Description

Technical Field

[0001] This utility model relates to the field of automotive sealing strip technology, specifically a rubber sound insulation sealing strip for automobiles. Background Technology

[0002] Automotive weatherstripping is a strip-shaped sealing structure used in automobiles to seal gaps and isolate the vehicle from the internal and external environments. It is typically made of rubber or soft plastic. Automotive weatherstripping is usually installed on doors, windows, hoods, trunks, and sunroofs, etc., and serves functions such as shock absorption, waterproofing, dustproofing, sound insulation, and decoration by filling various gaps and seams between vehicle body components.

[0003] When in operation, the automotive sealing strip absorbs and buffers the impact of the door closing pressure through the deformable bladder set on its upper part. However, due to structural limitations, the bladder structure has poor rebound support after compression, which easily leads to poor sealing of the door gap after the door is closed. Therefore, a rubber sound insulation sealing strip for automobiles is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a rubber sound insulation sealing strip for automobiles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber sound insulation sealing strip for automobiles, comprising a sealing strip body, an mounting strip, and a buffer strip seat. The mounting strip is disposed on the rear mounting side of the sealing strip body. A buffer cavity and a support cavity are sequentially disposed in the middle of the sealing strip body. The buffer cavity is installed on the upper part of the sealing strip body in a left-right split shape. The buffer strip seat is disposed between the two sets of buffer cavities. Buffer seats are evenly disposed on the upper part of the buffer strip seat. Soft flow holes are provided on both sides of the buffer seats.

[0006] The support capsule has a central support capsule in the middle of its inner cavity, and side support capsules on both sides of its inner cavity. The side support capsules have an arc-shaped partition in the middle of their inner cavity.

[0007] Preferably, the mounting strip is in the form of a strip, and the mounting strip is fixedly installed on the rear mounting side of the sealing strip body.

[0008] Preferably, the buffer cavities are arranged in pairs, with the two sets of buffer cavities symmetrically arranged on both sides of the upper part of the sealing strip, and the inner cross-section of the buffer cavities is rectangular.

[0009] Preferably, a strip mounting groove is provided in the middle of the two sets of buffer cavities, and the lower strip seat of the buffer strip seat is fixedly installed on the inner side of the strip mounting groove.

[0010] Preferably, multiple buffer bladder seats are provided, and several buffer bladder seats are fixedly arranged at equal intervals on the upper part of the buffer strip seat. The inner cavity of the buffer bladder seat is rectangular, and the slow flow hole is provided through both sides of the buffer bladder seat.

[0011] Preferably, the aforementioned central support cavity is fixedly disposed in the middle of the support cavity, and the inner cross-section of the central support cavity is circular.

[0012] Preferably, the side support cavities are arranged in pairs, with the two sets of side support cavities symmetrically arranged on both sides of the inside of the support cavities. The arc-shaped partition is fixedly installed in the middle of the side support cavities, and the cross-section of the arc-shaped partition is arc-shaped.

[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0014] This sealing strip adopts a double-cavity support structure with upper and lower layers. The upper part is equipped with two sets of separate buffer cavities. The two sets of buffer cavities with good buffering and energy absorption characteristics can buffer and absorb the downward pressure impact when the door is closed. While supporting and protecting the vehicle body structure, it can also effectively reduce the noise of the vehicle body when the door is closed. The lower part is equipped with a support cavity structure with an internal cavity reinforcement structure. The central support cavity and the arc-shaped partition in the support cavity form a cavity structure with high resilience support characteristics. After the door is closed, the buffer cavity can fit tightly against the inner wall of the door, which can effectively improve the gap sealing and sound insulation characteristics after the door is closed.

[0015] The system employs an airbag-like buffer support structure. Buffer strip seats are installed in the slots between two sets of buffer bladders. Multiple independent buffer bladder seats are located on the upper part of the buffer strip seats. The buffer bladder seats form a relatively closed bladder structure in the middle and have slow-flow holes on both sides. When the car door closes slowly, air is naturally discharged through the buffer bladders and buffer seats to complete the door closure buffer. When the car door closes quickly, air is blocked by the slow-flow holes and forms an inflation effect within the bladder of the buffer seat, effectively absorbing and buffering the impact of the rapidly closing car door. This effectively improves the energy absorption and buffering protection characteristics of the sealing strip. Attached Figure Description

Example

[0025] Please see Figure 1-5 This utility model provides a technical solution: a rubber sound insulation sealing strip for automobiles, including a sealing strip body 1, an mounting strip 2, and a buffer strip seat 3. Specifically, the sealing strip body 1 is made of a composite rubber material with excellent softness and resilience. The sealing strip body 1 adopts an adhesive installation method. To facilitate the connection and installation of the sealing strip body 1, as shown in the attached... Figure 2 As shown, the mounting strip 2 is fixedly installed on the rear mounting side of the sealing strip body 1. The mounting strip 2 is strip-shaped and has an adhesive surface at its rear. The adhesive surface can be made of acrylic sealant, which can ensure that the sealing strip body 1 is stably installed on the side of the car door after installation.

[0026] A dual-cavity support structure with upper and lower layers is adopted. To improve the buffering and energy absorption of the sealing strip 1, a buffer cavity 4 and a support cavity are sequentially arranged in the middle of the sealing strip 1. The buffer cavity 4 is used for energy absorption and buffering when the door closes, as shown in the attached diagram. Figure 3 As shown, the buffer bladders 4 are arranged in pairs, with two sets of buffer bladders 4 symmetrically arranged on both sides of the upper part of the sealing strip 1. The inner cross-section of the buffer bladder 4 is rectangular, which has good deformation energy absorption characteristics. The two sets of split buffer bladders 4 are arranged in the upper part. The two sets of buffer bladders 4 with good buffer energy absorption characteristics can buffer and absorb the downward impact when the door is closed, and can effectively reduce the noise of the door closing while supporting and protecting the vehicle body structure.

[0027] The support cavity is used for elastic support of the upper cavity structure. To improve the support characteristics of the support cavity, a central support cavity 6 is provided in the middle of the inner cavity of the support cavity, as shown in the attached figure. Figure 3 As shown, the central support cavity 6 is fixedly installed in the middle of the support cavity. The inner cross-section of the central support cavity 6 is circular, possessing excellent elastic support capacity and anti-structural aging characteristics. To improve the support capacity of the sides of the support cavity, side support cavities 5 are provided on both sides of the inner cavity of the support cavity. An arc-shaped partition 7 is provided in the middle of the side support cavity 5. The side support cavities 5 are arranged in pairs, and the two sets of side support cavities 5 are symmetrically arranged in the support cavity. Inside the bladder cavity, the arc-shaped partition 7 has a circular arc cross-section. The arc-shaped partition 7 is fixedly installed in the middle of the side support bladder cavity 5 to support and reinforce the middle cavity side of the side support bladder cavity 5. The middle support bladder cavity 6 and the arc-shaped partition 7 in the support bladder cavity form a bladder structure with high resilience support characteristics. After the door is closed, the buffer bladder cavity 4 can fit tightly against the inner wall of the door, which can effectively improve the gap sealing and sound insulation characteristics after the door is closed.

[0028] The buffer strip seat 3 is positioned between the two sets of buffer cavities 4 and works in conjunction with the buffer cavities 4 to form a closed-door buffer protection structure, as detailed in the attached diagram. Figure 3 As shown, to facilitate the connection and installation of the buffer strip seat 3, a strip seat mounting groove is provided in the middle of the two sets of buffer chambers 4. The lower strip seat part of the buffer strip seat 3 is fixedly installed to the inner side of the strip seat mounting groove by structural adhesive or integral hot-melt treatment. In order to achieve energy absorption and buffer protection, as shown in the attached figure... Figure 4 As shown, buffer seats 8 are evenly arranged on the upper part of the buffer strip seat 3. Multiple buffer seats 8 are provided, and several buffer seats 8 are fixedly arranged equidistantly on the upper part of the buffer strip seat 3, as shown in the attached diagram. Figure 5As shown, the inner cross-section of the buffer bladder seat 8 is rectangular, forming a relatively closed bladder structure inside. To facilitate air circulation, slow-flow holes 9 are provided on both sides of the buffer bladder seat 8. The slow-flow holes 9 are provided through the two side walls of the buffer bladder seat 8, adopting a similar airbag-like buffer support structure. A buffer strip seat 3 is installed in the groove between the two sets of buffer bladder cavities 4, and multiple independent buffer bladder seats 8 are provided on the upper part of the buffer strip seat 3. The middle of the buffer bladder seat 8 forms a relatively closed bladder structure, and slow-flow holes 9 are provided on both sides. When the car door closes slowly, the air is naturally discharged through the buffer bladder cavities 4 and works with the buffer bladder seats 8 to complete the door closing buffer. When the car door closes quickly, the air is blocked by the slow-flow holes 9 and forms an inflation effect in the bladder cavity of the buffer bladder seat 8, effectively absorbing and buffering the impact of the quickly closing car door, which can effectively improve the energy absorption and buffering protection characteristics of the sealing strip.

[0029] Working principle or structural principle: During installation, the sealing strip 1 is installed on the installation edge of the car door by means of adhesive strip 2. During the door closing process:

[0030] When the door closes slowly: the door closes slowly and comes into contact with the buffer bladder 4 and buffer seat 3 on the upper part of the sealing strip 1. During the contact process, the buffer bladder 4 and the upper buffer seat 8 of the buffer seat 3 are supported by the contact. Due to the slow deformation process, the air in the buffer seat 8 is discharged at a constant speed through the slow flow holes 9 on both sides. The energy absorption of the door closing impact is completed by the deformation of the bladder. At the same time, the impact force is transmitted to the lower support bladder through the buffer bladder 4 and the buffer seat 3. The elastic support of the side support bladder 5, the middle support bladder 6 and the arc-shaped partition 7 prevents the buffer bladder 4 and the buffer seat 3 from continuing to move downward.

[0031] When the door closes quickly: the door closes quickly and comes into contact with the buffer bladder 4 and buffer seat 3 on the upper part of the sealing strip 1. Under pressure, the buffer bladder 4 and the buffer seat 8 on the upper part of the buffer seat 3 deform. Due to the deformation process, the air in the buffer seat 8 cannot be discharged through the slow flow holes 9 on both sides in a short time. The air is blocked by the slow flow holes 9 and forms an inflation effect in the bladder of the buffer seat 8, which effectively absorbs and buffers the impact of the quickly closing door, thus achieving the avoidance buffer protection of the door. At the same time, the elastic support of the side support bladder 5, the central support bladder 6 and the arc-shaped partition 7 prevents the buffer bladder 4 and the buffer seat 3 from continuing to move downward.

[0032] After the door is closed: After the door is closed, the elastic support of the side support chamber 5, the central support chamber 6 and the arc-shaped partition 7 can make the upper buffer chamber 4 and the buffer strip seat 3 fit tightly with the inner edge of the door, so as to achieve a tight seal and protection of the door gap, which can effectively improve the gap sealing and sound insulation characteristics after the door is closed.

[0033] In summary, this sealing strip adopts a double-cavity support structure with upper and lower layers. The upper part features two sets of separate buffer cavities 4, which, with their excellent buffering and energy absorption characteristics, can buffer and absorb the downward impact when the door closes, effectively reducing noise during door closure while supporting and protecting the vehicle structure. The lower part features a support cavity structure with an internal cavity reinforcement structure. The central support cavity 6 and the arc-shaped partition 7 within this support cavity form a cavity structure with high resilience and support characteristics. After the door closes, the buffer cavity 4 can fit tightly against the inner wall of the door, effectively improving the seal of the gap after the door is closed. In addition to sound insulation characteristics, an airbag-like buffer support structure is adopted. A buffer strip seat 3 is installed in the groove between the two sets of buffer bladders 4. Multiple independent buffer bladder seats 8 are set on the upper part of the buffer strip seat 3. The buffer bladder seat 8 forms a relatively closed bladder structure in the middle and has slow flow holes 9 on both sides. When the car door closes slowly, the air is naturally discharged and works with the buffer bladder 4 to complete the door closing buffer through the buffer bladder 4. When the car door closes quickly, the air is blocked by the slow flow holes 9 and forms an inflation effect in the bladder of the buffer bladder seat 8, which effectively absorbs and buffers the impact of the quickly closing car door, and can effectively improve the energy absorption and buffer protection characteristics of the sealing strip.
