TECHNICAL FIELD

[0001] The utility model relates to electric vehicle technical field, concretely is a kind of electric side stay and electric vehicle. BACKGROUND

[0002] Side stay is an important component of electric vehicle, mainly used to support the body when parking, so that it remains stable and upright. Electric side stay is a kind of side stay device with electric drive function developed on the basis of traditional electric side stay. It realizes automatic folding and unfolding of the side stay through an electric drive system, providing users with more convenient and intelligent use experience.

[0003] In the existing electric side stay design, the side stay is usually directly rigidly connected with the motor output end. During daily use, if someone inadvertently turns the side stay, the external force will be directly transmitted to the motor without buffering, causing damage to the internal components of the motor and increasing maintenance costs and use risks. Moreover, when the side stay is opened or folded, if the user's body is close to the side stay movement track, the side stay movement has no flexible adjustment, which is easy to be instantly pinched or hit. Therefore, we propose an electric side stay and electric vehicle to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0033] Embodiment one: please refer to Figures 1 to 8 A kind of electric side support, including fixed seat 1, for installation fixed on external equipment. The present embodiment further includes: shaft sleeve 2, side support body 3, motor 4, output shaft 5 and damping piece 6.

[0034] Specifically, the shaft sleeve 2 is rotatably connected to the fixed seat 1 and can rotate on the fixed seat 1. The side support body 3 is fixed to the outer ring of the shaft sleeve 2, and when an external force is applied, the side support body 3 can rotate along the axis of the shaft sleeve 2. The motor 4 is installed on the fixed seat 1 to provide driving force for the electric side support. The output shaft 5 is fixed to the output end of the motor 4, and the output shaft 5 is coaxially arranged with the shaft sleeve 2 and extends into the shaft sleeve 2. The damping piece 6 is connected between the output shaft 5 and the shaft sleeve 2, so that the output shaft 5 and the shaft sleeve 2 are connected in damping. When the motor 4 works, it can drive the output shaft 5 to rotate, thereby driving the shaft sleeve 2 to rotate through the damping piece 6, and further making the side support body 3 open or fold up.

[0035] When an external force is applied to the side support body 3, the damping member 6 can be used for buffering to avoid the external force being directly transmitted to the motor 4, thereby avoiding damage to the motor 4 and reducing maintenance costs and use risks. When the motor 4 drives the side support body 3 to rotate to open or fold, the damping connection provides a flexible adjustment mechanism. If the user's limbs accidentally approach the movement track of the side support body 3, it is not easy to cause serious pinching or collision injury to the human body, thereby reducing the risk of accidental injury.

[0036] In the embodiment, the fixing seat 1 is integrally formed with a first limiting part 7 and a second limiting part 8 for limiting the opening state or the folding state of the side support body 3, thereby effectively preventing the side support body 3 from being damaged or malfunctioning due to excessive rotation.

[0037] Especially, the first limiting part 7 and the second limiting part 8 are both provided with a position detector (not shown in the figure). The position detector can be a pressure sensor, a microswitch or the like. Taking the pressure sensor as an example, when the side support body 3 gradually approaches and finally contacts the first limiting part 7 or the second limiting part 8 during rotation, the pressure applied by the side support will cause the sensitive element inside the pressure sensor to deform, thereby changing the resistance value, and the change is converted into an electrical signal output through a circuit. Therefore, once the side support body 3 rotates to contact the first limiting part 7 or the second limiting part 8, the position detector will be triggered. At this time, the electrical signal will be quickly transmitted to the control system of the motor 4, and the control system will immediately issue an instruction to automatically power off the motor 4 after receiving the signal. This process ensures that the motor 4 will not continue to work after the side support body 3 has reached the specified position, effectively avoiding the overrunning of the motor 4, prolonging the service life of the motor 4, and saving electric energy.

[0038] In addition, the control system of the electric vehicle can determine whether the side support body 3 is in an open state or a folded state according to the signal transmitted by the position detector, so as to make feedback to improve safety. For example, when it is detected that the side support body 3 is in an open state, a warning can be issued through the instrument panel to remind the driver, or the start of the electric vehicle can be directly limited to avoid the electric vehicle driving when the side support is open, thereby ensuring the safety of the rider.

[0039] The damping member 6 will be described below.

[0040] The damping member 6 includes a plurality of first elastic sleeves 601 and a plurality of second elastic sleeves 602 arranged in sequence along the axial direction of the output shaft 5. A first connecting key 603 is integrally formed on the top of each first elastic sleeve 601, and a second connecting key 604 is integrally formed on the top of each second elastic sleeve 602. A first opening 605 is formed on the top of each first elastic sleeve 601 on the right side of the first connecting key 603, and a second opening 606 is formed on the top of each second elastic sleeve 602 on the left side of the second connecting key 604.

[0041] The above structure makes the damping element 6 an open elastic structure, thus providing damping force. However, considering the special open structure of the damping element 6, there will be a significant difference in the damping force generated during clockwise and counterclockwise rotation. To effectively eliminate this difference and ensure that the damping force is consistent during forward and reverse rotation, the opening directions of the first elastic sleeve 601 and the second elastic sleeve 602 need to be differentiated to ensure that the damping force is consistent during forward and reverse rotation.

[0042] In this embodiment, both the first elastic sleeve 601 and the second elastic sleeve 602 are interference-fitted onto the output shaft 5. Specifically, the first elastic sleeve 601 and the second elastic sleeve 602 are annular spring sheets with different opening directions. The inner diameter of these annular spring sheets is smaller than the diameter of the output shaft 5, and they form an interference fit when assembled. This causes the opening of the annular spring sheets to be enlarged, and through elastic deformation, the annular spring sheets are always tightly held onto the output shaft 5, thereby generating rotational friction.

[0043] The inner ring of the bushing 2 has a keyway 9, into which each of the first connecting keys 603 and each of the second connecting keys 604 extends. When the output shaft 5 rotates, it drives the first elastic sleeve 601 and the second elastic sleeve 602 to rotate synchronously. Through the interaction between the connecting keys and the keyway 9, the bushing 2 also rotates, thereby realizing the opening or closing action of the side support body 3. At the same time, the rotational friction generated by the annular spring plate holding the output shaft 5 provides a damping effect for the rotational motion.

[0044] It is worth mentioning that a limiting ring 10 is sleeved at one end of the output shaft 5, which can axially limit the damping member 6 and prevent the damping member 6 from shifting and falling off along the axial direction of the output shaft 5. It should be noted that the limiting ring 10 can be a retaining ring, a spacer, or other means to achieve axial limiting.

[0045] Additionally, a sealing ring 11 is fitted onto the output shaft 5 at the other end of the damping element 6. In this embodiment, the sealing ring 11 is an O-ring, which is dustproof and waterproof, preventing debris from entering the bushing 2 and affecting the normal use of the damping element 6.

[0046] Example 2: This example also proposes an electric vehicle, including the electric side stand as described in Example 1, and a vehicle body. The fixed seat 1 is fixedly installed on the vehicle body and can automatically open the side stand body 3 to support the vehicle body.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
