 3 to 4, two locking teeth 3 are disposed substantially in parallel and opposite each other, and a connecting shaft 21 is connected to the middle of each locking tooth 3. As can be seen from this, when the two locking portions 31 are moved in the direction away from each other, the ends of the two locking portions 3 away from the respective locking portions 31 are moved in the direction toward each other, and when the two locking portions 31 are moved in the direction toward each other, the ends of the two locking portions 3 away from the respective locking portions 31 are moved in the direction away from each other.
Specifically, each of the locking teeth 3 is provided with an assembly hole 32, and the connecting shaft 21 passes through both assembly holes 32. So that the connection mode of the locking tooth part 3 and the connecting shaft assembly 2 is simple, and the assembly of the door lock assembly 100 is convenient.
Specifically, the housing 11 is provided with a first positioning groove 111 and a second positioning groove 112, and one ends of the two locking tooth parts 3, which are far away from the respective locking parts 31, are respectively located in the first positioning groove 111 and the second positioning groove 112. Therefore, the position of the locking tooth part 3 in the shell 11 can be positioned, the locking tooth part 3 is prevented from moving randomly under the action of the elastic piece 4, the matching reliability of the locking part 31 and the matching part 51 is guaranteed, and the reliability of the door lock assembly 100 is further improved.
Further, a third positioning groove 113 is further provided in the housing 11, and the elastic member 4 is provided in the third positioning groove 113. So that the position of the elastic member 4 within the housing 11 can be positioned, thereby improving the reliability of the door lock assembly 100.
According to some embodiments of the invention, the elastic member 4 is connected between the ends of the two locking teeth 3 remote from the locking portion 31. Since the two locking teeth 3 are rotatably fitted to the connection shaft assembly 2, and the elastic member 4 serves to drive the two locking teeth 3 to rotate so that the two locking portions 31 are moved toward each other. Therefore, according to the lever principle, the elastic member 4 is arranged at the position, so that the utilization rate of the elastic force provided by the elastic member 4 can be improved in the limited space of the door lock box 1, and the energy loss is reduced.
Specifically, the elastic member 4 is a spring. Thereby not only guaranteeing the reliability of the elastic piece 4, but also simplifying the structure of the elastic piece 4, reducing the manufacturing cost of the door lock assembly 100 and facilitating the replacement.
According to some embodiments of the invention, the movement direction of the connecting shaft 21 is perpendicular to the movement direction of the shackle 5. So that the adaptation of the door lock assembly 100 can be further improved.
