In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0021] like Figure 1 , Figure 2 As shown, a wireless remote control handle 100 includes a handle body; the handle body 110 is a straight groove structure, used to snap into a straight hand push component 200; a pressure sensor 130, a wireless signal transmitting device and a mobile power supply are arranged in the handle body 110; the wireless signal transmitting device is electrically connected to the pressure sensor 130 and the mobile power supply respectively.

[0022] The wireless remote control handle is suitable for a trolley including the straight-line hand-pushing component 200. The handle body 110 is sleeved outside the straight-line hand-pushing component 200. The advantage of this structure is that the wireless remote control handle 100, the wireless signal receiving device and the motor can be installed on an ordinary trolley, so that the ordinary trolley can be transformed into an intelligent power-assisted trolley.

[0023] The pressure sensor 130, the wireless signal transmitter and the mobile power supply are dip-molded or meshed in the handle body 110. The three have the common characteristics of being thin and small in size. The pressure sensor 130 is commonly used in the form of a piezoresistive pressure sensor and a capacitive pressure sensor. The pressure sensor 130 is arranged in the area corresponding to the gripping part. Whether the handle body 110 is pushed by one hand or by both hands at the same time, the pressure sensor 130 can sense the pressure from the gripping part.

[0024] like Figure 1 As shown, as a further solution of the utility model: the wireless remote control handle 100 also includes a display screen 120, and the display screen 120 is embedded in the outer wall surface of the groove of the handle body 110, and the display screen 120 is electrically connected to the mobile power supply.

[0025] The display screen 120 mainly displays the magnitude of the pressure felt by the pressure sensor 130 to facilitate screen display or function indication.

[0026] like Figure 1 As shown, as a further solution of the present utility model: the display screen 120 is arranged on a side close to the groove edge 111.

[0027] No matter how the height of the hand push part is adjusted, in order to ensure the convenience of the trolley and from the perspective of visual safety, the eye height of a person is always higher than the hand push part. Therefore, the display screen 120 is arranged on one side of the groove edge 111. Even if it is arranged on the other side of the groove edge 111, it can be installed by rotating the angle of the handle body 110. In short, the purpose is to match the display screen 120 with the visual angle of a person after the handle body 110 is installed, so that the user can observe the display screen 120 conveniently.

[0028] like Figure 1 As shown, as a further solution of the present invention: the display screen 120 is arranged at the longitudinal center position of the handle body 110.

[0029] The display screen 120 is disposed at the longitudinal center of the handle body 110 , which is conducive to the left and right hands exerting the same force and maintaining body balance, and is also convenient for observing the display screen 120 .

[0030] like Figure 1 As shown, as a further solution of the present utility model: the handle body 110 is a straight groove structure with an end surface in the shape of a letter C or a U.

[0031] The straight-shaped hand push member 200 is in a columnar shape, preferably a cylindrical shape. This arrangement is convenient for gripping the handle body 110 and is conducive to exerting force to push the hand pusher.

[0032] like Figure 1 As shown, as a further solution of the present utility model: an opening 1111 is provided at the center of the two groove edges 111 of the handle body 110.

[0033] An opening 1111 is provided at the center of the two groove edges 111 of the handle body 110 . When the handle body 110 is buckled, the two sides thereof are slightly deformed and expanded to easily be buckled outside the I-shaped hand-pushing component 200 .

[0034] First embodiment

[0035] like Figure 1 As shown, as a further solution of the present invention: the handle body 110 is made of a hard elastic material.

[0036] The handle body 110 has a certain elasticity and hardness, such as polyurethane or ABS plastic or polycarbonate, so that the handle body 110 can be conveniently installed outside the straight-line hand-pushing component 200, and can also ensure that the handle body 110 is firmly buckled outside the straight-line hand-pushing component 200 after installation.

[0037] Second embodiment

[0038] The handle body 110 has very poor elasticity. During installation, the handle body 110 is first fixedly mounted on either end of the I-shaped hand push component 200 to form an assembly, and then the assembly is further installed with other components of the trolley.

[0039] Working principle:

[0040] A wireless signal receiving device, a processor and a motor are installed at other positions of the trolley, and the three are electrically connected in sequence. When pressure is applied to the wireless remote control handle, the pressure sensor transmits the sensed pressure to the wireless signal transmitting device, the wireless signal transmitting device sends a signal to the wireless receiving device, and the wireless receiving device transmits the signal to the processor, and then the processor transmits the processed force F1 to the motor, and finally the motor provides the trolley with a corresponding force F2 to assist the user. If the pressure applied to the wireless remote control handle is a thrust, the motor provides a forward force that matches the thrust; if the pressure applied to the wireless remote control handle is a pulling force, the motor provides a backward force that matches the pulling force; similarly, if no pressure is applied to the wireless remote control handle, the motor does not provide any force.

[0041] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
