[0033] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.
[0034] like Figures 1 to 10 As shown, this utility model provides an electric loading and unloading device for the rear compartment of a vehicle, comprising: a slide rail 3, which is horizontally arranged within the rear compartment 16; a pull-out bracket 1, which is slidably arranged on the slide rail 3; a horizontal drive mechanism 18, which is connected to the pull-out bracket 1 and is used to drive the pull-out bracket 1 to move along the slide rail 3; a lifting bracket 5, which is vertically arranged on the pull-out bracket 1; a lifting drive mechanism 8, which is connected to the lifting bracket 5 and is used to drive the lifting bracket 5 to rise and fall relative to the lifting bracket 5; a transition platform 6, which is detachably connected to the lifting bracket 5 and is arranged at the lower part of the lifting bracket 5; and a leveling foot 7, which is arranged on the transition platform 6 and extends downward to the lower part of the lifting bracket 5. When the lifting bracket 5 is lowered to its lowest position, the leveling foot 7 supports the ground to support the transition platform 6 and keeps the lower part of the lifting bracket 5 suspended.
[0035] The working process of the electric loading and unloading device for the rear compartment of a vehicle provided by this utility model is as follows:
[0036] (1) Unloading process (measuring equipment 17 is moved from the rear compartment 16 of vehicle 15 to the ground)
[0037] Activate the horizontal drive mechanism 18 to push the pull-out bracket 1 to slide outward along the slide rail 3, moving the lifting bracket 5 and measuring equipment 17 out of the rear compartment 16. After the pull-out bracket 1 is fully extended, the lifting bracket 5 and measuring equipment 17 are suspended outside the vehicle, and the transition platform 6 is in the waiting-to-land position. Activate the lifting drive mechanism 8 to slowly lower the lifting bracket 5, bringing the transition platform 6 close to the ground. The lifting bracket 5 continues to descend until it reaches its lowest position, with the lower part of the lifting bracket 5 suspended in the air. At this point, the weight of the measuring equipment 17 is completely supported by the leveling feet 7. Release the connection between the transition platform 6 and the lifting bracket 5, and the vehicle 15 drives away. The lifting bracket 5 follows the vehicle 15 and separates from the transition platform 6. The measuring equipment 17 is supported by the transition platform 6 and stably placed on the ground by the leveling feet 7.
[0038] (2) Loading process (measuring equipment 17 is moved from the ground to the rear compartment 16 of vehicle 15)
[0039] Vehicle 15 reverses to the vicinity of measuring equipment 17, aligning the lifting bracket 5 with the transition platform 6. The transition platform 6 (including measuring equipment 17) is secured to the lifting bracket 5. The lifting drive mechanism 8 is activated, raising the lifting bracket 5 so that the leveling feet 7 are off the ground, and the measuring equipment 17 is fully supported by the lifting bracket 5. The horizontal drive mechanism 18 is activated, pulling the pull-out bracket 1 inward along the slide rail 3, retracting the measuring equipment 17 into the rear compartment 16.
[0040] The transition platform 6 can be fixedly connected to the measuring equipment 17 by fastening bolts.
[0041] This invention enables rapid and stable loading and unloading of large photoelectric measuring equipment 17, especially heavy measuring equipment 17. The vehicle described in this invention can be a Land Cruiser.
[0042] In a preferred embodiment, in the electric loading and unloading device for the rear compartment of a vehicle, the lifting bracket 5 includes a vertical frame and a pair of horizontally arranged support rods 12. The pair of support rods 12 are parallel to each other, and their front ends are respectively connected to the lower end of the vertical frame. The pair of support rods 12 and the vertical frame form a square frame structure with a rear opening. The transition platform 6 is detachably connected to the pair of support rods 12, disposed between the pair of support rods 12, and located above the pair of support rods 12. When the lifting bracket 5 is lowered to its lowest position and the transition platform 6 is detached from the lifting bracket 5, and the lifting bracket 5 moves forward, the transition platform 6 disengages from the lifting bracket 5 through the opening.
[0043] The working process of the electric loading and unloading device for the rear compartment of a vehicle provided by this utility model is as follows:
[0044] (1) Unloading process (measuring equipment 17 is moved from the rear compartment 16 of vehicle 15 to the ground)
[0045] The transition platform 6 is fixed to a pair of support rods 12 at the lower part of the lifting bracket 5. The horizontal drive mechanism 18 is activated, pushing the pull-out bracket 1 to slide outward along the slide rail 3, moving the lifting bracket 5 and measuring equipment 17 out of the rear compartment 16. After the pull-out bracket 1 is fully extended, the lifting bracket 5 and measuring equipment 17 are suspended outside the vehicle, and the transition platform 6 is in the landing position. The lifting drive mechanism 8 is activated, slowly lowering the lifting bracket 5 so that the transition platform 6 is close to the ground. The lifting bracket 5 continues to descend until it reaches its lowest position, with the support rods 12 suspended in the air. At this point, the weight of the measuring equipment 17 is completely supported by the leveling feet 7. The connection between the transition platform 6 and the lifting bracket 5 is released, and the vehicle 15 drives away. The lifting bracket 5 moves forward with the vehicle 15, and the transition platform 6 detaches from the lifting bracket 5 through the rear opening of the square frame structure. The measuring equipment 17, supported by the transition platform 6, is stably placed on the ground by the leveling feet 7.
[0046] (2) Loading process (measuring equipment 17 is moved from the ground to the rear compartment 16 of vehicle 15)
[0047] Vehicle 15 reverses to the vicinity of measuring equipment 17, aligning the lifting bracket 5 with the transition platform 6. Vehicle 15 is slowly driven, allowing the transition platform 6 to gradually enter the interior of the rectangular structure through the rear opening, eventually resting completely above the pair of support rods 12, thus securing the transition platform 6 (including measuring equipment 17) to the rectangular structure. The lifting drive mechanism 8 is activated, raising the lifting bracket 5 so that the leveling feet 7 are off the ground, and the measuring equipment 17 is fully supported by the lifting bracket 5. The horizontal drive mechanism 18 is activated, pulling the pull-out bracket 1 inward along the slide rail 3, retracting the measuring equipment 17 into the rear compartment 16.
[0048] In this embodiment, the transition platform 6 extends two connecting pieces 14 to both sides. The connecting pieces 14 are mounted on corresponding support rods 12 and connected to the support rods 12 by fastening bolts. The vertical frame of the lifting bracket 5 is connected to a pair of support rods 12 by a pair of turnbuckles 2. The pull-out bracket includes a pair of vertical support rods and a crossbeam. The crossbeam is located at the top of the pair of vertical support rods. The vertical support rods are equipped with vertical guide rails, and the vertical frame of the lifting bracket is slidably mounted on the vertical guide rails.
[0049] Based on this embodiment, it is easy to combine and separate the lifting support 5 and the transition platform 6 without manual operation of the combination and separation process of the lifting support 5 and the transition platform 6, which can improve the efficiency of loading and unloading the measuring equipment 17.
[0050] In a preferred embodiment, in the electric loading and unloading device for the rear compartment of a vehicle, the rear ends of the pair of support rods 12 are respectively provided with guide angles 13, so that the opening is flared.
[0051] The guide angle 13 helps to increase the gap between the opening of the lifting bracket 5 and the transition platform 6, making it easier for the lifting bracket 5 to dock with the transition platform 6, which can improve the loading efficiency of the measuring equipment 17.
[0052] In a preferred embodiment, in the electric loading and unloading device for the rear compartment of a vehicle, the vertical frame includes a crossbar 9, the crossbar 9 is located at the lower end of the vertical frame, the crossbar 9 is provided with a guide pin 10, and the front of the transition platform 6 is provided with a guide hole; when the transition platform 6 is connected to the lifting bracket 5, the guide pin 10 passes through the guide hole.
[0053] After the measuring equipment 17 is retracted into the rear compartment 16, the equipment and the transition platform 6 can be secured a second time to improve the stability and reliability of the measuring equipment 17 during transportation. Specifically, in this embodiment, a guide hole is provided at the front of the transition platform 6, and the guide pin 10 of the lifting platform passes through the guide hole to fix the transition platform 6 and prevent the transition platform 6 from swaying left and right.
[0054] In a preferred embodiment, in the electric loading and unloading device for the rear compartment of a vehicle, when the transition platform 6 is connected to the lifting bracket 5, the rear part of the transition platform 6 is fixedly connected to the bottom wall of the rear compartment 16 by a hinge bolt 11.
[0055] After the measuring equipment 17 is housed in the rear compartment 16, the equipment and the transition platform 6 can be secured a second time to improve the stability and reliability of the measuring equipment 17 during transportation. Specifically, in this embodiment, the rear of the transition platform 6 is fixedly connected to the bottom wall of the rear compartment 16 by hinge bolts 11.
[0056] During unloading, the hinge bolt 11 is first loosened, and then the horizontal drive mechanism 18 drives the pull-out bracket 1 to move backward along the slide rail 3, moving the lifting bracket 5 and the transition platform 6 out of the rear compartment 16. During loading, as the vehicle 15 moves backward, the transition platform 6 gradually reaches above a pair of support rods 12, and the guide pin 10 automatically aligns and inserts into the guide hole, thus restricting the transition platform 6.
[0057] In a preferred embodiment, in the electric loading and unloading device for the vehicle's rear compartment, the horizontal drive mechanism 18 is an electric push rod; the lifting drive mechanism 8 is an electric winch. The electric winch is connected to the crossbar 9 at the lower part of the lifting bracket 5 via a steel wire rope 4.
[0058] In a preferred embodiment, the electric loading and unloading device for the rear compartment of a vehicle further includes a control module connected to the horizontal drive mechanism 18 and the lifting drive mechanism 8.
[0059] The loading and unloading process of the measuring equipment 17 can be achieved through one-button control and electric operation. Furthermore, the loading and unloading process can be stopped at any position.
[0060] In a preferred embodiment, the electric loading and unloading device for the rear compartment of the vehicle is powered by the vehicle's power supply.
[0061] In one specific embodiment, the electric loading and unloading device provided by this utility model mainly consists of an electric push rod, an electric winch, a pull-out bracket, a lifting bracket, a transition platform, leveling feet, slide rails, turnbuckles, etc. Loading and unloading the measuring equipment involves two main actions: horizontal movement and lifting movement. These can be stopped at any position and can be achieved through electric operation or one-button control. When the measuring equipment needs to be unloaded, the vehicle reaches the predetermined point. First, the pull-out bracket is unlocked. Holding the control handle, the pull-out bracket, lifting bracket, and measuring equipment are pushed out of the rear compartment via the extension rod of the electric push rod using one-button control. Then, the lifting bracket and measuring equipment are smoothly placed on the ground using the electric winch. The bolts connecting the transition platform to the upper and lower brackets are released. The leveling feet support the transition platform, and the measuring equipment is lifted off the lifting bracket via the transition platform, allowing the vehicle to drive away. The four leveling feet level the measuring equipment, enabling operation. When the measuring equipment needs to be loaded, the unloading and landing process is reversed. When the vehicle's power supply is insufficient or malfunctions, the measuring equipment can also be moved horizontally by manually pulling out the bracket and raised and lowered by manually cranking the electric winch, thus enabling loading and unloading of the measuring equipment.
[0062] The electric loading and unloading device provided by this utility model has the following beneficial effects: it realizes the loading and unloading of large measuring equipment based on electric operation, eliminating manual labor. In actual application, it can reduce labor costs by more than half, and is safer, more convenient and more efficient.
[0063] In addition, this device has the following features: its dimensions can be specifically designed according to the rear compartment space of a vehicle; its power comes from the vehicle's own power supply, making it suitable for retrofitting existing vehicles. The measuring equipment can be controlled electrically with a single button during loading and unloading, and can be stopped at any position. The device can also be switched to manual operation mode. Components such as the electric winch and leveling feet can be selected from existing products, ensuring a fast production and supply cycle. The pull-out bracket and electric push rod are mature structures, guaranteeing their reliability.
[0064] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
