Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle sensor fixing structure technical field especially relates to a fixing card structure for vehicle sensor, lower cover structure and vehicle sensor. BACKGROUND

[0002] The common vehicle sensor is usually composed of an upper cover, a lower cover and a metal buckle in the structural design. The upper cover and the lower cover jointly constitute the shell of the sensor, which protects the internal precision electronic components from the interference of dust, water vapor and vibration from the outside world. The metal buckle is mainly used to realize the fixed installation of the sensor and the vehicle body or other components, and to ensure the stability of the sensor during the driving of the vehicle.

[0003] At present, the installation of this kind of vehicle sensor in the industry generally adopts a step-by-step assembly process, and the specific process is as follows:

[0004] Firstly, the lower cover and the upper cover are assembled. The operator precisely connects the lower cover and the upper cover by buckle cooperation, screw fixation or glue bonding, etc. and forms a complete shell structure to complete the preliminary packaging of the internal components.

[0005] Secondly, after the assembly of the upper cover and the lower cover, the metal buckle is installed on the lower cover by hot riveting process. That is, the pre-riveting column of the lower cover is softened by high temperature heating, and then the softened riveting column is deformed and tightly combined with the metal buckle by applying pressure with the help of the mold, so as to realize the fixation of the metal buckle.

[0006] However, this traditional installation process has many defects that are difficult to avoid:

[0007] Firstly, the application of hot riveting process leads to high product rejection rate. The hot riveting process has high requirements for temperature control, pressure parameters and operation timing: if the heating temperature is too high, the lower cover (usually made of plastic material) will be damaged irreversibly, such as burning, cracking, etc. If the temperature is too low or the pressure is insufficient, the effective riveting strength cannot be formed, and the metal buckle is easy to loosen and fall off. If the hot riveting position deviates, it will also cause the metal buckle to be installed obliquely, affecting the subsequent vehicle assembly of the sensor. Since the parameter window of the hot riveting process is narrow, and is greatly affected by the skill level of the operator, the stability of the equipment, etc., the proportion of product rejection due to unqualified hot riveting is usually high in actual production, which greatly increases the production cost.

[0008] Secondly, during transportation, the metal buckle is prone to falling due to improper assembly. If there are hidden defects (such as the riveting column not completely filling the buckle mounting hole, local non-fusion, etc.) in the connection structure formed by the hot riveting process, the connection strength of the metal buckle and the lower cover will be further weakened when the sensor product is transported or stored, subjected to external forces such as jolting and vibration, and finally the metal buckle will fall off from the lower cover. The falling of the metal buckle not only makes the sensor lose the installation foundation and cannot be normally assembled to the vehicle, but also may cause secondary damage (such as jamming of mechanical structures, scratching of electronic components, etc.) due to the mixing of the buckle with other components, increasing the difficulty of quality control.

[0009] Thirdly, the assembly steps are too cumbersome, which seriously restricts the production efficiency of the product. The traditional process needs to complete the assembly of the upper cover and the lower cover first, and then separately perform hot riveting of the metal buckle. Auxiliary operations such as workpiece transfer and positioning calibration are needed between the two processes, which prolongs the production cycle of a single product. In the automatic production line, this step-by-step operation mode increases the equipment investment (such as additional hot riveting workstations and transfer mechanisms) and process connection time, reduces the overall pace of the production line, and is difficult to meet the efficiency requirements of large-scale production.

[0010] In addition, when assembling the metal buckle, it is easy to cause rework due to the quality problem of the lower cover. Since the hot riveting process of the metal buckle is arranged after the assembly of the upper cover and the lower cover, when the lower cover has potential defects (such as size deviation, position deviation, material impurities, etc.), they are often discovered during the hot riveting process. At this time, the upper cover and the lower cover have been assembled. If the lower cover needs to be replaced, the assembled shell structure needs to be disassembled first, which not only increases the rework cost, but also may damage the upper cover or internal components during disassembly, further reducing the production yield. At the same time, this "late discovery" of quality problems also makes it impossible to effectively screen the quality of the lower cover in advance, affecting the stability of the production process.

[0011] The problems of needing hot riveting process, low product yield, low production efficiency, improper assembly, and inability to check the quality of the lower cover in advance in the related art have not been effectively solved. Content of the utility model

[0012] The utility model aims at the deficiencies in the prior art, and provides a fixing card structure for a vehicle-mounted sensor, a lower cover structure and a vehicle-mounted sensor, to solve the problems of needing hot riveting process, low product yield, low production efficiency, improper assembly and inability to check the quality of the lower cover in advance in the related art.

[0134] In some embodiments, the spacing members 223 include, but are not limited to, gaps.

[0135] Further, the second plug-in element 220 further comprises a plurality of inclined members 224. The plurality of inclined members 224 are respectively arranged at the top ends of the corresponding limiting members 222, for guiding the first plug-in element 120 to move downwardly when the first plug-in element 120 abuts against the plurality of inclined members 224.

[0136] The inclined members 224 are formed at the top ends of the limiting members 222.

[0137] The number of the inclined members 224 matches the number of the limiting members 222. Generally, the number of the inclined members 224 is equal to the number of the limiting members 222.

[0138] The inclined direction of the inclined members 224 is inclined from inside to outside and from top to bottom. Herein, “inside” refers to the direction of a plug-in member 221 close to the center formed by the plurality of plug-in members 221, “outside” refers to the direction of a plug-in member 221 away from the center formed by the plurality of plug-in members 221, “top” refers to the direction of the top end of the limiting member 222, and “bottom” refers to the direction of the bottom end of the limiting member 222.

[0139] In some embodiments, the inclined members 224 include, but are not limited to, inclined surfaces, such as inclined planes and inclined arc surfaces.

[0140] In some embodiments, the second limiting elements 230 are two. The two second limiting elements 230 are symmetrically arranged at the two sides of the lower cover element 210, or the two second limiting elements 230 are asymmetrically arranged at the two sides of the lower cover element 210.

[0141] In some embodiments, the second limiting elements 230 are four. The four second limiting elements 230 are symmetrically arranged at the two sides of the lower cover element 210. Among them, two second limiting elements 230 are arranged close to the third side of the lower cover element 210, and two second limiting elements 230 are arranged close to the fourth side of the lower cover element 210.

[0142] The number of the second limiting elements 230 matches the number of the first limiting elements 130. Generally, the number of the second limiting elements 230 is equal to the number of the first limiting elements 130.

[0143] Generally, the second limiting elements 230 are transversely limited and connected (abut, clamped) with the first limiting elements 130.

[0144] In some embodiments, the second limiting elements 230 include, but are not limited to, limiting grooves.

[0145] Further, the lower cover structure 200 further comprises two third limiting elements 240. Wherein, the two third limiting elements 240 are symmetrically arranged on the first side and the second side of the lower cover element 210, and used for abutting against the first side and the second side of the fixed card structure 100.

[0146] Specifically, the third limiting element 240 abuts against the first side and the second side of the card main body element 110.

[0147] The third limiting element 240 is formed on the top end of the lower cover element 210. Generally, the third limiting element 240 is integrally formed with the lower cover element 210.

[0148] The size of the third limiting element 240 matches the size of the card main body element 110. Generally, the length of the third limiting element 240 is not less than the length of the card main body element 110.

[0149] In some embodiments, the third limiting element 240 includes but is not limited to a limiting plate.

[0150] The technical effects of the embodiment are as follows:

[0151] 1) The lower cover structure is connected with the first inserting element of the fixed card structure through the second inserting element, without the hot riveting process, greatly improving the product yield and reducing the scrap rate.

[0152] 2) The lower cover structure is limited by the first limiting element of the fixed card structure through the second limiting element, preventing the up and down shaking and reducing the assembly deviation.

[0161] Moving the fixed card body element 110 downwards, in the moving process, the first plug-in element 120 abuts against the inclined pieces 224 of the corresponding second plug-in element 220, under the action of force, the top end of the plug-in pieces 221 moves inward, thereby driving the limiting pieces 222 to move;

[0162] With the continuous movement, the outer edge surface of the limiting pieces 222 abuts against the inner edge surface of the first plug-in element 120;

[0163] Continuing to move, the inner edge surface of the first plug-in element 120 abuts against the outer edge surface of the plug-in pieces 221, with the force applied to the inclined pieces 224 being removed, the plug-in pieces 221 reset, and the limiting pieces 222 abut against the card body element 110;

[0164] At the same time, the first limiting elements 130 are clamped in the corresponding second limiting elements 230;
