Description

Technical Field

[0001] The utility model relates to the technical field of timing equipment for the blind, in particular to an electromagnetically driven timing equipment for the blind. Background Art

[0002] In the prior art, Figure 1 As shown in the figure, the current solution for similar timing equipment for the blind is to set a magnet on the watch hand. When the watch hand rotates, the magnet directly drives the magnetic beads set on the outside to roll and identify the time. However, due to the weight of the magnet itself and in order to support the weight of the magnet and ensure that the watch hand does not deform, the entire watch hand needs to be made relatively thick. After passing the drop test and when consumers wear it daily, the watch hand will fall off the needle shaft of the watch movement, or the strong inertial impact force will cause damage to the precision watch movement.

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0051] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0053] In related technologies, such as Figure 1 As shown in the figure, the current solution for similar timing equipment for the blind is to set a magnet on the watch hand.

However, due to the weight of the magnet itself and in order to support the weight of the magnet and ensure that the watch hand does not deform, the entire watch hand needs to be made relatively thick. After passing the drop test and when consumers wear it daily, the watch hand will fall off the needle shaft of the watch movement, or the strong inertial impact force will cause damage to the precision watch movement.
