Description

Technical Field

[0001] This utility model belongs to the field of optical measurement equipment technology, and in particular relates to a pickup truck optical measurement vehicle body locking device. Background Technology

[0002] Optical surveying technology helps geologists identify rock types and analyze mineral composition. Through lidar and photogrammetry, it acquires high-precision topographic data, aiding in geological structure analysis and geological disaster early warning. In municipal engineering inspections, optical surveying is used to detect road smoothness and bridge structural deformation, ensuring infrastructure safety. During road mapping, it can quickly obtain information such as road planar position and elevation, creating accurate maps and providing a basis for traffic planning and construction. In these field operation scenarios, pickup trucks, with their unique advantages, have become the ideal choice for carrying optical surveying equipment. They not only possess flexible mobility, easily traversing various complex terrains, but also have ample cargo space, providing a stable platform for optical surveying equipment. The optical surveying equipment is integrated into a modular container, which is then secured to the pickup truck's cargo box using locking devices, forming a mobile surveying workstation.

[0003] Currently, the horizontal displacement of the container is limited by lateral clamping blocks, but no locking structure is set for the vertical direction. When the pickup truck is driving on rough roads, the container is prone to vertical jumping, causing the bottom of the container to repeatedly collide with the base. This may not only damage the positioning structure at the bottom of the container, but also transmit vibrations to the internal optical equipment, affecting the measurement accuracy of the equipment.

[0004] To address these issues, we provide a pickup truck optical measurement vehicle cabin locking device. Utility Model Content

[0005] The purpose of this utility model is to provide a locking device for the vehicle body of an optical measurement vehicle in a pickup truck. Through the cooperation of the bracket, the container and the fastening mechanism, it solves the problem that in the prior art, the vehicle body does not have a locking structure for the vertical direction. When the pickup truck is driving on rough roads, the container is prone to vertical jumping, which causes the bottom of the container to repeatedly collide with the base, affecting the measurement accuracy of the equipment.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a locking device for a pickup truck's optical measurement vehicle cabin, comprising a vehicle body. A bracket is mounted on one side of the top of the vehicle body, and a container is fixedly connected to the top of the bracket. A fastening mechanism is located at the bottom of the bracket, comprising a connecting plate. One side of the connecting plate is fixedly connected to the bracket, and a positioning plate is fixedly connected to the surface of the connecting plate. A housing is fixedly connected to both sides of the vehicle body surface. A motor is fixedly connected to the bottom of one side of the inner cavity of the housing. A threaded rod is fixedly connected to the output end of the motor. One side of the threaded rod is movably connected to the inner wall of the housing via a bearing. A thread is present on one side of the surface of the threaded rod. A threaded sleeve is connected, with a limiting rod fixedly connected to the top of the threaded sleeve. The bottom of the positioning plate extends into the inner cavity of the outer shell. A limiting groove is formed on one side of the positioning plate to cooperate with the limiting rod. When the cabin needs to be locked, the motor starts and drives the threaded rod to rotate. The external thread of the threaded rod cooperates with the internal thread of the threaded sleeve, driving the threaded sleeve to move towards the positioning plate along the axis of the threaded rod. The limiting rod at the top of the threaded sleeve moves synchronously and finally inserts into the limiting groove on one side of the positioning plate. The cooperation between the limiting rod and the limiting groove restricts the longitudinal displacement of the positioning plate, and thus restricts the longitudinal displacement of the connecting plate and the bracket, preventing the bracket from moving longitudinally along the vehicle body. At the same time, the cooperation between the positioning plate and the inner cavity of the outer shell restricts the lateral displacement of the positioning plate, and the lateral displacement of the connecting plate and the bracket is also restricted. Ultimately, the cabin is locked in both directions on the vehicle body, ensuring that the cabin will not experience longitudinal or lateral displacement during vehicle movement and ensuring the stability of the reference position of the internal optical measuring equipment.

[0008] The present invention is further configured such that a positioning hole is provided on one side of the top of the outer shell, and the bottom of the positioning plate extends into the inner cavity of the outer shell through the positioning hole. The gap between the positioning hole and the positioning plate restricts the lateral swaying of the positioning plate, further enhancing the stability of the positioning plate and indirectly improving the overall stability of the bracket and the cabin, thus preventing the cabin from shifting due to the swaying of the positioning plate.

[0009] The present invention is further configured such that a sliding groove is provided at the bottom of the outer shell, and a slider is fixedly connected to the bottom of the threaded sleeve. The slider is slidably connected to the sliding groove. The sliding cooperation between the slider and the sliding groove provides guidance for the movement of the threaded sleeve, restricting the threaded sleeve to move only along the axis of the sliding groove, avoiding radial shaking or offset of the threaded sleeve under the drive of the threaded rod, and ensuring that the limiting rod at the top of the threaded sleeve can always be aligned with the limiting groove of the positioning plate.

[0010] The present invention is further configured such that each of the four corners of the inner cavity of the bracket is fixedly connected to a support block, the top of the support block is fixedly connected to the container, and the support blocks distributed at the four corners form a multi-point uniform support for the container, which can distribute the weight of the container to the four corners of the bracket, and avoid the weight of the container being concentrated on a certain area of ​​the bracket, causing local deformation of the bracket.

[0011] The present invention is further configured such that hydraulic struts are fixedly connected to the surface of the container, and the number of hydraulic struts is four. The hydraulic struts are symmetrically arranged, and the four symmetrically distributed hydraulic struts can extend synchronously through hydraulic drive after the container is unlocked from the bracket, providing stable four-point support for the container, so that the container can be placed directly and stably on the ground.

[0012] The present invention is further provided that each of the four corners of the surface of the connecting plate is provided with a first fastener, and the connecting plate is fixedly connected to the bracket by the first fastener. The first fastener can fix the connecting plate and the bracket, forming a uniform connection force point, and avoiding loose gaps between the connecting plate and the bracket.

[0013] The present invention is further provided that the surface of the outer shell is provided with a second fastener, and the outer shell is fixedly connected to the vehicle body through the second fastener. The second fastener can fix the outer shell to the surface of the vehicle body, ensuring that the outer shell does not shift or shake during the driving of the pickup truck.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a motor to drive the threaded sleeve and the limiting rod to move, so that the limiting rod automatically inserts into the limiting groove of the positioning plate to complete the longitudinal locking. Combined with the lateral constraint of the positioning plate and the outer shell, the vertical limitation of the positioning hole and the positioning plate, and the guiding limitation of the slider and the slide groove, a comprehensive locking structure is formed, which effectively resists the impact generated by the pickup truck when it bumps on rough roads, brakes suddenly or turns sharply, limits the displacement and shaking of the cabin, and ensures the stability of the internal optical measurement equipment.

[0016] 2. This utility model uses hydraulic struts that automatically extend after unlocking to directly lift the container and stably support it on the ground. There is no need to carry or set up additional support tools, eliminating the cumbersome support setup steps during field operations. Furthermore, the hydraulic struts can flexibly adjust the support height, and even in uneven ground environments, the container's levelness can be quickly calibrated to meet the strict requirements of optical measuring equipment for operating benchmarks, thus shortening the conversion process from vehicle-mounted to operational status.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1-6 This utility model is a locking device for the cabin of a pickup truck optical measurement vehicle, including a vehicle body 1. A bracket 2 is provided on one side of the top of the vehicle body 1. A container 3 is fixedly connected to the top of the bracket 2. A fastening mechanism 4 is provided at the bottom of the bracket 2. The fastening mechanism 4 includes a connecting plate 41. One side of the connecting plate 41 is fixedly connected to the bracket 2. A positioning plate 42 is fixedly connected to the surface of the connecting plate 41. Both sides of the surface of the vehicle body 1 are fixedly connected to a shell 43. A motor 44 is fixedly connected to the bottom of one side of the inner cavity of the shell 43. A threaded rod 45 is fixedly connected to the output end of the motor 44. One side of the threaded rod 45 is movably connected to the inner wall of the shell 43 through a bearing. A threaded sleeve 46 is threadedly connected to one side of the surface of the threaded rod 45. A limit rod 47 is fixedly connected to the top of the threaded sleeve 46. The bottom of the positioning plate 42 extends into the inner cavity of the shell 43. A limit groove 48 is provided on one side of the positioning plate 42 to cooperate with the limit rod 47.

[0027] Specifically: When it is necessary to lock the cabin 3, the motor 44 starts and drives the threaded rod 45 to rotate. The motor 44 is model K107DV90L4. The external thread of the threaded rod 45 engages with the internal thread of the threaded sleeve 46, driving the threaded sleeve 46 to move towards the positioning plate 42 along the axis of the threaded rod 45. The limiting rod 47 at the top of the threaded sleeve 46 moves synchronously and finally inserts into the limiting groove 48 on one side of the positioning plate 42. The engagement of the limiting rod 47 and the limiting groove 48 restricts the longitudinal displacement of the positioning plate 42, thereby restricting the longitudinal displacement of the connecting plate 41 and the bracket 2, preventing the bracket 2 from moving longitudinally along the vehicle body 1. At the same time, the engagement of the positioning plate 42 with the inner cavity of the outer shell 43 restricts the lateral displacement of the positioning plate 42. The lateral displacement of the connecting plate 41 and the bracket 2 is also restricted, ultimately achieving bidirectional locking of the cabin 3 on the vehicle body 1. This ensures that the cabin 3 will not experience longitudinal or lateral displacement during the movement of the vehicle body 1, guaranteeing the stability of the reference position of the internal optical measuring equipment.

[0028] A positioning hole 5 is provided on one side of the top of the outer shell 43. The bottom of the positioning plate 42 extends into the inner cavity of the outer shell 43 through the positioning hole 5. A sliding groove 6 is provided at the bottom of the outer shell 43. A slider 7 is fixedly connected to the bottom of the threaded sleeve 46. The slider 7 is slidably connected to the sliding groove 6. Support blocks 8 are fixedly connected to the four corners of the inner cavity of the bracket 2. The top of the support blocks 8 is fixedly connected to the container 3. Hydraulic struts 9 are fixedly connected to the surface of the container 3. There are four hydraulic struts 9, which are symmetrically arranged. First fasteners are provided at the four corners of the surface of the connecting plate 41. The connecting plate 41 is fixedly connected to the bracket 2 through the first fasteners. Second fasteners are provided on the surface of the outer shell 43. The outer shell 43 is fixedly connected to the vehicle body 1 through the second fasteners.

[0029] Specifically: the clearance fit between the positioning hole 5 and the positioning plate 42 restricts the lateral sway of the positioning plate 42, further enhancing the stability of the positioning plate 42, and indirectly improving the overall stability of the bracket 2 and the cabin 3, preventing the cabin 3 from shifting due to the sway of the positioning plate 42. The sliding fit between the slider 7 and the slide groove 6 provides guidance for the movement of the threaded sleeve 46, restricting the threaded sleeve 46 to move only along the axis of the slide groove 6, preventing the threaded sleeve 46 from swaying or shifting radially under the action of the threaded rod 45, and ensuring that the limiting rod 47 at the top of the threaded sleeve 46 can always be aligned with the limiting groove 48 of the positioning plate 42. The four corner blocks 8 form multi-point uniform support for the cabin 3, which can hold the cabin 3... The weight is distributed to the four corners of the bracket 2, preventing the weight of the container 3 from being concentrated on a certain area of ​​the bracket 2 and causing local deformation of the bracket 2. The four symmetrically distributed hydraulic struts 9 can be used with GCD-80 hydraulic struts to extend synchronously through hydraulic drive after the container 3 is unlocked from the bracket 2, providing stable four-point support for the container 3, so that the container 3 can be placed directly and stably on the ground. The first fastener can fix the connecting plate 41 to the bracket 2, forming a uniform connection force point, and preventing loose gaps between the connecting plate 41 and the bracket 2. The second fastener can fix the outer shell 43 to the surface of the vehicle body 1, ensuring that the outer shell 43 does not shift or shake during the pickup truck's operation.

[0030] The working principle of this utility model is as follows: The motor 44 is started, and the motor 44 drives the threaded rod 45 to rotate. Under the action of thread transmission, the threaded sleeve 46 moves towards the positioning plate 42 along the axis of the threaded rod 45. The slider 7 slides along the slide groove 6 at the bottom of the outer shell 43. The slide groove 6 provides guidance for the slider 7, restricting the threaded sleeve 46 to move only in a fixed direction, avoiding radial shaking of the threaded sleeve 46 that would cause the limiting rod 47 to deviate. The limiting rod 47 moves synchronously with the threaded sleeve 46 and is inserted into the limiting groove 48. The cooperation between the limiting rod 47 and the limiting groove 48 directly restricts the longitudinal displacement of the positioning plate 42, ensuring that the container 3 has no displacement or shaking when the vehicle body 1 is moving, and ensuring the stability of the reference position of the internal optical measuring equipment.

[0031] When it is necessary to unlock the container 3 from the vehicle body 1 and carry out measurement work, the motor 44 starts in reverse, driving the threaded rod 45 to rotate in reverse. The threaded sleeve 46 moves away from the positioning plate 42 along the axis of the threaded rod 45, and the limiting rod 47 disengages from the limiting groove 48, releasing the longitudinal limit on the positioning plate 42. The positioning plate 42 is removed from the positioning hole 5, the container 3 separates from the vehicle body 1, and the hydraulic strut 9 extends synchronously through hydraulic drive, contacting the ground at the bottom and forming a four-point support, stabilizing the container 3. The operator adjusts the height of the hydraulic strut 9 according to the flatness of the field ground to keep the container 3 level and meet the operating reference requirements of the optical measurement equipment.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
