Description

Technical Field

[0001] This utility model relates to the technical field of parking space management devices, and in particular to a parking space lock structure. Background Technology

[0002] Most parking space locks on the market currently use a motor-driven shaft to raise and lower a swing arm. Their locking function relies primarily on the interaction between transmission components (such as gears and linkages) and the shaft. However, this type of locking structure has significant drawbacks in its impact resistance: when the swing arm, in its raised and locked state, is subjected to external force (such as a vehicle accidentally bumping into the parking space or a person accidentally kicking it), the impact force is directly transmitted along the swing arm to the shaft and the connected transmission components. Because existing structures lack independent external force bearing and buffering mechanisms, the impact force cannot be effectively dispersed, easily causing the swing arm to bend and deform, and even leading to shaft twisting.

[0003] In view of the above-mentioned technical problems, this utility model proposes a new technical solution. By optimizing the limiting structure of the swing arm, an independent locking structure is formed by the direct contact between the swing arm and the base plate, which restricts the swing arm from continuing to rotate. It can also directly disperse the impact of external force to the base plate when subjected to external force, thereby effectively improving the anti-vandalism and anti-collision performance of the parking lock, avoiding damage to the transmission components, and extending the service life of the parking lock. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a parking lock structure, which aims to solve the technical problem that parking locks in the prior art rely on the cooperation of transmission components and rotating shafts to achieve locking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A parking lock structure includes a base plate and two rotatable swing arms. Each swing arm corresponds to a rotation axis and rotates around it. Each swing arm includes a main body section and an abutment section. The abutment section of each swing arm is provided with a first abutment plane, and the base plate is provided with a second abutment plane. During the rotation of the swing arm, the first abutment plane can abut against the second abutment plane to limit the swing arm from continuing to rotate.

[0006] Furthermore, in the parking lock structure, the two swing arms have the same specifications.

[0007] Furthermore, in the parking lock structure, the rotation axes of the two swing arms coincide.

[0008] Furthermore, in the parking lock structure, each swing arm has a clearance surface at its contact section, and the clearance surface does not interfere with the second contact plane during the rotation of the swing arm.

[0009] Furthermore, in the parking space lock structure, the clearance surface is a plane.

[0010] Furthermore, in the parking lock structure, the clearance surface is an arc surface, and each arc surface is set with the rotation axis of the corresponding swing arm as the central axis.

[0011] Furthermore, in the parking space lock structure, the second abutting plane is disposed on the upper surface of the base plate.

[0012] Furthermore, in the parking lock structure, a stop block is provided on the base plate, the stop block is located behind the swing arm, and the second abutment plane is provided on the front side wall of the stop block.

[0013] Beneficial effects: This utility model provides a parking space lock structure that, compared with the prior art, has at least the following advantages: (1) The first contact plane of the swing arm contact section abuts against the second contact plane of the base plate to form a lock. When an external force impacts, the load can be directly transmitted to the base plate through the contact plane and dispersed to the ground, avoiding the problem of the impact force acting directly on the shaft, gear and other transmission components. This effectively prevents the shaft from deforming or the transmission gear from breaking, greatly reduces the probability of equipment failure, extends the overall service life of the parking space lock, and reduces the user's maintenance and replacement costs.

[0014] (2) No additional buffer or reinforcement components are needed. The core function can be achieved simply by optimizing the structure of the swing arm and the base plate, which simplifies the overall structure, reduces the number of parts, and lowers production and assembly costs.

[0028] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0029] Please see Figures 1 to 12This utility model provides a parking space lock structure. The accompanying drawings are for illustrative purposes only and are not proportional to actual products. The drawings only depict structures relevant to the innovation of this application; some conventional structures are not specifically shown. Terms such as "first" and "second" used herein are merely different names for similar structures to facilitate explanation and are not intended to limit this application. For ease of explanation, some directional terms are unavoidable, but these directional terms are not intended to limit this application. When a vehicle enters a parking space, the direction the parking space lock faces towards the vehicle is "front," and the opposite direction is "rear."

[0030] This article will focus on the innovative aspect of the swing arm abutting against the base plate. The structure and principle of conventional parking locks (such as motors and gears) will not be elaborated in detail.

[0031] Please refer to the following first. Figures 1 to 8 The parking lock structure includes a base plate 1 and two rotatable swing arms 2. Each swing arm corresponds to a rotation axis and rotates around it. Each swing arm 2 includes a main body section 21 and an abutment section 22. The abutment section of each swing arm is provided with a first abutment surface 51, and the base plate is provided with a second abutment surface 52. During the rotation of the swing arm, the first abutment surface can abut against the second abutment surface to limit the swing arm from continuing to rotate. Figure 3 As shown, the part above the pivot hole 20 is the main body section 21 of the swing arm, and the part below the pivot hole 20 is the abutment section 22.

[0032] The rotatable connection between the swing arm and the base plate can be implemented in various ways. For ease of understanding, a preferred solution is provided here: a support 3 is fixedly connected (preferably welded) to each swing arm on the base plate 1. A rotating shaft 4 is rotatably mounted on the two supports. Each swing arm 2 is provided with a corresponding rotating shaft hole 20, and the rotating shaft 4 passes through the rotating shaft holes 20 of the two swing arms. There is no relative rotation between the swing arm and the rotating shaft (this can be achieved through key connection, welding, interference fit, etc., which are not limited here), but there is relative rotation between the rotating shaft and the support, thus allowing the swing arm to rotate relative to the base plate. Since the two swing arms are connected to the same rotating shaft, it also facilitates the parking lock to drive the two stops to rotate synchronously through the same motor, simplifying the transmission structure. It should be noted that in practical applications, the rotating shaft can be prevented from moving along its axial direction by setting a retaining ring, etc. Since the means of preventing the rotating shaft from moving axially are existing technologies and not the innovation of this utility model, the corresponding structure is not specifically shown in the attached drawings.

[0033] Preferably, the two swing arms 2 are of the same specification, and the axes of the two swing arms coincide. As mentioned above, preferably, the two swing arms 2 are connected to the same rotating shaft 4. In this case, the rotation axis of the swing arm is the axis 401 of the rotating shaft, the two swing arms are subjected to balanced forces, and both can stably bear external forces through the abutment structure when locked.

[0034] Furthermore, each swing arm 2 has a clearance surface 50 on its abutment section 22, which is connected to the second abutment plane. During the rotation of the swing arm, the clearance surface does not interfere with the second abutment plane. The significance of this design is that it eliminates the need to add extra clearance space to the base plate or adjust the layout of other components. By simply optimizing the surface shape of the abutment section, the functional requirements of rotation and locking can be met, thus reducing structural complexity.

[0035] Furthermore, such as Figure 3 As shown, the clearance surface 50 is a plane. Since a plane is easier to process and shape using conventional processes such as stamping and cutting compared to curved surfaces or other irregular surfaces, it reduces manufacturing costs.

[0036] Furthermore, such as Figure 4 As shown, the clearance surface 50 is an arc surface, and each arc surface is set with the rotation axis of the corresponding swing arm (i.e., the axis 401 of the rotating shaft) as the central axis. That is, the rotation axes of the arc surfaces 50 are concentric. During the rotation of the swing arm, the gap between the clearance surface and the second abutment plane remains consistent to avoid interference caused by excessively small local gaps during rotation.

[0037] In practical applications, there are multiple options for the specific positions of the first and second abutment planes. Two preferred options are provided below.

[0038] Please see Figure 5 and Figure 6 The second abutment surface 52 is disposed on the upper surface of the base plate 1. Correspondingly, the first abutment surface 51 is disposed at the bottom of the abutment section 22 of the swing arm (the "bottom" referred to here is based on...). Figure 4 and Figure 6 From the perspective of [the viewpoint], when the swing arm rotates to the locked position (at which point the swing arm is in a vertical position, such as [the viewpoint]), Figure 6 As shown in the attached figure, the first and second abutting planes abut against each other, preventing the swing arm from rotating further. In this configuration, the rotation axis of each swing arm is further eccentrically positioned along the width of the abutting section. As shown in the attached figure, the pivot is located on the left side of the abutting section (i.e., the rotation axis of the swing arm is eccentrically positioned along the width of the abutting section). This configuration provides more space for the first abutting plane, ensuring a sufficiently large contact area between the first and second abutting planes and guaranteeing the abutting effect.

[0039] Alternatively, a stop block 11 can be provided on the base plate 1, with the stop block located behind the swing arm. Figure 7 and Figure 8 From the perspective of the right side (rear), the second abutment plane 52 is set on the front side wall of the stop block 11. Figure 7 and Figure 8From the perspective, the left side is the "front". Accordingly, the first abutment plane is set on the rear side of the abutment section. When the swing arm rotates to the locked position (at this time, the swing arm is in a vertical state, such as...), Figure 8 As shown), the first and second contact planes abut against each other, and the swing arm can no longer rotate.

[0040] In practical applications, a motor is installed within the cavity formed by the base plate and the housing. The motor's main shaft is equipped with a driving gear, and a driven gear is installed on the rotating shaft. The driving and driven gears mesh, thereby enabling the motor to rotate and drive the rotating shaft. Since the above gear transmission is a conventional setup, it will only be briefly described here, and its specific structure will not be drawn in detail. Figures 9 to 12 The drawing illustrates a parking lock that incorporates the structure of the parking lock provided by this utility model. (Of course, the appendix...) Figures 9 to 12 The example shown is just one embodiment; the specific form of the parking lock is not limited to this.

[0041] To facilitate understanding, the working principle is briefly described below.

[0042] When the parking lock is in the retracted state (at which time it is in the unlocked state, such as...) Figure 9 and Figure 11 As shown), at this point, the two swing arms are horizontally positioned against the base plate. When locking the parking space, the motor drives the rotating shaft to rotate, causing the swing arms to rotate upwards around the axis of rotation. During this process, the clearance surface of the swing arm's contact section and the second contact surface of the base plate always maintain a gap to avoid interference. When the swing arms rotate to the locked position (as shown), Figure 10 and Figure 12 As shown), the first abutting plane of the abutting section is completely fitted and abutted against the second abutting plane of the base plate, restricting the swing arm from continuing to rotate, forming a locked state, and the motor no longer rotates.

[0043] If the swing arm is impacted by an external force while locked, the impact force is directly transmitted to the base plate (and then dispersed to the ground) through the surface contact of the first and second abutment surfaces. Since the swing arm cannot continue to rotate, it protects components such as the shaft, drive gear, driven gear, and motor shaft. When unlocked, the drive mechanism reverses the rotation of the shaft, causing the first and second abutment surfaces to separate, returning the arm to its retracted state.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of the present utility model, and all such modifications or substitutions should fall within the protection scope of the present utility model.
