DETAILED DESCRIPTION

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 7 As shown, a refrigeration equipment installation device for a cold chain logistics project is characterized by comprising a main body 1 of a vehicle and a first installation component 37 for fixing a refrigeration unit 5, wherein the first installation component 37 is disposed at the front end of the interior of the main body 1 of the vehicle.

[0030] The first mounting component 37 includes a base 2 and a support 3. The support 3 is connected to the top of the base 2 by a plurality of spring shock absorbers 4. The refrigeration unit 5 is fixed on the support 3. Fixed seats 6 are evenly distributed around the top surface of the base 2. A plurality of adjustment components are arranged on the inner end face of each fixed seat 6 along its height direction. The adjustment component includes a spring plug 7 and a connecting rod 8. The connecting rod 8 is assembled on the fixed seat 6 and the spring plug 7 is connected to the connecting rod 8. The side of the support 3 is provided with a matching socket 9 corresponding to the position of each spring plug 7. A power component is provided on the fixed seat 6. The power component is used to synchronously push all the spring plugs 7 on the same horizontal plane to insert or leave the socket 9, so as to change the elastic support force of the support 3.

[0031] The elastic insert 7 includes a connecting plate 10, a fixed plate 11, and a movable plate 12. The fixed plate 11 is fixedly disposed at the bottom of the front end face of the connecting plate 10. The movable plate 12 is slidably assembled on the front end face of the connecting plate 10. A miniature spring shock absorber 13 is connected between the fixed plate 11 and the movable plate 12. The rear end face of the connecting plate 10 is mounted on the connecting rod 8.

[0032] In the embodiment, the power assembly comprises a plurality of connecting pipes 20 and a plurality of control valves 21, a plurality of moving cavities 22 corresponding to the connecting rods 8 are formed in the fixed seat 6, the connecting rods 8 slide through the moving cavities 22, one end of the connecting rods 8 extends to the outside of the fixed seat 6 and is connected with the elastic plug 7, the other end of the connecting rods 8 is connected with the sealing element 23, the reset spring 24 is connected between the connecting rod 8 and the inner wall of the moving cavity 22, the moving cavities 22 in the same horizontal plane are connected in communication through the connecting pipes 20, and a plurality of control valves 21 are arranged on one of the fixed seats 6, one end of the control valve 21 is connected with the corresponding connecting pipe 20, and the other end of the control valve 21 is connected with the external air source, the connecting pipe 20 can be connected with high-pressure fluid, so as to synchronously push all the elastic plugs 7 in the same horizontal plane to insert into the sockets 9, and the millimeter wave radar is arranged at the front end of the carriage main body 1, so as to identify the road surface condition in front and transmit a signal to the processor, and the processor is electrically connected with the control valve 21 and the external air source;

[0033] When the control valve 21 is opened, the external air source connects high-pressure gas into the connecting pipe 20, the high-pressure gas pushes the connecting rod 8 after entering the moving cavity 22, so that the movable plate 12 of the elastic plug 7 and the fixed plate 11 are integrally inserted into the socket 9, after being inserted, the movable plate 12 is in contact with the inner wall of the socket 9, the micro spring shock absorber 13 is compressed, and the superposition effect of rigid support and elastic buffer is formed, so as to improve the local rigidity of the support 3; and after the control valve 21 releases the pressure, the reset spring 24 pulls the connecting rod 8 to retract, and the elastic plug 7 exits the socket 9, and only the spring shock absorber 4 between the base 2 and the support 3 is reserved as a first-stage buffer.

[0034] When the elastic plug 7 is inserted into the socket 9, the micro spring shock absorber 13 of the elastic plug 7 and the spring shock absorber 4 of the base 2 form a parallel structure, so that the total rigidity of the spring of the support 3 is equal to the sum of the rigidity of the spring shock absorber 4 and the micro spring shock absorber 13, and the elastic plug 7 is uniformly distributed along the circumference of the support 3, so that the weight of the equipment is dispersed to multiple support points, the single spring is prevented from being overloaded and failed, and the elastic plugs 7 inserted into different positions can compensate for the uneven deformation of the support 3 (such as lateral force when the vehicle turns).

[0035] The spring shock absorber 4 realizes the preliminary damping of the support 3 and the base 2, and the cooperation of the elastic plug 7 and the socket 9 forms a second-stage buffer, in working, the millimeter wave radar monitors the road condition in front in real time (such as the degree of bumping), the processor controls the power assembly to synchronously insert a plurality of elastic plugs 7, a rigid frame is formed, the vibration transmission rate is reduced, the elastic plugs are withdrawn in a gentle road section, the flexible damping is restored, and the energy consumption is reduced.

[0036] It can also be adaptively adjusted according to the load of the refrigeration unit 5 installed on it. For example, when the weight of the refrigeration unit 5 changes suddenly (such as when the refrigerant is fully loaded), causing the support 3 to collapse, all the spring blocks 7 are inserted to increase the total rigidity and keep the equipment level error ≤0.5°. In the case of no-load transportation or low-power operation, some of the spring blocks 7 are removed to reduce rigidity and reduce energy consumption.

[0037] Here are some application examples in various scenarios:

[0038] 1. Heavy-duty transportation scenario: With all the elastic plugs 7 inserted, the overall stiffness of the support 3 is increased to 1500 N / mm, which can withstand the impact of peak acceleration 5G, and the equipment displacement is controlled within ±2 mm.

[0039] 2. Long-distance cold chain transportation: When cruising on flat roads, only 50% of the spring-loaded blocks 7 are used, reducing the overall energy consumption of the shock absorption system by 30% and the equipment operating noise ≤65 dB;

[0040] 3. Emergency braking or curve conditions: After millimeter-wave radar prediction, the spring block 7 is fully inserted within 0.2 seconds, increasing the lateral support force by 200% to prevent the refrigeration unit 5 from overturning.

[0041] In this embodiment, the first mounting component 37 further includes a base 14, on which the base 2 is movably disposed. The base 14 is mounted on the carriage body 1. Each side end face of the base 2 is provided with a plurality of support rings 15. Adjustment seats 16 are evenly distributed around the top surface of the base 14. A motor 17 is disposed in one end of the adjustment seat 16. A spool 18 is disposed on the output shaft of the motor 17. An elastic rope 19 is disposed on the spool 18. The other end of the elastic rope 19 passes through each support ring 15 on the same side and is fixed to the other end of the adjustment seat 16. The rotation of the spool 18 can wind and unwind the elastic rope 19, thereby adjusting the tension of the elastic rope 19.

[0042] The base 2 is connected to the base 14 via multiple highly elastic ropes 19. The motor 17 drives the reel 18 to wind up and unwind the ropes, dynamically adjusting the tension. When the carriage turns or tilts, the elastic rope 19 on the stressed side is tightened while the opposite side is loosened, creating a reverse torque to counteract the offset of the base 2 caused by inertial force. Compared to traditional rigid connections, this avoids stress concentration caused by rigid connections and balances the lateral sway generated during carriage movement. Furthermore, the flexible connection of the elastic ropes 19 can withstand 8G instantaneous impact (such as sudden braking), while rigid fixation is prone to bolt breakage or weld cracking due to rigid transmission.

[0043] Meanwhile, when the weight of the refrigeration unit 5 changes, the system automatically adjusts the preload of the elastic rope 19 to ensure that the base 2 is always in a horizontal state, avoiding equipment tilting or resonance due to uneven load.

[0044] In the embodiment, a second mounting assembly for fixing the goods 36 is also included, which is arranged in the compartment main body 1; the second mounting assembly includes a transportation mechanism and a heat insulation mechanism, the transportation mechanism includes a pair of lower slide rods 25, a pair of upper slide rods 26 and a driving mechanism, the top end and the bottom end of the compartment main body 1 are respectively provided with upper slide grooves and lower slide grooves corresponding to the upper slide rods 26 and the lower slide rods 25, the upper slide rods 26 and the lower slide rods 25 are respectively embedded in the upper slide grooves and the lower slide grooves, a plurality of lower slide seats 27 are slidably connected between the two lower slide rods 25, a plurality of corresponding upper slide seats 28 are slidably connected between the two upper slide rods 26, a plurality of supporting pieces 29 are connected between the corresponding upper slide seats 28 and the lower slide seats 27, and the goods 36 can be placed on the front side of the supporting pieces 29; the driving mechanism is arranged on the top of the compartment main body 1, and the upper slide seats 28 are selectively connected with the driving mechanism, so that the upper slide seats 28 and the lower supporting pieces 29 and the lower slide seats 27 are driven to move horizontally by the driving mechanism, to push the goods 36 to move outward; the heat insulation mechanism includes a plurality of heat insulation plates 30, each of the heat insulation plates 30 is distributed on the left side and the right side inside the compartment main body 1, and the heat insulation plates 30 are rotatably installed on the compartment main body 1.

[0046] When the belt transmission mechanism 31 is in a running state during unloading, the electromagnet 33 on the upper slide seat 28 corresponding to the goods 36 to be pushed to the compartment door of the compartment main body 1 is electrified to adsorb the iron block 32, so that the upper slide seat 28 is driven to move horizontally along with the running of the belt transmission mechanism 31, to realize automatic pushing of the goods 36, and the worker can complete the unloading without entering the compartment.

[0047] In the embodiment, the support is an elastic band, the upper slide 28 and the lower slide 27 are provided with a plurality of corresponding installation openings 34, the installation openings 34 are provided with support rods 35, and the elastic band is sleeved on the upper and lower corresponding support rods 35; the elastic band is used to realize one-way pushing of the goods 36, the elastic band is taken off after the goods 36 in front of the elastic band are taken away, so that the elastic band does not affect the goods 36 behind; conversely, when the goods are loaded, the elastic band is sleeved between the upper slide 28 and the lower slide 27, and then the goods 36 are placed in front, the goods 36 are continuously placed, extrusion force is generated, the goods 36 in place are gradually displaced to the inside of the vehicle compartment main body 1, and during loading, the goods 36 are placed in front of the same support 29 according to the unloading place of the goods 36.
