[0043] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0044] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0045] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0046] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0047] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0048] The following first describes in detail the support cup 1 according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0049] like Figures 1 to 9 As shown, the cup 1 according to the embodiment of the utility model comprises: a shell 10.

[0050] Specifically, the housing 10 has a mounting groove 11 suitable for accommodating the battery 300. The mounting groove 11 penetrates the surface of the housing 10 along a first direction and forms a notch 12. The first direction, the second direction and the third direction are perpendicular to each other. The cross section obtained by cutting the mounting groove 11 with a plane perpendicular to the first direction is the cross section of the mounting groove 11. In the second direction, the maximum length of the cross section of the mounting groove 11 is L1. In the third direction, the maximum length of the cross section of the mounting groove 11 is L2, and L1>L2.

[0051] In other words, the cup 1 according to the embodiment of the utility model is mainly composed of a shell 10. The shell 10 may be provided with a mounting groove 11, and at least a portion of the mounting groove 11 may be adapted to the battery 300 to accommodate the battery 300. The battery 300 may be cylindrical.

[0052] The mounting groove 11 can extend along a first direction, and in the first direction, the mounting groove 11 penetrates the outer surface of the shell 10 to form a groove 12, that is, the first direction can be the depth direction of the mounting groove 11, and the battery 300 can be inserted into the mounting groove 11 through the groove 12, and the mounting groove 11 can limit the battery 300.

[0053] In addition, for ease of explanation, a section plane may be defined, which is perpendicular to the first direction. Since the second direction and the third direction are perpendicular to the first direction respectively, the section plane is parallel to the second direction and the third direction respectively.

[0054] The cross section obtained by cutting the mounting groove 11 with the cutting plane can be the cross section of the mounting groove 11. The shape of the cross section of the mounting groove 11 can be a regular figure or an irregular figure, which is not limited here. In the second direction, the distance between the two farthest points on the cross section of the mounting groove 11 is L1, and in the third direction, the distance between the two farthest points on the cross section of the mounting groove 11 is L2. Let L1>L2, so that the reduction between the mounting groove 11 and the battery 300 in the third direction can be smaller, thereby limiting the battery 300 in the third direction, and at the same time, the outer peripheral surface of the battery 300 is spaced apart from the inner wall surface 13 of the mounting groove 11 in the second direction to form a larger gap.

[0055] After the weighing of the battery 300 is completed, the conveying mechanism 200 can clamp the battery 300 in the support cup 1 through the clamp 201. Since there is a large gap between the outer peripheral surface of the battery 300 and the inner wall surface 13 of the mounting groove 11 in the second direction, the lateral force of the clamp 201 of the conveying mechanism 200 along the second direction only acts on the battery 300, and will not be transmitted to the support cup 1 and the scale body 2. This can avoid the weighing process being disturbed by the lateral force of the clamp 201, which is beneficial to improving the measurement accuracy and precision of the weighing.

[0056] It should be noted that the cross-section of the above-mentioned mounting groove 11 can be obtained by cutting the mounting groove 11 with any cutting plane perpendicular to the first direction, so that when the battery 300 enters the mounting groove 11, the outer peripheral surface of the battery 300 does not contact and transmit force to the inner wall surface 13 of the mounting groove 11 in the second direction.

[0057] Therefore, according to the cup 1 of the embodiment of the utility model, a mounting groove 11 is arranged in the outer shell 10 of the cup 1, so that the maximum length of the cross section of the mounting groove 11 in the second direction is greater than the maximum length of the cross section in the third direction. This can not only enable the mounting groove 11 to limit the battery 300 in the third direction to prevent the battery 300 from falling over, but also avoid the contact and force transmission between the clamping jaw 201 and the mounting groove 11 in the second direction when clamping the battery 300, thereby avoiding the lateral force from being transmitted to the cup 1 and the scale body 2 and damaging the scale body 2, which is beneficial to improving the accuracy and precision of weighing measurement.

[0058] In some specific embodiments, the first direction may be a vertical direction, and the second direction and the third direction may be two horizontal directions perpendicular to each other. The battery 300 may be inserted into the mounting groove 11 along the vertical direction. The cross section of the mounting groove 11 may be a cross section obtained by cutting the mounting groove 11 with a horizontal plane.

[0059] According to an embodiment of the present invention, the mounting groove 11 is a waist-shaped groove, the second direction is the length direction of the waist-shaped groove, and the third direction is the width direction of the waist-shaped groove.

[0060] Specifically, any cross section of the mounting groove 11 may be in the shape of a waist, and the waist has a length direction and a width direction. The profile of the cross section of the mounting groove 11 is mainly composed of two straight sides and two semicircular arc sides, the two straight sides may extend along the second direction, and the two straight sides may be spaced apart along the third direction, and the two semicircular arc sides may be spaced apart along the second direction. The distance between the two straight sides is the width of the waist, and the distance between the two points on the two semicircular arc sides that are farthest apart is the length of the waist.

[0061] Since the length direction of the waist shape is the second direction and the width direction of the waist shape is the third direction, L1 can be the distance between the two straight sides, which is equal to the diameter of the equivalent circle corresponding to the semicircular arc side. L2 can be the distance between the midpoints of the two semicircular arc sides, which is equal to the diameter of the equivalent circle corresponding to the semicircular arc side plus the length of a straight side.

[0062] When the mounting groove 11 is a waist-shaped groove, the outer circumferential surface of the battery 300 can be limited by the two waists of the waist-shaped groove, and the outer circumferential surface of the battery 300 is separated from the arc surface of the waist-shaped groove, thereby preventing the lateral force of the clamp 201 from being transmitted to the support cup 1 and the scale body 2 and damaging the support cup 1 and the scale body 2, which is beneficial to improving the accuracy and precision of weighing measurement.

[0063] According to some other embodiments of the present invention, the projection of the housing 10 along the first direction is waist-shaped.

[0064] Specifically, the outer circumferential surface of the housing 10 may be composed of two semi-circular arc surfaces and two planes, the two planes may be spaced apart along the third direction, and the two semi-circular arc surfaces may be spaced apart along the second direction.

[0065] A projection plane perpendicular to the first direction can be defined, and the orthographic projection of the shell 10 on the projection plane can be waist-shaped. Thus, the shape of the shell 10 is roughly the same as the shape of the mounting groove 11, which is beneficial to reducing the wall thickness of the shell 10, ensuring the uniformity of the strength of the shell 10, and saving the materials required for the shell 10 and saving the cost of the shell 10.

[0066] In some specific implementations of the present invention, L2+1.5mm≤L1≤L2+3mm.

[0067] Specifically, when L1<L2+1.5mm, when the clamping jaw 201 clamps the battery 300 and inserts it into the cup 1, the gap between the outer peripheral surface of the battery 300 and the inner wall surface 13 of the mounting groove 11 in the second direction is very small, so the risk of the lateral force of the clamping jaw 201 being transmitted to the cup 1 will increase, and the cup 1 and the scale body 2 will be easily damaged. When L2>L2+3mm, the gap between the outer peripheral surface of the battery 300 and the inner wall surface 13 of the mounting groove 11 in the second direction is very large, so the battery 300 is easy to shake in the cup 1.

[0068] Setting L2+1.5mm≤L1≤L2+3mm can not only prevent the lateral force of the clamping jaw 201 from being transmitted to the support cup 1 and the scale body 2 to avoid damage to the support cup 1 and the scale body 2, but also reliably limit the battery 300 to prevent the battery 300 from shaking.

[0069] According to some optional embodiments of the present invention, in the second direction, the maximum length of the notch 12 is 23 mm to 24.5 mm.

[0070] Specifically, the notch 12 may be waist-shaped, and in the second direction, the maximum length of the notch 12 is L3, which may be the distance between the midpoints of the two semicircular arc sides of the waist corresponding to the notch 12. In the third direction, the maximum length of the notch 12 is L4, which may be the distance between the two straight sides of the waist corresponding to the notch 12. L3 may be 23 mm to 24.5 mm, and L4 may be 21.5 mm. The battery 300 may be a cylindrical battery, and the diameter of the battery 300 may be adapted to L4, thereby ensuring that the lateral force of the clamping jaw 201 does not affect the support cup 1.

[0071] According to some other embodiments of the utility model, the mounting groove 11 includes a first channel 111 and a second channel 112 arranged along a first direction, the first channel 111 penetrates the surface of the shell 10 and forms a notch 12, and in the direction from the first channel 111 to the second channel 112, the inner wall surface 13 of the first channel 111 is inclined toward the center line of the first channel 111.

[0072] Specifically, the mounting groove 11 may be mainly composed of a first channel 111 and a second channel 112. The first channel 111 and the second channel 112 may be arranged along a first direction. One end of the first channel 111 may penetrate the outer surface of the housing 10 and form a notch 12 of the mounting groove 11, and the other end of the first channel 111 may be connected to the second channel 112.

[0073] For ease of description, the positive direction of the first direction may be defined as a direction from the first channel 111 toward the second channel 112 , and the reverse direction of the first direction may be defined as a direction from the second channel 112 toward the first channel 111 .

[0074] In the positive direction of the first direction, the inner wall surface 13 of the first channel 111 may be inclined toward the center line of the first channel 111. That is, in the positive direction of the first direction, the diameter of the mounting groove 11 gradually shrinks in the positive direction of the first direction, and the cross-sectional area of ​​the mounting groove 11 gradually decreases, thereby, on the one hand, facilitating the battery 300 to smoothly enter the support cup 1, and on the other hand, avoiding collision between the battery 300 and the support cup, thereby avoiding affecting the measurement accuracy of weighing.

[0075] Optionally, a center line of the first channel 111 may coincide with a center line of the second channel 112 .

[0076] According to some optional embodiments of the present invention, the inner wall surface 13 of the first channel 111 includes two inclined surfaces 111a and two first curved surfaces 111b, the two inclined surfaces 111a are spaced apart along the third direction, and the two first curved surfaces 111b are spaced apart along the second direction, and in the direction from the first channel 111 toward the second channel 112, each inclined surface 111a and each first curved surface 111b are inclined toward the center line of the first channel 111.

[0077] In other words, the inner wall surface 13 of the first channel 111 can be mainly composed of two inclined surfaces 111a and two first curved surfaces 111b. The two inclined surfaces 111a can be arranged relative to each other along the third direction, and the two first curved surfaces 111b can be arranged relative to each other along the second direction. In the positive direction of the first direction, the two inclined surfaces 111a and the two first curved surfaces 111b are respectively inclined toward the center line of the first channel 111, thereby, in the initial stage of the battery 300 entering the installation groove 11, the battery 300 can be prevented from colliding with the support cup 1 so that the battery 300 can smoothly enter the second channel 112, thereby being limited by the second channel 112.

[0078] In some specific embodiments of the present invention, the inner wall surface 13 of the second channel 112 includes two limiting surfaces 112a and two second curved surfaces 112b. The two limiting surfaces 112a are parallel to each other and spaced apart along the third direction, and the two second curved surfaces 112b are spaced apart along the second direction. Each second curved surface 112b is semicircular.

[0079] In other words, the inner wall surface 13 of the second channel 112 may be mainly composed of two limiting surfaces 112a and two arcuate surfaces. The two limiting surfaces 112a may be planes perpendicular to the third direction, and the two limiting surfaces 112a may be arranged opposite to each other along the third direction. The two second arcuate surfaces 112b may be arranged opposite to each other along the second direction, and each second arcuate surface 112b may be semicircular.

[0080] Thus, the battery 300 can be limited in the second channel 112 by the two limiting surfaces 112 a , while the two second arc-shaped surfaces 112 b are still spaced apart from the outer circumference of the battery 300 , thereby preventing the lateral force of the clamping jaws 201 from affecting the support cup 1 .

[0081] In some specific embodiments of the utility model, in the first direction, the support cup 1 also includes a seat body 20, which is inserted into the outer shell 10 and separated from the slot 12, and an end surface of the seat body 20 facing the slot 12 is formed as a bearing surface 21, and the bearing surface 21 is used to bear the battery 300, and the bearing surface 21 is formed as the bottom surface of the mounting slot 11.

[0082] Specifically, the housing 10 may further be provided with a mounting cavity 15, and the base 20 may be disposed in the mounting cavity 15. In the first direction, one end of the base 20 may face the slot 12 and be spaced apart from the slot 12, and the end surface of the base 20 may serve as a bearing surface 21 to bear the battery 300, and the other end of the base 20 may be away from the slot 12 and exposed from the outer surface of the housing 10.

[0083] The bearing surface 21 and the inner wall surface 13 of the housing 10 can cooperate to define the installation groove 11 . The bottom surface of the installation groove 11 can be formed by the bearing surface 21 , and the wall surface of the installation groove 11 can be formed by the inner wall surface 13 of the housing 10 .

[0084] According to some optional embodiments of the present invention, the base 20 is a conductive member, and the base 20 can be conductively connected to the battery 300 and the external component respectively.

[0085] Specifically, the outer surface of the battery 300 can be conductively connected to the base 20 through the bearing surface 21 of the base 20, the end of the base 20 away from the notch 12 can be conductively connected to the external component, and the external component can be conductively connected to the ground. Static electricity is generated during the production of the battery 300, and the static electricity on the battery 300 can be quickly released to the ground through the base 20, so as to avoid static electricity interfering with the scale body 2 during the weighing process of the battery 300, which is conducive to improving the consistency of the weights weighed from the same batch of batteries 300.

[0086] According to some other embodiments of the utility model, the base 20 is made of aluminum, which is conductive and can release the static electricity on the battery 300 to the ground through external components, thereby preventing the static electricity of the battery 300 from interfering with the scale body 2 during the weighing process.

[0087] Optionally, the shell 10 may be made of plastic.

[0088] In some specific embodiments of the present invention, a stepped surface 14 is provided in the housing 10, and the seat 20 includes a first segment 22 and a second segment 23. The first segment 22 is disposed in the housing 10. The second segment 23 is disposed at one end of the first segment 22 facing the slot 12, and one end surface of the second segment 23 away from the slot 12 abuts against the stepped surface 14, and one end surface of the second segment 23 facing the slot 12 forms a bearing surface 21.

[0089] Specifically, the inner wall surface 13 of the housing 10 may have a step surface 14 , the installation cavity 15 may be a cylindrical chamber, the installation cavity 15 may be connected to the bottom side of the installation groove 11 , and the step surface 14 may be formed by the groove bottom surface of the installation groove 11 .

[0090] The seat body 20 may be mainly composed of a first section 22 and a second section 23. The diameter of the first section 22 may be smaller than the diameter of the second section 23. The first section 22 may be accommodated in the installation cavity 15, and the second section 23 may be disposed at one end of the first section 22 close to the notch 12. Figure 3 and Figure 4 As shown, the lower end of the second segment 23 may abut against the step surface 14 , and the upper end of the second segment 23 may be formed as a bearing surface 21 .

[0091] Therefore, the seat body 20 is composed of the first segment body 22 and the second segment body 23 , and the seat body 20 can be limited in the first direction by using the step surface 14 in the housing 10 to abut against the second segment body 23 .

[0092] According to some optional embodiments of the present invention, a mounting channel 24 is defined in the seat body 20 . The mounting channel 24 extends along a first direction and passes through the seat body 20 .

[0093] Specifically, the base body 20 is provided with a mounting channel 24 extending along the first direction, and the mounting channel 24 can pass through both ends of the base body 20 to form an opening. The mounting channel 24 can allow a locking member to pass through, and the locking member can lock the support cup 1 on the connecting plate 3 connected to the scale body 2. When the support cup 1 needs to be fixed to the connecting plate 3, the locking member can pass through the mounting groove 11 into the mounting channel 24, and extend from the mounting channel 24 to be connected to the connecting plate 3.

[0094] Optionally, the locking member comprises a bolt.

[0095] The embodiment of the utility model further provides a weighing mechanism 100, which comprises: a cup 1 and a scale body 2. The cup 1 is the cup 1 according to any of the above embodiments, and the scale body 2 is connected to the cup 1 to weigh the cup 1. Optionally, the scale body 2 can be an electronic scale.

[0096] The scale body 2 may also be provided with a connecting plate 3, and the support cup 1 may be fixed on the connecting plate 3. For example, the seat body 20 in the support cup 1 and the connecting plate 3 may be tightened by bolts.

[0097] The shell of the scale body 2 can be a metal shell, and the metal shell can be connected to the ground. The base body 20 can be conductively connected to the ground through the connecting plate 3 and the shell of the scale body 2, so as to conduct the static electricity of the battery 300 into the ground, thereby achieving the static electricity removal effect on the battery 300.

[0098] Since the support cup 1 according to the embodiment of the utility model has the above-mentioned technical effects, the weighing mechanism 100 according to the embodiment of the utility model also has the corresponding technical effects, that is, the mounting groove 11 limits the battery 300 in the third direction to prevent the battery 300 from tilting, and at the same time avoids the contact and force transmission of the clamping jaw 201 to the mounting groove 11 in the second direction when clamping the battery 300, thereby avoiding the lateral force from being transmitted to the support cup 1 and the scale body 2 and damaging the scale body 2, which is beneficial to improving the accuracy and precision of weighing measurement.

[0099] The embodiment of the utility model further provides a liquid injection device 1000, which includes: a weighing mechanism 100 and a conveying mechanism 200. The liquid injection device 1000 has an upper material position, a weighing position and a lower material position, the weighing mechanism 100 is a weighing mechanism 100 according to any of the above embodiments, and the conveying mechanism 200 is used to convey the battery 300 between the upper material position, the weighing position and the lower material position.
