Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional garages, and particularly relates to a front-wheel in-place detection device and a vehicle vertical lifter. Background Art

[0002] With the development of the society, economy and transportation in cities, it is increasingly difficult to meet the growing demand for parking spaces in terms of the floor area occupied by parking spaces in cities. The emergence of three-dimensional garages has greatly alleviated the parking pressure. Since three-dimensional garages save floor area by stacking vehicles vertically, it is necessary to lift the vehicle by a lifter.

[0003] During the process of lifting the vehicle by the lifter, if the vehicle is not parked in the middle of the platform, there is a deviation or left-right tilt, which will bring difficulties to the lifting system to complete its work tasks, and may even cause accidents in severe cases. In related technologies, front-wheel in-place detection is usually set at a certain position of the platform, and whether the front wheel is in place is detected to judge whether the parking position of the vehicle is reliable. However, in the prior art, a cylindrical roller is usually used to install a spring bracket, and after the vehicle wheel presses on the roller, the spring compresses to trigger the switch to achieve the front-wheel in-place detection function. In this way, the wheel can easily cross over, resulting in low detection stability. Content of the Utility Model

[0004] The main purpose of the utility model is to propose a front-wheel in-place detection device and a vehicle vertical lifter, aiming to at least solve the problem in related technologies that the wheel can easily cross over, resulting in low detection stability.

[0039] With the development of the society, economy and transportation of the city, it is increasingly difficult for the urban parking spaces to meet the growing demand for parking spaces. The emergence of the multi-storey garage has greatly alleviated the parking pressure. Since the multi-storey garage saves floor area by stacking vehicles vertically, a hoist is needed to lift the car.

[0040] During the process of the hoist lifting the vehicle, if the vehicle is not parked in the middle of the platform and is biased or tilted left and right, it will cause difficulties for the lifting system to complete its work tasks. In severe cases, it may even lead to accidents. In related technologies, usually a front-wheel in-place detection is set at a certain position of the platform, and the parking position of the vehicle is judged by detecting whether the front wheels are in place. However, in the existing technologies, usually a cylindrical roller is used to install a spring bracket. After the vehicle wheel presses on the roller, the spring compresses to trigger the switch to achieve the front-wheel in-place detection function. In this way, the wheel can easily cross over, resulting in low detection stability.

[0041] The present utility model provides a front-wheel in-place detection device and a vehicle vertical hoist, aiming to at least solve the problem in related technologies that the wheel can easily cross over, resulting in low detection stability.

[0042] Please refer to Figure 1 and Figure 2 In an embodiment of the present utility model, the front-wheel in-place detection device 100 includes a base 1, a support plate 2 and a detection assembly 3. The support plate 2 is inclined and arranged on the base 1 with a gap therebetween, and the support plate 2 is movably arranged in a direction close to and away from the base 1. The detection assembly 3 includes a detection part and a trigger part. One of the detection part and the trigger part is arranged on the base 1, and the other is arranged on the support plate 2 to move along with the support plate 2, so as to have an in-place position and a separated position. In the in-place position, the detection part and the trigger part are in contact to form a detection circuit and send an in-place signal. In the separated position, the detection part and the trigger part are separated to form a detection open circuit.

[0043] In the technical solution of the present utility model, the support plate 2 is inclined and arranged on the base 1 with a gap therebetween, and the support plate 2 is movably arranged in a direction close to and away from the base 1. The detection assembly 3 includes a detection part and a trigger part. One of the detection part and the trigger part is arranged on the base 1, and the other is arranged on the support plate 2 to move along with the support plate 2, so as to have an in-place position and a separated position. Thus, when the front wheel of the vehicle travels to contact the support plate 2, it will give the support plate a driving force to move towards the base 1, so that the detection part and the trigger part are in contact to form a detection circuit, thereby sending an in-place signal, indicating that the front wheel of the vehicle has reached the position. And since the support plate 2 is inclined, it is difficult for the front wheel of the vehicle to cross over, maintaining the stability of the detection.

[0044] There are various forms of the detection part and the triggering part. In the embodiment of the present utility model, the detection part includes a microswitch 31 arranged on the base 1, and a part of the support plate 2 constitutes the triggering part. In this way, when the support plate 2 is squeezed by the wheel, it will move towards the base 1 until it contacts the microswitch 31, thereby activating the microswitch 31. Of course, the microswitch 31 can also be arranged on the support plate 2, and a part of the base 1 constitutes the triggering part. In another implementation manner, the detection part and the triggering part can be two contact pieces separately arranged on the base 1 and the support plate 2, and a closed circuit is formed through the contact of the contact pieces.

[0045] The inclination angle of the support plate 2 relative to the horizontal plane should not be too large or too small. If the inclination angle is too large, although it is more difficult for the front wheel of the vehicle to cross the support plate 2, the height of the overall structure will be higher, and there may be a problem of scraping the vehicle chassis. If the inclination angle is too small, although it can better rely on the weight of the vehicle body to make the detection part and the triggering part contact, it will be easier to cross the support plate 2. Therefore, the inclination angle of the support plate 2 relative to the horizontal plane is between 30 degrees and 60 degrees; preferably, the inclination angle of the support plate 2 is 45 degrees.

[0046] In order to enable the base 1 to better provide a supporting effect for the support plate 2 at the in-place position, in some implementation manners, please refer to Figures 1 to 4 , the upper surface of the base 1 is an inclined surface, and the support plate 2 is arranged opposite to the inclined surface of the base 1. In this way, the inclined surface of the base 1 is arranged opposite to the support plate 2. At the in-place position, there can be a larger contact area between the inclined support plate 2 and the inclined surface, thereby being able to provide a stable supporting force for the wheel, and the support plate 2 is not easily broken.

[0047] In order to further increase the contact area between the inclined surface of the base 1 and the support plate 2, the angle of the inclined surface is equal to the inclination angle of the support plate 2, that is, the inclined surface and the support plate 2 are arranged in parallel. In this way, the base 1 can better provide stable support for the support plate 2.

[0048] There are various ways to form the inclined surface. For example, an inclined surface can be cut on a long bar. In the embodiment of the present utility model, the base 1 includes a bent bottom plate 11 and inclined plates 12 connecting both ends of the bent bottom plate 11. The side surface of the inclined plate 12 facing the support plate 2 constitutes the inclined surface; in this way, the overall base 1 is composed of the bent bottom plate 11 and the inclined plates 12 to form a hollow triangular prism structure. While saving materials, the stability of the triangle makes the overall structure not easily damaged when the wheel presses on the support plate 2 and the base 1.

[0049] In order to improve the strength of the overall base 1, a triangular support block can be provided between the bent bottom plate 11 and the inclined plate 12.

[0050] In order to enable the support plate 2 to reset after the wheel is separated from the support plate 2, in some embodiments, please refer to Figure 1 and Figure 3 , the front wheel in-place detection device 100 further includes a reset member 4, and the reset member 4 is used to provide a driving force for the support plate 2 to move away from the base 1. In this way, the reset force of the reset member 4 is used to drive the support plate 2 away from the base 1, so as to prevent the detection part and the triggering part from still being in contact and providing incorrect information after the wheel is separated from the support plate 2.

[0051] The form of the reset member 4 is various. In some embodiments, the reset member 4 includes a spring 41 disposed between the base 1 and the support plate 2. In this way, after the support plate 2 is separated from the wheel, the support plate 2 can automatically reset under the elastic action of the spring 41 without manual operation. The reset member 4 is not limited to the form of the spring 41. The reset member 4 can also be other elastic components or assemblies such as an elastic block. Of course, the reset member 4 can also be a magnetic member with the same-sex repulsion.

[0052] Furthermore, in order to save the installation space of the spring 41, in some embodiments, a groove 13 is provided on the base 1, and at least a part of the spring 41 is located in the groove 13; with such a setting, the installation space of the spring 41 can be saved through the groove 13, so that the support plate 2 and the base 1 can be as close as possible, and the relative stroke when the detection part and the triggering part need to be in contact is shorter, and the detection is more reliable.

[0053] In order to improve the stability of the movement of the support plate 2 relative to the base 1, in some embodiments, please refer to Figure 1 and Figure 4 , the front wheel in-place detection device 100 further includes a guiding member 5. The guiding member 5 includes a guiding part and a guiding cooperation part respectively provided on the base 1 and the support plate 2, and the guiding part and the guiding cooperation part are in sliding cooperation to guide the movement of the support plate 2. In this way, the stability of the movement of the support plate 2 is improved through the sliding cooperation between the guiding part and the guiding cooperation part, and further the stability of the overall structure for detecting the front wheel of the vehicle can be increased.

[0054] There are various forms of the guiding part and the guiding cooperation part. For example, the form of a slider and a sliding groove can be adopted for guiding. In the embodiment of the present utility model, one of the guiding part and the guiding cooperation part is provided with a guiding hole 51, and the other is provided as a guiding shaft 52; thus, the stability of the relative movement of the support plate 2 with respect to the base 1 is maintained by means of the guiding shaft 52 and the guiding hole 51. Among them, the guiding hole 51 can be provided on the base 1 or on the support plate 2.

[0055] In order to reduce the possibility of the separation of the guiding shaft 52 and the guiding hole 51, a retaining ring 53 is provided on the guiding shaft 52, and the outer diameter of the retaining ring 53 is larger than the aperture of the guiding hole 51, so that the retaining ring 53 cannot pass through the guiding hole 51, ensuring that the guiding hole 51 and the guiding shaft 52 will not separate.

[0056] It can be understood that under the elastic action of the spring 41, the retaining ring 53 will impact the end of the guiding hole 51, which is likely to cause damage to the retaining ring 53 in the long run. In order to reduce the possibility of damage to the retaining ring 53, the retaining ring 53 can be made of an elastic material. The present design does not limit the specific elastic material of the retaining ring 53, which can be rubber or silicone, etc.

[0057] The present utility model also proposes an automotive vertical lifter, which includes a lifting bracket 200 and a front-wheel in-place detection device 100. The specific structure of the front-wheel in-place detection device 100 refers to the above embodiment. Since this automotive vertical lifter adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the two front-wheel in-place detection devices 100 are respectively arranged on the opposite sides of the lifting bracket 200.

[0058] In the technical solution of the present utility model, the support plate 2 is inclined and arranged on the base 1 with a gap therebetween. The support plate 2 is movably arranged in a direction close to and away from the base 1. The detection assembly 3 includes a detection part and a triggering part. One of the detection part and the triggering part is arranged on the base 1, and the other is arranged on the support plate 2 to move along with the support plate 2, so as to have a in-place position and a separated position; thus, when the front wheel of the vehicle travels to contact the support plate 2, a driving force for the support plate to move towards the base 1 will be given, so that the detection part and the triggering part come into contact to form a detection circuit, thereby sending an in-place signal indicating that the front wheel of the vehicle has reached the position. And since the support plate 2 is inclined, it is difficult for the front wheel of the vehicle to cross over, maintaining the stability of detection.

[0059] The above are only exemplary embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included within the patent protection scope of the present utility model.
