Description

Technical Field

[0001] This utility model relates to the field of vehicle inspection technology, and more specifically to a vehicle chassis height detection device. Background Technology

[0002] Today, parking equipment is frequently used for storing and retrieving vehicles. Parts of the parking equipment can extend under the vehicle chassis to move the vehicle to a parking space. However, there are requirements regarding the height of the vehicle chassis when using parking equipment to move vehicles. If the vehicle chassis height is lower than a preset height, the parking equipment cannot extend under the chassis, making it impossible to move the vehicle. Some vehicles with low chassis only discover that the parking equipment cannot move them when they arrive at the parking area, reducing parking efficiency and potentially causing the vehicle to get stuck or damaged during transport.

[0003] Therefore, this utility model provides a vehicle chassis height detection device to at least partially solve the above-mentioned problems. Utility Model Content

[0004] The utility model description section introduces a series of simplified concepts, which will be further described in detail in the detailed embodiments section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0053] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0054] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0055] In this document, ordinal numbers such as “first” and “second” used in this application are merely identifiers and do not have any other meaning, such as a specific order.

[0056] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0057] This invention provides a vehicle chassis height detection device 100. The vehicle chassis height detection device 100 can be installed at the entrance of a parking space or parking lot. When a vehicle is about to enter a parking space or parking lot, for example, when the vehicle is moving between the parking lot and the parking space, it needs to pass through the vehicle chassis height detection device 100. At this time, the vehicle chassis height detection device 100 can detect whether the height of the vehicle chassis is lower than a preset height. This preset height can be a height suitable for parking equipment such as a vehicle handling robot to enter under the vehicle to move the vehicle, for example, slightly higher than the height of the parking equipment such as a vehicle handling robot. When the swing frame 130 is in a vertical position, the height of the detection end 140 connected to the swing frame 130 is set to the preset height. The preset height can be set as needed. If the height of the vehicle chassis is higher than the preset height, the parking equipment such as a vehicle handling robot can enter under the vehicle chassis. If the height of the vehicle chassis is lower than the preset height, the parking equipment such as a vehicle handling robot cannot enter under the vehicle chassis.

[0058] The vehicle chassis height detection device 100 includes a base frame 110, at least one swing frame 130, at least one detection end 140, a trigger 151, and a detection switch 152. The swing frame 130 is pivotally connected to the base frame 110 between a vertical position and a tilted position. In the vertical position, the swing frame 130 protrudes upwards from the base frame 110 in the height direction. The detection end 140 is rotatably connected to the swing frame 130 and protrudes upwards from the swing frame 130 in the height direction. The trigger 151 is fixedly connected to the lower end of the swing frame 130. The detection switch 152 is located below the trigger 151. The swing frame 130 can drive the trigger 151 to trigger the detection switch 152 to generate a sensing signal.

[0059] According to the vehicle chassis height detection device 100 of this utility model, if the vehicle chassis is lower than the detection end 140 of the vehicle chassis height detection device 100, when the vehicle passes over the vehicle chassis height detection device 100, the swing frame 130 will pivot to a flipped position, which can prevent the detection end 140 from directly impacting the vehicle chassis. Furthermore, the pivoting of the swing frame 130 can drive the trigger 151 to trigger the detection switch 152. Therefore, vehicles with chassis lower than the detection end 140 of the vehicle chassis height detection device 100 can be detected in a timely manner, preventing parking equipment from jamming or damaging vehicles with low chassis when handling them, and also preventing situations where the parking equipment cannot handle the vehicle when it arrives at the parking area, thus reducing parking efficiency. At the same time, the detection end 140 is rotatably connected to the swing frame 130, further preventing the detection end 140 from scratching or damaging the vehicle chassis.

[0060] It should be noted that the "vertical position" in this utility model refers to a roughly vertical position, while the "flipping position" can be a position different from the "vertical position" in the pivoting path of the swing frame 130. The vehicle's travel direction can be roughly perpendicular to the axial direction of the pivot shaft 132 described below.

[0061] Please refer to Figures 1 to 4 The vehicle chassis height detection device 100 may include a base frame 110, at least one swing frame 130, at least one detection end 140, a trigger 151, a connecting seat 160, at least one reset element 180, and a detection switch 152.

[0062] refer to Figures 1 to 4 The base frame 110 may include two oppositely arranged end plates 112, two oppositely arranged first side plates 113, a bottom plate 114, and an inverted U-shaped cover plate 115. The first side plates 113 may be connected between the two end plates 112, and the end plates 112 may be connected between the two first side plates 113. The bottoms of the two end plates 112 and the two first side plates 113 may be connected to the bottom plate 114. The inverted U-shaped cover plate 115 may include a top plate 115a and two oppositely arranged second side plates 115b, with the two second side plates 115b respectively connected to the two first side plates 113. The top plate 115a is disposed between the two second side plates 115b and is located above the two end plates 112 and the two first side plates 113. The top plate 115a has an opening 115c, and the size of the swing frame 130 is adapted to the size of the opening 115c to avoid interfering with the pivoting of the swing frame 130. The two second side plates 115b of the inverted U-shaped cover 115 can be detachably connected to the two first side plates 113 by fasteners, thereby making it easy to install and remove the inverted U-shaped cover 115 for easy inspection or maintenance.

[0063] The swing frame 130, detection end 140, trigger 151, connecting seat 160, reset element 180, and detection switch 152 are all horizontally disposed within the base frame 110. Thus, the structure of the base frame 110 protects the swing frame 130, at least one detection end 140, trigger 151, connecting seat 160, at least one reset element 180, and detection switch 152, and prevents accidental triggering of the detection switch 152. The inverted U-shaped cover 115 further enhances protection and further prevents accidental triggering of the detection switch 152.

[0064] Understandably, the axial dimension of the vehicle chassis height detection device 100 is smaller than the axial dimension between the two wheels of the vehicle, so that the vehicle chassis height detection device 100 can be used to detect the vehicle chassis height.

[0065] In the illustrated embodiment, the swing frame 130 is pivotally connected to the end plate 112 via two separately arranged pivot shafts 132 between the vertical and tilted positions. A detection switch 152 and a trigger 151 are arranged between the two spaced-apart pivot shafts 132 along the axial direction of the pivot shafts 132. This prevents the pivot shafts 132 from interfering with the operation of the detection switch 152 and the trigger 151, and prevents interference with the engagement between the detection switch 152 and the trigger 151.

[0066] The flipping positions may include a first flipping position and a second flipping position. The swing frame can be pivotally connected to the underframe in two opposite directions, between the vertical position and the first flipping position, and between the vertical position and the second flipping position, respectively. These two opposite directions are parallel to the vehicle's direction of travel. In the illustrated embodiment, the swing frame 130 is pivotally connected to the end plate 112 between the vertical position and the flipping position. The two flipping positions (first flipping position and second flipping position) are arranged on both sides of the axial direction of the pivot axis 132 (direction of travel) perpendicular to the axial direction of the pivot axis 132. The swing frame 130 can flip bidirectionally in the direction perpendicular to the axial direction of the pivot axis 132 (parallel to the vehicle's direction of travel), which can also be interpreted as being able to flip forward or backward from the vertical position. Figure 4 For reference, the vehicle can be positioned to the left and / or right of the vehicle chassis height detection device 100, and driven towards the device in an axial direction perpendicular to the pivot axis 132, to detect whether the vehicle chassis height is higher than a preset height. This improves the convenience of detection and also increases the utilization rate of the vehicle chassis height detection device 100.

[0067] refer to Figures 1 to 4 The swing bracket 130 can be connected to the base frame 110 via a pivot shaft 132 between the vertical position and the tilted position. In the vertical position, the swing bracket 130 protrudes upwards from the base frame 110 in the height direction. A detection end 140 is rotatably connected to the swing bracket 130, and protrudes upwards from the swing bracket 130 in the height direction. Understandably, when the swing bracket 130 is in the vertical position, the top of the detection end 140 is the highest position of the vehicle chassis height detection device 100.

[0068] Therefore, if the vehicle chassis is lower than the detection end 140 of the vehicle chassis height detection device 100, when the vehicle passes over the vehicle chassis height detection device 100, the swing frame 130 is in a vertical position, and the detection end 140 is at the highest position of the vehicle chassis height detection device 100. Due to the vehicle collision, the detection end 140 tilts downwards along the driving direction, and the detection end 140 drives the swing frame 130 to pivot downwards along the driving direction to the flipped position. The detection end 140 is rotatably connected to the swing frame 130, which avoids the detection end 140 from scraping or being damaged by the vehicle chassis.

[0069] Trigger 151 is fixedly connected to the lower end of swing frame 130. Detection switch 152 is located below trigger 151. Swing frame 130 can drive trigger 151 to trigger detection switch 152 to generate a sensing signal. Vehicle chassis height detection device 100 may also include a controller (not shown) and an actuator (not shown). The controller may be electrically connected to detection switch 152 and actuator such as an audible and visual alarm. After receiving the sensing signal, the controller can send, for example, control signals (or control commands) to actuator such as an audible and visual alarm, thereby enabling the actuator to perform actions such as emitting sound and light signals to remind the driver and staff that the vehicle chassis is lower than the detection end 140 of vehicle chassis height detection device 100, that is, the height of the vehicle chassis is lower than a preset height, making it unsuitable for parking equipment such as vehicle handling robots to enter under the vehicle for vehicle handling.

[0070] When the vehicle leaves the vehicle chassis height detection device 100, the swing frame 130 returns to the vertical position under the action of the reset member 180, the detection switch 152 stops sending the sensing signal to the controller, and the controller stops controlling the actuator to perform actions such as emitting sound and light signals.

[0071] Understandably, when the vehicle chassis height is higher than the preset height, the vehicle travels in the direction of travel toward the vehicle chassis height detection device 100. When passing the vehicle chassis height detection device 100, it will not contact the detection end 140, and therefore will not trigger the detection switch 152. At this time, parking equipment such as a handling robot can enter under the vehicle chassis, clamp the vehicle's four tires, and lift the vehicle, thereby moving the vehicle between the parking lot and the parking space.

[0072] In the illustrated embodiment, the detection switch 152 can be mounted on the base plate 114 of the chassis 110, thereby allowing the vehicle chassis height detection device 100 to be moved integrally, facilitating its relocation to any desired location. Furthermore, it also prevents the external environment from affecting the detection switch 152.

[0073] In some embodiments not shown, the detection switch 152 may also be located on the ground below the trigger 151.

[0074] In the illustrated embodiment, when the swing frame 130 pivots to the flip position, it can drive the trigger 151 away from the sensing range of the detection switch 152. The detection switch 152 is configured to trigger the detection switch 152 to generate a sensing signal when the trigger 151 leaves the sensing range of the detection switch 152.

[0075] In the illustrated embodiment, the detection switch 152 may include a transmitter and a receiver, which may be located generally in a straight line parallel to the axial direction. The transmitter is used to emit a light beam to the receiver, and the trigger 151 is configured to partially overlap with the detection switch 152 in a vertical plane along the axial direction of the pivot axis 132, such that the receiver cannot receive the light beam from the transmitter when the trigger 151 is within the sensing range, and the receiver can receive the light beam from the transmitter when the trigger 151 is outside the sensing range. Understandably, the sensing range is set such that the trigger 151 can completely block the transmitter, preventing the light beam from reaching the receiver; that is, the range of positions where the trigger 151 is located when the light beam reaching the receiver is 0.

[0076] refer to Figure 1 , Figure 3 and Figure 4 The detection switch 152 may include a base 152a and two opposing support plates 152b. The base 152a is fixedly connected to the base frame 110, and each of the two support plates 152b is respectively provided with a transmitter and a receiver. A trigger 151 is located axially between the transmitter and the receiver. When the trigger 151 is within the sensing range, the receiver cannot receive the light beam from the transmitter; when the trigger 151 leaves the sensing range, the receiver can receive at least a portion of the light beam from the transmitter. In other words, the state when the light beam emitted by the transmitter is blocked is considered normal, and the state when the receiver receives the light beam emitted by the transmitter is triggered. At this time, the trigger 151 leaves the space between the transmitter and the receiver, and the light beam emitted by the transmitter is received by the receiver. At this time, the detection switch 152 is in the triggered state.

[0077] Of course, if needed and / or desired, the receiver can be set to receive the beam from the transmitter in a normal state, and the beam emitted by the transmitter can be blocked in a triggered state. At this time, the trigger 151 enters the space between the transmitter and the receiver, that is, the trigger 151 enters the sensing range. At this time, the beam is blocked by the trigger 151, and the detection switch 152 is in the triggered state.

[0078] In some embodiments not shown, when the swing frame 130 pivots to the flip position, it can drive the trigger 151 into the sensing range of the detection switch 152, which is configured to trigger the detection switch 152 to generate a sensing signal when the trigger 151 is within the sensing range of the detection switch 152.

[0079] In some other embodiments not shown, the detection switch 152 may be a contact switch such as a microswitch. The detection switch 152 may include a body and a trigger pin connected to the body. When the swing arm 130 pivots to the flip position, it can actuate the trigger element 151 to press the trigger pin of the microswitch, triggering the microswitch to generate a sensing signal, which has the advantage of rapid action. Understandably, the sensing range at this time is the position where the trigger element 151 directly presses the trigger pin of the microswitch.

[0080] In the illustrated embodiment, the swing frame 130 may include two swing plates 131 spaced apart along the axial direction, and a mounting plate 133 is connected between the two swing plates 131 along the axial direction. A reinforcing plate 134 may be provided between the mounting plate 133 and the two swing plates 131 to strengthen the structure of the swing frame 130. The two swing plates 131 may be arranged substantially parallel to each other.

[0081] The vehicle chassis height detection device 100 may include at least two swing arms 130 and at least two detection ends 140, with each detection end 140 correspondingly connected to one swing arm 130. When the at least two swing arms 130 are in a vertical position, the at least two detection ends 140 have different heights. Therefore, the vehicle chassis height detection device 100 can have at least two preset heights. For example, one vehicle chassis height detection device 100 can be used to detect at least two different vehicle chassis heights, improving detection efficiency, increasing the utilization rate of the vehicle chassis height detection device 100, and reducing costs.

[0082] In some embodiments, at least two swing frames 130 may be arranged parallel to each other along the direction of travel. In other embodiments, at least two swing frames 130 may be arranged in a straight line parallel to the axial direction, in which case the two outermost swing plates 131 are respectively connected to the connecting seats 160 on both sides of the base frame 110 (see below).

[0083] In some embodiments of the vehicle chassis height detection device 100, the two preset heights are a first preset height (e.g., slightly higher than the height of a first parking device) and a second preset height (e.g., slightly higher than the height of a second parking device). The vehicle chassis height detection device 100 may include two swing arms 130 and two detection ends 140. The two swing arms 130 include a first swing arm 130 and a second swing arm 130. The two detection ends 140 include a first detection end 140 and a second detection end 140. The first detection end 140 is correspondingly connected to the first swing arm 130. The second detection end 140 is correspondingly connected to the second swing arm 130. When the first swing arm 130 and the second swing arm 130 are in a vertical position, the heights of the first detection end 140 and the second detection end 140 are different. When the vehicle chassis height is higher than the first preset height, both the first parking device and the second parking device can drive under the vehicle chassis. When the vehicle chassis height is lower than the second preset height, neither the first parking device nor the second parking device can drive under the vehicle chassis. When the vehicle chassis height is higher than the second preset height but lower than the first preset height, the second parking device can drive under the vehicle chassis, but the first parking device cannot drive under the vehicle chassis.

[0084] Understandably, when the driver or staff can roughly assess that the vehicle chassis height is lower than the first preset height, the reset pieces 180 on both sides of the first swing frame 130 can be removed, the first swing frame 130 can be placed in the flipped position, and then the second swing frame 130 and the second detection end 140 rotatably connected to the second swing frame 130 can be used to detect whether the vehicle chassis height is higher than the second preset height, thereby preventing the first detection end 140 from interfering with the detection of whether the vehicle chassis height is higher than the second preset height.

[0085] refer to Figure 1 and Figure 3 The connecting seat 160 can be detachably connected axially between the base frame 110 and the swing plate 131, and the swing plate 131 can be pivotally connected to the connecting seat 160 via the pivot shaft 132. This facilitates convenient and secure installation of the swing frame 130. The connecting seat 160 can be connected to the end plate 112 via fasteners, thereby facilitating convenient disassembly of the connecting seat 160.

[0086] refer to Figure 4The vehicle chassis height detection device 100 also includes at least one reset member 180, which is connected between the first side plate 113 of the chassis 110 and the swing frame 130 along the vehicle's travel direction so that the swing frame 130 can return to or remain in a vertical position, with the vehicle's travel direction perpendicular to the axial direction. In the illustrated embodiment, two reset members 180, such as tension springs, are mounted on both sides of the swing frame 130 along the axial direction, allowing the swing frame 130 to remain relatively stably in a vertical position. If the vehicle hits the detection end 140 and the swing frame 130 in the travel direction and rolls them to a flipped position, after the vehicle leaves, the reset member 180 can cause the swing frame 130 to return to a vertical position, and the swing frame 130 drives the detection end 140 to reset, that is, the swing frame 130 drives the top of the detection end 140 back to its highest position.

[0087] refer to Figure 3 and Figure 4 The swing frame 130 may further include a mounting plate 133, which is axially connected between the two swing plates 131. At least one first mounting hole 133a is provided on each side of the mounting plate 133 along the travel direction. The base frame 110 also includes a mounting seat 111, whose position corresponds to the position of the first mounting hole 133a. The mounting seat 111 may have a second mounting hole 111a. Both ends of the reset member 180 along the travel direction can be respectively connected to the first mounting hole 133a and the second mounting hole 111a of the mounting seat 111. Thus, the reset member 180 can be easily installed.

[0088] The mounting plate 133 has at least two first mounting holes 133a on each side along the driving direction.
