The demand for back door motorized support bars is increasing for new users, which can provide a more automated experience. Its structure plays crucial effect to back of body door connection and support, and traditional back of body door electric stay bar has satisfied the function convenience of back of body door automatic switching, and the NVH of vaulting pole body under whole car driving considers not enough. Electric supporting rod working principle: the motor drives the internal mechanism to enable the inner rod to do telescopic motion relative to the outer rod. The inner and outer rods are respectively connected to the vehicle body and the back door side, and in a closed state, a certain size gap exists in a matching relationship, and the gap size consistency is not easy to control due to the limitation of the arrangement of internal mechanisms of the inner and outer rods and manufacturing deviation (the outline degree, roundness, assembly coaxiality and the like of the rods). In the running process of the vehicle, excitation vibration with different degrees is encountered, and the inner rod and the outer rod are inevitably impacted to generate vibration noise.

Disclosure of Invention

The utility model aims to provide an electric support rod and an automobile, wherein limit ribs are added at the tail end of an inner rod of a support rod, the limit ribs can be filled in gaps between the inner rod of the support rod and an outer rod of the support rod, the clearance fit relation between the inner rod of the support rod and the outer rod of the support rod can be improved, the defects of profile degree, roundness and coaxiality caused by manufacturing deviation are avoided, impact sound between the outer rod of the support rod and the inner rod of the support rod is generated, vibration noise between the electric support rods under driving road conditions can be effectively reduced through structural limit, and the structural change of the electric support rod is small.

The technical scheme of the utility model is as follows:

the utility model provides an electric support bar, comprising:

the outer pole of the stay bar and inner pole of the stay bar, one end of the outer pole of the stay bar is used for articulating with fixed point of the car body, one end of the inner pole of the stay bar is used for articulating with fixed point of the back door;

the stay bar inner rod is provided with a limiting rib in a protruding mode towards the outer peripheral wall of one end of the stay bar outer rod, and after the stay bar inner rod stretches into the stay bar outer rod, the limiting rib is limited in a gap between the stay bar inner rod and the stay bar outer rod.

Preferably, the spacing rib forms clearance fit with the gap between the stay bar inner rod and the stay bar outer rod.

Preferably, the limit ribs are multiple, and the limit ribs are uniformly distributed on the outer peripheral wall of the inner rod of the stay bar.

Preferably, the limit rib and the stay bar inner rod are integrally formed.

The utility model also provides an automobile comprising the electric supporting rod.

The beneficial effects of the utility model are as follows:

through increase spacing muscle in the end of vaulting pole inner rod, after the vaulting pole inner rod stretches into the vaulting pole outer pole in, spacing muscle can be filled in the clearance of vaulting pole inner rod and vaulting pole outer pole, can improve vaulting pole inner rod and vaulting pole outer pole clearance fit relation, avoid producing the impact sound between vaulting pole outer pole and the vaulting pole inner rod because of the profile degree, circularity, the axiality that the manufacturing deviation produced, can effectively reduce the vibration noise under the road conditions of traveling between the electric supporting rod through the structure spacing, and it is little to electric supporting rod own structural modification.

Detailed Description

Embodiments of the present utility model will be described below with reference to the accompanying drawings. Since the core technical points of the present utility model need to be protected, the illustrated embodiments are only a part of the content of the present utility model, but all fall within the scope of the protection of the present utility model.

Referring to fig. 1 to 5, the present embodiment provides an electric support bar including a stay outer bar 1 and a stay inner bar 2.

The stay bar outer rod 1 is hinged with the vehicle body fixed point 3, the stay bar inner rod 2 is hinged with the back door fixed point 4, and the connection relation between the stay bar outer rod 1 and the vehicle body and between the stay bar inner rod 2 and the back door all belong to the prior art.

The electric supporting rod assembly structure provided by the utility model can reduce vibration noise generated by the supporting rod body and improve NVH quality in the whole vehicle running process.

Referring to fig. 3 and 4, by adding a plurality of uniformly arranged limit ribs 5 on the peripheral wall of the tail end of the stay bar inner rod 2 facing the stay bar outer rod 1, the limit ribs 5 are limited in the gap between the stay bar inner rod 2 and the stay bar outer rod 1 in the electric stay bar closed state, and the matching size between the stay bar inner rod 2 and the stay bar outer rod 1 is improved.

Referring to fig. 5, the limit rib 5 and the stay bar inner rod 2 are integrally formed, and form a better matching relationship with the stay bar outer rod 1. The stay bar inner rod 2 and the limit rib 5 are made of plastics, after the limit rib 5 is filled into the gap, the limit rib 5 forms clearance fit with the gap, and the limit rib 5 reduces the vibration amplitude of the stay bar outer rod 1.

By adopting the structure, the inner rod and the outer rod of the electric supporting rod are enabled to effectively improve the NVH of the whole vehicle running by reducing the vibration amplitude under the same road condition, and the vibration noise is improved.

Through increase spacing muscle in the end of vaulting pole inner rod, after pole 2 stretches into in pole outer pole 1 in the vaulting pole, spacing muscle 5 can be filled in pole 2 in the vaulting pole and pole outer pole 1's clearance, can improve pole 2 in the vaulting pole and pole outer pole 1 clearance fit relation, avoid producing profile tolerance, circularity, axiality inadequately because of manufacturing deviation, produce the impact sound between pole outer pole 1 and the pole inner pole 2, can effectively reduce the vibration noise under the road conditions of traveling between the electric supporting rod through the structure spacing, and it is little to electric supporting rod own structural modification.

Although only one or a few examples of the present utility model have been described herein, it will be appreciated by those skilled in the art that the present utility model may be implemented in many other ways without departing from the logic and basic framework thereof.
