Description

Technical Field

[0001] The present invention relates to the technical field of automotive design and manufacturing, and particularly to a sill trim support device on an automotive support member. Background Art

[0002] A sill trim is a functional and decorative component installed at the threshold position of a vehicle or building entrance. In the automotive field, it is usually made of metal or high-strength plastic materials to cover the gap between the body sheet metal and the door floor, protecting the car paint from being scratched by the soles when getting in and out of the car. At the same time, through processes such as polishing, wire drawing, and chrome plating, the visual texture is enhanced. Some vehicle models also integrate lighting strips or brand logos to strengthen the sense of luxury.

[0003] Existing sill trims are mostly installed by snap connection. Align the snaps on the sill trim with the slots on the body sheet metal and press hard to make the snaps snap into the slots. The fixation is achieved by the elastic deformation of the snaps and the tight fit of the slots. Although the installation method is simple, the installation position of the sill trim is relatively compact, and the operating space around the snaps is narrow. When disassembling, it is difficult to use a suitable tool to assist in disassembly, and it often causes damage to the sill trim, resulting in it being unable to be used continuously.

[0004] Moreover, with the development of modern intelligent vehicle technology, the functions of the vehicle's electrical appliances are increasing, and the wiring harnesses used to connect various electrical devices are also increasing day by day. Various wiring harnesses are arranged in the middle sill part of the car. However, when the sill is stepped on, there is a risk of bending downward, which will then squeeze the internal wiring harnesses, increasing the risk of damage to the wiring harnesses. Summary of the Invention

[0005] The purpose of the present invention is to provide a sill trim support device on an automotive support member, which effectively solves the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions.

[0007] A sill trim support device on an automotive support member includes a sill trim and a body sheet metal. On one side of the outer surface of the body sheet metal, a fixing plate is provided, and both the fixing plate and one side wall of the body sheet metal are provided with insertion holes. On both sides of the bottom of the sill trim, fixing columns are installed. The outside of the fixing column is installed with a tube body through a translation mechanism, and the translation mechanism can drive the tube body to move horizontally away from the insertion hole. Inside the tube body, a plug rod is installed through an elastic mechanism. The plug rod is adapted to the insertion hole, and the elastic mechanism can apply an elastic force to the plug rod in the direction of the insertion hole.

[0008] Thus, through the setting of the elastic mechanism, the plug rod can be automatically inserted into the jack, completing the rapid connection of the threshold trim and the body sheet metal. Through the setting of the translation mechanism, the tube body can be driven to move horizontally away from the jack, and then the plug rod can be driven to be pulled out of the jack, achieving the purpose of quickly removing the threshold trim. Moreover, the operation is simple, not restricted by space, and can ensure the structural integrity of the threshold trim, avoiding violent removal.

[0009] Furthermore, the elastic mechanism includes a guide rod inserted inside the tube body, and the plug rod is installed at one end of the guide rod. A head is installed at the other end of the guide rod, and the head is in limiting sliding connection with the inner part of the tube body. A spring is arranged inside the tube body, and the two ends of the spring are respectively abutted against the inner wall of the tube body and the head.

[0010] Furthermore, the translation mechanism includes a bottom plate installed at the bottom of the fixed column. An L-shaped connecting plate is installed in the bottom plate in a limiting sliding manner, and the tube body is installed at the end of the L-shaped connecting plate. A tension spring is connected to the outer surface of the L-shaped connecting plate, and the end of the tension spring is connected to the outer surface of the fixed column. A sleeve is sleeved on the outer surface of the fixed column. A shoulder is arranged on the outer surface of the sleeve near its bottom, and the shoulder abuts against the tube body. A first magnetic block is arranged on the outer surface of the sleeve near its top, and a first iron sheet is installed on the top wall of the threshold trim.

[0011] Furthermore, a second magnetic block is arranged on the outer surface of the fixed column between the shoulder and the bottom plate, and a second iron sheet is arranged on the lower surface of the shoulder.

[0012] Furthermore, anti-slip stripes are arranged on the upper surface of the threshold trim.

[0013] Furthermore, notches are arranged on the anti-slip stripes, and the notches correspond to the first magnetic blocks.

[0014] Furthermore, the support block is of an inverted triangular structure, the number of wire harness channels is three, and the three wire harness channels correspond to the three top corners of the support block.

[0015] Furthermore, the two side corners of the inner wall of the threshold trim are in arc transition, and ribs are arranged at the arc transition.

[0016] Furthermore, balls are arranged at the end of the tube body facing the shoulder, and the balls abut against the shoulder.

[0017] Furthermore, rubber pads are arranged on the inner walls of the wire harness channels.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0019] 1. With the translation mechanism provided in the present invention, when it is necessary to extract the plug from the socket, only a strong magnet needs to be placed on the outer surface of the sill trim and aligned with the first magnet. Using the principle of like poles repelling each other, the sleeve is pushed downward to separate the tube body from the shoulder. Therefore, under the action of the tension spring, the plug can be pulled out from the socket, so that the quick removal of the sill trim can be realized, and the operation is simple, not restricted by space, and the integrity of the sill trim structure can be ensured, avoiding the situation of violent removal.

[0020] 2. With the support block and three wire harness channels provided in the present invention, the arrangement of three wire harnesses can be realized, and the wire harnesses are isolated from each other, avoiding mutual interference between the wire harnesses. Moreover, the support block also provides a support function between the sill trim and the body sheet metal, improving the structural strength of the sill trim. And due to the stability of the triangle, when the sill trim is stepped on, the deformation of the support block is small, reducing the possibility of the wire harness being squeezed.

DETAILED DESCRIPTION OF THE INVENTION

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 5 , a sill trim support device on an automotive support member provided by the present invention includes a sill trim 1 and a body sheet metal 2. A fixing plate 201 is provided on one side of the outer surface of the body sheet metal 2, and insertion holes 202 are provided on both the fixing plate 201 and a side wall of the body sheet metal 2. Fixed columns 103 are installed on both sides of the bottom of the sill trim 1. A tube 104 is installed on the outside of the fixed column 103 through a translation mechanism 4, and the translation mechanism 4 can drive the tube 104 to move horizontally away from the insertion hole 202. An insertion rod 105 is installed inside the tube 104 through an elastic mechanism 3. The insertion rod 105 is adapted to the insertion hole 202, and the elastic mechanism 3 can apply an elastic force to the insertion rod 105 in the direction of the insertion hole 202.

[0029] During use, due to the setting of the elastic mechanism 3, when the insertion rod 105 is aligned with the direction of the insertion hole 202 and the sill trim 1 is pressed downward, the insertion rod 105 is squeezed and contracted by the arc-shaped inner wall of the body sheet metal 2. When the insertion rod 105 descends to align with the insertion hole 202, it then pops out and inserts into the insertion hole 202 to complete the fixation. Due to the setting of the translation mechanism 4, the tube 104 can be driven to move horizontally away from the insertion hole 202, thereby driving the insertion rod 105 to be pulled out of the insertion hole 202, achieving the purpose of quickly removing the sill trim 1. The operation is simple, not limited by space, and can ensure the structural integrity of the sill trim 1, avoiding violent removal.

[0030] Moreover, due to the setting of the support block 101 and the wire harness channel 102, not only can a separate wire routing channel be provided for the wire harness, but the support block 101 also plays a supporting role between the sill trim 1 and the body sheet metal 2, improving the stability of the overall structure, reducing the deformation of the sill trim 1 when stepped on, and reducing the possibility of the wire harness being squeezed.

[0031] Preferably, the elastic mechanism 3 includes a guide rod 301 inserted into the tube 104, and the insertion rod 105 is installed at one end of the guide rod 301. A end head 302 is installed at the other end of the guide rod 301, and the end head 302 is in limited sliding connection with the inside of the tube 104. A spring 303 is provided inside the tube 104, and both ends of the spring 303 are in contact with the inner wall of the tube 104 and the end head 302 respectively.

[0032] When the insertion rod 105 and the arc-shaped inner wall of the vehicle body sheet metal 2 are squeezed against each other, the insertion rod 105 can be driven to drive the guide rod 301 to contract into the interior of the tube body 104, and the spring 303 is squeezed by the end 302. At this time, the spring 303 stores energy. When the insertion rod 105 is aligned with the insertion hole 202, the spring 303 in the energy storage state releases elastic force, which can push the guide rod 301 to move outwards, and then drive the insertion rod 105 to insert into the insertion hole 202 to achieve the purpose of fixation.

[0033] Preferably, the translation mechanism 4 includes a bottom plate 401 installed at the bottom of the fixed column 103. An L-shaped connecting plate 402 is installed in the bottom plate 401 in a limited sliding manner, and the tube body 104 is installed at the end of the L-shaped connecting plate 402. A tension spring 403 is connected to the outer surface of the L-shaped connecting plate 402, and the end of the tension spring 403 is connected to the outer surface of the fixed column 103. A sleeve 404 is sleeved on the outer surface of the fixed column 103. A shoulder 405 is provided on the outer surface of the sleeve 404 near its bottom, and the shoulder 405 abuts against the tube body 104. A first magnetic block 407 is provided on the outer surface of the sleeve 404 near its top, and a first iron sheet 406 is installed on the top wall of the threshold trim 1.

[0034] When it is necessary to pull out the insertion rod 105 from the insertion hole 202, only need to place a strong magnet on the outer surface of the threshold trim 1 and align it with the first magnetic block 407. Using the principle of like poles repelling each other, the sleeve 404 is pushed to slide downwards, so that the tube body 104 is separated from the shoulder 405. Therefore, under the action of the tension spring 403, the insertion rod 105 can be pulled out from the insertion hole 202, so that the threshold trim 1 can be quickly removed, and the operation is simple, not restricted by space, and can ensure the structural integrity of the threshold trim 1, avoiding the situation of violent removal.

[0035] Preferably, a second magnetic block 5 is provided on the outer surface of the fixed column 103 between the shoulder 405 and the bottom plate 401, and a second iron sheet 501 is provided on the lower surface of the shoulder 405.

[0036] When the sleeve 404 slides downwards on the outer surface of the fixed column 103, the distance between the second iron sheet 501 and the second magnetic block 5 is shortened. At this time, the second magnetic block 5 generates an adsorption force on the second iron sheet 501. Since the upper end of the sleeve 404 is pushed by like poles repelling each other and the lower end is attracted by opposite poles, under the combined action of the two forces, the second iron sheet 501 can be adsorbed together with the second magnetic block 5 to better pull out the insertion rod 105 from the insertion hole 202

[0037] Preferably, anti-slip stripes 6 are provided on the upper surface of the threshold trim 1.

[0038] Through the setting of the anti-slip stripes 6, the friction force on the surface of the threshold trim 1 can be increased, the anti-slip effect can be enhanced, and the anti-slip stripes 6 also increase the wall thickness of the threshold trim 1 to a certain extent and improve its structural strength.

[0039] Preferably, a notch 601 is provided on the anti-slip stripe 6, and the notch 601 corresponds to the first magnet 407.

[0040] Through the arrangement of the notch 601, the powerful magnet can directly contact the surface of the sill trim 1, reducing the distance between the powerful magnet and the first magnet 407 and providing a stronger repulsive force.

[0041] Preferably, the support block 101 has an inverted triangular structure, the number of wire harness channels 102 is three, and the three wire harness channels 102 correspond to the three top corners of the support block 101.

[0042] The arrangement of three wire harnesses can be realized, and the wire harnesses are isolated from each other, avoiding mutual interference between the wire harnesses. Moreover, the support block 101 also provides a supporting effect between the sill trim 1 and the body sheet metal 2, improving the structural strength of the sill trim 1. And due to the stability of the triangle, when the sill trim 1 is stepped on, the deformation of the support block 101 is small, reducing the possibility of the wire harness being squeezed.

[0043] Preferably, the two side corners of the inner wall of the sill trim 1 are in arc transition, and ribs 7 are arranged at the arc transition.

[0044] Through the arrangement of the ribs 7, the structural strength of the sill trim 1 is further enhanced, reducing the deformation amount generated when it is stepped on.

[0045] Preferably, a ball 8 is arranged at the end of the pipe body 104 facing the shoulder 405, and the ball 8 abuts against the shoulder 405.

[0046] Through the arrangement of the ball 8, the friction between the pipe body 104 and the shoulder 405 is greatly reduced, so that when the sleeve 404 slides downward, the resistance generated by its abutment with the pipe body 104 can be ignored.

[0047] Preferably, a rubber pad 9 is arranged on the inner wall of the wire harness channel 102.

[0048] The rubber pad 9 can protect the wire harness from abrasion, improving the reliability and safety of the wire harness.

[0049] The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding in the existing technology.

Therefore, in all respects, the embodiments should be regarded as exemplary and non-restrictive.
