[0024] The present utility model will be further clarified below in conjunction with the accompanying drawings and specific embodiments. These embodiments are implemented on the premise of the technical solution of the present utility model. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model.

[0025] As Figures 1 to 5 shown, the embodiment of the present utility model provides an installation structure of an electric assist bicycle instrument. The instrument includes an instrument lower cover 1 and an instrument upper cover 2 adhesively fixed on the instrument lower cover 1. The installation structure of the instrument includes a snap connection seat 3 detachably and fixedly connected to the lower side of the instrument lower cover 1. An adapted connection structure is provided between the lower end of the snap connection seat 3 and the upper end of the split snap 4. This connection structure is used to detachably and fixedly connect the snap connection seat 3 and the split snap 4, and enables the snap connection seat 3 and the split snap 4 to have multiple installation directions. Except for the part where the upper end of the split snap 4 cooperates with the connection structure of the snap connection seat 3, the rest of the split snap 4 is the same as the prior art. Specifically, a locking assembly is provided at one end of the split snap 4. The locking assembly is preferably arranged at the lower end of the split snap 4. It specifically includes a locking bolt 5 inserted through the end of the split snap 4 and a nut 6 threadedly connected to the locking bolt 5. After the split snap 4 is sleeved on the cross tube 7 of the electric assist bicycle, the angle of the instrument can be adjusted by rotating around the cross tube 7 of the handlebar, and the locking bolt 5 can be tightened to fix it.

[0026] The connection structure of the embodiment of the present utility model preferably includes a card table 31 provided at the lower end of the snap connection seat 3. The cross section of the card table 31 is square. A card slot 41 is provided at the upper end of the split snap 4. The card table 31 is slidably connected in the card slot 41, and a limiting structure is also provided between the card table 31 and the card slot 41. Preferably, one end of the card slot 41 is closed. The above-mentioned limiting structure includes an inverted buckle 42 provided at the other end of the card slot 41, and a notch 32 cooperating with the inverted buckle 42 is provided in the middle of the four sides of the card table 31. When the card table 31 is inserted into the card slot 41, the inverted buckle 42 is pressed and deformed. After the card table 31 is in place, the inverted buckle 42 automatically bounces up by its own elasticity to play a limiting role, thereby fixing the snap connection seat 3 and the split snap 4. It should be noted that the positions of the above-mentioned card table 31 and card slot 41 can be interchanged, that is, a card slot is provided on the lower side of the snap connection seat 3, and a card table with a square cross section is provided at the upper end of the split snap 5. This connection structure enables the instrument to have 4 installation directions and can be selected and adjusted according to actual needs.

[0027] See Figure 3 and Figure 4 For the reverse buckle 42 of the embodiment of the present utility model, there are two setting methods. One is to directly set the reverse buckle 42 at the bottom of the card slot 41. When removing the buckle connecting seat 3 from the split buckle 4, only by using tools such as a flat-blade screwdriver to press down the reverse buckle 42 can the buckle connecting seat 3 be pushed outwards. The other is to connect the middle of the other end of the card slot 41 with the inner end of the lever 43. The outer end of the lever 43 extends out of the outside of the card slot 41, and the reverse buckle 42 is set on the upper side of the lever 43. When removing the buckle connecting seat 3 from the split buckle 4, only need to press down the lever 43 with hand to make the reverse buckle 42 ineffective, and then the buckle connecting seat 3 can be pushed outwards, which is convenient and fast. The inner section of the lever 43 is preferably horizontally arranged, and its upper surface is preferably flush with the bottom surface of the card slot 41. The middle of the lever 43 is bent so that the outer section of the lever 43 is arranged in a downward inclination. This can make the outer section of the lever 43 have enough spacing for easy pressing by hand.

[0028] In order to facilitate fixing the buckle connecting seat 3 on the lower side of the instrument lower cover 1, preferably, a plurality of through holes 8 are provided on the instrument lower cover 1, screws 9 are inserted in the through holes 8, and a plurality of threaded holes 10 matching with the screws 9 are provided on the buckle connecting seat 3. Preferably, the above-mentioned threaded holes 10 are two, and the two threaded holes 10 are preferably arranged at the diagonal positions at the upper end of the buckle connecting seat 3.

[0029] In order to prevent water from entering the instrument between the through hole 8 and the screw 9, preferably, a connecting sleeve 11 is arranged on the lower side of the instrument lower cover 1. The connecting sleeve 11 is integrally formed with the instrument lower cover 1. The upper end of the buckle connecting seat 3 is inserted into the connecting sleeve 11, and a sealing ring 12 is arranged between the upper end of the buckle connecting seat 3 and the connecting sleeve 11. Specifically, a sealing ring groove 13 can be arranged at the upper end of the buckle connecting seat 3, and the sealing ring 12 is arranged in the sealing ring groove 13. The sealing ring 12 is made of soft rubber material. The internal dimension of the connecting sleeve 11 is adapted to the upper end of the buckle connecting seat 3. After the upper end of the buckle connecting seat 3 is inserted into the inside of the connecting sleeve 11, the sealing ring 12 will generate a transverse deformation to ensure a good sealing effect.

[0030] During assembly, first install the sealing ring 12 into the sealing ring groove 13, then press the buckle connecting seat 3 into the connecting sleeve 11, then fix the instrument lower cover 1 and the buckle connecting seat 3 with two screws 9, then fix the instrument upper cover 2 on the instrument lower cover 1, then install the split buckle 4 on the buckle connecting seat 3 according to the required angular direction, and finally install the split buckle 4 on the handlebar cross tube 7 through the locking bolt 5 and the nut 6.

[0031] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, the other parts not specifically described belong to the prior art or common general knowledge. Without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
