Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycle instruments, in particular to a split side-button waterproof electric bicycle instrument. Background Art

[0002] The instrument panel of an electric bicycle displays important riding data during the trip, such as speed, distance, battery life and power gear, helping riders to read the data and control the power in the first place during riding. The button is one of the important components of the instrument panel.

[0003] The electric power bicycle instrument in the prior art has the following defects:

[0004] 1) At present, the waterproof structure design of the silicone side buttons of many instruments on the market is mostly a rubber-encapsulated structure. The plastic shell silicone encapsulation process has high requirements for materials and molds, resulting in high mold costs, low product yields, and non-universal use. One set of molds can only be used for one product;

[0005] 2) In order to reduce mold costs, a few silicone side buttons adopt a split gluing process. The side buttons and the plastic shell are manually glued together. Manual glue bonding is a technical job and is prone to defects such as glue overflow, glue deficiency, and button position misalignment, resulting in low production efficiency and low yield.

[0018] Figure 1 It is a schematic diagram of the exploded structure of the split side button waterproof electric bicycle meter of the embodiment of the utility model;

[0019] Figure 2 The utility model is a schematic cross-sectional view of a split side-button waterproof electric bicycle meter according to an embodiment of the utility model. DETAILED DESCRIPTION

[0020] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a split side-button waterproof electric bicycle instrument, including a lower cover 1, wherein a mounting groove 2 is provided inside the lower cover 1, and a main board 3 is fixed in the mounting groove 2. An upper cover 4 is fixed on the upper side of the lower cover 1, and a display screen 5 is fixed on the upper side of the upper cover 4, and the display screen 5 is preferably a liquid crystal display screen. A button 7 is fixed on the main board 3, and specifically, the button 7 is preferably welded and fixed on the lower side of the main board 3, and the instrument control command can be input through the button 7. A plurality of mounting openings 6 are provided on the side of the lower cover 1, and the mounting openings 6 are arranged on the outside of the button 7. The above-mentioned mounting openings 6 are preferably 2, and two buttons 7 are correspondingly arranged. An elastic keycap 8 is provided in the mounting opening 6, and the keycap 8 is preferably a silicone keycap, and the entire structure is formed in one piece.

[0022] Specifically, the keycap 8 of the embodiment of the utility model includes a body 81, which is detachably fixedly connected to the inner side of the mounting opening 6, and a avoidance groove 82 is provided in the middle of the inner side of the body 81. The outer end of the body 81 is closed, and a pressing portion 83 is provided in the middle of the outer end of the body 81. The pressing portion 83 is preferably protruding from the outer end surface of the body 81 for easy pressing. The inner end of the pressing portion 83 is connected to the outer end of the pressure column 84, and the inner end of the pressure column 84 passes through the avoidance groove 82 and abuts against the key 7. When the pressing portion 83 is pressed by a finger, the closed portion with a thinner thickness around the pressing portion 83 and between the body 81 will be deformed, so that the pressing portion 83 and the pressure column 84 move inward together, thereby pressing the key 7. It can be automatically reset after releasing the finger.

[0023] In order to facilitate the installation of the keycap 8, a clamping structure is preferably provided between the installation opening 6 and the body 81, and a pressing ring 9 is provided on the inner side of the avoidance groove 82. The clamping structure preferably includes two or more sets of clamping groove and clamping block matching structures. During installation, the keycap 8 is first installed into the installation opening 6, and then the pressing ring 9 is pressed into the avoidance groove 82, so as to avoid the separation of the clamping structure between the installation opening 6 and the body 81, ensure that the keycap 8 will not separate from the installation opening 6, and ensure the sealing effect between the keycap 8 and the lower cover 1.

[0024] An adaptive chamfered structure is provided on the inner side of the outer end of the pressing ring 9, and the chamfered structure can limit the inward movement position of the pressing portion 83 to avoid excessive force acting on the key 7, while having a better pressing tactile feeling.

[0025] In order to facilitate the fixation of the mainboard 3, it is preferred to set a plurality of fixing columns 10 on the inner side of the lower cover 1. The upper ends of the fixing columns 10 are provided with threaded holes. The mainboard 3 can be fixed to the upper side of the fixing columns 10 by means of a plurality of screws 11 threadedly connected in the threaded holes.

[0026] In order to ensure the sealing between the upper cover 4 , the lower cover 1 and the display screen 5 , it is preferred that the upper cover 4 , the lower cover 1 and the display screen 5 are all bonded and fixed.

[0027] The above is only a preferred embodiment of the utility model. It should be pointed out that for ordinary technicians in this technical field, other parts not specifically described belong to the prior art or common knowledge. Under the premise of not departing from the principle of the utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the utility model.
