Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. In contrast, when an element is referred to as being "directly on" another element, there are no intervening ele...

Abstract

The invention relates to an overload protector and an electric supporting rod. The overload protector comprises a connecting pin, an embracing piece, a transmission base, an elastic adjusting piece and a shell which are sequentially sleeved from inside to outside. The embracing piece is used for making the connecting pin in separable transmission connection with the transmission base. The elasticadjusting piece is used for making the transmission base in transmission connection with the shell. The connecting pin is provided with a connecting end penetrating out of the transmission base. The connecting end is used for being in transmission connection with a motor reduction gearbox of the electric supporting rod. The end, away from the connecting end, of the shell is used for being in transmission connection with a lead screw of the electric supporting rod. By means of the overload protector, the overload protection of the electric supporting rod can be realized, and meanwhile the electric supporting rod can have high concentricity without producing abnormal sounds.

Description

Technical field [0001] The invention relates to the technical field of auto parts, in particular to an overload protector and an electric strut. Background technique [0002] At present, few electric struts used for car tailgates on the market have an overload protection function. When the car tailgate is quickly manually opened and closed, the reverse force can easily damage the motor gearbox and the motor in the struts. Although some struts with overload protectors can achieve overload protection, due to their poor concentricity, the sound pressure level of the struts increases, which will produce more serious abnormal noises, which will affect the performance of the struts. Summary of the invention [0003] Based on this, it is necessary to solve the above problems and provide an overload protector and an electric strut. The overload protector can realize the overload protection of the electric strut, and at the same time, it can also make the electric strut have a high degree ...
