Description

Technical Field

[0001] The utility model relates to the technical field related to traffic edge computing devices, and specifically, to a smart box suitable for traffic detection. Background Art

[0002] The edge computing box enables local AI computing capabilities to be very strong. The edge computing box is located between the traditional cloud and the terminal. It can greatly alleviate the pressure of network communication. The data generated by autonomous driving can be responded to and processed in real time in the car. The key to edge computing is to use processor chips with high computing power and high-performance storage systems.

[0003] my country's utility model patent "A vehicle-road collaborative edge computing server" with publication number CN218512907U discloses a vehicle-road collaborative edge computing server, including: a shell, which is the main outer frame mounting structure of the device, a mounting frame is arranged inside the shell, and positioning holes are preset on the inner surfaces of the left and right ends of the shell; a top cover, located at the top of the shell, a heat sink is arranged on the top surface of the top cover, a sealing strip is arranged at the connection end between the top cover and the shell, and silicone grease is arranged on the inner surface of the top cover; a base, located at the bottom of the shell, a compression spring is arranged between the base and the mounting frame; a guide plate, located at the bottom of the top cover, and a movable rod is connected inside the guide plate. The base supports the entire device, and at the same time cooperates with the spring to slide vertically inside the mounting frame, which can play a role of vertical buffering for the entire device, and the position distribution is symmetrical, the force is more uniform, and the overall safety is further improved.

When the shaking amplitude is large, the impact force between the two during contact is large, which will reduce the service life of the edge computing device. Therefore, it is necessary to design a smart box suitable for traffic detection. Utility Model Content

[0028] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0029] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] like Figure 1-5 As shown, a smart box suitable for traffic detection comprises: a mounting plate 1, an edge computing smart box body 2 mounted on the mounting plate 1, and at least one group of primary shock absorbing units mounted on the mounting plate 1, wherein the primary shock absorbing unit comprises a first mounting frame 3 spaced apart from the mounting plate 1, at least two guide rods 4 fixedly mounted on the mounting plate 1 and the lower ends of which slide through the first mounting frame 3, and a horizontal connecting arm 5 fixedly connected to the lower ends of the two guide rods 4, and each guide rod 4 is sleeved with a first spring 6 for pushing the mounting plate 1 to slide away from the first mounting frame 3;

[0031] The first mounting frame 3 is equipped with a secondary shock absorbing unit, which includes a vertical top rod 7 vertically slidably mounted on the first mounting frame 3 and located directly above the connecting arm 5, a second spring 8 assembled on the first mounting frame 3 through a mounting mechanism and used to push the top rod 7 to slide vertically downward, and a horizontal clamping plate 9 fixedly mounted on the upper end of the top rod 7. A clamping unit that can be clamped with the clamping plate 9 that slides upward to return to its original position is provided on the first mounting frame 3 through a second mounting frame 10, and an unlocking member 11 that matches the clamping unit and is used to separate the clamping unit from the clamping plate 9 is assembled on the mounting plate 1, and the elastic force of the second spring 8 is smaller than the elastic force of the first spring 6.

[0032] When subject to bumps, the guide rod 4 will slide on the first mounting frame 3, and the first spring 6 is used to reduce the sliding times and sliding amplitude of the guide rod 4 to play a shock-absorbing role; however, when the bump amplitude is large, the mounting plate 1 will move downward and drive the unlocking member 11 to contact the card unit, so that the card unit is separated from the card plate 9. After the card unit is separated from the card plate 9, the second spring 8 will push the top rod 7 to slide vertically downward.

[0033] When bumped, the guide rod 4 slides downward, and the first spring 6 is further compressed at this time. The first spring 6 plays a shock-absorbing role, and the speed of the mounting plate 1 gradually decreases when it moves downward; when the speed of the mounting plate 1 sliding downward returns to zero, the potential energy stored in the first spring 6 will push the mounting plate 1 to slide upward, and the speed of the mounting plate 1 sliding upward will gradually increase, which will cause the connecting arm 5 to collide with the first mounting frame 3. Therefore, a secondary shock-absorbing unit is provided, and the connecting arm 5 will contact the top rod 7 before contacting the first mounting frame 3. The connecting arm 5 will push the top rod 7 to slide upward, and the second spring 8 will be further compressed. The second spring 8 will slow down the speed of the connecting arm 5 moving upward, thereby reducing the speed of the connecting arm 5 when it collides with the first mounting frame 3.

[0034] Because the elastic force of the second spring 8 is smaller than the elastic force of the first spring 6, the second spring 8 cannot push the connecting arm 5 to slide vertically downward through the push rod 7, but the push rod 7 can buffer the connecting arm 5 and slow down the moving speed and amplitude of the connecting arm 5 to reduce the speed when the connecting arm 5 collides with the first mounting frame 3 and the noise caused by the collision.

[0035] The clamping unit includes a plurality of guide sleeves 12 arranged at intervals along the radial direction of the clamping plate 9 and fixedly mounted on the second mounting frame 10, a horizontal slide arm 13 sliding through the plurality of guide sleeves 12, a wedge-shaped clamping block 14 mounted on the end of the slide arm 13 close to the clamping plate 9, a first stopper 15 located between two adjacent guide sleeves 12 and fixedly mounted on the slide arm 13, a third spring 16 sleeved on the slide arm 13 and having an end close to the clamping plate 9 abutting against the first stopper 15, and a pulley 17 mounted on the first stopper 15 through a mounting member and located above the slide arm 13 and capable of slidingly contacting the unlocking member 11;

[0036] The unlocking member 11 is located on one side of the pulley 17 close to the axis of the clamping disk 9. The unlocking member 11 is in a vertical cylindrical shape. A truncated cone portion is protruded from the lower end of the unlocking member 11. The diameter of the lower end of the truncated cone portion is smaller than the diameter of the upper end of the truncated cone portion.

[0037] When the mounting plate 1 slides downward, the unlocking member 11 is driven to slide downward. After the unlocking member 11 moves downward for a distance, the side wall of the conical portion contacts the pulley 17 first. The mounting plate 1 continues to drive the unlocking member 11 to slide downward. The conical portion will squeeze the pulley 17 to move away from the axis of the card plate 9. The pulley 17 will drive the first limit member 15 and the slide arm 13 to slide away from the card plate 9 through the mounting component, so that the wedge-shaped block 14 is separated from the card plate 9, and the second spring 8 can push the push rod 7 to slide downward.

[0038] When the mounting plate 1 returns to its original position, the unlocking member 11 is separated from the pulley 17, the third spring 16 pushes the wedge-shaped block 14 back to its original position, and the connecting arm 5 pushes the push rod 7 to slide upward to return to its original position, driving the clamping plate 9 to slide upward and pass over the wedge-shaped block 14, so that the clamping plate 9 and the side of the wedge-shaped block 14 away from the first mounting frame 3 are in conflict.

[0039] The mounting component includes a mounting sleeve fixedly connected to the first limit member 15, a vertical adjustment rod 18 vertically sliding through the mounting sleeve, and a locking bolt threadedly mounted on the mounting sleeve and with its end abutting against the adjustment rod 18. The pulley 17 is mounted on the upper end of the adjustment rod 18.

[0040] The installation component can be used to adjust the distance between the unlocking member 11 and the pulley 17 when the mounting plate 1 returns to its original position. The smaller the distance between the pulley 17 and the unlocking member 11, the smaller the shaking amplitude of the mounting plate 1 when driving the unlocking member 11 to contact the pulley 17; the larger the distance between the pulley 17 and the unlocking member 11, the larger the shaking amplitude of the mounting plate 1 when driving the unlocking member 11 to contact the pulley 17.

[0041] By loosening the locking bolt, the adjusting rod 18 can slide on the mounting sleeve, thereby adjusting the distance between the pulley 17 and the unlocking member 11. After the adjustment is completed, the locking bolt is tightened.

[0042] The mounting mechanism includes a mounting tube 19 with an open end facing downward and the open end fixedly mounted on the second mounting frame 10, a horizontal limit plate 20 fixedly mounted on the lower end of the push rod 7, and a second limit member 21 fixedly mounted on the upper end of the push rod 7 and capable of contacting the top of the mounting tube 19. The upper end of the push rod 7 vertically slides through the inner top of the mounting tube 19, and the two ends of the second spring 8 respectively contact the limit plate 20 and the inner top of the mounting tube 19. The clamping plate 9 is located above the limit plate 20.

[0043] After the wedge-shaped clamping block 14 is separated from the clamping plate 9 , the second spring 8 drives the push rod 7 to slide downward by pushing the limiting plate 20 until the second limiting member 21 contacts the top of the installation cylinder 19 .

[0044] The lower surface of the limiting plate 20 is flush with the lower end of the push rod 7 , and the lower surface of the limiting plate 20 is equipped with a first rubber pad.

[0045] The top of the installation tube 19 is provided with a sleeve portion sleeved on the outside of the push rod 7 , and an annular flange 22 is coaxially protruded on the top outer wall of the sleeve portion, and a second rubber pad 23 is provided on the upper surface of the annular flange 22 .

[0046] The first rubber pad and the second rubber pad 23 have the same function of reducing the noise generated during contact.

[0047] The edge computing smart box body 2 includes:

[0048] A core processing module, used for receiving raw data transmitted by roadside sensors, and preprocessing all or part of the raw data to obtain semantic data;

[0049] A wireless communication module, connected to the core processing module, for transmitting the semantic data and unprocessed raw data to a host computer;

[0050] The communication network port is connected to the core processing module and is used to connect to a wired transmission line to achieve wired communication between the core processing module and a host computer.

However, the present invention is not limited to the specific details in the above embodiments.
