[0014] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. It should be understood that the present application is not limited by the example embodiments disclosed herein. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0015] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0016] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "plurality" is two or more unless otherwise specifically defined.

[0017] In the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0018] Please refer to Figures 1 to 3 , in the embodiments of the present utility model, a novel electric push rod structure includes: a driving motor 1, a transmission component 5, a support seat 2, a telescopic component 6, a telescopic inner tube 4, and an outer tube 3;

[0019] The driving motor 1, the transmission assembly 5, and the telescopic assembly 6 are all installed on the support base 2, and the transmission cooperation between the driving motor 1 and the telescopic assembly 6 is realized through the transmission assembly 5; the outer sleeve 3 is sleeved on the telescopic inner tube 4, and the telescopic inner tube 4 is in transmission cooperation with the telescopic assembly 6;

[0020] During operation, the driving power of the driving motor 1 is transmitted to the telescopic assembly 6 through the transmission assembly 5, and the rotational movement of the driving motor 1 is converted into a linear reciprocating movement of the telescopic inner tube 4 on the outer sleeve 3 through the telescopic assembly 6;

[0021] The transmission assembly 5 includes: a helical gear 51 and a transmission bevel gear 52. The helical gear 51 is in transmission cooperation with the transmission tooth shaft of the driving motor 1 and the transmission bevel gear 52 respectively;

[0022] The telescopic assembly 6 includes: a transmission lead screw 61 and a sliding nut 62 nested on the transmission lead screw 61. The telescopic inner tube 4 is arranged on the transmission lead screw 61, and the sliding nut 62 is fixedly connected to the top end of the telescopic inner tube 4; and the top end of the transmission lead screw 61 is concentrically arranged with the transmission bevel gear 52. During operation, the driving motor 1 drives the transmission lead screw 61 to rotate, so that the sliding nut 62 reciprocates along the axial direction of the transmission lead screw 61, thereby realizing the linear reciprocating telescopic operation of the telescopic inner tube 4.

[0023] Furthermore, a set of outwardly extending detection brackets 64 are arranged on the sliding nut 62; and a set of travel switches 65 are respectively arranged at the upper and lower ends of the inner wall of the outer sleeve 3. The travel switches 65 are located at the tail end position of the outer sleeve 3. During the process of the sliding nut 62 driving the telescopic inner tube 4 to perform linear reciprocating telescopic operation, when the detection bracket 64 travels into the detection range of the travel switch 65, it means that the telescopic inner tube 4 reaches the maximum working stroke, and the travel switch 65 will send a working signal to the driving motor 1 to control the driving motor 1 to stop or perform reverse output.

[0024] Furthermore, the transmission tooth shaft of the driving motor 1 and the axial movement direction of the telescopic inner tube 4 are designed in a parallel structure, making the overall structure more compact, effectively reducing the overall structure volume, and making the appearance design of the electric push rod more concise, intuitive, and generous.

[0025] It should also be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.

[0026] The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
