Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of guiding assembly, and particularly relates to an auxiliary guiding assembly tool. BACKGROUND

[0002] The illuminating lamp of the automobile trunk can be automatically turned off and turned on with the opening and closing of the trunk door, but when the trunk is filled with various items, the illumination is still dim, and it is difficult to find the required items, so many cars also install illuminating lamps on the tail door of the trunk to increase the light source in the trunk. The trunk lamp is located directly above the user's head or slightly behind the user's head, and the illuminating area on the trunk is not blocked by the user's head when the user takes things.

[0003] As shown in Figure 1 The existing automobile trunk tail door is mostly formed by splicing an inner plate 1 and an outer plate 2, and the inner plate 1 is provided with a lamp mounting hole so that the lampshade of the illuminating lamp 3 can extend out of the inner plate 1 to illuminate the trunk. The inner plate 1 includes a first environmental part 11 and a second environmental part 12, and the first environmental part 11 and the second environmental part 12 are provided with coaxial through holes. In order to ensure the overall strength of the tail door, the existing automobile tail door is mostly formed by metal pieces to replace plastic injection pieces. However, during the metal piece forming process, the first environmental part 11 and the second environmental part 12 will have certain manufacturing tolerances, resulting in a large deviation in the coaxiality between the through holes of the first environmental part 11 and the second environmental part 12 after fitting and installation. In addition, the diameter of the through hole of the first environmental part 11 is only slightly larger than the outer diameter of the lampshade (a large size difference will result in a large gap affecting the aesthetic effect), and the lamp mounting hole on the inner plate 1 cannot be seen by the operator for assembly due to the shielding of the outer plate 2, so that the lampshade of the illuminating lamp 3 is easily collided or rubbed with the first environmental part 11 during assembly, affecting the installation efficiency and also damaging the outer surface of the lampshade. SUMMARY

[0004] The purpose of the present application is to solve the above-mentioned problems existing in the prior art, and to provide an auxiliary guiding assembly tool for improving the assembly efficiency.

[0010] In the auxiliary guiding assembly tool, the guiding shell is fixedly provided with an air bag support, the air bag support is provided with a communication hole, and the working air bag and the suction disc are respectively fixed at two ends of the air bag support and communicated with the communication hole.

[0011] In the auxiliary guiding assembly tool, the guiding shell comprises a guiding base and a guiding support, the guiding base and the guiding support are screw-fixed, and the air bag support is provided with a fixing ring; after the guiding base and the guiding support are screw-fixed to each other, the guiding base and the guiding support clamp and fix the fixing ring.

[0012] In the auxiliary guiding assembly tool, one end of the guiding shell away from the suction disc is fixedly provided with a guiding protection part, and the guiding protection part is shaped to be adapted to the shape of the contact part of the exposed surface of the product.

[0013] In the auxiliary guiding assembly tool, when the negative pressure generator is in a normal state, one end of the suction disc away from the negative pressure generator extends out of the guiding shell; when the negative pressure generator is in a negative pressure state, after the suction disc is adsorbed and fixed to the exposed surface of the product, the end face of one end of the suction disc away from the negative pressure generator is flush with the end face of the end of the guiding shell close to the suction disc.

[0014] In the auxiliary guiding assembly tool, one end of the working air bag away from the suction disc is provided with a reinforcing pad.

[0015] Compared with the prior art, the present application has the following advantages:

DETAILED DESCRIPTION

[0025] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0027] As shown in Figures 2-5 An auxiliary guide assembly tool, comprising a guide shell 100, the guide shell 100 is provided with a suction disc 101 which can contact the exposed surface of the product, and a negative pressure generator is also provided in the guide shell 100 and is in communication with the suction disc, the outer size of the guide shell 100 gradually decreases along the direction of the suction disc 101 towards the negative pressure generator, and when the negative pressure generator generates negative pressure, the suction disc 101 can be adsorbed and fixed with the exposed surface of the product.

[0028] Specifically, the end of the guide shell 100 facing the exposed surface of the product is provided with an opening, and the suction disc 101 penetrates into the guide shell 100 through the opening and is in communication with the negative pressure generator.

[0029] In this embodiment, when it is necessary to assemble and fix the lighting lamp 3 with the inner plate 1, the suction disc 101 is adsorbed and fixed with the exposed surface of the product by using the negative pressure generator to generate negative pressure, and the guide shell 100 is fixed on the lampshade to increase the guide length of the lampshade, so as to facilitate the exposed surface of the lampshade to penetrate through the lamp mounting hole and increase the assembly efficiency between the lighting lamp 3 and the inner plate 1; and the suction disc 101 is made of flexible material, so that the suction disc 101 will not cause damage to the exposed surface of the lampshade when the suction disc 101 is adsorbed and fixed with the exposed surface of the lampshade.

[0030] It is worth mentioning that the outer size of the guide shell 100 gradually decreases along the direction of the suction disc 101 towards the negative pressure generator, so that the end of the guide shell 100 away from the suction disc 101 still has a large gap with the lamp mounting hole when it penetrates through the lamp mounting hole, facilitating the guide shell 100 to penetrate into the lamp mounting hole.

[0031] Of course, this application is not limited to the installation of lighting fixtures, but can also be applied to other short guide products.

[0032] More preferably, the negative pressure generator includes a working airbag 102 disposed inside the guide shell 100, one end of the working airbag 102 being connected to the suction cup 101, and the other end of the working airbag 102 extending out of the guide shell 100; the working airbag 102 is made of an elastic self-resetting material.

[0033] In this embodiment, the working airbag 102 is made of elastic self-resetting material. When the working airbag 102 is squeezed by external force, it will release the internal air. At this time, the suction cup 101 is brought into contact with the exposed surface of the lamp cover. Due to its self-resetting characteristics, the working airbag 102 generates negative pressure, which adsorbs and fixes the suction cup 101 to the exposed surface of the product. After the lighting lamp 3 is assembled, the suction cup 101 can be pulled off the lamp cover. The operation is simple and convenient.

[0034] Further preferably, it also includes a protective cover 103 that can slide relative to the guide shell 100. The protruding end of the working airbag 102 is located inside the protective cover 103. One end of the protective cover 103 extends into the guide shell 100, and a limit hook 104 is provided at the extended end of the protective cover 103. A limit ring 105 is provided at the end of the guide shell 100 away from the suction cup 101. When the protective cover 103 wants to detach from the guide shell 100, the limit hook 104 abuts against the limit ring 105.

[0035] In this embodiment, when the end of the working airbag 102 is exposed outside the guide shell 100 and comes into direct contact with the hands of the assembly personnel, the sweat, dust or other impurities on the hands of the assembly personnel will cause corrosion and aging of the working airbag 102 and affect its service life. Therefore, a protective cover 103 is provided at the end of the working airbag 102 to surround and protect the working airbag 102, and to isolate the working airbag 102 from direct contact with the hands, so as to increase the service life of the working airbag 102.

[0036] More preferably, a return spring 106 is also provided inside the guide shell 100. One end of the return spring 106 extends into the guide shell 100 and abuts against the guide shell 100, and the other end of the return spring 106 extends into the protective cover 103 and abuts against the protective cover 103.

[0037] It is worth mentioning that an abutment ring 107 is fixedly installed inside the guide shell 100. One end of the return spring 106 abuts against the abutment ring 107. An installation ring 108 is provided inside the protective cover 103. The installation ring 108 and the inner sidewall of the protective cover 103 form an installation cavity with one end open. The other end of the return spring 106 extends into the installation cavity and abuts against the protective cover 103. This ensures that when the protective cover 103 is pressed to squeeze the working airbag 102, the return spring 106 will not deviate during compression or release, so as to prevent the return spring 106 from contacting the working airbag 102 and causing scratches on the outer surface of the working airbag 102, thus affecting the service life of the working airbag 102.

[0038] In this embodiment, the reset spring 106 ensures that the protective cover 103 quickly returns to its initial position, preparing for the next press of the working airbag 102.

[0039] More preferably, the protective cover 103 is provided with an vent hole 109 along the length of the protective cover 103.

[0040] In this embodiment, pressing the protective cover 103 to compress the working airbag 102 to generate negative pressure is a relatively rapid action. During the pressing of the protective cover 103, the air inside the protective cover 103 and the guide shell 100 cannot flow out from the gap between the protective cover 103 and the guide shell 100 very quickly. The air inside the guide shell 100 will create resistance to the pressing of the protective cover 103, affecting the assembly efficiency. Therefore, an overflow hole 109 is provided on the protective cover 103 to speed up the air discharge.

[0041] Specifically, the protective cover 103 includes a sliding cover 110 with openings at both ends. A pressing cover 111 is fixedly installed at one end of the sliding cover 110. The working airbag 102 extends into the sliding cover 110 through the other end opening and abuts against the pressing cover 111. An overflow hole 109 is provided on the sliding cover 110 and is parallel to the length direction of the sliding cover 110, so that when the protective cover 103 is pressed and extends into the guide shell 100 to reach the maximum working stroke, a portion of the overflow hole 109 is still exposed outside the guide shell 100.

[0042] More preferably, an airbag bracket 112 is fixedly installed inside the guide shell 100. The airbag bracket 112 is provided with a connecting hole. The working airbag 102 and the suction cup 101 are respectively fixed at both ends of the airbag bracket 112 and connected to the connecting hole.

[0043] In this embodiment, an airbag support 112 with a communicating hole is provided inside the guide shell 100. The working airbag 102 and the suction cup 101 are respectively fixed at both ends of the airbag support 112 to fix the positions of the working airbag 102 and the suction cup 101 in the guide shell 100, and at the same time make the working airbag 102 and the suction cup 101 communicate.

[0044] More preferably, the guide shell 100 includes a guide base 113 and a guide bracket 114, the guide base 113 and the guide bracket 114 are screwed together and fixed, and a fixing ring 118 is provided on the airbag bracket 112. When the guide base 113 and the guide bracket 114 are screwed together and fixed, the guide base 113 and the guide bracket 114 clamp and fix the fixing ring 118.

[0045] It is worth mentioning that a fixed step 115 is provided inside the guide bracket 114. The airbag bracket 112 is placed on the fixed step 115. After the guide base 113 is screwed and fixed to the guide bracket 114, the guide base 113 and the fixed step 115 cooperate to clamp and fix the fixing ring 118, thereby fixing the position of the airbag bracket 112 inside the guide shell 100.

[0046] It is worth mentioning that, in other embodiments, the guide bracket 114 and the guide base 113 can be integrally injection molded, and a buckle can be provided in the guide bracket 114 to fasten and fix it to the working airbag 102.

[0047] More preferably, a guide protection part 116 is fixedly provided at one end of the guide shell 100 facing the suction cup 101, and the shape of the guide protection part 116 is adapted to the shape of the contact part of the exposed surface of the product.

[0048] In this embodiment, the guide and protective part 116 is provided so that during the process of adsorbing and fixing the guide shell 100 toward the exposed surface of the product, the guide and protective part 126 can abut against the exposed surface of the product to guide the movement direction of the guide shell 100 and ensure that the guide shell 100 is accurately fitted onto the exposed surface of the product; and after the guide shell 100 is adsorbed and fixed to the exposed surface of the product, the suction cup 101 and the guide and protective part 116 cooperate to wrap the entire exposed surface of the lampshade, ensuring that the exposed surface of the lampshade will not collide with environmental parts and cause damage to the appearance during the assembly of the lampshade.

[0049] It is worth mentioning that the guide protection part 116 is made of thermoplastic elastomer, and the guide protection part 116 includes a surrounding ring, the width of which gradually decreases in the direction away from the working airbag 102.

[0050] Preferably, when the negative pressure generator is in normal operation, the end of the suction cup 101 away from the negative pressure generator extends out of the guide shell 100; when the negative pressure generator is in a negative pressure state, after the suction cup 101 is adsorbed and fixed to the exposed surface of the product, the end face of the suction cup 101 away from the negative pressure generator is flush with the end face of the guide shell 100 near the suction cup 101.

[0051] In this embodiment, to ensure sufficient contact area between the suction cup 101 and the exposed surface of the product, it is designed such that, under normal conditions, the end of the suction cup 101 away from the negative pressure generator extends out of the guide shell 100. During the process of adsorbing and fixing the suction cup 101 to the exposed surface of the product, as the suction cup 101 approaches, the contact area between the suction cup 101 and the exposed surface of the product gradually increases until the suction cup 101 is adsorbed and fixed to the exposed surface of the product, and the end face of the suction cup 101 is flush with the end face of the guide shell 100, so that the guide shell 100 will not shake relative to the lighting lamp 3 during operation and installation.

[0052] More preferably, a reinforcing pad 117 is provided at the end of the working airbag 102 away from the suction cup 101.

[0053] In this embodiment, by providing a reinforcing pad 117 on the working airbag 102 to increase the thickness of the working end of the working airbag 102 away from the suction cup 101, the service life of the working airbag 102 can be increased.
