Technical Field
[0001] The utility model relates to the debugging and fixing of vehicle-mounted accessories, in particular to a vehicle-mounted sensor quick-disassembly structure. Background Art
[0002] With the development of networking technology, the types of sensors in current vehicles are gradually increasing. Before designing and producing vehicles, it is necessary to conduct relevant tests on the sensor positions based on the vehicle model to determine the specific position of the sensor and the degree of adaptation of the sensor type to the vehicle shape. Therefore, there are currently multiple installation points on the vehicle assembly used for vehicle testing. Sensors are installed through the installation points and the working status of the sensors is tested. On the one hand, the test requires replacing multiple types of sensors to obtain the working data of the corresponding sensors. On the other hand, the installation stability of the sensors needs to be adjusted to simulate the fluctuations that may have specific requirements for the position accuracy of the sensors in specific scenarios or projects.
[0003] During the simulation test, on one hand, a quick release is used as a locking part, and the plug of the quick release is inserted into the base of the sensor for installation, and the insertion depth of the plug is used to simulate the influencing factors. On the other hand, the bolt is directly inserted into the base of the sensor and tightened to simulate the influencing factors of assembly jitter.
[0004] The currently used quick release mainly applies thrust to the whistle through a spring structure. The whistle is directly inserted into the bottom of the sensor base under the action of the spring. If the insertion depth needs to be adjusted, a pin is often used for position limiting, and the adjustment method is inefficient. Therefore, it is worth studying how to optimize the existing quick release and better control the fixing method of the whistle. Utility Model Content

DETAILED DESCRIPTION
[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0029] Traditional quick release devices mainly use a carrier as the support structure of the entire quick release structure, and use a plug that slides inside the carrier to limit the position. Usually, a spring or other component is used as a reset mechanism. The plug is connected through the reset mechanism, so that the reset mechanism applies a thrust to the plug, causing it to slide along the inner cavity of the carrier, and then extend out of the carrier and insert into the sensor base. However, this structure makes the plug's activity stroke larger, and the insertion depth of the plug cannot be well adjusted when the plug is inserted into the sensor base. In particular, when the locking degree of the sensor is used as a factor to conduct a factor experiment, it is often necessary to replace quick release devices of different depths. Although there are many types of mainstream quick release devices at present, can they meet the needs? However, this frequent replacement is obviously inconvenient for the experimental process. In addition, due to equipment management problems, some quick release devices with specific insertion depths are often lost, which may cause the experiment to be temporarily postponed.
[0030] Based on this, reference Figure 1 and Figure 2As shown, one embodiment of the utility model is a vehicle-mounted sensor quick-release structure, comprising a carrier 1, a whistle 2 and a reset mechanism 3; wherein the carrier 1 and the whistle 2 can be existing quick-release carriers, and the reset mechanism 3 can be an existing reset spring. The above-mentioned carrier 1 is installed on a vehicle assembly. The above-mentioned carrier 1 is hollow, wherein the hollowness of the carrier 1 is mainly convenient for milling processing based on the existing carrier 1, so that the carrier 1 can obtain the required inner cavity profile and size. The above-mentioned whistle 2 is slidably arranged in the inner cavity of the carrier 1; wherein the maximum cross-sectional profile of the whistle 2 is adapted to the inner cavity profile of the carrier 1, so that the whistle 2 can slide in the inner cavity of the carrier 1. Among them, the above-mentioned reset mechanism 3 is fixed in the inner cavity of the carrier 1, and the above-mentioned reset mechanism 3 resists the whistle 2, and the reset mechanism 3 applies a thrust to the whistle 2; so that the front end of the whistle 2 is used to extend out of the carrier 1 and be inserted into the sensor base. The reset mechanism 3 continuously applies a thrust to the whistle 2 to ensure that the whistle 2 maintains a tendency to move toward the carrier 1, and also facilitates the whistle 2 on the carrier 1 to be quickly inserted after being placed in the corresponding position of the sensor base.
[0031] In order to limit the insertion depth of the whistle 2, the carrier 1 is provided with a reference sleeve 4 in the inner cavity, wherein the reference sleeve 4 is hollow, and a slider 501 is slidably arranged in the reference sleeve 4, and the slider 501 slides in the inner cavity of the reference sleeve 4, and a support rod 502 is arranged at the end of the slider 501, and the end of the support rod 502 is connected to the whistle 2, and the slider 501 moves in the inner cavity of the reference sleeve 4 and drives the support rod 502, and the support rod 502 is used to apply a pulling force or a pushing force to the whistle 2. That is, when the slider 501 moves forward in the direction of the whistle 2, the support rod 502 pushes the whistle 2, and vice versa, if the slider 501 moves backward, the support rod 502 pulls the whistle 2.
[0032] In order to better control the position of the slider 501 in the reference sleeve 4, an adjusting bolt 503 is provided on the reference sleeve 4, wherein the reference sleeve 4 and the adjusting bolt 503 are matched with bolts, and the adjusting bolt 503 is rotated on the reference sleeve 4, so that the depth of the adjusting bolt 503 inserted into the reference sleeve 4 changes, and the slider 501 is connected by the adjusting bolt 503, so that the slider 501 can be displaced as the adjusting bolt 503 rotates on the reference sleeve 4. At the same time, considering that the slider 501 rotates synchronously with the adjusting bolt, there may be a risk of load transmission, therefore, the end of the adjusting bolt 503 extends into the inner cavity of the reference sleeve 4 and is connected to the slider 501 through the bearing 504, wherein the outer ring of the bearing 504 is connected to the slider 501, and the movable end of the bearing 504 is connected to the adjusting bolt 503, and the adjusting bolt 503 rotates to apply a push-pull force to the slider 501, thereby avoiding the risk of the slider 501 rotating, so that the adjusting bolt 503 can pull the slider 501 when rotating on the reference sleeve 4.
[0033] refer to Figure 3As shown, based on the above embodiment, another embodiment of the utility model is that in order to better meet the adaptive functional requirements of the whistle 2 after the slider 501 limits the whistle 2, the slider 501 is provided with an adjustment cavity 505, the head end of the strut 502 is slidably arranged in the adjustment cavity 505, and the head end of the strut 502 is provided with a limit plate 506, and the limit plate 506 is used to limit the movement of the strut 502 in the adjustment cavity 505; that is, the limit plate is installed at the head end of the strut, and when the strut moves in the adjustment cavity 505, the limit plate 506 is used to prevent the strut 502 from accidentally falling out of the adjustment cavity 505, which is conducive to the adjustment cavity 505 applying a pulling force or a pushing force to the limit plate 506. Through the adjustment cavity 505 on the slider 501, the strut 502 has a certain activity space on the basis of moving with the slider 501, and the depth of the adjustment cavity 505 represents the length of the adaptive movement of the strut 502 and the whistle 2.
[0034] The adaptive movement refers to the travel of the whistle 2 under the influence of the reaction force of the reset mechanism 3 and the sensor base.
[0035] It should be noted that, although the design of the adjustment cavity 505 allows the whistle 2 to move adaptively, the position of the adjustment cavity 505 is still limited by the position of the slider 501, and thus the moving area of the whistle 2 is also controllable.
[0036] Based on the above embodiments, reference Figure 3 and Figure 4 As shown, another embodiment of the present invention is that in order to better constrain the travel of the adjusting bolt 503 and the slider 501, the reference sleeve 4 includes a mounting plate 401 and a sleeve 402, and the mounting plate 401 and the sleeve 402 are T-shaped.
[0037] The mounting plate 401 is mounted on one end of the sleeve 402, and the sleeve 402 extends into the inner cavity of the carrier 1. The carrier 1 is provided with a mounting groove that fits the mounting plate 401; wherein the mounting plate 401 is fixed on the carrier 1 as a reference surface, and the inner contour of the mounting groove is adapted to the outer contour of the mounting plate 401, thereby ensuring the stability of the mounting plate 401 during installation, so that the central axis of the sleeve 402 partially overlaps with the central axis of the carrier 1. The mounting plate 401 is provided with a screw hole for the adjustment bolt 503 to pass through, and the mounting plate 401 is threadedly matched with the adjustment bolt 503. The mounting plate 401 has a certain thickness, and on the basis of threaded matching, it is beneficial for the adjustment bolt 503 to maintain a parallel posture with the sleeve 402 during the insertion process of the sleeve 402.
[0038] Furthermore, considering the influence of the distance of the adjustment cavity 505 on the whistle 2, in order to better control the whistle 2, an operating gap 601 is provided between the outer wall of the sleeve 402 and the inner wall of the carrier 1, and the operating gap 601 is provided with a pull rod 602, the front end of the pull rod 602 is connected to the whistle 2, and the rear end of the pull rod 602 extends to the outside of the carrier 1 through the mounting plate 401.
[0039] The pull rod 602 is mainly used to directly apply pulling force to the whistle 2, and then directly interfere with the movement of the whistle 2 within the movable range of the whistle 2 and the support rod 502. It should be noted that when the pull rod 602 pulls the whistle 2 to move, if the limit plate 506 on the support rod 502 simultaneously resists the adjustment cavity 505, the pull rod 602 cannot continue to be pulled, thereby limiting the excessive influence of the pull rod 602 on the whistle 2 to a certain extent.
[0040] Furthermore, in order to facilitate the pull rod 602 to uniformly apply tension to the whistle 2, there are more than two pull rods 602, and the pull rods 602 surround the sleeve 402. A collar 603 is provided on one side of the carrier 1, wherein the collar 603 is used to connect multiple pull rods 602, that is, all pull rods 602 can be directly and synchronously force applied through the collar 603. The collar 603 is connected to the head end of the pull rod 602, and a through hole is provided in the middle of the collar 603, and the through hole corresponds to the adjustment bolt 503. The through hole on the collar 603 is mainly used to prevent the collar 603 from affecting the adjustment of the adjustment bolt 503.
[0041] Based on the above embodiment, another embodiment of the utility model is that, in order to better avoid the mutual contact between the adjusting bolt 503 and the reset mechanism, the inner cavity of the carrier 1 includes a first cavity 101 and a second cavity 102, the first cavity 101 and the second cavity 102 are connected to each other, the reference sleeve 4 is located in the first cavity 101, and the reset mechanism 3 is located in the second cavity 102. The spatial portion of the first cavity 101 and the second cavity 102 helps to reduce the mutual interference between the adjusting bolt 503 and the reset mechanism, ensure the functional independence and stability of each, facilitate maintenance and installation, and thus ensure the reliability and durability of the entire quick-release structure.
[0042] Exemplarily, the whistle plug 2 includes a plug portion 201 and a guide portion 202, and the cross section of the guide portion 202 matches the cross section of the second cavity 102; by matching the cross section of the guide portion 202 with that of the second cavity, it can be ensured that the whistle plug is stably fitted to the second cavity 102 during the sliding process, and the guide portion 202 is prevented from shaking randomly in the second cavity 102. The plug portion 201 is connected to the guide portion 202, and the design of the plug portion allows the whistle plug to be easily extended from the end of the carrier and accurately inserted into the sensor base. When the guide portion 202 is subjected to force, the guide portion 202 drives the plug portion 201 to extend from the reserved hole at the end of the carrier 1 and insert into the sensor base.
[0043] Furthermore, a step is provided at the junction of the second cavity 102 and the first cavity 101, and the reset mechanism 3 includes a guide post 301 and a spring 302. The guide post 301 is provided on the step, and the guide portion 202 is sleeved on the guide post 301, and the guide post 301 constrains the posture of the guide portion 202 in the second cavity 102; during the sliding process of the plug whistle 2, the guide post 301 acts as a physical limiting element to enhance the stability of the movement of the guide portion 202. The spring 302 is sleeved on the guide post 301, and the two ends of the spring 302 respectively contact the step and the guide portion 202, which is conducive to the spring 302 applying the tension of the spring to the guide portion 202. The guide post 301 is used to limit the guide portion 202 of the plug whistle 2, thereby ensuring that the plug portion 201 of the plug whistle 2 maintains a corresponding posture.
[0044] Furthermore, the guide posts 301 are more than two, which helps maintain the high performance of the system and reduce the risk of equipment failure caused by unexpected failures. The guide posts 301 are distributed in the second cavity 102 around the central axis of the reference sleeve 4. The guide posts 301 are multiple, which facilitates the stable transfer of loads and increases the guiding effect of the guide posts 301 on the whistle 2. Reduce the risk of imbalance of the whistle 2 under the action of the reset mechanism.
[0045] Based on the above embodiments, reference Figure 1 As shown, another embodiment of the utility model is that the front end of the carrier 1 is provided with a support ear, and the support ear is provided with a screw hole, and the support ear is used to install the carrier 1 on the vehicle assembly.
[0046] Based on the above embodiments, reference Figure 2 and Figure 3 As shown, another embodiment of the utility model is that in order to ensure that the support rod 502 can stably apply thrust or pull to the sentry 2, the support rod 502 is multiple, and the gap between two adjacent support rods 502 is the same. The number of support rods 502 is convenient for load transfer to the sentry 2, thereby ensuring that the thrust of the support rod 502 can stably act on the sentry 2.
[0047] Based on the above embodiments, this embodiment is a working embodiment. For ease of understanding, the working state of the structure is described here:
[0048] When you need to reduce the extension distance of the whistle 2, refer to Figure 5 As shown, by adjusting the bolt 503 to cooperate with the movement of the slider 501, the adjusting bolt 503 is rotated to make the slider 501 move backward, and when the slider 501 moves backward, the limiting plate 506 contacts the adjustment cavity 505. At this time, under the contact of the limiting plate 506, the support rod 502 is pulled by the slider 501, driving the whistle 2 to move backward synchronously. At this time, if the position of the slider 501 is limited by the adjusting bolt 503, the whistle 2 is constrained by the support rod 502, and the backward position of the whistle 2 is the maximum extension position of the whistle 2.
[0049] When it is necessary to limit the pressure on the whistle 2 after insertion, refer to Figure 6 As shown, the slider 501 is driven to move toward the whistle plug 2 by adjusting the bolt 503. When the slider 501 moves forward and causes the limit plate 506 to contact the adjustment cavity 505, the slider 501 pushes the whistle plug 2 forward. At this time, the whistle plug 2 is in the maximum retracted position.
[0050] It should be noted that if the slider 501 continues to push the whistle 2, the whistle 2 can be made to fit the inner wall of the carrier 1, so that the inner wall of the carrier 1 cooperates with the slider 501 to clamp the whistle 2, so that the reset mechanism will not have any effect on the whistle 2. If necessary, this method can meet experimental requirements.
