Description

Technical Field

[0001] This invention relates to the field of microwave radar technology, and specifically to a shock-resistant microwave radar mounting bracket. Background Technology

[0002] Radar is a transliteration of the English word "radar," which is an abbreviation of "radio detection and ranging." It refers to the use of radio waves to detect targets and determine their spatial location. Therefore, radar is also known as "radio positioning."

[0003] Microwave radar is an electronic device that uses microwaves to detect targets. The radar emits microwaves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the microwave emission point, the rate of change of distance (radial velocity), azimuth, and altitude. When using radar, it needs to be installed and fixed with a mounting bracket. Traditional mounting brackets do not have shock absorption functions. For some radars installed on vehicles, the vibrations from uneven ground during vehicle movement can easily damage the internal components of the radar. Summary of the Invention

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a shock-resistant microwave radar mounting bracket, which can effectively solve the problem that the existing mounting brackets do not have the function of shock absorption, and the radar internal components are easily damaged by the vibration of uneven ground during vehicle driving.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides a shock-resistant microwave radar mounting bracket, including a mounting structure. The mounting structure includes a fixing plate, an upper clamping plate detachably connected to the bottom of the fixing plate, and a lower clamping plate arranged parallel to the bottom of the upper clamping plate. The outer edges of the upper and lower clamping plates are connected by multiple locking bolts. The space between the upper and lower clamping plates forms a mounting cavity for placing a signal receiving module. A microwave radar body is connected to the bottom of the lower clamping plate. A sleeve is integrally formed on the top of the fixing plate, and multiple locking elements are provided on the outer periphery of the sleeve for locking.

[0009] A shock-absorbing structure includes a protective cylinder, a heat-conducting baffle is provided in the middle of the protective cylinder, and a piston that slides with the heat-conducting baffle is provided inside the protective cylinder; a vertically arranged vertical shaft is fixedly provided in the middle of the piston, the lower end of the vertical shaft passes through the heat-conducting baffle and extends into the sleeve and connects with the sleeve, and the upper end of the vertical shaft passes through the protective cylinder and extends out of the protective cylinder; a shock-absorbing spring is fitted on the outside of the vertical shaft between the piston and the heat-conducting baffle.

[0010] In use, first, the protective sleeve is placed on one side of the car bumper. Then, the vertical shaft is passed through the pre-drilled hole in the bumper and extended to the other side. The sleeve is then inserted into one end of the vertical shaft and locked in place, thus quickly and easily installing the microwave radar body. Installation is quick, simple, and saves time and effort. Furthermore, due to the heat-conducting baffle, the protective sleeve is divided into two cavities. The upper cavity engages with the piston, allowing the microwave radar body to move downwards when the vehicle vibrates. This causes the vertical shaft and piston to move downwards, utilizing the heat generated by compressing the air below the piston to dissipate vibrations, achieving initial shock absorption. Simultaneously, the shock-absorbing spring is compressed, generating an upward elastic force, thereby further reducing vibration and preventing excessive vibration from causing collision damage to the microwave radar body. Due to the arrangement of the upper clamping plate, lower clamping plate, and locking bolts, an installation cavity for placing the signal receiving module can be formed. At the same time, due to its overall structural stability, there will be no problem of the signal receiving module being damaged by pressure. Meanwhile, the locking bolts can also prevent collision damage from the outside. In addition, since the upper end of the vertical shaft extends through the protective cylinder to the outside of the protective cylinder, after installation, the sleeve can be moved away from the car bumper by grasping and pressing the vertical shaft. Then, the attitude and orientation of the microwave radar body can be adjusted by rotating the vertical shaft.

[0011] Furthermore, a sliding groove arranged in a front-to-back direction is fixedly provided at the lower end of the lower clamping plate. A slider that slides within the sliding groove is slidably engaged with it. The slider is detachably connected to the microwave radar body by bolts. An adjusting gear is rotatably arranged on the outer side of the sliding groove, and a rack that meshes with the adjusting gear is provided at the upper end of the microwave radar body. Through the arrangement of the sliding groove, slider, adjusting gear, and rack, since the rack meshes with the adjusting gear, the position of the microwave radar body relative to the sliding groove can be shifted by rotating the adjusting gear, thereby further adjusting the attitude of the microwave radar body.

[0012] Furthermore, an inner cylinder coaxially arranged with the protective cylinder is provided below the heat-conducting partition. At least two sets of parallel horizontal plates are fitted around the vertical shaft inside the inner cylinder, each horizontal plate having a guide hole for the vertical shaft to pass through. A mounting plate for installing the control processing module is provided between the horizontal plates, and the upper end of the mounting plate is threadedly connected to the heat-conducting partition. The mounting plate allows the microwave radar's control processing module to be installed inside the protective cylinder, achieving not only impact protection but also effectively preventing water, dust, and other foreign objects from entering the bracket, providing excellent sealing and enabling vehicles equipped with this microwave radar mounting bracket to withstand harsh road conditions such as sandstorms and water crossings. Due to the horizontal plates and guide holes, the vertical shaft can be guided and positioned. Since the mounting plate is fixed at only one end, in a cantilever-like installation manner, the horizontal plates can also limit the lateral swing of the lower end of the mounting plate, thus preventing excessive swing and damage to the control processing module. In addition, in practical applications, the metal inner cylinder provides electrostatic shielding, preventing external magnetic fields from interfering with the control processing module.

[0013] Furthermore, the gap between the protective cylinder and the inner cylinder forms an airflow channel, and the lower end of the protective cylinder is provided with an air inlet communicating with the airflow channel; the heat-conducting baffle is provided with a vent hole communicating with the airflow channel and the cavity below the piston, and the piston is also provided with multiple vertically penetrating vent holes, each of which is provided with a first one-way valve that flows unidirectionally from bottom to top; the upper end of the protective cylinder is provided with an exhaust hole communicating with the cavity above the piston. Through the vent holes and the first one-way valves, when the piston moves downward, the vent holes on the heat-conducting baffle are closed, while the vent holes inside the piston are opened. This allows some gas to pass through the vent holes and then upwards from the piston while keeping the air below the piston compressed, and then be discharged from the exhaust hole. At this time, the vent holes not only serve as damping holes, preventing the piston from rebounding rapidly and causing excessive impact by slowly releasing the pressure below, thus reducing the probability of damage to the microwave radar body, but also allow the air below the piston to absorb some of the heat generated during the operation of the control processing module through the heat-conducting baffle, and also compress and perform work. The method further increases heat, so the venting of overheated air can reduce the operating temperature of the control and processing module inside the inner cylinder and prevent overheating damage. When the piston moves upward, the vent on the heat-conducting baffle opens, while the vent inside the piston closes. At this time, the negative pressure environment in the cavity below the piston allows external cold air to enter from the air inlet and then enter the cavity below the piston through the airflow channel. During this process, the flowing air can carry away some heat through the inner cylinder, further reducing the temperature inside the inner cylinder. In addition, the back pressure of the first one-way valve can also further play a damping role, making the piston rebound stably and slowly, achieving the purpose of further shock absorption.

[0014] Furthermore, a dustproof screen is provided at the air inlet, and a baffle of matching size is hinged to the air inlet within the dustproof screen. The inner side of the baffle is connected to the outer side of the inner cylinder via a return spring. The dustproof screen prevents dust from being brought in by the airflow, thus avoiding interference with the control and processing module. The return spring and baffle prevent rainwater from entering without affecting airflow, further ensuring the normal operation of the control and processing module.

[0015] Furthermore, multiple vertically arranged guide cylinders are evenly distributed above the heat-conducting baffle, and a guide post extending into the upper part of the guide cylinder is correspondingly provided at the lower end of the piston; an airbag in contact with the heat-conducting baffle is provided below the guide post, and the airbag is filled with a volatile liquid medium with a boiling point of 35-55℃. By setting up the airbag, on the one hand, it can further reduce vibration by compressing the airbag when the piston moves downwards during vehicle vibration; on the other hand, by using a volatile liquid medium, since the boiling point of the volatile liquid medium is 35-55℃, when the temperature inside the inner cylinder reaches this range, the liquid medium vaporizes, causing the airbag to expand further, thus generating a greater counterforce, further improving the vibration reduction effect. At the same time, it can also achieve a good cooling effect by absorbing a large amount of heat through the vaporization of the liquid medium itself, avoiding excessively high internal temperatures of the inner cylinder and reducing the reliability of the control processing module.

[0016] Furthermore, the volatile liquid medium is diethyl ether or dichloromethane.

[0017] Furthermore, a cooling fan is installed at the exhaust port, and a magnetic switch for controlling the cooling fan's operation is installed on the upper outer side of the protective cylinder. A sensing plate is installed inside the piston near the magnetic switch, initially positioned below the magnetic switch. Through the magnetic switch and the magnetic sensing plate, when the temperature inside the inner cylinder is too high, the volatile liquid medium inside the air bladder vaporizes and expands, causing the piston to rise and its equilibrium position to shift upwards. This causes the sensing plate to move upwards, allowing the magnetic switch to detect the sensing plate and send a signal to control the cooling fan to start, achieving active cooling and further improving the cooling effect. Additionally, when the cooling fan starts, the gas inside the protective cylinder moves from bottom to top, allowing the lighter hot air to be quickly expelled, and the unidirectional flow of gas prevents the expelled hot air from being re-inhaled, thus avoiding any impact on the cooling effect.

[0018] Beneficial effects

[0019] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0020] 1. The present invention, through the setting of heat-conducting baffle and shock absorption, can divide the protective cylinder into two cavities, so that the upper cavity cooperates with the piston. When the microwave radar body moves downward due to vehicle bumps and vibrations, the microwave radar body drives the vertical axis and piston to move downward. In this way, the heat energy generated by the compressed air below the piston can be used to consume the vibration energy and achieve the purpose of shock absorption.

[0021] 2. By setting up a protective cylinder, the present invention can not only achieve better anti-collision, dustproof and rainproof effects, but also enable the car to better adapt to harsh road conditions such as sandstorms and water crossings.

[0022] 3. Through the modular design of the installation structure and shock absorption structure, this invention can complete the installation and attitude adjustment more quickly and efficiently, saving time and effort and improving work efficiency.

[0023] 4. By incorporating airflow channels, airbags, and volatile liquid media, this invention effectively cools the interior of the inner cylinder, ensuring that the control processing module operates within a dynamically fluctuating and suitable environment, thus preventing excessively high temperatures from affecting the reliability of the control processing module.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] The present invention will be further described below with reference to embodiments.

[0033] Example:

[0034] like Figures 1-5 As shown, a shock-resistant microwave radar mounting bracket includes a mounting structure. The mounting structure includes a fixing plate 3, an upper clamping plate 21 detachably connected to the bottom of the fixing plate 3, and a lower clamping plate 2 arranged parallel to the bottom of the upper clamping plate 21. The outer edges of the upper clamping plate 21 and the lower clamping plate 2 are connected by multiple locking bolts 22. The space between the upper clamping plate 21 and the lower clamping plate 2 forms a mounting cavity for placing a signal receiving module 23. A microwave radar body 1 is connected to the bottom of the lower clamping plate 2. A sleeve 31 is integrally formed on the top of the fixing plate 3, and multiple locking elements 32 for locking are provided on the outer periphery of the sleeve 31.

[0035] The shock-absorbing structure includes a protective cylinder 5, a heat-conducting baffle 6 in the middle of the protective cylinder 5, and a piston 41 that slides within the protective cylinder 5 on the heat-conducting baffle 6. A vertically arranged vertical shaft 4 is fixedly installed in the middle of the piston 41. The lower end of the vertical shaft 4 passes through the heat-conducting baffle 6 and extends into the sleeve 31 and connects with the sleeve 31. The upper end of the vertical shaft 4 passes through the protective cylinder 5 and extends outside the protective cylinder 5. A shock-absorbing spring 61 is fitted around the vertical shaft 4 between the piston 41 and the heat-conducting baffle 6.

[0036] In use, firstly, the protective sleeve 5 is placed over one side of the car bumper. Then, the vertical shaft 4 is passed through the pre-drilled hole on the car bumper and extended to the other side of the bumper. Next, the sleeve 31 is inserted into one end of the vertical shaft 4 and locked in place by the locking piece 32. This quickly and easily installs the microwave radar body 1, saving time and effort. Furthermore, due to the heat-conducting baffle 6, the protective sleeve 5 is divided into two cavities. The upper cavity engages with the piston 41, allowing the microwave radar body 1 to move downwards when the vehicle vibrates. The microwave radar body 1 then moves the vertical shaft 4 and piston 41 downwards, utilizing the heat generated by the compressed air below the piston 41 to dissipate vibrations and achieve initial shock absorption. Simultaneously… The shock-absorbing spring 61 is also compressed, generating an upward elastic force, thereby achieving further shock absorption and preventing excessive vibration from causing collision damage to the microwave radar body 1. Due to the arrangement of the upper clamping plate 21, the lower clamping plate 2, and the locking bolt 22, an installation cavity for placing the signal receiving module 23 can be formed. At the same time, due to its overall structural stability, there will be no problem of the signal receiving module 23 being damaged by pressure. Meanwhile, the locking bolt 22 can also play a role in preventing collision damage from the outside. In addition, since the upper end of the vertical shaft 4 extends through the protective cylinder 5 to the outside of the protective cylinder 5, after installation, the sleeve 31 can be moved away from the car bumper by pressing the vertical shaft 4. Then, the attitude and orientation of the microwave radar body 1 can be adjusted by rotating the vertical shaft 4.

[0037] As an optional solution, the lower clamping plate 2 is fixedly provided with a sliding groove 12 arranged in the front-to-back direction at its lower end. A slider 11 is provided in the sliding groove 12 and slides therewith. The slider 11 is detachably connected to the microwave radar body 1 by bolts. An adjusting gear 13 is rotatably provided on the outer side of the sliding groove 12, and a rack 14 is provided on the upper end of the microwave radar body 1 to mesh with the adjusting gear 13. With the arrangement of the sliding groove 12, slider 11, adjusting gear 13 and rack 14, since the rack 14 meshes with the adjusting gear 13, the position of the microwave radar body 1 relative to the sliding groove 12 can be shifted by rotating the adjusting gear 13, thereby further adjusting the attitude of the microwave radar body 1.

[0038] As an optional solution, an inner cylinder 56 is arranged coaxially with the protective cylinder 5 below the heat-conducting partition 6. At least two sets of parallel horizontal plates 72 are fitted around the vertical shaft 4 inside the inner cylinder 56. Each horizontal plate 72 is provided with a guide hole for the vertical shaft 4 to pass through. An installation plate 71 for installing the control processing module 7 is provided between the horizontal plates 72. The upper end of the installation plate 71 is threaded to the heat-conducting partition 6. The mounting plate 71 allows the microwave radar control processing module 7 to be installed inside the protective cylinder 5, achieving not only impact protection but also effectively preventing water, dust, and other foreign objects from entering the bracket. This excellent sealing allows vehicles equipped with the microwave radar mounting bracket to withstand harsh road conditions such as sandstorms and water crossings. The horizontal plate 72 and guide holes guide and position the vertical axis 4. Since the mounting plate 71 is fixed at only one end, in a cantilever-like installation manner, the horizontal plate 72 also limits the lateral swing of the lower end of the mounting plate 71, preventing excessive swing that could damage the control processing module 7. Furthermore, in practical applications, the metal inner cylinder 56 provides electrostatic shielding, preventing external magnetic fields from interfering with the control processing module 7.

[0039] As an optional solution, the gap between the protective cylinder 5 and the inner cylinder 56 forms an airflow channel 57, and the lower end of the protective cylinder 5 is provided with an air inlet 52 communicating with the airflow channel 57; the heat-conducting baffle 6 is provided with a vent 42 communicating with the airflow channel 57 and the cavity below the piston 41, and the piston 41 is also provided with multiple vertically penetrating vents 42, and each vent 42 is provided with a first one-way valve 43 that flows unidirectionally from bottom to top; the upper end of the protective cylinder 5 is provided with an exhaust port 58 communicating with the cavity above the piston 41. By using the vent 42 and the first one-way valve 43, when the piston 41 moves downward, the vent 42 on the heat-conducting baffle 6 can be closed, while the vent 42 inside the piston 41 can be opened. This allows some gas to pass through the vent 42 and then above the piston 41 while keeping the air below the piston 41 compressed, and then be discharged from the exhaust port 58. At this time, the vent 42 not only serves as a damping orifice, but also prevents the piston 41 from rebounding rapidly and causing excessive impact by slowly releasing the pressure below, thereby reducing the probability of damage to the microwave radar body 1. At the same time, the air below the piston 41 not only absorbs some of the heat generated by the control processing module 7 during operation through the heat-conducting baffle 6, but can also be compressed to do work. The method further increases heat, so the exhaust of overheated air through the vent 42 can reduce the operating temperature of the control processing module 7 inside the inner cylinder 56 and avoid overheating damage; when the piston 41 moves upward, the vent 42 on the heat-conducting baffle 6 opens, while the vent 42 inside the piston 41 closes. At this time, the negative pressure environment in the cavity below the piston 41 allows external cold air to enter from the air inlet 52 and enter the cavity below the piston 41 after passing through the airflow channel 57. During this process, the flowing air can carry away some heat through the inner cylinder 56, further reducing the temperature inside the inner cylinder 56. In addition, the back pressure of the first one-way valve 43 can also further play a damping role, so that the piston 41 rebounds stably and slowly, achieving the purpose of further shock absorption.

[0040] As an optional solution, a dustproof net 53 is provided at the air inlet 52. A baffle 54 of matching size is hinged to the air inlet 52 within the dustproof net 53. The inner side of the baffle 54 is connected to the outer side of the inner cylinder 56 via a return spring 55. The dustproof net 53 prevents dust from being brought in by the airflow and affecting the operation of the control processing module 7. The return spring 55 and the baffle 54 prevent rainwater from entering without affecting the airflow, further ensuring the normal operation of the control processing module 7.

[0041] As an optional solution, multiple vertically arranged guide cylinders 62 are evenly distributed above the heat-conducting baffle 6, and a guide post 64 extending into the upper part of the guide cylinder 62 is correspondingly provided at the lower end of the piston 41; an air bladder 63 is provided below the guide post 64, which contacts the heat-conducting baffle 6, and the air bladder 63 is filled with a volatile liquid medium with a boiling point of 35-55℃. The air bladder 63 serves two purposes: firstly, it can further reduce vibration when the piston 41 moves downward due to vehicle vibration by compressing the air bladder 63; secondly, the volatile liquid medium, with a boiling point of 35-55℃, vaporizes when the temperature inside the inner cylinder 56 reaches this range, causing the air bladder 63 to expand further, thus generating a greater counterforce and further improving the vibration reduction effect. Simultaneously, the vaporization of the liquid medium absorbs a large amount of heat, achieving a better cooling effect and preventing the internal temperature of the inner cylinder 56 from becoming too high, thus reducing the reliability of the control processing module 7.

[0042] As an alternative, the volatile liquid medium is diethyl ether or dichloromethane.

[0043] As an optional solution, a cooling fan 59 is provided at the exhaust port 58, and a magnetic switch 45 for controlling the opening and closing of the cooling fan 59 is provided on the upper outer side of the protective cylinder 5; an induction plate 44 is provided inside the piston 41 near the magnetic switch 45, and the induction plate 44 is initially positioned below the magnetic switch 45. Through the arrangement of the magnetic switch and the magnetic induction plate 44, when the temperature inside the inner cylinder 56 is too high, the volatile liquid medium in the air bladder 63 vaporizes and expands, thereby expanding the air bladder 63 and pushing the piston 41 upwards, causing its equilibrium position to move upwards. This causes the induction plate 44 to move upwards, allowing the magnetic switch to sense the induction plate 44 and send a signal to control the cooling fan to start, achieving active cooling and further improving the cooling effect. In addition, when the cooling fan starts, the gas inside the protective cylinder 5 moves from bottom to top, allowing the lighter hot air to be quickly discharged, and the unidirectional flow of the gas also prevents the discharged hot air from being re-inhaled, thus avoiding affecting the cooling effect.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
