Description

[0001] The utility model relates to the technical field of door locks, in particular to a door lock compensating transmission mechanism. Background Art

[0002] As an important part of security protection, the stability and reliability of door locks play a vital role in protecting people's property and personal safety. With the continuous development of technology, electronic door locks have gradually replaced traditional mechanical door locks and become the mainstream product on the market. Electronic door locks usually use motors to drive transmission mechanisms to open and lock the lock cylinder. However, existing electronic door locks often have some problems during the transmission process, such as unstable transmission, easy jamming, and inaccurate locking position.

[0003] In the prior art, the transmission mechanism of the electronic door lock usually directly connects the motor and the lock core, and no compensation buffer mechanism is set. When the motor drives the transmission mechanism to rotate, if a jam or increased resistance occurs, the motor and the transmission mechanism are easily subjected to rigid impact, resulting in damage or shortened life. In addition, during the locking process, if the lock core is not rotated to the right position, the prior art often cannot provide effective compensation force to push the lock core to the final locking position, thereby affecting the safety and reliability of the door lock. Utility Model Content

[0010] Preferably, when the primary transmission gear rotates, the first protrusion drives the elastic member to deform and rotate, and the elastic member drives the driven gear to rotate by pushing the second protrusion, thereby driving the secondary transmission gear to rotate.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a door lock compensation transmission mechanism, such as Figure 1-Figure 3 As shown, it includes a motor 1, a primary transmission mechanism 2 and a secondary transmission mechanism 3. The output shaft of the motor 1 drives the primary transmission mechanism 2 to move. An elastic compensation component 4 is installed on one side of the primary transmission mechanism 2. The primary transmission mechanism 2 drives the secondary transmission mechanism 3 to move through the elastic compensation component 4. The primary transmission mechanism 2 includes a primary transmission gear 21, and the secondary transmission mechanism 3 includes a secondary transmission gear 31. The elastic compensation component 4 includes a driven gear 41. The driven gear 41 is coaxially connected with the primary transmission gear 21. An elastic member 45 is installed on the driven gear 41. The primary transmission gear 21 drives the driven gear 41 to rotate through the elastic member 45. The driven gear 41 is meshed with the secondary transmission gear 31. The motor 1 is used as a power source. The motor 1 is responsible for providing driving force so that its output shaft can drive the primary transmission mechanism 2 to move. The primary transmission mechanism 2 is mainly composed of the primary transmission gear 21. When the output shaft of the motor 1 rotates, it directly drives the primary transmission gear 21 to rotate.

[0022] The elastic compensation component 4 is a key part of the entire mechanism. It is installed on one side of the primary transmission mechanism 2 and includes a driven gear 41 and an elastic member 45. The driven gear 41 is coaxially connected to the primary transmission gear 21, which means that when the primary transmission gear 21 rotates, the driven gear 41 will also rotate. However, the connection between them is not rigid, but is achieved through the elastic member 45. The elastic member 45 can be a torsion spring or other elastic element, which allows a certain relative movement between the primary transmission gear 21 and the driven gear 41. When the primary transmission gear 21 rotates, it will first drive the driven gear 41 to deform through the elastic member 45. This deformation actually buffers and compensates for the impact and resistance in the transmission process. Then, the driven gear 41 rotates again under the push of the elastic member 45.

[0023] The secondary transmission mechanism 3 is mainly composed of a secondary transmission gear 31. The driven gear 41 is meshed with the secondary transmission gear 31, so when the driven gear 41 rotates, it drives the secondary transmission gear 31 to rotate. In this way, the primary transmission mechanism 2 successfully drives the movement of the secondary transmission mechanism 3 through the elastic compensation component 4.

[0024] In this embodiment, the output shaft of the motor 1 is equipped with an output gear 11 , and the output gear 11 is meshed with the primary transmission gear 21 , so that the motor 1 drives the primary transmission mechanism 2 to operate.

[0025] Specifically, a lock core transmission member 32 is installed at the axis of the secondary transmission gear 31, which is used to connect the lock core and drive the lock core to realize the opening and closing lock action.

[0026] Furthermore, a shaft 22 is installed at the axis center of the primary transmission gear 21 , and a sleeve 42 is installed at the axis center of the driven gear 41 , and the sleeve 42 is sleeved and matched with the shaft 22 .

[0027] Furthermore, a plurality of first protrusions 23 are installed on one side of the primary transmission gear 21, a plurality of second protrusions 43 are installed on one side of the driven gear 41, a plurality of bayonet holes 44 are provided on the surface of the driven gear 41, the outer end of the first protrusion 23 passes through the bayonet hole 44, the elastic member 45 is an annular structure and is sleeved on the sleeve 42, and levers 451 are installed at both ends of the elastic member 45, and the levers 451 are attached to the outer walls of the first protrusion 23 and the second protrusion 43.

[0028] Furthermore, when the primary transmission gear 21 rotates, the first protrusion 23 drives the elastic member 45 to deform and rotate, and the elastic member 45 drives the driven gear 41 to rotate by pushing the second protrusion 43, thereby driving the secondary transmission gear 31 to rotate.

[0029] Furthermore, the size of the bayonet 44 is larger than that of the first protrusion 23 , so that the first protrusion 23 has a certain amount of space for movement, thereby avoiding the situation of being stuck.

[0030] Furthermore, a baffle 46 is installed on the outer side of the elastic member 45 to protect the elastic member 45 and prevent it from being damaged or falling off.

[0031] When the door lock compensation transmission mechanism of the present invention is used, first when the motor 1 is started, its output shaft will drive the output gear 11 to rotate. The output gear 11 is meshed with the primary transmission gear 21, so the primary transmission gear 21 will also rotate. This process is the initial power source of the transmission mechanism.

[0032] As the primary transmission gear 21 rotates, it drives the secondary transmission mechanism 3 to move through the elastic compensation component 4. The key part of the elastic compensation component 4 is the elastic member 45, which is connected between the primary transmission gear 21 and the driven gear 41. The driven gear 41 is coaxially connected to the primary transmission gear 21, but the connection between them is not rigid, but a flexible connection achieved by the elastic member 45.

[0033] When the primary transmission gear 21 rotates, it first drives the elastic member 45 to deform. This deformation actually buffers and compensates for the impact and resistance during the transmission process. Then, the elastic member 45 uses its elastic restoring force to drive the driven gear 41 to rotate. The driven gear 41 is meshed with the secondary transmission gear 31, so when the driven gear 41 rotates, it drives the secondary transmission gear 31 to rotate.

[0034] A lock core transmission member 32 is installed at the axis of the secondary transmission gear 31. When the secondary transmission gear 31 rotates, the lock core transmission member 32 rotates accordingly, thereby driving the lock core to realize the opening and closing lock action.

[0035] In order to enhance the elastic compensation effect, a plurality of first protrusions 23 are installed on one side of the primary transmission gear 21, and a plurality of second protrusions 43 are installed on one side of the driven gear 41. When the primary transmission gear 21 rotates, the first protrusions 23 drive the elastic member 45 to deform and rotate. A lever 451 is installed at both ends of the elastic member 45, and the lever 451 is attached to the outer wall of the first protrusion 23 and the second protrusion 43. This design enables the elastic member 45 to better transmit torque and achieve compensation buffering.

[0036] In addition, the surface of the driven gear 41 is provided with a plurality of bayonet holes 44, through which the outer end of the first protrusion 23 passes. The size of the bayonet hole 44 is larger than that of the first protrusion 23, and this design is to provide a certain amount of activity space for the first protrusion 23 to avoid being stuck during the transmission process.

[0037] Finally, it should be noted that the electronic components in the motor 1 in this embodiment are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
