Abstract
Description
Technical Field
[0001] This utility model relates to a seat floor lock, and more specifically, it relates to a seat floor lock with a reminder function. Background Technology
[0002] A seat floor lock is a locking device embedded in a support surface, commonly used to secure car seats or child safety seats. It aims to improve installation convenience and safety. For ease of use, an additional reminder structure is often added to provide the user with reminders of the lock's unlocked and locked status, preventing accidental unlocking and potential safety hazards. However, in practice, due to cost considerations, the reminder structure is often an independent component, optional for users. This can lead to discrepancies between the lock's unlocked and locked status and the status indicated by the reminder structure. Therefore, a seat floor lock with a built-in reminder function is needed. This device directly integrates the reminder structure with the lock body structure, reducing manufacturing costs while ensuring the accuracy of the reminder function.
[0003] For the reasons mentioned above, how to combine the reminder structure with the lock body structure is the problem that this application addresses. Utility Model Content
[0004] To address the shortcomings of existing technologies, a seat lock with a reminder function is provided. This device directly integrates the reminder structure with the lock body structure, reducing manufacturing costs while ensuring the accuracy of the reminder function.
[0005] To achieve the above objectives, the following technical solution is provided: a seat lock with a reminder function, comprising a mounting shell, a reminder component, a locking component, a lock body torsion spring, and a lock body component. Both the locking component and the lock body component are rotatably mounted on the mounting shell. The locking component is used to restrict the unlocking of the lock body component. The two ends of the lock body torsion spring are respectively connected to the mounting shell and the lock body component. The lock body torsion spring is used to cooperate with the lock body component to drive the lock body component to unlock. The reminder component is mounted on the mounting shell.
[0006] When the locking component restricts the unlocking of the lock body component, the locking component connects to the reminder component, and the reminder component sends a signal.
[0007] In summary, the above technical solution has the following beneficial effects: Locking components are usually used indirectly to control the lock body components to achieve unlocking or locking functions. Common locking components use irregularly shaped parts to rotate in order to prevent the lock body components from not being in place. Considering the shortest distance from a fixed point to the part, this shortest distance will change when the part rotates, thus providing a detection basis for the additional reminder structure. However, for the purpose of convenient installation and ensuring safety, the additional reminder structure cannot be tightly connected to the locking component. This utility model directly installs the reminder component on the mounting shell, which can reduce compatibility issues. No additional debugging interface is required during installation and use, and it can be used quickly. Moreover, the reminder component is installed close to the locking component, which has strong anti-interference ability. The resulting distance change can be directly reflected in the reminder component without relying on an additional transmission structure to transmit information. At the same time, from an overall perspective, it reduces the actual number of components needed and reduces the risk of failure due to aging or wear.
[0008] From the perspective of usage cost, the unit cost of this invention is usually lower than the total cost of the "seat lock + external reminder structure" mode. Furthermore, by integrating the components, the complexity of later maintenance is reduced. During installation, there is no need to modify the existing seat lock or add brackets, saving labor and matching accessory costs.
[0009] In addition, this utility model hides the reminder component inside the seat lock, avoiding the abruptness of the external structure and also avoiding the risk of the external structure being easily disassembled or damaged by human intervention, thus improving security through structural encapsulation;
[0010] This utility model sets up a reminder component and a locking component that are linked. The locking component simultaneously controls the complete locking and provides a reminder, thereby directly combining the reminder structure with the lock body structure, reducing manufacturing costs while ensuring the accuracy of the reminder function.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0020] Reference Figure 1-2 As shown, a seat lock with a reminder function includes a mounting shell 1, a reminder component 2, a locking component 3, a lock body torsion spring 4, and a lock body component 5. Both the locking component 3 and the lock body component 5 are rotatably mounted on the mounting shell 1. The locking component 3 is used to restrict the unlocking of the lock body component 5. The two ends of the lock body torsion spring 4 are respectively connected to the mounting shell 1 and the lock body component 5. The lock body torsion spring 4 is used to cooperate with the lock body component 5 to drive the lock body component 5 to unlock. The reminder component 2 is mounted on the mounting shell 1.
[0021] When the locking component 3 restricts the unlocking of the lock body component 5, the locking component 3 is connected to the reminder component 2, and the reminder component 2 sends a signal.
[0022] Locking component 3 is usually used indirectly to control lock body component 5 to achieve unlocking or locking functions. In order to prevent the lock body component 5 from not being in place when the common locking component 3 rotates, an irregularly shaped part is selected to rotate. Considering the shortest distance from a certain fixed point to the part, the shortest distance will change when the part rotates, thus providing a detection basis for the additional reminder structure. However, for the purpose of convenient installation and ensuring safety, the additional reminder structure cannot be tightly connected to the locking component 3. This utility model directly installs the reminder component 2 on the mounting shell 1, which can reduce compatibility issues. No additional interface debugging is required during installation and use, and it can be used quickly. Moreover, the reminder component 2 is installed close to the locking component 3, which has strong anti-interference ability. The resulting distance change can be directly reflected in the reminder component 2 without relying on an additional transmission structure to transmit information. At the same time, from the overall perspective, the actual required parts are reduced, reducing the risk of failure due to aging or wear.
[0023] From the perspective of usage cost, the unit cost of this invention is usually lower than the total cost of the "seat lock + external reminder structure" mode. Furthermore, by integrating the components, the complexity of later maintenance is reduced. During installation, there is no need to modify the existing seat lock or add brackets, saving labor and matching accessory costs.
[0024] In addition, this utility model hides the reminder component 2 inside the seat lock, avoiding the abruptness of the external structure and also avoiding the risk of the external structure being easily disassembled or damaged by human intervention, thus improving security through structural encapsulation;
[0025] This utility model sets the reminder component 2 and the locking component 3 to work together. The locking component 3 simultaneously controls the complete locking and provides a reminder, thereby directly combining the reminder structure with the lock body structure, reducing manufacturing costs while ensuring the accuracy of the reminder function.
[0026] Furthermore, the reminder component 2 includes a support housing 21, a micro switch 22, and a signal transmission line 23. The support housing 21 is mounted on the mounting housing 1, the micro switch 22 is mounted on the support housing 21, and the mounting points of the micro switch 22 and the support housing 21 are far away from the mounting points of the support housing 21. The signal transmission line 23 is connected to the micro switch 22 and is used to transmit reminder signals.
[0027] Furthermore, the mounting shell 1 is provided with a first mounting hole 11 and a second mounting hole 12, and the support shell 21 is provided with a round hole 211 and an oblong hole 212. The round hole 211 is provided corresponding to the first mounting hole 11, and the oblong hole 212 is provided corresponding to the second mounting hole 12.
[0028] The round hole 211 and the first mounting hole 11 are mounted together through the same mounting component, thereby achieving the effect of directly fixing the mounting shell 1 to the support shell 21. The oblong hole 212 and the second mounting hole 12 are mounted together through the same mounting component, and the oblong hole 212 absorbs the lateral tolerance.
[0029] Furthermore, the locking assembly 3 includes a stop hook 31, which is used to cooperate with the lock body assembly 5 to achieve the unlocking function.
[0030] Furthermore, the locking assembly 3 also includes an abutment 32, which is fixedly connected to the stop hook 31. The abutment 32 is used to abut the micro switch 22, and the abutment 32 is arc-shaped towards the micro switch 22.
[0031] To avoid the contact member 32 from colliding with the side of the micro switch 22, the contact member 32 is arranged in an arc shape facing the side of the micro switch 22, so as to guide the micro switch 22 to smoothly collide with the contact member 32 and be triggered.
[0032] Furthermore, the locking assembly 3 also includes a protective sleeve 33, which covers the contact member 32, and the contact member 32 contacts the micro switch 22 through the protective sleeve 33.
[0033] Since the contact element 32 is usually made of metal and constantly separates from and contacts the micro switch 22, both the micro switch 22 and the contact element 32 are prone to wear. Therefore, a protective sleeve 33 is provided as the contact medium. The protective sleeve 33 can be made of inexpensive plastic. The sleeve can be replaced according to the degree of wear or according to the actual distance between the micro switch 22 and the contact element 32. This prevents the micro switch 22 from being unable to be activated due to wear or insufficient distance.
[0034] Furthermore, the protective sleeve 33 and the stop hook 31 form a groove 34. The locking assembly 3 also includes a stop torsion spring 35. The two ends of the stop torsion spring 35 abut against the mounting shell 1 and the inner wall of the groove 34, respectively. The stop torsion spring 35 is used to drive the stop hook 31 to abut against the lock body assembly 5 and restrict the lock body assembly 5 from unlocking.
[0035] Furthermore, the mounting housing 1 is fixedly connected to a first rotating shaft 13 and a second rotating shaft 14. The first rotating shaft 13 is used to install the lock body assembly 5, the stop torsion spring 35 is sleeved on the second rotating shaft 14, and the stop hook 31 is rotatably connected to the second rotating shaft 14.
[0036] Furthermore, the lock body assembly 5 includes a lock leaf 51, and the end of the lock body torsion spring 4 away from the mounting shell 1 abuts against the lock leaf 51. The lock leaf 51 is used to realize the unlocking and locking functions, and the stop hook 31 is used to cooperate with the lock leaf 51 to realize the unlocking function.
[0037] Furthermore, the lock body torsion spring 4 is sleeved on the first rotating shaft 13, and the lock leaf 51 is rotatably connected to the first rotating shaft 13.
[0038] Both the lock body torsion spring 4 and the stop torsion spring 35 are fixed to the mounting shell 1, making the overall structure simpler and lighter, but the functions can be fully covered. The stop hook 31 and the lock leaf 51 are the core structures. With the meshing of the stop torsion spring 35 and the lock body torsion spring 4, the unlocking and locking functions can be realized. Since the stop torsion spring 35 also needs to directly control the micro switch 22 through the abutment 32, the abutment 32 and the stop hook 31 form a groove 34. In this way, one end of the stop torsion spring 35 is accommodated in the groove 34, which can prevent the stop torsion spring 35 from detaching and causing the reminder function to fail.
[0039] The mounting housing 1, the first rotating shaft 13, and the second rotating shaft 14 form the main external frame of the lock body. The two rotating shafts mainly serve as the rotation centers of the stop hook 31 and the lock leaf 51. During installation, calculations need to be performed on the stop hook 31 and the lock leaf 51 respectively, so as to design matching stop torsion spring 35 and lock body torsion spring 4 to provide the necessary torque.
[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
