Description

Technical Field

[0001] This utility model relates to the field of smart floor locks, and in particular to a driven end flip limiter for smart floor locks. Background Technology

[0002] Smart floor locks typically include a drive unit, a rotating shaft, and a baffle. The drive unit drives the rotating shaft to rotate, and the rotating shaft is fixed to the baffle, thereby realizing the lifting and lowering function of the baffle.

[0003] For example, Chinese patent application number 202221726387.5 discloses a microcontroller-based intelligent control floor lock. The floor lock structure includes a base, a drive device, a drive rod, a baffle, and multiple roller components. The drive device is mounted on the base, and its output end is connected to the drive rod. The roller components include a roller body and multiple balls. The balls are disposed on the roller body, which is sleeved on the outer circumference of the shaft. The balls abut against the outer circumferential wall of the shaft and roll between the roller body and the shaft. In the floor lock structure of the aforementioned patent, the drive rod is equivalent to a rotating shaft. By connecting the output end of the drive device to the drive rod, the rotation of the output end of the drive device drives the drive rod to rotate, thereby causing the baffle fixed on the drive rod to flip, achieving the lifting and lowering function of the baffle.

[0004] However, when using the smart control floor lock provided by the above-mentioned patent, using only the drive device to control the rotation of the baffle can easily lead to excessive rotation of the baffle, making it difficult to control the flip angle of the baffle and preventing the baffle from stopping in the appropriate position, thereby affecting the use of the floor lock function. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a driven end flip limiter for intelligent floor locks, which solves the problem that existing technologies that only use a drive device to control the rotation of the baffle can easily lead to excessive rotation of the baffle, making it difficult to control the flip angle of the baffle and preventing the baffle from stopping at a suitable position, thus affecting the use of the floor lock function. This invention limits the baffle and keeps it at a suitable flip angle.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a driven end flip limiter for a smart floor lock, including a limiter body; the limiter body is plate-shaped; if the limiter body is vertically arranged, a shaft hole is provided through the front plate surface to the rear plate surface of the limiter body for the rotating shaft of the smart floor lock to pass through; an extension is provided at the left end of the limiter body; the distance from the center of the shaft hole to the edge of the limiter body is less than the distance from the center of the shaft hole to the end of the extension.

[0008] The driven end flip limiter for the smart floor lock provided by this utility model preferably has an arc-shaped edge on the limiter body; the side of the extension adjacent to the limiter body is straight; and the side of the extension is tangent to the side of the limiter body.

[0009] The driven end flip limiter for the smart floor lock provided by this utility model preferably has a square vertical cross-section in the front-to-back direction of the shaft hole.

[0010] The driven end flip limiter for the smart floor lock provided by this utility model preferably has arc-shaped grooves on the inner walls of both sides of the shaft hole; the openings of the two arc-shaped grooves are arranged facing each other.

[0011] The above technical solution has the following advantages or beneficial effects:

[0012] This utility model provides a driven end flip limiter for a smart lock, comprising a limiter body, in which the rotating shaft of the smart lock is sleeved within a shaft hole, allowing the limiter body to be fixed to the rotating shaft. This enables the limiter body to rotate with the rotating shaft, maintaining the same rotation angle as the shaft. Furthermore, to control the rotation angle of the rotating shaft, an extension is provided at the left end of the limiter body, such that the distance from the center of the shaft hole to the edge of the limiter body is less than the distance from the center of the shaft hole to the end of the extension. This ensures that when a gap exists between the limiter body and the base after it is installed on the rotating shaft, the rotation of the shaft does not affect the rotation of the limiter body, while the extension can contact the base, thus preventing the shaft from continuing to rotate. Even further, to control the rotation of the smart lock's baffle to a suitable angle, a gap is created between the extension and the baffle... By increasing or decreasing the angle difference between the extension and the baffle, the flipping angle or lifting height of the baffle can be controlled. Furthermore, when a vehicle drives over the smart lock with the baffle raised, the vehicle chassis is prone to scraping against the top of the baffle. At this time, the baffle is prone to continue flipping under force. When the baffle stops, the drive device is stationary. The baffle continues to flip, causing the rotating shaft to rotate. The rotating shaft causes the output shaft of the drive device to rotate. If the instantaneous rotational force of the rotating shaft is too large, it can easily cause the drive device to be damaged by force. Fixing the driven end flipping limiter of the smart lock provided by this utility model on the rotating shaft can transfer the force on the baffle to the base of the smart lock, thereby avoiding the force on the baffle being directly transferred to the output shaft of the drive device, preventing the drive device from being damaged by force, reducing the loss of the smart lock due to scraping by the vehicle base, and extending the service life of the smart lock.

[0013] In the prior art, using only a drive device to control the rotation of the baffle can easily lead to excessive rotation of the baffle, making it difficult to control the flip angle of the baffle and preventing the baffle from stopping at a suitable position, thus affecting the use of the floor lock function. The driven end flip limiter for the smart floor lock provided by this utility model has an extension at the left end of the limiter body. The extension contacts the base of the smart floor lock, thereby controlling the baffle to stop at a suitable flip angle and improving the stability of the baffle flip function in the smart floor lock.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0019] Example 1:

[0020] like Figure 1 As shown, Embodiment 1 of this utility model provides a driven end flip limiter for a smart floor lock, including a limiter body 1; the limiter body 1 is plate-shaped; if the limiter body 1 is vertically arranged, a shaft hole 11 is provided through the front plate surface to the rear plate surface of the limiter body 1 for the rotating shaft of the smart floor lock to pass through; an extension 2 is provided at the left end of the limiter body 1; the distance from the center of the shaft hole 11 to the edge of the limiter body 1 is less than the distance from the center of the shaft hole 11 to the end of the extension 2.

[0021] like Figure 3As shown, when using the driven end flip limiter for the smart lock provided in Embodiment 1 of this utility model, the rotating shaft of the smart lock is sleeved in the shaft hole 11 and fixed to the shaft hole 11. The limiter body 1 is located on the side away from the driving device, that is, the driven end of the rotating shaft. Further, taking the smart lock disclosed in Chinese Patent No. 202221726387.5 as an example, when the baffle of the smart lock is closed to the base, the side of the baffle with the roller component is used as the front end of the smart lock, and the other end is used as the rear end of the smart lock. The extension 2 is oriented toward the rear end of the smart lock, and there is a gap between the limiter body 1 and the base, so that the distance from the center of the shaft hole 11 to the base is less than the distance from the center of the shaft hole 11 to the end of the extension 2; when the output shaft of the drive device drives the rotating shaft to rotate, the rotating shaft drives the baffle to flip, and the limiter body 1 fixed on the rotating shaft rotates at the same time along the rotation direction of the baffle. There is an angle difference between the extension 2 and the baffle. If the end of the extension 2 contacts the base, the rotating shaft fixed to the limiter body 1 stops rotating, so that the baffle stops at a suitable flip angle.

[0022] The driven end flip limiter for a smart lock provided in Embodiment 1 of this utility model includes a limiter body 1, in which the rotating shaft of the smart lock is sleeved in the shaft hole 11, so that the limiter body 1 can be fixed to the rotating shaft, thereby allowing the limiter body 1 to rotate with the rotating shaft and maintain the same rotation angle as the rotating shaft. Further, in order to control the rotation angle of the rotating shaft, an extension 2 is provided at the left end of the limiter body 1, such that the distance from the center of the shaft hole 11 to the edge of the limiter body 1 is less than the distance from the center of the shaft hole 11 to the end of the extension 2. This ensures that when there is a gap between the limiter body 1 and the base after the limiter body 1 is installed on the rotating shaft, the rotation of the rotating shaft does not affect the rotation of the limiter body 1, while the extension 2 can contact the base, thereby preventing the rotating shaft from continuing to rotate. Even further, in order to control the baffle of the smart lock to rotate to a suitable angle, the extension 2... There is an angle difference between the extension 2 and the baffle. Increasing or decreasing the angle difference between the extension 2 and the baffle can control the flip angle or the lifting height of the baffle. Furthermore, when a vehicle drives over the smart lock with the baffle raised, the vehicle chassis is prone to scraping against the top of the baffle. At this time, the baffle is prone to continue to flip under force. When the baffle stops, the drive device is in a stationary state. The baffle continues to flip, causing the rotating shaft to rotate. The rotating shaft causes the output shaft of the drive device to rotate. If the instantaneous rotation force of the rotating shaft is too large, it is easy to cause the drive device to be damaged by force. Fixing the driven end flip limiter of the smart lock provided in Embodiment 1 of this utility model on the rotating shaft can transfer the force on the baffle to the base of the smart lock, thereby avoiding the force on the baffle being directly transferred to the output shaft of the drive device, preventing the drive device from being damaged by force, reducing the loss of the smart lock due to scraping by the vehicle base, and extending the service life of the smart lock.

[0023] In the prior art, using only a drive device to control the rotation of the baffle can easily lead to excessive rotation of the baffle, making it difficult to control the flip angle of the baffle and preventing the baffle from stopping at a suitable position, thereby affecting the use of the floor lock function. The driven end flip limiter for the smart floor lock provided in Embodiment 1 of this utility model has an extension 2 at the left end of the limiter body 1. The extension 2 contacts the base of the smart floor lock, thereby controlling the baffle to stop at a suitable flip angle and improving the stability of the baffle flipping function in the smart floor lock.

[0024] like Figures 1-3 As shown, the driven end flip limiter for the smart lock provided in Embodiment 1 of this utility model is preferably designed so that the extension 2 can contact the base of the smart lock. Specifically, the edge of the limiter body 1 is arc-shaped. When the output shaft of the drive device rotates, the shaft drives the limiter body 1 to rotate. Since there is a gap between the limiter body 1 and the base when the limiter body 1 is installed, setting the edge of the limiter body 1 to be arc-shaped can maintain the gap between the limiter body 1 and the base during rotation.

[0025] Furthermore, the side of the extension 2 adjacent to the limiter body 1 is straight, and the side of the extension 2 is tangent to the side of the limiter body 1. The rotating shaft of the smart lock drives the limiter body 1 to rotate. When the side of the extension 2 adjacent to the limiter body 1 is parallel to the base plane of the smart lock, if the limiter body 1 continues to rotate, the side of the extension 2 adjacent to the limiter body 1 will form an angle with the base plane of the smart lock. Since the distance from the center of the shaft hole 11 to the edge of the limiter body 1 is less than the distance from the center of the shaft hole 11 to the end of the extension 2, when the extension 2 contacts the base of the smart lock, the planar sidewall of the extension 2 will press against the base plane of the smart lock, thereby stopping the rotating baffle.

[0026] like Figure 3 As shown in Embodiment 1 of this utility model, the driven end flip limiter for a smart lock is preferably designed so that the rotating shaft of the smart lock can drive the limiter body 1 to rotate during rotation. Specifically, the vertical cross-section of the shaft hole 11 in the front-to-back direction is square, and the cross-section of the driven end of the rotating shaft is also set to square, so that the driven end of the rotating shaft can be fitted into the shaft hole 11. Since the shaft hole 11 is square, it can prevent the rotating shaft from sliding in the shaft hole 11 during rotation limiting, compared with the use of a circular shaft hole 11, thereby preventing the limiter body 1 from failing to rotate with the rotating shaft by the same angle.

[0027] like Figure 3As shown, the driven end flip limiter for the smart floor lock provided in Embodiment 1 of this utility model preferably has arc-shaped grooves 111 on both sides of the inner wall of the shaft hole 11. The openings of the two arc-shaped grooves 111 are arranged facing each other, and the cross section of the driven end of the rotating shaft is set as a rounded rectangle, so that the driven end of the rotating shaft can be sleeved in the shaft hole 11. By setting the arc-shaped grooves 111, it can play a positioning role when the rotating shaft is installed in the shaft hole 11, making it easy to sleeve the rotating shaft in the shaft hole 11.

[0028] like Figure 2 As shown, the driven end flip limiter for the smart floor lock provided in Embodiment 1 of this utility model is preferably provided with a cover plate 3 in order to fix the limiter body 1 to the rotating shaft of the smart floor lock; the two side plates of the limiter body 1 are respectively attached to the rotating shaft fixing member 4 and the cover plate 3, and the cover plate 3 is fixed to the rotating shaft by bolts through the screw holes on the rotating shaft and the cover plate 3, thereby preventing the limiter body 1 from falling off the rotating shaft when rotating.

[0029] In summary, the driven end flip limiter for intelligent floor locks provided by this utility model can solve the problem that the existing technology, which only uses a drive device to control the rotation of the baffle, easily leads to excessive rotation of the baffle, making it difficult to control the flip angle of the baffle and preventing the baffle from stopping at a suitable position, thus affecting the use of the floor lock function. It can limit the baffle and make the baffle stop at a suitable flip angle.
