Abstract
The utility model discloses an automobile safety belt coiler capable of preventing the generation of abnormal sound, which comprises a coiler framework and an upper fixed point support frame connected on the coiler framework, wherein a screw bolt installing hole is arranged on the coiler framework, and a screw bolt is connected with an automobile body through the installing hole. The utility model is characterized in that an installing button is positioned and connected on the upper fixed support frame, is clamped and connected with a process hole of the automobile body, is made of rubber materials, and has a space of at least 3mm from the automobile body. The utility model fully utilizes the existing process hole of the automobile body, and reduces the hole installation requirement of the automobile body, at the same time, the upper fixed support frame and the automobile body are separated by the installing button, the vibration direction of the coiler is restricted in the space, the coiler is fixed without vibration space in the theory, and the technical scheme of the utility model can effectively solve the problem of the generated abnormal sound caused by the resonance generation of the coiler and the automobile body of the automobile through the high sound absorption performance of the rubber.
Description
Technical field
The utility model relates to a kind of automobile safety belt retractor that can prevent to produce abnormal sound.
Background technology
In automotive development, safety strap is one of main safety performance spare, and it is had higher quality requirements.And taking-up device adopts the single-point mounting means usually, as shown in Figure 1,1 attachment point is only arranged, in the motion that only can limit 5 degree of freedom, therefore, can be because under certain road surface certain frequency, taking-up device is consistent with the auto body frequency, thereby resonate, produce abnormal sound, solve this abnormal sound for addressing this problem the main at present mode of increase attachment point that adopts.Common two-point belt mounting structure as shown in Figure 2 is made up of taking-up device framework and last fixed support, and last attachment point support is riveted together by two rivets and taking-up device framework.In use taking-up device framework and last fixed support and vehicle body are fixed by bolt.This structure is had relatively high expectations to the vehicle body local structure, needs to change the vehicle body existing structure usually and goes up support bracket fastened installation to satisfy.
Summary of the invention
The purpose of this utility model is to propose a kind of automobile safety belt retractor that can prevent to produce abnormal sound, and it can prevent that taking-up device and auto body from resonance taking place and produce abnormal sound under the condition that does not change body structure.
A kind of automobile safety belt retractor that can prevent to produce abnormal sound described in the utility model, comprise the taking-up device framework, be connected the last attachment point support on the taking-up device framework, on the taking-up device framework, be provided with bolt mounting holes, bolt is connected with car body by this mounting hole, it is characterized in that: one installs button is located by connecting on the fixed support, and this installs the auxiliary hole clamping of button and vehicle body; Thereby realize 2 installing and locating on vehicle body of automobile safety belt retractor.
Described a kind of automobile safety belt retractor that can prevent to produce abnormal sound, its described installation button adopts elastomeric material to make, and with vehicle body the spacing that has 3mm at least is arranged; Thereby avoided the metal piece direct contact and produced vibration friction abnormal sound; Button is installed according to existing vehicle body spare auxiliary hole size design, is directly utilized auxiliary hole to realize that attachment point is installed on the taking-up device.
Described a kind of automobile safety belt retractor that can prevent to produce abnormal sound, its described attachment point support of going up is located by connecting on the taking-up device framework by rivet.
The utility model has made full use of the existing auxiliary hole of vehicle body, reduced vehicle body mounting hole demand, going up simultaneously fixed support and vehicle body spare has had the installation button to be separated by, direction of vibration to taking-up device from the space retrains, theoretically taking-up device is fixed and the friction space, the high sound-absorbing of rubber causes this scheme to solve taking-up device and auto body generation resonance and to produce abnormal sound by actv..

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to a kind of automobile safety belt retractor that can prevent to produce abnormal sound shown in Figure 3, comprise taking-up device framework 1, be connected last attachment point support 2 on the taking-up device framework by rivet 5, be provided with bolt mounting holes 4 on the taking-up device framework, bolt is connected with car body by this mounting hole; One installs button 3 is located by connecting on the fixed support 2, and this installs the auxiliary hole clamping of button and vehicle body; Thereby realize 2 installing and locating on vehicle body of automobile safety belt retractor.
Described installation button 3 adopts elastomeric material to make, and with vehicle body the spacing that has 3mm at least is arranged; Thereby avoided the metal piece direct contact and produced vibration friction abnormal sound; Button is installed according to existing vehicle body spare auxiliary hole size design, is directly utilized auxiliary hole to realize that attachment point is installed on the taking-up device.
Taking-up device of the present utility model has adopted 2 mounting structures, and the direction of vibration to taking-up device from the space retrains, and theoretically taking-up device is fixed and the friction space.But in actual vibration,, under certain frequency, can produce vibration friction abnormal sound because of vibration if metal piece is in contact with one another by evidence.The present invention has thoroughly solved this problem, when vibration takes place, the last attachment point that contacts with vehicle body is the installation button 3 that rubber is made, has certain elasticity and thickness, guaranteed that with the good installation button 3 of vehicle body clamping last fixed support 2 has the spacing of 3mm at least with vehicle body, avoided the metal piece direct contact and produce vibration friction abnormal sound.
The automobile safety belt retractor of existing 1 attachment point of Fig. 1 only can limit the motion of 5 degree of freedom, therefore, can be because under certain road surface certain frequency, taking-up device is consistent with the auto body frequency, thereby resonates, and produces abnormal sound.
The automobile safety belt retractor of existing two attachment points of Fig. 2 is made up of taking-up device framework and last fixed support, and last attachment point support is riveted together by two rivets and taking-up device framework.In use taking-up device framework and last fixed support and vehicle body are fixed by bolt.This structure is had relatively high expectations to the vehicle body local structure, needs to change the vehicle body existing structure usually and goes up support bracket fastened installation to satisfy.
