Description

Technical Field

[0001] This utility model belongs to the field of bus manufacturing technology, and in particular relates to a magnetic adsorption and fixing device for a bus rearview mirror fixing plate. Background Technology

[0002] The current installation process for the rearview mirror on the front windshield pillar of a bus adopts an exposed fixing plate design. The specific implementation method is as follows: a special notch is opened on the pressure plate skin to expose the fixing plate. The fixing plate is welded to the edge of the notch skin using a full welding process. After electrophoresis treatment, the welded parts are puttyed and repaired. During final assembly, the base with rubber sleeve is installed first, and then the rearview mirror assembly is assembled.

[0003] While the existing solutions effectively avoid the problem of putty coating cracking caused by misalignment between the skin and the fixing plate, and ensure the reliability of the structural connection, they still have the following technical defects:

[0004] (1) Regarding the difficulties in process control: the putty application requires high precision, the operation is difficult, and the amount of putty applied is not easy to control precisely. Too much or too little will produce adverse effects. Excessive application will cause putty to accumulate at the bottom of the mirror base, while insufficient application will cause unevenness in the exposed part of the rubber sleeve.

[0005] (2) Regarding quality risks: During the installation and operation of the rearview mirror, the accumulated putty layer is prone to cracking and unevenness due to stress, which affects the appearance quality and requires touch-up painting later.

[0006] (3) In terms of production impact: rework and repair increase the workload, prolong the production cycle, affect the delivery schedule, increase production costs, and reduce economic benefits.

[0007] (4) In terms of long-term reliability: there may be color difference problems in the repaired area, and repeated repairs will affect the overall performance of the coating.

[0008] The applicant believes that while ensuring structural strength, the above-mentioned process still has room for improvement in terms of surface treatment process control, and needs to be optimized and improved to increase production efficiency and product quality. Utility Model Content

[0009] To overcome the shortcomings of the prior art, this utility model provides a magnetic adsorption fixing template device for the rearview mirror fixing plate of a bus. On the one hand, the size of the fixing template is between the rearview mirror base and the rubber sleeve, so that no putty is applied to the bottom of the fixing template. This avoids the problem of paint cracking (putty) and needing to be repaired due to the putty coating being stressed at the bottom of the mirror base, and ensures the accuracy of putty application at the rearview mirror fixing plate. On the other hand, the fixing template device is also equipped with a magnetic adsorption structure, which uses a magnetic ring to adhere flush with the rearview mirror fixing plate, and further fixes the magnetic ring to the fixing template with a cross-slot screw.

[0010] This utility model is achieved through the following technical solution:

[0011] A magnetic adsorption fixing template device for a rearview mirror fixing plate of a passenger vehicle includes a fixing template and a magnetic adsorption structure. The size of the fixing template is between that of the rearview mirror base and the rubber sleeve. The magnetic adsorption structure has two sets, upper and lower, which are symmetrically distributed with respect to the center position of the fixing template.

[0012] The magnetic adsorption structure includes a magnetic ring, a cross-slot screw, and a round hole. The magnetic ring is positioned near the center of the fixed template. A round hole is located in the center of the magnetic ring, and the center of the round hole is at the same point as the center of the magnetic ring. The exposed surface of the magnetic ring is flush with the fixed template, and a cross-slot screw passes through the round hole.

[0013] Compared with the prior art, this utility model has at least the following advantages and beneficial effects:

[0014] 1. The size of the fixed template of this utility model is between that of the rearview mirror base and the rubber sleeve, so that the bottom of the template does not need to be scraped with putty. This avoids the problem of paint (putty) cracking and repair caused by the putty coating being stressed at the bottom of the mirror base, and ensures the accuracy of putty scraping at the fixed plate part of the rearview mirror during painting.

[0015] 2. A magnetic ring is provided on the fixed template. The exposed surface of the magnetic ring is flush with the fixed template. The magnetic energy of the magnetic ring can directly attract and adhere the fixed template to the rearview mirror fixing plate. Then, the cross-slot screw passes through the round hole from the back of the fixed template. Finally, the ring at the rear end of the cross-slot screw is attached to the magnetic ring on the back of the fixed template, further fixing the magnetic ring to the fixed template.

[0016] Advantages of the present invention in additional aspects will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention.

[0021] Where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0022] Example 1

[0023] like Figure 1 As shown, a magnetic adsorption fixing template device for a bus rearview mirror fixing plate includes a fixing template 1 and a magnetic adsorption structure 2. The size of the fixing template 1 is between that of the rearview mirror base and the rubber sleeve. The magnetic adsorption structure has two sets, upper and lower, with the same structure for both sets. The two sets of magnetic adsorption structures are symmetrically distributed with respect to the center position of the fixing template.

[0024] The magnetic adsorption structure 2 includes a magnetic ring 3, a cross-slot screw 4, and a circular hole 5. The magnetic ring 3 is positioned near the center of the fixed template 1. The circular hole 5 is located in the center of the magnetic ring 3, and the circular hole 5 is located at the same point as the center of the magnetic ring 3. The exposed surface of the magnetic ring 3 is flush with the fixed template 1. In this embodiment, the magnetic ring 3 is embedded in the fixed template 1. Both exposed surfaces of the magnetic ring 3 are flush with the fixed template 1. The magnetic ring 3 itself has a certain degree of magnetism. The cross-slot screw 4 passes through the circular hole 5.

[0025] The size of the fixed template 1 is between that of the rearview mirror base and the rubber sleeve. The outer diameter of the fixed template 1 is slightly smaller than that of the rearview mirror base but larger than that of the rubber sleeve, forming a "step-like barrier". This ensures that no putty seeps into the rubber sleeve installation area (the part covered by the template) during the scraping process, and the welding and finishing area (the part not covered by the template) is accurately filled. This achieves precise control of the putty scraping accuracy at the rearview mirror fixing plate area during painting, and prevents putty from being scraped at the bottom of the template. This avoids the problem of paint (putty) cracking and touch-up caused by the putty coating being stressed at the bottom of the mirror base.

[0026] The material selection for bus rearview mirror mounting plates takes into account factors such as strength, weather resistance, and process compatibility. Galvanized steel plates and aluminum alloys are commonly used. Specifically, to balance cost and reliability, galvanized steel plates, such as the DC51D+Z galvanized cold-rolled steel plate, are preferred for conventional models. For weight reduction and energy saving, aluminum alloys, such as the 6061-T6 aluminum alloy, can be used for new energy / high-end models. However, regardless of the material used, the bus rearview mirror mounting plate can be attracted by the magnetic ring 3.

[0027] In this embodiment, the exposed surface of the magnetic ring 3 on the side closest to the bus rearview mirror fixing plate is flush with the fixing template 1. This ensures that the magnetic energy characteristics of the magnetic ring can attract and adhere the fixing template 1 and the rearview mirror fixing plate to a flush position without any gaps between them. Furthermore, the two sets of symmetrically distributed magnetic adsorption structures 2 can further enhance the adsorption stability between the fixing template 1 and the rearview mirror fixing plate.

[0028] For structural reliability considerations, the circular hole 5 in this embodiment is threaded. Compared to a plain hole and bolt, the threaded engagement between the circular hole 5 and the Phillips head screw 4 results in a more uniform load distribution, which can improve tensile strength. The helical structure of the thread can disperse stress concentration and reduce the risk of microcrack initiation. Since both exposed surfaces of the magnetic ring 3 are flush with the fixing template 1, after the Phillips head screw 4 is screwed into the circular hole 5 with a Phillips head screwdriver, the nut part on the back of the Phillips head screw 4 can be tightly connected to the magnetic ring 3 on the side of the fixing template 1 away from the rearview mirror fixing plate. Finally, the ring 5 at the rear end of the Phillips head screw 4 will be attached to the magnetic ring 3 on the back of the fixing template 1, compressing the space between the fixing template 1 and the rearview mirror fixing plate, and also preventing the magnetic ring 3 from moving outward, further realizing the fixation between the fixing template 1 and the rearview mirror fixing plate.

[0029] In addition, the five round holes will be countersunk. In terms of assembly flatness, the head of the cross-screw 4 can be sunk into the workpiece surface to avoid interference with other parts, eliminate protrusions, and ensure a flat and bulging appearance. In terms of stress optimization, it increases the contact area between the fastener and the workpiece, reduces local pressure, and the countersunk hole structure can also suppress vibration transmission. When used with flange bolts, it can improve the anti-loosening effect by more than 2 times.

[0030] Since the magnetic ring 3 itself has a magnetic energy effect, and the cross-head screw 4 is generally made of a rigid structure, after the cross-head screw 4 is screwed into the round hole with the help of a cross-head screwdriver, the nut on the back of the cross-head screw 4 will also be affected by the magnetic energy effect of the magnetic ring 3, which will make the nut and the magnetic ring fit together more tightly.

[0031] To ensure accurate connection and positioning between the fixed template 1 and the rearview mirror fixing plate, this embodiment also provides bolt holes 6 on the fixed template 1. The bolt holes 6 are provided in two sets, upper and lower, and the two sets of bolt holes 6 are symmetrically distributed with respect to the center position of the fixed template 1. Since the two sets of bolt holes 6 are symmetrically distributed with respect to the center position of the fixed template 1, this embodiment will only use one set as an example for explanation.

[0032] The bolt holes 6 are located on the outer side of the magnet ring 3, away from the center of the fixed template 1. Taking the upper half of the fixed template as a reference, the bolt holes 6 are positioned above the magnet ring 3. Each set of bolt holes 6 includes a first bolt hole 7 and a second bolt hole 8. The first bolt hole 7 is located to the left of the second bolt hole 8. The first bolt hole 7 and the second bolt hole 8 are symmetrically distributed with respect to the magnet ring 3. Each set of bolt holes is cut on the fixed template by laser. The diameter of the bolt holes is consistent with the bolt holes of the rearview mirror mounting plate. A bolt 9 is welded into each bolt hole 6. The bolt 9 is used to insert into the bolt holes of the rearview mirror mounting plate. The bolts tightly fit the fixed template and the rearview mirror mounting plate together. In addition, the size of the fixed template is between that of the rearview mirror base and the rubber sleeve. Thus, the bolts can achieve precise front-to-back fitting of the corresponding parts of the fixed template and the rearview mirror mounting plate, which can play a role in precise template positioning.

[0033] To ensure that the rearview mirror mounting plate can be securely attached to the mounting template 1 using bolts, the end of the bolt 9 is ground into a sharp state, making it easy for the bolt 9 to be quickly inserted into the bolt hole of the rearview mirror mounting plate, and it is not easily interfered with by obstacles during the insertion process.

[0034] In addition, the upper end of the fixed template 1 in this embodiment is provided with an indicator arrow mark 10. The indicator arrow mark is pointing upwards. The indicator arrow 10 is used to indicate the correct direction of using the fixed template. A handle 11 is welded on the side of the fixed template away from the indicator arrow mark. On-site operators can use the handle 11 to hold the template and insert the bolt into the bolt hole of the rearview mirror mount fixing plate and disassemble the template.

[0035] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
